https://devzone.nordicsemi.com/f/nordic-q-a/81093/queries-on-nrf52Hi support Team, Is there a way to make the nrf52840 to connect with only given MAC address (i.e., a MOBILE) ? The MAC address (i.e., a MOBILE) will be changed dynamically during the run time. The device should connect only to the latest given MAC addressen-USTelligent Community 13Wed, 27 Oct 2021 11:39:25 GMThttps://devzone.nordicsemi.com/thread/336180?ContentTypeID=1Wed, 27 Oct 2021 11:39:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6798ad2f-a3e3-484c-bf96-1a51b28dc8e2SwRa<p>Hi,</p> <p>You can use whitelist or directed advertising&nbsp;to achieve this if the nrf52840 has the GAP peripheral role. This will prevent other GAP centrals from connecting to it.&nbsp;You can refer the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/examples_ble_peripheral.html">ble_app_hids</a> examples in the SDK to do this. These examples enables both directed and whitelist advertisement modes.</p> <p>Regards,</p> <p>Swathy</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/336127?ContentTypeID=1Wed, 27 Oct 2021 08:43:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a51cfd84-1cab-4894-9b2b-fa0b75a2accbstark<p>Hi there,</p> <p>I&#39;m using Nrf5SDK</p> <p>Regards,</p> <p>Stark</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/336123?ContentTypeID=1Wed, 27 Oct 2021 08:34:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a1dd8ade-cc0d-4901-b079-90e2dc97709fSwRa<p>Hello,</p> <p>Could you tell me which SDK are you using?
