Bluetooth not working

For some reason bluetooth isnt working for me, It worked on Ubuntu no problem but not under Arch.

When typing bluetoothctl power on it just prints No default controller available. I tried all the fixed from the wiki and various websited but no luck.

journalctl -b | grep Bluetooth gives me this result:

trying to unload and reload the kernel with rmmod btusb / modprobe btusb gives me this result in journalctl:

Its a bit different but I have no idea if its any helpfull.

Also I currently use the bluez-utils-compact from the AUR since it was mentioned as a possible fix, but when with the bluez-utils package it doesnt work.

Now I ran out of options so I'm asking here for help

Re: Bluetooth not working

try stopping the bluetooth service and blocking the bluetooth controller with rfkill, then unblock it again and start bluetooth service and then power on.

sudo systemctl stop bluetooth
sudo rfkill block bluetooth
sudo rfkill unblock bluetooth
sudo systemctl start bluetooth
bluetoothctl power on

if that doesnt work what is the output of:

bluetoothctl list

and

bluetoothctl show

and i guess

rfkill

Re: Bluetooth not working

hmm you might have to try different kernel versions and/or bluez versions till you find the culprit
