I have a Dell XPS 13 with Fedora 29 and a bluetooth headset that connects flawlessly with my other devices (e.g. phone). In Fedora, it shows up in the list of devices of the bluetooth module, but it is disconnected. When I click on it, a windows pops up, but the "Connect" switch is disable, and the text below the switch reports the device as unpaired. Using bluetoothctl in a terminal, the "pair" command exits with the following message:
Failed to pair: org.bluez.Error.ConnectionAttemptFailed
I have pulseaudio-bluetooth-module installed. Any idea on how to get the headset working?
