Hi,

Are you testing on a nordic dev kit or a custom board?

Have you checked that you are not using NRF_BL_DFU_ENTER_METHOD_PINRESET to enter DFU mode on pin reset automatically?

You can also check inside dfu_enter_check() function to see in which conditions the bootloader will go into DFU mode or not.

Best regards,

Marjeris
