Re: [sumo-user] problem with multiple clients of TraCI in sumo 0.31

Hello,

The response (inMsg) is not supposed to return the assigned order. 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.

Best,
Leo

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.

Thanks and best regards
