title: bluetooth low energy advertising packet and topology
body: <p>I want to advertise a single id lets say "stackoverflow1" on a ble device. So people close to the sensor can get this message (welcome to wwdc2012) as popups on the iPhone. That's it! meaning that there is no update on the value or anything else in other words I just want to know which room I came in. In another room there's another sensor adversing "stackoverflow2".</p>
  
  <p>Now the question is, should I put the rooms' sensor (advertiser) as Peripherals and visitors' iPhones as Centrals?</p>
  
  <p>If your answer is yes, can I send this Id in advertising packet? i.e. can I skip connection to the room's peripheral? Please guide me a little but on this</p>
  
  <p>Thanks</p>
