What are the Low power mode for the nrf connect SDK

Hi,

Could you please guide on the modes for the low power mode which one is to select?

Requirement is when the particular gpio is low need to go to the low power mode and for come out of it gpio pin should be high.(interrupt for the detecting low and high)

Before entering into low power mode need to copy some data from ram to flash, all the peripherals should be off in low power mode and RTC should be ON always.Could you please suggest the suitable mode for the requirement

I have gone through the example code there i have tried the SYSTEM_OFF_MODE but at the time of exit it will do restart. We need the RTC keep running so any other mode is there which will not restart while exit from the mode ? Any example code where we can understand and explore the different mode? In the nrf52833 i can see only SYSTEM_OFF_MODE is there in power.c and there is lot many mode in zephyr (Standby, system to ideal ) can we use this modes for the nrf52833 if yes how i can achieve this?

I am using the nef connect sdk 1.9.1 version

Thanks.

  • I'm not aware of any example that doesn't go to System ON so you can just choose a SDK example you want to use.

    The scheduler will automatically enter the idle thread when there is no work to do, and this thread will make the chip enter System ON mode

    For instance, the idle thread will be entered if you call k_sleep() from your active threads.

    In the system on mode all the peripheral are inactive or we need to suspend them? 

    It depends on what peripherals you've enabled. I would recommend you try to measure the actual current consumption on your board first.
