CC3220SF-LAUNCHXL: CA File update via Inbuilt web server

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH

Hi,

I want to Add / change / update the existing CA certificate files stored within the flash. I understood that the only user interface is Uniflash which I can not allow my clients to use. I am using HTTP web server of CC3220 and want to use the same interface for updating my CA files within the flash.

Do you have any example, where files can be uploaded to simplelink device using any browser with its HTTP server module..

Regards

    Hello,

    You are reffering to Over-The-Air process for updating bundle of files.

    Yuo can refer to local_ota, out_of_box or cloud_ota for more reference.

    Hi,

    Thanks for reply!

    Yes! I am using OTA for my firmware upgrade, but since as I understand, the OTA bundle needs to be created from Uniflash tool and then whole bundle including other system files are getting updated.

    Here I just wanted to make provision for admin users to update single certificate file via web server interface provided by Simplelink.
    please let me know if you have any solution to do the same.

    You can use the same reference.

    Although the reference is using the OTA tar file but it shows the mechanism of sending a file (HTTP_PUT) over HTTP to the internal server, and the server sends it to the host for further processing.

    Then, you can use the file system APIs instead of the ota_archive to write it to the serial flash.
