Yes, I just swapped to 2020-06 and it works fine with release 4.2

I installed ESP IDF with esp-idf-tools-setup-2.3.exe In eclipse 2020-12 I installed (Help > Add Software): CMake Editor 1.14.0 Espressif IDF Plugins for Eclipse 1.2.3.202010091505 from https://dl.espressif.com/dl/idf-eclipse-plugin/updates/latest/ When installing the tools I got some warnings at the...

After some reading I think the ADF won't solve anything because the problem is not audio, but in the bluetooth.
The more proper question I think is:

Can the ESP-32 be a central bluetooth device?

I tried to use the example a2dp_source in the IDF to connect to a BT speaker but it won't find it.
Am I missing something or do I have to use ESP-ADF?

Any quick pointers on how to modify the A2DP-SOURCE to:
- Just connect and keep it connected
- Use I2S as input

I just built the a2dp example and flashed it into the DevKit but it finds an error and resets.

E (572) I2S: /home/joan/esp/esp-idf/components/driver/i2s.c:838 (i2s_param_config):I2S communication format invalid.
E (572) I2S: I2S param configure error

I found somewhere it's 4.2, is that right?

All the question is the header

I would like to stream audio to the ESP-32 from a PC or phone. I suppose this is possible, is there any example application to base myself on? Also, is there any limitation in the audio formats?
