[Bug]: i can't use a A2DP

ErickRBTK commented 3 weeks ago

What happened?

A bug happened! Hello, someone has tried to enable A2DP to send audio (if possible to the gamepad), simultaneously with the gamepad to send it to wireless headphones.

use the example BT_MUSIC_SENDER_WRITE from the ESP32-A2DP library I tried, but I get an error to compile

Bluepad32 uses BTstack as the Bluetooth stack, and not the one from esp-idf. So, if you want to use A2DP, you have to use the BTstack API for that.

Search in the BTstack examples, there might be one: https://github.com/bluekitchen/btstack/tree/master/example

Thank you very much, this gives me a clue to see if I can integrate it into my project or look for another alternative.
