dfu version in .zip file

[Raj]

Hi, In my project I am using nrfutil.exe tool to create a .zip by using the following command

nrfutil.exe dfu genpkg j1.zip --application application_nrf51822_xxac.bin --application-version 0xFF --dev-revision 0xff --dev-type 0xff --sd-req 0xfffe.

In zip their is a file manifest.json the content in the file is

{ "manifest": {

    "application": {
        "bin_file": "nrf51422_xxac_s130.bin",
        "dat_file": "nrf51422_xxac_s130.dat",
        "init_packet_data": {
            "application_version": 255,
            "device_revision": 65535,
            "device_type": 65535,
            "firmware_crc16": 22333,
            "softdevice_req": [
                65534
            ]
        }
    },
    "dfu_version": 0.5
}

}

In these file I want to change the "dfu_version". but their is no argument for dfu_version in command mentioned above. If I try to change manually its not working. can any one tell me how to change the dfu_version.

Hi, I got the solution for it. By using --dfu-ver parameter in command we can change the dfu version number i.e dfu_version. But it accepts only float values.

Raj, Why did you need to change the dfu_version in the .zip file in the first place? thanks, Sam
