Hello Jagath,
There are two alogirhtms we offer.
We can check it page 43 in our bma400 datasheet.
https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bma400-ds000.pdf.
Accuracy could vary because of your bma400 location and test condition.
However, if you want more sensitive algorithm, please use "non-wrist" and if you want not sensitive algorithm, please "wrist".
From my side, accuracy is for non-wrist is around 97~8%, but not official data.
Thanks,
