Whats a WiFi module?
The Wi-Fi module generally contains two main parts: a Wi-Fi chip and an application host processor. The Wi-Fi subsystem includes an 802.11 radio physical layer (PHY), baseband, media access control (MAC), and perhaps a crypto engine for fast, secure Internet connection.
What kind of device is the ESP8266 WiFi module?
7. What kind of device is the ESP8266 WiFi Module? Explanation: The ESP8266 WiFi Module is a networking device since it’s main function in any system is to be able to connect to any nearby WiFi network for uploading or downloading data hence enabling IOT.
Does ESP8266 have its own WiFi?
The ESP8266 that creates its own WiFi network and acts as a hub (Just like WiFi router) for one or more stations is called Access Point (AP). Unlike WiFi router, it does not have interface to a wired network. In AP mode ESP8266 creates a new WiFi network and sets SSID (Name of the network) and IP address to it.
What is ESP8266 used for?
The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all WiFi networking functions from another application processor.
What does an ESP8266 do?
The ESP8266 module enables microcontrollers to connect to 2.4 GHz Wi-Fi, using IEEE 802.11 bgn. It can be used with ESP-AT firmware to provide Wi-Fi connectivity to external host MCUs, or it can be used as a self-sufficient MCU by running an RTOS-based SDK.
How do I connect an ESP8266 to WiFi?
To see if it works, open the Wi-Fi settings on your computer, look for a network called “ESP8266 Access Point”, enter the password “thereisnospoon”, and connect to it. Then open a terminal, and ping to 192.168. 4.1 (this is the default IP address of our ESP AP). You’ll see that the ESP responds to your pings.
How do I make ESP8266 WiFi?
esp8266-wifi-setup
- booting and read Wifi config from EEPROM.
- if Wifi config is not found, starting SoftAP at SSID “ESP8266_SETUP”.
- connect this Access point with your devices.
- Wifi Settings page will automatically open by Captive Portal.
- select the SSID, enter the password.

How does ESP8266 Wi-Fi module work?
In order to setup your Arduino IDE to work with your esp8266 arduino compatible module you need to make the following steps:
- Connect your ESP8266-01 Module to PC.
- Open your Arduino IDE.
- Go to File -> Preferences.
- Add this link to Additional Board Manager.
- Go to Tools -> Board Manager.
- Find ESP8266 board set and activate it.

Can ESP8266 replace Arduino?
When it comes to programmable PWM frequency, there is no doubt that Arduino will not be able to replace ESP8266 or ESP32 over the next few years or even decades. This is mainly because the ESP8266 has a built-in PWW frequency call.
