Bluetooth Driver

Bluetooth is plain BlueZ, with nothing libretouch-specific about it. The controller is the WL1835's, and it does both Classic and Low Energy.

Start the service and enable it for subsequent boots:

systemctl enable --now bluetooth.service

Then use bluetoothctl as usual. Set the scan transport to bredr for Classic or le for Low Energy:

bluetoothctl
power on
menu scan
transport bredr
back
scan on

Stop with scan off when finished.
