Cannot see the formation of vicon

[Allenhanbo]

After I clone and catkin_make the vicon_briage directory in my workspace, I set my PC's which running vicon hostname to vicon. And then I roslaunch the launch file vicon.launch, but there's no reaction. The situation like this:
ardrone@ubuntu:~/crazyflie_ws/src/vicon_bridge/launch$ roslaunch vicon.launch
... logging to /home/ardrone/.ros/log/e3ebe690-ea24-11e9-bc46-000c29a0daf3/roslaunch-ubuntu-6801.log
Checking log directory for disk usage. This may take awhile.

I guess the problem is in your "datastream_hostport" parameter in "vicon.launch".

I guess yours is "vicon:192.168.10.1". Could you try to change it to "192.168.10.1:801"?
