Not able to communicate to mater


#1

Hey guys,

I ran into a problem working directly on the slamdunk. When it is not connected to wifi,nodes are not abe to contact the master. Could some give me an idea as to where the IP is exported?

I tried sudo start slamdunk_ros_node ,it said it was already running. However when I tried rosnode list, it said could not contact with master. /opt/ros-slamdunk/setup.bash was already sourced.

echo $ROS_MASTER_URI gives http:/localhost:11311.

Could this have anything to do with a previous issue I posted ?http://forum.developer.parrot.com/t/not-able-to-connect-to-slamdunk-over-usb/5371

Thanks
