ST25 app not reading URI from NFC01A1

[MasterHans]

I am using a STM32F411RE with a X-Nucleo-NFC01A1 (with the M24SR).

From the X-CUBE-NFC1 package ( https://www.st.com/en/embedded-software/x-cube-nfc1.html ), I adapted the code to my stm32F411RE.

Below is an extract of the main.c

So the TT4_Init() and TT4_WriteURI() returned SUCCESS since the LED 2 and 3 turned ON, However, I can't read the NFC tag using ST25 app, neither with "NFC tools" app from PlayStore.

Is it normal? What can I provide to help?

int main(void)
{
/* USER CODE BEGIN 1 */
sURI_Info URI;
/* USER CODE END 1 */

/* MCU Configuration--------------------------------------------------------*/

/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();

/* USER CODE BEGIN Init */

/* USER CODE END Init */

/* Configure the system clock */
SystemClock_Config();

/* USER CODE BEGIN SysInit */

/* USER CODE END SysInit */

/* Initialize all configured peripherals */
/* USER CODE BEGIN 2 */

// Init of the Nucleo Board led
BSP_LED_Init(LED2);
// Init of the Nucleo Board button
BSP_PB_Init(BUTTON_KEY, BUTTON_MODE_EXTI);

// Init of the M24SR expansion board
initLED();

// Init of the Type Tag 4 component (M24SR)
// Thanks to a call to KillSession command during init no issue can occurs
// If customer modify the code to avoid Kill session command call,
// he must retry Init until succes (session can be lock by RF )
while (TT4_Init() != SUCCESS);

// Set the LED2 on to indicate Init done
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_5, GPIO_PIN_SET); // led 2

// Prepare URI NDEF message content
strcpy(URI.protocol,URI_ID_0x01_STRING);
strcpy(URI.URI_Message,"st.com");
strcpy(URI.Information,"\0");

// First write NDEF
while (TT4_WriteURI(&URI) != SUCCESS);

// Set the LED3 on to indicate Programing done
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_10, GPIO_PIN_SET); // led 3

/* USER CODE END 2 */

/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */

/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}

 Hi,

using the Read memory in the ST25 app, what is the raw content of the NDEF File?

Hello Brian,

I meant that the app doesn't react at all to the NFC tag.

Where can I find Read memory in the ST25 NFC Tap app? I have the 3.9.0 version on Android 12.

I only have those pages on the app:

 

 

 

Clicking on Start NFC setting:

Here is how I2C interface is defined:

void M24SR_I2CInit ( void )
{
	/* check if we re-init after a detected issue */
	if( hi2c1.Instance == M24SR_I2C)
	  HAL_I2C_DeInit(&hi2c1);

  /* Configure I2C structure */
  hi2c1.Instance 	     = M24SR_I2C;
  hi2c1.Init.AddressingMode  = I2C_ADDRESSINGMODE_7BIT;
#if defined (STM32F302x8)
  hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE;
  hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;
  hi2c1.Init.NoStretchMode   = I2C_NOSTRETCH_DISABLE;
#elif defined (STM32F401xE)
  hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLED;
  hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLED;
  hi2c1.Init.NoStretchMode   = I2C_NOSTRETCH_DISABLED;
#endif
  hi2c1.Init.OwnAddress1     = 0;
  hi2c1.Init.OwnAddress2     = 0;
#if (defined USE_STM32F4XX_NUCLEO) || (defined USE_STM32L1XX_NUCLEO) || \
	  (defined USE_STM32F1XX_NUCLEO)
  hi2c1.Init.ClockSpeed      = M24SR_I2C_SPEED;
  hi2c1.Init.DutyCycle       = I2C_DUTYCYCLE_2;
#elif (defined USE_STM32F0XX_NUCLEO) || (defined USE_STM32L0XX_NUCLEO) || \
      (defined USE_STM32F3XX_NUCLEO) || (defined USE_STM32L4XX_NUCLEO)
  hi2c1.Init.Timing          = M24SR_I2C_SPEED;
#endif

	if(HAL_I2C_Init(&hi2c1) != HAL_OK)
  {
    /* Initialization Error */
    Error_Handler();
  }

}

Hi,

the memory tab in the ST25 app is available once a tag has be discovered.

Can you try to read another tag and make sure that the NFC reader on the phone works properly?

Hello Brian,

I was able to make it work : 

The problem was linked to the configuration of the scripts: GPO function and I2C_GPO_INTERRUPT_ALLOWED parameter.

I wasn't using the GPO function to define in main.c from the example which configures the PINs A6 and A7 : 

/**

* @brief GPO initialization for M24SR

*  None

* @retval None

*/

void M24SR_GPOInit ( void )

{

GPIO_InitTypeDef GPIO_InitStruct;



/* GPIO Ports Clock Enable */

INIT_CLK_GPO_RFD();



/* Configure GPIO pins for GPO (PA6)*/

#ifndef I2C_GPO_INTERRUPT_ALLOWED

GPIO_InitStruct.Pin = M24SR_GPO_PIN;

GPIO_InitStruct.Mode = GPIO_MODE_INPUT;

GPIO_InitStruct.Pull = GPIO_NOPULL;

GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;

HAL_GPIO_Init(M24SR_GPO_PIN_PORT, &GPIO_InitStruct);

#else

GPIO_InitStruct.Pin = M24SR_GPO_PIN;

GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;

GPIO_InitStruct.Pull = GPIO_NOPULL;

GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;



HAL_GPIO_Init(M24SR_GPO_PIN_PORT, &GPIO_InitStruct);

/* Enable and set EXTI9_5 Interrupt to the lowest priority */

#if (defined USE_STM32F4XX_NUCLEO) || (defined USE_STM32F3XX_NUCLEO) || \

(defined USE_STM32L1XX_NUCLEO) || (defined USE_STM32F1XX_NUCLEO) || (defined USE_STM32L4XX_NUCLEO)

HAL_NVIC_SetPriority(EXTI9_5_IRQn, 3, 0);

HAL_NVIC_EnableIRQ(EXTI9_5_IRQn);

#elif (defined USE_STM32L0XX_NUCLEO) || (defined USE_STM32F0XX_NUCLEO)

HAL_NVIC_SetPriority(EXTI4_15_IRQn, 3, 0);

HAL_NVIC_EnableIRQ(EXTI4_15_IRQn);

#endif



#endif



/* Configure GPIO pins for DISABLE (PA7)*/

GPIO_InitStruct.Pin = M24SR_RFDIS_PIN;

GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;

GPIO_InitStruct.Pull = GPIO_NOPULL;

HAL_GPIO_Init(M24SR_RFDIS_PIN_PORT, &GPIO_InitStruct);

}

I changed the .ioc file from the CubeIDE project I changed the PA6 and PA7 from Reset_State to GPIO_Output. I don't know if it's relevant since I don't use the generated function MX_GPIO_Init(). Is it?

And TT4_Init() wasn't working because of an unsupported parameter. I found out that I2C_GPO_INTERRUPT_ALLOWED from drv_I2C_M24SR.h was set instead of I2C_GPO_SYNCHRO_ALLOWED.

A comment on the side of I2C_GPO_INTERRUPT_ALLOWED says ! NOT SUPPORTED BY MBED !.

Then it worked.

Many parameters have to be changed when using the examples, and it's hard to find them at first.

I add my main.c main.h and stm32f4xx_hal_msp.c to this reply for the next.

Thanks for the fast reply.

CU soon.
