Notes :
1)
The device only wakes up and performs data sampling according to MinTime Interval.
When it is sleeping, it does not collect data.
2)
The data collected is compared with the last data reported. If the data variation is greater
than the ReportableChange value, the device reports according to MinTime interval. If the
data variation is not greater than the last data reported, the device reports according to
MaxTime interval.
3)
We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is
too low, the device wakes up frequently and the battery will be drained soon.
4)
Whenever the device sends a report, no matter resulting from data variation, button pushed
or MaxTime interval, another cycle of MinTime/MaxTime calculation is started.
