Good day,
I have previously already complained that my bluetooth was not working. It happens quite regularly, but I managed to fix it by reinstalling “bluetooth-*” related packages or with a following commands.
Or with following commands:
# rmmod btusb
# rmmod btintel
# systemctl stop bluetooth.service
# modprobe btintel
# modprobe btusb
# systemctl start bluetooth.service
Unfortunately, bluetooth is not working again and non of those workaround are working for me anymore.
I would appreciate an advice. I found couple of places that seems strange.
Why is there a “no default controller” here?
bluetoothctl ✔
[bluetooth]# Agent registered
[bluetooth]# power on
No default controller available
[bluetooth]#
Or why I can find a device id here?
sudo dmesg | grep -i bluetooth
