Backup mavlink

Hello folks.
We are flying our Go Discover with Navio+ via 4G now.
Last flight was 28km and everything is working great.
However, we are interested of having backup mavlink channel in case when 4G drops. As I understand, apm can be started with two mavlink connections. Is it possible to configure secondary connection to udp and different ip address - the same goundsation but on wifi network?
What happens when both interfaces are connected on same time?

It should work just fine:)
We always use wifi+radio, it won’t be much different in your case.
Just specify different IP addresses using -A and -C arguments.
