I'm looking for a network manager.
I would like to use ConnMan in an embedded system. It seems that it
provides most of the features I'm looking for, including 3G and VPN
But after some research it seems that there is maybe one missing
point in it. Let say I have the following setup :
- Ethernet connection as preferred connection
- 3/4G connection as backup/failover connection
My Ethernet is always on and dhcp server is properly providing IP,
cable is still plugged in, and power on the line is still there, but
sometimes the internet connectivity is lost. So in that case it ll
switch to the 3G/4G connection. But then as soon as possible, when
connectivity is back online via the ethernet, I want to switch back
to it for performance and cost reason.
Is this supported by default, or is there a way to configure it that
I found this
which seems to say that it was not supported at that time, since
there is no periodic check (February 2013).
And also from the documentation :
Favorite (saved) networks that have autoconnect enabled are
considered when autoconnecting services. These services are marked
with '*' and 'A' in connmanctl, respectively. By default ConnMan
autoconnects these in the order they are shown in the list of
services until one of them gets connected. After that the
autoconnected service is in use and ConnMan won't select a new one
until the network goes out of range. When the service goes out of
range or gets disconnected from the network infrastructure side,
autoconnect is re-run and another favorite autoconnectable service
So I want to make sure I got the correct understanding on that ?
Feel free to ask for more informations if this is unclear.
Thanks for your support,
