support for iOS Home button in ble_hid_controls.js module

I am playing now on making it discoverable as a keyboard, maybe that's why iOS is ignoring it.

Have you had any luck pairing it as a normal BLE Keyboard using the example code? It might help to narrow down any issues. I'm pretty sure I've had that going on iOS just fine.

Come to think of it, are there any iOS debug logs you can get at? They might give you some useful info?
