single slot with firmware loader

[brave_niuniu]

Ncs v3.2.1
<SDK>\nrf\samples\dfu\single_slot

I want to try using this sample for SMP over ble dfu, so I tried several times in the nRF Connect and Device Manager in the mobile app, but after adding dfu_application.zip, it always prompts "Invalid image file".
I am very confused and hope to get an answer, thank.

Hello, 

I did not manage to reproduce this error with iOS. Are you using Android? Please also try to see if you get the same error with my DFU package below.

2475.dfu_application.zip

Best regards,

Hi vidar，

It is indeed an issue with the app. I don't know why this problem occurs on Android if the nRF Connect version is lower than 4.29.1, but it doesn't matter, as long as it works. Thank you for your answer.
