Connect SIM7020 to Azure IoT-Hub

Hi everyone,

I am trying to connect my SIM7020 board to an Azure IoT-Hub via MQTT protocol.

The https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/nbiot/SIM7020%20Series_MQTT(S)_Application%20Note_V1.05.pdf of the module has an example with AT-commands starting on page 16.

However, I don't know which of all these certificates I need and how/where to create them.

I have created a local root certificate on my PC and added it to the IoT-Hub under 'certificates', but I still cannot get the device connected and in the example I need more than one server/client certificate.   

Does anyone of you have experience with connecting a device to IoT-Hub via MQTT or at least the SIM7020 module itself?

Thanks,

Niklas
