Hello, sorry for the delay.
Yes, I, have tried. The problem is that the topology is a bit complex, so I'm
running the applications in the following way:
tc.cmdPrint("ryu-manager --verbose --observe-links --wsapi-host 192.168.100.1
--wsapi-port 8080 --ofp-listen-host=10.0.0.100 --ofp-tcp-listen-port=6653
../ryu/transport_operator.py ../ryu/ryu_view/ryu_view.py
ryu.app.transport_rest_topology ryu.app.ofctl_rest
ryu.app.transport_ws_topology ryu.app.rest_conf_switch &> /tmp/tc-out &")
tc.cmdPrint("ryu-manager --verbose --wsapi-host 192.168.100.1 --wsapi-port 8081
--ofp-listen-host=10.0.0.100 --ofp-tcp-listen-port=6654
ryu.app.almost_intelligent_switch_13 ryu.app.gui_topology.tenant_gui_topology
ryu.app.tenant_rest_topology ryu.app.ofctl_rest &> /tmp/t1-out &")
Those two lines are executed one after the other. Now, the problem is, how can
I send a event from one app executed in the first
command to another executed in the second one? I want to send the event from
transport_operator.py to tenant_rest_topology.
Thank you.
Felipe Rodriguez

Have you tried to send_event EventEntryPoint?
With the debug logging turned on, it should report if a event is
delivered or not.
