MicronetToNMEA: reconstructing a marine instrument radio bridge

MicronetToNMEA investigates Raymarine's Micronet wireless instrument protocol and implements a Teensy and CC1101 bridge to NMEA 0183. It receives Micronet traffic, converts wind, speed and other navigation data for a PC or tablet, and can send NMEA navigation data back to Micronet displays. The manual describes remaining uncertainties in the protocol.

Requirements & limits

Prerequisites: A Teensy 3.5, 3.6, 4.0 or 4.1 and a CC1101 board for the appropriate 868 or 915 MHz band are required.
Prerequisites: Arduino IDE with Teensyduino and TeensyTimerTool is specified for compilation.
Limits: The manual says some aspects of the Micronet protocol remain uncertain and the hobbyist hardware is unsuitable as a primary navigation tool.
