Hello everyone!

I have a problem using this driver
Can't see the messages with "roll" "pitch" and "yaw" angles information (in degrees, as i says in msg/Ins.msg file)

My device is VN100
according to this I've modified /launch/vectornav.launch file to:

After running the commands:
sudo chmod a+rw /dev/ttyUSB0
and
roscore
and after that
roslaunch vectornav vectornav.launch

Using rostopic list
I can see the following topics:
~/catkin_ws$ rostopic list
/rosout
/rosout_agg
/vectornav/GPS
/vectornav/IMU
/vectornav/INS
/vectornav/Mag
/vectornav/Odom
/vectornav/Pres
/vectornav/Temp

and most of them works and shows me the messages:
IMU for example:

or temperature:

But the only one I need, with pitch, roll and yaw information, as I understand, should be in /vectornav/INS
and when I run the command:
rostopic echo /vectornav/INS
it just give me nothing:

Please, advise, what can be the issue here?

Thanks in advance!

Best,
Andrey
