LoRa.Message

A pure C# library to decode packets for LoRa/LoRaWAN^TM radio communication, based on the specification from the LoRa Alliance (based on V1.0.3)

Thanks for huge inspiration to lora-packet, a node.js library to decode and encode packets for LoRa/LoRaWAN^TM

---

Packet decoding is also wrapped in a simple command-line tool that accepts input in hex and base-64

Features

• [x] LoRa packet parsing & analysis
• [x] MIC (Message Integrity Check) checking
• [x] payload decryption
• [x] decode uplink & downlink packets
• [ ] unit tests for everything
  • [x] MIC calculation
  • [x] message decryption
  • [ ] utility conversion
• [ ] decode join request packets
• [ ] decode join accept packets
• [ ] generate NwkSKey and AppSKey from AppID

Usage (in your code)

PHYPayload packet = new PHYPayload(data, nwkSKey, appSKey, 0);

Usage (command-line packet decoding)

dotnet LoRaPacket.dll decode --hex 40F17DBE4900020001954378762B11FF0D

dotnet LoRaPacket.dll decode --base64 QK4TBCaAAAABb4ldmIEHFOMmgpU= \
    --nwkskey 99D58493D1205B43EFF938F0F66C339E \
    --appskey 0A501524F8EA5FCBF9BDB5AD7D126F75
