regarding bootloader with setting for DFU

[roger.k]

Hi. I'm using nRF52832, SDK13.0.0, S132.

When I make bootloader, I should make *.setting file for application.

Do i need *.setting file when I update just application file through DFU?

As I've tested, even I just updated application file, it works well. I'm so confused. Because although I didn't update bootloader's setting file for application, why is it working well?

I need your reply.

The bootloader settings must be present in the last page of flash in order for the bootloader to function correctly. The settings file is only required when you are flashing the bootloader. For any subsequent application updates through the bootloader, the settings file is not required.

Hi Roger,

Why do you need to generate bootloader setting hex file ? Could you point me to the documentation page causing confusion ?
