Troubles UART

[ksarz]

1. do you understand me? change network adapter option.

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

Sorry,I do not understand it.
Pin "A" on the board is the  RS485 RXD: 14  and Pin "B" is the  RS485 TXD: 27.
Yes or NOT???
