Function
This API is used by an application to freeze a device. After a device is frozen, it cannot connect to the platform. You can use the API "Unfreezing a Device" to unfreeze the device. Currently, only devices that are directly connected to the platform can be frozen. This API can be used to freeze a single device. For details about how to freeze devices in batches, see Creating a Batch Task.
