Zip file failed to upload for ble_secure project

Hello, I am working on ota ble_secure project. I have created a zip file which is the last step and copied this file to my smart phone so that I can upload it using nrf toolbox. The upload fails. I am not sure which files to include to create a zip package. I am attaching my zip package as well as the files that I used to merge.app_dfu_package.zip. The hex file is nrf52832_xxaa_s132.hex.

The log file of error is log.txt

Sdk which I have is www.nordicsemi.com/.../nRF5-SDK

I am using this project in sdk sdknordic\examples\dfu\bootloader_secure\pca10040

Left side is new sdk and right side is old sdk. bootloader.PNG

Log file New Text Document.txt

New log file errorlog.txt

  • Could you point me where you found "nrf51latest13alpha SDK" ? There is nothing like that from Nordic.

    If you only update the application, you only need the application .hex file. This find you can find in the _build folder after you compiled your project.

    After that you use "nrfutil.exe dfu genpkg" to generate the .zip file. For example if the hex is yourapplication.hex the script can be:

    nrfutil.exe dfu genpkg app.zip --application yourapplication.hex --application-version 0xffff --dev-revision 0xffff --dev-type 0xffff --sd-req 0xfffe
