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
