### [BTHID library](BTHID.cpp)
The [Bluetooth HID library](BTHID.cpp) allows you to connect HID devices via Bluetooth to the USB Host Shield.
Currently HID mice and keyboards are supported.
It uses the standard Boot protocol by default, but it is also able to use the Report protocol as well. You would simply have to call ```setProtocolMode()``` and then parse ```HID_RPT_PROTOCOL``` as an argument. You will then have to modify the parser for your device. See the example: <https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/BTHID/BTHID.ino> for more information.
