Ya, 4.2 and later devices seem to have Wifi Direct working much better. Still, most of the apps out there dont take advantage of the 4.2-4.3 connection/permissions improvements. If you read the fine print, most apps don't actually use Wifi Direct. They just fall back to using Bluetooth or a common Wifi network when Wifi Direct craps out. The only app that I have seen that has managed to implement stable file transfer purely using Wifi Direct is HitcherNet, but it only works for 4.1 and higher.
Hey all. So wifi direct has always been kinda crappy and inconsistent since android rolled it out. but apparently some apps use it for comm's...anyone had success with these? If so, which ones? I saw superbeam, but i'm anti-qr code, so no dice. thx
