puck on windows "paired" but not "connected" (or connected but not HID)

In Windows you'd expect that the device goes back to 'Paired' from 'Connected' if Windows doesn't find a reason to maintain a connection - which would be the case if it didn't think your device was a HID device.

Just as a quick sanity check, what happens if you just do:

var kb = require("ble_hid_keyboard");
NRF.setServices(undefined, { hid : kb.report });

without any of the other services?

I might be that if windows sees the 180A device information service but it isn't in the format it expects, it just drops the connection...
