Two gotchas: protected 18650s sometimes don't fit, and there's 2 versions of that display with different pinout orders. I think the ground and Vcc are swapped on the incorrect one so it can't be soldered directly. If I have enough time (which I never seem to) I will try and make a video to supplement @Meshtastics fantastic videos going through some of the confusions with channels, total flood routing, and the terminology (e.g. "modules").
Thanks for this quick tutorial. Bought my ttgo t beam from lilygo on aliexpress. It came with the firmware pre-installed, but the middle button and the gps weren't working until I reflashed the stock firmware manually. And for the record, the soldering WAS a pain in the ass 😅
That sucks that you had to reflash it, I'm guessing theyve made some pretty big updates lately. I actually just found 2 t-beams I ordered and forgot about (I have problems lol) and get to join in on the soldering fun! What solder did you use? Lead is bad to eat but it is amazing to solder with! Thanks for watching! 😀
@@diyrenewableenergyelectron4996 It was some cheapo "lead-free rosin core electrical solder" I got in a kit with the soldering iron. The solder liked sticking to the iron way more than any of the pins though. Had to scrape the melted solder on with a knife. In hindsight, I think I was supposed to "tin the tip" of the iron in the first place... Came out pretty janky, but it works! 👌
I've used the lead-free stuff and it usually has a higher melting point than the solder with lead. I soldered a battery together a while back and almost threw the iron through a wall. It was terrible. I'm a fan of rosin core solder with lead. Tinning the tip definitely helps! I like to heat the tip, add a bunch of solder then wipe the tip on a damp paper towel. It leaves a nice coating of solder without having giant blobs that want to make a huge mess. Glad to hear you got it up and running!
Right after you got the first video up i bought a pair of lora32 non gps. I got them programmed and ready to go 1 will be up in a mountain as a relay repeater and the second on my house and soon 1 more on my mobile.
@@diyrenewableenergyelectron4996 I'm using regular firmware with the add on of a parallax flip 32123 data repeater module. There is a guy here in yt who made one I'm just going to coppy him lol
@@diyrenewableenergyelectron4996 is just a data repeater. It gets the data. From the lora32 /message. And 10 milliseconds later sends the data. Back out.
Thanks for the video. I was able to flash my tbeam but it will still not connect to my iphone meshtastic app. Just times out after 10 attempts so any info on that would be appreciated. Thanks.
Unfortunately I haven’t tried anything yet with either Tbeams or the iPhone app. I would recommend posting on the meshtastic forum to see if they can help diagnose the issue. Thanks for watching!
trying to double click the middle button to set pin to 123456 but it still wont pair inside meshtastic, oled is not working if it comes up in ble list does that mean firmwere is on the t-beam or does that list regardless?
You can try reflashing the t-beam and see if it works but I haven’t flashed a T-beam yet to know the exact process. It should be the same as the boards I showed but you just select the t-beam firmware. Let me know if you get it working!
I’m not sure. I just follow the instructions on their website because I’m not very adept on the firmware flashing side of things. Lol thanks for watching!
Yes and yes. I think you have to choose the board with bluetooth, and the app will use the phones GPS. There is also a "T-beam" that has GPS into the board.
I think you would need a different messaging system. I don’t see why the LoRa modules wouldn’t work, but I can’t think of an off-the-shelf software that would work the way you described. Hopefully someone else can chime in with an option for you! Thanks for watching!
How do I change the channel, I have heltech v2.1 and ttgo tbeam v1.2 connected to my phone no problem but messages aren't coming through when paired with my phone and my wife paired with 1
@@diyrenewableenergyelectron4996 that's actually how I flashed it downloaded a zip file loaded with every model siphed thru and loaded my ttgo and heltech Lora 32 with respective firmware
By default if you don't change the channel any radios that come in range will automatically connect. So if you just flash the firmware onto the radios like I did in the video it is sort of like a global channel. Thanks for watching!
It doesn’t turn on or doesn’t wake up after going to sleep? Usually once a message is sent and the radio sees an incoming or outgoing message it will wake up. Thanks for watching!
Such a great tutorial! Thank you for putting this together and sharing with your audience.
I appreciate the kind words. It’s quite the brilliant radio setup you devised 😉
@@diyrenewableenergyelectron4996 But of course! This is all about having fun. :)

how did you reflash it, im having the same issue from ali-express lylgo t beam , where you get the firmware and how did you re flash it, what app?
Right after you got the first video up i bought a pair of lora32 non gps. I got them programmed and ready to go 1 will be up in a mountain as a relay repeater and the second on my house and soon 1 more on my mobile.
Yes! I love it. Did you go with the standard lora firmware for the one on the mountain or did you try the "relay" firmware? Thanks for watching!

Ignorance here, what benefit does the parallax flip provide?

Cool! Sounds like a fun project! You'll have to report back how the range/reception works out with the setup.

@@diyrenewableenergyelectron4996 thanks
i am experiencing the same issue
That was very helpful and inspiring, as a licensed ham I still have yet to build a Lora unit but very soon that's going to change.
These little units are great for hobby use. I'm glad you enjoyed the video, thanks for watching!
Thank you i was trying to find out why the pico had no display. I wish they could name the files with a more detail on what type of .bin to use.
Great video thx.
Thanks for watching!

I'm getting a Lora32 soon. I was expecting to use the webflasher , doesn't that work without any other things ,apart from USB driver?
I’m not sure. I just follow the instructions on their website because I’m not very adept on the firmware flashing side of things. Lol thanks for watching!
does the ttgo lora32 board have bluetooth? Also since it doesnt have gps, is it able to share your phones gps?
Yes and yes. I think you have to choose the board with bluetooth, and the app will use the phones GPS. There is also a "T-beam" that has GPS into the board.
Is there a program button on this one? I have this model and I the one button only resets the unit.
I don’t think so. All of my programming was done through the app or computer. My buttons just cycle through info and reset the device.
Instead of using phones/apps, it there a way to use this to make sensors work across a distance and then send to my mqtt on my raspberry pi?

What if I am not in a US and my country is not listed. Then which one should I select?
Did you check the full list on meshtastic.org? I'm not really sure which you should choose if your country isn't listed, though. Thanks for watching!

Nice! Range test video coming soon(ish) lol
is, there now a global channel, where all can get messages ... ? if you come in range ...

Anyone know why the TTGO lora32 v2 would not show up in the serial port list? I'm not able to flash the board...
Never mind. I found that the CP210x chip needs drivers from www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
Glad it got squared away for you. Thanks for watching!
ttgo t beam cant wake up with battery...any idea
It doesn’t turn on or doesn’t wake up after going to sleep? Usually once a message is sent and the radio sees an incoming or outgoing message it will wake up. Thanks for watching!
Sir please help me ttgo t beam firmware flash and upgrade
I’m working on this myself right now. If you haven’t flashed your firmware I am planning to post a video soon.
