Hi ,

I would like to know if the .dat file inside the DFU packet is always the same or it can be different.

Is it Possible to fix inside the code ?

What is the .dat file contains ?

Thanks ,

Hi Luca,

the .dat file inside the DFU .zip file contains the init packet. You can also refer to Customizing the init packet in the nrfutil documentation. As you can see from the documentation, the init packet will depend on the image you are updating, since it contains information like firmware version, hash of the image, signature, SoftDevice dependencies, etc.
