https://devzone.nordicsemi.com/f/nordic-q-a/31201/12-5000-how-to-reduce-and-get-stable-connection-timeWe have set the peripheral ADV interval &amp; central SCAN interval as below configs, we found that the connection time is unstable, from 125ms to 980ms, we expect to get a stable connection time &lt; 200ms. Could you help to support how to achieve this goalen-USTelligent Community 13Wed, 07 Mar 2018 14:29:39 GMThttps://devzone.nordicsemi.com/thread/123271?ContentTypeID=1Wed, 07 Mar 2018 14:29:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a73b0478-9af8-465c-94b2-9e2b7f96dcbdFormerMember<p>The reason for the long connection setup time is&nbsp; that the advertising interval is a multiple the scan interval. When they are a multiple of each other, you risk that the advertiser &quot;always&quot; will advertise when the scanner isn&#39;t scanning. If they are not a multiple of each other, the relative timing between when&nbsp; the scanning and advertising will change, and thus the connection will be initiated faster.</p><div style="clear:both;"></div>
