&lt;p&gt;have you made any progress or found a solution? I am very interested...&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Reduce channel sounding set up time.</title><link>https://devzone.nordicsemi.com/thread/550840?ContentTypeID=1</link><pubDate>Tue, 07 Oct 2025 17:33:55 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9d14130d-a3cd-40da-a618-55fc85230acd</guid><dc:creator>Triscuit</dc:creator><description>&lt;p&gt;Hi Amanda, I believe the difference is that I am trying to conduct sequential channel sounding rather than concurrent. I have got the system working for 3 reflectors, however, it is when I raise that number to 7 when it stops working. This is the question I am trying to wrap my head around. Because if I am doing sequential anyway, the number of reflectors should not affect the performance since the initiator is still only performing channel sounding with one reflector at a time. My suspicions are either there is now too much interference in the background, or that since I am storing a buffer for each individual reflector on the initiator, all the RAM is being used and thus leaving no space for the channel sounding procedure. Thank you so much for your time.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Sincerely,&lt;/p&gt;
&lt;p&gt;Triscuit&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Reduce channel sounding set up time.</title><link>https://devzone.nordicsemi.com/thread/550830?ContentTypeID=1</link><pubDate>Tue, 07 Oct 2025 15:06:37 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b3569e0b-49ea-409c-9c7c-27003d14a401</guid><dc:creator>Amanda Hsieh</dc:creator><description>&lt;p&gt;Hi,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;The issues you are experiencing are known limitations of the current channel sounding samples and stack support.&amp;nbsp;See&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/118844/nrf54l15-multipoint-channel-sounding-cannot-initiate-more-then-1-reflector/522924"&gt;this post&lt;/a&gt;.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
