RTDE functions return empty vectors (sometimes)
I have the following issue: after establishing a connection to the robot, and using the interface several times for several operations, suddenly, when calling for some of the RTDE functions like "getInverseKinematics", "PoseTrans", "getForwardKinematics" - an empty vector is returned (apparently the "sendCommand" function is returning false). Do you know why could this happen? what can I try?
several notes:
- I'm using the simulator, haven't tried yet on real robot
- sometimes, calling 'reuploadScript' is helping
- i'm using simultaneously the 'control', 'receive', 'io' and 'dashboard' interfaces
