Formulated by telecommunications giant Ericsson in 1994, be the alternative solution as RS232 data wires at that time, bluetooth can connect many
Individual equipment, overcomes the problem of data syn-chronization.
Bluetooth technology is widely used and vehicle carried video system, and Handsfree, phone directory work(are realized by Bluetooth chip
Energy, the control of resume function, redialing function, music, broadcast information such as show at the function.There is work(in existing on-vehicle Bluetooth chip
Can imperfection, hardware cost height, the problems such as exploitation is difficult.
The content of the invention
It is an object of the invention to provide a kind of good stability, the multifunction blue tooth chip system of low cost.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of multifunction blue tooth chip system, including Bluetooth chip, Diver control units and application of function unit；
The Bluetooth chip, using peace richness NF2301 chips, hardware supported is provided for application of function unit；
The Diver control units, data transfer is carried out by UART communications and Bluetooth chip, and control Bluetooth chip receives
It is required that and return to corresponding information, realize the correlation function of application of function unit；
The application of function unit includes
HSP modules, for providing the required basic function that communicated between equipment and earphone；
HFP modules, for increasing expanded function on the basis of HSP, mobile electricity is controlled from fixed on-vehicle hands-free device
Words；
OPP modules, for providing phone directory receive capabilities；
SPP modules, for creating the agreement that serial ports carries out data transmission between bluetooth equipment；
DUN modules, for providing connection internet function, bluetooth cellular phone is used as modulation /demodulation during connection internet
Device；
A2DP modules, for transmitting stereo audio signal；
AVRCP modules, for sent from controllers such as stereophones to target devices such as vehicle carried video equipment it is next it is bent,
The control command such as pause or broadcasting；
PBAP modules, request phone directory transmitting function is realized for bluetooth equipment；
MAP module, for realizing the short message function of exchange between bluetooth equipment.
Beneficial effects of the present invention：The multifunction blue tooth chip system that the present invention is provided, using gathering multi -function in integral whole
NF2301 chips, all Bluetooth functions needed for realizing on present vehicle audio reduce the usage amount of chip, reduce
Hardware cost；Simultaneously using the development scheme of layering, independent Diver control units are responsible for the data with NF2301 chips
Exchange, as long as application of function unit realizes the operational requirements of user's customization, reduce the development difficulty of module, add and be
The stability of system, while when user's customization changes, reducing the changing range of system so that system has one well
Continuity.
