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
