NTPClient 是一个客户端程序,它使用网络时间协议(NTP)从网络时间服务器获取当前时间。 网络时间协议(NTP):NTP 是一个互联网协议,用于在计算机系统之间同步时钟。 NTPClienttimeClient(ntpUDP,"pool.ntp.org",28800,60000);// GMT+8 时区, 更新间隔 60 秒 pool.ntp.org是一个公共 NTP 服务器池,它会将您的请...

There are many NTP client libraries around. All them have different implementations for time tracking. Indeed I developed one of them. It is called NTPClientLib and was intended to be as easy to use as possible while offering a wide range of features, including multiplatform support (ESP8266,...

然后运行任何使用WiFi的ESP32项目。看看网关输出,它应该显示“Client connected”。这意味着您正在使用专用网关。 如果您的ESP32项目是HTTP服务器,您可以从浏览器进入地址:http://localhost:9080/连接到它。连接将由网关转发到模拟ESP32上的默认HTTP端口(80)。如果您需要转发不同的端口,请open an issue on Github....
