Android的蓝牙连接 - 服务发现失败

问题描述

我试图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code。这里是链接：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

下面是运行我的线程code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;
        }

无论我都试过 mmSocket.connect（）; 永远不会奏效。总是抛出IOException，我得到的日志从我的logcat：

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

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

java.io.IOException: Service discovery failed
at android.bluetooth.BluetoothSocket$SdpHelper.doSdp(BluetoothSocket.java:403)
at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:213)

我已经看了这些文章，并尝试了书面的东西，没有人已经解决了我的问题。

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

Android蓝牙：服务发现失败，连接到台式机/笔记本电脑

Service发现在Android

Bluetooth在Android ICS不可能连接

Android蓝牙java.io.IOException异常：连接被拒绝

顺便说一下我的工作在Android上的IC 4.0.4。

Btw I'm working on android ics 4.0.4.

我知道这不是设备的问题，因为我已经尝试了不同设备上的这个程序。

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

推荐答案

我不知道，我还是不明白的UUID的东西，但问题是UUID。我用这是我从内核日志中得到了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.
