Hello,

I think I am having issues connecting MAVROS and MAVLink to PX4. I entered in `voxl2:/$ rostopic echo /mavros/state` and got the following result:
`
header: 
  seq: 0
  stamp: 
    secs: 1718964556
    nsecs: 273377842
  frame_id: ''
connected: False
armed: False
guided: False
manual_input: False
mode: ''
system_status: 0
---
`

What is the issue? Is this port related? Which configuration file do I need to edit? Thanks!
