Hi,
I trying to build a TCP Server on CC3200MOD Launchpad with multithreading. But there is always accept connection error. The sl_Accept(); returns a value -100 which is not defined as any macro. Can you tell me what type of error is this? and how can i resolve it?
Hi,
I have got the log file of the project. 
Also, some code snippet is here.
void ServerRoutine(void *NewSock)
{
char buff[1024];
int iStatus;
int NewSoc=*((int *)NewSock);
Report("I am in Routine Func");
again: iStatus = sl_Recv(NewSoc, buff, 1024, 0);
if(iStatus==SL_EAGAIN)
goto again;
else if( iStatus <= 0 )
{
// error
sl_Close(NewSoc);
Report("Error on recpetion:%d\n\r",iStatus);
//ASSERT_ON_ERROR(RECV_ERROR);
}
else
{ buff[iStatus]='\0';
Report("Data recieved:%s\n\r",buff);
Report("Recieved packet successfully\n\r");
// close the connected socket after receiving from connected TCP client
iStatus = sl_Close(NewSoc);
if(iStatus!=0)
Report("Error in closing connection %d\n\r",iStatus);
//ASSERT_ON_ERROR(iStatus);
NewSoc=-1;
}
osi_TaskDelete(NULL);
}

Hi,
I got the log file please let me know the problem. The code snippet is given above and log file is here:
Hi Michael,
I uploaded the code provided by you. The device connects to SSID="simplelinktest" successfully and I was able to connect my first tcp client with it. But the second client fails to connect (it waits till the first on exits). I have got the terminal window, have a look.
Hi Michael,
I was trying to understand your code and that's why I imported the project into CCS v6 (Earlier I was using IAR). But when build the project I see some errors like:
After looking the errors I checked include paths which were like this :
Then I changed all the path to :
$C:/TI/CC3200SDK_1.3.0/cc3200-sdk/simplelink/ (like this).
But still, I'm getting the same errors.
Can you help me?
