Problems accesing the 192.168.4.1 browser for MQTT configuration

[admin]

if you download KCS firmware for KC868-A6. after download reboot, you will see AP hotspot named KC868-A6xxxxxxxx. use your laptop connect to KC868-A6 by wifi. Then you can login by web browser by 192.168.4.1 , go to "network" page, set wifi mode= STA, set your router's ssid and password. after reboot, AP hotspot will not work, then you can use UDP_SCAN tool to find the board's IP.
