Connecting a Device

API Function

This API is used to connect a device to the IoT platform after the device is bound to the IoT platform for the first time or the device restarts.

API Description

1
 
public static boolean login();

Class

LoginService

Return Value

Return Value

Description

true

Success

false

Failure

Return values only show API calling results. For example, the return value true indicates that the API is called successfully but does not indicate that the connection is successful. The connection is successful only after the LoginService broadcast is received. Before the connection, the API for Configuring Login Parameters (LoginConfig.setConfig) is used to transfer the required connection information.

Example

Call this API to connect a device to the IoT platform.

1
 
LoginService.login();

Implement the observer API provided by the AgentLite before calling this API.
