I've made MIDlet which use NFCIP-1 communication to exchange messages between two phones, quite similar which is in WIKI demos. Problem I have that communication between two phones are quite poor, its need a long time to make that message sent. Sometimes its failed at all, so I restart MIDlet.

I wonder, where is the problem?
Is anybody have same one?

I know where antenna located in the phone so its not the case.
