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

Hello,

Sorry for getting back to you a bit late. It's the summer vacation period here, and the workload is relatively high, which is causing more delays in responses than usual.

I was reviewing the command for generating the DFU package, and to confirm whether it's correct, I’ll need some details about the SDK version you’re using. I checked the release notes but couldn’t find the firmware ID (0x0103) you mentioned in the nrfutil command.

Could you please confirm if the command you used is correct? Also, would it be possible for you to share the generated ZIP file?

Kind regards,
Abhijith

HI, Menon

[quote userid="115767" url="~/f/nordic-q-a/121779/the-zip-file-for-updating-in-the-dfu-app-does-not-open/537665"]We need to check if there is any problem with the device firmware application. Could you please let me know how I can reproduce this issue? How was the mentioned ZIP file generated, and what version of the DFU app are you using? Does this issue occur on different phones and platforms (Android/iOS)?[/quote]

1. The ZIP file was created with the command below.

nRF52832 / S132

nrfutil pkg generate --hw-version 52 --sd-req 0x0103 --application-version 1 --application test_user_hex --key-file priv.pem dfu_package_test_user.zip

2. The Android version of the smartphone that had the above problem is 9.0.

I didn't review this smartphone before because it worked well, but as you said, it's a good choice when you try it with another smartphone.

It seems that it may not work properly depending on the Android version.

Hi,

Abhijith isn't available today (long weekend for many in Norway) and is most likely back on Monday.
We will get back to you early next week. Thanks for your patience in advance.

HI, Menon

[quote userid="115767" url="~/f/nordic-q-a/121779/the-zip-file-for-updating-in-the-dfu-app-does-not-open/537055"]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?[/quote]

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.

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?
