Enum Constant Summary

Enum Constants
Enum Constant and Description
`AUTHENTICATION_ERROR` The authentication between the library and the device has failed
`BUSY` Device is Busy
`CARD_ABSENT` Connect invoked, but there's no card in the slot
`CARD_COMMUNICATION_ERROR` Transmit invoked, and no response from the card (the card is likely to have been removed during the exchange)
`CARD_MUTE` A card is present, but it is unresponsive
`CARD_POWERED_DOWN` Transmit invoked, but Disconnect has been called earlier
`CARD_REMOVED` Transmit or Disconnect invoked, but the library is aware that the card has already been removed
`COMMUNICATION_TIMEOUT` The underlying BLE device is still connected, but a CCID-level timeout has occurred (no RDR_To_PC after a PC_To_RDR)
`DEVICE_NOT_CONNECTED` The library has been called to instantiate a device (SCardReaderList object), but the provided input parameter does not refer to a connected BLE device. Or the underlying BLE device has been disconnected
`DIALOG_ERROR` The device does not answer as expected (ex: empty response to a SCardControl that is looking for the slot name)
`DUMMY_DEVICE` The number of slots in CCID_Status is 0
`ENABLE_CHARACTERISTIC_EVENTS_FAILED` The library has failed to enable the notifications or indications on a given characteristic
`INVALID_CHARACTERISTIC_SETTINGS` One of the mandatory characteristics has not the expected settings (for instance, read/write/notify flags not consistent with the implementation in the library)
`INVALID_PARAMETER` Invalid parameter
`INVALID_SERVICE_SETTINGS` One of the mandatory services has not the expected settings (for instance, bonding flags not consistent with the implementation in the library)
`MISSING_CHARACTERISTIC` One of the mandatory characteristics is missing from the device's GATT
`MISSING_SERVICE` One of the mandatory services is missing from the device's GATT
`NO_SUCH_SLOT` getReader invoked with an invalid parameter
`OTHER_ERROR` Other error
`PROTOCOL_ERROR` The format of the RDR_To_PC or CCID_Status characteristic is invalid (unsupported opcode, bad length etc)
`READ_CHARACTERISTIC_FAILED` The library has failed to read a given characteristic
`SECURE_COMMUNICATION_ABORTED` The device has reported a secure communication on its side and is closing the communication
`SECURE_COMMUNICATION_ERROR` Wrong CMAC or frame decipher failed
`UNSUPPORTED_PRIMARY_SERVICE` The device's primary service is not supported by the library
`WRITE_CHARACTERISTIC_FAILED` The library has failed to write a given characteristic
