I am trying to integrate GitHub - NordicSemiconductor/IOS-DFU-Library: OTA DFU Library for Mac and iOS, compatible with nRF5x SoCs library in one of the SwiftUI mobile application. The integration was easy due to really well documentation instructions on the library page.
I went ahead and tried to load my ZIP file, but it gave me "CRC does not match!" error in the logs, and then DFU process just stuck at aero progress.
Then I tried to load DFU using your app, which is currently on AppStore - nRF Connect for Mobile on the App Store (apple.com), but I got the same log
I am trying to integrate GitHub - NordicSemiconductor/IOS-DFU-Library: OTA DFU Library for Mac and iOS, compatible with nRF5x SoCs (v4.11.1) pod library in one of the SwiftUI mobile application project. The integration was seamless due to really well documentation instructions on the library page.
I went ahead and tried to load my ZIP file, but it gave me "CRC does not match!" error in the logs, and then DFU process just stuck at zero progress.
Then I tried to load DFU using your app, which is currently on AppStore - nRF Connect for Mobile on the App Store (apple.com), but I got the same error in log (attached TXT version log from nRF iOS app)

I also tried nRF Connect Android app from Play Store, with same BLE device and same ZIP file, it worked!
I am not sure why iOS DFU library or nRF Connect iOS app giving CRC error.
Any help would be appreciated.
I have tested this on iPod Touch (iOS 14.8)
