Not able to ping OS-2

Martin_Aa_S

Hi!

I am struggling with connecting with the OS-2 lidar.
If I run:

avahi-browse -arlt

I am able to find the LiDAR at:

= enp5s0 IPv6 Ouster Sensor 992209000923 _roger._tcp local hostname = [os-992209000923.local] address = [fe80::be0f:a7ff:fe00:52e0] port = [7501] txt = ["fw=ousteros-image-prod-aries-v2.4.0+20220921174636" "sn=992209000923" "pn=840-103576-06"] = enp5s0 IPv4 Ouster Sensor 992209000923 _roger._tcp local hostname = [os-992209000923.local] address = [192.168.1.99] port = [7501] txt = ["fw=ousteros-image-prod-aries-v2.4.0+20220921174636" "sn=992209000923" "pn=840-103576-06"]
However, if I try to ping the unit I get no response. I have tried both the following:
ping os-992209000923.local
ping 192.168.1.99

This is in contrast to what the Software User Manual says:
"On most systems you should be able to connect the sensor into your network or directly to a host
machine and simply use the sensor hostname to communicate with it."

My own IP address is the following:
"inet 192.168.100.183 netmask 255.255.254.0 broadcast 192.168.101.255"

I am using DHCP and need to do so because I have other sensors connected this way.

I am not able to run the SDK either, because it does not find the OS-2. What might be the issue here?
Thank you

Hi @Martin_Aa_S

I’d recommend first to try reset the lidar’s configuration from the lidar’s webpage, to make sure the lidar is in dhcp configuration and not fixed IP.
Make sure your DHCP server is running fine on your PC.
The general idea is that the sensor and computer need to be configured in the same subnet to communicate. (ex: PC IP: 192.168.3.100, LIDAR IP: 192.168.3.104, Netmask: 255.255.255.0)
Are you using some switch in between to connect to the lidar? If yes, try to connect the lidar on another port, then ping the lidar again to check if one of the switch’s ports is defective
I’ve seen your dhcp configuration is the following:
inet 192.168.100.183 netmask 255.255.254.0 broadcast 192.168.101.255
May I ask you, how many sensors are you using? As a quick test, Is it possible for you to set 255.255.255.0 as network mask and configure your PC with inet 192.168.100.183 netmask 255.255.254.0 broadcast 192.168.101.255
A quick test I’d try is to set up the netmask
I’d be happy to set up a call with the customer.

Best,
Mohit
