2SO_KEEPALIVE:使能 TCP keepalive 并且设置 keepalive 用于检查僵尸客户端 使能TCP keepalive 并且设置 keepalive 的参考代码可以参考这里,如下: AI检测代码解析 if (cfg->keep_alive_cfg && cfg->keep_alive_cfg->keep_alive_enable) { int keep_alive_enable = 1; int keep_alive_idle = cfg->keep_al...
此篇博客用来记录ESP32TCP/UDP相关应用层操作。首先列举出几个常用的 setsockopt option: SO_REUSEADDR 启用地址复用,允许 socket 绑定处于 TIME-WAIT 状态的相同端口的 IP 地址 SO_KEEPALIVE 启用 TCP 保活机制,用于服务器或客户端检测链接是否异常,默认值 IDLE:2 小时,INTVL:75 秒,CNT: 9 次 SO ...

Have you tried setting your KeepAlive to somethjng longer? Perhaps 45? Also, I was having issues with PubSub and the current version of espressif32. In the platformio.ini file, I set my platform to: platform = espressif32@^3.5.0 and my connection issues resolved. Good luck! Hi! I´...
