https://devzone.nordicsemi.com/f/nordic-q-a/21928/adding-custom-json-entries-to-manifest-json-and-custom-zip-fileHey devs! We&#39;d like to add additional fields in the manifest.json when generating (or after generating) the zip file for DFU. We need these fields to make additional compatibility checks in our Android app before starting the whole DFU cycle.

I guess the problem you have is that when your are zipping a folder it doesn&#39;t zip only the files (so that they are on the main level in zip) but a folder, do then this folder is in main level and files inside. The dfu libs for ios and Android look for manifest on the root level in the zip.</p><div style="clear:both;"></div>
