OTA for CC3200 Corrupted Download file.

OTA for CC3200 Corrupted Download file.

We are using dropbox to host update files for a hardware device that uses a cc3200. Last week our devices were no longer able to retrieve a file update file from dropbox. When we test the download it is returning an invalid file of the correct size. 

 

Were any changes made in the past few weeks that would cause this to happen?

What were these changes? 

Have any other customers reported this issue? 

 

We are confident that this is a dropbox issue, we ran a local test redirecting traffic to a local server that returns the same file and everything works. But if we download the same file from dropbox it fails.

You can see that in the file dropbox returns it is appending a few bytes at the front. 

 

Thanks for checking.

Update: the team has been able to complete some further updates to our infrastructure to be able to support the previous non-chunked behavior going forward indefinitely. That means that we plan to continue returning Content-Length (and not 'Transfer-Encoding: chunked') in the future and will not be reverting this on 3/14. (Regardless, for HTTP compatibility in general, we still recommend you make sure your HTTP clients support both types.) Hope this helps!
