LoRa APRS Tracker Software (DL9SAU & Community)

A powerful, community-driven firmware that turns ESP32 modules into versatile LoRa APRS trackers with KISS TNC capabilities.

This software allows amateur radio enthusiasts to build their own powerful APRS trackers. It can operate as a standalone device sending its own GPS position, or connect to other devices like smartphones and computers to act as a wireless modem (TNC).

Standalone Tracker

Uses its built-in GPS to automatically report its position over LoRa, with Smart Beaconing to optimize transmissions.

KISS TNC Mode

Connects via Bluetooth to apps like APRSdroid or via serial to act as a modem, sending and receiving APRS packets.

Core Features

Packed with features for flexible and efficient APRS operation.

Bluetooth TNC

Connect wirelessly to your phone (e.g., APRSdroid) and use the device as a TNC modem.

Web UI Configuration

Easy setup via a web browser. Connect to the device's Wi-Fi AP to change all settings.

Smart Beaconing

Intelligently adjusts transmission rate based on speed and course changes to save airtime.

OTA Updates

After the initial flash, subsequent firmware updates can be performed wirelessly via the web UI.

OLED Screen Support

Provides real-time status updates on GPS fix, packets sent/received, and device status.

Power Management

Manually toggle GPS power and configure auto power-off to extend battery life.

Compatible Hardware

The tracker software supports a specific range of popular ESP32-based devices.
