regarding sd_power_system_off

[DH.Yoon]

Hi,

I looked at this comment.

If this function (sd_power_system_off) is executed, can I wake up the device again with a soft reset?

If not,

What is a function that can wake up with a soft reset?

My custom board does not have a reset button.

Hi Yoon,

You can use GPIOTE to wake up device from power off state.

The simplest way to wake up the device is just add one physical button which it connected to GPIO.
then configure that GPIO to input mode with event trigger.

Here is simple example for this case.

Thanks,
Eugene
