How to add DFU to ANCS example

[kibo]

Hi, I want to add DFU to ANCS example.

I use SAMSUNG GALAXY Note5, nRFToolbox, SDK 11, nRF52832, softdevice 2.0.1. Bootloader project I use is : nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\pca10040\dual_bank_ble_s132\arm5_no_packs, And ANCS projcet I use is : nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\ble_app_ancs_c\pca10040\s132\arm5_no_packs

When I try DFU, I select device and an application zip file then press upload button. After for a while, the device is automatically rebooted and the Toolbox application is repeating connecting -> starting bootloader -> connecting -> starting bootloader messages

I think there are some errors, so the device is rebooted. But I don't know where problems are and how to figure out where the errors are

Here are BLE Event IDs which are sent to ANCS device. 0x10, 0x14, 0x1A, 0x30, 0x50 then -> device is rebooted.

Thanks.

Here is command I use 'nrfutil.exe dfu genpkg exam.zip --application app.hex'

I don't know how to use nRFLogger. I think, When I try DFU with a device which has ANCS service, then the device is stopped.

In this example, 'nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\ble_app_ancs_c\pca10040\s132\arm5_no_packs' I use app_error.c file and checked the error location. An error is occurred sd_ble_gap_adv_stop() function in main.c

I commented out advertising_stop() in reset_prepare, then the device stuck at dfu_ble_svc_peer_data_set again........
