Hello all ! I am using Hydro version of ROS. I have created a node in which I made a variable and store the value in it. Now I have to pass that variable value to another node. So that it can access it. Can any body tell me how I can do the above thing. I am working on python so it would be nice if anybody tells me in python Thanks Looking forward for answers !
