[arduino code examples for AIO Hybrid]-09 how to communication with Tuya Zigbee modul

Code:

#define TUYA_RXD 15

#define TUYA_TXD 48



void setup() {

  Serial0.begin(115200);  // Serial0

  while (!Serial0);



  Serial2.begin(115200, SERIAL_8N1, TUYA_RXD, TUYA_TXD);

  delay(100);



  byte tuya_cmd[] = {0x55, 0xAA, 0x00, 0x00, 0x04, 0x00, 0x00, 0x00, 0x01, 0x00, 0x04};

  Serial0.println("send data to Tuya module:");

  for (int i = 0; i < sizeof(tuya_cmd); i++) {

    Serial0.printf("%02X ", tuya_cmd[i]);

    Serial2.write(tuya_cmd[i]);

  }

  Serial0.println();

}



void loop() {

  if (Serial2.available()) {

    Serial0.print("received from tuya: ");

    while (Serial2.available()) {

      byte b = Serial2.read();

      Serial0.printf("%02X ", b);

    }

    Serial0.println();

  }



  delay(100);
