Getting IotHub DeviceId with azure functions

votes

I have setup routing to a Service Bus Queue using Azure IoT Hub. I followed this tutorial to get it working: https://azure.microsoft.com/en-gb/blog/how-to-use-azure-functions-with-iot-hub-message-routing/.

In my function I am trying to get the DeviceId so that I can verify the device that the message came from. I have a string parameter called message which receives The message I have sent. However, I need to get the DeviceId from the message. I tried to change the type to EventData but I got a serialisation error because of the JSON message type I think.

I will update this post with the actual code and error message tomorrow but wondered if anyone had come across this issue?

Since you get it from Service Bus Queue, you should be using BrokeredMessage class instead of EvenData. – Mikhail Shilkov

Since you get it from Service Bus Queue, you should be using BrokeredMessage class instead of EvenData.

You should be able to extract Device Id from it.
