you can check on the switch side (mininet) to see if the switches are connected to the controller:

sudo ovs-vsctl show

you can check the operational side of OpenDaylight to see if the switches are learned:

http://<controller ip>:8181/restconf/operational/opendaylight-inventory:nodes/

If the switches aren't connected or learned, my next step would be to do a packet capture on the mininet system for port 6633 and see if there are any clues there? you can get a packet capture with something like:

sudo tcpdump -ni eth0 port 6633 -w <filename>

good luck.
