从ST25R3911B发送APDU命令却没有任何响应

tify;text-indent: 40px;">大家好。我正在使用带有STM32-Nuceo-F410RE板的Nucelo-NFC5A1（ST25R3911B）板。
（使用X-Cube-NFC5中间件RFAL）。
我没有从发送到卡的APDU命令得到任何响应。 （也没有我使用的rfalIsoDep函数的错误代码）。
我选择了NFC卡并将其激活。我写了一个函数将APDU命令发送到PICC。
调用rfalIsoDepGetApduTransceiveStatus（）直到它不再忙，我发现rxbufferLength为0。
我希望即使我的APDU命令不正确，我至少应该得到0x90 0x00的响应。
我已将rfalWorker（）添加到我的循环中
rfalIsoDepGetApduTransceiveStatus（）as
我认为它是响应所必需的。另外：根据文档（rfal.chm + x-cube-nfc5.chm），rfal正在修改Txbuffer.prologue，还是我还要配置它？
在任何示例中我都看不到需要配置序言。
代码如下：
错误=
rfalIsoDepPollAHandleActivation
（RFAL_COMPLIANCE_MODE_NFC_11，RFAL_ISODEP_FSXI_512，RFAL_ISODEP_NO_DID，RFAL_BR_424，＆安培; isoDepDevice）;

Hi All. I am Using The Nucelo-NFC5A1(ST25R3911B) board with STM32-Nuceo-F410RE board.
(Using the X-Cube-NFC5 middleware RFAL).
I am not getting any responses from my APDU commands sent to a card. ( Also no Error Codes from the rfalIsoDep functions I use).
I have selected the NFC card and activated it. I have written a function to send the APDU command to the PICC.
After calling the  rfalIsoDepGetApduTransceiveStatus() until it is not busy anymore, I find that the rxbufferLength is 0.
I would expect that even when my APDU command is incorrect, I should at least get a response of 0x90 0x00.
I have added  rfalWorker() into my loop for
rfalIsoDepGetApduTransceiveStatus() as
I assume it is required for the response.Also: According to documentation(rfal.chm + x-cube-nfc5.chm), the rfal is modifying the Txbuffer.prologue, or should I also configure this?
I could not see in any example that the prologue needs to be configured.

code is as folllows:

err =
rfalIsoDepPollAHandleActivation
(RFAL_COMPLIANCE_MODE_NFC_11,RFAL_ISODEP_FSXI_512,RFAL_ISODEP_NO_DID,RFAL_BR_424,&isoDepDevice);
if( err != ERR_NONE ) return false;

rfalIsoDepApduTxRxParam myParam;                     
//Param to be passed to rfalIsoDepStartApduTransceive(param)

rfalIsoDepApduBufFormat apduCommand;            // Struct that contains prologue + APDU Buffer

rfalIsoDepApduBufFormat apduResponse;            // Struct that contains prologue + APDU Buffer

uint8_t DDF2[] = '2PAY.SYS.DDF01';

uint8_t headerLen = 5;
uint16_t
ddflen = sizeof(DDF2);

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

myParam.DID = isoDepDevice.info.DID;

myParam.ourFSx = isoDepDevice.info.FSx;

myParam.rxBuf = &

myParam.rxBufLen = &myADPURxLen;

myParam.txBufLen = ddflen;

);


for (uint8_t b=0;b<30;b++)

{

             result =
rfalIsoDepGetApduTransceiveStatus();

             if (result == ERR_BUSY) {

                  logUsart('.');

                   HAL_Delay(250);

                   }

             if (result == ERR_NONE) {

                   logUsart('RX Done rn');

                  break;

                   }   

}

logUsart('R-APDU responded with %d Bytes rn',
myADPURxLen
);
//Here I receive 0 Bytes in the rxBuflen field
