ESP32 Development Board for FM broadcasting. Complete DA Audio processing. The example/default Arduino firmware works as a Bluetooth Speaker (A2DP Sink). The code builds with the newest ESP32 Arduino Release.
We have discovered a bug that prevents using other sampling frequencies than 44100Hz (there is only silence).
That means: Streaming music from Android phone works well in default settings. Computers (Win) use 48kHz instead so you either have to manually switch to 44.1kHz Fs or wait for the fix to came up.
