You can connect multiple networks in different and the same technology, but we have not automatic handling of. Do I do this through the net.connman.Service.Connect() method? Yes, any other services need to be connected manually. If the manually connected service goes to state 'online' with the current one in state 'ready', the online service will be used as the default route out. If I manually connect an Ethernet service, and it is plugged in, does that downgrade all the other services to ready? Only if all the other services had stayed in state 'ready'. My understanding is that connman automatically falls back to link local (RFC 3927) if it fails DHCP. How does that work when 1 DHCP service fails DHCP? Good question, I'd have to read the code thoroughly to answer that one. Now, there is the exception to autoconnect, and it's called 'PreferredTechnologies'. When set, ConnMan will alter the normal autoconnect order as specified with that setting. If e.g. ethernet is configured and connected later (cable plugged in), ConnMan will autoconnect ethernet. If the preferred connection goes 'online', it will be used as the default route and any previous 'online' connection is downgraded to 'ready'.

does Connman handle multiple connections at once?
Hi Jukka Patrik: By default connman only autoconnects to one service at a time. If you set /etc/connman/main.conf file (see example file at src/main.conf) setting PreferredTechnologies=ethernet,wifi then you might get both ethernet and wifi autoconnected at the same time. There is some exceptions like if the ethernet Sorry, I'm still a little bit fuzzy on the connman's paradigm. Does connman, by design, only automatically bring up (meaning, the online state) one service (i.e., the one on top of the list), and implement its IP configuration?

Re: does Connman handle multiple connections at once?
Jukka, I did try putting PreferredTechnologies=**ethernet,wifi, but still only one connection was established. Is there a way to force multiple connections at once? I'm trying to understand the source code, and it's not obvious to me where the code decides only to retrieve a DHCP address from one interface.

This is a possible outcome, yes. Both ethernet and wifi will be connected only if ethernet ends up in state 'ready' with wifi being either 'ready' or 'online'. Is there a way to force multiple connections at once? ConnMan is happy with one connected connection (no PreferredTechnologies set) or with multiple ones depending on the ordering of PreferredTechnologies and the order in which technologies appear. If some really specific connections are needed, they need to be connected via user interaction over D-Bus.
