Re: [sumo-user] two clients, one SUMO connection (python - TraCI)

okey, still not working, here are my to client-snippets:

client1:

# default port
PORT = 8813

client2 = Com()


class runner:

    port = getFreeSocketPort()
    # if getFreeSocketPort returns None, initialize with default value
    if not port:
        port = PORT
    sumoBinary = "sumo-gui.exe"

    # starting sumo
    traci.start(cmd=[sumoBinary, "-c", "pathToConfig\\SUMO\\config.sumo.cfg", "--num-clients", "2"], port=8813)
    # establishing client order
    traci.setOrder(1)

client2:

# default port
PORT = 8813

class Com:

    def traci_client2(self):

        port = getFreeSocketPort()
        # if getFreeSocketPort returns None, initialize with default value
        if not port:
            port = PORT

        traci.init(port=8813, label="sim2")
        conn2 = traci.getConnection("sim2")
        conn2.setOrder(2)

        while traci.simulation.getMinExpectedNumber() > 0:

            traci.simulationStep()

so, as far as i understand, it stucks while it loads because sumo is waiting for client2?

Maybe you can see anything in my code.

Thanks and greetings

When the sumo gui has been started, it is waiting for the second client to connect. Note that you have to call setOrder for all clients and to call simulationStep for each client to proceed with the simulation

e.g. for the second client:

traci.init(port=xxxx, label="sim2")

conn2 = traci.getConnection("sim2")

conn2.setOrder(2)

step = 0

while step < 1000:

conn2.simulationStep()

step += 1

conn2.close()

thanks for the information Jakob!

So I implemented it, but when I start my runner script, it opens my sumo-gui as usually, but it's only displaying "starting server on port xxxx" and nothing happens, just loading. When I'm changing the --num-clients in the traci.start to "1" it starts normally.

Any ideas?

Greetings

Hello everyone,

so i'm new to SUMO and want to connect two different clients (both python scripts, Interface: TraCI) to the same SUMO connection.

How can I do that exactly? I read about the simulationSteps from the post yesterday, but I can't manage to implement it.

Thanks a lot.

Greetings!
