Un poco atascado aquí, podría necesitar tu ayuda. Quiero leer varias características de BLE a la vez, algunas personas sugieren usar PriorityQueue para eso. Ya conozco todos los fluidos, etc. solo necesito una forma de leer varios a la vez. ¿Alguien podría explicar cómo debería ser exactamente? ¿O tal vez hay otra solución más fácil?

Gracias de antemano, aquí está mi código:

public static final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {

    PriorityQueue<BluetoothGattCharacteristic> queue = new PriorityQueue<BluetoothGattCharacteristic>();

    // When connection state changes
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            Log.v(TAG, "Connected!");
            gatt.discoverServices();
        }
        if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            Log.v(TAG, "Disconnected...");

        }
    }

    @Override
    public void onServicesDiscovered(BluetoothGatt gatt, int status) {

        List<BluetoothGattService> services = gatt.getServices();
        BluetoothGattService rightService = null;

        for (int i = 0; i < services.size(); i++) {
            if (services.get(i).getCharacteristics().size() > 8) {
                rightService = services.get(i);
            }
        }

        List<UUID> uuidsList;

        UUID TRANSMISSION_POWER = rightService.getCharacteristics().get(4).getUuid();
        UUID BROADCASTING_INTERVAL = rightService.getCharacteristics().get(6).getUuid();
        UUID BEACON_NAME = rightService.getCharacteristics().get(8).getUuid();
        UUID CONNECTION_MODE = rightService.getCharacteristics().get(9).getUuid();
        //UUID SOFT_REBOOT = rightService.getCharacteristics().get(10).getUuid();

        uuidsList = new ArrayList<UUID>();

        uuidsList.add(TRANSMISSION_POWER);
        uuidsList.add(BROADCASTING_INTERVAL);
        uuidsList.add(BEACON_NAME);
        uuidsList.add(CONNECTION_MODE);
        //uuidsList.add(SOFT_REBOOT);

        queue.add(rightService.getCharacteristic(uuidsList.get(0)));
        queue.add(rightService.getCharacteristic(uuidsList.get(1)));
        queue.add(rightService.getCharacteristic(uuidsList.get(2)));

    }

    @Override
    public void onCharacteristicRead(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) {

        Log.v(TAG, "CHARACTERISTIC VALUE___: " + characteristic.getIntValue(BluetoothGattCharacteristic.FORMAT_UINT8, 0));
        onServicesDiscovered(gatt, 0);

    }

};

ACTUALIZAR:

incluso después de ponerlos en diferentes hilos, solo reacciona a un gatt.readCharacteristic (...). como el siguiente:

// Gatt Callback
public static final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {

    // When connection state changes
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            Log.v(TAG, "Connected!");
            gatt.discoverServices();
        }
        if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            Log.v(TAG, "Disconnected...");

        }
    }

    @Override
    public void onServicesDiscovered(BluetoothGatt gatt, int status) {


        List<BluetoothGattService> services = gatt.getServices();

        /*
        DISPLAY ALL SERVICES AND CHARACTERISTICS

        for (int i = 0; i < services.size(); i++) {
            Log.v(TAG, "SERVICE____: " + services.get(i).getUuid());

            for (int k = 0; k < services.get(i).getCharacteristics().size(); k++) {
                Log.v(TAG, "CHARACTERISTIC____: " + services.get(i).getCharacteristics().get(k).getUuid());
            }

        }
        */

        BluetoothGattService rightService = null;

        for (int i = 0; i < services.size(); i++) {
            if (services.get(i).getCharacteristics().size() > 8) {
                rightService = services.get(i);
            }
        }

        List<UUID> uuidsList;

        UUID TRANSMISSION_POWER = rightService.getCharacteristics().get(4).getUuid();
        UUID BROADCASTING_INTERVAL = rightService.getCharacteristics().get(6).getUuid();
