Arduino with UART LoRa module as Simple APRS Tracker

This project is using a Arduino to decode GPS position information, and encode it into APRS packet, then send it over the air using UART LoRa module.

Only Arduino Mega 2560 or similar Arduino board with multiple hardware UART is supported.

Operating Principle

It receives GPS data from hardware serial port 3 (Serial3), and sends non-standard AX.25 frame (checksum is omitted) to hardware serial port 1 (Serial1).

Library Dependency

This project needs TinyGPSPlus to parse NMEA sentences.

Todo

Send compressed coordination to improve position precision.
