Device Update for IoT Hub authentication failure in Azure portal with correct access control

Question

Hello everyone,

I'm experiencing some issues with my device update component in the Azure Portal.

I have an IoT Hub in "Tier 1" and linked it to a Device Update account I created.

I've folowed the guidance for configuring access control roles for Device Update resources ([https://learn.microsoft.com/en-us/azure/iot-hub-device-update/configure-access-control-device-update?tabs=portal#configure-access-for-azure-device-update-service-principal-in-linked-iot-hub).

But I still have the folowing error when trying to work with a Device Update instance :

My user Labs has Owner and administrator role over the Device Update resource, and the linked IoT Hub has the IoT Hub Data Contributor role over Azure Device Update :

Finally when I try to find a group of devices using the "ADUGroup" tag, it doesn't show :

Any help on this issue would be greatly appreciated because I don't have any other idea at this point :(

Thanks in advance,

Aloïs KYROU

Hello, thank you for posting this question. To ensure that the permissions are assigned correctly please follow the steps below for validation.

1. In the Azure portal, navigate to the IoT hub connected to your Device Update instance.
2. Select Access Control(IAM) from the navigation menu.
3. Select Check access.
4. Select User, group, or service principal and search for 'Azure Device Update'
5. After clicking on Azure Device Update, verify that the IoT Hub Data Contributor role is listed under Role assignments

Please let us know your observation on the above check.

Hello Morten Lykkegaard, Sorry i, just confirmed with the Product team that this feature is not supported in Azure IoT Central.

The Good News is, Few of the customers are able to achieve this via Azure IoT Central's Jobs:

You can use Azure IoT Central to manage your connected devices at scale through jobs. Jobs let you do bulk updates to device and cloud properties and run commands.

Manage devices in bulk in your Azure IoT Central application

Azure IoT Central Jobs can be useful in a variety of scenarios, including:

• Firmware updates: You can use Azure IoT Central Jobs to remotely update the firmware on your devices.
• Configuration changes: You can use Azure IoT Central Jobs to change the configuration of your devices, such as modifying network settings or enabling or disabling features.
• Maintenance operations: You can use Azure IoT Central Jobs to perform maintenance operations, such as rebooting devices or clearing cache.

With Azure IoT Central Jobs, you can create jobs in the cloud, specify the target devices or groups of devices, and then monitor the progress of the job. The device can receive the job and execute it in the background, while continuing to send telemetry and perform other tasks.
