I&#39;m wondering about why SoftDevice stays idle (in terms of radio operation) so &quot;long&quot; (&quot;t ScanReserved&quot; = 760 us) after channel changes during scanning? Despite that radio can switch for time of 40-120 us from one channel to the otheren-USTelligent Community 13Thu, 12 Oct 2017 11:21:01 GMThttps://devzone.nordicsemi.com/thread/101302?ContentTypeID=1Thu, 12 Oct 2017 11:21:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:efb52abf-f521-4b59-86ac-4da217ffa82bPetter Myhre<p>Yes, it needs more time, tScanReserved is the worst case time the stack needs in addition to the actual scan window.</p> <p>In this time scheduling of timing events, processing of potential radio traffic, switching/reconfiguring of radio hardware, and so on, is done.</p><div style="clear:both;"></div>
