Closed sebastienroy closed 4 years ago

It would be nice if the radio could behave as a bluetooth device when the it is switched off. So that, it could be used to listen to podcasts for instance.

Interesting resources on bluetooth can be found there : https://www.sigmdel.ca/michel/ha/rpi/bluetooth_02_fr.html And following : https://www.sigmdel.ca/michel/ha/rpi/bluetooth_02_fr.html https://gist.github.com/mill1000/74c7473ee3b4a5b13f6325e9994ff84c

First, following https://www.sigmdel.ca/michel/ha/rpi/bluetooth_02_fr.html and https://scribles.net/updating-bluez-on-raspberry-pi-5-43-to-5-48/ I've updated the bluez library to 5.54 The initial version was 5.50

This article is more recent: https://scribles.net/streaming-bluetooth-audio-from-phone-to-raspberry-pi-using-alsa/ And the result is OK! I succeed in playing music on the raspberry from the phone. I have now to be able to modify the volume and to integrate the command lines in the radio code.

In order to send commands to the bluetoothctl service:

echo -e "discoverable on" | bluetoothctl
