Hi,

I asked the firmware specialist to provide this information about SDK etc. I/he will add it here.

Hi,

It was just my too quick assumption that you used the nRF Connect SDK, I see that was not specified. I have now tried to reproduce using the nRF5 SDK and rename the upgrade images to contain "confirmed", but still no success preproducing. Please provide detailed instructions on how to preproduce this issue (exactly how do you generate the upgrade images, exactly what are they named (as you write that is important) for which bootloader version, which nRF Connect for Mobile version do you use).

As far as I know from hardware people, the released version contains 2 bin files: with and without confirmed in the name. When I use confirmed FW on iPhone it closes the application, the same file on Android works ok. I think it's not about to rename the image to "confirmed.bin", both files have probably different content.

What I know from hardware people when they build/release the firmware it is "confirmation Firmware". They said it's a common format of files.

Hi,

I have not been able to reproduce this. I tested with the smp svr sample from NCS 1.6, and renamed the upgrade image to "app_update_confirmed.bin". With that, update using iOS 16.6 and nRF Connect for Mobile 2.4.12 the upgrade was successful as expected.

Can you explain in more detail exactly how to reproduce the issue you are seeing?
