Python version of simROS: Can't call subscribe function

[fferri]

Yes I understand that, but rospy.spin_once() does not exist. rospy spins up another thread for each subscriber so spin_once is not necessary, and the function does not exist in the rospy library. roscpp works in a different way, and does have spin_once available, but not rospy.

You are right. I looked for "rospy spin_once" but I might have found some solution that was meant for ROS2 instead.

I am facing the same issue from my side with everything similar in regards to the software versions. Is there a solution to this or should I just use Lua ?
