示例代码: 以下是一个使用Arduino Ethernet库发送GET请求的简单示例: 代码语言:txt 复制 #include <Ethernet.h> byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; IPAddress ip(192, 168, 1, 177); void setup() { Serial.begin(9600); Ethernet.begin(mac, ip); } void loop() { ...
password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting to WiFi..."); } Serial.println("Connected to WiFi"); } void loop() { IPAddress gatewayIP = WiFi.gatewayIP();
Serial.println("Failed to get configuration from DHCP"); else Serial.println("DHCP configuration done"); ether.printIp("IP Address:\t", ether.myip); ether.printIp("Netmask:\t", ether.mymask); ether.printIp("Gateway:\t", ether.gwip); } void loop() { ether.packetLoop(ether.packetRe...
// Enter a MAC address and IP address for your controller below. // The IP address will be dependent on your local network: byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDA, 0x02 }; IPAddress ip(191,11,1,1); //<<< ENTER YOUR IP ADDRESS HERE!!! // Initialize the Ethernet ...
用server.begin()开始服务器。你可以用grps.getIPAddress()请求服务器的IP地址,并结束setup。 server.begin(); IPAddress LocalIP = gprs.getIPAddress(); Serial.println("Server IP address="); Serial.println(LocalIP); } [Get Code] 在loop里,创建一个GSMClient实例,并检查是否有任何活动连接 ...
Serial.println("\n[getDHCPandDNS]"); if(Ethernet.begin(mymac) == 0) { Serial.print(F("Failed to configure Ethernet using DHCP\n")); while(1); } else { Serial.print("My IP address: "); for(byte thisByte = 0; thisByte < 4; thisByte++) { ...
以太网络客户端连接程序如下，首先声明保存地址的变量，采用DHCP（动态分配 IP 地址）的代码请参阅下文。#include <SPI.h> #include <Ethernet.h> // 以太网卡的实体地址 byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; IPAddress server(192, 168, 1, 19); // Node 服务器的IP 地址...
Serial.println("IP address: "); Serial.println(WiFi.localIP()); } void loop() { // 获取传感器数据 float sensorData = getSensorData(); // 自定义函数,获取传感器数据 // 创建HTTP请求 String request = "GET /update?data=" + String(sensorData) + " HTTP/1.1\r\n" + ...
=WL_CONNECTED){delay(500);Serial.print(".");}// 产生一个随机种子 因为要生成MQTT 连接时提供IDrandomSeed(micros());Serial.println("");Serial.println("WiFi connected");Serial.println("IP address: ");Serial.println(WiFi.localIP());}//当MQTT推送来消息voidcallback(char*topic,byte*payload,...
Serial.print("\r\nGet IP Address: "); Serial.println(WiFi.localIP()); startTCPClient(); } } } //打开灯泡 //void turnOnLed() { // Serial.println("Turn ON"); // digitalWrite(LED_Pin, LOW); //} 关闭灯泡 //void turnOffLed() { ...
