We want to know how to send JSON post using secured HTTP (HTTPS) by using CC3200 launch expo

Hi Surya,


Please refer http_client example to post data in JSON format. There is no difference in the way post request formatted for http or https except for some extra header needed depend upon the server. For https only connection need to be secure. Please refer ssl example from SDK for establishing secure connection.

Hi Surya,

I have open source code and instructions that shows how to do this - github.com/.../CC3200_Azure

Note, this does not use the HTTP Client Libraries, but instead I build the HTTP POST packet on top of the Sockets packet.

Glenn.

Hi Glenn,

Thanks for your reply.

we compiled source code(github.com/.../CC3200_Azure) by using IAR work bench, but we are getting the following compilation Issues.

Error[Pe040]: expected an identifier D:\SURYA_WIFI\CC3200SDK_1.1.0\cc3200-sdk\oslib\osi.h 59
Error[Pe020]: identifier "PERIODIC_TEST_CYCLES" is undefined D:\SURYA_WIFI\CC3200SDK_1.1.0\cc3200-sdk\example\ssl1_test\main.c 541

Could you please help in resolving these issues?

Thanks in Advance.

How to implement HTTP SSL connection with server without out using certificate(SL_SSL_CA_CERT_FILE_NAME).

Regards,

I am not aware of any method that allows you to create a secure socket with out installing a certificate

Hi,

By using cc3200 launch Http client code we implemented HTTP secure connection(SSL)and I tried with the following hosts .

Host:Google
port:443
Downloaded google certificate in flash.

O/P:
Host Driver Version: 1.0.0.10<LF><CR>
Build Version 2.2.0.1.31.1.2.0.2.1.0.3.23<LF><CR>

Now I am trying to connect httpbin.org host ,but I am unable to connect .

Please tell me any testing hosts for testing HTTP secure connections

Could you please help in resolving these issues?

Thanks in Advance.

Hi,

I am working on CC3200 and trying to connect to webserver securely (SSL). I have followed the guide lines at

processors.wiki.ti.com/.../CC32xx_SSL_Demo_Application

and was able to connect to google server successfully.

But now my requirement is not to preload the CA certificate on to SFLASH but still I need to connect to the web server.

Can some one let me know some example or procedure how to connect to webserver without preloading the CA certificate
on to flash since in run time I should be able to connect to the server dynamically.

Thanks in advance

Hi,

I need to connect to apps.lifetechnologies.com
I have to send user name and password as part of POST in json format and be able to login to the above mentioned site
Any suggestions on this?

Thanks in advance

Hi Glen,

In source code I have some doubts

In Main.c

#define AUTHHEADER "Authorization: SharedAccessSignature sr=swiftsoftware-ns.servicebus.windows.net&sig=6sIkgCiaNbK9R0XEpsKJcQ2Clv8MUMVdQfEVQP09WkM%3d&se=1733661915&skn=EventHubPublisher\r\n"

what is the AUTHHEADER ? How to generate this code for our application.Tell me the procedure how to generate this signature.

Could you please help in resolving these issues?

Thanks in advance

Regards,
Surya

This is all detailed with my IoT Proof of Concept - github.com/.../CC3200-LaunchPad-Setup

Look at - Generate Shared Access Token..

Are you sending the packets to Microsoft Azure?

Glenn

Hi Glenn,

No,By using your application source code we are trying to connect //test.apps.lifetechnologies.com/egw/endurancegw/api/v1/devices/register

we did the following modifications.

Changed Host address ://test.apps.lifetechnologies.com/egw/endurancegw/api/v1/devices/register
Flashed certificate in CC3200 launch Expo,

but still we are unable to connect the host.

Could you please help in resolving these issues?

Thanks in advance

The Token you see is for Azure's method of Claims Based Authentication....I have no idea if you require this on your site, most likely not. Hence you can forget about that Header.

Regarding your issues, what error are you getting returned, any other information to help you debug the issue?

You will need to use the root CA that is required for your site....it may not be the same one i use for Azure. 

I recommend going through these steps -  

Glenn,

Hi Glenn,

I was uploaded root CA certificate of my site as per the above mentioned steps.But still we are unable to connect.

Regards,
Surya

What line of code have determined fails? What error number is returned? What else have you done to debug this issue?

Please share the site URL and upload the root ca you are using to a post as a zip file.

Glenn

Hi Glenn,

Thanks for your reply,

Requirement:
Host Server: test.apps.lifetechnologies.com
Port=443
Connection type=SSL

These are the modifications implemented in code.

#define HOST_NAME "test.apps.lifetechnologies.com"
#define HOST_PORT 443
#define POSTHEADER "POST test.apps.lifetechnologies.com/.../register HTTP/1.1\r\n"

#define SL_SSL_CA_CERT_FILE_NAME "/cert/129.der"(created file as per the SSL example code and flashed certificate)

ucMethod = SL_SO_SEC_METHOD_TLSV1;
uiCipher = SL_SEC_MASK_TLS_DHE_RSA_WITH_AES_256_CBC_SHA;


we are getting error number (-340 ) while connecting to the peer device.

/* connect to the peer device - Google server */
lRetVal = sl_Connect(iSockID, ( SlSockAddr_t *)&Addr, iAddrSize);

Error Number=-340(SL_ESEC_HANDSHAKE_FAILURE)

Console output:

Could you please help in resolving these issues?

Hi Surya,


Is it CA uses SHA384 as what we can see in browser. If yes, sorry CC3200 doesn't support SHA384.
