nrf52840 System ON Low power mode.

Hello,

I am new in nordic previously I was working on Cypress controllers. I am trying to put the device in System ON Low power mode.

I have tried the below functions but there is not any effect on current consumption.

To make sure it will always be in an idle state, I am not doing anything in the main function is empty like below. But I am getting current consumption of around 430-440uA. When I remove cpuidle() function call then also current consumption remains the same.

void cpuidle(){
while (true)
{
k_cpu_idle();
}

}

void main(void)
{
cpuidle();
}

Also I have tried below function but I am getting undefined reference to `sd_app_evt_wait' error.

sd_app_evt_wait();

Please let me know am I doing anything wrong?

Thanks in advance.

Regards,

Neeraj Dhekale
