Just a suggestion based on my use case.

The top level function raises exceptions for different kinds of failures.

Specifically, the 'NordicSemiException' generates descriptive error messages but those are quite verbose and different to match even with regular expressions.

However, this class also has the attribute ErrorCode which is currently always set to 'None'. It would be helpful if this attribute could be updated with perhaps some integral values to designate specific errors so that the callee can quickly distinguish betwee the error conditions and take corrective action.

Good to hear. Thanks for confirming that it worked.

Disabling the Mass Storage Device seems to work. Just one note though that the JLink for ARM is different from JLink for Linux-32 bit (which is what I tried initially but got an architecture mismatch).

Thanks for all your help, Vidar.

I was doing DFU with nrfutil v.6.1.0 and everything appeared to be stable. However, I was using the nRF52840 Dongle with the built-in nRF USB and not a dev kit with the J-link USB. Have you disabled the Mass Storage class on your J-link: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/guides/tools/nordic_segger.html#nordic-segger-msd?

Have a follow up question.
I am now able to get my Raspberry Pi to talk to the nRF52 DK board and have it discover a remote device that I want to update using the Nordic DFU protocol.

I have been able to make this happen on a windows platform i.e. the DK has the appropriate 'connectivity firmware'. With the Pi, however, the DK board is not able to sustain the connection and execute the DFU. Initially it had an issue with the MTU (which I then overrode and set to 123). Then, it went past the point where it negotiates the MTU etc. but failed to transfer the 'init packet' with this stack trace....

Thanks Vidar. This package seems to progress further upstream and does show that it is using the API version 5 as required for the NRF52 DK (with nRF52832).
Would it be possible to 'release' this out in Nordic's GitHub playground or somewhere similar?

Cheers

Please try to install the wheel package of the pc-ble-driver-py module below and see if you still get the same nrfutil error after.

This is one I have built myself on a Pi4, but I don't recall if I tested it with the latest version of nrfutil or not.

I followed all the steps (except adding the '-U' as a command line option in the last command in step 6).

But I still get the error indicated in my original post.

More importantly, your answer does not quite give me the correct 'version' of the API to link to.

Hello,

I was able to install nrfutil on my RPi 4 by following the step 6 under the Configuring a Co-Processor chapter.

Kind regards,
Øyvind
