Hello there from Poland! :) what a great piece if code you have managed to make here. I'm looking for way to extract comment data from freestyle libre app to file, but i cant figure out a way to do it. Could you please help me with finding a way to do it, even with a little tutorial where and how exactly to use your bash code :)

Hi @Thrajnor,
I'm sorry I don't have a clue. I copied and slightly adapted the script freely from this website https://www.surlemont.fr/dotclear/index.php?post/2017/02/18/Exporter-VOS-donn%C3%A9es-de-l-application-LibreLink to help the diffusion of this nice script but I haven't explored it further.
Good luck!
