You can in addition add some application specific data in the payload to identify the advertisers you want your app to connect to. In iOS the different peripherals are identified to the app with an UUID and the address itself might be hidden from the developer. So the manufacture specific data would be a better way for your app to identify your peripherals.</p><div style="clear:both;"></div>
