im testing the use of wifi direct services in the official "wifi direct service discovery" sample within the Android SDK API 16 and later.

I have an xperia u with Android 4.1.2 and a nexus 7 with official 4.4

If I try to connect (through wifi direct settings system menu) with xperia u through nexus 7 menu, it will never connect. Get stuck, and after popup dialog on xperia u, it never connects. If I do the same through xperia u, both devices connect fine without any problem.

Same problem at any wifi p2p demo. Because of this I saw the logcat of xperia u and found an interesting thing

Code:
wlan0: P2P: Driver is still in Listen state - wait for it to end before continuing
For some reason the xperia u wifi direct stuck and never leave of this state to conect with the other peer. Also happens with xperia u on 4.0.4

Any solution? it's a bug?

Can you try with your tablets/smartphones connect with your xperia u?

PD: I can't post it into dev forum yet.

EDIT: this is a portion of the logcat of the nexus 7 trying to connect with xperia u:
