radio-edge-node

This repository contains the containerized supervisor and OP25 instance for the SDR nodes. It manages the local RF workload and synchronizes state with the central C2 via MQTT.

2. Supervisor Logic

The supervisor performs three main tasks:

MQTT Phone-Home: On startup, it sends the Check-In packet to the C2.

Process Management: It wraps the OP25 multi_rx process. If the process dies, the supervisor can report the failure via MQTT.

Metadata Tailing: (Planned) Tailing the OP25 stderr/stdout to extract real-time talkgroup grants for the C2 metadata bus.

3. Deployment

Set your .env variables (NODE_ID, MQTT_BROKER, etc.)

docker-compose up --build -d
