So I saw @Luciffer do this at his home. There was a QR code and if you scan it, boom you are connected to wifi. I downloaded a qrcode app on android, put wifi password and SSID and created a QR code. However when I scan it back it doesn't connect to wifi, it does however obtains the information about wifi. It pointed out downloading and installing another qrcode plugin for wifi, which is already installed but it was not helping in anyway. Also I heard that iphone won't allow to connect anyway directly? Help/Advice?
