We have a mayfly deployed at a test site which inexplicably stopped recording data, and I’m hoping to see if anyone else had experienced similar issues or has any insight.
A couple of days ago, we noticed that data was no longer being sent to the data portal so we brought the board and sensors back in from the field. The first thing we did was turn the board off to remove the SD card and saw that data had not been logged to the card. We then put the SD card back into the board, turned on the board, connected it to a laptop, and launched Arduino’s serial monitor. The serial monitor spat out a few lines indicating the board had been successfully initialized and started its routine. New measurements were then logged onto the data portal as if there was nothing amiss.
Has anyone else experienced similar stoppages, or does anyone have any ideas for what may cause a stoppage? Fortunately this is only a test site, but we would like to be prepared when we deploy to more remote systems. Thanks for your help!
