you should use PC connect to KC868-A6 wifi hotspan firstly. please see KCS v2 onlie guide firstly, how to set wifi.
Note: if you want config only by WiFi, when power on, your computer will find the “AP” hotspot, WiFi signal named “board name” + “ID”.

Let your computer connect to the “AP”, it’s without password, after you connected, just use http://192.168.4.1 to login by webpage.
If you can’t see the “AP”, you can “hold on” board’s function button (ESP32 GPIO0) >10 seconds, then board will be set to factory, default state is “AP”.

after you connect pc with kc868-a6 board by wifi hotspot, set STA mode, then check ip by scan device tool. please see online guide firstly: https://www.kincony.com/esp32-kcsv2-firmware.html
2. A and B use by RS485, not serial port.
RS485 RXD: 14
RS485 TXD: 27
extend serial port use by GPIO12,GPIO13 on pcb
Pin "A" on the board is the RS485 RXD: 14 and Pin "B" is the RS485 TXD: 27.
Yes or NOT???
