Again, what is sd_app_evt_wait

[Paul]

I guess it puts the CPU into deep sleep mode and whatever interrupt will continue the code.

Is it possible to share any source code of this routine for better understanding what does sd_app_evt_wait do?

Thank you for a good answer Moloch. This is what it basically does. For deeper understanding check out the documentation for the developer.nordicsemi.com/.../a01075.html function
