I have updated sdk to the latest version with git The connection to the WiFi remains active for a time ranging from 30 seconds to 6 hours. The module disconnects and reconnects by the connectDeviceToWiFi () function. I tried to lower the time beecon in the router. Now it's every 30 ...

changedConnectionCallback()函数:负责通知 ESP-MESH 网络连接出现变化,比如有设备离线或有新设备加入等; nodeTimeAdjustedCallback()函数:负责打印时间同步信息,以确保 ESP-MESH 网络中所有设备的时间是同步的。 setup() 初始化设置 在setup() 初始化程序中,先初始化串口,方便后面打印信息。
