&lt;p&gt;Sorry I don&amp;#39;t remember exactly what I did but I think I just updated and downloaded all the zephyr dependencies from the terminal, it took like 10 minutes to download. It was basically just a bunch of trial and error. Although at the end I did not see that big of an improvement in accuracy compared to the version without real-time ranging.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Channel Sounding With Real Time Ranging Fails To Build</title><link>https://devzone.nordicsemi.com/thread/537500?ContentTypeID=1</link><pubDate>Fri, 30 May 2025 09:59:01 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ab4bf14c-6f09-4d4e-b686-d600352c6ce4</guid><dc:creator>OilyMacaroni</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
