Is someone able to tell me where I am going wrong, I am trying to send and receive AT Commands to the Bluetooth GSM Device. It’s a Samsung Ace.

I keep getting 'ERROR' returned. The command returns "OK" ..., and "ERROR" otherwise - However all AT Commands Fail with 'ERROR'

I have tried several UUID GUID's.

My Output is like so:

******************************************************
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!

At the very least, I hope my questions help others.

解决方案

Got it working!

For others out there, and there are many from my research, I hope this helps: If it has, please vote up!

}

I had to use the 'HandsfreeServiceClass_UUID' UUID as you can see. I also set the Stream Type to 'MSG_OOB' in the send Method.

My Output:

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

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

EDITIf you want to send SMS Messages, a Server Socket will be needed on the GSM Device: Xamarin Android Connecting with bluetooth deviceor: Android Bluetooth COM port or SENA BTerm Bluetooth Terminal
