With ISO-DEP I/F (e.g. ISO14443) and NFC-DEP I/F (i.e. P2P), the NCI provide such an event only when the host sends data: the event CORE_INTERFACE_ERROR_NTF (with status RF_TRANSMISSION_ERROR or RF_PROTOCOL_ERROR or RF_TIMEOUT_ERROR) is sent to the host to indicate that the controller encountered an error while sending the data to the tag.
