SP32 only offers a microphone profile as a Bluetooth device

[eric-r-moore]

Sorry, I'm probably new to ESP and am currently looking for a demo that can use the ESP32 as a microphone.

I was thinking that the HFP profile can transmit the sound of the phone and provide its own microphone to send to the phone. I want the phone to use its own speakers, and the ESP32 only offers microphones, is that possible?

Going one step further, I wanted the microphone's audio quality to be up to A2DP's stereo standard.

Any suggestions? Thank you very much
