Hello Jigar,

[quote userid="84586" url="~/f/nordic-q-a/54586/nrf52840-low-powermode"][/quote]

In Sleep I tried to disable UART. All I need is System ON mode and wake up using 1> Timer or 2> UART RX event.

Is it possible?

=> If you read the product Specification, section 5.3.4 - POWER ON mode, you will see that if you put your system in IDLE state, it is possible to make it run through Timer or UART Rx.

=> In section 5.3.3 - POWER OFF mode, it already said "The system is reset when it wakes up from the System OFF mode.".

I hope you find these information is useful.

Best regards,
