This setup allows devices to transmit their precise GPS coordinates to one another using the low-power, long-range capabilities of LoRa communication. We then take that received data and display the location of the remote device on a screen.

This project is an excellent foundation for developing embedded applications like off-grid communicators, simple tracking devices, or a basic mesh network.
