Multi client SUMO scenario doesnt advance in time

[CiscoFrisco]

Hi once again,

I recently implemented an ambassador in my MOSAIC scenario to communicate with a python server. This python server connects itself to SUMO via a Traci Client. So far, after running my scenario, SUMO connects both the TraciClient implemented by MOSAIC and the one in the python server and loads the scenario. However, when I try to start the simulation nothing happens.

I know from the SUMO documentation that in multi-client scenarios, for the simulation to advance all of the connected clients must advance their timestep. Since MOSAIC already does so for the Traci Client it implements, I tried to the same by having the ambassador tell the python server to advance the timestep. The python server then just needs to call a sumo method to do so. However, I do not know what type of interaction or method MOSAIC uses to handle the time advance of SUMO. Ideally, I would use such interaction in my ambassador and do the above when processing it.

Any idea on what to use to have the simulation advance its time?

Best regards,
