Software / GCS Support :

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 RFD900.
V1.x (non multipoint) is suitable for point to point links - the sourcecode is located at:https://github.com/RFDesign/SiK
The user manual / datasheet can be found here :RFD900 Datasheet
A software manual for SiK firmware is here :RFD900 Software manual
RFD900 configuration tool and firmware repository: RFDesign Files
3DR/RFD900 compatible configuration tool :http://vps.oborne.me/3drradioconfig.zip
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.

Les caractéristiques du logicielcomprennent :

  • 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

Le RFD900 est prévu pour être conforme aux standards suivants :

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

Le modem est conçu pour les intégrateurs de systèmes qui intégreront le modem dans leurs propres projets et prototypes de produits. L'utilisateur est responsable du respect des réglementations locales concernant les émetteurs radio.
