this thing is a piece of crap. I happen to be able to get it working with WifiESP connectWPA example. but when I upload the exact same sketch it stops working. or If I turn the device off and then on again, it stops working. It's unreliable and a big pain in the neck. Edit: I got my money back with no problems. So I'm slightly increasing the star rating for a hassle-free refund.
