Type4RemoteInitiator(NFCController *controller, const Span< uint8_t > &buffer)
Create a Type4RemoteInitiator.
virtual void add_iso7816_application(nfc_tech_iso7816_app_t *application)
Register an ISO7816 application to be used by the initiator.
virtual bool is_iso7816_supported() const
Retrieve whether ISO7816 applications are supported by the underlying technology. ...
virtual bool is_ndef_supported() const
Check if this instance actually supports NDEF content.
This class represents a remote NFC initiator (the local controller being in target mode)...
int nfc_err_t
Type for NFC errors.
Definition: nfc_errors.h:59
virtual nfc_err_t disconnect()
Disconnect the remote endpoint.
This class represents a NFC Controller.
Definition: NFCController.h:53
virtual ~Type4RemoteInitiator()
Type4RemoteInitiator destructor.
virtual nfc_tag_type_t nfc_tag_type() const
Retrieve the NFC tag type exposed by the controller to communicate with the initiator.
virtual nfc_err_t connect()
