我确实了解目的，但您需要如何将命令发送到ACR122u。

据我所知FF000000意味着：

• FF [班级]
• 00 [INS]
• 00 [P1]
• 00 [P2]

我只是不知道如何发送实际的PN532命令，例如：

• FF000000 08 D406 6305 630D 6338
• FF000000 11 D408 6302 80 6303 80 6305 xx 630D yy 6338 zz

我走了这么远：

    TerminalFactory factory = TerminalFactory.getDefault();
    List<CardTerminal> terminals;

    try {
            terminals = factory.terminals().list();

            CardTerminal terminal   = terminals.get(0);
            Card card               = terminal.connect("*");
            CardChannel channel     = card.getBasicChannel();
            byte[] command          = {???};
            CommandAPDU command1    = new CommandAPDU(0xFF,0x00,0x00,0x00, command);
            ResponseAPDU response1  = channel.transmit(command1);
            System.out.println(bytesToHex(response1.getBytes()));

    } catch (CardException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

我感谢您的帮助！

提前谢谢了！！
