ROS mocap_optitrack version problem

When I launch

Code: Select all

roslaunch mocap_optitrack mocap.launch
, it says that "[WARN]: could not get server version, using auto." I launched this file in the terminal, whose ROS_MASTER is set to another address. I'm not sure if it is because I must launch this file directly on the master, no mocap related topics show up except for

Code: Select all

/mocap_node/optitrack_config/parameter_descriptions
or

Code: Select all

/mocap_node/optitrack_config/parameter_updates
are visible in the rostopic list. However, if I launch this file on the master terminal, the names of the related topics are visible by

Code: Select all

rostopic list
now, but no data is streaming out. What could be the possible reasons and solutions?
