Thank you very much for your quick reply !

I'm using the nRF5 SDK, I will check out the corresponding guide.

I'm using Arch Linux and I have some issues when using the downloaded NRF Tools, but I will try with pip!

Hi Théo,

[quote user=""]I have a working firmware and I want to implement DFU OTA on it but I can't find any documentation for getting started to add DFU on an existing application.[/quote]

We provide two distinct SDKs, the nRF Connect SDK and nRF5 SDK. Which are you using? Both provide DFU support. If you are using the nRF Connect SDK, then I suggest referring to this tutorial to get started: Add DFU support to your application. If using the nRF5 SDK, you can refer to this one: Getting started with Nordic's Secure DFU bootloader, a step by step guide.

[quote user=""]I can't use the nrfutil tool as it doesn't work on Linux.[/quote]

nrfutil can also work on Linux. We test on Ubuntu but it should also work on most other distributions. You can install it via pip ("pip install nrfutil").

[quote user=""]And do nrf52832 have a default bootload with DFU OTA out of the box ? To avoid flashing everything by hand with a cable.[/quote]

No, all nRF5 devices ship with an empty flash.
