Hi Sir:     When the vibration is present, except gyro accuracy, are other accuracies changed ? They are still 3?      Do you check your BNO055 version, include SW version and other version?   ... View more

Hi Sir:     Regarding calibration, please see my following comments:     1. Before installed to your product, ACC calibration can be finished first, if no bending stress, it will not be needed to calibrate again.     2. It is easy for GYRO to calibrate, only keep sensor still and wait a few seconds, calibration will finish.     3. But MAG calibration is hard to finish, three-dimensional space is necessary. Use calibration software with standard 'figure-of-eight movements to do the hard iron calibration and compensate for distortions affecting magnetometer readings, or with the help of gyro, at least your device slope 30 degree to finish it , which way is smart calibration software with 'natural-use movements'.     So if when the magnetic field is changed, Mag calibration have to do in order to ensure to get the correct data.     If need the absolutely orientation, NDOF mode should be chosen, if don't care the start orientation，only need relative change, IMU mode can be chosen.   . ...

Hi Sir:    I am not sure whether you succeed to read out the register values. But I had a look at response.txt, I didn't see the flag I want to confirm first.    Please see the following picture:  First CHIP_ID need be read out to check whether to choose the corresponding Sensor. BMA222E CHIP ID at register 0x00 is 0xf8. You should first check whether to get this value.     ... View more

Hi Sir:      I talked to our internal guys, currenly because lack the related shuttle board, only based on what you said, we can't figure out the reason why the config file of API was failure. I re-checked our shuttle boards and get the correct result.      If you need to look for the root cause, recommend you to contact the local FAE and offer your shuttle board to do further analysis.     ...

Hi Sir:      Please see my following comments:     1. Regarding saving the calibration profile, after all accuuray are 3, you can save them. Maybe you need to save many times because of magnetic field change and gyroscope.     2. Regarding loading the calibration profile, after change power mode to normal mode before enable fusion mode, you should do it.     3.  You need to check the calibration status and store the calibration profile when you want to use fusion sensor data. Ensure all accuarcy are 3, or you will need to calibrte them.          ... View more
