代码示例

1.点亮板载LED(GPIO16)

int led 16;
void setup(){
    pinMode(led,OUTPUT);
}

void loop(){
    digitalWrite(led,LOW);
}

2.设置WiFi(STA+AP模式)

#include<ESP8266WiFi.h>
//AP Config
IPAddress APIP(192,168,10,1);
IPAddress APGATE(192,168,10,1);
IPAddress APMASK(225,225,225,0);
//STA Config
IPAddress STAIP(192,168,2,220);
IPAddress STAGATE(192,168,2,1);
IPAddress STAMASK(225,225,225,0);
//HostName
String hname ="ESP_Demo";

void setup() {
  //Setup COM
  Serial.begin(115200);
  Serial.println();
  Serial.println("Boot!");

  //Setup WiFiMode
  WiFi.mode(WIFI_AP_STA);
  Serial.print("Wifi Initing!Please wait...");
  Serial.println();

  //WiFi
  WiFi.begin("GCLD","501501501");
  WiFi.config(STAIP,STAGATE,STAMASK);

  //AP
  WiFi.softAPConfig(APIP,APGATE,APMASK);
  WiFi.softAP("ESP_Test","01020304");

  //Setup HostName
  WiFi.hostname(hname);
  
  //Print WiFi Config
  delay(5000);
  Serial.print("WifiStatusCode:");
  Serial.println(WiFi.status());
  Serial.print("STAIP:");
  Serial.println(WiFi.localIP());
  Serial.print("APIP:");
  Serial.println(WiFi.softAPIP());
}

void loop() {
  
}
