Hi. I found the solution. In this case, I need to use this declaration
"_EVENTS = [event_message.EventMessage]" in my classes.
Ex:
***APP 1
class ConnectionManager(app_manager.RyuApp):
OFP_VERSIONS = [ofproto_v1_3.OFP_VERSION]
_EVENTS = [event_message.EventMessage]
def __init__(self, *args, **kwargs):
super(ConnectionManager, self).__init__(*args, **kwargs)
***APP 2
class ManagerRole(app_manager.
RyuApp):
OFP_VERSIONS = [ofproto_v1_3.OFP_VERSION]
_EVENTS = [event_message.EventMessage]
def __init__(self, *args, **kwargs):
super(ManagerRole, self).__init__(*args, **kwargs)
Thanks.
