config ESP_NETIF_IP_LOST_TIMER_INTERVAL
int "IP Address lost timer interval (seconds)"
range 0 65535
default 120
help
The value of 0 indicates the IP lost timer is disabled, otherwise the timer is enabled.
The IP address may be lost because of some reasons, e.g. when the station disconnects
from soft-AP, or when DHCP IP renew fails etc. If the IP lost timer is enabled, it will
be started everytime the IP is lost. Event SYSTEM_EVENT_STA_LOST_IP will be raised if
the timer expires. The IP lost timer is stopped if the station get the IP again before
the timer expires.
