launch file ignoring a message
I'm using a launch file to start a driver node and another node at the same time. Meanwhile, I'm running another file, which is supposed to publish a message to a topic, to which the non-driver node in the launch file is subscribed. When I don't use the launch file and run the driver separately, everything works fine. The message is published and read correctly. However, when I use the launch file, the message appears not to be read.
