Hello everyone, I have an Arduino based system that logs data to an SD card.
The format of data and CSV of this type:
Date; Time; Wire temp; Temp sensor; Humi sensor; Light
01/17/2021; 00:44:40; 25.6; 24; 46.19; 100
01/17/2021; 00: 59: 41; 25.6; 24.1; 45.93; 100
01/17/2021; 01:14:41; 25.7; 24.2; 46.17; 0
Etc ....
I would like to retrieve this data, via Bluetooth or local Wifi in an application on an Android smartphone or tablet that can display this data to me in the form of a graphics. First, I would like to test the application by rereading the CSV file locally in the smartphone (CSV file) where can I find a template to start tests with MIT-App-Inventor?
Thanks for the suggestions.

Your sample data is not in CSV form.
The C in CSV means Commas (,) , but you are using semicolons ( ; )
Yes, it's SSV (semicolon) we must be able to analyse them the same, right?
There is a text replace block that you would need to change all semicolons to commas before you use the native AI2 CSV conversion blocks.
Alternatively, ask for commas upstream instead of the semicolons.
Thanks ABG, I will correct from the source. It will probably be better. Are you talking about: AI2 CSV conversion blocks? !!?
What is it exactly ?
I do not know, but if it helps I am early.
Thank you !
Yes, look in builtin list blocks section.
Ok, you say
"There is a text replace block that you would need to change all semicolons to commas before you use the native AI2 CSV conversion blocks."
I don't know the MIT app, I discovered it yesterday.
To be clearer: what is AI2? I don't know the acronyms (especially in English ...)
CSV = Comma Separated Values
