In above scenario, ideally, the application sockets and the network layer should not be affected, since the Wi-Fi connection only fails temporarily and recovers very quickly. The application can enable "Keep TCP connections when IP changed" via LwIP menuconfig.
WIFI_EVENT_STA_AUTHMODE_CHANGE
++++++++++++++++++++++++++++++++++++
This event arises when the AP to which the station is connected changes its authentication mode, e.g., from no auth to WPA. Upon receiving this event, the event task will do nothing. Generally, the application event callback does not need to handle this either.
IP_EVENT_STA_GOT_IP
++++++++++++++++++++++++++++++++++++
This event arises when the DHCP client successfully gets the IPV4 address from the DHCP server, or when the IPV4 address is changed. The event means that everything is ready and the application can begin its tasks (e.g., creating sockets).
