Hi I am trying to use C (not python) for RTDE for a UR10e. Can someone help me figure out how to pack the initial message, which I think should be 'v' for RTDE_GET_URCONTROL_VERSION. It says two bytes for the package size and 1 byte for the package type. I can open and connect thru the port but need help getting started with the basic header info in the first message I need to send. Can someone break this down for me? Is this sendmsg=8sendmsg=0 sendmsg='v' for the header info or am I way off base?
