Hi,    https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bma456-ds000.pdf Please follow p11 ~13. You need to check below things. 1)  0x7D should be done before 0x7C.  2) Once initialization done, you should check 0x2A and get 0x01.    We have API to support BMA456 features as below.  https://github.com/BoschSensortec/BMA456-Sensor-API https://github.com/boschsensortec/BMA456-Sensor-API/blob/master/bma456an_examples/accelerometer/accelerometer.c Please check our API and use it.  Thank you.  ...
