Thanks a lot for the tutorial. Worked nicely on my CSRA64215 working in I2S mode with an ES9023 DAC (Nobsound design). Even though the I2S lines are shared with SPI and used with an SN74LVC125A buffer/level translator to isolate the ES9023, it works fine just connecting the SPI signals on the solder points of the smaller BT daughter board. An important note though is that the full board also features power supply with LDOs. I didn't dare backsupplying these with 3.3V from the programmer and desoldering these are very hard to do without ruining other stuff - so no 3.3V is supplied from the programmer, but from another USB port. A bit dangerous due to possible differences in ground levels, but got lucky :-) Should have measured first, but didn't hehe
Nice work! Hit me up with an email at lipton5001@yahoo.com
I do have some questions
Thanks for your video! Many changed in software part, but its not important! Great video!
Dariee, thank you so much from Spain!... nice video ;-)
+victorius2006 :D
Is there a was to change the udio prompts? So I can use a custom soud when the module is paired?
hi, do you know how to use multipoint on csr8645? I need to connect two phones to one module
how do you use the on/off pin? bc i tried touching the contact for POWER_EN with the bus voltage, but i cant get the module to shut down without disconnecting the battery.
Thanks for the help man!
Btw I had a CSR8645 board (f-3188 mounted on breakout w/ audio amp) from Aliexpress and mine refused to work until I UNHOOKED the SPI_Enable pin. Just in case anyone else is having trouble.
quite strange, can you post a link of the exact amp ?
Darieee hi. Can you tell me your facebook? I have some problem ask you. Help me please! Thanks
Feel free to ask here :)
This worked great on a CSR8675. Beware that some SPI interfaces have different pinouts even if they look the same.
Hey, me and a few friends have just gotten started with the 8675, and are having issues with finding the proper software - could you maybe perhaps help out with some pointers ?
Just googling trying to find a module to edit with, have you ever seen Qualcomm DK-USB-SPI-10225-1A at digikey? it appears to have 7 headers on a board and a micro USB connection......In your opinion could you use something like this?
hi, does anyone know, if this also works with the qcc3005 chip, because it seems to have the same pinouts, but on the qualcomm website it says, that it support ota updates..
where can i get the csr8675 usb drivers? please i cant find it anywhere
I've got a module with Qualcomm QCC3005. When I connect to it using my Android phone, it doesn't show "phone calls" on the menu. When I have a voice call while I'm connected to this module, the call is not output via the speakers connected to the module. Is it possible to enable phone calls?
Great vids I've done this with these CSR chips. theres not any videos on these so these are great for people that don't know where to start
tell me about it .. spent about 4 months struggling with 4 CSR8645s in my iPhone ... glad I could help :D
I've made a few bluetooth speakers for people and they they've wanted to know how I could name the module. Now I'm just going to send them to your videos. thanks :D
+Marshall Smith you’re welcome ! I’ve seen some of your speakers, nice work ! Where do you get your speakers from btw ?
The first speaker I built with MDF on my channel, I'm not very proud of. Its a little rough with the vinyl wrap, it was really half assed lol. I usually get the speakers from my grandfather. He's an engineer at the University of Alabama and tells me when they're just throwing away stock. They literally throw away new unopened things... But the drivers from the light oak colored speaker came from a Harmon/Kardon 2.1 computer set. I really enjoy building these speakers but next year I am moving to England where my wife lives....I use my dads workshop with all his tools and equipment and I won't have any tools of any kind :(
I'm quite sure you'll find the tools you need if you're into this :D plus .. now that we can rename the bluetooth modules .. really makes the whole proposition more attractive
Thanks for the video! I purchased a CSR8645 module and the CSR USB-SPI. When I tried to connect with PSTool I received the next message: "Error detecting chip type (Read failed on USB-SPI)". Can you help me please? Thanks!
Hello friend, good and informative videos, tell me how to reset the PSR and HEX settings if there are no stock firmware? where can I get them? and the consumption of the module is oklo 200-300mA is it normal? the chip is warming up ....
is the 10k resistor nessecary?
Hi, did you alter any settings in your CSR8645 Dump included for download in description?
I have the same module (F-3188) and it works but after a few minutes of playing music it shuts down the bluetooth connection...
it should be quite stock, only the name is changed ...
check my how to turn off the mic video : use the ConfigTool I linked in there to fumble around with the settings ...
!! actually, before that, in PSTool go to Restore All Factory (or something like that) unplug and replug the board, then flash my .psr again
(when you merge PSRs it's only additive, so, if you want to remove a setting you'll have to erase everything first)
Can we rename using USB_DP and USB_DN pins instead of SPI?
Can’t we use normal USB cable and connect D+ to USB_DP, D- to USB_DN and select the USB option in ‘choose transport’ option in PSTool? If yes what extra peripherals should I need to take care of (like do I need to pull up or pull down any pins) ?
Полезный видос)
Hi Darieee, unfortunately the USB to SPI i bought has not pin to select the signal voltage, and i checked and it is 3.3V. Do you know hot to deal with that? When i connected it to the 8635 module, the signal was not looking good. Sometimes it was going from GND to ~1.8V and other times it was going from 1.8V to 3.3V. Please let me know if you have any ideas. Thanks.
I've read online that the CSR chips accept both 3v3 and 1v8 - so, theoretically it should work as long as you connect all the pins properly and not forget the EN :)
Hello Darieee, I was wondering if you could leave the wires attached to the board and still connect VCC and GND for ease of future programming (I’m using a 10 pin IDC)?
yeah, what you want to do is for sure possible; I do it all the time
you must not connect VCC in that case though
everything else just as per usual
its possible we can extract firmware from CSR8675 cheap and writ it to empty CSR8675 ? (HARMAN KARDON GO + PLAY mini firmware )
Hi I bought the CSRA64215 the data sheet say that have a usb and uart interface, You have any idea about how config this module?
I did try out one of those modules (mine didn't have audio though so .. dead out of the box). The procedure is fairly similar; PSTool works, but for disabling the microphone/setting the equaliser you'll need different versions (the ones I linked in the other videos won't work).
If you want to just rename it, then you're good to go, if you want the other stuff, I could upload all the programs I have
amazing! i tried to conect a ttl-usb adapter PL0323 to my bluetooth headset with RDA 28 pins eeprom chip.
the bluetooth headset have only gnd tx and rx. i tried to connect with OVC3868 software however the doenst seems connected . do i need to connect a 3.3v battery to the ttl-usb adapter ?do i need to disconnect the internat battery of the bluetooth headset? please help!!
I really have no idea - I always used the CSR branded usb spi converter
Hi, Thanks for the tutorial. Which pin from the USB SPI connects with the BAT+, is it the 1V8 or 3V3?
3v3
Good morning, could you recommend a chip that can be used to modify the bluetooth name and has the DSP function?
csra64215 or qcc3008
Awesome!
Thanks for the video.
Can I use common USB ISP interface or it has to be CSR one?
There's some hacked drivers that many people claim to have had success with
I would however strongly advise you get the CSR programmer
Hi! Great tutorial! I'm trying to make a bluetooth audio transmitter to transmit audio to a remote bluetooth speaker like JBL-GO, and using CSR8630 module, but seems like it can work only as a bluetooth "receiver" (speaker)? Or I can set somehow it's role as a master (transmitter)? Do you have any ideas? How can I email you?
I've absolutely no idea how to achieve this unfortunately.
Quite recently a dude on the EEVBlog Forum asked about the exact same thing : perhaps you guys could share notes (and maybe even post a video once one get it working)
Here's the link
www.eevblog.com/forum/projects/programming-off-the-shelf-csr8635-module/new/?topicseen#new
Darieee thanks for the suggestion, I will take a look!
Does it work with every bluetooth module ?
Hi Darieee, i have a broblem with my board Tda7492 with 8635 blue chip. After i channge the Name, Eq, sound (i use config tool) Now my board cannot use 5 control number of the board (play, next, pause, vol-, vol+)
Can you help me how to fix it, or reset factory is dangerous😢
@dariee can you recommend any audio Transmitter modules that can be programmed in same way, I just see CSR8645 receivers for sale?
if you search for csr8675 you will find a lot of transceiver devices with a switch to go between TX and RX
the 8645 is quite old by now, either upgrade to the csra64215 to retain programability, or go to the csr8675 and fight the demons yourself (or just leave it programmed as it is)
@@Darieee yes have seem some CSR8675 reciever/transmitter modules on Aliexpress, one even has what looks like the SPI header broken out to a header on the board www.aliexpress.com/item/32912822521.html
Hi Darieee, is it possible to use either the CSR8635 or CSR8645 as a BT Transmitter? Im trying to make one of those BT transmitters with a 3.5mm input. Once I figure which chip to use, I plan to use a micro controller to send audio to multiple BT headphones. I'll connect 3-4 of the CSR transmitters and pair them to 3-4 BT headphones/ speakers. This is for a school project. Thanks
That sounds like a rather challenging project
I don't think the 8645 / 8635s are powerful enough; the CSRA64215 however does have 2 high quality ADCs, and can thusly accept analog stereo
How to turn that into a transmitter ... is a firmware level challenge I think - for which tools are very sparse, and I've never had the need for (what software I do have I have posted in my CSR related videos - and if you want, I can send you my entire stash)
The way I would go about this, is buying a few types of Bluetooth transmitters off of aliexpress/ebay, and trying to reverse engineer them
In any case - if you manage to get stuff going, I would be very interested in your findings too ! (as I sure is the community gathered around these videos)
Darieee thanks
Hi sir. I recently bought one of this module and i tested it.
1). It is not switching off automatically when no device is connected. Did you tested this case?
2). I am building a Headphones in which I need an op-amp of 5W atleast. Can you suggest me better Audio amplifier chip which is suitable to accept differential input and produce differential output.
Thanks and appreciated.
I tried two 50+50w amps they work but the 25+25w don't so i assume the spi pcm or spi en is defective.
I'm gonna order a new one when I get the chance.
Yeah, weird stuff does happen sometimes, maybe they terminated the programming pins on the amp board or something ..
Hello friend, thanks for this, is there a way to change the start up sound or connection sound notification option ???
yesyes - you need to use the configtool for that
I have videos on that topic as well
any idea if you can change the startup\initiation sound on these modules? looks like they are quite customisable....for example a bottle speaker when turned on it makes the bottle opening sound etc
yup - you can for sure change them -- I always do
check my other CSR videos on how to do this
you need to use the ConfigTool (I think it's in the Disable Mic video)
@@Darieee whats the reasoning behind the 10k resistor? is that because you are using a 12v version?
nono
that EN pin needs 1.8v so, feeding it the 3.3v is a bit much
a very quick and extremely dirty trick is to use that 10k resistor to limit the damage
Hey mate great video. Is there an option on the program to edit the pairing sound?
Not in PSTool, for that check my "disable mic on csr8645" video
There I use the ConfigTool, and with that you can even upload custom powerup sounds I think, I always change them with some very short and subtle beeps
Thank you for the video. A question: if I want to configure a BT Headset, should I connect it through this adapter? Or is there a way to do that through USB?
most likely you'll need the adapter - I'm quite sure your headset doesn't include an SPI to USB converter just for the off chance a user wants to program it
Darieee Thank you!
Is there any schematic available for the F-3188 modules?
I haven't found any .. would be kinda nice, let us know if you find any - I'll add it in the description
Darieee wenn I find one I'll share it for sure!
Hello, may be you know why csr8645 switches on with both leds turned on and stays in this mode?
hmmm, no .. not in particular ... maybe it's not getting enough voltage ???
check BAT and see what voltage it has on it :-/
@@Darieee I use laboratory voltage supply set to 5V. Max current is about 2A. Do you have any ideas?
well, the CHIP is supposed to get between 3 and 4v2 ... so ... 5 is quite on the high side
Hi Dariee! Thanks for the excellent explanatory video. I have a similar board with the same CSR8645 chip. I want to use a momentary switch to turn on/off this board, do you have some tip on how to do that? Thanks.
Mmm, not really, why do you want it turned off though ? And why won't a normal switch cut it ?
I want to use this board in a portable speaker. I normal switch can cut it, right, but I want to use a push button. The normal switch will not look nice in this project, since usually they are larger then a momentary switch. From the datasheet I see a PWR_EN pin that this functionality is supposed to work.
I am asking on the diyaudio forum, too. I think I have to change the PSkeys, maybe, but I havent arrived at this point yet...
Thanks for your reply.
I want to use this module only for music when it's paired with my phone.
So phone calls must not through this module is there a way to fix that ?
I know that you can change the settings on your phone but I don't wanna do that every time.
Yeah, check my "CSR8645 disable mic" video.
I'd also suggest using the way more modern and more powerful CSRA64215
@@Darieee thanks for the quick response
Hi bro i want to know that is there any button which will answer or reject call on phone?
mmm, you can program that kind of behaviour with the ConfigTool (check my disable mic on csr8645 video) for that
I would recommend moving up to the csra64215, and for that I also have videos where you'll find the ConfigTool linked (they are different programs)
Which part of the Germany are you from bro?
Hi, I am now playing around with csr8645 modules and i came up with the idea of building myself a pair of wireless headphones. The problem is that my PC does not have Bluetooth. I managed to wire up the module to act as USB sound card, but this way it only outputs audio through its analog differential audio outputs. I wonder if there is a way to connect two csr8645 modules together using bluetooth?? I would like the setup to be: PC -> usb -> first CSR8645 -> bluetooth -> second CSR8645 -> analog out.
Do you have any idea if this is even possible with csr8645 modules?, or any different csr bluetooth modules?
I'm quite sure it's possible; I would buy a chinese csr8675 bluetooth transceiver and check out the configuration of that
have you by the way been using the ADK ?
@@Darieee Nope, I have not been using any ADK. I only have PSTool and ROM Config Tool and I had no luck setting this up with these two software tools so far.
Hi! Hoping you could help advise on an un-related CSR8645 project?
I'm trying to do this mod (www.norwegiancreations.com/2017/09/modifying-a-portable-ipod-docking-to-bluetooth/) but ended up with a board with a different pinout. (Theirs looks more like yours.)
They made connections at "outL", "outR", and "agnd" which i can only assume is... audio ground? My board has connections labelled "L+", "L-", "R+", "R-", "mute", 3 blank ones, and then "m-" and "m+". I can't figure out which of my connections correlates to which of theirs. I also can't figure out where/how they intend to connect the green "bat" wire they added.
the link doesn't work on my end
they are using a single-ended signal - meaning ground & channels
what you have is a differential channel - meaning both channels get 2 wires which are all independent from system ground
you need to buy a csr8645 or csra64215 or qcc3008 board with a DC-DC isolating converter - those have a headphone amplifier on them which converts the differential signal into a single ended one
If u don't have a 10K resistor, I'll try to make a video without one tonight.
sorry if I had u all waiting.
You can use a resistor between 10k-100k without problems
Hey there! At 6:32, do you mean I am supposed to connect jumper cables between V-VCC and G-GND? I am not sure what to do.... Or can I simply connect V to the 1v8 on the USB-SPI and the G to GND on the USB-SPI ?
Connect V to 3v3 and G to GND
What I mean is, and I mean all of the following for the CSR8645 Module, that the round pad marked V is directly linked to the outer hole marked BAT+
And that G is directly linked to GND
So you are free to solder to whichever is most comfortable :)
Darieee man, you're the best! Thanks for the quick help my dude. Rock on!
Happy to help dude ! Good luck with your project !
I remember back when I needed help and there was jack shit available .. /insert back in my day quote/ (like, 1 year ago though)
@@Darieee unclear. in the vid you say you used 1.8V, not 3.3V. Here you're saying to use 3.3V?
i use a 3.3V bench supply (to power the CSR8645). Unclear where to connect the POWER_EN, BAT, SPI_PCM, and TX pins on the CSR8645.
Should i connect the 3V3 pin on my USB/SPI adapter to my bench 3.3V?
thx!
3v3 .. don't think I said 1v8 though
The 64215 module i have is similar to the one at the right. But your picture does not have pin out label. Which one is 3v3？I have anotber silly question， does these chip included a DAC？
Have you connected yours to any speakers/headphones ? Given the module should SPEAKER A P and SPEAKER A N and for B as well ... I'd assume it does have one (my csr64215 module doesn't produce any output however .. for some reason)
Coming back to your question, it seems the CSRA64215 motherboard is exactly the same as for the CSR8635 (I've asked a few sellers to confirm this but the component layout in the CSR8635 seems 100% identical)
So, here : bit.ly/2ux5CJG : VBAT would be 3v3, and the rest should be clear (I assume you have the same programmer as myself ?)
Darieee the one I have us this a works with no problem. m.ebay.co.uk/itm/CSR64215-Module-Wireless-Bluetooth-4-2-Audio-Receiver-Board-HiFi-Lossless-APT-X-/272768136730?_mwBanner=1
alright .. really does look like a CSR8635 motherboard ... let me know if you manage to program it ...
Regarding the analog output .. your board does have the one large chip ... That seems to be for the analog audio output from what I can gather
I do think the CSR chip already included the DAC processing. The audio output from the chip is analog and the extra circuit (included the DRC632) in the board is analog amplifier.
yeah, that's probably there to convert the signal from differential to single-ended
so, did you manage to rename it ?
Hi, im getting the Error: Error detecting chip type (Read failed on USB-SPI).
Ther are 2 Points im not sure if ive made it correctly.
1. The SPI_EN is directly connected with the BAT+ (1.8v) ?
2. It does not need the 5V from the normal connection points?
so basicly i just need to know how or wher to connect SPI_EN, BAT+ and GND. And if i need to use the normal VCC and GND Connections. Thanks.
Thanks
SPI_EN can be connected to the 1v8 line (that is not the same as the BAT+ line, BAT+ should be around 3v3 or even 5v)
if you connect SPI_EN to anything more than 1v8, do so via a 10K resistor
@@Darieee Mr Darieee is it possible to run any of the JBL or other usb speakers without bluetooth chips? I love music this convenient but have students in my school that caters of EHS sufferers and dont want to deny them tunes while working and learning outdoor activities. We wire up everything and provide correct insulation as much as possible.
About CSR86XX Config Tool... Have you tried loading from the device before changing the name of it and flashing it to the chip?
Then again, the Config Tool is kinda buggy, and possibly has compatibility issues.
If you run it under a 32bit Windows 7 it runs flawlessly - and yes, you can load from device, change the name, then write to device
Don't know if you have but I actually do use that tool to disable the microphone in another video :)
Hi Darieee,
I have such a problem: computer finds immediately the CDR8645 and I make dump and change name without any problem, BUT after that when I try to connect my phone to the bluetooth, it cannot find the bluetooth. I tried with 2 CSR8645 chips as I initially thought that the first one has some defect. But the same problem is on the second one too. Is there any settings that can cause this? Any idea?
uuuf .. no idea .. so, you're just using PSTool ???
Darieee Yes, and PC Tools finds it immediately and everything is find with it. But my phone cannot connect with the bluetooth.
So ... try downloading my DEFAULT/STOCK dump for the csr8645 ... aaand, try it after flashing that
To flash it properly:
1. PSTool: connect to board -> Restore All
2. PSTool: merge my default dump
See if it works fine
then modify the settings of that and see if it works
I don't have SPI_EN but POWER_EN i use 8635, someone help. I do have vbat too
Great video!!!
I have an issue with my module. Hope you could help.
I uploaded the code using BC_HS_Configurator, in that i changed the following option
Timers ------>Auto Power On Timeout(s) = 0.
Now my module is not starting. It is not detected in the ps tool or any other configuration and testing tool. Can you guide me how i could restore the factory settings to the module?
ooowhyeah - there indeed are some setting one shouldn't change too much
try connecting the COM pin (internally derived 2v2 rail or 2v5 I don't remember) to the PLAY PAUSE NEXT etc ... individually first and then maybe more at once
and then applying power to the module
that sometimes takes it into a reset mode and you can reflash it (go into PSTool and click Restore All
however !!! this doesn't always work :(
Hi, I have the same board. Since yesterday it shows me at connecting CSR BC7. I don't hear any more sound. What could be the error?
you at some point hit 'Restore Factory Defaults'
that deletes all values and sets back 'some' to a default value
just hit merge with a default dump and stuff should start running again
@@Darieee Hi, I don't quite understand. How exactly should I do this? Is there a combination? Do you have a guide? Thank you.
Will this work with atmel usb isp programmer?
There's some stuff on github from a dude that made that work .. and some people in the comments of either of the 3 videos I have on the 8645 have gotten it to work ... but not easily ... and you'll never know wether your problems come from your programmer or the chip or something else
I would highly recommend forking over the 20$ for a proper CSR programmer
I also have a csr8635 on a tda7492p.
Can I use the same connections?
+MegaSpotman if the board you have on there is exactly like the one I have in the thumbnail, than yes, but be careful of the pin numbers; I have a discussion on this somewhere in the comments (and initially gave the wrong pins so beware of that as well)
Darieee Awesome
Thanks
also I've found some external pins, i guess, for the spi usb on the amplifier for the csr8635 but I'm not sure if I should try it. I'll link a vid soon for u to check out.
Greate viedeo,
do anybody know how to enable I2S output?
Thanks for your great Tutorial. Do U think it will Work the Same way with a CSR8633?
yeah, PSTool is super compatible
is there an 8633 ?
Hey Darieee, great vids on CSR's!Exactly what I was after. I'm working on a project where 8645 is involved and I wanted to change a name. But also - more importantly - I need one of the IO pins to go 1/0 accordingly to BT activity. Ie when BT is active I need the pin in log 1 and when BT is idle I want it 0. Any thoughts on where should I look in the config tool? Thanks and keep up the great work!
Glad I could help, I remember it took me half a year to source the corage and parts to rename the ones I had, can't let that happen to more people
Firstly, the CSR8635 and CSRA64215 (check the pinout) modules have an Amp_Enable pin which is a preconfigured IO pin that does exactly what you want
Otherwise you can go into the Config Tool and I'm quite sure you'll manage to find the IO section (I don't know this by heart especially since when I needed such functionality I was a bitch and programmed the LED light .. somehow that seemed easier at the time)
In any event, if you still can't et it working I can fire up my config tool and take a look myself
Btw what project ?
Hey Darieee,
thanks for that. CSR programmer is on its way to me so once I have it in front of me I'll give it a try. Maybe I'll grab your brain later if I fail :-)
Yes I saw it on CSR8635 pintou you attached to one of your vids and I was like yeah this is what I need! "Unfortunately" I have quite a few 8645's already so I want to utilize these. I'm building custom infotainment system for BMW car. It's a replacement to stock Central Information Display that is pretty old and can't do much. I ripped off original screen and fitted Android tablet. I'm building a dedicated ECU for the screen and one of the modules I want to implement is BT handsfree. Handsfree is supposed to provide "interrupt" signal to mute ordinary audio and swap audio source to phone. Along with BT handsfree it will host USB stick (as audio/video repository), reverse camera, atmega based watchdog (that will control clever power management, active CPU and battery cooling, control of GPS tracker etc etc), OBD interface and I still have one USB slot free. Maybe I'll try grab a little joystick and will try to emulate HID with arduino so I can control the tablet with mouse.
Thanks for your help,
Jan
Holy crap that sounds awesome, would love to see a video or some pictures of it sometime
Also, couldn't resist checking.. In ConfigTool (you can load it without the programmer just to see what's there), you have the Input/Ouput tab, aand yeah, a lot of IO goodies there
Perf, thanks a lot! Yeah happy to show/share anytime. Currently I have the flip display part done. It was more about physical fitting of the tablet, and one nice PCB with atmega 328p that controls the stepper motor for screen positioning. The rest is currently at my desk - it's arduino 2560, usb hub, video dongle etc etc. Currently trying to figure out how many inputs/ports of Arduino I need and then I'll build custom PCB and job done. It is also connected to BMW's communication BUS and is listening to the messages and does some stuff accordingly (gps tracker arm/disparm, triggers alarm if door opens when armed, emulated CD changer so I can feed audio to car's head unit - inputs are only active when cd changer is present, I can detect ignition, write text on radio display etc :-)
dayum, that really sounds nice, you should definitely make a video showcasing it when it's done, and please let me know what that goes up, wouldn't want to miss it !
cela peut être fait sur la puce bluetooth CSR8635 de la même manière que dans la vidéo
So you're Romanian! thanks for these videos, I might give a try to play with the EQ on this CSR, did you get the results you wanted? also do you know if there's a dynamic bass boost option(for lower level listening) and compression for louder volumes to avoid distortion?
Cu placere :D foarte multumit, boxuta aia de lemn se auzea foarte prost inainte sa reglez equalizeru, acuma se aude perfect ... Stiu ce vrei ... asa are apple pe Hi-Fi ... volum independent la bass, si ... paaarca era o chestie cand configurai DSPu cu ceva bass boost, da n-am incercat
pentru proiecte mai pretentioase uita-te pe site-ul sure electronics in caz ca nu stii de ei. au un modul DSP separat dar si cu amp pe aceeasi placa, iar softul de configurare/programare e destul de complex cu multe optiuni. eu am unul dar trebuie sa ma mai joc cu softul ca pana acum rezultatele sunt asa si asa, probabil din cauza mea. varianta asta cu DSP-ul din CSR imi place pt ca-i ieftina si compacta, probabil folosita in multe boxe BT de pe piata
am auzit de ei, par sa vanda chestii de calitate; singura mica problema cu equalizeru din 8645 e ca introduce destul de mult lag ... fara equalizer ai ceva gen 150ms, ceea ce nu prea se observa, cu equalizer n-am masurat da nu prea-i folosibil decat la muzica. Chipurile noi au si mai mult de 5 parametri, deci poti sa le setezi mult mai precis .. da .. pana ajung alea pe module asa integrate ca astea, mai avem de asteptat
Awesome tutorial! Thanks for this. One question though...My module is attached to an amp board, so I should be able to just power it through that and skip the +/gnd connection from the programmer and the resistor, right?
+Brandon Terry the resistor you'll not be able to skip: that tells the CSR chip that it's being programmed. I also would advise against having the board be powered separately, it's only 2 extra wires :), with enough flux, patience, and obviously, more flux, you should be fine
Darieee
Ok, that makes sense. I appreciate your help.
+Brandon Terry no worries ! Good luck with your project !
Ok, so now that I look at it, I have an 8635 instead of an 8645. I'm thinking the same pins need to be connected, but the only one I don't see is the SPI_EN. Mine has a pin for SPI_PCM. Would that be the same one? Sorry to bug you about this again. I just don't want to blow anything up lol
+Brandon Terry I would think so - that one you connect to 3v3 with a 10K resistor, so it's quite safe even if it's the wrong one; I would expect it to be the enable though
This is the only way to configure this chip via a spi-usb gateway?
pretty much ...
Can you program it with a arduino uno as an SPI interface?
I'm quite sure it is possible - but I'm not aware of any library that would do it. Furthermore, from what I've read CSR (now Qualcomm) uses some weird crap too ... and yeah, you'd need to interface with their antiquated software ... For 20$ it really isn't worth the hassle.
However - if you really are on a tight budget - you may use are regular STDI adapter : github.com/lorf/csr-spi-ftdi/blob/master/README.md
Someone in the comments of one of my 3 videos on programming these CSR8645 modules has done that successfully - perhaps you can find the thread and ask them for more details there :)
Again though, I would very much recommend one of the 20$ programmers : those are guaranteed to play well with most CSR chips
you can just modify dump and flash it via ch341a
Hi Darie,
I bought a pair of chinese Bluetooth earphones. They use the CSR8645 board, which supports the AAC Bluetooth codec. However, only the AptX codec seems to be enabled. My computer supports AptX, but my phone only supports AAC and so will default to SBC when using the earphones. Can I take apart the headset and use this method to the enable AAC codec? Will the pinouts be already be in use connecting the board to the other components in the headphones, such as the control buttons, antenna, and so on? Sorry, I'm a noob at this. Any advice would be greatly appreciated.
yeah, you should be able to configure it no problems
check my "disable microphone on csr8645" video - you'll be using the tool I showcase there
quite curious now - what headphones :) ?
Thank you! :)
I am using this cable from AliExpress: www.aliexpress.com/item/2017-New-FAAEAL-BT-Wireless-Bluetooth-4-1-Cable-HIFI-Earphone-MMCX-Cable-Support-Apt-X/32814252995.html
My earphones (Tennmak Pro) use the MMCX connector for their detachable cable, so I can plug them into this Bluetooth cable to make them wireless. Works pretty well, besides the lack of AAC codec and the battery low warning sound being WAY too loud. Both of these problems I can fix thanks to you.
I may try turning the master gain down a little bit, as there is an audible hiss when using the cable and the lowest volume level is not low enough for me, while the highest is louder than i'll ever need. I assume i'd be using the tool in this video? Or would the master gain be set using the EQ tools in your other video?
Master gain you set with the FrontEnd (equaliser video) and beeps are always set to be retardedly loud, also in ConfigTool (disable mic video), it's Volume for Alerts or something, I'm pretty sure I mention it there as well ... it's the first tab somewhere in the top right quadrant
If you can show me some pictures of how these headphones look inside ... it seems the modules are just as wide as the 8645 chip ... do they have programming pads ?
Perfect, thank you.
I'm planning to open up the headset over the Christmas break when I have some time off from work. I can send you some picture of the insides then.
Awesome, good luck !
Do i need the USB-SPI from CSR or could i use a generic one? thanks
It's significantly easier when you use the CSR one; there's version available for ~12$ now though, so, keep that in mind
because of where im at, its going to take a while before i can get nmy hands on the CSR interface, I guess theres going to be trouble between the inteface and the blue suit.? any ideas of what i can encounter? any way u helped alot already, i didnt know where to start! thanks alot
Mmm, if you go through the comments on my 3 videos on the csr8645, quiiite a while back (perhaps even more than 1 year ago), someone was actually using one of those FTDI programmers, and had gotten it working, they should be able to help
I've never used anything else (and would suggest ordering one just to be on the safe side)
My 12v CSR8645 plays a beep/tone every few minutes. Any idea why it does that? Could it be a low voltage warning?
Yes, you're feeding the 12V dc dc converter
Darieee Thank you!
You're welcome !
Hi Darie, how to set a pairing password for this module?
I have no idea .. I think passwords aren't used much any more though
Hi can you help me please... I have connected my csr8645 whit USB->SPI converter to my virtual machine win 7 32bit. but when I open PSTool and connect my pcb, I receive the error message: "Error detecting chip type (Read failed on USB-SPI)". What ca I do? I have try everything, connection are OK
that's usually a problem with either
1. you not driving the SPI_EN pin correctly
2. some connection is not perfect and the software can't talk to the chip ...
test your cables, measure all voltages ... thrice 🔥
@@Darieee I have connected the SPI_EN pin with a 10k resistor to the 3v3 line and there are 2.8v on SPI_EN pin....

I'm back at it again.... your link for this car chip with the breakout board returns with a page saying it no longer exists! I have someone that wants me to add a more powerful amplifier to their speaker and I think I'm going to take out the bluetooth/amplifier combo thats in there and use one of these and TPA or a YDA. You wouldn't happen to have an eBay link for one without the amplifier? Every time I search I just get the ones with the 5W+5W amplifier onboard.....
you'll have to tell me which link in particular you mean - I checked a few and they seem to work
in eBay, write csr8645 12v -5w to exclude the ones that have 5w in the title
also if you're building a portable speaker, you should get some dc-dc boosters to make sure the bluetooth module always gets it's 12v
Thats weird the link when I clicked it didn't work yesterday. I probably should've reloaded the page... and thats exactly what I typed in eBay to search yesterday haha. I was thinking since these Chinese boards can be crap and you found a good model I would just buy from the seller you bought from. But alas I feel dumb lol

Nah, I've bought from many suppliers, in this case it seems fine, only HYT seems to be making these, and all I've gotten so far were fine
i have lattice HW-USBN-2A programmer do you think it could work ?

@@Darieee ok thanks i have order programmer as you recommended. one more question. is there any way to combine 2 csr8645 modules together over Bluetooth then play from one phone or tablet over two Bluetooth speakers ? hope you got point.
Hey, I recently got a headphones which for some reason have equiliser enabled by default. I want to make it flat. Could you please help me with if I need to hook the 10k resistor in my case. On the headphone board ( which is already battery powered,) I have this pins - CSB, MOSI, MISO,CLK,GND1 and FCM ( which I don't know it's purpose)? All 5 even the FCM have white circle marks without the GND, so I guess are used. Thanks in advance.
P.S. The chip is CSR A64215 (A11U) 552CJ
Which headphones did you get ?
Try first without connecting the FCM, and then try hooking up a 10K resistor between VDD and FCM ... usually the SPI_EN pin (which everyone names differently) is rated for 2v2 or something like that, but with a 10K resistor you can give it 5v as well
@@Darieee It is mixcder ms301, they have awesome speakers, which I mounted on other headphones just to be sure it is not from them, the highs on ms301 are muffled with stock equliser setting. I could upload photo for you to see the board if you want?
Was just curious what other manufacturers are nice and label the pins; do let me know if you manage to reflash it
Oh and - do check my csra64215 videos - there's other programs you need to use for it
@@Darieee Thanks for the quick response, I will notify you if break or not break my headphones in the process hah!
But from the pinout， pin 16 is 1v8 but there is no 3v3. Is your BAT+ connects to pin 16？
+Brian Fung BAT+ is the 3v3 in .. well, it goes up to 4.2 and down to 2.7 or something
Darieee , I am trying to do the same for csr64215. So I do not have a same exact module u have. I can only find a pin out labelled 1v8 but no pin out labelled 3v3. Should I take 1v8 as BAT+ then?
Alright, the pinouts are in the description, as well as the suitable programs.
Please let me know if you can get ANALOG audio directly out of the BLUE CSRA64215 boards :) I have one (like the left one in the pinout picture) that produces no sound
My module is a little different from what you have shown. It works with no problem but I just want to change the "friendly name" of it.
Thanks for tutorial, but I have a problem, my usb/spi converter isn't found by bluesuite, when I connect it in my computer the power led turn on but bluesuite don't found any port. any ideas ?
+corentin baron I'm assuming it looks exactly like mine ? What Windows are you using ?

thank for answer, in my computer I haven't the eject icon but it is in my peripheral manager... disturbing...
so I test on win10, bluesuite detect it, but now, I have an error "error detecting chip type" .
Is it possible that I got stuck in the connections ?
Not sure to be clear, I don't speak english very well ^^
+corentin baron your english seems quite fine :D - have you tried running a virtual machine ? Check my setting the CSR8645 equaliser video, I go a bit more in depth on that there (and there's a very nice guide linked in the description on how to achieve it); it might also be that you haven't connected the module up properly, or some pins are shorted out, have you made sure that's not the case ?
HI darieee! Can i connect the SPI_en and BAT+ without a resistor?
nope - that would be a very veery bad idea
@@Darieee and if I use a bigger resistor? A 12k resistor?

i noticed your module broadcasts battery level. do you know how to configure this feature?
+Sergey Sereda the best way to do this is to use my dump (this'll never stop sounding weird :)) and see if it enables it on yours; although, on my iPhone it shows about 3 type of icons ... headphones with battery, bluetooth with battery, and sometimes even just the bluetooth symbol, so, quite ureliable; also the readings the unit gets have, at least in my testing been quite inaccurate
thanks for your reply. tried yours dump. compared with mine and changed get from yours. some of pskeys brokes module. the same thing happened with another dump. need to find somewhere pskeys description to not to act like blind kitty :)
+Sergey Sereda you can try the configurator tool, that has 'normal names' for all the settings; however it always broke my unit, so, be careful

Hello. I really like your videos about programming CSR 8645 chips. I follow your steps, but unfortunately I am not able to get my chip working with BlueSuite app. I bought three CSR 8645 modules, but neither of them can communicate with the BlueSuite (I found 2.5.0 version only). Always I get an error, Can't read the chip type. Maybe you had similar problem?
Mmm, so - firstly, download the version I linked and see if it's perhaps newer
Are you using the same programer as I am ?
The problem is, that I can't download newer version. CSR support page says that I do not have the necessary privileges to view this category. (imgur.com/a/xlJbS7e). So version 2.5 is the only I could find somewhere on the web.
I use the same programmer, but with different pinout (bit.ly/2Le4QcO). I am sure I connected the pins correctly.
I have dropbox links though
Darieee oh I didn’t see dropbox link! Thank you. I’ll install this one and let you know if it works
So I installed the version 2.6.6 and still the same issue. Error detecting chip type (Read failed on USB-SPI). Any other suggestions? I tried different OS, different BT module already.
I don't have a 10K resistor. Can I still configure my csr8645?
I have a different one where all pins have holes, but some can be used.
also its not on ebay no more.
+MegaSpotman you probably should try going for some resistor; 1K around ? Some people did say they just connect the + directly - I never had the balls to do it, let me know if you go ahead - wether it worked or not
Darieee
I didn't know that.
Thanks for the quick reply and help.
did it work without the resistor? have anything hookedup expect the spi_en to plus
Tobias Link
I haven't tried without cuz I found some in a discarded portable stereo and not hooking up the spi_en didn't allow me to connect to the PSTool program
in case it does work - do let us know I'm also quite eager to find out xD
I have the csr 8635 will it still work?
Yes!
All the software that works with the CSR8645 also supports the CSR8635 and CSR8630
Thanks! I had to solder some wires. It worked tho, thanks!
welcome!
can this work for csr8635 on a Sanwu amp board?
Sure can !
Darieee
Thanks for the quick reply.
Thats awesome but does it turn on when enabling SPI_EN or SPI_PCM because mine won’t when connected to 3.3v nor 1.8v and powering it from the Sanwu Amp board.
I remember it worked for my 50w+50w, now I’m using 25w+25w.
Oh yeah the amp is called TDA7492P.
It really should - pulling the SPI_EN pin high simply switches the SPI pin to actually being the SPI bus instead of digital audio out
Darieee
Maybe i have to power it from the usb-spi.
I once powered my csr8645 on a breakout board by battery, but not the usb-spi, and I think it worked.
I’m gonna try that and if it works I’m gonna try to power it from the usb-spi and dc plug.
Is it a good idea to use two power sources?
Not really .. you should be able to power the bt board from the amp, and have it work, just don't connect the 3v3 of the programmer; only connect GND and a 10K resistor from the amp's supply for the bt module to SPI_EN
Okay renaming it worked but the parameter did not connect.
I tried DSP> Connection> USB SPI 51052
then ot the algorithm error.
sorry I didn't put this in your equaliser vid.
Soo, were you playing music while you were trying to set the equaliser ?
Darieee
sorry for the late reply
I wasn't playing music while changing the EQ cuz the module won't play loud enough for me to hear on speakers and the tda7492p won't play unless there is power to the amp and module.
I didn't want to damage it, but I have to hook up an aux to the Lp, Rp and Ln or Rn to plug in either headphones or other speakers.
I haven't done that yet but I guess I'll try after work.
+MegaSpotman you don’t have to have anything connected to anything on the audio side, the amp can stay powered off - just have the csr chip connected and powered to/by the programmer, and hit play: check the video though, I’m pretty sure I did mention all of this there

There, you'll have Restore Factory Defaults in one of the buttons above
how to change the PIN code?
I have no idea what you're talking about ?
Hello, Darieee,
First, thank you for the reply.
By PIN code I am referring to the parring password between the module and for example phone, so this way others don't pair with it. I looked in between the options, could not find it, therefore just decided to ask before I dedicate hours into it.
Thank you for your time. :)
No worries !
So, does your HAVE a pin code ? I've actually never seen one with it enabled ... in any case, the place where such a setting would be is in the ConfigTool
Check my "Disabling Microphone on the CSR8645" video, there I showcase how to run that program - although, from memory ... there wasn't any option for a pin
Salut Dariee, mi-am cumparat si eu tot ce trebuie ca sa programez un modul CSR8645, dar imi da eroare blue suite ca nu-l poate identifica.

And again I'm not 100% sure
So I found out I was using 100 instead of 10k resistors also it got ruined I’m gonna order a new one

Alright - sorry for the late reply - this one went into the spam folder; is that the CSR8645 or the 8635 or something else ?
Darieee
Its a csr8635 on a tda7492p.
I added the pins and a 10k resistor (which I found in a broken portable stereo) for the csr config tool.
Darieee
also i tried searching up on how the power supply works when using the config tool while its mounted on the amplifier and didn't find anything helpful so far.
I don't think I fully understand your power-supply question, but regarding powering the CSR8635 while it's being programmed, it'll have power from the programmer and it is NOT ADVISED to power up your amp during this process.
I've added two pinouts to the description of this video which should be all you need to get programming; connect MISO MOSI CSB CLK to the programmer, VBAT to 3v3 and GND to GND (the programmer has more grounds, all are the same - check if your csr8635 module has all grounds tied together, if not, just use the one on the lower right) AND also SPI_EN/SPI_PCM via the 10K resistor to 3v3
Let me know how it turned out (also, how good is the tda7492p amp ??)
Darieee
the tda7492p is pretty good.
so far I've tested up to three pairs of speakers and one of them is those wooden box type but not big and its pretty loud.
i can't test it now cuz its 8:24am.
