The software solution is an open source development called "SiK". It has been re implemented to suit the new processor architecture available on the 32bit ARM processor core. A boot loader and interface is available for further development and field upgrade of the modem firmware via the serial port.
Most parameters are configurable via AT commands, Eg. baud rate (air/uart), frequency band, power levels.
Integrated support for configuring the RFD868 radios is supported by APM Planner.
The default settings are at 57600 baud, N, 8, 1, and 200k air data rate.
The RFD868ux manual is here: RFD900ux Manual

Frequency hopping spread spectrum (FHSS)
Transparent serial link
Point to Point
Configuration by simple AT commands for local radio, RT commands for remote radio
User configurable serial data rates and air data rates
Error correction routines, Mavlink protocol framing (user selectable)
Mavlink radio status reporting (Local RSSI, Remote RSSI, Local Noise, Remote Noise)
Automatic antenna diversity switching on a packet basis in real time
Automatic duty cycle throttling based on radio temperature to avoid overheating
The modem is designed for system integrators who will integrate the modem into their own projects and product prototypes. The user is responsible for compliance with local regulations for radio transmitters.
