Hi, Abhijit
We get enabled Wi-Fi Direct on Android 4.2, Pandaboard.
Abstract
working fine: AOSP + OMAP4AJ.2.4(wi-fi lib, supplicant) + OMAP4AJ.2.2(wi-fi drv)
combination is so important
working so-so: AOSP + OMAP4AJ.2.4(wi-fi lib, supplicant) + OMAP4AJ.2.4(wi-fi drv)
p2p scan OK, p2p connect NG

AOSP 4.2.1 - https://android.googlesource.com/platform/manifest -b android-4.2.1_r1

this guide may be not correct,
i want to additional confirm someone, ^_^
;;; Wi-Fi Direct is OK. next, I want to get Miracast on Android 4.2, Panda;;;
