I am glad to hear that it worked. Please feel free to close this ticket at your convenience then.

I tried that pull request and it worked fine for us.

Thank you for all help.

You are right. That is the pull request that should fix the issue. Sorry I didn't inform you about earlier.

Since it is already merged, I can say that it's almost certain will be included in the next NCS release. However, I cannot comment on what that release would be, and when it would be. For that, you have to talk with your local sales manager contact.

Do you think you can cherry-pick that pull request and see if it helps?

I guess this is the pull request that fixes this: https://github.com/nrfconnect/sdk-nrf/pull/13133

Do you think it can be included in ncs 2.5.1?

That's good to know. I will keep the ticket open and inform here when a fix is released.

Thank you for the report.

It is not critical, since we have 2 buttons configured for wakeup. The chance of a user pressing both buttons during shutdown in minimal. We have also speeded up our shutdown tasks, so that there is less chance for the issue to happen on our device.

But a later fix will of course be welcomed :-)

Hi tellg,

I have gotten feedback from our team. The issue is indeed with the change to use sys_poweroff(), like you have pointed out.

sys_poweroff() will put the system int power-off right in place. Therefore, additional events, such as the button presses, were not processed.

The developers have registered the issue and will work on an alternative approach. I cannot comment on when that will be available though.

Is this issue critical for you now? If yes, is there any change in NCS 2.5.0 that you need, compared to 2.4.2?

Ah I see. That is a problem. I will follow-up with you as soon as I get any information.

I don't need wakeup to work at that point, but if buttonpress happens while powering down, then that button cannot wakeup the system anymore (device reset seems to be needed to fix this). I think the referenced code took care of that situation in ncs 2.4.0, but power down was modified in ncs 2.5.0 to use sys_poweroff, ref https://github.com/nrfconnect/sdk-nrf/commit/b6aa1ab2aae94c5e266c73ef5930d6893cb971d3

Hi tellg,

I have asked about this behavior change internally and will update you when I get any feedback. Do you mind sharing why you need the wakeup button to work before powering down is completed?
