Hi Satish,

Have you already gone through the setup steps found in this wiki:

Hi Gilbert,
Yes, I have followed the steps.
If I am using the NDK (TCP/IP wired), the compilation is passing.
The above errors is only when using SimpleLink library.

Regards,

Satish

After a bit of digging, it seems that WolfSSL is not supported on CC3100. Can I ask for more information about what you are trying to do with your application?

Hi Gilbert,

Thank you for the confirmation. The goal of the application is to interacting with Server (in cloud) using secured HTTP request response over wired TCP/IP or over Wi-Fi interface.

Satish

We have examples that you can look over if you use Code Composer Studio's Resource Explorer. If you go through TI-RTOS for TivaC and your Board, you can find some Network examples. You would be interested in one of the Ethernet Examples called "HTTPS Client GET" and one of the WiFi Examples called "HTTPS Client GET for CC3100". You can go through the README's they provide to get more information on how to adjust your setup.

One thing to note is that you cannot use both Ethernet and WiFi at the same time.

Hi Gilbert,

Sure, I have checked the HTTPS client get example. It is using sssl instead of using wolfssl.
Yes you are correct, I cannot use the Ethernet and wifi at the same time.

I am using NET_NDK in compiler option for usage of Ethernet (pre-compiler option) my compilation is through without any problem
But when I use NET_SL in compiler option for usage of Wi-Fi then I am getting "undefined first referenced ".

The problem is I am not able to figure out where is the problem, I have removed all the dependence on NDK in compiler and linker option.

Can you please revisit my first mail and review the root cause?
Thank you for your help.

Regards,

Satish

Here are two things you can try:

1. If you look at your cfg file, you can find the HTTP configuration. Tiva's Ethernet network stack uses NDK, but the CC3100 uses SimpleLink. It's possible you may have missed this.

/* ================ HTTP configuration ================ */
var Http = xdc.useModule('ti.net.http.Http');
Http.networkStack = Http.NDK; // For Ethernet
Http.enableTLS = true;

/* ================ HTTP configuration ================ */
var Http = xdc.useModule('ti.net.http.Http');
Http.networkStack = Http.SimpleLink; // For CC3100
Http.enableTLS = true;

2. If you are still having issues, would it be possible to zip up your project and post it here? This way we can build and fix it on our end.

A note: I spoke with the engineer who works closely with this, and he strongly recommends to upgrade to 2.16 if possible. There are quite a number of fixes for common problems that have been resolved that should have you some time down the road.
