Hi Alexey. I agree and will forward your feedback to the team.

It's better to have the meaningful message "Sorry, your HW is not supported", if possible.

Ok. This is the same reason as above. The chip inside this DK will not work with nRF connect.

You could fix this log message to something more descriptive like "chipset version is incompatible with nRFConnect" or something similar.

Hi Ketil, I am observing exactly the same behavior when connecting to PCA10068. strace shows that ttyACM0 can be opened: open("/dev/ttyACM0", O_RDWR|O_NOCTTY|O_NONBLOCK|O_SYNC|O_CLOEXEC) = 37

It seems that it scans /sys to associate the tty with USB (or something). [pid 10126] open("/sys/devices/pci0000:00/0000:00:06.0/usb1/1-2/1-2:1.0/tty/ttyACM0/uevent", O_RDONLY|O_CLOEXEC) = 37

Anyway the effect is the same as in the bug: "Not able to find /dev/ttyACM0" Is PCA10068 also not supported?

Hi,

PCA10000 is not supported in nRF Connect. Use PCA10031 if you want a dongle. Alternatively you may use any of the following DKs: PCA10028, PCA10040 or PCA10056.
