DFU with bin file only

[kevin seo]

Hello,

I can create a zip file with nrfutil pkg generate and there is a bin file in it? I want to make DFU as a bin file only.

I only want to download the firmware as a bin file.

Is it possible?????

If it is possible, how can I download firmware only to a bin file?

And How to flow??????

Hi

The .dat file of a DFU contains the init packet. It contains information like firmware version, a hash of the image, signature, SoftDevice dependencies, etc.

The .JSON file is a configuration file used in DFU over TFTP and contains DEV_TYPE and DEV_ID for each firmware type, paths to init files, and paths to firmware images.

Best regards,

Simon
