It's great that Azure Iot hub and sdk supports blob uploading. However it seems blob metadata uploading is not there. Any plan to add the feature? It's a very handy feature for small projects.

Or it's already supported but I missed something?

That's correct. There is no method (support) for the blob metadata uploading in the Azure IoT Device Client SDK. However, the following workaround can be used for this feature. It's based on the uploading files with IoT Hub using the REST API calls.

Step 1: The device ask an Azure IoT Hub for upload references Step1

Step 2: Upload blob and metadata Step2

Step3: Complete the device uploading process: Step3

  • Thanks Roman. This definitely works but it still seems to much move convenient to me to have it directly supported in the file uploading function in the SDK - especially given that it's a direct blob upload. – sidecus Oct 05 '17 at 05:21

This feature is tracked by https://github.com/Azure/azure-iot-sdk-csharp/issues/165 for the .NET Azure IoT SDK.
