Gmail example after google disabling SSL v3

Hi,

Good question. I am also interested. If you will contact R&D directly, please let me know.

Let me check with the R&D team and get back. It seems, we support, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 in R2 (next generation CC32xx), which is to be released later this year.

Thanks

I am informed about state of next gen but information about chipers is new for me. Actually I am not happy from that. But this is thing which we can't publicly discuss.

Hi,

at the moment, I found a workaround by setting the following in UARTCommandHandler() function:

        case UART_COMMAND_EMAIL_SEND:
        {

            // reset Orange LED state
            GPIO_IF_LedOff(MCU_SENDING_DATA_IND);
            // TODO: If no destination email given, default to hardcoded value
            SlNetAppEmailOpt_t eMailServerSetting;

            lRetVal = Network_IF_GetHostIP(GMAIL_HOST_NAME, &eMailServerSetting.Ip);
            if(lRetVal >= 0)
            {
                eMailServerSetting.Family = AF_INET;
                eMailServerSetting.Port = GMAIL_HOST_PORT;
                //eMailServerSetting.SecurityMethod = SL_SO_SEC_METHOD_SSLV3;
                //eMailServerSetting.SecurityCypher = SL_SEC_MASK_SSL_RSA_WITH_RC4_128_MD5;
                eMailServerSetting.SecurityMethod = SL_SO_SEC_METHOD_TLSV1_2;
                eMailServerSetting.SecurityCypher = SL_SEC_MASK_SECURE_DEFAULT;
                lRetVal = sl_NetAppEmailSet(SL_NET_APP_EMAIL_ID, \
                                        NETAPP_ADVANCED_OPT, \
                                        sizeof(SlNetAppEmailOpt_t), \
                                        (unsigned char*)&eMailServerSetting);
                ASSERT_ON_ERROR(lRetVal);
            }

Setting to TLS 1.2 and using SL_SEC_MASK_SECURE_DEFAULT, I managed to sent out the email.

hi Leo,

Did you make any add additional changes to make it work. I am using CCS 7.0 and CC3200_SDK_1.2 with your changes to email demo from above and still getting:

Cmd#05

Get Host IP succeeded.

Host: smtp.gmail.com IP: 64.233.185.109

Connection with Email Server Failed, Check Internet Connection and Retry

In addition to changes you made, I also modified:

long SetDefaultParameters(void)
{


    SlNetAppEmailOpt_t eMailServerSetting;
    eMailServerSetting.Family = AF_INET;
    eMailServerSetting.Port = GMAIL_HOST_PORT;
    eMailServerSetting.Ip = SL_IPV4_VAL(74,125,129,108);
//    eMailServerSetting.SecurityMethod = SL_SO_SEC_METHOD_SSLV3;
//    eMailServerSetting.SecurityCypher = SL_SEC_MASK_SSL_RSA_WITH_RC4_128_MD5;
    eMailServerSetting.SecurityMethod = SL_SO_SEC_METHOD_TLSV1_2;
    eMailServerSetting.SecurityCypher = SL_SEC_MASK_SECURE_DEFAULT;

Thanks
