I found some solutions to use raspberry as bluetooth client to play audio. For example, to play music from phone to raspberry via bluetooth.
But I didn’t find any solution to push audio from KODI to bluetooth speakers. It would be nice, if KODI could recognize bluetooth audio device automatically and start streaming music to bluetooth device. I would like to use USB dongle for bluetooth transmitter connected to raspberry so the raspberry can simultaneously play via bluetooth and audio output. Is ti possible?
Mod Edit: use this: [TESTING] Bluetooth audio streaming (A2DP)
