are they any errors in journal for the lomiri system settings service?
Nothing:
phablet@ubuntu-phablet:~$ sudo journalctl -u lomiri-system-settings
-- No entries --
well, there is no such thing as a lomiri-system-settings systemd service so it's to expect that you will find nothing in the systemd journal under this item.
I'd say that if you can connect to your UT phone with ssh (it's really more to my liking that the UT terminal to do debugging) you could start bluetoothctl, take a look at the result of 'show' (your controller should be powered, discoverable and pairable), 'device', and if you see your device 'info <bluetooth address>' - if not, see what is displayed when you disable/enable pairing on your Bluetooth device.
