SD card file format(FAT16, 32, etc) and failure issue

Post by siberian »

I've just tried logging obd data with data logger v4 and it failed.
So I tried with another micro sd card and it worked.
Long story short, logging obd data with old sd card(FAT32) was successful while with new 128 gb sd card (exFAT128) not.
I presume it is because of the file system that Arduino sd card library supports (https://www.arduino.cc/en/Reference/SDCardNotes).
(For your information, Arduino mainly supports fat16 and fat32 and recommends FAT16)
Has anyone, or Stanley, ever tested this issue?
If yes, please describe it in the instruction otherwise many sd cards these days won't work with Freematics products.

Tried with 120 gb sd card with exFAT16. Failed.
32 gb sd card with FAT32 works well.

FAT32 is limited to 32GB in partition size and 4GB individual file sizes.
