Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, the present invention realizes the control to the embedded Bluetooth terminal with blue tooth interface by being connected 103 setting up wireless bluetooth between control appliance 101 and the Bluetooth terminal 102.Since adopted wireless connections, so it is its connection is flexible, low to the environmental requirement of embedded Bluetooth terminal surrounding.
As shown in Figure 2, be that control appliance utilizes bluetooth to connect the flow process that Bluetooth terminal is controlled.In the present embodiment, control appliance refers to PC (Personal Computer, personal computer) or PDA (PersonalDigital Assistant, personal digital assistant), in other embodiments, control appliance also can be other equipment with blue tooth interface, remote controller for example, mobile phone etc.The reciprocal process of PC/PDA and Bluetooth terminal is:
Step 201:PC/PDA sends the bluetooth connection request to Bluetooth terminal;
Step 202: Bluetooth terminal is received the bluetooth connection request, and this bluetooth connection request is verified, if the verification passes, sends bluetooth to PC/PDA and connects and confirm, sets up bluetooth between PC/PDA and the Bluetooth terminal and is connected; Then, PC/PDA starts the SPP service, sets up virtual message channel with Bluetooth terminal;
After setting up virtual message channel, PC/PDA can also be provided with the relevant port parameter of virtual serial port (being virtual message channel port) by the Telnet agreement.
Step 203:PC/PDA instructs to the Bluetooth terminal transmit operation by virtual SPP message channel;
PC/PDA can send to Bluetooth terminal with operational order by virtual SPP message channel by the Telnet agreement.
Step 204: Bluetooth terminal is resolved, is handled by the bluetooth analysis program after receiving operational order, uses by control then corresponding result is sent to PC/PDA, and result also is to send by virtual SPP message channel;
A kind of controlling mechanism that refers on the bluetooth protocol repertory is used in above-mentioned control, should be used for being implemented in the operational order of control appliance to Bluetooth terminal by control.The bluetooth analysis program can adopt the Shell program.When needing, can repeating step 203～204, finish transmission, execution and the feedback of other operational order.In addition, if desired, for example the control personnel need read the data of Bluetooth terminal, result can be presented on the screen of PC/PDA, and the demonstration of result can be finished by " hyper terminal " that operate on the PC/PDA.
Step 205: after all operational orders all sent and are finished, PC/PDA sent to Bluetooth terminal and disconnects the bluetooth connection request;
PC/PDA can require to disconnect bluetooth and connect by sending Disconnect message to Bluetooth terminal.Disconnect message is a kind of message that is used for " disconnection " by developer's definition.
Step 206: after Bluetooth terminal is received the disconnection bluetooth connection request of PC/PDA transmission, send the disconnection bluetooth to PC/PDA and connect acknowledge message, finish and nullify the SPP message channel, disconnection PC/PDA is connected with the bluetooth of Bluetooth terminal.
Wherein, in control appliance inside, the process of transmitting of operational order comprises as shown in Figure 3:
The main frame of control appliance (being first main frame among Fig. 3) sends to bluetooth protocol repertory by Telnet agreement (" hyper terminal " program of for example using Windows to carry) with operational order, bluetooth protocol repertory is converted into corresponding data with operational order, then by UART (Universal AsynchronousReceiver/Transmitter, universal asynchronous reception/dispensing device) or USB (Universal Serial Bus, USB) send to first Bluetooth chip, first Bluetooth chip sends the data to the Bluetooth terminal of far-end again by radio-frequency antenna.
In Bluetooth terminal inside, receive operational order and handle, the process that again result is sent to control appliance comprises as shown in Figure 4:
The operational order data that Bluetooth terminal sends by the second Bluetooth chip receiving control apparatus, the operational order data are sent to the main frame (being second main frame among Fig. 4) of Bluetooth terminal through UART or USB, and the main frame of Bluetooth terminal resolves message, handle by command analysis program Shell; After disposing, control program of the host computer invokes of Bluetooth terminal, processing result information is converted into corresponding data and sends to bluetooth protocol repertory, send to second Bluetooth chip by bluetooth protocol repertory through UART or USB, second Bluetooth chip sends to control appliance by radio-frequency antenna with corresponding data again.After control appliance receives result, result is exported on screen by " hyper terminal " that operate on the control appliance.
Below be an application example of the present invention,, on-vehicle Bluetooth equipment controlled being main frame with PC (" hyper terminal " program of using Windows to carry) with in the example.
This example needs following step:
Step 1:PC sends pairing request to on-vehicle Bluetooth equipment, and on-vehicle Bluetooth is set up bluetooth through checking with PC and is connected.PC startup SPP serves also and on-vehicle Bluetooth equipment is set up a virtual message channel.After succeeding in registration, message channel can be provided with the relevant port parameter of virtual serial port by Windows " hyper terminal " program.
Step 2:PC sends to operational order the on-vehicle Bluetooth equipment of far-end by virtual SPP message channel by Telnet agreement (" hyper terminal " program of using Windows to carry).The PC inside story is handled as shown in Figure 3." hyper terminal " program that first main frame uses Windows to carry sends to bluetooth protocol repertory with operational order, bluetooth protocol repertory is corresponding data with message transformation, give first Bluetooth chip by UART or USB then, first Bluetooth chip sends to message by radio-frequency antenna the on-vehicle Bluetooth equipment of far-end again.
Step 3: on-vehicle Bluetooth equipment is received the message that far-end PC sends, and message is handled, and then result is sent to PC, by " hyper terminal " that operate on the PC result is exported on screen.On-vehicle Bluetooth device interior Message Processing as shown in Figure 4.After on-vehicle Bluetooth equipment receives the message of far-end PC transmission by second Bluetooth chip, give second main frame through UART or USB with message; Second main frame resolves message, handle by command analysis program Shell; Control program of second host computer invokes is corresponding data with the result message transformation then, issues second Bluetooth chip by bluetooth protocol repertory through UART or USB, and second Bluetooth chip sends to message by radio-frequency antenna the PC of far-end again.
Step 4: repeating step 2, step 3, to on-vehicle Bluetooth equipment transmit operation instruction, Bluetooth terminal is resolved instruction result is shown on the screen of PC by PC.
Step 5:PC sends Disconnect message to on-vehicle Bluetooth equipment, nullifies the SPP message channel, disconnects bluetooth and connects.
As seen, above-mentioned example has succinctly been realized the control to on-vehicle Bluetooth equipment easily, effectively avoided the defective and the deficiency that exist in the prior art scheme, guaranteed, thereby provide a kind of efficient, feasible control method for embedded device the control rapidly and efficiently of various embedded devices.
The above embodiment is the preferred embodiment that proves absolutely that the present invention lifts, and protection scope of the present invention is not limited thereto.Being equal to that those skilled in the art are done on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
