When I connected my Wiznet812MJ to atmega64p, everything is fine using tcp protocol. However, when I use UDP protocol, it seems not working.
I used Wireshark to see what happens.
It always display
who has 192.168.1.2? Tell 192.168.1.6
192.168.1.2 is at a4:ba:db:95:3a:e8
who has 192.168.1.2? Tell 192.168.1.6
192.168.1.2 is at a4:ba:db:95:3a:e8
who has 192.168.1.2? Tell 192.168.1.6
192.168.1.2 is at a4:ba:db:95:3a:e8
who has 192.168.1.2? Tell 192.168.1.6
192.168.1.2 is at a4:ba:db:95:3a:e8
and so on....So the data cant send out.
Note: 192.168.1.2 is the destination (my laptop IP)
192.168.1.6 is the IP of the Wiznet/Atmega.
when I'm using TCP, no problem at all. I can ping all the times.
what's seems wrong?
