LoRaMesh-Netowork-with-CMAC-Authentication

Fully functional LoRaMesh Network working in Arduino Uno Enabled with CMAC Authentication

Setup Instructions

Node Setup

1. Set Node ID:

   • Upload SetNodeId.ino sketch to the first node.
   • Set the Node ID to 1.

2. Upload LoRaMesh Sketch:

   • Upload LoRaMesh.ino sketch to the same Arduino Uno device.

3. Repeat for Additional Nodes:

   • Repeat the above steps for up to 255 devices.
   • Change the Node ID for each device accordingly.

Authentication Setup

1. First Node Setup:

   • Upload auth_main.ino to the first device (Arduino Mega).
   • Ensure the Node ID is set to 1 in the init.cpp file.

2. Other Nodes Setup:

   • Upload auth.ino to each additional node.
   • Change the Node ID in the init.cpp file for each node.

Notes

• Authentication Code Compatibility:
  • The authentication code will only run on Arduino Mega devices.
