The software included here writes data in a file named PAXCOUNT.xx, where xx can range from 00 to 99. The software starts with 00, checks to see if such a file already exists and if yes it will continue with the next number (up to 99 - in this case it will return no sd-card). So an existing file will not be overwritten.
The data is written to the card and after 3 write-operations the data is flushed to the disk. So maybe the last 3 minutes of data get lost when you disconnect the PAXCOUNTER from power.
The data is written to the card and after 3 write-operations the data is flushed to the disk. Thus, up to the last 3 records of data will get lost when the PAXCOUNTER looses power.
And finally: this is the data written to the disk:
timestamp, wifi, ble

Format of the data is CSV, timestamp is ISO8601, which can easily imported into LibreOffice, Excel, Influx, etc.
Voltage is logged, if the device has a battery voltage sensor (to be configure in board hal file).
If you want to change this please look into src/sdcard.cpp and include/sdcard.h.
