Subject of the issue

The logger doesn't write to the SD card the last minute when you power it off

Your workbench

What version of RTK firmware are you running? v4

Steps to reproduce

Log data to sd card
write down when you power off the RTK Express
check the timestamp of the last point recorded

Expected behavior

If you stop at 6H50, the last recorded point is at 6H50

Actual behavior

The last recorded point is at 6H49mn03

Same for me. RTK_Express with firmware 4.0.

(violet : NMEA logged by Lefebure; multicolored : NMEA logged on the SD card).

You can see that the track logged in the RTK Express is stopping before the one recorded in the smartphone (don't look at the strait line that is just linked to the next start).
