Hi Zainu, as an other user of the FM3001 I thought about connecting it to the Azure IOT Hub. However, what I found at the time is that the IOT hub only receives json or mqqt messages. This means before you can send the Teltonika device data to the server you will have to do some parsing yourself because the FM3001 only sends raw byte data and the IOT Hub does not know how to process that out of the box.
This means you will have to write your own parser and forward the received data as json to the Azure IOT Hub.
