Hello！

I am new to crazyswarm.
I have completed the installation and configuration, and then the following error occurred when running hover_swarm.

Thanks for the help!

This is likely optitrack related. Perhaps try the tips and code changes introduced in #364.

Thank you for your reply.
I have tried hover_swarm.launch on ubuntu 18.04 with ros melodic.
In addition, I have changed optitrack.cpp with reference to USC-ACTLab/libmotioncapture#11.

        for (int i=0; i < nMarkerSets; i++)
            {
              ptr += strlen(ptr) + 1;
              int nMarkers = 0; memcpy(&nMarkers, ptr, 4); ptr += 4;
              for(int j=0; j < nMarkers; j++)
              {
               ptr += 12;
              }

I also have installed NatNetSDKCrossplatform, the results of running natnettest and mcr are as follows

However, the same error still appeared.

At the same time, when I run mocap_helper. launch, the same error occurs.

Is there any way to solve these problems?
Thanks for your help.

[easy98]

I have the same issue, have you solved it?
