Betreff: Re: [sumo-user] sumo multi-client feature
Hello,
All clients must call simulationStep on their own connection to let the
simulation advance.
Note, that traci.start() does not return a connection object but you can
retrieve it using traci.getConnection().
regards,
Jakob

Dear developers,
I am trying to connect multiple traci clients to sumo. Is this feature fully
supported in the current release 1.1.0?
In a last step we want to combine the c++ traci client and another python
client. We have tested both, 2 python clients, 2 c++ clients, and combinations.
None of them are working in our setup so far.
We are using the following workflow, however are not able to control sumo
simulation steps or access the subscription when using more than one client:
1. Set “num-clients 2” option in the config file (we also tried the
command line option)
2. sumoCmd = ["sumo", "-c", cfg]
connection1 = traci.start(sumoCmd, port=8813)
traci.setOrder(1)
connection2 = traci. connect(port=8813, numRetries=10, host="localhost")
connection2.setOrder(2)
step = 0
while step < 1000:
traci.simulationStep()
step+=1
Is there anything else to do?
Mit freundlichen Grüßen
