Part Number: CC3200-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH
Hello guys,
I used the CC3200 example "http_client_demo" to do as a "https client" . I downloaded secure_http_client_demo.7z. Then i added file main.c into http_client demo project. I have generated the certificate as per the document and flashed it . The time is set to the current time.But An error occurred"Connection to server failed.error(-102)".
The ConnectToHTTPServer function code：
static int ConnectToHTTPServer(HTTPCli_Handle httpClient)
{
long lRetVal = -1;
struct sockaddr_in addr;
#ifdef USE_PROXY
struct sockaddr_in paddr;
paddr.sin_family = AF_INET;
paddr.sin_port = htons(PROXY_PORT);
paddr.sin_addr.s_addr = sl_Htonl(PROXY_IP);
HTTPCli_setProxy((struct sockaddr *)&paddr);
#endif
#ifdef SECURE
SlDateTime_t dt;
/* Set current Date to validate certificate */
dt.sl_tm_day = 3;
dt.sl_tm_mon = 6;
dt.sl_tm_year = 2017;
dt.sl_tm_hour = 9;
dt.sl_tm_min = 51;
dt.sl_tm_sec = 0;
sl_DevSet(SL_DEVICE_GENERAL_CONFIGURATION, SL_DEVICE_GENERAL_CONFIGURATION_DATE_TIME, sizeof(SlDateTime_t), (unsigned char *)(&dt));
#endif
/* Resolve HOST NAME/IP */
lRetVal = sl_NetAppDnsGetHostByName((signed char *)HOST_NAME,
strlen((const char *)HOST_NAME),
&g_ulDestinationIP,SL_AF_INET);
if(lRetVal < 0)
{
ASSERT_ON_ERROR(GET_HOST_IP_FAILED);
}
#ifdef SECURE
#define SL_SSL_CA_CERT "/cert/129.der"
struct HTTPCli_SecureParams sparams;
/* Set secure TLS connection */
/* Security parameters */
sparams.method.secureMethod = SL_SO_SEC_METHOD_TLSV1_2;
sparams.mask.secureMask =SL_SEC_MASK_TLS_RSA_WITH_AES_256_CBC_SHA256 ; //SL_SEC_MASK_TLS_RSA_WITH_AES_256_CBC_SHA;
strncpy(sparams.cafile, SL_SSL_CA_CERT, sizeof(SL_SSL_CA_CERT));
sparams.privkey[0] = 0;
sparams.cert[0] = 0;
sparams.dhkey[0] = 0;
HTTPCli_setSecureParams(&sparams);
#endif
/* Set up the input parameters for HTTP Connection */
addr.sin_family = AF_INET;
addr.sin_port = htons(HOST_PORT);
addr.sin_addr.s_addr = sl_Htonl(g_ulDestinationIP);
/* Testing HTTPCli open call: handle, address params only */
HTTPCli_construct(httpClient);
#ifdef SECURE
lRetVal = HTTPCli_connect(httpClient, (struct sockaddr *)&addr, HTTPCli_TYPE_TLS, NULL);
#else
lRetVal = HTTPCli_connect(httpClient, (struct sockaddr *)&addr, 0, NULL);
#endif
if (lRetVal < 0)
{
UART_PRINT("Connection to server failed. error(%d)\n\r", lRetVal);
ASSERT_ON_ERROR(SERVER_CONNECTION_FAILED);
}
else
{
UART_PRINT("Connection to server created successfully\r\n");
}
return 0;
}
Host name and the port：
#define HOST_NAME "www.howsmyssl.com" //"<host name>"
#define HOST_PORT 44 3
I programed the certificate into the targert device by UniFlash.
the version information is CC3200SDK_1.3.0
When i run the project in IAR,it always returned "Connection to server failed. error(-102)" in this code " lRetVal = HTTPCli_connect(httpClient, (struct sockaddr *)&addr, HTTPCli_TYPE_TLS, NULL)"
who can help me?Grateful！

Guojing PAN.
