![]() ![]() This is helpful when the username (SSID) and password of the WiFi network is unknown. The ESP Module is first setup as Soft AP mode before configuring it in Station Mode. ![]() Usually, an access point can provide internet through a wired network to its stations but as there is no wired interface, this Access Point mode is called Soft Access Point. In this mode, the ESP8266 Module acts as an access point and provide WiFi Network to other stations (like mobile or laptop). The second mode of operation is Access Point (AP) Mode. In Station Mode (STA), the ESP8266 WiFi Module will be connected to a WiFi Network that is already setup by an Access Point, like a WiFi Router. There are three modes of WiFi Operation in the ESP8266 WiFi Module. So, in order to use the ESP8266 WiFi Module in our Internet related projects, we need to first connect ESP8266 to WiFi and then access it from the internet.īefore going into the details of how to connect ESP8266 to WiFi, you need to understand the WiFi modes of operation of the ESP8266 Module. The ESP8266 WiFi Module can be interfaced to any other microcontroller (like Arduino or 8051) through UART and with the help of AT Commands, the Microcontroller can control the ESP8266 (connect to WiFi, update Firmware, etc.). ![]() The tiny ESP8266 (ESP-01) WiFi Module is making wonders in the DIY Community as it allows devices like Arduino to access Web Pages by connecting to the Internet. Alternative Way to Connect Your ESP8266 WiFi Module to a WiFi Network.How to Connect ESP8266 to WiFi Network using AT Commands?.There are many important things like Pin Configuration of ESP8266 (ESP-01) Module, How to connect ESP8266 to Arduino, and so forth that you must have a prior knowledge on before proceeding to connect ESP8266 to WiFi.Before proceeding, I strongly recommend you to refer to two of the earlier projects on ESP8266 WiFi Module: GETTING STARTED WITH ESP8266 AND ARDUINO and HOW TO UPDATE/FLASH ESP8266 FIRMWARE.So, without further ado, let me show you how to connect ESP8266 to WiFi and use it in our IoT (Internet of Things) and other WiFi based Projects. One thing (and it is an important thing) that I have missed (not intentionally) is to show you How to connect ESP8266 to WiFi Network. I have also shown you how to install firmware (AT Commands Firmware) onto the on-board ROM of the ESP8266 WiFi Module. In the previous ESP8266 Projects, I have given a brief introduction to ESP8266 WiFi Module, how to get started with ESP8266 and Arduino, what is the pin configuration of the ESP8266 ESP-01 Module and how to program the ESP8266 using Arduino as USB-to-Serial Interface. ![]()
