Solution Overview

The ARMxy series industrial edge gateways (e.g., BL340, BL410, BL450) can be seamlessly integrated with the ThingsBoard IoT Gateway to enable multi-protocol device access, edge intelligence, and cloud collaboration. This architecture is ideal for industrial automation, smart cities, smart agriculture, and other IoT deployments.

Powered by high-performance ARM processors (RK3568, RK3588J, TI AM62x, NXP, etc.) and rich industrial interfaces (RS485, CAN, Ethernet, WiFi/4G), combined with ThingsBoard’s Modbus, OPC-UA, and MQTT support, the system forms a complete end–edge–cloud IoT solution.

Software Deployment (ARMxy + ThingsBoard Gateway)

Install required packages

sudo apt install python3-dev python3-pip python3-venv libglib2.0-dev git  

Download ThingsBoard Gateway

git clone --recurse-submodules https://github.com/thingsboard/thingsboard-gateway.git --depth 1  

After installation, type ls, and you will see a folder named thingsboard-gateway.

Prepare Python environment

Check version:

python --version

If lower than 3.8:

sudo apt install python3.9 python3.9-venv python3.9 -m venv venv source venv/bin/activate

Create a Gateway on ThingsBoard Cloud

Configure on ARMxy

cd thingsboard-gateway

Entering a virtual environment python3 -m venv venv && source venv/bin/activate  Python installation requirements

thingsboard-gateway/thingsboard_gateway/configOpen `vi tb_gateway.json` and modify the values ​​of "host" and "accessToken" to the Platform host and Access token you just recorded. Start the Gateway

Data Flow & Protocol Conversion

ARMxy collects Modbus data via RS485

The gateway converts register values → MQTT messages → cloud device shadow

Supports local SQLite data persistence

Offline buffering and automatic sync after reconnection

Typical Application Scenarios

Predictive maintenance for automotive production lines

Energy optimization in chemical plants

Smart water pump station monitoring and remote control

Cold-chain container environmental monitoring

Wind turbine fault prediction and remote diagnostics

Smart campus security & energy automation

Water treatment dosing and safety-energy linkage control

Intelligent warehouse sorting & equipment maintenance automation
