How do you give a name to a rosserial_arduino node? There are several good examples, but none of them specify a name, resulting in the published topics and listeners appearing in the root namespace.
Normally, a node's name is specified with ros::init(argc, argv, "some_name"); but it doesn't look like rosserial_arduino supports this.
you can chage the node name with an ros Lauch file
here my code in my Launch file:
<node pkg="rosserial_python" type="serial_node.py" name="serial_stepper_node">
<param name="port" value="/dev/ttyUSB0"/>
</node>
Another way:
cd /opt/ros/noetic/lib/rosserial_python
sudo cp serial_node.py [new_node_name].py
sudo nano [new_node_name].py
scroll to line containing: rospy.init_node("serial_node") and replace "serial_node" with "[new_node_name]"
sudo chmod +x [new_node_name].py
rosrun rosserial_python [new_node_name].py /dev/ttyUSB0
IIRC, rosserial will always publish using global names.
I've seen people push the rosserial node(s) into a namespace to change that.
