Debugging HID/Keyboard with serial to another Puck?

Thanks, I'll try that. I do want to get disconnect working in some way, as I want it to actively disconnect from the iPad so the iPad doesn't keep thinking it's got an external keyboard; unless I can figure out how to get it to realise that it's not really a keyboard, which I imagine will be nasty -- it's nasty to do in Bluetooth Classic, IIRC.

So, do you think keeping track of the HID connection (the BluetoothRemoteGATTServer via the Promise, presumably?) and issuing a server.disconnect() is the way to go?

(EDIT: Oh, hang on... that won't work... these connections are initiated by the iPad; there's no connect call going on, and we're the server, so there's no BluetoothRemoteGATTServer object. Hmm. If acting as a server rather than a client, is there a way to selectively disconnect a connection, or is it just a case of NRF.disconnect() and let the UART service and anything else be damned? )
