I am trying to communicate with NRF52832 on MRFC522 vscode. My Write and Read functions are not working

Question

Below I have my read and write functions. Are my SPI configuration settings correct? I want to read the RFID card ID value.

MAİN.C

#include <zephyr/drivers/gpio.h>

#include <zephyr/drivers/SPi.h>
#include "MRFC522.h"



/* The devicetree node identifier for the "led0" alias. */
#define LED0_NODE DT_ALIAS(led0)
uint8_t ID[5];
/*
 * A build error on this line means your board is unsupported.
 * See the sample documentation for information on how to fix this.
 */
static const struct gpio_dt_spec led = GPIO_DT_SPEC_GET(LED0_NODE, gpios);

int main(void)
{
	int ret;
SPI_Init();
TM_MFRC522_Init();
	if (!gpio_is_ready_dt(&led)) {
		return 0;
	}

	ret = gpio_pin_configure_dt(&led, GPIO_OUTPUT_ACTIVE);
	if (ret < 0) {
		return 0;
	}

	while (1) {

    if ((TM_MFRC522_Check(ID) == MI_OK))
	{
		gpio_pin_toggle_dt(&led);
printk(" [%02x%02x%02x%02x%02x]\n\r\n", ID[0], ID[1], ID[2], ID[3], ID[4]);
	}

	
	
	}
	return 0;
}

Dear damar 
 Thank you for providing the sample. I was able to read the UID of the card based on what you provided. 
 My current issue is that I cannot read the data in the blocks of the card. 
 Hardware: nRF52DK, MFRC522, MIFARE 1K. Function Read data on Block 6

void ReadBlock6(uint8_t *cardUID)
{
 uint8_t defaultKeyA[6] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF};
 uint8_t buffer[16] = {0};
 printf("cardUID: %02X-%02x-%02x-%02x 
", cardUID[0], cardUID[1], cardUID[2], cardUID[3]);
 if (TM_MFRC522_Auth(PICC_AUTHENT1A, 6, defaultKeyA, cardUID) == MI_OK)
 {
 TM_MFRC522_ReadBlock(6, buffer);
 }
 else
 {
 printf("[ERROR] Khong the doc block 6 do loi authen
");
 }
}
uint8_t TM_MFRC522_Auth(uint8_t authMode, uint8_t blockAddr, uint8_t *sectorKey, uint8_t *cardUID)
{
 uint8_t buff[12];

buff[0] = authMode; // Loại x&#225;c thực (PICC_AUTHENT1A hoặc PICC_AUTHENT1B)
 buff[1] = blockAddr; // Block cần x&#225;c thực

// Copy key 6 byte
 for (uint8_t i = 0; i < 6; i++)
 {
 buff[i + 2] = sectorKey[i];
 }

// Copy UID (4 byte)
 for (uint8_t i = 0; i < 4; i++)
 {
 buff[i + 8] = cardUID[i];
 }

// Gửi lệnh đến thẻ
 uint8_t status = 1;
 printk("buff: %X-%X-%X-%X-%X-%X-%X-%X-%X-%X-%X-%X
", buff[0], buff[1], buff[2], buff[3], 
 buff[4], buff[5], buff[6], buff[7], buff[8], buff[9], buff[10], buff[11]);
 status = TM_MFRC522_ToCard(PCD_AUTHENT, buff, 12, NULL, NULL);
 printk("Authen status: %d
", status);
 if (status != MI_OK)
 {
 printf("[ERROR] Authen that bai block %d
", blockAddr);
 }
 else
 {
 printf("[INFO] Authen thanh cong block %d
", blockAddr);
 }

return status;
}

TM_MFRC522_STS_T TM_MFRC522_ReadBlock(uint8_t blockAddr, uint8_t *buffer)
{
 TM_MFRC522_STS_T status;
 uint8_t sendData[2];
 uint16_t recvLen;

printf("[INFO] Dang doc du lieu tu block: %d
", blockAddr);

sendData[0] = PICC_READ; // Lenh doc block
 sendData[1] = 6; // Dia chi block can doc

printf("[DEBUG] Gui lenh doc: 0x%02X 0x%02X
", sendData[0], sendData[1]);

// Gui lenh doc block den the
 status = TM_MFRC522_ToCard(PCD_TRANSCEIVE, sendData, 2, buffer, &recvLen);

if (status != MI_OK)
 {
 printf("[ERROR] Khong the doc block %d!
", blockAddr);
 return MI_ERR;
 }

if (recvLen != (MFRC522_MAX_LEN + 2))
 {
 printf("[ERROR] So byte nhan duoc khong dung! Nhan: %d, Ky vong: %d

 return MI_ERR;
 }

printf("[INFO] Du lieu tu block %d: ", blockAddr);
 for (int i = 0; i < MFRC522_MAX_LEN; i++)
 {
 printf("%02X ", buffer[i]);
 }
 printf("

return MI_OK;
