I have a BU-353s4 GPS and I am getting this error when trying to start navsat_driver:

socket.error: [Errno 111] Connection refused

I have verified that I am a member of the Dialout group:

And also have checked my ROS ENV variables:

  • ROS_ROOT=/opt/ros/kinetic/share/ros
  • ROS_PACKAGE_PATH=/home/rosmachine/catkin_ws/src:/opt/ros/kinetic/share
  • ROS_MASTER_URI=http://localhost:11311
  • ROS_HOSTNAME=localhost
  • ROSLISP_PACKAGE_DIRECTORIES=/home/rosmachine/catkin_ws/devel/share/common-lisp
  • ROS_DISTRO=kinetic
  • ROS_ETC_DIR=/opt/ros/kinetic/etc/ros

"started roscore service and echo'ed [/rosout]" no errors

I can connect to the usb port "/dev/ttyUSB0" and see nmea data with minicom.

Any ideas?

I'm not sure this is an error with opening the serial/usb port: socket.error seems like something with tcp/udp sockets, not serial ports.

That may be a red-herring though, as I haven't used this pkg myself.

Yes, this was an issue on my local computer. Tried on another and it works correctly.
