Hi:
I use sdk nRF5_SDK_17.1.0_ddde560. bootloader use examples\dfu\secure_bootloader\pca10056_uart_debug.
It cann't enter the application.
But If I use examples\dfu\secure_bootloader\pca10056_s140_ble_debug.
It can enter the application.
Except for the bootloader, their other applications, dfu_ppublic_key, and softdevice are the same.
