Hi James,

From SDK v7.0 the init packet is required. So you would need either to provide the .dat file (as showed in the app after you select the .hex) or you need to generate and provide the .zip file. I would suggest to use the .zip file (can be generated by nrfutil.exe) .

You can read more about different version of the DFU bootloader here.
