我正在尝试从我的pcsc java代码中读取卡UID/HCE android设备 UID。但是我收到以下错误
javax.smartcardio.CardException: sun.security.smartcardio.PCSCException: Unknown error 0x1f
虽然当我尝试获取 UID 时我能够获得 ATS 位，但出现此错误。我从这里引用了我的代码

已经参考了以下内容通过SCL010获得Mifare超轻型的UID
请帮忙！
谢谢
我能够通过更改命令 APDU 找到解决方案并获取 UID。然后我将结果字节[]转换为十六进制UID。
try {
//get UID cmd apdu
ResponseAPDU answer = cc.transmit( new CommandAPDU(new byte[] { (byte)0xFF, (byte)0xCA, (byte)0x00, (byte)0x00, (byte)0x00 } ));
System.out.println("answer: " + answer.toString());
byte[] reponseBytesArr=answer.getBytes();
System.out.println("answer byte[]");
StringBuilder sb = new StringBuilder();
for(int i=0;i<reponseBytesArr.length;i++){
//print arr
byte b =reponseBytesArr[i];
System.out.println(b);
if(i<=reponseBytesArr.length-3){
// append uid
sb.append(String.format("%02X ", b));
}
}
System.out.println("UID: "+sb.toString());
