Thats a nice add on. Only thing I would suggest is to use a little liquid flux when tinning the board connections and soldering the SMA to the board. Will allow for a better, well soldered connection. That will help the RF path significantly... no dirty joints and better flow.
This is great! I hope to find a SMA connector to desolder from an old router...that would be perfect! I have some black hot glue, that should make the final result very good!
I'm 2 for 3 attempts at this... The first two increase range a lot. However, the board is really unstable. It panics and reboots after a few seconds. I'm sure I'm screwing it up somehow...
Need to cut the path to internal antenna, or completly remove intenal antenna path . The output of radio freq will totally going through external antenna.
@@manfredhackstock418 wifi and bluetooth share the same hardware, if you modify one in this way, you modify the other. see esp32.com/viewtopic.php?t=982
Actually yes, WiFi and Bluetooth (and ESP-NOW for that matter) share the same RF I/O hardware. There is no other antenna for it to use. They all operate in the same frequency band so there's no reason _not_ to share that hardware. The only ESP32 board I know of that has another radio is the one with cellular connectivity and even then it's actually a separate chip on the PCB providing that functionality, not the ESP32 itself.
Theres a few things I want others to know if they watch this. 1) NEVER TURN your devices on without an antenna attached! This will burn up the radio... 2) The soldering work in this video shows exactly how not to solder. When dealing with radios, its VERY important to take care with your solder. Too much is a bad thing, wrong tips is also a bad thing, and of course too little is bad. In this case, the author uses too much solder while tinning and then has to apply a lot of heat to get the solder to spread out. This will cause problems that you will not be able to figure out. Low signal, dropped packets. With that said, good video on how to add an antenna to an ESP32.
I know that it's an old comment, but still... one reason would be if someone will use an antenna on the end of an small extension coax. Those have a shield and that must be grounded to avoid signal scattering. Plus... it adds stability to the connector.
Great video. If I want to solder a cable rather than the SMA socket directly to the board, should I solder the center core to one end and the cable shielding to a different end of the embedded antenna ? Tks!! Here is the link to the board: ua-cam.com/video/zGsMKEwCqkU/v-deo.html
Nah, for these odd hobby purposes just use 60/40 flux solder. Perfect video, excellent solder work. Use of hotglue to fix it mechanically is of course highly recommended.
Watched the hole tutorial then saw him turn on a transmitter with no antenna all credibility down the drain right there 😅 stop making tutorials if you don't know what yur doing

Music was very majestic thank you
you held the hot SMA with fingers while soldering???
Good job. Thank you for the instruction. I don't understand using Blink to get your SSID & signal strength measurement.
it's just the file name, the code gets the network infos
Thanks, very useful.
Wooow, my flac's without breaks :) awesome.
Hey thanks! I've done the same. It increased the range at least twice for me.
Hi Dmitry 👏🏻😇
How far did you measure?
Within one apartment. Good coverage.
@@dmitrymenshikov3387 how can we try this on esp8266
not sure what you mean.
You can use this video as a guide for Bluetooth and wifi antennas.
Very cool,thank you

Cool, will try it
Thanks ... Nice to have proof before I hack mine up too.
Wonderfull, Thanks
Does it work with a cantenna? I loved the music!

melo caramelo!! me ayudo muchisimo gracias...
Si te funcionó sin problema amigo ?
very nice..
So cool
Jajaja!!! Justo estaba pensando en eso con la antena de un viejo modem.

Can I do this for esp8266
Nice
Someone measured reflected impedance and noise with this soldering hack?
How exactly would you go about that?
HI,
is the same antenna used for bluetooth?
It would be interesting to see if the scan range can be improved as well.
Hi, it is WiFi only

@@sleepyboi6226 this device already have antenna 😐 he is extending the antenna. So the antenna is already there . For ur kind information
So this can work but you need do it good for work?
why you solder two to wires? cut-off pcb antenna and solder one wire only

Try this on esp 8266
Could this be done on the ESP8266?
yes
@@-vermin- I assume you have done it to a Esp8266. Is the polarity the same?
@@eclecticlife it's kinda mirrored.. mass is still on the outside. Just did it. Works fine :)

Yes.
Since a ESP32 is soooo expensive.. lets take good care on the amount of solder being used hahahahhaha shall we..
Senin benim için expensive kardeşim, onlar için bedava. Ekmek parası değil.
ESP32 is NOT expensive. Development boards $3-4 each
3$ dude not expensive
1$in Iraq.
do you even FLUX, bruh? This was painful to watch.
