Calibration needed after every battery drain?

liormessinger

Hi everyone

Our problem is that every time the battery drains, or we do a reset, we get MBL_MW_SENSOR_FUSION_CALIBRATION_ACCURACY_LOW
for both the accelerometer and the gyroscope.

we get this value on the data sent to the calibrationCallback that initiated from
m_calibrationSignal = mbl_mw_sensor_fusion_calibration_state_data_signal(m_metaWearBoard);

mbl_mw_datasignal_subscribe(m_calibrationSignal, this, calibrationCallback);

Any idea what we should do to fix this? we cannot have our customers calibrate every time the battery runs out.

Also, it somewhat **contradicts ** what @stephen said on this answer, as it seems that the accuracy is not permanent.

We do not use magnetometer for the sensor fusion

thanks!
