Hi,
BNO055 can enter low power mode when no-motion interrupt happens. By default no-motion interrupt will be generated if BNO055 accelerometer measurements are within the threshold of 0x0A * 7.81mg = 78.1mg @+/-4g range for more than the amount of duration of 5s. Please refer to page 94 of BNO055 datasheet.
BNO055 can enter normal mode again from low power mode if any-motion interrupt happens. By default any-motion interrupt will be generated if BNO055 accelerometer measurements are more than the AM threhsold of 0x14 * 7.81mg = 156.2mg for more than the number of data points of (3 + 1 = 4) AM_DUR. Please refer to page 92 and 93 of BNO055 datasheet.
Thanks.
