&lt;p&gt;Unfortunately, our sniffer don&amp;#39;t support sniffing on secondary channels.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF51 sniffer dongle not capturing secondary channels</title><link>https://devzone.nordicsemi.com/thread/320055?ContentTypeID=1</link><pubDate>Wed, 14 Jul 2021 13:52:46 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ba4f9afc-2c8f-49fd-b140-1fa444d346cf</guid><dc:creator>GowthamPV</dc:creator><description>&lt;p&gt;Hi &lt;a href="https://devzone.nordicsemi.com/members/mttrinh"&gt;Mttrinh&lt;/a&gt; &lt;a href="https://devzone.nordicsemi.com/"&gt;Nordic DevZone&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Is there any nordic product / board which we can use as sniffer to sniff secondary channels?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF51 sniffer dongle not capturing secondary channels</title><link>https://devzone.nordicsemi.com/thread/319474?ContentTypeID=1</link><pubDate>Sat, 10 Jul 2021 11:56:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:3398a244-7bd1-4149-9c0f-9dfb357dec8d</guid><dc:creator>Mttrinh</dc:creator><description>&lt;p&gt;Hi,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;No, you won&amp;#39;t be able to capture secondary channels, the sniffer&amp;nbsp;&lt;span&gt;only scans the three primary advertising channels (37, 38, and 39).&lt;/span&gt;&lt;/p&gt;
[quote user=""]Is it possible to configure nRF51 sniffer application to additionally sniff packets from specific data channel ? (Like channel 31)[/quote]
&lt;p&gt;So by default the sniffer will hop between channels 37,38 and 39. If you want the sniffer to only capture packets from only one of the primary channels, I think in the nrf sniffer interface you can change the values in &amp;quot;Adv Hop&amp;quot; to for example 37, 37, 37.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
