2920-24G PoE + with RYU controller

Hello, 

I am using the HP switch 2920-24G PoE + in Openflow 1.3 mode with a RYU controller.  I am trying to get a basic topology. I have created 2 VLANS, one vlan for the controller and another for the hosts.

I am trying to run Ryu controller's example simple_switch_13.py.  
 
I have worked with RYU controller with other switches, even with mininet and it works perfectly. However with the HP switch 2920-24G PoE switch, it does not work, no message is observed in the RYU controller.  I observe in the switch the controller connection UP, however, the RYU controller does not receive any messege. Could someone help me figure out what the problem is?. Thank you in advance for any information.

 

The running configuration is as follows:

hostname "HP-2920-24G-PoEP"
module 1 type j9727a
snmp-server community "public" unrestricted
openflow
   controller-id 1 ip 169.254.253.80 controller-interface vlan 1
   instance "of1"
      member vlan 2
      controller-id 1
      version 1.3 only
      enable
      exit
   enable
   exit
oobm
   no ip address
   exit
vlan 1
   name "DEFAULT_VLAN"
   no untagged 13-24
   untagged 1-12
   ip address 169.254.253.82 255.255.255.0
   exit
vlan 2
   name "VLAN2"
   untagged 13-24
   ip address 169.254.126.160 255.255.255.0
   exit
 
The openflow instance information is:
