Hi,
Inside BNO055 the magnetometer is actually BMM150 whose datasheet is avaialble online at https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmm150-ds001.pdf. The repetition number of xy and z axis of BMM150 means averaging how many times of the measurements to get final value to be placed in data registers. The higher repetition, the cleaner the data, of cause higher power consumption. In BMM150 datasheet we defined the preset of repetition as low power, regular, etc.
BMM150 has normal mode, forced mode, sleep mode and suspend mode. Normal mode with up to 30Hz ODR is continuous updating the data registers. Forced mode is upon request from the external host. After measurement is done, BMM150 goes to sleep mode from forced mode.
There is no difference between MAGOnly and ACCMAG because they all output mag raw data without calibration and sensor fusion.
Thanks.
