Reply To: Intermittent Data to SD Card

What do you mean by “it has told me the file belongs to another station”?   The Mayfly is giving you that warning?  Or do you get that warning if you try to manually upload files to MonitorMyWatershed.   How many files are on the microSD card after a week-long or month-long deployment?  It should be one continuous file unless the logger is restarting or crashing.  Do you delete the old files or format the card after using it on a PC (not Mac)?  What is the storage capacity of the microSD card?  What brand is the card?

And what do you mean by “About two months ago I had to replace the card and software with new, the latest card and software.  I did not swap in old hardware or software.”  Those two sentences seem to contradict themselves.  Are you saying you replace the Mayfly Data Logger board or not?  Or did you reprogram the existing board with a new or existing sketch?
