The Peripheral can tell the Central that it would like a minimum connection interval of 30ms and a maximum of 200ms, but the Central can choose to ignore it and use whatever Connection Interval it wants.&nbsp;<br /><br />Can you share the sniffer trace?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/260002?ContentTypeID=1Wed, 15 Jul 2020 01:03:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88e904b9-0b9a-45eb-8225-39e14ef64f98Clever Huang<p>yeah，I have a log getted by sniffer. It show that the connection intervals&nbsp; are not&nbsp;<span>regular，include 30 ms（my nRF52840 set max connections interval ） or&nbsp; 200&nbsp; ms（my nRF52810 set max connections interval），sometimes，it&nbsp;</span>establish connection and then use&nbsp;<span>30 ms to transfer&nbsp;connection pack ， it always disconnected，but&nbsp;&nbsp;sometimes，it&nbsp;establish connection and then use&nbsp;200 ms to&nbsp;transfer&nbsp;connection pack，so is&nbsp; the connection interval depended on central or&nbsp;peripheral？</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/259959?ContentTypeID=1Tue, 14 Jul 2020 14:49:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:34e86b07-2930-45cd-8325-9b7e6274ab6ahaakonsh<p>What connection intervals are you getting?&nbsp;<br /><br />do you have a sniffer log?</p><div style="clear:both;"></div>
