I just get an ESP8266-01 WiFi module, and uploaded the example sketch Blink through Arduino IDE, but it's not work at all. The LED isn't blinking on GPIO2. Please help me to solve my problem. Thanks.

How did you connect the LED on GPIO2 ?
Are you connecting it in sink mode, otherwise, if connected in source mode, ESP will be in the wrong boot mode.

Hi! I tried to connect the LED in sink mode, but it didn't result anything. When powering the module the LED blinked one for a short time, but nothing else. Please help me!

Thanks.
