nRF52832 not enter into system ON mode.

Dear Team,

SDK - sdk version 15.0.0
IDE - Segger Embedded Studio
SOFTDEVICE - s140_nrf52_6.0.0_softdevice

We are developing our custom application and it is battery operated device. So we want low power consumption in idle condition. For low power we are using system ON mode. we are using switch in polling method.

I have disabled all the peripherals in system ON mode. 

The problem is that in system ON mode when I disabled app uart then device is not waking up using switch and power consumption is low around 90 microamps.

One more thing if I do not uninit app uart then device wakes up properly and power consumption is around 2 mA.

If I configure the switch as interrupt and uninit app uart every thing is working fine and power consumption is also low around 90 microamps.


I do not know how to resolve the issue.

Please give some solution as quickly as possible.
