I've been trying out the bluetooth features on my Pi3 running the Krypton beta lately and encountered some issues I haven't managed to fix yet.
First time I tried the bluetooth functionality, everything worked fine with my iPod 4 Touch, I was able to connect and to stream music to OSMC, it also displayed track info. When I tried to connect with my android phone, OSMC did show up, but only as a bluetooth device, not a bluetooth speaker. I was able to pair the devices, but couldn't connect them, neither stream music.
For other reasons I had to reinstall OSMC on my RasPi, after the reinstall I was suddenly able to pair and connect both my iPod and phone just fine. OSMC showed up as a bluetooth speaker and connection was established quite fast. But when I played music on any of my devices, OSMC didn't do anything. No loading, no track info, no playback, no audio. In bluetooth settings it said that the device was connected properly, but that was it.
First installation: iPod can pair, connect and stream without problems, phone can only pair
Second installation: Both devices can pair and connect, but neither of them can stream.
Any ideas on this?
