I am following the official procedure to install a VLP-16. Despite going precisely through the guide my lidar is not showing any point on RViz

Below all the steps I followed:

Preliminary steps:

1 Make sure sudo apt-get install ros-melodic-velodyne is installed, which it is.

2 Check connection options using ip a

emanuele@pc:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp109s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 80:fa:5b:73:21:ec brd ff:ff:ff:ff:ff:ff
    inet brd scope global noprefixroute enp109s0
       valid_lft forever preferred_lft forever
    inet6 fe80::1b19:3020:d4bc:4bb5/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
3: wlp112s0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether a8:6d:aa:9b:43:e9 brd ff:ff:ff:ff:ff:ff

3 My ethernet connection is called enp109s0 and went ahead with that to the guide

1 Setting up your computer to communicate with the Velodyne VLP-16 sensor

1a) Power the LIDAR via the included adapter

1b) Connect the LIDAR to an Ethernet port on your computer.

1c) For now, disable the WiFi connection on your computer.

2 Configure your computer’s IP

Below the connection procedure: I created a velodyne_interface connection, see below:


Existing Connection




3 Connecting your computer to LIDAR through terminal

emanuele@pc:~$ sudo ifconfig enp109s0

Add a static route to the LIDAR's IP address.

emanuele@pc:~$ sudo route add enp109s0

4 Checking the configurations [Problem is here]

To check the connection open your web browser and access the following sensor’s network address.

The problem is that I never get to see the webpage showing the lidar data. Basically I never get to see the page below provided in the official documentation:


What I tried so far:

I wasn't totally sure about the correct address of the lidar and came across this source and applied all possible techniques:

1) I looked on the back of my lidar and found the following MAC address: 60-76-88-38-1C-4A

Now since, according to the post, the last four Hex digits map to the IP address of the device, I mapped 1C Hex = 28 and 4A Hex = 74

and replicated the following but it didn't work and still can't access to the webpage showing the parameters:

emanuele@pc:~$ sudo ifconfig enp109s0
emanuele@pc:~$ sudo route add enp109s0

2) I downloaded WireShark, connected the lidar via ethernet to it and below is a print screen of what I saw:




Of course ... (more)

It is not showing in rviz. Can you echo the topic?

@ct2034, thank you very much for reading the question. Which topic should I echo?

just updated the question with rostopic echo /velodyne_points but nothing is showing up

I am sorry but I am not familiar with the sensor I just wanted to make sure that it is not a rviz problem, because I thought it was, judging by the title.

Good point the question could be misleading. Thanks. I just updated it to make it more clear :)

I'm not sure if this helps. But in our lab we used to give netmask as 24. We also had problem wen we used 255.255.... don't know exactly what it does. But you can give it a try.

No, just 24
