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.

Hi, so you are telling you are testing with buttonless code ? I assume you have no trouble doing DFU to update the image. Only having trouble with switching from application to bootloader ? Please list exactly the step you used for testing, start with step 1 flashing the softdevice.

Have you tried to test with the ble_app_hrs_with_dfu ? The buttonless example in our SDK ?

You said "An error is occurred sd_ble_gap_adv_stop() " what error ?

then the device stuck at dfu_ble_svc_peer_data_set(), how do you know that ? If you simply step through the code, it won't work because it's an svc call , and the code is in the bootloader code, Keil won't be able to follow.
