Usage Example for Arduino-Module Status Exchange

Hardware Preparation

• ID01 UHF RFID Reader-UART(SKU: TEL0082) ×1
• DFRduino UNO R3 (SKU: DFR0216) × 1
• USB Cable × 1

Wiring Diagram

The wire definition of UHF RFID MODULE-UART is:

• red：Input 7V/2A
• black：GND
• green：TX end
• yellow：RX end

Notes: When connect with arduino board using chip ATmega328P, please exchange the TX/RX port if you want to send command from usb terminal.

Sample Code

This sample shows that using Arduino to control the status exchanging between “Stop reading tags” and “Restart tag identification function”.

unsigned char StopReadCode[5] = {0xa0,0x03,0xa8,0x00,0xb5};//Stop reading the label code
unsigned char ResetCode[5]={0xa0,0x03,0x65,0x00,0xf8};//Reset code
unsigned char StopReadCodeCB[6]={0xe0,0x04,0xa8,0x00,0x00,0x74};//Stop reading code success and return the value
unsigned char ResetCodeCB[6]={0xe4,0x04,0x65,0x00,0x00,0xb3};//Reset code success and return the value
unsigned char data[6]={};
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int i;
  int n=1;
  delay(2000);
  while(n)
  {
    Serial.write(StopReadCode,5);
    delay(200);
    if(Serial.available())
    {
      for(i=0;i<6;i++)
      {
        data[i]=Serial.read();
        delay(1);
      }
      for(i=0;i<6;i++)
      {
        if(data[i]==StopReadCodeCB[i])
          n=0;
        else
          n=1;
      }
    }
    delay(500);
  }
  n=1;
  while(n)
  {
    Serial.write(ResetCode,5);
    delay(200);
    if(Serial.available())
    {
      for(i=0;i<6;i++)
      {
        data[i]=Serial.read();
        delay(1);
      }
      for(i=0;i<6;i++)
      {
        if(data[i]==ResetCodeCB[i])
          n=0;
        else
          n=1;
      }
    }
    delay(500);
  }
