AsycnSocket无法通过WiFi连接到TCP串行端口

我有一个iPhone应用程序，我在模拟器上运行。 XCode ver 3.2.6/4.3。我试图通过无线网络与个人电脑串口上的收音机进行通信，无论是在同一台服务器上...我试过NSStream和GCDAsyncSocket（只是为了确保）。收音机有自己的IP地址和端口号。它实际上是一个TCP/IP wifi模块。在改变PC上的远程访问接受我的IP地址之后，我终于可以连接了，但是我立即就开始了，我假设这是在我尝试读取或写入时。使用Telnet时，连接然后断开连接也会发生同样的情况。当有人连接时，收音机发出HELLO，所以Telnet必须在发送数据后尝试读取。我正在猜测。我以为我能够连接，我应该能够读/写。（是的，新手在这里）AsycnSocket无法通过WiFi连接到TCP串行端口

我会很感激任何想法或方向。我一直在研究一个多星期，并去疯狂。

谢谢。我添加了下面的代码以及错误消息。

这是错误消息： socketDidDisconnect：withError： “错误域= NSOSStatusErrorDomain 代码= -9844” 该操作不能完成。（OSStatus误差 -9844。） “的UserInfo = 0x4c38a60 {}”

我想你应该添加一些代码来举例说明它 – ppaulojr
