This project transforms the LILYGO T-Display-P4 development board into a multifunctional portable device capable of acting as a 1090 MHz ADS-B receiver and a Meshtastic-compatible mesh radio. By using an RTL-SDR USB dongle for RF reception and an onboard SX1262 LoRa radio, the system provides real-time aircraft tracking via a touchscreen interface and off-grid messaging capabilities. The device also features integrated MP3 playback, GPS time synchronization, and a companion web application called ADS-B Scope for live map viewing through WebSerial.
Main features include:
* Real-time ADS-B decoding and radar scope visualization with aircraft database enrichment.
* Meshtastic-compatible LoRa mesh networking with encrypted messaging and node discovery.
* Integrated MP3 music player with ID3 tag parsing and cover art display.
* Adaptive RTL-SDR gain control and USB hot-plug support.
* Comprehensive SD card logging for both ADS-B flight data and mesh messages.
* Dual-core ESP32-P4 architecture optimized via a 6-tier FreeRTOS priority scheme.
* WebSerial-based companion app for live mapping, firmware flashing, and file management.

A clean-room, header-only C/C++ implementation of the Meshtastic LoRa mesh protocol designed for embedded systems. This standalone library allows devices to interoperate with the Meshtastic network without requiring heavy dependencies like Arduino, RadioLib, or FreeRTOS. It handles everything from raw LoRa byte processing to decoded messages including text, position, and telemetry data.
Key features include:
- Packet parsing and AES-256-CTR encryption/decryption
- PKI direct messages using x25519 key exchange
- Channel management and PSK expansion
- Protobuf decoding for various message types without Nanopb dependency
- Radio configuration including regional settings and modem presets
- CSMA/CA implementation for MAC protocol compliance
