Hi all,

We have the SDN network implemented using
switch models: TP-Link TL-WR1043ND
Firmware: OpenWRT 10.03 (backfire)
OpenFlow: 1.3 from
https://github.com/CPqD/ofsoftswitch13/wiki/OpenFlow-1.3-for-OpenWRTand
the NOX cotroller from https://github.com/CPqD/nox13oflib
When I start the NOX controller, I get following error..

admins at sdn-ctl1:~/nox13oflib/build/src$ ./nox_core -i ptcp:6633

NOX 0.9.0(zaku)~full~beta (nox_core), compiled Nov 19 2013 14:09:43
Compiled with OpenFlow 0x04
00001|openflow|WARN:stream: version negotiation failed: we support versions
0x04 to 0x04 inclusive but peer supports no later than version 0x01
00002|nox|WARN:Error sending features request: Protocol error
