I have just come across the same error two years later: "Error: [hci0]:
can't init hci: can't down device: operation not permitted".
Giving the utility the CAP_NET_ADMIN capability worked for me; once you do
so, the user does not need to be in sudoers when running the utility. To do so,
I did the following under debian Bookworm. You'll need to run these commands as
root, replacing the path with your installation location.
apt-get install libcap2-bin
setcap 'cap_net_admin=ep' /home/dev/go/bin/mcumgr
Could this capability be granted by the installer, or a warning given if a
non-root user installs it? The error message alone does not make obvious what
the solution should be, and I spent a lot of time trying to add my user to
various groups for instance, under the assumption it was a permissions issue.
Thanks.
