title: iOS Core Bluetooth peripheral scan question: how to distinguish multiple devices advertising at the same time
body: <p>We have multiple devices (same kind) advertising at the same time. But in iOS, all the advertising packets are treated as one device.
  Understand the reason: iOS filtered out the BLE address for privacy reasons. 
  Without BLE address the advertising packets from the difference devices are exactly the same.
  My question is: is it possible to use iOS core bluetooth to tell there are multiple devices are advertising?
  Thanks</p>
