我正在尝试将我的HTC myTouch 3G与蓝牙设备配对,蓝牙设备将通过SPP将数据传输到手机.我查看了聊天示例,发现它们缺少我需要的东西,因为我需要高数据速率,而Chat示例会在UI线程上阻塞.但这说我的主要问题是当我尝试连接当前未配对的设备时,蓝牙API会说如果设备需要配对代码,它会自动弹出一个对话框.这从未发生过.我如何确保它确实如此？这是我的代码……

BluetoothSocket btSocket;

String macAddress = data.getStringExtra("mac");

Log.d(TAG, "Found Device " + macAddress);

// Get the Bluetooth adapter on the device

BluetoothAdapter bta = ((MyApplication)this.getApplication()).getBtState();

BluetoothDevice btDevice = bta.getRemoteDevice(macAddress);

BluetoothSocket tmp = null;

try {

tmp = btDevice.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"));

} catch (IOException e) {

e.printStackTrace();

}

if (tmp != null) {

btSocket = tmp;

bta.cancelDiscovery();

try {

btSocket.connect();

} catch (IOException e) {

try {

Log.e(TAG, "------------- Close IOException");

btSocket.close();

} catch (IOException e2) {

Log.e(TAG, "unable to close() socket during connection failure", e2);

}

}

}

这也是我得到的错误：

关于这个似乎是一个错误的一个奇怪的事情是,如果我运行此代码并且它失败,那么我关闭蓝牙并在设备上将其重新显示为在堆栈中配对.根据我的理解,myTouch上的蓝牙芯片是2.1,我们尝试连接的芯片是1.2
