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... ...

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, 如果卸载掉rth的netif则getaddrinfo可以解析服务器域名. 尝试清除dns cache也无法解决. 有人遇到类似...

For debugging purposes, if I change esp_netif_dhcps_stop() to esp_netif_dhcpc_stop(), the code compiles and runs, but I get a failure when I try to set the static IP address in my AP. Thanks. 1 post • Page1of1 Return to “ESP-IDF” ...
Netif with wifi in APSTA modeby ecktello » Tue Jun 27, 2023 2:45 am Hello all, I'm configuring wifi to be in APSTA mode to run a webserver. One question I have is when I use esp_netif_init(), can I use esp_netif_create_default_wifi_sta() and esp_netif_create_default_...
