Abstract
A device and a method for programming the read/writeable memory of the RFID circuitry by communications between either RF antenna (12) or bus communications port controller interface (4) or both. In a peripheral device (1), an EEPROM (6), bus communications controller interface (4), NFC interface (8), antenna (12), and logic controller (10) operate to receive and transmit configuration and calibration data between a Bluetooth circuit (40) and an external device (22). The dual interfaced EEPROM (2) shares or partitions its EEPROM (6) between the Bluetooth circuit (40) and the external device (22).
Claims20
A device comprising:
- a memory comprising two interfaces wherein a first interface is a passive near field communication (NFC) interface and a second interface is a data interface;
- an NFC antenna, connected to said passive NFC interface, for communicating NFC signals with a first external device;
- and
- a microprocessor based circuit in data communication with said second interface.
A method of simply pairing a wireless personal area network enabled peripheral device with a personal area network enabled device, said method of simply pairing comprising:
- communicating an NFC communication between a passive NFC interface of said wireless personal area network enabled peripheral device and said personal area network enabled device, said NFC communication comprises authentication data;
- storing, using a first interface associated with a dual interfaced memory device within said wireless personal area network enabled peripheral device, first authentication data from said authentication data;
- retrieving, using a second interface associated with said dual interfaced memory device, said first authentication data;
- using said retrieved first authentication data, by a microprocessor based circuit within said wireless personal area network enabled peripheral device, for configuring a personal area network communication with said personal area network enabled device.
A wireless personal area network enabled peripheral device comprising:
- a passive NFC circuit for communicating NFC signals;
- an EEPROM;
- an NFC interface, between said EEPROM and said passive NFC circuit, said NFC interface communicates authentication data received by said passive NFC circuit and stores said authentication data in said EEPROM;
- a microprocessor based circuit for communicating with an external device using a personal area network protocol;
- a communications controller interface between said microprocessor based circuit and said EEPROM, said communications controller interface being for providing said authentication data to said microprocessor based circuit.
