Oh, and I guess you meant extending net.connman.iwd.Device.Mode.  That can't 
really be done since Device maps to a netdev.  The choice of STA+AP vs STA-only 
would be on the wiphy level (net.connman.iwd.Adapter).

destroy -> reinitialize

You are correct. I miss to rebase on newer version

Okay, should be fixed now upstream with commit: a0017405064c ("manager: 
Initialize all default interfaces")

I'm not sure what you mean by 'they are not destroyed' though?

Ok

Anyway I have tested but it seems that it does not work for me.
Virtual node are there
but iwd pick one of them and they are not destroyed as you said

Ok, I think that iwd as interface is more easy to use then hostapd and having
one service is much more easy to work with.

Some hardware has the limitation to use only one channel
in this configuration. The idea is to able to decide to go on not go
in this configuration using dbus

I haven't looked into this in much detail.  I know nl80211 APIs do provide some 
information as to what interface combinations the hardware supports.  Not sure 
if/how it tells userspace about channel limitations.  If you know more, please 
share.

But yes, we probably would need to expose some of this info via D-Bus or teach 
AccessPoint.Start/StartProfile to only use the active STA channel if the 
hardware has such limitations.

Right.  Since most people want to use iwd + hostapd for such tethering cases, we 
made the decision to simply ignore any new devices created outside iwd after a 
wiphy has been initialized.

You can get around this by creating the sta + ap devices first, then starting 
iwd.  You'll need to set UseDefaultInterface=true in /etc/iwd/main.conf.  See 
'man 5 iwd.config' for more details.

Teaching iwd to create STA + AP interfaces when it initializes an adapter is on 
the TODO list.  We already do this with P2P, but not STA + AP.  This should be 
fairly easy to do, but we have been busy with other tasks.  Patches are always 
welcome!

Our (preliminary) thinking on this was to add a main.conf entry that tells iwd 
how it should manage wiphys by default.  Something like: "sta-only", "sta+p2p", 
"sta+ap".  Based on the configured setting, iwd would then create the interfaces 
automagically (assuming hardware/driver supports it,  falling back to "sta-only" 
if not).

iwd access point mode

[Michael Nazzareno Trimarchi]

[-- Attachment #1: Type: text/plain, Size: 442 bytes --]

HI all

I'm playing with iwd. Looking at iwmon I can see virtual device
discovered by iwd when they are created.

iw phy phy0 interface add wlan1 __ap

iwctl still report wlan0

 I was able to create wifi connection and access point mode using
wpa_supplicant and NetworkManager. My idea
is was experimenting iwd

iwctl device list still report only wlan1. The idea behind is to
control ap+sta interface. Any feedback?

Michael
