Usually, when I reference the Azure IoT Hub, you can expect that some telemetry is involved. But the Azure IoT Hub is evolving. A new feature is coming, it is now possible to upload blobs.
Why should we want to upload blobs? Well, I think it’s great to have the possibility to upload files full of telemetry in one upload.
But sometimes the telemetry is not a bunch of values but it’s more like a big bag of bytes 🙂 In the example below, we will upload an image and pass it on to Microsoft Cognitive Services (previously known as Project Oxford) for visual analysis.
