检测到的信标大小不正确

Question

@Override
public void onBeaconServiceConnect() {
    BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);
    beaconManager.setRangeNotifier(new RangeNotifier() {
        @Override
        public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {

            Beacon.setHardwareEqualityEnforced(true);
            List<Beacon> beaconList = new ArrayList<Beacon>(beacons);

            if (beaconList.size() >= 2) {
                if (beaconList.get(0).getBluetoothAddress().equals("20:91:48:4C:5A:34") && beaconList.get(1).getBluetoothAddress().equals("20:91:48:4C:5B:AF")) {
                    if (beaconList.get(0).getDistance() < beaconList.get(1).getDistance()) {
                        Log.i("MainActivity", "You're in room 1");
                    }
                }
                if (beaconList.get(1).getBluetoothAddress().equals("20:91:48:4C:5A:34") && beaconList.get(0).getBluetoothAddress().equals("20:91:48:4C:5B:AF")) {
                    if (beaconList.get(1).getDistance() < beaconList.get(0).getDistance()) {
                        Log.i("MainActivity", "You're in room 1");
                    }
                }
                if (beaconList.get(0).getBluetoothAddress().equals("20:91:48:4C:5B:AF") && beaconList.get(1).getBluetoothAddress().equals("20:91:48:4C:5A:34")) {
                    if (beaconList.get(0).getDistance() < beaconList.get(1).getDistance()) {
                        Log.i("MainActivity", "You're in room 2");
                    }
                }
                if (beaconList.get(1).getBluetoothAddress().equals("20:91:48:4C:5B:AF") && beaconList.get(0).getBluetoothAddress().equals("20:91:48:4C:5A:34")) {
                    if (beaconList.get(1).getDistance() < beaconList.get(0).getDistance()) {
                        Log.i("MainActivity", "You're in room 2");
                    }
                }
            } else {
                Log.i("MainActivity", "Less than 2 beacons detected");
            }
        }
    });

每当我运行此代码并在线拥有2个ibeacons时，beaconList.size()应该为2，但是beaconList的大小为1，并且在日志中打印的输出为

beaconList.size()的大小应为2，因为我在线有2个ibeacons，而我确实有Beacon.setHardwareEqualityEnforced(true); 但是相反，大小是1，并且打印的信标少于2个，而您却在2号房间。这里似乎是什么问题？
