rfskipper-decoder

Introduction

RFSkipper-decoder main functions :

• Connect the RFSkipper Gateway through the serial / usb serial interface
• Listen of incoming RF pulses
• Publish the pulses in a 'signal_raw' topic
• Try to decode the pulses with embedded decoders and eventually publish decoded messages on the 'signal_decoded' MQTT topic

Build and run

• Run local MQTT Broker (Optionnal)

If you don't already have a MQTT Broker, you can install one local instance of Mosquitto MQTT broker.

Instructions for Linux (ArchLinux)

$ pacman -S mosquitto 
$ systemctl start mosquitto
$ systemctl enable mosquitto
