ERRCODE_MSOPTIMEOUT about rslidar_sdk

[TZECHIN6]

For me its not a IP issue, I have check everything and message can be see in Wireshark. The problem is caused by my flooded switch, which I accidentally connected multiple velodyne lidar before, and they broadcast udp message which flooded the device somehow. Power off the switch and everythings just work fine.

I don't know what is the root cause, even I directly connect to the lidar with host still got this issue. Is is really caused by the flooded switch is hard to tell. but it works somehow.

I have the same problem, how did you solve it?

[TZECHIN6]

I face the same issue as well. How do you solve that?

[HaoQChen]

Could you record a pcap file to us?

[wangshichang-726]

maybe the IP issue

How did you get the UI to set the IP? I am having a difficult time finding the tools for RS Lidar.

[TZECHIN6]

For the web UI, just like working with velodyne, assuming you haven't set the IP of RS LiDAR before, make sure your PC is also in a same subnet, then enter the default IP in the browser, you will enter the webUI.

Unable to access UI.

[TZECHIN6]

What UI are you mentioning? Would you provide more information, otherwise others hard to help. Thanks

@arwinder-jaspal @TZECHIN6 , hope this might still be helpful for you guys.

My Environment: Ubuntu 20.04 with ROS2 Galactic

I was able to get the sensor readings after setting the Lidar's destination IP address (Under the Settings Tab) to my PC's IP address. The default destination is 192.168.1.102 . An alternative would be to set your PC's IP address to the sensor's default destination IP.

The robot settings can be access via any web browser, the Lidar's default IP address should be 192.168.1.200. As long as you set your PC's ethernet IP address within the same subnet (255.255.255.0), you should be able to access the 'settings' page when you enter the lidar's IP address in your web browser.

Has anyone solved this issue? I am on Ubuntu 22.04 with ROS 2 Humble.
With a 1sec interval I receive an error message: ERRCODE_MSOPTIMEOUT

Wireshark shows DIFOP and MSOP packages.

1. Make sure you can ping the LiDAR (same subnet)
2. Confirm the ROS2 driver config setting is right.
3. If nothing works, try connect it without switch.

[maxpolzin]

Thank you for your prompt response.

1. Pinging is no problem.
2. I added an image of the Ros driver settings. Am I missing sth. in the settings?
3. That's a bit tricky atm, because of our network setup.

@TZECHIN6 Thanks again for your response.

I connected the BPearl directly to our computer via an Ethernet dongle. The error remains the same.
I uploaded our configuration parameters here: #139

The configuration is basically a fresh clone of the repo with the only change being in the config file to RSBP (for BPearl) on a clean Ubuntu 22.04 installation. Wireshark indicates MSOP and DIFOP packages.

Do you have any ideas what could go wrong? Does our BPearl maybe have an incompatible firmware installed?

[maxpolzin]

I am able to capture packages with Wireshark into a pcap file and visualize them with the RSViewer GUI tool. Uploaded screenshots of our configuration are here: #139

Sorry for the duplicated issue. If they are related, feel free to close one.
