Hi, Thanks for your inquiry. Please see the attached "Comparison chart between BMI055-BMI088 and BMI160-BMI270.pdf" for more information. For your application, gyro sensitivity needs to be calibrated to obtain accurate pitch and roll angles with your Kalman filtering. If you will calibrate your device one by one on a single-axis or tri-axis turn table, then you should use BMI088. Otherwise, you should use BMI270 because BMI270 has built-in gyro sensitivity calibration which is called CRT (component re-trim) feature. Thanks.

Hi, BME280 thermal resistance values are as below, Junction to case: θ~JC =46 C/W Junction to ambient: θ~JA =136 C/W Thanks.

Hi, Thanks for the update. The example code on the Github is ok without any issues. After soft-reset, the code brings BMI088 accel and gyro to normal mode. Then the code loads config file. After the config file is loaded successfully, the code starts to configure accel and gyro respectively. If loading the config file is at the end, then these accel and gyro configurations will be lost. Therefore, the example code is fine. Thanks.

Hi, We are able to reproduce the high BMI088 accel noise issue by following your code. And we found the root cause in your code. Basically you should place "bmi08a_load_config_file(&bmi088);" right after the "bmi08a_soft_reset(&bmi088);" and then configure the accel. Now you place "bmi08a_load_config_file(&bmi088);" at the end so that the accel configurations above will be lost or get reset. Therefore, the accel noise level is high. We have verified that once the load config file line of code is below the soft-reset line of code and above those accel configurations, the accel noise level is low. Thanks.
