Hi,

  i am working on power management for nrf52832. i used icm20948 for gyro and accelerometer. my battery capacity is less. so when my mcu is going to sleep but gyro and accelerometer in icm20948 is always on. 

so how can i switch off the gyro and accelerometer before my mcu going t sleep?

That is entirely a matter of the gyro/accelerometer - it has nothing at all to do with the nRF52832.

You need to study the gyro/accelerometer's documentation for details of how to control it.

If the gyro/accelerometer's documentation is unclear, you need to contact the manufacturer for support - it is nothing to do with Nordic.

Thank you for your reply.

  i change the register bank according to the datasheet of icm20948. but this not work.

please suggest more if you do that.

Again, you are in the wrong forum!

The icm20948 is not a Nordic product - so this is not the place to get support for it!

You need to go to the manufacturer for support - that is, Invensense.
