ESP32 audio source can't start media and transmit audio

Postby ypiotr » Tue May 26, 2020 8:16 am

Hi,

I have a problem with connecting with a2dp sink, which is a bluetooth speaker. I modified some code and the media don't want to start. The log shows, that the connection is established but then nothing happens. At the end my connection timeout mechanism gets called and the disconnect request is sent to ESP so it stops attempts to connect.

Here is my log of the situation:

Code: Select all

BT_AV: a2dp media ready checking ...[0m

What does it mean? How can I fix it so it starts the media like it did before?

Thanks for your help!
