RFID integration

[Arjun_Bansal]

i am trying to connect "RFID YHY502CTG" with STM32F407G-DISC1,i have attached the datasheet of RFID,please help me to send and receive data. i am using this code in while loop.

while (1)

{

/* USER CODE END WHILE */

 

/* USER CODE BEGIN 3 */

Txdata[0]=0xAA;

Txdata[1]=0xBB;

Txdata[2]=0x02;

Txdata[3]=0x01;

Txdata[4]=0x03;

 

 

HAL_UART_Transmit(&huart1, Txdata, sizeof(Txdata),100);

HAL_UART_Receive(&huart1, Rxdata, sizeof(Rxdata),100);

}

 

i have intialized these two buffers

uint8_t Txdata[5];

uint8_t Rxdata[20];
