IOT Hub Control Device without SDK - Using MQTT

Question

Hi I have followed this guide successfully:

https://learn.microsoft.com/en-us/azure/iot-hub/quickstart-control-device?pivots=programming-language-csharp

What I would like to do is replicate this such that the device sending telemetry is my MQTT device publishing its topics to the IoT - (which I think is just a case of connecting it to the hub)

And then using an app on a smart phone to Call the direct method which would effectively said a on or off flag to the device.

When I look at the CS code for this it appears a lot of the heavy lifting is being done by the SDK.

Is there any guide that provides information on how to do this without the sdk

Hello @Red255 ,

The Azure IoT Hub supports communicating over MQTT without the SDK.

Check this tutorial because the format is very specific.

The new support for MQTT5 is still in preview.
