OTA update fails in CC3200

Hi All,

 

We are using the Dropbox API to do an OTA upgrade. We have a webclient application running on the TI microcontroller CC3200. We are using the Drop Box API from 2017 onwards, and it is working fine. When we tested the OTA functionality yesterday, it was unable to receive the CDN file URL.

It is able to receive the file information from Dropbox but is unable to get the temporary link from Dropbox.

Do you know what is causing this issue? Is there any recent API upgrade that has failed to respond?

Please help us to fix this issue ASAP.

    This output doesn't show the actual request/response for the API call. Are you able to retrieve the actual request and response showing the issue?

     

    I'm not aware of a bug on the Dropbox servers that should be causing this. This sounds like this earlier report we received, but we weren't able to identify or reproduce the actual issue there.

      Hi Greg,

       

      Thank you for reply.  We have many WIFI module chipsets like CC3200, CC3220, CC3235. All of them failed to receive the data from Dropbox. Texas instruments claims that the chipset could not able to send and receive data using their low level HTTP Client library.  Did you modified anything related API (TCP/IP layer changes) for last 2 to 3 months? It was worked for past 5 several years. It is now impacting our business and our clients. Could you please help us to resolve the issue.

        While there may have been updates to the Dropbox servers in this time, I'm not aware of anything that should be causing the servers to incorrectly fail on API calls like this.

         

        If there seems to be an issue with the Dropbox API, please share the actual raw HTTP request and response (showing both the headers and bodies for both, but redact the access token) so we can reproduce the issue and look into it. Thanks!
