When the gateway is offline, it can call the API for Gateway Updating Child Device Status to send the latest status of child devices to the IoT platform. What Are the Differences Between Device ID, Node ID, and IMEI and What Are They Used For?

If the device is an indirectly connected device, the gateway ID is the device ID of the directly connected device (that is, the gateway) with which it associates.

Devices that do not support the TCP/IP protocol stack, such as Bluetooth and ZigBee devices, need to use a gateway integrated with the IoT Device SDK to communicate with the platform. Create a product on the IoTDA console or by calling the API for creating a product.

Gateway Reporting Child Device Property /v5/devices/{device_id}/sys/gateway/sub-devices/properties/report This API is used to report device data in batches to IoTDA. A gateway can use this API to report the property data of a maximum of 50 child devices at the same time.
GATEWAY: a directly connected device or gateway.
If the device is an indirectly connected device, the gateway ID is the device ID of the directly connected device (that is, the gateway) with which it associates.
