Hi, i am using nrf51822 interface with mpu9250 and i want to detect a tap without using of DMP feature of mpu motion sensor. my application requirement is low current consumption that's why i want to play with raw readings of mpu and want to detect a tap or double tap. how can i achieve this.does anybody has idea about this? immediate help nedded!!

Hi, I think you should ask this at InvenSense, the manufacturer of MPU series.

As far as I know, you can configure the MPU to toggle a GPIO interrupt for free fall, data ready, etc events.

In short, this question is not related to nRF series.

Check the interrupt events of the MPU or contact the InvenSense team.

Since you have a successful interface between the nRF51 and the MPU, the event configuration will be easy for you.
