what does the API sd_app_evt_wait() do?

[DevineFelix]

hi. As the manual says,It waits for an application event. and is called in the main while loop. Does it mean that if I put some other routines carrying out polling function into the main while loop, they will be blocked by sd_app_evt_wait() if it does not encouter any event for a long time? thank you.

Yes - if the sd_app_evt_wait() is in your polling code then it will stop at that point until an event occurs.

Which events? Are the bluetooth events application events? There has never been a terminology so confusing to me as 'application' event. I write the application, so it would seem I would define these events. But that is not the case. Are all events sent up to the application by SoftDevice application events? Someone please answer that basic question!
