All of our SoftDevices support this procedure completely.</p> <p>The new feature in 4.1 where this is done on the host side, and where the peripheral can initiate the procedure (not just request it) is currently not supported.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/26054?ContentTypeID=1Sun, 31 May 2015 02:06:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cd7e2f21-010b-440f-9400-416d4c660128wuvo.leo<p>yes,about connection parameter update procedure,Thanks again!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/26053?ContentTypeID=1Sat, 30 May 2015 15:21:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:420b99d7-9a44-4352-8d5f-297666765875Ulrich Myhre<p>I think you have to clarify this question a bit. What kind of parameters are we talking about? Do you mean connection parameter update procedure? Connection parameter request? Feature exchange (security)?</p><div style="clear:both;"></div>
