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.

Ok, could you try to update your pip at first? I can successfully install pc-ble-driver-py==0.17.0 on my PC.
