I tried out the “Sleeping Mayfly logger example” and after I had installed the needed libraries and the sketch compiled I got an “SD card missing” error. The problem was that SD_SS_PIN in the example was 11. Worked fine when I changed it to 12. Is this the case for all Mayfly boards or was there a revision somewhere?
While playing with this code my RTC got reset and this has happened a number of times and I am fairly confident that the watch battery is snug. Any thoughts on why this is happening?
