Azure DPS: more parameters in the query

Question

Azure DPS: more parameters in the query

BERNARD Thomas 166

Hello all,

I am using Device Provisioning Service for the registration of my devices in Azure IOT Central. Everything is OK, but I would like to send more than the "registration ID" in the payload.

I got that description: https://learn.microsoft.com/en-us/rest/api/iot-dps/device/runtime-registration/register-device

I know that is possible to send the model ID in a specific part of the request ("payload"). Is it possible to also give the "Device Name" ?

Do you have the complete description of the available parameters in that request ?

Thanks in advance,

Hello @BERNARD Thomas ,

Azure IoT Central is a SaaS platform for IoT. It is based on Azure IoT PaaS resources like IoT Hub, Aure Stream Analytics, and Device Provisioning Service.

The reference documentation you found is for the full Device Provisioning.

The DPS supports adding an alternative Device ID and Device Twin Tags.

These are provided to the IoT Hub chosen by the DPS so the IoT Hub can create the device registration and eg. start automatic device configuration.

Because you use Azure IoT Central, you are limited by what is offered in the current interface, either the portal or the REST API.

At this moment, both interfaces are not offering support for adding DPS tags. You can only provide the registration ID and optional device ID (I assume this is the 'displayName').

Thanks for the answer @Sander van de Velde | MVP

I am using MQTT to request the device's registration directly from the device into the IOT Central application (through the DPS integrated into IOT Central).

So if I understand correctly, there is no way to manage the device name from the MQTT payload ?

I send this json:

{ "registrationId": "45d7f940-bda3-11c8-86fc-413938373635", "payload": { "displayName": "myIOTCentralDevice1", "modelId": "dtmi:CustomBlablabla:DeviceA;1" } }

And I do not see the right "device name":

Hello @BERNARD Thomas ,

in IoT Central, the device name is optional. If only the registration id is provided, the device name will be the same as registration id.

I have no experience with using MQTT for registering a device.

The Rest API support both device identifications (the ID in the URL and name in the body).

Which SDK are you using? Can you share a link?

I am using my own SDK in C/C++ (not the one provided by Microsoft).

I see that the "device name" and the "device ID" take the value received from the "registration ID". But in my case I can provide a user friendly name, but I don't find how to send it. Maybe this is just not possible ?

To resume, I just need the description of parameters I can put on the "payload" part of the JSON, when I use MQTT with the DPS provided in the IOT Central applications.

Thanks again for you support !

Ok, so I will drop the set of the device name during the registration by MQTT.
Maybe that could be put in the feature backlog of IOT Central ...
Thanks for the support.
