I have a BeagleBone Green board running Debian. It uses Connman as the network manager.
The configuration file should be /etc/connman/main.conf however this doesn't exist.
I have two active network interfaces connecting to the internet, a wi-fi interface wlan0, and ethernet interface eth0.
Which interface takes preference / priority in this case when communicating to the outside world? Where is this configured if there is no /etc/connman/main.conf.
