Hi,
Actually, I have a problem with Ryu and OF 1.5 as well, even though I have the
latest version of OVS which is 2.4. But it is different.
I am trying to connect OVS switch working in OpenFlow 1.5 with Ryu, but I
couldn’t.
I have got this error:
loading app ryu.controller.ofp_handler
instantiating app /home/ubuntu/Desktop/2h-rc.py of My_Ryu
instantiating app ryu.controller.ofp_handler of OFPHandler

I tried that with OpenFlow 1.4 and earlier and it works.
Could you possibly tell me how can I fix this problem?
Thanks
Anees

Which switch are you using?
The above messages shows no available version in the Hello message which sent
from your switch.
By this setting(OFP_VERSIONS = [ofproto_v1_5.OFP_VERSION]), Ryu sends the Hello
message with:
OF1.0 X
...
OF1.4 X
OF1.5 Supported <--
But, your switch may send with:
OF1.0 ?
...
OF1.4 ?
OF1.5 X Not supported <--
Please confirm your switch supports OpenFlow1.5.
