I haven't even figured out what type of network packets it is yet. I didn't see any TCP or UDP going by on my packet captures... All I saw was the ARP discovery so far.
Adrian, I had a similar problem until I switched to a (really old) network hub I had laying around. I'm not sure how you were trying to capture the packet data, I've always done this via ethernet and not with wireless.
I didn't get too far into this yet, I've just been grabbing packets and resending them using a pc to repeat commands sent from the App.
