I get an error message when I click "Set Dongle Address", what can I do? (Linux+bluetooth)
Some bt dongles are not compatible. Try another one.
How can I set my old bdaddr back? (Linux+bluetooth)
Start a terminal: Click on the Ubuntu Dash, type "terminal" in the search bar, and click on the terminal icon.
Then type:
sudo bdaddr -i hciX YY:YY:YY:YY:YY:YY
Replace X with the dongle index (0, 1, 2...), and YY:YY:YY:YY:YY:YY with the bdaddr to set. If you have multiple dongles and if you are not sure about the dongle index, type bdaddr -i hciX to see the current bdaddr of the dongle with index = X.
