Callback is crashing my main node #12

Closed ghost closed 5 years ago

ghost commented 5 years ago

I'm using two LDMRS sensors on my project, so I launched two nodes, each one with the right ip address. I launch them, ok, works. If I launch rqt, I cannot read the objects data. It shows me something like "not possible to reach sick_ldmrs_msgs/ObjectArray.h", even so, if I call the topics on my main node, I receive all incoming data from both sensors.

And then, suddenly this main node dies "process has die [pid... something]" but not the lidar's nodes. If I launch rqt again now, I can read all incoming data from both sensors.

It seems that when rqt accesses the sick_ldmrs_msgs/ObjectArray.h it crashes my main node.

Did it hapen to someone?

We only have one LD-MRS, so I cannot test this. It would be helpful if you could write the exact error message, and which commands you were running.

Hi @luhbartels, I am also working with two sick LDMRS lidars but have no idea how to modify the launch file to be able to connect to two lidars simultaneously.can you help by sharing a sample copy of the launch file. Thanks in advance
