There are mainly two types of event in Ryu:created form OpenFlow packets and
created from network states. For instance, EventOFPSwitchFeatures is generated
from OFPSwitchFeatures, while the EventOFPStateChange is generated from a
trigger of network state changed. You can find some information in
I think you should attach some pictures or text to show the error information.

attribute 'bytearray_to_hex'
but I still can find the bytearray_to_hex method in utils.py
Why?

Hi, all.
If I want to get some data from other module of app, what should I do?
I know we can use CONTEXT to get the app as a service, and then we can get
the data in that app. But, the logic of these two app is not about producer and
