Obtaining Development Resources

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.

Resource Package	Description	Download Link
LiteOS SDK	Devices can connect to the IoT platform through the integrated LiteOS SDK. The LiteOS Demo provides the code sample for calling the SDK APIs. For details, see LiteOS SDK Integration Development Guide.	LiteOS SDK
Profile Templates	Profile templates of typical scenarios are provided. Developers can customize their profile files based on the templates. For details, see Offline Profile Definition.	Profile Example
Codec Example	Demo codec projects are provided for developers to perform secondary development. For details, see Offline Codec Development.	Codec Example
Codec Test Tool	This tool is used to check whether the codec developed offline is normal.	Codec Test Tool
NB-IoT Device Simulator	This tool is used to simulate the access of NB-IoT devices to the IoT platform using CoAP for data reporting and command delivery.	NB-IoT Device Simulator

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.

**Table 1** Certificate information
Certificate Package Name	Level-1 Directory	Level-2 Directory	Level-3 Directory	Description
certificate	Northbound API	code	Java	The certificates in this directory are used when the NA calls IoT platform APIs using HTTPS. Select the certificate in the corresponding directory based on the programming language of the NA, and load the certificate to the NA.
			PHP
			Python
		postman	-	The certificate in this directory is used when Postman tests the IoT platform APIs using HTTPS.
	Agent Lite	Android	-	The certificates in this directory are used when the device or gateway connects to the IoT platform through the integrated AgentLite SDK. Select the certificate in the corresponding directory based on the programming language of the device or gateway, and load the certificate to the device or gateway.
