Click the Open button, and a Pu TTY terminal session window should open.Enable Caps Lock on your PC, and type AT, but don't press Enter. If you don't, you may have selected the wrong COM port or the wrong baud rate.Somewhere there is a document that defines the commands that are included in version 0.25.0.0, but without that document you must use trial and error to determine the AT commands that work.
This is the author's second article about the ESP8266 integrated circuit, a relatively new chip comprising a full-featured 32-bit RISC µC and a built-in 802.11 b/g/n Wi-Fi circuit.The first article described using the Arduino IDE to program the ESP8266, and contains some important background information that will not be repeated here. There is no shortage of information on the Web about the 8266; in fact, there may be too much..the wrong type.When you see AT in the Pu TTY terminal window, while holding the Ctrl key down, press the M key followed by the J key. You should see OK in the Pu TTY terminal window as shown in the picture below.Note that if you make a typing mistake while in the terminal session window, it may not be possible to successfully correct the mistake.You can use another terminal program, but you will have to make allowances for any differences between it and Pu TTY. Enter the COM port number (which must be less than 10) and the baud rate (which will most likely be 115200 or 9600.) In the small Saved Sessions window, enter ESP8266, and click the Save button.
The Pu TTY window should be similar to the picture below.
Adding to the confusion is the existence of another forum that, despite being named esp8266.com, doesn't seem to be operated by Espressif.
In addition, there is a plethora of resellers, video bloggers, and writers that also offer information that runs the gamut from good to confusing to totally wrong.
This should place your previously determined COM port and baud rate settings in the appropriate windows.
Click the Open button, and a new Pu TTY terminal session window will open. When you see AT GMR in the Pu TTY terminal window, while holding the Ctrl key down, press the M key followed by the J key. You should see the ESP8266 firmware information in the Pu TTY terminal window similar to that shown in the picture below.
