Abstract

The invention provides CCID equipment with a Bluetooth interface and a working method of the CCID equipment. The working method comprises the following steps: detecting whether a communication mode type is changed or not; if not, returning CCID instruction responding data back to an upper computer according to the communication mode type and data in a second buffering region; if so, resetting a Bluetooth module and returning the CCID instruction responding data back to the upper computer; after acquiring the CCID instruction data by a USB module, determining whether the type of the CCID instruction data is matched with the communication mode type or not; if so, transmitting serial port instruction data to the Bluetooth interface according to the type of the CCID instruction data; otherwise, setting a matched communication mode type according to the type of the CCID instruction data and storing the serial port instruction data into a first buffering region; and after acquiring the serial port instruction responding data by a Bluetooth module, storing the serial port instruction responding data to the second buffering region.

Description

technical field [0001] The invention relates to the communication field, in particular to a CCID device with a bluetooth interface and a working method thereof. Background technique [0002] The CCID device is a chip / smart card interface device. The CCID device is connected to the host or other embedded hosts through the USB interface for data communication in accordance with the CCID protocol standard. At the same time, the device communicates with the smart card through the interface in compliance with the 7816 standard protocol. "Bluetooth" is a short-distance wireless connection technology that is used worldwide. [0003] In the prior art, a CCID device can only be connected to a host or other embedded hosts through a USB interface, which limits the development and application of the CCID device. Contents of the invention [0004] The invention solves the defect of limited development and application of CCID equipment in the prior art. [0005] Technical scheme of th...
