I am trying to change the adress of these sensors with the next code. After using it, the blue LED in the sensor has not worked again. I would like to know if the sensor is broken or if I can fix it and how.

// # Pin VCC (URM07 V1.0) -> D3 (Arduino Leonardo)

// # Pin GND (URM07 V1.0) -> D2 (Arduino Leonardo)

// # Pin RX (URM07 V1.0) -> TX1/D1 (Arduino Leonardo)

// # Pin TX (URM07 V1.0) -> RX1/D0 (Arduino Leonardo)

#define header_H 0x55 //Header

#define header_L 0xAA //Header

#define device_Addr 0xAB //Address

#define data_Length 0x01 //Data length

#define set_adress_CMD 0x55 //Command: Set adress

#define set_adress 0x05 //Command: Change adress

#define checksum (header_H+header_L+device_Addr+data_Length+set_adress_CMD+set_adress) //Checksum

unsigned char i=0;

unsigned char Adress=0;

unsigned char Operation_confirmed=0;

unsigned char Rx_DATA[8];

unsigned char CMD[7]={

header_H,header_L,device_Addr,data_Length,set_adress_CMD,set_adress,checksum}; //Distance command package

void setup() {

pinMode(2, OUTPUT);

pinMode(3, OUTPUT);

digitalWrite(3, HIGH); //Ultrasonic VCC

digitalWrite(2, LOW); //Ultrasonic GND

Serial1.begin(19200); //Serial1: Ultrasonic Sensor Communication Serial Port, Buadrate: 19200

Serial.begin(19200); //Serial: USB Serial Data output, baudrate: 19200

}

void loop() {

for(i=0;i<7;i++){

Serial1.write(CMD[i]);

}

delay(150); //Wait for the result

i=0;

while (Serial1.available()){ //Read the return data (Note: this demo is only for the reference, no data verification)

Rx_DATA[i++]=(Serial1.read());

}

Adress=(Rx_DATA[2]);

Operation_confirmed=(Rx_DATA[5]);

if (Operation_confirmed == 0xCC){

Serial.println("Operation completed");

}

else{

Serial.println("Operation Failed");

}

delay(1000);

Serial.println(Adress);

}

If you are not sure of its usage, there is a document in which all the data is explained.

Thanks!!
