# find_node_by_name.py - Find a node by "name" on the network.
# Robot Raconteur nodes can be identified by a "node name" or a "node ID". The node
# name is a human readable name that may or may not be unique. The Node ID is a 128 bit
# uuid that is statistically expected to be unique. This example shows how to find a node
# by its node name.
# The node name to find
node_name = "experimental.reynard_the_robot"
# Transports to search, in this case TCP and local
transports = ["rr+tcp", "rr+local"]
from RobotRaconteur.Client import *
import time
# After initializing the node, wait a few seconds for discovery to initialize
time.sleep(6)
ret = RRN.FindNodeByName(node_name, transports)
for s in ret:
print("NodeID: " + str(s.NodeID))
print("NodeName: " + s.NodeName)
# The connection URL returned is a normal Robot Raconteur connection URL
# without the "service" parameter. Multiple URLs may be returned
# if there are multiple paths to the node
print("ConnectionURL: " + str(s.ConnectionURL))
# Use the URL to connect to a service on the node
url2 = [u + "&service=reynard" for u in ret[0].ConnectionURL]
c = RRN.ConnectService(url2)
c.say("Hello from find_node_by_name!")
