我在C ++中并不强大！

有人能够告诉我哪里出错了，我正在尝试向蓝牙GSM设备发送和接收AT命令。这是三星Ace。

我一直在＆＃39; ERROR＆＃39;回。 Windows Software Development Kit (SDK) for Windows 10 - 但是所有AT命令都失败了＆＃39; ERROR＆＃39;

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: 'recv' Return Code: 0
        Data Received:
ERROR

WINSOCK: 'shutdown' Return Code: 0
WINSOCK: 'closesocket' Return Code: 0
END: Application has completed!

至少，我希望我的问题有助于其他人。

1 个答案:

答案 0 :(得分：0)

搞定了！

对于其他人，我的研究中有很多，我希望这有帮助：如果有，请投票！

我必须使用＆＃39; HandsfreeServiceClass_UUID＆＃39;你可以看到UUID。我还将Stream Type设置为＆＃39; MSG_OOB＆＃39;在发送方法中。

我的输出：

******************************************************

WINSOCK: 'shutdown' Return Code: 0
WINSOCK: 'closesocket' Return Code: 0
END: Application has completed!

修改 如果要发送短信，GSM设备上将需要一个服务器插座：Xamarin Android Connecting with bluetooth device 或：Android Bluetooth COM port或SENA BTerm Bluetooth Terminal
