Application Development Resources

The IoT platform provides a wealth of RESTful APIs and SDKs to ease application development. Application development is the process in which an application calls APIs of the IoT platform to implement service scenarios such as secure access, device management, data collection, and command delivery. Download the corresponding resource files as required.

Application Development Java SDK

The Java SDK provides Java methods to call RESTful APIs to communicate with the IoT platform. The Java SDK Demo provides the code sample for calling the SDK APIs.

For details, see Northbound Java SDK API Reference and Java SDK Usage Guide.

Device Development Resources

The IoT platform allows device access using MQTT or LWM2M/CoAP. Devices can connect to the IoT platform by calling device APIs or integrating with SDKs.

Certificates

In some scenarios where a device and NA connect to the IoT platform, the corresponding certificate must be loaded to the device and NA. Click here to obtain the certificate files.

NOTE:

This certificate package is used only for interconnection with the IoT platform deployed on HUAWEI CLOUD.

For details about the directory structure of the certificate package and the usage of each certificate, see Table 1.
