Hello Maryam, There is one more thing I can think of as a source of error given the provided information, which is that the setOrder-command should be sent for each client *before* sending the first simulationStep-command.
If this does not fix the problem, I’d ask you to provide a more detailed description of what you did and what unexpected results you observe – at best a minimal failing script or example. Also keep in mind that the first thing you will read out of the inMsg (after the length) should be the 0x03 identifier-ubyte, which acknowledges the setOrder-command, not 0x00, which should be the second ubyte.

I checked the value of the inMsg, it doesn’t return 0x00, so according to your explanation, it means the execution of setOrder is not successful. and then when the simulationstep is going to run by the first client, the function 'check_resultState' fails and it just stuck and doesn’t go further in the simulationstep function. and I think because the setorder has not acknowledged successful , so simulationstep doesn’t work. do you have any suggestion for me ?

It returns an acknowledgement of the received command (the command id itself 0x03 in case of CMD_SETORDER) and a status-flag (0x00 indicates successful execution). So you should expect to receive the same response even if you call setOrder(n) with different values for n from various clients. See http://sumo.dlr.de/wiki/TraCI/Protocol for the general protocol specs. Hope this helps.

November 2017 22:30 An: sumo-u...@lists.sourceforge.net<mailto:sumo-u...@lists.sourceforge.net> Betreff: [sumo-user] problem with multiple clients of TraCI in sumo 0.31 Hi, As new version of SUMO (0.31) supports the multiple clients of TraCI, I have implemented it in c++ API. The problem is that the function of setOrder which is implemented in TraCIAPI.cpp , does not work correctly since if i set the input value of the function as 1 (setorder(1)), the value of message which is sent to the socket is nor 1 (outMsg =! 1 ), neither same as the value of message of checking function (check_resultState(inMsg) -> inMsg=! 1). it means the setting value for setOrder function does not depend on input value, both setOrder(1) and setOrder(2) send same message with same value to the socket ! so the value can not be set correctly, then simulation step won't work! It would be great if anybody can help.
