[Arduino IDE demo source code for KC868-AI]--#06-KC868-AI_RS485_code

Code:

void setup() {
  // put your setup code here, to run once:
Serial2.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
Serial2.println("KinCony");
delay(500);
}

the module does not work for sending via rs485 protocol. how is zero applied to the RE and DE pins MAX13487? there must be either a connection to the DI pin or control of a separate esp32 pin.
