Help with Azure Plug and Play Geospatial schema

Question

I'm working on creating a new Azure Plug and Play model. I like to use the Azure IoT Explorer application to test/validate my PnP implementation.

I've defined a entry in my model for GPS data, however when I send the data, the Azure IoT Explorer application does not resolve my telemetry data to the model entry. I found a DTDLv2 reference showing details for Gelspatial data here. This looks pretty straight forward.

Here's where I am . . .

• I've created my DTDL model (line 111) and validated it using the MSFT Validator example

• My application is sending up proper JSON telemetry
  
• However, if I select the Azure IoT Explorer option to "Show modeled events" the telemetry is not resolved to the model

Any idea what I'm doing wrong?

Thanks for the help!

Hi @Anonymous ,
Could you try lowercasing the "type" value? ("Point" -> "point")

Thanks for your time, I'll create a bug report in that repo and also on the documentation page that specifies the capital "P"oint string.

I thought about just trying this with an IoTCentral application to see if it works correctly, but I don't see a way to configure IoTCentral to resolve my PnP model without submitting it to the public PnP repo. Is there a way to have IoTCentral resolve my model from a different repo where I can make changes to my model?

Thanks
