🌐 Raspberry Pi 4 - Local S.C.E.N.T Shelf Openthread Border Router & Embedded PC

📖 Overview

• It acts both as an OpenThread Border Router and as the central processing unit, handling and relaying communication between the Silabs microcontrollers and the server over a local LAN network.

---

✨ Key Technologies

• 🌐 OpenThread Border Router: Acts as the Leader of a Thread network on the shelf, paired with an RCP - EFR32MG21 USB Stick, and connects with child nodes (Silabs microcontrollers).
• 💻 Frontend: Provides an interactive interface for customers through an LCD Tablet directly on the shelf.
• ⚙️ Backend: Handles database polling and backend logic, exchanging data via **Redis / UART / UDP Thread

🖥️ Build Environment Setup

Linux ( Raspberry Pi 4)

1. Update hệ thống: sudo apt update && sudo apt upgrade
2. Cài Python ≥3.9, pip, Git, Redis
3. Clone repo và build firmware bằng make all
4. Cài đặt PostgreSQL
5. Cài đặt Redis

---

Start Running

1. Install OTBR (OpenThread Border Router) or use the provided container.
2. Configure config.yaml / .env:
   • MQTT_BROKER, MQTT_PORT, MQTT_USER, MQTT_PASS
   • THREAD_INTERFACE (serial / NCP device)
3. Start services (systemd or container):

cd raspi4_otbr_lcd
docker-compose up -d   # if containerized
# or follow the README in this folder for system-level setup


## Notes

- Ensure `MQTT_BROKER` in `.env` points to the running broker.
- If Socket.IO is used, configure Redis or the chosen message backend.
