Pipeline and A2DP Sink Example

Postby learningWithESP » Thu Aug 06, 2020 3:32 pm

Hello. I am completely new to ESP 32 and hoping to eventually develop my own applications with an ESP32.
I am currently running the pipeline_a2dp_sink_and_hfp unmodified. I use bluetooth on my phone to connect to it. I expected to be able to play media audio (i.e. youtube, music player apps etc) as well as use the speakers to play phone calls.

I am using a Lyrat v4.3 board and have no problems playing media audio, however, when I am in normal cellular phone calls and force the phone to output to the ESP over bluetooth, I hear no sound from either ends of the call.

Have I miss understood how the example works? Is it possible to use the Lyrat as an output for normal phone calls?

I had to check out an older version of esp-adf to get this to work.

Code: Select all

cd ~/esp/esp-adf
git checkout v2.0
git submodule update --recursive
(May require some additional git clean -ffd depending on which version you had checked out)

Exit the terminal (to clear any previous exports/python virtualenvs that were using a newer version of the toolchain)

Reinstall idf's tools using the submodule

Code: Select all

cd esp-idf
./install.sh
. export.sh
Hope this helps
