title: uniqueliy identify Beacon on iOS and Android
body: <p>I have a little problem because I have to uniquely identify beacons on android and iOS. Currently I am using the mac Adress in android. I found out that many beacons (but not all) also show the mac adress in the advertisement data kCBAdvDataServiceData. So i checked the peripheral in iOS like this </p>
  
  <pre><code>func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
       let macAdress = advertisementData["kCBAdvDataServiceData"].debugDescription
       print(macAdress)
  }
  </code></pre>
  
  <p>this works for 27 out of 33 Beacons but not all. I also can't work with the UUID of the beacons because this value is not equal from iPhone to iPhone. Do you have any tips on how to identify a beacon in Android and iOS? </p>
  
  <p>Thank you for your help!</p>
