I have some problems with a bluetooth speaker (Anker Soundcore 2).
Libreelec disconnects after some time playing (5min - 30min) automatically and did not connect back again.
It doesnt matter what kind of media was playing, mp3, video, live tv.
Only after a system reboot the connection is back again also automatically without need to connect manually.
The speaker itself works on a lot of different systems without problems so i think its the rasp with libreelec.
Maybe someone else has same problems and maybe a solution for it?
