C ++ WinSock蓝牙连接 – AT命令 – 收到错误

这是这个问题的延续: https : //stackoverflow.com/questions/37020491/programming-for-bluetooth-in-winsock-a-solution-needed

我在C ++中不强大!

这里可以findLib / Header文件C:\ Program Files(x86)\ Windows Kits \ 8.1 \ Include \ um这里是Windows SDK工具包的一部分: 用于Windows 8.1的Windows软件开发工具包(SDK)或Windows软件用于Windows 10的开发工具包(SDK)

有人能够告诉我哪里出错了,我正试图发送和接收蓝牙GSM设备的AT命令。 这是一个三星Ace。

我不断收到'错误'返回。 否则,该命令返回“OK”…,然后返回“ERROR” – 但是所有的AT命令都会以'ERROR'

我已经尝试了几个UUID GUID。

我的输出是这样的:

 ****************************************************** WINSOCK: 'WSAData' Return Code: 0 Local EndPoint Address: 0 Remote EndPoint Address: 61769829186283 WINSOCK: 'socket' Return Code: 0 WINSOCK: 'bind' Return Code: 0 WINSOCK: 'connect' Return Code: 0 WINSOCK: 'send' Return Code: 0 Bytes Sent: AT+COPS? WINSOCK: 'recv' Return Code: 0 Data Received: ERROR WINSOCK: 'shutdown' Return Code: 0 WINSOCK: 'closesocket' Return Code: 0 END: Application has completed! 

至less我希望我的问题能够帮助别人。

得到它的工作!

对于其他人,我的研究有很多,我希望这有助于:如果有,请投票!

你必须使用'HandsfreeServiceClass_UUID'UUID。 我也将流类型设置为发送方法中的'MSG_OOB'。

我的输出:

编辑如果你想发送短信,在GSM设备上将需要服务器套接字: Xamarin Android连接蓝牙设备或: Android蓝牙COM端口或SENA BTerm蓝牙终端
