Hi there!

I'm creating windows application in C++, which connect's PC with mobile via bluetooth and winsock. Allow's you to call and send messages from mobile via computer.

I'm using AT command's to tell mobile what i want to do. Pair with mobile device and force a call with At command

ATD+420******;

works perfect, but all commands for handling SMS like

AT+CMGL, AT+CMGF, AT+CMGS etc.

return's ERROR.

Here is code which connects PC with mobile via bluetooth and socket:

SOCKADDR_BTH RemoteEndPoint;
	RemoteEndPoint.port = 0;
	RemoteEndPoint.addressFamily = AF_BTH;
	RemoteEndPoint.btAddr = m_foundDevices[m_deviceIndex].Address.ullLong;
	RemoteEndPoint.serviceClassId = HandsfreeServiceClass_UUID;
	int BTHAddrLength = sizeof(RemoteEndPoint);

	// Create the socket.
	if ((m_localSocket = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM)) == INVALID_SOCKET)
	{
		// handle error.
	}

	// Connect the socket.
	if ((iResult = connect(m_localSocket, (SOCKADDR *)&RemoteEndPoint, sizeof(RemoteEndPoint))) == INVALID_SOCKET)
	{
		// handle error.
	}

Notice line

RemoteEndPoint.serviceClassId = HandsfreeServiceClass_UUID

I think the problem is here, becouse u cant send sms from Handsfree, but when i use another UUID, it doesnt even pair with mobile.

=== Here is just for info, how am i sending and receiving data from mobile ===

char recvbuf[DEFAULT_BUFLEN] = "";
const char *sendbuf = "AT+CMGL\r";
int len = (int)strlen(sendbuf);
if ((iResult = send(m_localSocket, sendbuf, len, MSG_OOB)) == SOCKET_ERROR)
	{
		// handle error. return ~0
	}

	if ((iResult = recv(m_localSocket, recvbuf, recvbuflen, 0)) == SOCKET_ERROR)
	{
		// handle error. return ~0
	}
// Here recvbuf == "\r\nERROR\r\n"

Thank you for any advices! If you have any question's about problem, i'll kindly explain.
Regards,
Filip.

What I have tried:

Use another phones, with other OS. <- Didn't work.
Use another UUID's <- Didn't work.

Googling a lot of hour's, didn't find any solution.
