connect and send audio data to a2dp sink

Postby ppisljar » Sun May 21, 2017 7:22 pm

I saw https://dl.espressif.com/doc/esp-idf/la ... _bd_addr_t and am wondering if this can be used to connect to a2dp sink (bluetooth speaker) and send audio data to it ?

There is an SBC encoder in the SDK, so its probably there for a reason. Let me know when you find out how.

here you go on with a random sequence
