Public bug reported:
After turning bluetooth off (unexpectedly hangs, bug report already present),
blueman cannot restart bluetooth adapters. Opening in terminal blueman-applet
and trying again, but this produced no helpful errors, so i started
blueman-adapters since this can only be opened when bluetooth adapters are
started, this produced more helpful output:
pi@raspberrypi:~ $ blueman-adapters

IOError: [Errno 5] Input/output error
If i run ¨$ sudo /etc/init.d/bluetooth start¨ you will notice there exists no
problem with the bluetooth service:
pi@raspberrypi:~ $ sudo /etc/init.d/bluetooth start
[ ok ] Starting bluetooth (via systemctl): bluetooth.service.
I have tried stopping and starting the service both before and after invoking
blueman-applet or bluman-adapters. The result is always the same, bluetooth
service reports ¨ok", blueman-applet plays ¨Turn Bluetooth On¨,and no bluetooth
devices work. In fact, attempting to use a bluetooth device still causes the
following error:
Failed to connect to device -
GDBus.Error:org.bluez.Error.NotReady:
Resource Not Ready. Try to connect again.
