The Zip file for updating in the DFU APP does not open.

[David_Kim]

HI

I have been using the DFU APP to create a zip file and update it.

However, this time, when I created a zip file to update and tried to use the zip file in the DFU app, it was disabled and could not be selected.

The photo below is a screen capture for opening a zip file to update in the DFU APP.

The upper file in the photo below is the zip file I created this time (not selected), and the one below is the zip file I created previously and used well.

The icon on the left is also different.

In a hurry, I tried it in the nRF Connect app and the update was successful with the zip file that was not selected above.

However, the icon is different.

Hello,

Sorry, but I didn't fully understand the issue. Could you please clarify which SDK version you are using?

Are you saying that the DFU application is unable to select the ZIP file you generated, while the nRF Connect app can handle it without any issues? Are you using nrfutil in this process?

Could you let me know which Nordic chip or Development Kit (DK) you're working with?

Kind regards,
Abhijith

That's right. As you said, the zip file is not selected in DFU, but it is selected in nRF Connect APP.

And the update is actually successful.

However, the zip file in nRF Connect APP has a different icon than the zip file recognized in DFU APP.

Check the captured image in the main text.

I am using it as my own PCB using nRF52832.

I have previously created many zip files for the mass-produced PCB and updated them well with the DFU APP, but this phenomenon suddenly occurs.
