Problems with cf.position()

[Ogglan]

Hi!

I am currently doing a project based off the CrazySwarm at my university.

We encountered a problem whilst trying to create a live visualization of the drones, where the idea was to compare the drone positions to the chosen path (or "ground truth") during flight.

To update the visualization the cf.position() function is used, which worked when we were manually moving the drone in the mocap area. The problem occurs when a mission is run (figure8_csv.py for example) whilst the visualization is active, then the cf.position() stops returning new pose estimates and the visualization comes to a halt.

Has anyone encountered a similar problem or know how to solve this?

Thanks in advance :)
