Thanks for the confirmation and the reference to the stat function

Yes, like you said, GC shouldn't be perfomed too often as it increases wear on flash. Also note that you can use the fds_stat() function to monitor the flash usage and run GC before it gets completely full.

Would it be more appreciate to ONLY "manually" invoke garbage collection when FDS_ERROR_NO_SPACE_IN_FLASH is returned to avoid excessive wear that would be caused by calling garbage collection too frequently?

Hi, Thanks for reply.

I noticed that I'm already using fds_gc() function in the FDS initialization code. Is this is something we use on repeated bases, like calling fds_gc() every time before writing data to flash?

Hello,

The error corresponds to FDS_ERR_NO_SPACE_IN_FLASH, so you need to free up more space to update your record. This is usually done by performing a Garbage collection.

Best regards,
