The Peripheral link events are arbitrarily scheduled with respect to each other. Therefore, if one link event ends too close to the start of a peripheral event, the notification signal before the peripheral connection event might not be available to the application.
Radio Event distance too short to trigger the notification signal shows an example where the gap before Link-3 is too short to trigger the nACTIVE and ACTIVE notification signals.
Figure 1. Radio Event distance too short to trigger the notification signal
As shown in Radio Event distance is long enough to trigger notification signal, the notification signal will arrive if the following condition is met:

tndist
In the figure, the gap before Link-3 is sufficient to trigger the nACTIVE and ACTIVE notification signals.
