[sumo-user] 'Extended retrieval messages' info subscription

[Marcelo Andrade Rodrigues D Almeida <md@xxxxxxxxx>]

Hi everyone

How can I subscribe to retrieve 'Extended retrieval messages' information (e.g. vehicle leader and secureGap)

Everytime I include these I receive the following error message

[...]

#"VAR_LEADER",
#"VAR_SECURE_GAP",

[...]

"Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/share/sumo/tools/traci/domain.py", line 208, in subscribe
    self._connection._subscribe(self._subscribeID, begin, end, objectID, varIDs)
  File "/usr/share/sumo/tools/traci/connection.py", line 231, in _subscribe
    result = self._sendCmd(cmdID, (begin, end), objID, format, *args)
  File "/usr/share/sumo/tools/traci/connection.py", line 178, in _sendCmd
    return self._sendExact()
  File "/usr/share/sumo/tools/traci/connection.py", line 83, in _sendExact
    self._socket.send(length + self._string)
AttributeError: 'Connection' object has no attribute '_socket'

"

Thank you in advance

Sincerely,
