Can Bluetooth connection parameters be modified in ESP32 A2DP Sink Mode?

[litezxc]

Hello,

I am currently working with the ESP32 as a Bluetooth A2DP sink, outputting audio to an external DAC. I would like to know if it is possible to modify the Bluetooth connection parameters while the ESP32 is in this sink mode. Specifically, I am constrained to using a standard format of 44100 Hz, 16 bits, and 2 channels for audio output.

However, I have noticed that codec supports a sample rate of 48000 Hz. Is there a way to set this sample rate or other additional parameters such as bitrate, number of subbands, etc.?

Thank you for any insights you can provide!

You will need to check if it is supported by your A2DP source to change e.g. the rate

Please check the IDF documentation: to my knowledge there is no such thing...
