Thanks ! I've added it to the expanded view and reviewed it.
Flawless !

Me neither :-(

I can compare it against the "internal" data sheet.

I think it's this one:

Hmm no, the one we have (CON7601) has different connections.

The antenna is the same as for BT, but the symbol we have there doesn't
