wenn mehrere iBeacon Sender, startRangingBeaconsInRegion Funktion nur erhalten eine UUID

Question

wenn ich startRangingBeaconsInRegion (neue Region ("myRangingUniqueId", null, null, null);) um das iBeacon-Signal in der Gegend, kann mein Code nur ein iBeacon bekommen signal, selbst wenn ich zwei oder drei iBeacon Sender im Raum aufstelle. Gibt es einen Fehler in meinem Code? oder vor stopRangingBeaconsInRegion kann die Ranging nur ein iBeacon-Signal bekommen?

mein Code:

private OnClickListener clickListener = new OnClickListener() { 
    @Override 
    public void onClick(View v){ 
     if (v.equals(ibeaconRecv)){ 
      TransmitTh transmitTh = new TransmitTh(); 
      ReceiveTh receiveTh = new ReceiveTh(); 
      NewReceiveTh newReceiveTh = new NewReceiveTh(); 

      transmitTh.start(); 
      //receiveTh.start(); 
      newReceiveTh.start(); 
     } 
    } 
};

Der Code muss statt nur Blick auf die ersten gefunden alle Baken iterieren. Dazu ändern:

if (beacons.size() > 0) { 
      patternFound = true; 
      double distance = beacons.iterator().next().getDistance(); 
      Identifier beaconUUID = beacons.iterator().next().getId1(); 
      Identifier beaconMajor = beacons.iterator().next().getId2(); 
      Identifier beaconMinor = beacons.iterator().next().getId3(); 

zu:

for (Beacon beacon : beacons) { 
      patternFound = true; 
      double distance = beacon.getDistance(); 
      Identifier beaconUUID = beacon.getId1(); 
      Identifier beaconMajor = beacon.getId2(); 
      Identifier beaconMinor = beacon.getId3();
