Send MKR data to web server

Hello to the forum,

Here's the deal, I have the Telit Charlie ME310G1 kit whose programming is compatible with the Arduino IDE and MKR form factors.
I should mention that this kit has a built-in SIM reader and an antenna to send data.

I have 2 sensors that are connected in i2c to this board. The data from the sensors that are received are pollutant concentration values.
I would like to be able to put this data into a csv file and then send it to an FTP web server (Telit has given me an AT command for this connection). How to do this ?

I also wanted to know if it was necessary to add an SD card shield to store the csv document and then send it to a server.

I'm a bit new to arduino :slight_smile:

If you have any clues, please let me know :slight_smile:
