Выходной поток Android BluetoothSocket пишет слишком медленно

По сути, я работал над беспроводной мышью, которая использует Bluetooth или Wi-Fi. У меня все работает, включая чтение и написание сообщений. Однако скорость передачи данных через Bluetooth слишком мала для компенсации. Я посмотрел повсюду, и я не могу понять, что вызывает эту скорость. Я использую выделенный поток для выполнения всех операций записи.

Вот мой код ConnectedThread (почти точно такой же, как в примере Android SDK)

package com.tutorials.jurko.androidmouse;

import android.bluetooth.BluetoothSocket;
import android.net.ConnectivityManager;

import java.io.BufferedOutputStream;
import java.io.IOError;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

/**

public class ConnectedThread extends Thread {
    private final BluetoothSocket mmSocket;
    private final InputStream mmInStream;
    private final BufferedOutputStream mmOutStream;
    public static int count = 0;

    public ConnectedThread(BluetoothSocket socket) {
        mmSocket = socket;
        InputStream tmpIn = null;
        OutputStream tmpOut = null;

        try {
            tmpIn = mmSocket.getInputStream();
            tmpOut = mmSocket.getOutputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }

        mmInStream = tmpIn;
        mmOutStream = new BufferedOutputStream(tmpOut);
    }

    public void write(Byte[] bytes) {
        count++;
        try {
            byte x = bytes[0].byteValue();
            byte y = bytes[1].byteValue();
            System.out.println("Count: " + count);
            byte buf[] = {x, y};
            mmOutStream.write(buf);
            mmOutStream.flush();

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Вот мой код сервера (прием сообщений)

import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import javax.bluetooth.UUID;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;
import javax.microedition.io.StreamConnectionNotifier;
import java.awt.*;
import java.awt.event.InputEvent;
