This is for my thesis project for BSECE. and I am a newbie when it comes to arduino. For context, I am making a post accident device on which I have sensors that has to send data to the internet cloud, so a mobile app could receive it.
From my research, GSM SIM7600 4G seems to be the perfect module for this, since it has the ability to connect to then internet using the sim card's internet data.
I can only see tutorials about using arduino IOT for this type of project and then making the interface into the arduino IOT itself. What I want to do is a separate app, that could be possibly downloaded from an app store and then have it communicate with the arduino through internet cloud.
Do you have some experience with this? if so, please help me understand on how it is going to be done.
