サンプルコード

#include <ESP8266WiFi.h>

const char * ssid = "001D736531AA_G";
const char * password = "";
WiFiServer server(80);
void setup() 
{
    Serial.begin(115200);
    delay(10);
    pinMode(2, OUTPUT);
    digitalWrite(2, 0);
    Serial.println();
    Serial.println();
    Serial.print("Connecting to ");
    Serial.println(ssid);
    WiFi.mode(WIFI_STA);
    WiFi.begin(ssid, password);
    while (WiFi.status() != WL_CONNECTED)
    {
        delay(500);
        Serial.print(".");
    }
    Serial.println("");
    Serial.println("WiFi connected");
    server.begin();
    Serial.println("Server started");
    Serial.println(WiFi.localIP());
}
void loop()
{
    WiFiClient client = server.available();
    if (!client)
    {
        return;
    }
    Serial.println("new client");
    while (!client.available())
    {
        delay(1);
    }
    String req = client.readStringUntil('\0');
    client.flush();
    String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<!DOCTYPE HTML>\r\n<html>";
    s += "<body><textarea rows=10 cols=80>";
    s += req;
    s += "</textarea></body></html>\r\n\r\n";
    client.print(s);
    delay(1);
    Serial.println("Client disonnected");
}

以上。
