buttonless dfu examples in sdk14.2 is not working for me

[Cabbage]

Hi there,

The dfu secure bootloader example is working fine with my nrf52832 sdk14.2 s132. but the experimental buttonless dfu in the example is not working for me. I was able to transfer the application through my iPhone nrf_connect to my board, the LED1 stop blink, LED1 and LED3 hold on shine，and the nrf_connect in my iphone show start, always update: 0%, util the board timeout;

the example i have tested in SDK_dir/examples/dfu/sevure_dfu_test_images/ble/nrf552832/ softdevice_bootloader_secure_ble_debug_without_bonds_s132.hex; ble_app_buttonless_dfu_without_bonds_s132_with_setting_page.hex;

the firmware： ble_app_buttonless_dfu_without_bonds_s132.zip;

Thank you in advance!

Hi Cabbage,

Could you list exactly all your steps for both when "bootloader example is working fine", "experimental buttonless dfu in the example is not working " , I want to see how you flash the softdevice, bootloader application, and the order.
