Sending a select apdu message to a phone using st25r3911b

[rabinniroula]

I have ported rfal platform to work on my esp32 and have successfully detected all kinds of cards. Now I want to send select APDU message to the phone but I am unsucessful at doing so.

The code I have used:

err = rfal_nfc.rfalIsoDepPollAHandleActivation(RFAL_ISODEP_FSXI_512, RFAL_ISODEP_NO_DID, RFAL_BR_424, &isoDepDev);
Serial.print("handle activation: ");
Serial.println(err);

err = rfal_nfc.rfalIsoDepStartApduTransceive(param);
Serial.print("APDU txrx error: ");
Serial.println(err);

if (err == ERR_NONE)
{
  do
  {
    rfal_nfc.rfalNfcWorker();
    err = rfal_nfc.rfalIsoDepGetApduTransceiveStatus();
    Serial.print(".");
    // delay(200);
    Serial.print(err);
  } while (err == ERR_BUSY);
  Serial.println("Received!");
  Serial.println(rxLen);
}

The param I've used is:

rfalIsoDepApduTxRxParam param;
rfalIsoDepApduBufFormat txapdu;
rfalIsoDepApduBufFormat rxapdu;
rfalIsoDepApduBufFormat temp;
uint16_t rxLen;
txapdu.apdu[0] = SELECT_APDU[0];
txapdu.apdu[1] = SELECT_APDU[1];
txapdu.apdu[2] = SELECT_APDU[2];
txapdu.apdu[3] = SELECT_APDU[3];
txapdu.apdu[4] = SELECT_APDU[4];
txapdu.apdu[5] = SELECT_APDU[5];
txapdu.apdu[6] = SELECT_APDU[6];
txapdu.apdu[7] = SELECT_APDU[7];
txapdu.apdu[8] = SELECT_APDU[8];
txapdu.apdu[9] = SELECT_APDU[9];
txapdu.apdu[10] = SELECT_APDU[10];
txapdu.apdu[11] = SELECT_APDU[11];
txapdu.apdu[12] = SELECT_APDU[12];
param.txBuf = &txapdu;
param.txBufLen = sizeof(txapdu);
param.rxBuf = &rxapdu;
param.rxLen = &rxLen;
param.FWT = isoDepDev.info.FWT;

param.dFWT = isoDepDev.info.dFWT;

param.FSx = RFAL_ISODEP_FSX_KEEP;      

//myParam.FSx = isoDepDevice.info.FSx;

param.DID = isoDepDev.info.DID;  
param.ourFSx = isoDepDev.info.FSx; 

The rxLen I get is always 42405. I couldn't find any examples to transceive apdu messages. Can you please help me? Thank you
