What is your firmware version? I had the same issue with firmware version 15.10.01.08 and updated to the latest version 15.10.01.15, that solved the issue for me.

I have encountered the same problem as you. Can you provide me with a specific solution? Thank you

[DerK96]

did you update your firmware to the latest version?

[stevencolinmartin]

Updated firmware also resolved this for me.

不好意思，刚看到你的邮件,我的问题已解决 ros主从机设置时网关为192.16.0.1，激光雷达的ip设置时网关也被设置成了192.168.0.1 切换网络后，ros主从机的网关更改，报错解决。 问题应该是ros主从机的网关与激光雷达冲突，更改其中一个即可

[reddittoob]

what does it mean switching the network?

I don't understand your solution. Please let me know about details.

I encountered this problem and I solved it in another way. I set my host IP to 192.168.1.50 but it doesn't work. Then I found that the manual said you also need to set the subnet mask to "255.255.255.0". Then it works.

My experience is that if

1. Init fail -> Either the Host & Lidar IP address is incorrect or the network settings is incorrect
2. Detection success but update lidar fail -> IP is correct but subtle errors such as subnet mask hinder the communication

[reddittoob]

I already set subnet mask to "255.255.255.0". But I still have same problem.
