nrfutil not working on M1

[Constantin]

Hi,

I am using a M1 and I've installed the flashing scripts. But I am getting the following errors.

As I've already figured out it is a bug in https://github.com/NordicSemiconductor/pc-ble-driver/pull/271

And although it is merged into the master it is still not available via pip3. Any other solution to get the bug fix?

Kind regards,

C.W.

Hello Constantin,

Sorry about the delay. I am looking into it.

Hi Constantin,

This looks like a python library compatibility issue. Have you tried the solution mentioned in NameError: global name 'xrange' is not defined in Python 3 - Stack Overflow?

Best regards,
Charlie

Hi Charlie, I mean there is already a merge request and solution to this issues. The only problem is that nordic did not yet pushed this solution to the pip sources. Hence, if I install it via pip I am getting the errors. The version currently available at pip is still 2-3 years old. Kind regards, Constantin

Hi Constantin,

Similar to nRF5 SDK, the current pc-ble-driver is in a maintenance state now, so I cannot promise there will be an update but I will forward your feedback to our development team.

We have most of the resources focusing on new solution development based on the nRF Connect SDK now. A potential alternative is the following sample, so developers can send commands directly or through scripts to control the BLE device running this firmware.

Best regards,

Sorry, but we already in production state and we need the toolbox to build up the merged firmware files between softdevice and firmware. I do get your point where the connect App should work in this point?
