Problem

Problem and constraints

BLE surveillance detection, proximity tracking, and Remote ID decoding have very different data shapes and feedback needs, yet must share constrained memory, radios, display hardware, and operator controls.

Engineering approach

Architecture and implementation

Pure ESP-IDF C keeps the runtime close to the hardware. Mode-specific pipelines feed a consistent state model used by the LCD, status outputs, storage, WebSocket updates, and the embedded browser UI.

Radios

Passive BLE and Wi-Fi observation with protocol-specific decoders and bounded contact stores.

Interface

A compact LCD workflow pairs with a mobile-optimized local HTTPS console.

Field data

Optional microSD logging and offline map tiles keep useful context on the device.
