No data being published on topics

[ZainCDEI]

I am launching the driver with the correct sensor and host IP addresses and it appears to have launched correctly with a few warnings (attached terminals screenshot).

The topic names also appear in the rqt topic monitor but they don't publish any data. I also tried to call ros2 topic echo and ros2 topic hz on the /scan topic but did not receive any data.

I can see the pointcloud being published when I access it through the web interface.

As part of debugging I played around with completely random IP values in the launch file here and it printed out the exact same info in the terminal: Node Configured and running without any IP related errors or warnings

I think I have the same problem.
The topic list is being confirmed, But there is no response when topic echo.
I've been confused by this issue for weeks.

I ask for help my friend

I switched to using this driver for my multiscan device and also updated the firmware. To update the firmware you need to download the SOPAS Engineering tool for windows and upload the firmware file according to your device.

You can first try by switching the driver first and then update the firmware.

Sorry, the product I'm currently using is sick company nanoscan3.

I'm trying to communicate with ros2 using the sick_safetyscanners2 package.

still..The topic list is being confirmed, But there is no response when topic echo.
