KC868-A32 I2C communication with arduino

[SixSixOne]

i don't suggest to control by i2c. you can use by RS485 connect to other device.
if you MUST want use by i2c. OK, just add your i2c device driver into arduino main program code.

Thank you for your reply.
May I have the correct tx / rx for UART of the KC868-A32 module?

uart:
  baud_rate: 9600
  debug:
    direction: BOTH
    dummy_receiver: true
    after:
      timeout: 10ms
  tx_pin: XX
  rx_pin: XX

Tks a lot
