Introduction to IoT Device SDKs
You can use Huawei IoT Device SDKs to quickly connect devices to the IoT platform. After being integrated with an IoT Device SDK, devices that support the TCP/IP protocol stack can directly communicate with the platform. Devices that do not support the TCP/IP protocol stack, such as Bluetooth and Zigbee devices, need to use a gateway integrated with the IoT Device SDK to communicate with the platform.
- Create a product on the IoTDA console or by calling the API Creating a Product.
- Register the device on the IoTDA console or by calling the API Registering a Device.
- Implement the functions demonstrated in the preceding figure, including reporting messages/properties, receiving commands/properties/messages, OTA upgrades, topic customization, and generic-protocol access (see Demo).
The platform provides two types of SDKs. The table below describes their differences.
