i have two nodes 1) which receives CAN messages from uc board to ROS (publisher) 2) which transmit CAN messages to uc board (subscribing). I need to run both the nodes in order to to these two tasks. Now I am supposed to do: if receive node receives message, it should transmit a CAN message. How can I combine these two nodes or how can use one node information by other?. any suggestions

you could implement the nodes as nodleds understand then nor those in an node, or you define a new topic which is your sync signal. if you receive a can message then you publisch to the sync topic and if the send node receive a sysnc topic then you write your CAN message.
