This is a great device that you can make that will allow you to pair a bluetooth capable ham radio to an apple phone or tablet in order to do APRS, emails, sms and other ham radio digital modes over the airwaves.
Some devices, like the Kenwood TH-D74 radio only support Bluetooth Classic serial profile. iOS devices only support Bluetooth Low Energy (BLE). They are not compatible and as such, you can't pair those devices together. This code provides a way to create an adapter that can interface a device that exposes a serial profile over Bluetooth Classic, to an iOS device via BLE. Its main purpose is to enable iOS app that supports AX.25 packet like RadioMail or APRS.fi to use the TNC built in the radio as a modem.
