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.
# less /var/lib/connman/session_policy_local/ethernet_user.policy
[policy_ethernet_user]
uid = ethernet_user
AllowedBearers = ethernet
RoamingPolicy = forbidden
# less /var/lib/connman/session_policy_local/wifi_user.policy
[policy_wifi_user]
uid = wifi_user
AllowedBearers = wifi
RoamingPolicy = forbidden

It would be extremely helpful if I could receive some advice about this matter
