Software/ GCS Support :

  • The software solution is an open source development called “SiK” . 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.
  • V2.x firmware has been updated to support multipoint networking on the RFD900
  • Integrated support for configuring the RFD900 radios is supported by APM Planner, with other GCS solutions in development.
  • The default settings are at 57600 baud, N, 8, 1, and 64k air data rate.

Software feature includes:

  • 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
