lwip是一层纯软件,轻量级TCP/IP协议栈; esp_netif是esp官方提供的操作TCP/IP协议栈的API 原文链接:https://blog.csdn.net/qq_34473570/article/details/108560904
后来经过查找资料，发现我这里定义的Boy是main中的内部类，
It is pretty much working but I get this error when going to the access point. E (762367) esp_netif_lwip: esp_netif_new: Failed to configure netif with config=0x3fce53b4 (config or if_key is NULL or duplicate key) Below is the code in setup() to initialize the scan. ...

1. esp32的esp_wifi(wifi驱动库),esp_netif(网络接口) ,lwip(轻量级TCP/IP网络协议栈)是什么?三者之间有什么关系? esp_wifi驱动库用户控制wifi硬件单元; lwip是一层纯软件,轻量级TCP/IP协议栈; esp_netif是esp官方提供的操作TCP/IP协议栈的API。 从上面的ESP32功能框图中可以看出wifi是单片机中的一... ...
多个netif生效时无法指定getaddrinfo走哪个netifby ShunzDai » Tue Feb 27, 2024 11:15 am 当前有eth和sta两个netif, 业务逻辑需要用其中一个netif去ping服务器域名, 来判断这个netif是否可用. 但在eth是局域网, sta连入互联网的情况下, 此时应该选择使用sta, 但发现此时getaddrinfo解析不了服务器域名, ...

It is simplest example to show how to use ethernet over USB with usb-netif component. Build and flash example, connect board to PC with USB cable (its native USB, not CP210x on board), and then open http://192.168.4.1/ web page in the browser. We should see logs like this: I (...
