Sleep and wake nrf52832 with icm20948

[Uttkarsh Tak]

Hi!
I am using nrf52832 with icm20948 (SPI) and I want to put nrf52 in sleep and wake up if there's any motion detected. I am unable to put my device on sleep by the function sd_app_evt_wait(); although sd_power_system_off(); puts the device in off mode but i am unable to turn it on using nrf_gpio_cfg_sense_input(1, NRF_GPIO_PIN_NOPULL, NRF_GPIO_PIN_SENSE_HIGH);

Kindly help me to get my device to sleep when not in motion and wake it up by any motion detected.

Show how you tried to do that.

How do you determine that it's not going to sleep?

How to post source code:

I checked the current consumption using a multimeter and the value was in mili amps, when put in deep sleep/system OFF i did get a low current value. I am trying wake_on_motion to reduce the current consumption since my application requires a battery.
