Android 无法连接到摩托罗拉Droid A855上的蓝牙

我正在使用Android 2.1 sdk和Motorolad Droid A855型号，当尝试连接到蓝牙（Socket SPP）时，根据logcat，我得到以下错误：， 并在socket.conect（）中获取异常抛出

这是我的密码

public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  out = (TextView) findViewById(R.id.out);

有人能帮我连接蓝牙吗？

知道发生了什么异常（确切地说）可能会帮助你找到问题的根源。但我无法在Mototola Droid A855中连接蓝牙，可以提供一些帮助。使用完全相同的代码，连接在2.1版本的三星I897上运行良好，在运行2.2版本的droid x上运行失败，在运行2.1版本的backflip上运行失败，在2.1版本的I100上运行失败，失败时的日志与下面发布的日志完全相同。所连接的设备没有区别。我已经在这个问题上纠缠了一段时间，还有典型的不兼容；(
