nRF52840 Low powerMode

[Jigar]

Hello,

I am using System ON mode for low power. Still it is consuming 2mA. I heard i can go down to 60uA. I am using UART for Communication. 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?

Another question, In Deep sleep mode, How do I use GPIO to wake up without Resetting?

Any example?

Thanks

Jay

=> 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.
