How are commands sent in cloud IoT Core?

You can use Cloud IoT Core to send commands to devices. Commands are transitory, one-time directives sent to devices that are connected to Cloud IoT Core and subscribed to the commands topic. Compared to device configurations, commands are faster, can be sent more frequently, and are independent of other Cloud IoT Core features.

How to create a simulated device in AZ IoT Hub?

The simulated device sends device telemetry to your IoT hub. In the second CLI session, you monitor events and telemetry, and send a cloud-to-device message to the simulated device. To create and start a simulated device: Run the az iot hub device-identity create command in the first CLI session. This creates the simulated device identity.

How does an IoT Hub respond to a message?

When the device completes the message and responds, the gateway translate the device-specific status to the method response. The IoT Hub completes the direct method by populating a method result for the caller.
