Hello,
in my application I use the following part of my code:
#define IP_ADDR 0xc0a83E0A /*0xc0a83E0A- 192.168.62.10 */
void SetTCPClient(unsigned short usPort)
{
SlSockAddrIn_t sAddr;
int iSockID;
int iStatus;
unsigned char ucVal = 1;
long lRetVal = -1;
unsigned long g_ulDestinationIp = IP_ADDR;
/* Filling the TCP server socket address */
sAddr.sin_family = SL_AF_INET;
sAddr.sin_port = sl_Htons((unsigned short)usPort);
sAddr.sin_addr.s_addr = sl_Htonl((unsigned int)g_ulDestinationIp);
lRetVal = sl_NetCfgSet(SL_IPV4_STA_P2P_CL_DHCP_ENABLE,1,1,&ucVal);
if(lRetVal<0)
{
UART_PRINT("[ERROR] Can't set network parameters.\n\r");
}
/* Creating TCP Socket */
iSockID = sl_Socket(SL_AF_INET,SL_SOCK_STREAM, 0);
if(iSockID<0)
{
switch (iSockID)
{
case SL_ENSOCK:
UART_PRINT("[ERROR] Exceeded maximal number of socket.\n\r"); break;
case SL_ENOMEM:
UART_PRINT("[ERROR] Memory allocation error.\n\r"); break;
case SL_EACCES:
UART_PRINT("[ERROR] Permission denied.\n\r"); break;
case SL_EINVAL:
UART_PRINT("[ERROR] Error in socket configuration.\n\r"); break;
case SL_EPROTOTYPE:
UART_PRINT("[ERROR] Illegal type parameter.\n\r"); break;
case SL_EPROTONOSUPPORT:
UART_PRINT("[ERROR] Illegal protocol parameter.\n\r"); break;
case SL_EOPNOTSUPP:
UART_PRINT("[ERROR] Illegal combination of protocol and type parameters.\n\r"); break;
case SL_EAFNOSUPPORT:
UART_PRINT("[ERROR] illegal domain parameter.\n\r"); break;
default:
UART_PRINT("[ERROR] Resources allocation error.\n\r"); break;
}
}
/* Connecting to TCP server */
iStatus = sl_Connect(iSockID, ( SlSockAddr_t *)&sAddr, sizeof(SlSockAddrIn_t));
if(iStatus<0)
{
switch (iStatus)
{
case SL_EALREADY:
UART_PRINT("[ERROR] Non blocking connect in progress, try again.\n\r"); break;
case SL_POOL_IS_EMPTY:
UART_PRINT("[ERROR] There are no resources in the system, try later.\n\r"); break;
default:
UART_PRINT("[ERROR] TCP Connect.\n\r"); break;
}
sl_Close(iSockID);
}
}
when I call sl_Connect(...), the variable iStatus become -111, which mean Connection refused. What am I missing in my SetTCPClient function to establish connection between CC3200 and server with IP_ADDR IP address (server listen on port 3000,usPort = 3000). Thanks in advice.
Best regards,
Sergey Mihaylov.
