Bluetooth sink and source at the same time #286

I am working on a spectrum analyzer project with the esp32 and want to stream audio to the esp32 from a phone then do a fft on the esp32. At the same time the esp32 has to stream the same audio to a bluetooth speaker. |

No, that will not work. But you can implement your own bluetooth speaker with the A2DP sink and do the FFT there. |

2x ESP32s linked together via i2s. ESP32 #1 is your sink. ESP32 #2 is your source. Audio data is passed from sink to source via i2s link between the 2 ESP32s. I am currently doing this exactly thing in my project. |

Another option would be to simply get the audio via a microphone..
