Hello, Regarding using BMM150 as BMI160 AUX data, you can find it below url. https://github.com/BoschSensortec/BMI160_driver/wiki/How-to-use-an-auxiliary-sensor-or-magnetometer-with-the-BMI160 However, github code doesn't update for latest BMI160 BMM150 api, so please check the attached file. Then, you can compare it with your configuration. If you need to debug, I'd like to suggest checking rslt value which has return value for bmi160 or bmm150. If the rslt value has some negative value, it means there is some issue function inside. Thanks, Minhwan Oh
