Hi Luiz,

Yes it will repeat the scan every few seconds.

I paired the device in the Gnome applet.  In the bluetoothctl I could
see the pair and trust messages like so:

[NEW] Device C5:8C:97:E6:9C:81 Arc Touch Mouse SE
[CHG] Device C5:8C:97:E6:9C:81 Connected: yes
[CHG] Device C5:8C:97:E6:9C:81 UUIDs:

Thanks,
