nrfutil dfu ble seems to fail suddenly.

[David Fernandez]

It was working a few times, then suddenly I started to get these errors, which I only got previously when not running as root (perhaps because it did not have permission to open the serial port), but now it happens all the time.

I have rebooted, and still the same.

I have tried to open the serial port with minicom and it works, seems to be sending the same few bytes every half a second.

I have installed the nrfutil with:

# pip install intelhex

# pip install nrfutil

Never a problem, and did not change anything...

So no idea why... Help would be greatly appreciatted as it is urgent to get that working again.

# nrfutil dfu ble -p /dev/ttyACM0 -ic NRF52 -pkg /home/david.fernandez/src_mgt/rowesolutions/Doorlock/_build/DoorlockFull_dfu.zip

Those folders do not contain anything... that is why running it fails... Maybe that is the problem with the module you provided... it does not install the required libraries there, like the mainstream installer do.

[Susheel Nuguru]

Sorry David, we saw that build only included the Windows drivers and missed the Linux files. We have initiated a new build to include Linux drivers and will include that here as soon as it builds.

[David Fernandez]

Awesome!

[Susheel Nuguru]

The driver for linux is being submitted to pip just now. Can you do pip install like below

pip uninstall pc-ble-driver-py

pip install pc-ble-driver-py

and verify that version 0.11.4 gets installed.

[David Fernandez]

Done:

# pip install pc-ble-driver-py

Still get the same problem:
