CC3200 OTA DropBox DataStores Deprecated

Hi Vic,

Thanks for notifying this.

While creating the new dropbox developer app you should use below option
Dropbox API->App Folder

We will update the documents accordingly.

Regards,
Ankur

Hi Ankur,

Thank you. I completed the task at www.dropbox.com, and wanted to add the code to the get_weather application. It states in the doc that there is an embedded .zip (Edits_for_OTA.zip )file that contains the code to add. When I click on the file, it is only an image, and not a zip file. Do you know where I can get this file?

Thanks,

Vic

HI Vic,

The zip file is not available but all the required code is listed in subsequent table. Please follow the instructions mentioned in table.

Regards,
Ankur

Hi Ankur,

That is not a great answer. The table is an image, and not text. There is no ability to cut and paste this code. I am going to need to type all of this in by hand which will take a long time, and be prone to error. Can you please see that this is fixed for the next person?

Thanks,

Vic

This should at least go here:
