How to Configure Gateways in ThingsPro Edge Using Azure Device Twins Tech Note
■Device twins are JSON documents that store device state information including metadata, configuration, and conditions. Azure IoT Hub maintains a device twin for each device that you connect to the IoT Hub and leverages it to synchronize device configuration and conditions.
■The JSON content of a device twin includes:
▲Desired Properties: Can be modified by back-end applications and are readable by the device application, i.e., ThingsPro Edge.
▲Reported Properties: Set by the device application and are readable by back-end applications.
▲Tags: Device metadata assessable by back-end applications.
■ThingsPro Edge integrates the device-twin design. The ThingsPro Edge device twin can be set by back-end applications using the desired properties. The device state information is updated in the reported properties of the device twin and the properties are readable by back-end applications. For example, when a back-end application requests to install a new software version, ThingsPro Edge reports back with updates on the progress.
