MPU9250 wake on motion interrupt configuration

By saisusmith , 29 January 2019

Hi Invensense,
I am trying to implement wake on motion interrupt configuration for MPU-9250.i am starting a timer in main.c file for 60 seconds and within this 60 seconds if there is no motion from MPU-9250 iam keeping 9250 in low power accelerometer mode in 60 seconds timer expiration handler..I am able to put the MPU-9250 in low power accelerometer mode and after that when I wave or shake my board no wake on motion is being seen i.e., wake on motion interrupt is not being triggered.I did the wake on motion configuration according to the flow chart specified in the MPU-9250 datasheet.

Kindly please help me out on this issue ASAP as it's urgent for me.

Thanks and Regards,
Susmith
