How to generate the Public keys to firmware application?

Even i am unable to install the nrfutil.exe for my windows 7? what could be the issue?

Tried pip install for the nrfutil-6.0.1.tar.gz using  command line "c:\ pip install ./downloads/nrfutil-6.0.1.tar.gz" still unable to install. Always getting below message

Please help me on nrfutil installation and public key generation for the DFU.

Hi,

It looks like the connection is timing out for some reason. Please try to use the nrfutil executable included in the release instead: https://github.com/NordicSemiconductor/pc-nrfutil/releases

Best regards,

I tried downloading the nrfuitl.exe, but its not installing. Scree shows the command line execution, but not installing.

On command line tried nrfutil --version, nothing is showing

Can you please post some screenshots that show the results of what you tried? You should be able to execute it directly from the command line without any installation.

I have tried below

1. python installation check

2. pip installation check

3. nrfutil installation check

4. tried to install nrfuti.6.0.1.tar.gz which is in my downloads folder

refer below for more

Thanks. The error is that it's not finding the executable. Please change the directory in the command line to the directory where you have stored nrfutil.exe.
