This is typically used in HID devices, where it is important to have a really quick reconnect if the mouse or keyboard disconnects due to noise or packet loss, so that the used doesn&#39;t realize that the disconnect occured.</p> <p>However, if the central doesn&#39;t scan for the directed advertisements, there isn&#39;t really much to do about it.&nbsp;</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
