This looks like the BLE version (Bluetooth LE, aka 4.0), rather than rfcomm.

The above looks very much like a GATT thing, not a rfcomm thing. Which
is how the BLE thing works, but we don't support it under Subsurface
yet.

Yeah, there's no traditional RFCOMM there at all, afaik. So you
apparently have one of the newer Perdix ones that have new bluetooth.
