Sometimes it happens that my bluetooth mouse gets disconnected from my laptop. Switching off/on the mouse doesn't help. Switching off/on my laptop bluetooth doesn't help either. Not even systemctl restart bluetooth.service helps.

But if I close my laptop lid to put in sleep and reopen it after a few seconds the connection with the bt mouse is re-established and all works fine then.

Also a reboot doesn't help. I have to power off / on the laptop

EDIT: As requested, here is some debug info:

$ systemctl status bluetooth.service

Please consider that the Address already in use occurred several hours before the bt mouse issue

Output of journalctl -xe is quite long.... https://pastebin.com/gViN5Tqp

  • Have you find the culprit? Do you have USB 3.0 devices plugged to your laptop when this happens?

I think the easiest thing is to use bluetoothctl to simply switch the bluetooth controller itself on and off.

echo -e 'show\npower off\npower on\nquit' | bluetoothctl

Try this: sudo rfkill block bluetooth && sleep 0.1 && sudo rfkill unblock bluetooth;

Try to unload/load (modprobe) Bluetooth modules.

  • well, this worked for me. all wireless communications were unblocked by rfkill, even restarting bluetooth service didn't fix it. but unloading and loading btusb module did the magic, I'm not sure what was the problem, couldn't see any error in journal. but definitely the trick was to reload its module. still can't confirm this is a permanent fix.
