I pay 50$ (USA dolars) for writing a simple application (technology demonstrator) that will work on ESP32-LyraT 4.3 ADF 2.0 and IDF4.x required. I want connect Headphone in HFP Hands-Free Unit mode (Speaker + Microphone) to ESP32-LyraT 4.3 working in HFP Hands-Free Audio Gateway mode and transmit 2 ...

I really need audio path working on ESP32-LyraT 4.3: Microphone -> Audiocodec (i2s) -> ESP32 (HFP AP function) -> Bluetoth Headphone Speaker and Speaker <- Audiocodec (i2s) <- ESP32 (HFP AP function) ...
