Then you can use either whitelisting or directed advertising to filter what device to connect to. See for instance the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v11.0.0%2Flib_ble_advertising.html&amp;cp=4_0_0_3_1_1_1&amp;anchor=whitelist">advertising module</a> or the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v11.0.0%2Flib_peer_manager.html&amp;cp=4_0_0_3_1_11">peer manager</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50130?ContentTypeID=1Sat, 23 Apr 2016 18:23:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d22e92e7-fa75-40c1-b3d5-74ca783f3736Pomah9i<p>I understand how to do it, thanks! I now have a question. How to make the Board able to connect the phone with a specific mac address of bluetooth module.

If so, yes it is possible.</p> <p>Any further details would be great, as it would make it easier to give good answers.</p><div style="clear:both;"></div>
