Connect SDK w/o nrfutils ?

[thomasklaush]

Can I use this library for firmware with nrf connect sdk?

When I build the firmware, a -zip is available, but the file does not work:

D/CompatibilityChangeReporter(17466): Compat change id reported: 160794467; UID 10485; state: ENABLED
W/DfuArchiveInputStream(17466): Manifest failed to be parsed. Did you add 
W/DfuArchiveInputStream(17466): -keep class no.nordicsemi.android.dfu.** { *; }
W/DfuArchiveInputStream(17466): to your proguard rules?

nrf utils is not working on Win11 (At least not on mine)
