Using AT commands
Every AT command starts with the letters AT. Here's an example:
AT+GMR <CR>
Type the AT command AT+GMR and press the Enter key. Don't type <CR>. The CR indicates carriage return.
This will return the firmware version ID of the ESP8266 module, as shown in Figure 1.8:

Likewise, you can run any AT command with the PuTTY terminal to execute on ESP8266 through the serial connection.
