Source Files

• BTKeyboard.swift

  Creates a Bluetooth SDP service using SerialPortDictionary.plist and listens for incoming connections.

• KeyCodes.swift

  Converts virtual key codes (the number assigned to keys according NSEvent) to HID key codes (as specified in the USB specification).

• AppDelegate.swift

  Initializes BTKeyboard then uses CGEventTap to get keyboard events and send them to the connected Bluetooth device.

• SerialPortDictionary.plist

  A service record with a Human Interface Device Profile (HID). The HID profile describes a keyboard and the report used is outlined in HIDReportDescriptor.txt

• HIDReportDescriptor.txt

  The parsed HIDReportDescriptor outlines how the bytes are described for a generic keyboard.
