bluetoothctl list = empty
Is my BT Stick not compatible?Found a "Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)" Stick under my couch! Is working now, YEAH!
Send with much love & Android.
I had the same issue, tried the suggested workarounds - no success,
I tried the following: setting the "Keep Audio Alive" to "10 minutes" in "System"--> "Settings" --> "Audio..." Don´t set it to "Always", doesn´t work, tried it.
Now I can listen for an extended period of time... still waiting for the drop out... fingers crossed.
Hope that helps, as this Pi 3 is a nice system and crappy bluetooth hardware would be very stupid.
