# 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.)
|
|
|
|
```bash
|
|
docker-compose up --build -d
|
|
``` |
