WiFi errors attempting to use a BT Emitter #493

Closed rjshiffer closed 1 month ago

rjshiffer commented 1 month ago

Hi Wolle and others,

I'm unable to get the radio to operate correctly when the BT Emitter is attached. I've tried with both an ESP32 and ESP32-S3. I get numerous WiFi error messages and continuous re-boots. There seems to be a conflict between WiFi and the BT Emitter. I soldered the KCX_BT_Emitter to a PCB same as the one shown in a previous issue (see my picture). Only very, very, occasionally do I get the BT Emitter to connect to a remote speaker and then only for a few seconds.

Suspecting the Emitter/PCB soldering, etc., I checked with a multimeter to ensure proper connectivity with no solder bridges, etc. No problems are detected.

All my connections are as shown in the ESP32 and ESP32-S3 schematic drawings in the docs folder.

I'm at a loss as to my problem. Could you please give me a pointer as to where I could look next.

Thanks. Richard

(I hope I did not overwhelm you with the volume of serial monitor output.)

KCX-BT-Emitter

schreibfaul1 commented 1 month ago

BT and WiFi use the same frequency range. Where BT looks for a free channel before it transmits (frequency hopping). Nevertheless, influences can occur. Try to rotate the BT antenna 90° compared to the WiFi antenna, horizontally and vertically. And the distance between the two should be as large as possible. If it is not possible to shield the antennas from each other, try to wrap the BT module in an antistatic foil, image

You can simply put such a bag over the BT module for testing. The BT range will still be sufficient after that.

rjshiffer commented 1 month ago

Yes, that is what is happening. I placed the BT Emitter in a antistatic bag, and re-orientated it as you suggested and was able to get more consistent connections and the streams play but with "slow stream, dropouts are possible."

Realizing that the work room I was in had other BT/WiFi interference possibilities (fluorescent lights, wireless controllers, another MiniWebRadio running in background, etc.) I moved the radio to my normal living space and it works fine with only minimal, barely noticeable dropouts over a period of an hour.

That's for your help.
