Communication Method and Apparatus for NFC Device and NFC Device
Abstract:
A communication method and apparatus for a near field communication (NFC) device and the NFC device, where the method includes determining a radio frequency (RF) protocol supported by at least one discovered target NFC device; and selecting, according to an RF protocol level or an RF protocol priority, an RF protocol for performing NFC from the RF protocol supported by the at least one target NFC device so as to perform communication with a target NFC device corresponding to the RF protocol determined by selection. The communication method and apparatus provided in the embodiments of the present invention solve a problem that a probability of finding a target NFC device matched with an NFC controller (NFCC) chip function on a local NFC device is low and a problem that device host (DH) resource consumption and power consumption incurred thereof are high.
