When timing events overlap only one of them will run while the others are dropped entirely.</p> <p>What you see is one scan event being dropped when an advertising event is successfully scheduled. It leaves a break in scanning corresponding to one scan interval.</p> <p>What event to run and what event to drop is decided as documented in <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s132.sds%2Fdita%2Fsoftdevices%2Fs130%2Fmultilink_scheduling%2Fpriorities_and_events_intro.html">SoftDevice timing-activities and priorities</a>.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
