Android的蓝牙：软件导致连接中止 [英] Android Bluetooth: Software Caused Connection Abort

问题描述

我收到例外，每当我试图与Android设备连接到bluettoth功能的设备，它连接和withina夫妇一分钟是越来越异常。 要使用BLuettoth设备（SPP配置文件），我使用的连接

I am getting exception whenever I am trying to connect with android device to bluettoth enabled device, it is connecting and withina couple of a minute it is getting exception. To connect using BLuettoth device(Spp profile), I am using

Method m;
m = mmDevice.getClass().getMethod("createRfcommSocket",
new Class[] { int.class });

tmp = (BluetoothSocket) m.invoke(mmDevice, 1); 

使用这个code，我能够连接到该设备。但在这一行字节= mmInStream.read（缓冲区），我得到异常withina夫妇的分钟。我可以使用

Using this code, I am able to to connect to the device. But at this line bytes = mmInStream.read(buffer), I am getting exception withina couple of a min. I can use

if(mmInStream.available() > 0) {
bytes = mmInStream.read(buffer);
} 

但是，如果我把条件这里，它不能理解设备是否仍连接或不与其他设备。监守异常不会发生。 我无法找出解决方案，并试图为2天。但我不能找到解决办法。

But if i put the condition here, it can't understand whether device is still connected or not with other device. Becuase exception will not be occurred. I couldn't find out the solution and tried for 2 days. But I couldn't found the solution.

你能帮帮我吗？

在此先感谢

推荐答案

我有同样的问题与蓝牙播出后启动服务器。解决的办法是发送一个字节后，服务器建立通过BluetoothServerSocket.accept连接（）。 BluetoothSocket.connect（）一个字节后，客户端读取。所以两端处于同步

I had the same problem with a server which started after a bluetooth broadcast. The solution was to send a byte after the server established a connection via BluetoothServerSocket.accept(). The client reads after BluetoothSocket.connect() one byte. So both ends are in sync.
