grab frame returned false problem with vicon ROS Indigo
Hi,
I am trying to connect vicon with ros inidgo but I am getting the following error:

when I changed the port number to 801 or delete it (I kept the ip address only ), getFrame returned false was gone. However, I still had a problem as shown below

the last line lasts forever.
At this stage, the package is working very well, but I was not able to read from (viconbridge/Markers) topic. I got the following after I type "rostopic show /viconbridge/Markers" : Are your messages built?. The problem was solved after I sourced the shell to "devel/setup.sh" and then type "rostopic show /vicon_bridge/Markers." Everything is OK now.
Any help/advice please?
Thanks in advance,

Have you found the solution to this problem? I am experiencing the same thing with my project.

The solution is written in the post. Please read the whole post, and if you still have a problem, please write what you get on terminal.

Thanks for the quick reply. I don't think that show is a valid rostopic command, correct? I sourced the shell using source devel/setup.sh in the ~/catkin_ws/ directory. When I execute rostopic show /vicon_bridge/Markers, it just shows a list all of rostopic's commands that does not include show.

You are right. I think I wanted to write rostopic echo instead of rostopic show. Anyway you should be able to subscribe to this topic and read the data, or you can create your own object (https://youtu.be/dGMwVMiX7-I?t=26) and subscribe to it.

I think I might know what my problem is. It seems that you have the vicon sdk 1.5 installed. I have the 1.3. How did you update yours?
Asked by rahulROS on 2016-08-11 14:49:19 UTC
I downloaded sdk 1.5 form vicon website (https://www.vicon.com/downloads/utilities-and-sdks/datastream-sdk/vicon-linux-datastream-sdk-15) and then replace the one that is inside the vicon package.
Asked by Moha89 on 2016-08-11 15:51:51 UTC
did you have to change any files such as the CMakesLists.txt?
Asked by rahulROS on 2016-08-11 15:59:45 UTC
No. As I remember, I just replaced the sdk inside vicon package.
