SYS_MODULE_OBJ SYS_NET_Open (SYS_NET_Config *cfg,
SYS_NET_CALLBACK Net_cb,
void *cookie)

Returns: If successful, returns a valid handle to an object. Otherwise, it returns SYS_MODULE_OBJ_INVALID.

SYS_NET_Config 	g_NetServCfg;
SYS_MODULE_OBJ 		g_NetServHandle;

memset(&g_NetServCfg, 0, sizeof(g_NetServCfg));
g_NetServCfg.mode = SYS_NET_MODE_CLIENT;
strcpy(g_NetServCfg.host_name, APP_HOST_NAME);
g_NetServCfg.port = APP_HOST_PORT;
g_NetServCfg.enable_tls = 0;
g_NetServCfg.ip_prot = SYS_NET_IP_PROT_UDP;
g_NetServHandle = SYS_NET_Open(&g_NetServCfg, NetServCallback, 0);
if (g_NetServHandle == SYS_MODULE_OBJ_INVALID)
{
    // Handle error
}

This routine should be called everytime a user wants to open a new NET socket. Also, in case the user is opening a Client Socket, and the under lying network interface is Wifi in AP Mode, it is recommended that the call be made only after the STA running the server connects to the AP on the Wifi interface.
