You can buffer your samples and write them, say, by 10 in one record.

the FDS library is adding 12 bytes with each record due to this I am not able to store as much data as I want (300kb). is there any way I can save without the header?

Hello,

I am glad to hear that you are able to save your sensor data!

[quote user="Rajat23"]but it is not clear how much data I can save? and what will be the starting address of available space?[/quote]

The FDS library writes from the top of the flash to the bottom, and uses the CODE_START _END and _SIZE compile-time macros from app_util.h to determine how many flash pages is available. If I remember correctly the FDS example prints the number of available pages upon startup. You could take a look there to see how this is implemented.

Best regards,
Karl

Hi,

you can look at FDS example in SDK.
