    Hello Mark, 

     

    Firstly, all user configuration setting to be overwritten with their default value after softreset and the sensor goes to enter normal mode. 

    Please check p44 in our datasheet. 

    https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bma280-ds000.pdf

    And, if you want to use our FIFO, I'd like to use our reference example code as below url.

    Thank you.
