Hello TI Team,

I am using SDK V1.5.0. I have evaluated file download example to download the file from unsecured http sever(port 80).

Our company servers are HTTPS server and uses SSL certificates and uses CA file(.der format) for connection.

Please, support us for connection to https server (port 443) using CA file to download the file.

Thanks and Regards,

Rohit

Hi Rohit,

Are you able to perform an HTTP unsecured transfer to test out your HTTP GET settings, to make sure that your HTTP request is correctly formatted? This will save time in later debug in case we can't get the HTTPS working right away.

If the HTTP request is fine, then the next steps is to simply add in the code to make it a secured socket. The needed code can be found in this E2E post:

In addition to the code, you will need to provide the root CA cert that your HTTPS server uses to validate its cert chain. The most reliable way to check which root CA is being used is to connect to it using your browser on your PC and then use your browser's tools to check the cert chain.

Once you've identified the cert you can load it using Uniflash. Instructions can be found here: https://www.ti.com/lit/ug/swru558/swru558.pdf

Let me know if you need more clarification, or have further questions on the steps needed to enable HTTPS on the CC3200.

Michael
