RFDesign - RFD 868x Bundle

General

The RFD 868x Bundle by RFDesign. Besides antennas and cable, it contains two RFD868+ Long Range Modem with 1 Watt transmission power. This enables ranges of up to 40km. The software "SiK" is an Open Source development. A Boot Loader and interface are provided for adjustments of Model Firmware via a Serial Port.

Features

  • Long range >40km depending on antennas and GCS setup *80km demonstrated by Edge Research labs on a balloon !, 57km in India, on Dipoles.
  • 2 x RP-SMA RF connectors, diversity switched.
  • 1 Watt (+30dBm) transmission power.
  • Transmit low pass filter.
  • > 20dB Low noise amplifier, high IP3.
  • RX SAW filter.
  • All I/O ESD protected and filtered.
  • Re implemented SiK and Multipoint SiK firmware, field upgradeable, easy to configure.

Software

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:
  • 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
