What is the optimal accelerometer frequency to send movement data?
I know that “better frequency - better”, because more data - more precision, but what is the frequency value when like if making it less can lead to loose critical data for sleep result accuracy? Like 1Hz or 3Hz or… ?
Should I send
com.urbandroid.sleep.EXTRA_DATA_FRAMERATE value for accelerometer movement data in
com.urbandroid.sleep.watch.DATA_UPDATE movement data intent or it’s only for HR, RR, SPO2, SDNN ?
