Maybe you need to adjust your cmakelists.txt file.

Could you add a picture of the specs that you're using or even the web GUI with the values?

You can make a new thread in your Python program and have it call a function called callback that doesn't take inputs.

Yeah, not sure it would do what you want otherwise.

Mark as answered and close if it works.

If you want to connect it, then try. rospy.init_node('teleop_list', anonymous=True) rospy.Subscriber('key_vel', Twist,

I'm telling you how to do something when the subscriber isn't triggered. Plus, you can't call callback(data) without pro

That's perfect. Thank you.

Are there any sites with instructions on how to make a program that people can install from a ROS project? I haven't found any specifics so I'm not sure if it's the same as other projects.

It can also be done this way:

std_msgs::String msg;
msg.data = "hello";

Thanks for the help.

If you don't mind, could you write the answer out. I don't have enough points to accept my own answer yet. I'll accept yours and close it.

I checked the wired connection settings and it seems like it was set to Automatic (DHCP). It works now that I set it to manual and input the ip and mask. Thanks.

I'll give that a shot. I was having trouble before when I wasn't fiddling with the ip addr but I'll see if I can make it work with just a static IP.

I was following this answer.

I am on a wireless network. Do I need to turn off wifi while connected to the LIDAR?

When I connect the VLP-16, the connection works fine, but after a few minutes Ubuntu indicates that the connection has been disconnected.

These are the commands I input into the terminal to get a data feed.

sudo ifconfig eth0 up
sudo ip addr add 192.168.1.200 dev eth0 
sudo route add -net 192.168.1.0 netmask 255.255.255.0 dev eth0
roslaunch velodyne_pointcloud VLP16_points.launch  calibration:=/home/user/PUCK_Calibration.yaml

I need the connection to be stable between the laptop and the LIDAR for a very long time. Is there a stable way to establish a connection? Because when it disconnects, I need to rerun those commands to get data from the lidar again.

Am I doing something wrong?

I am using Ubuntu 14.04 LST with ROS Indigo.
