Why the joy node cannot work well using launch file while it works well using ros2 run?
Hi, I use ROS2 humble for developing robot. I want to use a joystick for controlling the robot, but when I run the joy node using launch file:
ros2 launch joy joy-launch.py
It shows warning:
[joy_node-1] [WARN] [1691248053.043572221] [joy_node]: Could not get joystick with name '': Haptic: Unable to get device's features: Invalid argument
But when I use ros2 run:
ros2 run joy joy_node
The node works well:
[INFO] [1691228079.448547240] [joy_node]: Opened joystick: Logitech Gamepad F710. deadzone: 0.050000
So how to solve this problem? Thank you!
