Hello,
I'm using ST25R3911 with my own board, and I need to read a ISO14443A/NFC-A T2T card, like NTAG213/6. I'm using the ST25R3911 DISCO FW 1.28 files.
The card is correctly detected, and I'm able to read the UID, but when I try to select the sector to read using the rfal_t2t files (rfalT2TPollerSectorSelect function) I obtain a 04 error due to timeout.
My function:
bool PollNFCA()
{
ReturnCode err;
rfalNfcaSensRes sensRes;
rfalNfcaSelRes selRes;
rfalNfcaListenDevice nfcaDevList[EXAMPLE_NFCA_DEVICES];
uint8_t devCnt;
uint8_t devIt;
bool found = false;
rfalNfcaPollerInitialize(); // Initialize RFAL for NFC-A
rfalFieldOnAndStartGT(); // Turns the Field On and starts GT timer
//----------------------------------------------------------------------------
// Perform NFC-A Technology detection
err = rfalNfcaPollerTechnologyDetection( RFAL_COMPLIANCE_MODE_NFC, &sensRes ); // Poll for nearby NFC-A devices
if(err == ERR_NONE) // NFC-A type card found
{
err = rfalNfcaPollerFullCollisionResolution( RFAL_COMPLIANCE_MODE_NFC, 1, nfcaDevList, &devCnt);
if ( (err == ERR_NONE) && (devCnt > 0) )
{
found = true;
printf("NFC-A device(s) found %d\r\n", devCnt );
devIt = 0; // Use the first device on the list
//----------------------------------------------------------------------------
// Check if desired device is in Sleep
if( nfcaDevList[devIt].isSleep )
{
err = rfalNfcaPollerCheckPresence( RFAL_14443A_SHORTFRAME_CMD_WUPA, &sensRes ); // Wake up all cards
if( err != ERR_NONE )
{
return false;
}
err = rfalNfcaPollerSelect( nfcaDevList[devIt].nfcId1, nfcaDevList[devIt].nfcId1Len, &selRes ); // Select specific device
if( err != ERR_NONE )
{
return false;
}
}
printf("ISO14443A/NFC-A card found. UID: %s\r\n", hx2Str(nfcaDevList[0].nfcId1, nfcaDevList[0].nfcId1Len));
if(nfcaDevList[devIt].type == RFAL_NFCA_T2T) // Perform protocol specific activation
{
/* NFC-A T2T device found, NFCID/UID is contained in: nfcaDev.nfcid */
/* Following communications shall be performed using:
* * - Non blocking: rfalStartTransceive() + rfalGetTransceiveState()
* * - Blocking: rfalTransceiveBlockingTx() + rfalTransceiveBlockingRx() or rfalTransceiveBlockingTxRx() */
err = rfalT2TPollerSectorSelect(4);
if( err != ERR_NONE )
{
printf(" error: %d Exit...\r\n", err);
return false;
}
}
}
}
return found;
}
Thanks
