What can i do with the "config.dat"

What are the information that are stored in this “config.dat” on the SD-card ?

It is not readable with an texteditor, so how can i edit it, what are the structure of it ?

Has anybody got more information about this topic ?

Thanks in advance …

The new F/W save the config.dat in the FLASH in the STM32 instead of the card .

The new F/W has a config screen and an option like:

“Save settings at power-down” ON oder OFF.

I like ON.
