Device-side development-Link Living-阿里云帮助中心

You can develop the device side using the IoT Platform Link Visual device-side SDK and the low-power solution device-side SDK. The low-power solution SDK consists of two parts: a video chip-side SDK and a Wi-Fi module-side SDK.

Prerequisites

Create a product in the console, and complete the product's function definitions and parameter settings. For more information, see Create a product and configure the app.

SDK introduction

Link Visual device-side SDK

For more information about the Link Visual device-side SDK for video services, see SDK introduction.

Low-power solution device-side SDK

Table 1. Function introduction
SDK name	Running location	Description
lv_proxy	On the video chip	Implements the low-power solution without modifying the Link Vision SDK.
lv_comm	On the Wi-Fi module	The lv_comm SDK handles heartbeat keepalive, maintains persistent connections, and enables data pass-through.

Video chip-side SDK

// Process flow
// Initialization
lv_proxy_start();
lv_init();
IOT_Linkkit_Connect();
// During runtime
while(1) {
    //
}
// Exit
IOT_Linkkit_Close();
lv_destroy();
lv_proxy_stop();

Wi-Fi module-side SDK

API operation	Function
lv_comm_api_init	Initializes the SDK.
lv_comm_api_data_input	Writes data received from the main controller. This operation returns `LV_COMM_CODE_SUCCESS` for success or another error code for failure.
lv_comm_api_status_set	Sets the `lv_comm` status. For more information, see the developer document.
lv_comm_api_opt_set	Sets SDK-related properties.
