unsupported_version_or_bad_message from Ryu controller

[bruce-szg]

Hi,

I have two raspberry pi devices: one for installing linc-switch and another for installing Ryu controller. After I successfully installed all packages for both devices, I try to connect Ryu controller using linc-switch by this “rel/linc/bin/linc console”.
However, it failed. It seems that Ryu controller can’t support the version of ofp message. The error information is as follows: “09:13:13.393 [info] Connection to controller 192.168.10.107:6633/0 closed because of {unsupported_version,5}”.
It makes me confused for a long time. Do you have met the similar problem? Could you give some support? Thanks a lot.
