I am studying how to use Robotics System Toolbox in Matlab 2016a. I setup the program in two separate computers: one is a single board computer (Ubuntu 14.04, IP 10.10.10.101), and one is a laptop with Matlab (Window 7, IP 10.10.10.102). I used wifi for the communication. I have an issue with the network setup and I hope that you could help me to figure out.
I run roscore and a node in single board computer to collect data from an IMU and the following commands to setup the ROS_IP and ROS_MASTR_URI:
And in Matlab, I declare the following command to setup the connection:
Then, I run “rostopic list” to check the connection and it shows all topics. However, when I run “rostopic echo” it does not display any data. I cannot use "receive" to get data either. I have verified the network connection by successfully sending the ping signals between two computers.
Do I miss any step?
Thank you for your help
