Unable to contact master


#1

I am not able to contact the ros master after powering up the computer 9/10 times.

After turning on the vehicle I will double click the rviz/ rqt applications and nothing will appear in the plots.

Running rosnode list in the terminal returns an error stating that it is not able to contact the master.

I will be flashing the computer using the usb method.

Did you run
export ROS_MASTER_URI=http://192.168.45.1:11311
export ROS_HOSTNAME=$(hostname).local
?
