Hi again, the problem is that p2os communicates with roscore, but the p2os_dashboard does not communicate with the p2os node. The p2os node connencts to the H8S board and, hence it is not a serial/usb port permission issue. If we run everything on the robot (roscore, dashboard, p2os) adjusting the ROS_MASTER_URI to localhost, then it works. But we would like to execute everything but p2os node on a remote machine.
