Connman does support AP and STA mode simultaneously but it strictly needs two different wifi chips or hardware. By creating a virtual wlan interface and trying the same functionality did not work for me, if only one chip is present - and did not dig in much deeper.

[PATCH] gsupplicant: add a callback after WPS start gets called
When WPS is used to connect a network, connect_callback should get called.
Before this change connect_callback was called only after non-WPS connection.
If WPS is used repeatedly, refcount continues increasing because this callback
is not called.
This causes that a network is not released properly.

RE: would it be possible some of technologies get online state simultaneously?
Hi Patrik
Thank you very much for your reply.
That is doable. With the Session API and its usage of session specific routing
tables, all session routing tables have the default route set.
The default routing table is the only one that has exactly one default route
set, this in order not to change the normal behavior if sessions are created.
Sorry Patrik. I didn't understand what this means. Do you mind explaining this
in more detail?
The 'online' state indicates that proxies are either not needed or
configured correctly for pacrunner,
http://git.kernel.org/cgit/network/connman/pacrunner.git/ Pacrunner
support is found in Fedora's libproxy package so that all applications using
libproxy will get the correct proxies and can connect successfully to
Internet.
But back to your original question, internet is reachable for the WiFi user
also in state 'ready'.
The problem here is wifi_user can't know the 'ready' status when the status
gets 'ready'.
I suppose Connman notifies only online/offline status. Therefore wifi_user
can't receive 'ready' notification from Connman.
Session_policy_local plugin doesn't set a route(ip route) when the status is
'ready'.
So in this case wifi_user can use ethernet.
I'd like ethernet_user to use only ethernet and wifi_user to use only wifi.
Could you tell me my misunderstanding if any.
Best Regards.

Cool!
Now the question is whether some of technologies get “online”
simultaneously.
Only one of the services can be 'online' at any one time. This applies both
for Session and Service APIs.
I’d like to configure available bearers per application (per user) by
using session_policy_local_plugin.
For instance while “etherner_user” is connecting to the internet via
Ethernet, “wifi_user” is connecting to the internet via WiFi.

ちょっと何言ってるかわからないです。
I think wifi_user’s session does not get online even if wifi internet
connection gets available.
I suppose that is because “ethernet” is preferred technology.
Actually, if ethernet is online, it means the connectivity check succeeded.
Ethernet could also have stayed as 'ready', should the connectivity check
have failed.
“wifi_user” can’t receive notification through session.
session_policy_local_plugin configure ip route when get “online”.
Therefore I think in above case “wifi_user” can’t connect to the
internet.
State 'ready' is enough to be connected to the internet. The difference
here is that 'online' provides a bit more information, it indicates that
the additional connectivity check to {ipv4,ipv6}.connman.net succeeded.
The 'online' state indicates that proxies are either not needed or
configured correctly for pacrunner,
http://git.kernel.org/cgit/network/connman/pacrunner.git/ Pacrunner
support is found in Fedora's libproxy package so that all applications using
libproxy will get the correct proxies and can connect successfully to
Internet.
But back to your original question, internet is reachable for the WiFi user
also in state 'ready'.
それはわかっています。問題は、stateがreadyでstayしたとき、wifi_user
がreadyステータスを知ることができないという事です。
また、session_policy_local pluginはreadyステータスではルートの設定(ip
route)をしないので、wifi_userはethernetを使用できてしまいます。
Ethernet_userにはethernetのみを、wifi_userにはwifiのみを使用させたい
のです。
Cheers,
Patrik

would it be possible some of technologies get online state simultaneously?
Hello all
I’m trying to use ConnMan to take care of network arbitration for my automotive
embedded system.
I had a question regarding session.
Now the question is whether some of technologies get “online” simultaneously.
I’d like to configure available bearers per application (per user) by using
session_policy_local_plugin.
For instance while “etherner_user” is connecting to the internet via Ethernet,
“wifi_user” is connecting to the internet via WiFi.
I’m expecting a usecase like this.
I think wifi_user’s session does not get online even if wifi internet
connection gets available.
I suppose that is because “ethernet” is preferred technology.
“wifi_user” can’t receive notification through session.
session_policy_local_plugin configure ip route when get “online”.
Therefore I think in above case “wifi_user” can’t connect to the internet.
Is my understanding correct?
If so, how can I realize above usecase?
Here are settings and logs for connmanctl.

question about wps pbc with any option
Hi All, I’m trying to connect to AP with wps pbc using connmanctl. I think when connecting to AP, we need to specify a service like “connect wifi_0123**”. Would it be possible to connect to AP without specifying service, just like “wps_pbc any” of “wpa_cli” ?

As far as I have confirmed by using scan APIs of wpa_supplicant, connman seems to receive the feedback from wpa_supplicant. When I use both connman APIs and wpe_supplicant APIs, is connman designed not to cause contradiction?
