Heey sponder,
Are you able to get the desired output i.e turning on and off LED and writing on the LCD from this code?. Am asking this because I realized you are using Serial instead of spiSerial.
Also how do you clear the LCD every time you receive data from the wifly? I tried to put lcd.clear() after spiserial.available() statement but only the first letter of the newly received message is displayed.
Thanks.
