I hope you are doing well. It has been awhile since my last ask. I recently reset my system and now I am having an issue where the mayfly is only working when it is connected to my computer. Is this an issue with my battery?
What sensor(s) are you using with the board? Have you reprogrammed the sketch onto the Mayfly recently, or are you using a board that was programmed last year or earlier? Some people seems to be having issues with boards not sleeping/waking properly using the most recently SDI12 libraries, so if you’ve recently reprogrammed the board, then that might be the issue.
