Yes, you can use the DFU example as reference and add DFU functionality to your existing project.

Thanks again !
I'm sorry, i forgot to add something ... When i was talking about adding files, i talked about my existing project.
To be clear, if i had .c, .h files and functions from DFU example to my existing project, will it work ?

Sincerely

Hi.

I don't know what you want to add to the example. But yes, the DFU example in the SDK will work.

Please take a look at the link in my previous answer (Configuring and performing DFU over Mesh). You can find detailed information about how to perform a DFU of your Mesh devices there.

Thanks for reply !
Just one more question :

I saw that there is an exemple of DFU in SDK file, and i presume that it's working with OTA. If i add functions and .c and .h files will it work ?

Sincerely

Hi.

1) Yes, you can update the devices in your Mesh network over the air.

2) Yes, packets that receive the DFU will also relay the DFU to other devices. That way you can update the entire network without having to move any nodes, as long as they are in range to another node.

3) The device will have to support DFU to be able to receive the update, yes.

4). Are you referring to the nRF52840 dongle? If yes, then the dongle will be able to support DFU.

You can read more in our online documentation:
