Thank you for your support, there are no problems under simple testing.

Hi,

So we finally got to the culprit. 😃

The problem is that dk_buttons_and_leds.c does this little thing that when a button is pressed, it disables the interrupts, and manually scans the GPIOs to see when they are released. So if you are continuously pressing it, or even holding it down, there does not seem to be a release and interrupt is disabled.

So you can have a small workaround by introducing a check to prevent the system from going into sleep. I will attach the modified code here. THe check is named keep_alive.

Hope this helps. 🙂

Hi,

Apologies for the delay. I have not forgotten it. I was actually trying out the code and looking for a solution. I am having some doubts. I will discuss with experts and update you today with a response.

The problem can be reproduced by continuously pressing button1 for 2 minutes.

Hi,

It seems strange, as I am not able to reproduce this now. Maybe I am not understanding what you mean.

When trying with your earlier code, I was able to reproduce this. When the button 1 was pressed continuously, the device freezes and I had to force restart it. Is this what your problem is even now?

But in the modified sample that I shared, now pressing button 1 always helps. I'll attach the output:

When I press Button1, I get *** Booting Zephyr OS build v2.7.99-ncs1-1 *** always now.

After the device is powered on, press button1 on the DK continuously and quickly, and the device cannot be woken up after seeing that the log does not output. This problem must arise.
