how to create "ble_app_buttonless_dfu_without_bonds_s132.zip" dfu file

[Rajneesh]

Hello Everyone,

I am working on nRF5 14.1.0 SDK, My question is how to generate "ble_app_buttonless_dfu_without_bonds_s132.zip" dfu file.

Can any one tell me the exact command so that I can generate the DFU file. I am using SEGGER embedded studio for project file compilation.

Softdevice id: 0xcafe.

I have generated DFU file by following below commands but this file is not working, when I am uploading the file through nRFTool box it's says "INVALID OBJECT".

"nrfutil.exe dfu genpkg --application ble_app_buttonless_dfu.hex --application-version 0xffff --dev-type 0xffff --dev-revision 0xffff --sd-req 0xca,0xfe dfu_test_file.zip"

But if I use "ble_app_buttonless_dfu_without_bonds_s132.zip" pre build zip file, it's working correctly. So just I wanted to know which command is used to generate the valid zip file.

Any help will be appreciated.

Thanks,

Raj

As seen in this link, I believe you only need to set NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS 0 in sdk_config.h. Then, compile the bootloader & continue like normal. Do everything else the same as explained in the secure dfu bootloader blog post (see Appendix 2 for more info).
