How to add n devices in Azure IOT hub using Azure Device Provisioning service

A Arockia Jabamalai Eldsin 20

Hi,

I create one Azure Device Provisioning service and create one IOT hub also.

In DPS service I add the IOT hub and the Enrolment Group also I created for the Device Provisioning service.

In the coding area I add the Global device endpoint and ID Scope of the DPS service and the Enrolment Group Primary key and secondary key also.

If I run the code, it is showing this error and the code was written by C#.

Hello @A Arockia Jabamalai Eldsin ,

if you use a group enrollment, each device still needs to be unique.

Check out this example based on symmetric keys explaining how to add an individual device using a group enrollment.

Hi @Sander van de Velde,

I am referring this video.

https://www.youtube.com/watch?v=OfRbGNvxyAs

You please check this and that code I run means I am getting an error, and, in this video, they use IOT Device only not the IOT Edge device.

Whatever step they follow in the video. The exact thing I follow. But if I run, I am getting this error.

Please check this error and tell me. And, for that I need to give any access for the Inbound and Outbound port. If anything, there means. Please tell the port number. I will check that.

If you have any example like that, please share me.

Hello

I see you get an AMQP protocol error.

This could be the result of multiple issues. Perhaps the outbound port 5671 is not open?

You could try MQTT of perhaps MQTT over Websockets too.

I recommend starting with a simple test first, like connecting a device simulation to the IoT Hub first. (Here is a Python example; Python sample code here ; C# sample).

Notice the Python example connects over websockets (port 443, outbound).

From there, try an individual enrollment with a symmetric key.

If this works, try the group enrollment.
