Okay. Suppose I have one hex file and I am creating zip package using command nrfutil pkg generate --hw-version 52 --application-version 1 --application nrf52832_xxaa.hex --sd-req 0x98 --key-file private.key app_dfu_package.zip Now what changes should I make in the code so that I can upload this zip package using nrf connect app? Or lets say I want to combine ble_app_gls and secure_bootloader.

The example I sent you earlier includes the Buttonless extention, which enables the application to jump to the bootloader when receiving a DFU start command over BLE. Everything related to the actual DFU process is handled in the bootloader, not in the application.

I am not modifying bootloader_secure project. I am referring this project and modifying the code that you sent me. Earlier I was in discussion with Hung for the link that you mentioned. I had successfully generated the key files as well as the zip file for the project bootloader_secure. But my concern is how should I add the dfu_public_key.c file in the code that you sent me? Do I need to add any other files in the code that you sent me?

You don't need to modify the bootloader_secure project to support buttonless DFU. Please try to follow the steps in Hung's blog post that I linked to earlier.

Hi Vidar, I am extremely confused in bootloader and secure ota. How to include boot loader to support secure dfu? I can see nrf_dfu_settings file in nrf_bootloader. Is this the file that you are talking about?

The example I sent you includes the Buttonless extention, which does not handle the DFU process itself. You need to include the bootloader to support our secure DFU feature.

Hi Vidar, Actually I want to upload my new application file via secure ota through app.So to use commands I need to include key files in my project. So what changes should I make in the code that you sent me? Thanks, Shailav

Forgot to give you the link to Hung's blog post, which is a supplement to the existing documentation and explains how you can perform OTA update: https://devzone.nordicsemi.com/blogs/1085/getting-started-with-nordics-secure-dfu-bootloader/

Hi, Suppose I want to update my nrf firmware over the air so can I use the code that you send you? As it has device firmware update service. For example there is one existing firmware on my nrf kit and now I want to update new firmware through nrf app so what should I do?

Bootloader in SDK 12.2.0 will only accept signed FW images. The code I sent you earlier was for the buttonless part (i.e., jump from application to bootloader), and not related the dfu process itself.

Recommend to read the following documentation to get an overview of the new DFU feature:

Hello, But I am not using secure ble so why do I need to create my own key? If I am creating my own keys how to add files to my code? I am using the same code that you sent me. Thanks

Hello, you need to create your own key pair with nrfutil, please refer to the documentation here (link) for more details.
