2017-04-01 18:16:09 -0500 | asked a question | rostopic echo doesn't output data Hello, I am trying to access the the /vislam/pose data using: https://github.com/ATLFlight/ros-exam... I am running ROS on the snapdragon flight. ifconfig yields an IP of: inet addr:192.168.0.111 i have set ROS_IP, ROS_MASTER_URI, and ROS_HOSTNAME in the /home/linaro/.bashrc file as so: export ROS_HOSTNAME=$(hostname -I | awk '{print $1}') export ROS_IP=$(hostname -I | awk '{print $1}') # Set ROS_IP export ROS_MASTER_URI=http://192.168.0.111:11311 and env | grep ROS yields: ROS_ROOT=/opt/ros/indigo/share/ros ROS_PACKAGE_PATH=/home/linaro/ros_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks ROS_MASTER_URI=http://192.168.0.111:11311 ROS_HOSTNAME=192.168.0.111 ROSLISP_PACKAGE_DIRECTORIES=/home/linaro/ros_ws/devel/share/common-lisp ROS_DISTRO=indigo ROS_IP=192.168.0.111 ROS_ETC_DIR=/opt/ros/indigo/etc/ros I have added this IP in the etc/hosts file as so: 192.168.0.111 test1 The IMU is properly outputting data according to the sensor tester (see github documentation) and rostopic list yields: /rosout /rosout_agg /vislam/odometry /vislam/pose However rostopic echo /vislam/pose yields a blinking cursor on a blank line. If there is anything I have done incorrectly or more information needed, please let me know. Any help would be sincerely appreciated. |
