Hello guys,
Im trying to connect my Arduino Uno to Gazebo simulator via ROS to control a robot model.
I set up the installation of rosserial according to the tutorial and moved on to the hello world tutorial.
However when I want to connect my arduino Uno with:
`rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0` (Im sure I have the correct serial port)
I get the following message:
[INFO] [WallTime: 1414579866.487628] ROS Serial Python Node
[INFO] [WallTime: 1414579866.493390] Connecting to /dev/ttyACM0 at 57600 baud

self.pub_diagnostics = rospy.Publisher('/diagnostics', diagnostic_msgs.msg.DiagnosticArray)
[ERROR] [WallTime: 1414579883.599380] Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino
I already reinstalled rosserial, but that didn't help.
Anyone with an idea?
Thanks in advance!
