Thanks for the response. Can this be accomplished by user trying to
disconnect with the service. In that case the another connected services's
gateway becomes's the default gateway. The only problem here would be that
that auto-connect/favorite flag for the service would be turned off once
the disconnect is issued. So user may have to issue connect again. In short
this is the sequence:
1) Connected with service A (tech A) and Service B (tech B) and default
route is via tech A.
2) We want to change the default route via tech B.
3) Issue a disconnect to service A
4) This disconnect would trigger the change and connman would make default
route via tech B
5) Wait for that to happen
6) Issue a connect to service A again (as we still want service A to be
auto-connect)
What if user decides to bypass connman and directly change the default
route/gateway (using some ip command). Will that have any side effects on
connman?
Regards
Naveen
