Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the Bluetooth protocol model.
Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as structural representation of the present invention.
The present invention is a kind of blue-tooth device based on portable mobile apparatus, comprise bluetooth module and the single-chip microcomputer that is connected with bluetooth module (MCU) module, described bluetooth module also comprises voice gateways (the Audio Gateway that can switch mutually, AG) module and HCI (Host Control Interface, HCI) module, the voice gateways module is connected respectively with one-chip computer module with the HCI module.Described one-chip computer module by the UART Universal Asynchronous Receiver Transmitter interface (Universal Asynchronous Receiver/Transmitter, UART) or Serial Peripheral Interface (Serial Peripheral Interface SPI) is connected with bluetooth module.
Adopt the reason of AG module and HCI module to be that speech data is different with general data:
The data volume of speech data is few, but the real-time requirement is very high, need not retransmission mechanism;
The data volume of general data is bigger, but real-time is less demanding, can adopt retransmission mechanism.
Therefore based on the difference of two kinds of data characteristics, adopt disparate modules to handle respectively, adopt the AG resume module, adopt the HCI resume module for general data for speech data to these two kinds of data.
Wherein blue-tooth device is connected with PC by USB, described PC comprises memory and central processing unit, described central processing unit is connected by bus with memory, central processing unit is connected with the bluetooth module of blue-tooth device by USB, central processing unit is by low pin count (Low Pin Count, LPC) bus is connected with the one-chip computer module of blue-tooth device, switch use HCI module by one-chip computer module control bluetooth module, central processing unit is the data in the memory, send to by USB in the bluetooth module of blue-tooth device, and by the emission of HCI module.
At common PC interface, this moment, CPU was by the LPC interface, notice MCU (8 51 common single-chip microcomputers), MCU is again by UART or SPI mouth notice bluetooth module, bluetooth is operated in the HCI pattern, and this moment, bluetooth was similar to common computer bluetooth module, and bluetooth module only provides the carrier of hardware, the bluetooth applications agreement all runs in the operating system, realizes the application of PC bluetooth.
Blue-tooth device also comprises communication module, and be connected with the PC that is provided with central processing unit by USB, described central processing unit is connected by USB with communication module, central processing unit is connected with the bluetooth module of blue-tooth device by USB, central processing unit is connected with the one-chip computer module of blue-tooth device by the low pin count bus, switch use voice gateways module by one-chip computer module control bluetooth module, communication module is connected by 232 serial ports with bluetooth module, central processing unit control communication module, speech data is sent to the voice gateways module, and by the emission of voice gateways module.
