Hi!

Thanks for the reply. I found out I cannot use iwd.py
without some modifications, and I couldn't run
test-runner, maybe because I used the kernel
that came packaged with the distribution (Arch).

For now, naxalnet only uses iwd to find out how many
devices are available, and starts an ad-hoc network
on the first device found. If there is a second device,
it starts an AP on it so that other devices can connect
to the mesh network without installing any software
just for joining the mesh.

So I'll just use the D-Bus API via python-dasbus.
 From test/list-devices I got some idea on
how to find all devices, and other things from
the other files.
