How to use http_client demo example and HTTP client connect fail error -102

Tuan Khoa Nguyen said:

I don't know where to add the code snippet in the instruction and where to place/call HTTPCli_connect function in file main.c.

I think TI should give more details for a newbie like me.

1. For non-secure http connection you need to modify value of  HOST_NAME, HOST_PORT, SSID_NAME, SEC_TYPE and PASSKEY macros as mentioned on tutorial.

2. In case of secure http connection in existing http client example you need to add code snippet before the HTTPCli_connect() and change

   "HTTPCli_connect(&cli, (struct sockaddr *)&addr, 0, NULL);"  to   "HTTPCli_connect(&cli, (struct sockaddr *)&addr, HTTPCli_TYPE_TLS, NULL);"

Fortunately, i find this post and downloaded secure_http_client_demo.7z. Then i added file main.c into http_client demo project.
 I don't know how to use this file "howmyssl.der.cer " so i do nothing with it.


You need to flash certificate "howmyssl.der.cer" at /cert/1.crt using uniflash.

Hi,

Thank you for your replying

I follow this tutorial in section 8 to add the certificate. I change "howmyssl.der.cer"  to  "1.cer"  and config like the attachment picture 

But when I run code on the board I still getting following error

 

Hi,

Does anyone know how to deal with this ? Can you help me

Hi Khoa,


Please run in debug mode and jump into HTTPCli_connect() and share what error code connect() API return.

Aashish

Hi,

I run in debug mode and jump  into HTTPCli_connect() like you said.

 

and I don't see any error in ccs debug

and i'm still confuse about the Http_client_demo example.

+ I don't know how to get the certification of the website ( ex: google speech api , Wit.ai ) 

+ if i don't have the certificate, what should i do with this line strncpy(sparams.cafile, SL_SSL_CA_CERT, sizeof(SL_SSL_CA_CERT));

Jump in to HTTPCli_Connect() and share return value (ret) of connect(skt, sa, slen); API

Contact your server support team(ex: google speech api , Wit.ai) to get more information about how to get certificates for secure connecion to their server

If your server support non-secure connection then try to run http client example in non-secure mode (undefine SECURE macro in your example code)

Hi

Does the current time is important ?

    SlDateTime_t dt;

    /* Set current Date to validate certificate */
    dt.sl_tm_day = 20;
    dt.sl_tm_mon = 3;
    dt.sl_tm_year = 2016;
    dt.sl_tm_hour = 15;
    dt.sl_tm_min = 57;
    dt.sl_tm_sec = 00;

I cannot set the time correctly when i flash the code.

And how to add a certificate in project CCS and uniflasf correcly

No need of set exact time. Approx time is ok. If you still want to use exact time than get current time using Network time protocol at set it.

In uniflash click on button "Add File" and rename it to the name that you are going to use in code for example "/cert/testcacert.der"

Hi,

Thank you for your reply

So if i use CCS to debug code, how to add certificate in CCS.

Or I just flash the project contains the certificate. After that i debug the project by CCS. The certificate still in CC3200 right ?

Khoa

Hi Khoa,


You just need to flash certificate after that you can debug from CCS.

Hi,

I debuged and jumped into HTTPCli_connect 

I still using the code secure above

Hi Khoa,


What is the value of lRetVal at this point.


Regards,
Aashish

Hi Aashish,

The value is -102.

If i want to use HTTPS  POST to https://www.howsmyssl.com  or https://www.google.com/speech-api/v2/recognize 

Does the example HTTP_Client demo is enought or i have to combine more examples ( like SSL_demo) ?

 

Best regards,

Khoa

Hi Khoa,

Step into HTTPCli_Connect() API and share return value (ret) of connect(skt, sa, slen); API

Hi Aashish,

I have another problem.

Now the error is  "Error [-2012] at line [1192] in function [ConnectToHTTPServer] "

I found the answer in this link but i didn't know how to change the code.

Would you mind helping me.

Hi Khoa,


What is the HOST NAME?


Regards,
Aashish

Hi Aashish,

#define HOST_NAME  "https://www.google.com"
#define HOST_PORT 443

#define POST_REQUEST_URI "/speech-api/v2/recognize"

#define POST_DATA  EncodedBase64_data

HTTPCli_Field fields[4] = {
{"Content-Type","audio/l16; rate=16000;"},
{"output","\"json\", \"lang\": \"vi-VN\", \"key\": \"My_key\""},
{NULL, NULL}
};

I have used temboo to connect with google api and it works but it took  1 minute to receive the return value. 

So i think cc3200 connect directly to google api will work faster and i am not used to using energia.

regards,

Khoa

Hi,


Change HOST_NAME from ""https://www.google.com" to ""www.google.com" as you don't need to pass http/https for DNS resolution.

Hi Aashish,

Thank you for your help.

It appears the error like this

Do you know about this ?

Hi Khoa,


Which SDK are using if you are using SDK 1.2.0(host driver 1.0.1.6) than its mean "remote side down connection from secure to unsecured" and if you are using SDK1.1.0(host driver 1.0.0.10) than its mean "connection less mode, rx packet fragmentation > 16K, packet is being released". Please refer SL_SOCKET_ASYNC_EVENT in socket.h


Regards,
Aashish

Hi Aashish,

I am using SDK1.1.0(host driver 1.0.0.10).

If i reset cc3200, that line doesn't appear again but google api still not received anything .

When i use energia to send temboo the same data, it works properly .

Should i split a data into smaller then sent HTTPCli_sendField  and  HTTPCli_sendRequestBody respectively, right ?

Update: Even i sent the small data (12kB) . Google api still not received anything

Khoa

Hi,Khoa.
