Detailed Description

ISO Data Exchange Protocol.

Constructor & Destructor Documentation

IsoDEP() [1/2]

m5::nfc::isodep::IsoDEP::IsoDEP ( NFCLayerInterface & layer )

inlineexplicit

Constructor with NFC layer.

Parameters

layer

NFC layer interface

IsoDEP() [2/2]

m5::nfc::isodep::IsoDEP::IsoDEP ( NFCLayerInterface & layer, const config_t & c )

inline

Constructor with NFC layer and configuration.

Parameters

layer	NFC layer interface
c	ISO-DEP configuration

Member Function Documentation

config() [1/2]

config_t m5::nfc::isodep::IsoDEP::config ( ) const

inline

Get configuration.

Returns

Current ISO-DEP configuration

config() [2/2]

void m5::nfc::isodep::IsoDEP::config ( const config_t & cfg )

inline

Set configuration.

Parameters

cfg	New ISO-DEP configuration

Note

Resets the ISO-DEP block number

transceive()

bool m5::nfc::isodep::IsoDEP::transceive	(	uint8_t *	rx,
		uint16_t &	rx_len,
		const uint8_t *	tx,
		const uint16_t	tx_len,
		const uint32_t	timeout_ms )

Transceive normal.

Parameters

[out]	rx	Receive buffer
[in,out]	rx_len	In: capacity of rx, Out: received length
	tx	Transmit buffer
	tx_len	Transmit length
	timeout_ms	Timeout in milliseconds

Returns

True if succeeded

transceiveAPDU()

bool m5::nfc::isodep::IsoDEP::transceiveAPDU	(	uint8_t *	rx,
		uint16_t &	rx_len,
		const uint8_t *	cmd,
		const uint16_t	cmd_len,
		const policy_t *	override_policy = nullptr )

Transceive APDU.

Parameters

[out]	rx	Receive buffer (response + SW)
[in,out]	rx_len	In: capacity of rx, Out: received length
	cmd	Command APDU
	cmd_len	Command APDU length
	override_policy	Optional per-call timeout/retry override (nullptr uses config values)

Returns

True if succeeded

Note

override_policy is forwarded to the underlying transceiveINF for this exchange only

transceiveINF()

bool m5::nfc::isodep::IsoDEP::transceiveINF	(	uint8_t *	rx_inf,
		uint16_t &	rx_inf_len,
		const uint8_t *	tx_inf,
		const uint16_t	tx_inf_len,
		RxInfo *	info = nullptr,
		const policy_t *	override_policy = nullptr )

Transceive INF.

Parameters

[out]	rx_inf	Receive INF buffer
[in,out]	rx_inf_len	In: capacity of rx_inf, Out: received INF length
	tx_inf	Transmit INF buffer
	tx_inf_len	Transmit INF length
[out]	info	Optional receive information (chaining/WTX)
	override_policy	Optional per-call timeout/retry override (nullptr uses config values)

Returns

True if succeeded

Note

override_policy applies to this exchange only; it does not persist and does not reset the block number
