ESP8266 ESP 01
ESP 8266 ESP 01 is a Wi-Fi module that helps us to access Wi-Fi Network with any controllers. This module is a self-contained SOC with integrated TCP/IP protocol. This doesn’t need any controller to manipulate input and outputs whereas Raspberry Pi, Arduino, etc., requires. Based on the versions, the input and output pin varies. We can control anything around us using Wi-Fi with the help of this ESP module instead of wired controlling.
Each ESP8266 module comes pre-programmed with an AT command set firmware. The ESP8266 is capable of either hosting an application through Wi-Fi networking functions from another application processor. This module is an extremely cost-effective board with a huge, and ever-growing, community.
This module has a powerful enough onboard processing and storage capability that allows it integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existence interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions and requires no external RF parts.
Three Modes of ESP 8266 :
- Access Point(AP)
In AP the Wi-Fi module acts as a Wi-Fi network, or access point, allowing other devices to connect to it. It simply establishes a two-way communication between the ESP8266 and the device that connected to it via Wi-Fi.
In STA mode, the ESP-01 can connect to an AP such as the Wi-Fi network from your house. This allows any device connected to that network to communicate with the module.
The third mode of operation permits the module to act as both an AP and an STA.
