ACR122u卡仿真模式发送PN532命令 [英] ACR122u card-emulation mode send PN532 commands

问题描述

我刚刚阅读了此答案，该答案关于如何将ACR122U置于卡仿真模式.我确实了解目的，但是您需要如何将命令发送到ACR122u.

I just read this answer about how to put my ACR122U in card-emulation mode. I do understand the purpose but how do you need to send the commands to the ACR122u.

据我所知FF000000表示:

As far as I know FF000000 means:

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

例如，我只是不知道如何发送实际的PN532命令:

I just can't figure out how I can send the actual PN532 command for example:

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

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

我已经走了这么远:

    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();
    }

感谢您的帮助！

非常感谢！

推荐答案

假设 08 D406 6305 630D 6338 表示

• 08 [Lc]
• D406 6305 630D 6338 [数据]

它看起来像这样:

byte[] command = new byte[8] { (byte) 0xD4, 0x06, 0x63, 0x05, 0x63, 0x0D, 0x63, 0x38 };

您可以省去8，因为javac会为您计数字节.

You can leave out the the 8 since javac will count the bytes for you.
