Roll out a firmware update to a device group using Azure Device Update for IoT Hub with automatic rollback on failure
domain: learn.microsoft.com · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checked community attestations: 0✓ / 0✗
Steps Import the update (manifest plus files) into ADU; content uploads to an Azure Storage account and is processed asynchronously Organize target devices into device groups using IoT Hub tags Create a deployment that targets a device group with the imported update; deployments are dynamic and auto-apply to devices that join the group later Configure the deployment's automatic rollback policy using a percentage or minimum-number-of-devices-failed threshold Monitor update compliance (percentage of devices on the latest compatible version) and retry the deployment for devices that failed
Known gotchas only one active deployment can target a given device group at a time a canceled deployment cannot be reactivated -- a new deployment must be created update type (package-based vs image-based) must match how the device's ADU agent is configured, or the update fails validation
