ESP8266: Configure as a Station / Client
The ESP8266 Wi-Fi module can function as a Station / Client which allows other Access Points (APs) to connect to it. Station (STA) mode is useful when the module will only send / push data to another device as opposed to receiving / serving data. Prior to setting up the module as a Station, wire & configure ESP8266 module. It is also possible to configure ESP8266 module as an Access Point or both AP and STA modes simultaneously.
