环境：
开发：WPF + PC（windows 7）
客户端：PC（windows 7）
远程蓝牙设备：华为荣耀4C
蓝牙库：32feet.net
BluetoothClient localClient;
1. 查找设备完成
2. 配对完成
3. 连接远程设备：
BluetoothEndPoint ep;
// 第二个参数只有选择BluetoothService.Handsfree才能连上远程蓝牙设备
ep = new BluetoothEndPoint(mSelectDevice.DeviceAddress, BluetoothService.Handsfree);
//ep = new BluetoothEndPoint(mSelectDevice.DeviceAddress, BluetoothService.SerialPort);
localClient.BeginConnect(ep, new AsyncCallback(RemoteDeviceConnect), localClient);// 使用异步方式连接
private void RemoteDeviceConnect(IAsyncResult result)// 异步连接完成
{
BluetoothClient client = (BluetoothClient)result.AsyncState;
if (client.Client.Connected)// 刚进来时Connected为true，调试过程停在这（断点）过了5秒左右变成false
{
mNetworkStream = client.GetStream();
mRevThread = new Thread(BT_DataReceive);
mRevThread.Start();
}
}
代码还未实现断开连接，为什么刚进入RemoteDeviceConnect方法时client.Client.Connected为true，debug停在这5秒左右就变成false？
