DFU Init file structure

[Alexandar]

Hello,

is there any documentation about DFU init file structure (SDK 14.0)? I used NRF util for creating DFU package, but i want to create my own app for that purpose.

Hi Alexander,

The Init packet structure is defined by a Protocol Buffer (.proto) file, found under nordicsemi/dfu/dfu-cc.proto in the nrfutil folder.

There is a guide on how to customize the init packet in the nrfutil documentation, see this Infocenter page.

Thank you.
