I installed Ubuntu 22.04 and the Bluetooth was working fine. I turned off the Bluetooth and could not turn it back on.
I did some research and found some calls to turn it back on:
sudo rfkill unblock all
sudo hciconfig hci0 down
sudo rmmod btusb
sudo modprobe btusb
sudo hciconfig hci0 up
Now, I can turn it on and off as I please but It is now not connecting to any device. It would connect for a brief second and then disconnect. Can't find anything from research. Anyone can help with this ?
Also, Whenever I boot up windows, the bluetooth works perfectly fine on windows. So it's not an hardware issue.
I ran the command: bluetoothctl
As you see in the screenshot, it is cycling through connecting to the device and disconnecting.
I ran sudo journalctl -b 0 | grep blue
sudo journalctl -b 0
page through the logs, looking for bluetooth entries
