Support For Bluetooth A2DP and HFP At The Same Time
Support For Bluetooth A2DP and HFP At The Same Time
Is it possible to have both an A2DP and a HFP connection to a phone at the same time from the ESP32? I currently have firmware written that uses A2DP to stream audio to a speaker. I now need to be able to periodically send the speaker's battery level information back to the phone while audio is streaming. I believe the only way of doing this with BT classic using the HFP connection. This is the only feature that I require from the HFP. I don't want to stream any audio using HFP as the A2DP has much better sounding audio.

To send battery level you can probably use AVRC command.
