Adding a Device

This API is used to add a device that accesses the IoT platform through the gateway. After the device is connected to the IoT platform, the IoT platform will assign a unique logical ID to the device.

public static boolean addDevice(int cookie, IotaDeviceInfo deviceInfo);

Class

HubService

Parameter Description

HubService.addDevice(29011, new IotaDeviceInfo("nodeId", "manufacturerId", "deviceType", "model", "protocolType"));
