Workflow for DFU via BLE on Windows

Hi again. I missed your question a bit and I apologize for the confusion.

1. The nRF Util for nRF5 SDK only supported dfu created by nRF5 SDK and not a project created by nRF Connect SDK

2 & 3. Currently FOTA is not supported in windows and you will have to use either linux, osx, or android/iOS

One alternativ for linux would be to look into MCUmgr-cli https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/services/device_mgmt/mcumgr.html

Hi Runar,

VSCode generates dfu_application.zip in the build folder. Are you saying this is the file that's actually supposed to be used with nrfutil? What do I need to change in my setup for it to work? nrfutil complains with the following error when trying to update with this file:

KeyError: 'manifest'

When generating the package file 'manually', the manifest in the zip file is different. By manual, I mean I created the package file using nrfutil. I'm confused with what this package file actually needs to contain, so I wouldn't be surprised if what I tried for testing is wrong:

nrfutil pkg generate --hw-version 52 --sd-req 0x123 --application-version 4 --application app_signed.hex dfu.zip

I would really appreciate if VSCode would just output the correct file without me having to dig into this.

Regarding the dongle, yes, I've put it into bootloader mode before programming. My device connects, it lists all my services and I evencan read/write my characteristics. So I assume the dongle is correctly programmed?

Hi.

1. I will need to look into this.

Have you managed to create the dfu_application.zip from Vscode? Here is an overview over different output files and their use developer.nordicsemi.com/.../index.html

2. I will need to look into this.

3. Did you follow the procedure as written her: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf52840_dongle%2FUG%2Fnrf52840_Dongle%2Fprogramming.html to set the dongle in bootloader mode before trying to program it using the nRF Connect for Desktop Programmer?
