Verify interesting discovery!
I don't recall there being an option with the M6.
@wolcano have you been pairing with 'Smartphone' so far?

This may suggest we could simplify the RP support by only using the 'Remote' pairing?

Looking further at this, the 'Remote' services are what are used by https://github.com/ArthurFDLR/BR-M5/tree/master/lib/CanonBLERemote.

This now #29.
