BNO055 Gyroscope Data is mixed up with Accelerometer

[sheejavarghese]

Hi,

I tried to read GyroZ( AA 01 18 02) , and AccZ(AA 01 0C 02) simultanuosly  and is continous polling every 100ms. After a certain period of of time  Gyro Data is mixed up with Acc Data. I am not able to distinguish between GyroZ data and AccZ data . How can I read Gyroscope and Accelerometer in same time?

Thanks in advance

Hello sheejavarghese,

Which mode you configured?

There was example code in github, you could refer it.

Hello sheejavarghese,

You could use reference code in github to read ACC, GYRO data.
