Title:
Bluetooth devices don't reconnect after sleep.
Status in bluez package in Ubuntu:
Confirmed
Bug description:
Bluetooth devices don't reconnect after sleep, or something along
those lines.
I have experienced this with a BT audio receiver and BT Keyboard. One
way to repro is to switch BT pairing on multi-pairing keyboard, then
switch back to Ubuntu. The BT connection state will be very confused,
keyboard will not work.
Another way to repro is to get a bluetooth audio receiver, pair it.
Let the BT device (or PC?) sleep... now wake up the system. The audio
will not play. BT UI slider says disconnected. If you click the
slider it will go back to off. If you click it quickly >25 times, no
joke, it will reconnect and work.
FYI: Raspbian handles the keyboard fine, have not tested the audio.
