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.
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 : RFD868/900 Software manual
RFD868/900 configuration tool and firmware repository: RFDesign Files
3DR/RFD868,900 compatible configuration tool : http://vps.oborne.me/3drradioconfig.zip
Integrated support for configuring the RFD868/900 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:
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.
