我正在为我的MSc开发蓝牙应用程序。结束项目。它包括一个用
javame
实现的服务器和一个用
Android
编写的客户端

问题是Android
SDP
似乎无法识别我的JavaME服务器的
ServiceRecord

如果我在客户端中使用
BluetoothDevice.getUuids()
BluetoothDevice.fetchUuidsWithSdp()
方法,它们会返回一组
UUID
,但我的服务的
UUID
不在其中,因此我无法连接到它

这是
JAVAME
服务器示例的代码:

/*IMPORTS*/

public class StackOverFlowServer extends MIDlet {
    Display mDisplay;
    Form mForm;
    LocalDevice local;
    StreamConnectionNotifier server;
    ServiceRecord sr;
    String conURL;
    StreamConnection conn;
    public StackOverFlowServer() {
        mDisplay = Display.getDisplay(this);
        mDisplay.setCurrent(mForm);
        mForm = new Form(null);
        conURL = "btspp://localhost:68EE141812D211D78EED00B0D03D76EC;"

    }

    }

        try {

这是Android客户端的一部分:

package com.exampleproyect.stackoverflowclient;

import java.lang.reflect.InvocationTargetException;
import java.util.UUID;

import android.app.Activity;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.ParcelUuid;
import android.os.Parcelable;

public class StackOverFlowClientActivity extends Activity {
    BluetoothAdapter mBluetoothAdapter;
    BluetoothDevice C702;
    BroadcastReceiver mReceiver;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        C702 = mBluetoothAdapter.getRemoteDevice("00:23:F1:27:16:DA");
        C702.fetchUuidsWithSdp();
        mReceiver = new BroadcastReceiver() {
          @Override
          public void onReceive(Context arg0, Intent intent) {
              String action = intent.getAction();
              if (BluetoothDevice.ACTION_UUID.equals(action)){
                  Parcelable[] uuidExtra =                    intent.getParcelableArrayExtra("android.bluetooth.device.extra.UUID");
                  /*uuidExtra should contain my service's UUID among his files, but it doesn't!!*/
              }
          }
      };
      // Register the BroadcastReceiver
      IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_UUID);
      registerReceiver(mReceiver, filter1); // Don't forget to unregister during onDestroy
    }
}
最让我困扰的是,我的计算机可以正确地看到我的
JAVAME
服务器广告:

我做错了什么??:(为什么我的电脑的蓝牙可以在
JAVAME
中正确地看到我的服务广告,而Android却不能?
Android
可以通过蓝牙连接到
JAVAME
服务器

我在StackOverFlow阅读了大量其他类似的问题,但我还没有找到有效的解决方案(

我正在使用索尼爱立信C702(Java平台8)作为测试服务器,以及三星Galaxy S(ICS4.0.3,团队ICSSGS RC4.2)


EDIT1

我知道问题是什么

我希望JAVAME服务器使用UUID(例如):“68EE1418-12D2-11D7-8EED-00B0D03D76EC”发布我的服务,但代码似乎是:

        conURL = "btspp://localhost:68EE141812D211D78EED00B0D03D76EC;"
                + "authenticate=false;encrypt=false;name=MySampleApp";
        server = (StreamConnectionNotifier)
                Connector.open(conURL);
将默认串行端口服务UUID“00001101-0000-1000-8000-00805F9B34FB”添加为ServiceClassIDList atribute:

现在,有趣的是Android方法BluetoothDevice.FetchUUIDSWithDP(); 似乎获取默认的“00001101-0000-1000-8000-00805F9B34FB”UUID,而不是我的“68EE1418-12D2-11D7-8EED-00B0D03D76EC”UUID,使我的服务与手机的默认串行端口服务重叠

类似于中世纪的蓝牙网络扫描仪,它可以识别我的服务,但广告名为“00001101-0000-1000-8000-00805F9B34FB”:

如何删除
JAVAME
自动添加到我的服务中的额外
UUID

请帮忙,谢谢

EDIT2

好的,问题是索尼爱立信的手机。显然,它们插入了标准串行端口
UUID{0x1101}
在我定制的
UUID
之前,而三星和诺基亚手机则在我自己的服务记录后面插入此标准
UUID
。Android似乎只获取服务记录上属性
0x001
的第一个值,因此将我的服务与某些设备附带的默认串行端口混淆

因此,解决方案将是:

除了
ServiceClassID(0x001)
,当前的Android API还有什么方法可以获取更多的
servicecord
属性吗


是否有任何方法可以更新服务发现数据库(SDDB)中存储在“AcceptEndOpen”之后的
servicerecord
-JAVAME-已被调用?-我使用了
LocalDevice.updateRecord
SDDB
上创建服务后,它在模拟器上工作,但出现异常,在实际设备上不做任何操作。

找到解决方案了吗?我也有同样的问题
