Add Bluetooth headphones

[Hack228pro]

Hello, I came up with an idea if there is a controller on the board esp32 Why can't we output sound to wireless headphones?

Not possible:

1. Bluetooth LE installed in ESP32-S3 doesn't support audio profile
2. The receiver audio output is not wired to the CPU

if the esp32 would support audio .. adding a few jumper wires would be an easy task ...
be it bluetooth headphones or speakers

Hi @DG9BFC !
I personally did what you're saying. I'll post my experiences soon. The only way to do it is via webstream, as there is no A2DP (Bluetooth Audio Profile) available for the ESP32S3, as the chip doesn't support Bluetooth Classic, only the newest generation BLE for wich there's no mainstream audio profile nor devices like speakers yet.

Also, to do it via webstream and not adding any chipset, only with jumper wires, the quality is very very low as the ADC on the ESP32 is not really suitable for audio purposes. Only low sample rate and high noise, perhaps only suitable for VOICE or CW.

You neeed to:

1- Cut a trace
2- Solder 2 jumper wires

Stay tuned for my coming post in Discussions.

Cheers!
