Telit And Azure IOT HUB connection

Question

Hello
I am trying to connect module Telit ME310 to Azure IOT hub.
And have some problem with implementation with using AT-commands.

I generate CA certificat and device chain with help of portal tutorial:

https://github.com/Azure/azure-iot-sdk-c/blob/master/tools/CACertificates/CACertificateOverview.md

On output i have public.pem and private pem.
And I use this client cert and private key for connection from MQTT windows client with success
After that i trying to use that cert and key to connect from Telit Module. But unsuccessful.
And have some problem with settings.

What i need to use for SSL options:
1)

>0:SSL Verify None
>1:manage server authentication
> 2:manage server and client authentication if requested by the remote server

2) I have 3 storage:

>0:certificate
>1:CA certificate
> 2:RSA Private key. Private keys with password are not supported

I fill its with CA cert and device private key , obtained with help of tutorial(above)
Does i must use Baltimore Cert as Root CA instead CA that i add in IOT Explorer?

3) Does public device cert have to include intermediate and Root CA?

Hello @Anton and welcome to Microsoft Q&A.

Can you confirm that the "DigiCert Baltimore Root" Certificate is on your device's Telit ME310 certificate store?

See: https://learn.microsoft.com/en-us/azure/iot-fundamentals/iot-security-deployment#root-certificate-on-device

Thank you!
