Android 蓝牙连接 - 服务发现失败 [英] Android Bluetooth Connection - Service Discovery Failed

问题描述

我正在尝试创建一个基本的蓝牙应用程序，用于测试设备.

I'm trying to create a basic bluetooth application, for testing the device.

我从 developer.android 得到了代码.这是链接:http://developer.android.com/guide/topics/connectivity/bluetooth.html#ConnectingDevices

I got the code from developer.android. Here is the link : http://developer.android.com/guide/topics/connectivity/bluetooth.html#ConnectingDevices

这是我的线程代码的运行部分:

Here is run part of my thread code:

     public void run() {

        mBluetoothAdapter.cancelDiscovery();
        Log.i(TAG, "Discovery Cancel!"); 

        try {
            Log.i(TAG, "Connection Started");
            mmSocket.connect();
            Log.i(TAG, "Connection Ended");
        } catch (IOException e) {
            try {
                Log.e(TAG, "Connection Failed", e);
                mmSocket.close();
            } catch (IOException e2) {
                Log.e(TAG, "Connection Close Failed", e2);
            }
            return;
        }

无论我尝试过什么 mmSocket.connect(); 都行不通.总是抛出一个 IOException 并且我从我的 logcat 得到那个日志:

Whatever I have tried mmSocket.connect(); never works. Always throws an IOException and I get that log from my logcat:

java.io.IOException:服务发现失败
在 android.bluetooth.BluetoothSocket$SdpHelper.doSdp(BluetoothSocket.java:403)
在 android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:213)

我看过这些文章，也试过写的东西，都没有解决我的问题.

I've looked at these articles, and tried the written things, none of them has solved my problem.

在 Android 上使用蓝牙的服务发现失败异常

无法在 Android ICS 上进行蓝牙连接

Android 蓝牙 java.io.IOException:连接被拒绝?

顺便说一句，我正在开发 android ics 4.0.4.

Btw I'm working on android ics 4.0.4.

我知道这不是设备问题，因为我已经在不同的设备上尝试过这个应用程序.

I know that is not device problem, cause I've tried this app on different devices.

推荐答案

我不知道，我仍然不明白 UUID 的东西，但问题是 UUID.我正在使用从内核日志中获得的 UUID，它是 00001105-0000-1000-8000-00805F9B34FB.

I don't know and I still don't understand the UUID stuff but the problem was the UUID. I'm using the UUID which I got from the kernel logs and it is 00001105-0000-1000-8000-00805F9B34FB.
