I currently have some services and characteristics. I have mobile applications and I connect to my device and transfer data. I do not do pairing.

That the user have to physically interact with the device in order to connect.&nbsp;</p> <p>You could set up a timer to start/stop advertising, but I assume that it would be hard to time when to start/stop the advertising if you don&#39;t know exactly when the device needs to be available to connect.&nbsp;</p> <p>Br,&nbsp;<br />Joakim</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/431620?ContentTypeID=1Sun, 18 Jun 2023 21:20:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:952f07bd-2696-410e-8ce6-edaad325f566Coderprofile<p>Currently, I do this with a button, but encouraging to press a button when the mobile application is opened is not a very good option for the user experience. <br /><br />I was actually researching to see if I could find a better method. <br /><br />Thank you for your valuable information.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/431618?ContentTypeID=1Sun, 18 Jun 2023 21:16:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:43885de9-9c48-44e7-a3a3-e687cb1e37b1Joakim Jakobsen<p>Hi.&nbsp;</p> <p>The power consumption while advertising will not improve even if the devices are paired/bonded.&nbsp;</p> <p>Is there a reason that you can&#39;t stay connected with the device? So that you don&#39;t have to advertise indefinite.&nbsp;</p> <p>If you want to reduce the power consumption you could try to find a solution where the peripheral only starts advertising when you need to connect.&nbsp;</p> <p>Br,&nbsp;<br />Joakim</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/431616?ContentTypeID=1Sun, 18 Jun 2023 20:52:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fccaa6eb-b0ec-459a-90aa-8662f49c6064Coderprofile<p>Hi, Thank you,<br /><br />So is it useful to make a&nbsp;pairing here?<br />Can we reduce power consumption when we advertise when there is pairing?</p> <div id="gtx-trans" style="left:376px;position:absolute;top:63.4px;"> <div class="gtx-trans-icon"></div> </div><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/431615?ContentTypeID=1Sun, 18 Jun 2023 20:50:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3854a8ed-4d5c-416c-ab2a-955c45b74d99Joakim Jakobsen<p>Hi.&nbsp;</p> <p>Unfortunately no.
