Simple RSocket Application in emulator

[swivel_sweeper@yahoo.com]

Hi All,

I'm trying to run a simple (connectionless) socket-application on the emulator.
This is the meat of the code (I use an active object and iSocketServ is connected):

	// define, open, bind a local socket desc
	RSocket socket; 
	User::LeaveIfError(socket.Open(iSocketServ, KAfInet, KSockDatagram, KProtocolInetUdp));

	// set the dest address: udp/ip addr
	TSockAddr sourceAddress(TInetAddr(INET_ADDR(127,0,0,1), 1074));

	if ( socket.Bind(sourceAddress) != KErrNone )
		{
		socket.Close();
		//User::LeaveIfError(err);
		}

	TInt len = 500;
	TSockXfrLength aLen = len;

	// set the constant data buffer
	TPtrC8 aDesc ( (TUint8 *) "TEST data for UDP of size 350");

	// set the dest address: udp/ip addr
	TSockAddr destinationAddress(TInetAddr(INET_ADDR(192,168,0,59), 1075));
	socket.SendTo(aDesc, destinationAddress, KSIConnectionLess|KSIMessageBased, iStatus, aLen);
	SetActive();

	socket.Close();

When I execute it on the emulator I get a -5 (no such operation) as a response (in the RunL-method)
I Use:
- Symbian OS 7.0 (Series 60 SDK 2.0)
- SIP-plugin
- Ethernet Plugin
- VS .Net 2003
- Ethereal for monitoring.

I've tried:

- 'Setting up Ethernet connection' with the manual from symbian. No result in ethereal.

- Modify and re-import the cedout.cfg:

	[ConnectionPreferences]
		ADD_SECTION
			Ranking=1
			Direction=OUTGOING
			DialogPref=DONOTPROMPT
			BearerSet=LAN
			IAP=1
			FIELD_COUNT=5
		END_ADD

Still no result.

- using prnesock.lib instead of esock.lib, I get an 'unhandled exception' when te sendTo-method is called.

Does anyone have any idea?

Hello,

I see something is wrong in your code if all those code belongs to the same method. You are closing the socket (socket.close()) after making asynchronous call socket.SendTo(). You should close the socket in RunL() when the socket is no longer needed.

Active object usage is something not available in at least PC side C++ and Java languages. I had a hard time understanding that at first and the RunL() function.
