IoT Platform:Use a device SDK to connect a device to IoT Platform

IoT Platform console

To develop a device, you must first complete the required operations and obtain the required information, such as the information about devices and topics, in the IoT Platform console.

For more information, see Create a product, Create directly connected devices, Add TSL features and Manage Topics.

Select a device SDK

Develop a device by using Link SDK

To connect a device to IoT Platform, you can integrate Link SDK provided by IoT Platform with the device. After you develop the device and connect the device to IoT Platform, the device is activated and displayed as an online device in IoT Platform.

SDK features may vary based on the programming language and applicable platform. For more information, see Device connection by using Link SDK.

Develop a device by using IoT as Bridge SDK

Alibaba Cloud IoT Platform supports communication over Message Queuing Telemetry Transport (MQTT), Constrained Application Protocol (CoAP), or HTTP. Other types of protocols, such as the fire protection agreement GB/T 26875.3-2011 and Modbus, are not supported. If you cannot directly connect a device to IoT Platform in some cases, you can use IoT as Bridge SDK to deploy a bridging service and establish the two-way data exchange channel between the device and IoT Platform.

For more information, see What is the IoT as Bridge SDK?, Use the basic features and Use the advanced features.

Develop a device based on the Alink protocol

If the available device SDKs cannot meet your business requirements, you can develop devices in a custom manner. For example, you can use an open source MQTT client to access IoT Platform.

For more information, see:

• Use the Paho MQTT Java client

• Use the Paho MQTT C# client

• Use the Paho MQTT for embedded C library to connect a device to IoT Platform

• Use the Paho MQTT for C library to connect a device to IoT Platform

• Use the Paho MQTT library for Go to connect a device to IoT Platform

• Use the Paho MQTT Android client

• Use the Paho MQTT library for Python to connect a device to IoT Platform

• Use the Paho MQTT library for Rust to connect a device to IoT Platform
