Bluetooth

We can use graphical tools to make our life easy by using one of the following tools:

  • blueman (with all its tools) and in particular blueman-manager
  • blueberry
  • gnome-bluetooth

Manual Configuration

Configuration via CLI Start the bluetooth.service systemd unit.

Now we can use the bluetoothctl command line utility to pair and connect. For troubleshooting and more detailed explanations of bluetoothctl see the Bluetooth article. Run:

bluetoothctl

to be greeted by its internal command prompt. Then enter:

[bluetooth]# power on
[bluetooth]# agent on
[bluetooth]# default-agent
[bluetooth]# scan on

Now make sure that your headset is in pairing mode. It should be discovered shortly. For example,

[NEW] Device 00:1D:43:6D:03:26 Lasmex LBT10 shows a device that calls itself "Lasmex LBT10" and has MAC address "00:1D:43:6D:03:26". We will now use that MAC address to initiate the pairing:

[bluetooth]# pair 00:1D:43:6D:03:26

After pairing, you also need to explicitly connect the device (every time?):

[bluetooth]# connect 00:1D:43:6D:03:26

If you are getting a connection error org.bluez.Error.Failed retry by killing existing PulseAudio daemon first:

pulseaudio -k
[bluetooth]# connect 00:1D:43:6D:03:26

If everything works correctly, you now have a separate output device in PulseAudio.

Note: The device may be off by default. Select its audio profile (OFF, A2DP, HFP) in the "Configuration" tab of pavucontrol. You can now redirect any audio through that device using the "Playback" and "Recording" tabs of pavucontrol.
