Hello. I am trying to add groups for Azure Iot Hub devices by adding tags in Device Twins. but when i check Groups and Deployments under Update section there is no any Group to deploy update. any idea what i am missing ?

Hi @Shota Greetings! Welcome to Microsoft Q&A forum and thank you for posting the question here. when i check Groups and Deployments under Update section there is no any Group to deploy update. Adding the Tag name alone would not populate the Group name under the Groups and Deployments tab. You would need to have an Update imported into the IoT Hub platform and have the deviceupdate-agent installed on your Edge device and it should target the update on the IoT Edge device. The Azure IoT Hub device update would need access to your IoT Hub to perform updates. Refer the resource Configure access for Azure Device Update service principal in linked IoT hub to follow the steps needed to set the permissions. Please make sure the Azure Device Update service has IoT Hub Data contributor role for the updates to work Refer the below image for reference on the permissions. If you are planning to update device packages, please follow the tutorial Device Update for Azure IoT Hub using the package agent on Ubuntu Server 18.04 x64 that will guide you on the steps needed to set up and import an update. Here is a reference of the file we need to edit using the command sudo /etc/adu/du-config.json as a part of the device update process. After doing the above step, you can then add the local tag and proceed with Import the update step. After you have done that, you will find the group name in the Group and deployments tab. Refer the below image. If you plan to update a device image, please follow the steps outlined in the article Device Update for Azure IoT Hub using the Raspberry Pi 3 B+ reference image as a refer. Please let us know if you have any issues or need further clarification in the comments section below. We would be happy to help you. If the response helped, please do click Accept Answer and Yes . Doing so would help other community members with similar issue identify the solution. I highly appreciate your contribution to the community.

Hello, Thanks for replay.

I am using ESP32 with Freertos Azure C sdk. on the device side i have already flashed the ADU project sample, and the Azure Portal side i have created Device Update and import two update files as it was referenced in the sample's documentation.

but when i add tag in twins, i have problem.

could you clearify what do you mean exactly to add deviceupdate-agent on the device side ?

Hi @Shota Apologies for the delayed response on this. I have been working on this issue internally to get the correct resources to assist you. Device Update functionality can be broken down into three areas: agent integration, importing, and management. When an update command is received on a device, the Device Update agent executes the requested phase of updating (either Download, Install and Apply). In simpler terms the device update agent is responsible for applying the updates to the devices. Please refer the device update agent workflows to get a better understanding of how updates work and how they are applied to the devices. Device Update supports a broad range of IoT operating systems—including Linux and Azure RTOS (real-time operating system)—and is extensible via open source. Device Update agents are built and provided for Ubuntu Server 18.04, Ubuntu Server 20.04, and Debian 10. Device Update for IoT Hub also provides open-source code if you aren't running one of the above platforms. You can port the agent to the distribution you're running.

I am using ESP32 with Freertos Azure C sdk.

I see that you are using ESP32 device. Since this platform isn't supported by default, you would have to leverage the open-source code provided on the GitHub to build a custom Device update agent compatible with ESP32. Here is the link to the guide that will help you in Porting to a Different OS or Platform Please let us know if you have any additional questions or need further clarification on this. If you face any issues developing the device update agent, I recommend opening an issue on the GitHub so that the product team can engage and assist you further.

Hello, thanks again for your response

I am using the recourses you referenced to me. I have successful connection to server and also i am sending successfully Agent state as a idle. so i do not think problem with ESP32 Side. I think i am missing something on azure portal side.
I have open issue in Github repository but no answers.

Hi @Shota Thank you for your response. I have noticed a similar issue has been reported in the past on GitHub stating there are no groups to display in Groups and Deployments. Here is the link for your reference -- https://github.com/Azure/iot-hub-device-update/issues/378 The resolution the GitHub states that they would have to Start a device sync from the Diagnostics tab of the Updates to reflect the groups and deployments. I appreciate it if you can give this a try and let me know if that helps. I am pasting the GitHub issue you have created here for further tracking https://github.com/Azure/iot-hub-device-update/issues/451

Thanks for the references but it could not help me for my case. after syncing it returns "The last device sync job failed" and nothing is new in Group section.

Hi @Shota Greetings! Thank you for your response. Could you please confirm if you are using the sample file template Azure_IoT_Adu_ESP32 from the Azure SDK for C Arduino sample to test the device update? The library has a built-in sample model compatible with ESP32 which should work without any issues. Please review the instructions on how the device updates images are build and imported on ESP32. Please let us know if you follow the same steps and still experience the same issue. We would be glad to connect with you offline and help you further to address the issue.
