ı have a vnh5019 motor driver.

I use "Firmware Commands " (on github page) and motors are working no problem.

But when I used publishing /cmd_vel commands like that nothing work.

$ roslaunch ros_arduino_python arduino.launch

$ rostopic pub -1 /cmd_vel geometry_msgs/Twist '{ angular: {z: 0.5} }'

what can ı do for this problem ? thank you for advices...

Can you update your question and include a listing of your arduino_params.yaml file? Note that by default, the arduino_params.yaml file included in the ros_arduino_bridge package has the base controller turned off (use_base_controller: False) and the PID parameters are commented out.
