This tutorial shows how to connect the ESP WiFi module to a Serial adapter (FTDI), connect to an access point and perform an HTTP request. Page with AT comma. ESP8266 Arduino tutorial – WiFi module complete review. Technology goes ahead exponentially with each year whether we do something or not. With the same speed engineers work hard to reduce the size of every electronic device or component and loose most of the wiring. Now that we’ve connected the ESP8266 module to the Arduino, it’s time to send out special commands through the Arduino’s (software) serial port. This AT or Hayes commands are a set of commands not only used by the ESP8266 but also by other modems like GSM, Bluetooth and GPRS. The whole list of AT commands is overwhelming.
Data communication between electronic devices is inevitable in many electronic projects and brings a lot of advantages to your project i.e. connecting your microcontroller to PC and monitor data on a large colorful display instead of small monochrome LCD. When talking about connecting a device to PC, the most obvious way of communicating is USB port. But transmitting data over USB requires lots of programming. Another easy way is Serial Port (aka COM) and RS232 protocol that only needs a tiny electronic circuit to convert voltage levels and a little programming. So I made an RSS232-TTL UART adapter and published here to uses in all of my projects. But I faced a new problem, new motherboards and laptops have no COM port. Then I decided to make a USB-TTL UART adapter using famous FT232 IC for my projects. It works very well, but long wires from devices to PC are annoying me. Is it possible to have the serial port on the air like wireless mice and keyboards? Of course, it can be done using lovely WiFi module ESP8266, and by using WiFi you have not to make a dongle yourself and also you can have a serial port over the internet. Wow, I just wanted a wireless serial port, now I also have a serial port over the web. That's very exciting.
