Device firmware updates
The backend app is responsible for initiating a firmware update for the device through a direct method that it can run on the IoT device. The device then acts and downloads the firmware file, runs the firmware update, and finally reconnects to the IoT Hub service. Throughout the process, the IoT device uses the reported properties to update the progress and status of the device.
