Android HCE与Arduino和Galaxy S3 cyanogenmod 11

我目前正在尝试让我的arduino uno设备运行HCE,该设备安装了一个看起来不错的NFC Shield V 2.0

我使用的是 https://github.com/Seeed-Studio/PN532/blob/master/PN532/examples/android_hce/android_hce.ino

#include <SPI.h>
#include <PN532_SPI.h>
#include <PN532Interface.h>
#include <PN532.h>

PN532_SPI pn532spi(SPI, 10);
PN532 nfc(pn532spi);


void setup()
{
    Serial.begin(115200);
    Serial.println("-------Peer to Peer HCE--------");

    nfc.begin();

    uint32_t versiondata = nfc.getFirmwareVersion();
    if (! versiondata) {
      Serial.print("Didn't find PN53x board");
      while (1); // halt
    }

    // Got ok data, print it out!
    Serial.print("Found chip PN5"); Serial.println((versiondata>>24) & 0xFF, HEX);
    Serial.print("Firmware ver. "); Serial.print((versiondata>>16) & 0xFF, DEC);
    Serial.print('.'); Serial.println((versiondata>>8) & 0xFF, DEC);

    // Set the max number of retry attempts to read from a card
    // This prevents us from waiting forever for a card, which is
    // the default behaviour of the PN532.
    //nfc.setPassiveActivationRetries(0xFF);

    // configure board to read RFID tags
    nfc.SAMConfig();
}

void loop()
{
  bool success;

  uint8_t responseLength = 32;

  Serial.println("Waiting for an ISO14443A card");

  // set shield to inListPassiveTarget
  success = nfc.inListPassiveTarget();

  if(success) {

     Serial.println("Found something!");

    uint8_t selectApdu[] = { 0x00, /* CLA */
                              0xA4, /* INS */

                              0x00  /* Le  */ };

    uint8_t response[32];

    success = nfc.inDataExchange(selectApdu, sizeof(selectApdu), response, &responseLength);

    if(success) {

      Serial.print("responseLength: "); Serial.println(responseLength);

      nfc.PrintHexChar(response, responseLength);

      do {
        uint8_t apdu[] = "Hello from Arduino";
        uint8_t back[32];
        uint8_t length = 32;

        success = nfc.inDataExchange(apdu, sizeof(apdu), back, &length);

        if(success) {

          Serial.print("responseLength: "); Serial.println(length);

          nfc.PrintHexChar(back, length);
        }
        else {

          Serial.println("Broken connection?");
        }
      }
      while(success);
    }
    else {

      Serial.println("Failed sending SELECT AID");
    }
  }
  else {

    Serial.println("Didn't find anything!");
  }

  delay(1000);
}

void printResponse(uint8_t *response, uint8_t responseLength) {

   String respBuffer;

    for (int i = 0; i < responseLength; i++) {

      if (response[i] < 0x10)
        respBuffer = respBuffer + "0"; //Adds leading zeros if hex value is smaller than 0x10

      respBuffer = respBuffer + String(response[i], HEX) + " ";
    }

    Serial.print("response: "); Serial.println(respBuffer);
}

void setupNFC() {

  nfc.begin();

  uint32_t versiondata = nfc.getFirmwareVersion();
  if (! versiondata) {
    Serial.print("Didn't find PN53x board");
    while (1); // halt

我的android代码取自HCE开发指南,我也尝试了代码形式 https://github.com/grundid/host-card-emulation-sample

我的问题是,arduino代码甚至不能识别标签。所以我得到的只是:

Waiting for an ISO14443A card
Didn't find anything!
Waiting for an ISO14443A card
Didn't find anything!
Waiting for an ISO14443A card 

事实上,在Android方面,我没有收到任何数据包,也没有收到花哨的NFC声音播放,这通常表明至少发生了什么。 所以我的问题是,是否有人尝试使用cyanogenmod 10和HCE支持的Galaxy S3。我真的没有任何想法,我三次检查了我的代码,在SO上读了很多问题,但所有人都至少从NFC屏蔽收到了一些东西。

我知道普通NFC模式工作正常,因为我有一个应用程序在“正常”模式下使用NFC。当我在arduino上运行此NFC协议时,所有应用程序都会收到一个数据包(尽管它们无法正确路由,因为它们不是adpu数据包)
