Android 的 Arduino PN532 卡仿真问题

如何解决Android 的 Arduino PN532 卡仿真问题

我想将我的 PN532 用作 NFC 标签，其中包含一些我的 Android 手机应用程序可以读取和保存的附加数据。不幸的是，android 无法识别模拟标签，如您所见。 我使用示例中的 emulate_tag_ndef。 这是我使用的确切示例：

#include "NdefMessage.h"
#include <SPI.h>
#include <PN532_SPI.h>
#include "PN532.h"
PN532_SPI pn532spi(SPI,10);
EmulateTag nfc(pn532spi);
uint8_t ndefBuf[120];
NdefMessage message;
int messageSize;
uint8_t uid[3] = { 0x12,0x34,0x56 };
void setup()
{
  Serial.begin(115200);
  Serial.println("------- Emulate Tag --------");
  message = NdefMessage();
  //message.addUriRecord("http://www.elechouse.com");
  message.addTextRecord("Hi");
  messageSize = message.getEncodedSize();
  if (messageSize > sizeof(ndefBuf)) {
      Serial.println("ndefBuf is too small");
      while (1) { }
  }  
  Serial.print("Ndef encoded message size: ");
  Serial.println(messageSize);
  message.encode(ndefBuf);  
  // comment out this command for no ndef message
  nfc.setNdefFile(ndefBuf,messageSize);  
  // uid must be 3 bytes!
  nfc.setUid(uid);  
  nfc.init();
}

void loop(){
    // uncomment for overriding ndef in case a write to this tag occured
    //nfc.setNdefFile(ndefBuf,messageSize);    
    // start emulation (blocks)
    nfc.emulate();        
    // or start emulation with timeout
    if(!nfc.emulate(1000)){ // timeout 1 second
      Serial.println("timed out");
    }    
    // deny writing to the tag
    // nfc.setTagWriteable(false);    
    if(nfc.writeOccured()){
       Serial.println("\nWrite occured !");
       uint8_t* tag_buf;
       uint16_t length;       
       nfc.getContent(&tag_buf,&length);
       NdefMessage msg = NdefMessage(tag_buf,length);
       msg.print();
    }
    delay(1000);

}

这是我在 emulatetag.cpp 中的数组

      PN532_COMMAND_TGINITASTARGET,0x0,// MODE: 0x04 = PICC only,0x01 = Passive only (0x02 = DEP only)

      // mifare ParaMS
      0x08,0x00,// SENS_RES (seeeds studio set it to 0x04,nxp to 0x08)
      0x00,// NFCID1t    (is set over sketch with setUID())
      0x60,// SEL_RES    (0x20=mifare DelFire,0x60=custom)

      // FELICA ParaMS
      0x01,0xFE,// NFCID2t (8 bytes)
      0xA2,0xA3,0xA4,0xA5,0xA6,0xA7,0xC0,0xC1,0xC2,0xC3,0xC4,0xC5,0xC6,0xC7,0xFF,0xAA,0x99,0x88,//NFCID3t (10 bytes)
      0x77,0x66,0x55,0x44,0x33,0x22,0x11,// length of general bytes
      0x00  // length of historical bytes
  };

这是我使用带有 NFC 工具或 NXP Tag 信息应用程序的 Android 手机读取模拟卡时的串行输出：

如果我改变了

PN532_COMMAND_TGINITASTARGET,

到

PN532_COMMAND_TGINITASTARGET,0x04,

https://www.nxp.com/docs/en/nxp/application-notes/AN133910.pdf 页中的内容 57 然后我的安卓手机没有反应，什么也没发生

Iphone XR 可搭配使用

所以我不知道我应该在这个数组里面写什么来让我的 android 读取它的内容。 这是默认的：

      PN532_COMMAND_TGINITASTARGET,// NFCID2t (8 bytes) https://github.com/adafruit/Adafruit-PN532/blob/master/Adafruit_PN532.cpp FeliCa NEEDS TO BEGIN WITH 0x01 0xFE!
      0xA2,// length of general bytes
      0x00  // length of historical bytes
  };

如果我使用这个数组，我只能将 PN532 检测为标签

        PN532_COMMAND_TGINITASTARGET,0x05,// MODE: PICC only,Passive only

        0x04,// SENS_RES
        0x0,// NFCID1
        0x20,// SEL_RES

        0,// FeliCaParams
        0,// NFCID3t

        0,// length of general bytes
        0  // length of historical bytes
  };

然后这是我的串行输出：

22:50:02.335 -> Ndef encoded message size: 9
22:50:02.335 -> SAMConfig
22:50:02.335 -> write:  14 01 14 01

如你所见，什么都没有发生......

我还用 Android S8 尝试了整个过程，它的行为类似于 Andoird S20。 我希望有人可以帮助我。

非常感谢您提前提供帮助！
