The setup procedure is documented on http://www.espruino.com/WiFi - I'm afraid the boards that I'm selling right now don't have the 'getting started' card (just the web address on the PCB). I will add one, but I'm a bit busy getting Puck.js out there at the moment so intentionally haven't been pushing EspruinoWifi very much.
I'm pretty sure your problem is that you're reading analog values from A2 and A3, which the ESP8266 is connected to (so it'll put those pins into analog input mode, which will then cause the ESP8266 to become unresponsive).
If you remove
analogRead(A2)andanalogRead(A3)it should work fine - I just tested and it works here.
