4. When ESP8266 functions as SoftAP, its default IP address is 192.168.4.1. The IP

address is subject to modiﬁcation by developers; however, the DHCP server must be

closed ﬁrst before modifying the address. Below is an example of setting the IP address

as 192.168.5.1.

󰲧󰲧󰲧󰲧Wi-Fi_set_ip_info(SOFTAP_IF,󰲧&info);

5. The range of the IP address allocated by ESP8266 SoftAP can be set by developers.

For example, the IP address can range from 192.168.5.100 to 192.168.5.105. Please

enable the DHCP server when the conﬁguration is completed.
