for (;;) { idle_state_handle(); }

Hi,

I wonder if the 

"for (;;)
{
idle_state_handle();

}" can add additional code. Because I don't see that happening in the examples.

What exampes are you talking about?

That function is usually located right above main() function, thus easy to locate and see what it does.

Note that you don't want to use the old SDK, look at the NRF connect SDK instead.
