def actionlib.action_client.ActionClient.wait_for_action_server_to_start (   self,
  timeout = rospy.Duration(0.0) 
)

[Deprecated] Use wait_for_server

Definition at line 565 of file action_client.py.

def actionlib.action_client.ActionClient.wait_for_server (   self,
  timeout = rospy.Duration(0.0) 
)

Waits for the ActionServer to connect to this client.

Often, it can take a second for the action server & client to negotiate a connection, thus, risking the first few goals to be dropped. This call lets the user wait until the network connection to the server is negotiated
