You can look into message_filters package. This package filters messages from more than one subscribed topics and passes it to a single call back. All the subscribed topics need to have a time_stamp, for this to work.

I may not be of help here. I do not use ROS on arduino.

I haven't tried to create several callbacks but you can remap the different topics to a single topic in the launch file and process them with a single subscriber.

Hi thanks for your answer. I am creating rosserial subscribers on Arduino. It works fine with several callbacks, but I am looking for single callback. Any example? Is it available in ros arduino documentation?
