Problem viztracker values

[befl0]

Hi,

I used a tracker with a vrpn. Sometimes when I do a tracker.getData() and I put it in 8 values, a mistake appears because there are " too many values to unpack" but sometimes it's working perfectly. I realy don't understand why and where I can fixed the problem. I think it's a problem of connection but I am not sure. If you can help me how to find the solution.

Thanks,
