    Hi,

    I have you tried to upload the same DFU package with our nRF connect / nRF toolbox to be sure it's not a problem with your custom app? Although it looks like the link is being terminated by the bootloader.

     Is everything supposed to be identical, or are you using a different mobile app, DFU firmware image, mobile, nRF device?

     mobile app(use your source code),  mobile, nRF device  is same .  DFU firmware image is different , bootloader and softdevice is same.
