Over the air download via API fails today, worked yesterday.

Hi,

  I have an embedded device that downlopads firmware updates over the air via the DropBox API.  Downloads worked fine yesterday, and fail today.  The code has not changed since then, and I even went back to a revision built a few months ago, and it fails in exactly the same way.  I am using a Texas Instruments CC3200 processor.  I use the TI library for the OTA process.  It can list the files in the repository, but when I try to access them via the link provided the device just hangs.  It subsequently reboots.  Here is some diagnostic output from the process.

sl_extLib_OtaRun: call OtaClient_ConnectServer OTA server=api.dropbox.com
OtaClient_ConnectServer: http_connect_server api.dropbox.com
[00:00:11.0967] OTA run (0)

After the last line the device hangs until the system watchdog reboots it, then the process repeats.  Any idea what I might be running into?

Thanks,

Vic Berry

@BAB1 The length of the returned link depends on a few things, including the file path, based on how it's implemented on the Dropbox servers. It's possible the length did increase due to some backend change recently.

I'm checking with engineering to see what may have changed here, and to see if we can potentially revert it, but I can't make any promises with respect to that right now.

Unfortunately, I don't have any other workarounds to offer.

Hi Greg,

  I would like to add my voice to the chorus of people asking for this to be escalated.  I have thousands of devices that are affected by this also, and it would cost us a prohibitive amount of money to replace them in the field.  Additionally the customer support issues would be a nightmare.

Thanks,

Vic

@Greg seems like a very big issue to me.

I can't imagine honestly 300K people complaining to dropbox. Can't you? 

Do you have any updates?
