The software solution is an open-source development called "SiK" originally developed by Mike Smith and improved by Andrew Tridgell and RF Design. 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 RFD900 radios is supported by Mission Planner.
Transparent serial link
Point to Point (V1.x), or Multipoint networking (V2.x)
Configuration by simple AT commands for local radio, RT commands for remote radio
User-configurable serial data rates and air datarates
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.
