Method Detail

prepareAndSendGetParameterCommand

void prepareAndSendGetParameterCommand(byte paramid)
                                       throws HCIException,
                                              javacard.framework.SystemException

This non-blocking method builds the HCI command ANY_GET_PARAMETER for the indicated information and sends it to the Contactless Reader Gate of the CLF. The prepareAndSendGetParameterCommand method should only be called when the CLF has successfully discovered a card in the field, i.e. after reception of the HCI event EVT_TARGET_DISCOVERED, otherwise the received data will be meaningless.

Parameters:

paramid - shall be one of the PARAM_* values defined in this interface

Throws:

HCIException - with the following reason code:

• HCI_CURRENTLY_DISABLED if the HCI interface was disabled
• HCI_FRAGMENTED_MESSAGE_ONGOING if the Contactless Framework is still receiving a fragmented HCI Message
• HCI_RESOURCES_NOT_AVAILABLE if the contactless framework does not have enough resources to process the command

javacard.framework.SystemException - with the following reason code:

• ILLEGAL_VALUE
  • if the paramID does not match with the predefined values

prepareAndSendWriteXchgDataCommand

void prepareAndSendWriteXchgDataCommand(byte timeout,
                                        byte[] data,
                                        short offset,
                                        short len)
                                        throws HCIException,
                                               java.lang.NullPointerException,
                                               java.lang.ArrayIndexOutOfBoundsException,
                                               javacard.framework.SystemException

This non-blocking method builds the HCI command WR_XCHG_DATA with the data passed in the parameter data and sends it to the Contactless Reader Gate of the CLF. The response data from the CLF will be transferred to the UICC with the event ReaderListener.EVENT_WRITE_EXCHANGE_DATA_RESPONSE.

Parameters:

timeout - value according to TS 102 622, or -1 if no timeout value is given

data - byte array holding the data to send to the CLF

offset - into the byte array indicating the start of the data to send to the CLF

len - overall length of data that will be send to the CLF

Throws:

HCIException - with the following reason code:

• HCI_CURRENTLY_DISABLED if the HCI interface was disabled
• HCI_FRAGMENTED_MESSAGE_ONGOING if the Contactless Framework is still receiving a fragmented HCI Message
• HCI_RESOURCES_NOT_AVAILABLE if the contactless framework does not have enough resources to process the command

java.lang.NullPointerException - if data is null

java.lang.ArrayIndexOutOfBoundsException - if operation would cause access of data outside array bounds.

javacard.framework.SystemException - with the following reason code:

• ILLEGAL_VALUE if the timeout value does not match with the predefined values

restartReaderModeProcedure

void restartReaderModeProcedure()
                                throws HCIException

This method sends first the HCI event EVT_END_OPERATION and then the HCI event EVT_READER_REQUESTED. This method is intended to recover from the following error states:

reception of RESP_ANY_E_TIMEOUT

reception of RESP_WR_RF_ERROR

reception of EVT_TARGET_DISCOVERED with a MULTIPLE_TARGET_STATUS

Throws:

HCIException - with the following reason code:

• HCI_CURRENTLY_DISABLED if the HCI interface was disable
• HCI_CONDITIONS_NOT_SATISFIED if the Applet is not ACTIVATED
