hover_swarm.launch and mocap_helper.launch does not output Motive data

[pthinesh]

I am trying to fly one Crazyflie using hover_swarm.launch with OptiTrack motion capture system. Everything works fine, except that rviz not showing the Crazyflie movements.
There were no errors in the terminal. I also tried mocap_helper.launch, there are no position updates printed.

I made the following modifications in "hover_swarm.launch" file:
motion_capture_type: "optitrack" # one of none,vicon,optitrack,qualisys,vrpn
object_tracking_type: "motionCapture" # one of motionCapture,libobjecttracker
send_position_only: False # set to False to send position+orientation; set to True to send position only
# vicon_host_name: "vicon"
optitrack_host_name: "192.168.1.1" # Windows (Motive) IP address
# qualisys_host_name: "10.0.5.219"
# qualisys_base_port: 22222
# vrpn_host_name: "192.168.1.1"
optitrack_local_ip: "192.168.1.3" # Ubuntu IP address
optitrack_server_ip: "192.168.1.1" # Windows (Motive) IP address

Motive Streaming settings:

Terminal output when running hello_world.py with hover_swarm.launch:
(Crazyflie takes off and lands without any error)

Terminal output when running mocap_helper.launch:

I'm using ROS noetic on Ubuntu 20.04.
Motive version is 2.1.2
Windows and Ubuntu are connected using a separate Ethernet port, and there are no problem with the network (motion data are successfully received when using VRPN).

Could you try running https://github.com/whoenig/NatNetSDKCrossplatform and report if you can receive data that way?

Hi @whoenig, Thanks for the reply.

I tried 'NatNetSDKCrossplatform'; following is the output

Then again I tried VRPN (it works without any error)

Hi @whoenig, I tried disconnecting the Wifi and run hover_swarm.launch, following error occurred;

VRPN works fine.
I couldn't find the mistake, could you help me resolve this?

See whoenig/NatNetSDKCrossplatform#2.
