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.

Is ESP8266 an IoT device?

The ESP8266 is a system on a chip (SOC) Wi-Fi microchip for Internet of Things (IoT) applications produced by Espressif Systems. Given its low cost, small size and adaptability with embedded devices, the ESP8266 is now used extensively across IoT devices.

What is ESP8266 Wi-Fi module?

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 Wi-Fi networking functions from another application processor.

How do you send commands to ESP8266?

Start by uploading blink sketch to your Arduino then connect it to your ESP8266 like this: TX-TX and RX-RX. Now open Serial Monitor and send AT command and see if it responds. If so then you can control it using your Arduino by wiring it back to TX-RX and RX-TX.

Does Arduino Uno have WiFi?

The Arduino Uno WiFi is an Arduino Uno with an integrated WiFi module. The board is based on the ATmega328P with an ESP8266WiFi Module integrated. The ESP8266WiFi Module is a self contained SoC with integrated TCP/IP protocol stack that can give access to your WiFi network (or the device can act as an access point).

Why ESP8266 is used?

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.

Do you need a WiFi module?

You only need a WiFi device (PCI-E or USB) if that is your only option to connect to the house router. There are some motherboard models with builtin WiFi. And you probably do not need a sound card.

How do I know if ESP8266 is working?

The AT commands can be sent to the ESP8266 module through the terminal emulator. In the Arduino IDE serial monitor I just type the command in the top input text and press enter on the keyboard. Out of curiosity I check the firmware version by sending the AT+GMR command (View Version Info). My module is running v 0.9.
