Setting up auto connection
To make your headset auto connect you need to enable PulseAudio’s switch-on-connect module. Do this by adding the following lines to /etc/pulse/default.pa :
/etc/pulse/default.pa
# automatically switch to newly-connected devices
load-module module-switch-on-connect
Now make bluetoothctl trust your Bluetooth headset by running trust 00:1D:43:6D:03:26 inside the bluetoothctl console to prevent errors similar to:
bluetoothd[487]: Authentication attempt without agent bluetoothd[487]: Access denied: org.bluez.Error.Rejected
[bluetooth]# trust 00:1D:43:6D:03:26
By default, your Bluetooth adapter will not power on after a reboot. The former method by using hciconfig hci0 up is deprecated, see the release note. Now you just need to add the line AutoEnable=true in /etc/bluetooth/main.conf at the bottom in the [Policy] section:
/etc/bluetooth/main.conf
[Policy]
AutoEnable=true
