Step 4: Open your Arduino IDE, make sure you are connected to the FTDI COM port (mine is COM20). Mine is connected to COM20 as shown below. Step 3: Connect the FTDI board to your computer and open Device Manager, under COM ports you should see to which COM port your FTDI module is connected to, note it down. If you made the connections as explained in previous tutorial your board should look something like this And have used Push button to reset the ESP. We have used jumper switch, in board, to select between programming through AT command and through Arduino IDE.

Make sure the GPIO0 pin is left free and the RST pin is connected to ground momentarily and then left free. Step 2: Connect your ESP module and the FTDI module to the development board and power it ON. This tutorial uses Arduino Serial Monitor since most of us have experience by using it with Arduino boards.

Step 1: Install any Serial monitor software. The circuit diagram again is shown here for reference: This is very well explained in the previous tutorial. Then the most important step is wiring your ESP module properly.

  • Must have read the Previous tutorial and the above connection should be made.
  • #Software serial esp8266 at commands software

  • Any Serial monitor software like putty or even Arduino will work.
  • You would need the following for this project: So let’s get started…Īlso check our various ESP8266 based interesting IoT Projects. To enable this connection this Rx and Tx pin of the ESP module is connected to the Tx and RX pin of FTDI module respectively as explained in the previous tutorial. These AT commands can be sent directly from any Serial monitor software (Putty or Arduino) from our computer, basically in order to send these AT commands a Serial communication has to be established between the ESP modules and the Computer. But, for the purpose of this tutorial I am using only few commands just to check the firmware version of the module and set the module to work in AP (Access Point) mode. You can read through documentation to understand what each and every command will do. The complete list of AT commands which can be used to control and program the ESP8266 is given in documentation by Espressif Systems. An AT command always starts with the letter AT and is followed by some specific command. AT commands are the instructions which can be used to control a specific modem, in our case it is the ESP8266 module.

    The first and the easiest way to program your ESP module is by using the AT commands. Programming the ESP8266 using AT commands:
