ESP826601SWeb服务器成功启动：详细解决方案与实践指南

之前买的模块中&＃xff0c; 突然想到有这个模块。 一直未使用&＃xff0c;索性在疫情期间 研究使用一下。

现在代码如下

/*This sketch demonstrates how to set up a simple HTTP-like server.The server will set a GPIO pin depending on the requesthttp://server_ip/gpio/0 will set the GPIO2 low,http://server_ip/gpio/1 will set the GPIO2 highserver_ip is the IP address of the ESP8266 module, will beprinted to Serial when the module is connected.
*/#include const char* ssid &＃61; "************"; // wifi 2.4 名称
const char* password &＃61; "***********"; // wifi 2.4 密码// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);void setup() {// 初始化串口&＃xff0c;只是显示一些打印的状态消息Serial.begin(115200);delay(10);// prepare GPIO2// 控制片上led灯的引脚pinMode(2, OUTPUT);digitalWrite(2, 0);// Connect to WiFi networkSerial.println();Serial.println();Serial.print("Connecting to ");Serial.println(ssid);// 1.设置wifi模式为终端WiFi.mode(WIFI_STA);// 2.连接wifiWiFi.begin(ssid, password);
// WiFi.softAP(ssid, password); // 开AP热点// 显示连接状态while (WiFi.status() !&＃61; WL_CONNECTED) {delay(500);Serial.print(".");}Serial.println("");Serial.println("WiFi connected");// Start the server// 3.启动服务server.begin();Serial.println("Server started");// Print the IP addressSerial.println(WiFi.localIP());
