Key concepts

Device Update for IoT Hub is a managed service that enables you to deploy over-the-air updates for your IoT devices. The client library has three main components:

• Updates: update management (import, enumerate, delete, etc.)
• Devices: device management (enumerate devices and retrieve device properties)
• Deployments: deployment management (start and monitor update deployments to a set of devices)

Troubleshooting

Logging

Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the AZURE_LOG_LEVEL environment variable to info. Alternatively, logging can be enabled at runtime by calling setLogLevel in the @azure/logger:

import { setLogLevel } from "@azure/logger";

setLogLevel("info");

For more detailed instructions on how to enable logs, you can look at the @azure/logger package docs.
