LoRa APRS iGate/Digipeater Software (CA2RXU)

Powerful open-source software that transforms inexpensive ESP32 modules into advanced LoRa APRS gateways (iGates) and repeaters (Digipeaters).

Created by Ricardo Guzman (CA2RXU), this software bridges the world of LoRa (Long Range) communication with the global APRS (Automatic Packet Reporting System) network. It allows amateur radio enthusiasts to track objects, report weather data, and exchange messages over long distances with minimal power consumption.

iGate (Internet Gateway)

Receives LoRa packets and forwards them to the global APRS-IS network, making your data available on sites like `aprs.fi`.

Digipeater (Digital Repeater)

Receives and retransmits LoRa packets, significantly extending the network's range for devices outside of a gateway's reach.

LoRa APRS Tracker Software (CA2RXU)

Transform ESP32 modules with GPS into a fully functional APRS tracker, capable of sending position, messages, and telemetry data.

This software, also by CA2RXU, complements the iGate/Digipeater ecosystem. It allows you to build mobile or stationary APRS stations that communicate with the world via the LoRa network. Ideal for tracking vehicles, hiking, or monitoring parameters.

TNC Mode (Bluetooth)

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

Full Menu & Messaging

Read, write, and delete APRS messages directly from the device.

Intelligent Transmit

Advanced encoding and SmartBeaconing minimize airtime.

Weather Data (Wx)

Supports BME280 sensors for sending weather telemetry.

Hardware Support

Broad compatibility with T-Beam, Heltec, T-Deck boards, and many others.

Power Management

Power-saving modes and a battery monitor to protect the battery.

Key Ecosystem Features
