We can have multiple clients and a single host server, such as the ESP32 or any IoT development board. Now, the question is how a web client can access the web server hosted on the ESP32. When a device connects to a network, it is assigned an IP address. We can use this assigned ...

要结束ESP32上的AsyncWebServer,请遵循以下步骤: 首先,确保您已经包含了必要的库和初始化了服务器。在代码的开始部分,包含库并初始化一个AsyncWebServer实例。例如: 代码语言:javascript 复制 #include <WiFi.h> #include <ESPAsyncWebServer.h> const char* ssid = "your_SSID"; const char* password = "you...
