Hi,
I've spent the last few days trying to get this going and getting super frustrated.
After having no luck getting the nrfutil to work on Python (another thread) even switched to another machine. That didn't work either another series of Python faults.
Gave up on using OSX for this.
Switched to a Windows machine, that wouldn't install the nrfutil tools.
Switched to ANOTHER windows VM, finally got it installed.
Created a zip file using the tool.
Trying to use the latest Android NRF tools to do the DFU upgrade.
Just gets stuck with the update.zip (created using the NRFutil tool on windows VM), shows nothing in the NRF Logger. Just after selecting blips straight back.
Try sending the application.hex separately, it requires the .dat file, so I extracted that from the update.zip and used that.
The tool just keeps looping and showing the same modal about selecting the .dat file. Since theres a drop shadow on that modal I see it getting darker and darker and it's just stacking up modals.
The whole scenario is totally messed up and not working at all.
This is the worst experience I've had with Nordic stuff over the last 3 years just wasting days and days on pointless stuff that should be no problem at all.
The boot loader is the latest boot loader, SDK 11, using the DFU 0.8
