We used the SD card approach for collecting data from the kit. Once we clicked ‘Start Logging’, the kit LED faded to pink for the first 30 seconds or so, and then started rapidly blinking in pink afterwards. We checked the data on the SD card one minute later, and it said it had recorded once. We used a personal SD card that already has many other files and currently has available storage of 19.47 GB out of the original 64 GB. Do we need to use a new SD card, or is it an SD card-to-kit issue?
Moreover, the record didn’t show a time. Is there a way to calibrate every how often it records data?
