    Software / GCS Support:

    Note: Firmware for the RFD868 is the same as RFD900, the board identity is defined in the bootloader.  The correct file to upgrade a RFD868 is RFDSik Vx.xx rfd900p.ihx

    The software solution is an open source development called "SiK" originally by Mike Smith and improved upon by Andrew Tridgell and RFDesign. 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, etc., please see the 3DR wiki for commands below for now.

    V2.x firmware has been updated to support multipoint networking on the RFD868/900.

     

    Integrated support for configuring the RFD868/900 radios is supported by APM Planner, with other GCS solutions in development.

     

    Software features include:

    • Frequency hopping spread spectrum (FHSS)
    • Transparent serial link
    • Point to Point or Multipoint networking
    • Configuration by simple AT commands for local radio, RT commands for remote radio
    • User configurable serial data rates and air datarates
    • 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 realtime
    • Automatic duty cycle throttling based on radio temperature to avoid overheating 

     

    Compliance:

    The RFD868 is designed to be compliant with the following standards:

    • FCC Part 15.247 (Frequency hopping and digitally modulated intentional radiators)
    • AS/NZS 4268:2012 (Radio equipment and systems - short range devices)

    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.
