If you use this by default, and only starts advertising without whitelist when the user presses a button, you should be able to achieve what you need.</p> <p>Almost all the SDK examples use a whitelist, for example the ble_app_proximity.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3505?ContentTypeID=1Mon, 21 Oct 2013 20:21:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:beb738a5-408c-4eb6-8445-ab73c44a2abesyntroniks<p>Are you sure you need pairing instead of a plain connection? You may be able to use directed advertisement packets to request the master to connect to you then use the &#39;just works&#39; method of pairing (which is a passkey of 000000 if I remember correctly)</p><div style="clear:both;"></div>
