因此,在本文中,我们将通过使用ESP32制作一个web服务器来解决这个问题,该服务器将运行WebSocket通信协议,当发生更改时,它将通知所有客户端,并且网页将立即更新。我们可以使用ESP32 WebSocket Server实现两个ESP32之间的稳定通信。 什么是Websocket? 回到WWW(万维网)的黑暗时代,任何时候你想要更新网页上的任何内容,你都必...
In this tutorial, we will learn to create a simple web server with ESP32 using Arduino IDE framework. It will host HTML and CSS files and serve them to clients whenever it receives an HTTP GET request from any web client ( web browser). We can use this ESP32 web server to control GP...
Github上那么多Websocket库,用过两个star最多的,一个连接太慢,握手需要1700~1900ms(应该是90~110ms),另一个用作服务器的时候内存泄漏,所以自己做了一个Websocket,简单好用,配合Espressif官方esp32-arduino框架使用非常方便,有需要的朋友可以自己下载使用。 地址:https://github.com/vidalouiswang/Arduino_ESP32_Web...
In one of our previous articles, we have built such anESP32 based WebSocket serverthat can host a webpage and send updates without completely refreshing the page. Doing so made us wonder if there is any way for us to configure theESP32 as a clientthat can connect to the server ov...
开源教程:第十六章 ESP32的TCP连接。 编程指南:lwIP,lwip是嵌入式的简约版tcp/ip协议,开源且轻量级(个人理解)。 一、例程实践 官方例程:examples/protocols/sockets/目录下的tcp_client/,github传送门链接。 官方例程②:examples/protocols/asio/目录下的tcp_echo_server/,github传送门链接。
webSocketServer.sendData(data); } delay(10); // Delay needed for receiving the data correctly } Serial.println("The client disconnected"); delay(100); } delay(100); } Testing the code To test the code, first compile it and upload it to your ESP32 using the Arduino IDE. After the pr...

One can easily get overwhelmed when starting with ESP32 WiFi by the number of topics and libraries out there (e.g HTTP, TCP/IP, UDP, WebServers, AsyncWebServers, WebSocket, MQTT, mDNS, MESH, ESP-NOW, etc…). There are too many libraries, modes, topologies, and protocols that make ...
