I was trying to have a connection to the 3 quad defined in the multi vehicle simulation.
I read the launch file, and started the mavros nodes with roslaunch, according to the [info] coming from the px4 I should use the port 14581 14582 14583. However all of them are already in use
I have also tried with another addresses, just in case missed up something.
Also, reading the comments at the end of the Firmware/launch/multi_uav_mavros_sitl.launch in the master version, it indicate about using 1455x numbers which are not declared at all in the files
