ST25R3911B Issue with rlafNfcaPollerSelect

Hi I am currently trying to send and receive APDU commands to an NFC PICC. I am using the X-NUCLEO-NFC05A1 (ST25R3911B) and the STM32F401RE Nucleo Board. For software I am using X-CUBE-NFC5  RFAL middleware and STM32CubeF4 HAL.


The Card is a ISO14443A Type 4 ( ISO-DEP)

I can read the UID and Type of the Card, but as soon as I try to select the first card (rfalNfcaPollerSelect), the function responds with timeout error ( 0x04).


I have gone through the RFAL.chm file multiple times and cant seem to find a resolution to my problem. Am I missing some initialization or setting?


Partial Code ( based on example from X-CUBE-NFC5 )


void loop()



      //code for inductive wakeup then run scanA() //(code not shown to save space) 




void scanA()


      rfalNfcaSensRes          sensRes;




      unit16_t err = rfalNfcaPollerTechnologyDetection( RFAL_COMPLIANCE_MODE_NFC_11, &sensRes );

      if (err == 0) //tagfound


       rfalNfcaListenDevice nfcaDevList[1];

       uint8_t             devCnt;

       err= rfalNfcaPollerFullCollisionResolution( RFAL_COMPLIANCE_MODE_NFC_11, 1, nfcaDevList, &devCnt);


      if (nfcaDevList[0].type == RFAL_NFCA_T4T){




void activateIsoDep(rfalNfcaListenDevice lisnDev)


      rfalIsoDepDevice isoDepDevice;

      rfalNfcaSelRes    selRes;


      uint8_t err = rfalNfcaPollerSelect(lisnDev.nfcId1,lisnDev.nfcId1Len,&selRes);  


      //Here I get err = 0x04 (TIMEOUT)


      //       next code for rfalIsoDepPollAHandleActivation
