I am using ros melodic and mavros to run my offboard node. It should fly in a square trajectory, but it stays still.

When I try to run my offboard program, it instead runs the figure 8 which it should not because my own node is already running.

Using the voxl-vision-hub wizard I tried to set it to offboard modes 1,2, & 3 and neither worked. In mode 1 it did the figure 8 trajectory. In mode 3 px4 didn't let me switch into offboard mode. In mode 2 it just stayed there.

Here's my launch file:

Here is the part of my QGC log where it fails to move to offboard mode:

> offboard_mode

Check:
https://docs.modalai.com/mavros/#configure-voxl-vision-hub-localhost

offboard_mode - set to “off”. When offboard_mode is on, this enables voxl-vision-hub to command the drone to move, which we don’t want (we only want MAVROS to be sending movement commands)
