Software / GCS Support:

Most parameters are configurable via AT commands, Eg. baud rate (air/uart), power levels.

Integrated support for configuring the RFD900 radios is supported by APM Planner.

The default settings are at 57600 baud, N, 8, 1, and 64k air data rate.

The RFD900x-AU manual is here: RFD900x Manual

The RFD900x-AU SiK software manual is here : RFD900x Peer-to-peer Manual

Software features include:

  • 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 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 RFD900x-AU is 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.
