rostopic echo doesn't output data

edit

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.
