DESCRIPTION

Constants used within RFID::Libnfc

CATEGORIES

  • NDO

    NDO_HANDLE_CRC => 0x00,
    Let the PN53X chip handle the CRC bytes. This means that the chip appends
    the CRC bytes to the frames that are transmitted. It will parse the last
    bytes from received frames as incoming CRC bytes. They will be verified
    against the used modulation and protocol. If an frame is expected with
    incorrect CRC bytes this option should be disabled. Example frames where
    this is useful are the ATQA and UID+BCC that are transmitted without CRC
    bytes during the anti-collision phase of the ISO14443-A protocol. 

NDO_HANDLE_PARITY => 0x01,
    Parity bits in the network layer of ISO14443-A are by default generated and
    validated in the PN53X chip. This is a very convenient feature. On certain
    times though it is useful to get full control of the transmitted data. The
    proprietary MIFARE Classic protocol uses for example custom (encrypted)
    parity bits. For interoperability it is required to be completely
    compatible, including the arbitrary parity bits. When this option is
    disabled, the functions to communicating bits should be used. 

NDO_ACTIVATE_FIELD => 0x10,
    This option can be used to enable or disable the electronic field of the
    NFC device. 

NDO_ACTIVATE_CRYPTO1 => 0x11,
    The internal CRYPTO1 co-processor can be used to transmit messages
    encrypted. This option is automatically activated after a successful MIFARE
    Classic authentication. 

NDO_INFINITE_SELECT => 0x20,
    The default configuration defines that the PN53X chip will try indefinitely
    to invite a tag in the field to respond. This could be desired when it is
    certain a tag will enter the field. On the other hand, when this is
    uncertain, it will block the application. This option could best be compared
    to the (NON)BLOCKING option used by (socket)network programming. 

NDO_ACCEPT_INVALID_FRAMES => 0x30,
    If this option is enabled, frames that carry less than 4 bits are allowed.
    According to the standards these frames should normally be handles as
    invalid frames. 

NDO_ACCEPT_MULTIPLE_FRAMES => 0x31,
    If the NFC device should only listen to frames, it could be useful to let
    it gather multiple frames in a sequence. They will be stored in the internal
    FIFO of the PN53X chip. This could be retrieved by using the receive data
    functions. Note that if the chip runs out of bytes (FIFO => 64 bytes long),
    it will overwrite the first received frames, so quick retrieving of the
    received data is desirable. 

NDO_AUTO_ISO14443_4 => 0x40,
    This option can be used to enable or disable the auto-switching mode to
    ISO14443-4 is device is compliant.
    In initiator mode, it means that NFC chip will send RATS automatically when
    select and it will automatically poll for ISO14443-4 card when ISO14443A is
    requested.
    In target mode, with a NFC chip compiliant (ie. PN532), the chip will
    emulate a 14443-4 PICC using hardware capability 

NDO_EASY_FRAMING => 0x41,
    Use automatic frames encapsulation and chaining. 

NDO_FORCE_ISO14443_A => 0x42,
    Force the chip to switch in ISO14443-A
