Galaxy s6 Android LL: onConnectionStateChange вернуть мне 133 Статус ошибки

Question

Я разработал приложение, которое должно переподключаться к серверному приложению, установленному на определенном устройстве. Я протестировал свое приложение на каком-то устройстве, но на galaxy s6 с Lollipop у меня возникли некоторые проблемы.

Это комбинация:

client (peripherall) is installed on galaxy tab 10.1 kitkat 
server (central role) is installed on galaxy s6 with lollipop 
ok

client (peripherall) is installed on galaxy nexus 6 lollipop
server (central role) is installed on galaxy s6 with lollipop 
ok

client (peripherall) is installed on galaxy s6 lollipop
server (central role) is installed on galaxy nexus 6 with lollipop 
not working

На последней комбинации функция соединения возвращает мне 133 статуса.

Это мой код:

public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
    super.onConnectionStateChange(gatt, status, newState);
    Log.d("connect", "status = " + status + " newState = " + newState);
....

В чем разница между Киткат и Леденец? Нужно ли обрабатывать соединение по-другому?

public void new_automatization() {
    automatizationInProgress = true;
    Log.d("connect","new auto: si parte");
    this.init();
    Bluetooth.getMe().stopScan();
    final String MACaddress=getDataFromPreferences("address");
    final String keycode=getDataFromPreferences("unlockcode");  

    if(!Bluetooth.getMe().isScanning()) {
        Bluetooth.getMe().startScan(new Bluetooth.ScanCallback() {
            boolean deviceIsFound = false;

            @Override
            public void onDeviceFound(final BluetoothDevice device, int rssi,byte[] scanRecord) {
                Log.d("testAlpha","dentro onDeviceFound");
                if(device != null) {
                    String address=new String();                    
                    if(device.getName() != null) {  
                        Log.d("testAlpha","trovato name: "+device.getName()+"mac: "+device.getAddress());
                        address=device.getName();
                        if(address.equals(MACaddress)) {
                            Log.d("testAlpha","mi connetto a: "+device.getName()+"mac: "+device.getAddress());
                            Bluetooth.getMe().stopScan();//possiamo riconnetterci
                            deviceIsFound=true;
                            setDevice(device);
                            unlock(keycode);
                            automatizationInProgress = false;
                        }
                    }
                } else {
                    Log.i("connect","dentro onDeviceFound null");
                    search_ended=true;
                    sendMessage(DEVICE_NOT_FOUND);
                    automatizationInProgress = false;
                }   
            }
        });
    }
}

Это функция начального и конечного сканирования:

        }
    }

и в unlock() Я называю функцию подключения.

PS: имя устройства, к которому я хочу подключиться (nexus 6), находится в переменной macaddress.
