Yes that's exactly what I meant. I never touched the threshold settings. it's
set to 0.
But in contrary I made the experience that when I was normally walking and
logged the Acc with 2G Settings I got only 50 measurements in 15 Seconds.
That means perhaps I reach the maximum value of 2G even when the Freerunner is
lying flat on the table, maybe due to noise?
This would explain why it works with 8G scale.
I'll do some measurements with 8G scale and check how often it reaches the 2G
I'll also try it with select() function that Thomas White mentioned and hope
that it helps.
