Have been following the voxl cam setup guide but we keep getting the unable to communicate with master error.

What are the voxl cam's ros_master_uri and ros_ip supposed to be? what are they supposed to be on the host pc?

The goal is to get rviz running but we keep getting the "could not contact ros master at..." error.

is the command we need to use roscore on the voxl camera? the guide says roslaunch voxl_mpa_to_ros voxl_mpa_to_ros.launch but we get a different output than what the guide says.

rviz on pc? we found rosrun rviz rviz
