IoT Platform:Obtain the SDK

Procedure

1. Log on to the IoT Platform console.

2. In the left-side navigation pane, click Documentation and Tools.

3. On the Documentation and Tools page, click SDK customization in the Device Access SDK section.

4. On the SDK customization page, set the parameters. Click Start generation to download the SDK.

   

   You can download the SDK file to a specified location based on the browser prompt. The following table describes the structure of the SDK after the file is decompressed.

   Folder or file	Description
   ./LinkSDK/ChangeLog.md	This file contains the update time of each module in the SDK.
   ./LinkSDK/components	This folder contains subfolders of customized modules.
   ./LinkSDK/core	This folder contains the files that provide core code about device connection.
   ./LinkSDK/demos	This folder contains sample code files that provide basic features and customized advanced features. Note When you port the SDK, you do not need to add the demos folder to the compilation system.
   ./LinkSDK/external	This folder contains the mbedtls C library. The SDK provides a third-party mbedtls library. To use the TLS feature, you can use other TLS-related libraries.
   ./LinkSDK/Makefile	This file is used to compile the SDK.
   ./LinkSDK/portfiles	The file defines the TCP/IP protocol stack and system-related API operations. If the SDK does not define the TCP/IP protocol stack based on the operating system, you must port the functions in the portfiles file.
