ps3 controller lag

edit

Hello everyone, I am writing some code to do some basic bluetooth teleop control of a robot, and for some reason when I try to move forward for an extended period of time it does cuts out until the controller is updated. is this a timeout problem? If so how could I change the timeout?

#!/usr/bin/env python

# Simple Joystick Control Node
#  

import rospy
from geometry_msgs.msg  import Twist
from sensor_msgs.msg    import Joy
from actionlib_msgs.msg import GoalID

def joyCB(msg):
  rospy.logdebug("Joy Recieved: [Vx:%f, Wz:%f]"%(msg.axes[linear_axis], 
                                                 msg.axes[rotation_axis]))

  cmd_vel_msg = Twist()
  cmd_vel_msg.linear.x  = msg.axes[linear_axis]   * linear_scale  
  cmd_vel_msg.angular.z = msg.axes[rotation_axis] * rotation_scale
  cmd_vel_pub.publish(cmd_vel_msg)

  # PS3 Triangle Button (12) - abort navigation command
  if msg.buttons[12]:
    nav_abort_pub = rospy.Publisher("/Pioneer3AT/move_base/cancel", GoalID)
    abort_msg = GoalID()
    #abort_msg.stamp = rospy.Time.now()
    #abort_msg.id = ""
    nav_abort_pub.publish(abort_msg)


if __name__ == '__main__':
  rospy.init_node('teleop_joy')

  global cmd_vel_pub
  global linear_axis
  global linear_scale
  global rotation_axis
  global rotation_scale

  linear_axis    = rospy.get_param('linear_axis'   , 1)
  linear_scale   = rospy.get_param('linear_scale'  , 1.0)
  rotation_axis  = rospy.get_param('rotation_axis' , 2)
  rotation_scale = rospy.get_param('rotation_scale', 1.5)

  cmd_vel_pub = rospy.Publisher("cmd_vel", Twist)

  rospy.Subscriber("joy", Joy, joyCB)
  rospy.spin()
