About the development of IoT Device compatible with Device Update For IoT Hub.

Question

Hello.

I am trying to create an IoT device that supports Device Update For IoT.

If you are developing on a Linux-based OS, the tutorial below states that you must first install the IoT Identity Service daemon and Device Update Agent.

• Tutorial: Device Update for Azure IoT Hub using the package agent on Ubuntu Server 18.04 x64
  https://learn.microsoft.com/en-us/azure/iot-hub-device-update/device-update-ubuntu-agent

The IoT device I am developing is based on Azure RTOS, so I am referring to the following tutorial instead of the above one.

• Tutorial: Device Update for Azure IoT Hub using Azure RTOS
  https://learn.microsoft.com/en-us/azure/iot-hub-device-update/device-update-azure-real-time-operating-system

There is no procedure to install the IoT Identity Service daemon or Device Update Agent here as in the case of Linux-based OS, instead, the sample is downloaded from the following to create the firmware.

Am I correct in understanding that using the above sample, the Azure RTOS will have the IoT Identity Service daemon and Device Update Agent installed?
Or do you mean that Azure RTOS includes IoT IoT Identity Service daemon and Device Update Agent from the beginning?

In the Azure RTOS tutorials, I'm curious that the tasks of installing the IoT Identity Service daemon and Device Update Agent, which were present in the Linux base, are gone.

Thanks in advance.

Hello @HinataGrape-6694,
Thank your for sharing great questions with the community :)!

The samples provided in the github repo pointed by the Tutorial: Device Update for Azure IoT Hub using Azure RTOS will include instructions on how prepare the new firmware, the device and deploy the new firmware for each specific board. Inside each .zip file provided (in the docs folder) you can find a pdf file with a structure similar to this:

Depending on the device you have and IDE you use, you download the specific file (IAR Workbench or semi's IDE):

In the Azure RTOS tutorials, I'm curious that the tasks of installing the IoT Identity Service daemon and Device Update Agent, which were present in the Linux base, are gone.

Those tasks are on the pdf file I mentioned above. Because each board and IDE has it's own procedures we moved that piece of the tutorial to the pdf file. Nevertheless I will pass the feedback to the Product Team to analyze other ways to share the steps besides the pdf.

To learn more about the Device Update agent within Azure RTOS NetX Duo, see feature/adu branch.

Hope I was able to clarify your questions and please continue leveraging this forum for your questions :)!
