Hello everyone.
I didn't find my answer anywhere so that's why I am posting my doubt here, If I'm duplication the thread then pardon me.
I am using ESP8266 ESP-12E. I have updated LED blinking code successfully using Arduino IDE 1.6.8. The sketch was working on ESP-12E board. Then I have tried ESP8266 WEBSERVER Example. I've uploaded the code successfully to ESP12E. After ESP12E reset i connect GPIO to VCC. I'm getting only garbage over terminal. Baud rate is 115200. I'm using LM1117 to power up ESP8266, and Using Prolific USB-RS232. ESP12E was working great with AT command with same power supply and USB-RS232 converter. I have connected GPIO0, RST and CH_PD to VCC with 10K pull UP.
I'm using this CODE:

* This sketch demonstrates how to set up a simple HTTP-like server.
* The server will set a GPIO pin depending on the request
* http://server_ip/gpio/0 will set the GPIO2 low,
* http://server_ip/gpio/1 will set the GPIO2 high
* server_ip is the IP address of the ESP8266 module, will be
