Great. Happy to hear that you're now able to successfully perform an application DFU. Which issue was it specifically? Is it listed in the pc-nrfutil repo issues, i.e. https://github.com/NordicSemiconductor/pc-nrfutil/issues?q=is%3Aissue+is%3Aclosed

Thanks a lot, now it worked ! It seems that v.6.1 has a little bug so my application could not work.

Hi Bjorn,

I use the nRF Connect for Android, there seems not to be a possibility for logging. I now will try v4.0.0 of nrfutil.

Hi Peter,

are you using the nRF Connect application on Android/iOS or nRF Connect for Desktop to perform the DFU? If so do you have the log from the application?

I also see that you are using nrfutil v6.1, I dont think that should be an issue, but could you try to use v4.0.0 when generating the firmware image and see if there is any difference?

Best regards

Bjørn
