[EN] WiFiServer
After studying the ESP8266WiFi to control the microcontroller connected to a wireless network in an STA and SoftAP form, then learned how to use the WiFiClient to use the esp8266 as a client node. This time, it’s about WiFiServer to make esp8266 act as a service node or Server. The example in this article is to create an internal network system by using 3 esp8266 to act as SoftAP, Server and Client as shown in Figure 1.
