&lt;p&gt;There is no fixed limit on how many periodic advertisers you can be synchronized to. And it is possible to scan and do other activities at the same time. However,&amp;nbsp;there is a limit to how much RAM that can be assigned to each rol in the SoftDevice (64 kB). Also, with more concurrent roles/activities, the collisions will incerased, and these are handled according to the &lt;a href="https://docs.nordicsemi.com/bundle/ncs-2.4.3/page/nrfxlib/softdevice_controller/doc/scheduling.html#timing-activities_and_priorities"&gt;specified priorities&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Some problems about Periodic advertising</title><link>https://devzone.nordicsemi.com/thread/530732?ContentTypeID=1</link><pubDate>Mon, 07 Apr 2025 04:10:52 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:80d7e966-b22f-46e0-b8c9-e4518096c166</guid><dc:creator>Caesarzhou</dc:creator><description>&lt;p&gt;Yes,I want to know how to&amp;nbsp;&lt;span&gt;synchronize to multiple periodic&amp;nbsp;advertisers at the same time,and if&amp;nbsp; the scanner will keep the scanning mode or not when it switches the value to synchronous listening mode.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Some problems about Periodic advertising</title><link>https://devzone.nordicsemi.com/thread/530477?ContentTypeID=1</link><pubDate>Thu, 03 Apr 2025 14:12:45 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:a3537984-ac24-4667-bc76-41653b1221ef</guid><dc:creator>Einar Thorsrud</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;It is possible to continue recular scanning while being syncrhonized to a periodic advertiser. I am not sure I understand the full picutre here, though. Are you asking if you can synchronize to multiple periodic&amp;nbsp;advertisers at the same time? Or just about regular scanning while following a periodic advertiser?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
