How to use simultaneously A2D, AVRC and SPP in a ESP32?

[riccardo.brue]

Hi, I have the task to create a little device which is capable to send/receive data through SPP and then to simultaneously stream audio data through A2C/AVRC bluetooth protocols. Is that possible? I was looking to classic bluetooth examples in the repository, but I don't know how to "merge" these two bluetooth stacks in order to run simultaneously.

Another future job should be to use also the GATT stack; will this be possible while running the other three stacks? If yes, could you please provide some initialisation codes? I will appreaciate a lot, thank you.

Hi, did you get anywhere with this? I have a similar task - to connect a2dp as source and also connect spp to a second device.
Thanks,

Yes
Check out my https://github.com/jorgenkraghjakobsen/merus_bt.git
I connect from android SPP client to control volume, dsp flow etc and monitor amplifier state
Integrates very well.
