This is an issue tracker, meant for tracking issues in our core code. It is not a general support forum. I suggest seeking help at esp8266.com or stackoverflow for basic questions. The LED connected to gpio2 is inverted on esp12 modules, so pulling the pin low makes it light up. That is normal. Closing.
