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 are 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 (nonmultipoint) is suitable for point to point links - the source code 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. 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 RFD900 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.
