Hmm, strange. Could you please edit the launch file and set the parameter publish_datagram to true (you also have to move that line so it's not commented out):

sick_tim/launch/sick_tim571_2050101.launch

Line 15 in 40784b5

<param name="publish_datagram" type="bool" value="False" />

Then record a short rosbag of the "datagram" topic and attach it here.

rosbag record --lz4 -l 300 /datagram

Your scanner has the device string set to the empty string. By default, it is set to the string "not defined". There was a bug in the parser that caused this issue. I have just pushed a commit that fixes the problem. To use it, you'll have to pull the latest code and build from source.

Thanks for your bug report!

You should pull the latest code and compile it from source. Your log output shows that you are still running the old code.
