The only thing you need to do is to extend the wifi.c plugin to set to
SAE if it's available when PSK is selected via the D-Bus API. As Marcel
pointed out this should not be exposed to the user.

So do you know how this works, exactly?

Daniel or Marcel can correct me if I'm wrong, but I don't think this is a
usecase connman supports. Tethering is just that, sharing your
ethernet/wwan/whatever connection over wifi.

So I think there are two ways of doing this:
1. Being able to scan while in AP mode. This is something that has been
brought
up before as desirable, etc. But no one has made any contributions just yet.
All this does is lets you see the surrounding SSIDs...
2. Use multiple interfaces if your hw supports them. So 1 interface in AP
mode,
the other in station mode. Then you could connect to the headless device on
the
ap interface and run iwd on the station interface as usual to set up the
network.
In theory 2 can be done today, either by iwd or combo iwd/hostapd with some
manual magic.

You are right. ConnMan does not support AP mode. There is no D-Bus API
exposing the AP mode of an WiFi interface. ConnMan does not expose
devices either, so it's not something we could just add.
Thanks,
Daniel
