BMM150+BMI160 rawdata is not matching with BMM150+BMI270

Hi BSTRobin,

Thanks for sparing your time to validate this.

If you check in your logs the rawdata of accel, gyro and Mag has a lot of difference. 
As you already have the setup, can you try to test by keeping both of them in same position and compare the rawdata.

The accel and gyro data of BMI270 is way high when compared to BMI160, this should be similar in same position.

Can you validate with accel range 16G and Gyro range 2000.

Thankyou once again

Hi

Can you confirm whether it is possible to achieve similar raw data x,y,z values for both BMI160 and BMI270.? Wrt that we will check what all changes are required from algo side.

Thanks

Hello Santhosh_N,

I set ACC to 16G and GYRO to 2000dps range. The following were test result.

If you only see MAG RAW data of BMI160 and BMI270, there is difference. After Compensation, MAG data didn't have big difference.

BMI160 + BMM150

BMI270 + BMM150

Thanks Robin.

From the above the logs, I understand the raw data can't be similar for BMI160 and BMI270. All these days i am trying to get them same which is required for my project.

Is my understanding correct,
1.Rawdata can't be equal for BMI160+BMM150 and BMI270+BMM150. ?
2.To calculate the other parameters using this rawdata, the compensation and algo are different for them.?
