Description

{Apparatus for adapter using a bluetooth technology and Operating method for the same}

The present invention relates to an adapter device and an adapter driving method using a Bluetooth technology.

More specifically, a pair of adapter devices using Bluetooth technology are connected to parallel ports of two electronic devices that perform data transmission or reception, respectively, and data output from any one electronic device is connected to the corresponding electronic device. The present invention relates to an adapter device and an adapter driving method using a Bluetooth technology for transmitting to an adapter device connected to another electronic device through a Bluetooth device.

In recent years, with the development of wireless data communication technology, the Infrared Data Association (IrDA) has established a communication standard for sending and receiving data using infrared rays in the electromagnetic period.In addition, computers, printers, Electronic products such as portable communication devices are increasing.

IrDA is a technology for transmitting data in the infrared without a cable. Since the wireless infrared IrDA communication port can transmit and receive 11,250 bits of digital information per second, which is comparable to a simple LAN, it can be used for documents and multimedia. There is no problem in transmitting information, the maximum data rate is 4Mbps, and the maximum transmission distance is 1m.

Thus, when using a notebook PC with IrDA communication, users can spread the notebook to the infrared port of the desktop PC and click the Send Data button to send the information wherever they want.

As described above, wireless data communication using infrared rays has the advantage of performing data communication without connecting cables between electronic devices performing data communication. However, a shield that does not pass infrared rays is blocked for wireless data communication. In addition, the distance between the devices should be located close to each other, as well as the inconvenience of having to face each other in a straight line distance.In addition, since there are many influences on the surrounding environment, there is a high probability of error occurring during wireless data communication. There was this.

In addition, wireless data communication using infrared rays is not suitable for large-capacity wireless data communication, but also has a slow data transmission rate.

As a result, there has been a great deal of research around the world to develop new technologies to overcome the shortcomings of wireless data communication using infrared light. In recent years, Ericsson in Sweden, IBM in the US, Intel in Finland, Nokia in Finland, and Japan in Japan A common protocol for wireless data communication called 'Bluetooth', which is the development code name of the wireless data communication standard under development by Toshiba, has been prepared. As a result of the research and development, Bluetooth has been applied to actual products.

Bluetooth is a technology that enables two-way real-time communication that connects computers and peripherals, mobile terminals, computers, and home appliances that are located in a short distance to each other without a complicated cable, and through a wireless network. It allows data to be transported to where it is not, supports all directions, not just in one direction, and supports both isochronous and asynchronous services for easy integration of TCP / IP in networking.

In addition, the maximum communication distance covers a range of 10m (increasing the transmission power can be extended to 100m), and can be performed by two-way real-time communication without complicated cables in the office or apartment indoors and wireless network. It will be upgraded to 1Mbps to 2Mbps or more in the future.

In this case, the above-mentioned 1Mbps is a transmission rate that can be realized at a relatively easy and low cost by using an industrial scientific medical (ISM) band of 2.4G) freely available to users without a license.

In addition, Bluetooth adopts CVSD (Continuous Variable Slope Delta Modulation), which is a voice encoding method, which can be used not only for text data transmission but also for voice transmission, and also uses encryption technology to maintain communication secrets.

In addition, the biggest feature of Bluetooth compared to the above-described IrDA method is that the portable communication device can communicate with other communication devices in a bag or a pocket.

In other words, the difference between the IrDA method and the Bluetooth method is described as an example.In the Bluetooth method, image data recorded with a digital camera can be transmitted without any cumbersome procedures such as a cable connection with a PC or a mobile phone at any state within a certain distance. In the case of IrDA method, data communication without cable connection is the same as that of Bluetooth, but communication is not possible when a shield that does not pass infrared rays is blocked.

However, in the above-described Bluetooth method, in order to apply the Bluetooth method to various electronic devices, an expensive cost is required, unlike the IrDA method, and a separate adapter using Bluetooth technology in addition to the method of directly embedding the Bluetooth method into the electronic device at present. Since the device is not yet developed and is not compatible with existing electronic devices, users have to purchase and use electronic devices with Bluetooth technology.

An object of the present invention is to solve the above-mentioned problems, after separately manufacturing a pair of adapter device to which the Bluetooth technology is applied, without having to apply the Bluetooth technology directly in the electronic device to perform data transmission or reception, a pair of adapters Connect the device to the parallel port of two electronic devices that perform data transmission or reception, respectively, and connect the data output from one electronic device to another electronic device via Bluetooth through an adapter device connected to the electronic device. An object of the present invention is to provide an adapter device and an adapter driving method using Bluetooth technology for transmitting to an adapter device.

Next, an embodiment of the adapter driving method using the Bluetooth technology according to the present invention configured as described above will be described in detail with reference to FIGS. 3 to 11, and is connected to the PC 200 in the use state of FIG. 2 for convenience. It demonstrates on the basis of the drive of the adapter apparatus 100 which was made.

3 to 11 are flowcharts showing in detail the operation of the adapter driving method using the Bluetooth technology according to the present invention.

First, the central processing unit 120 of the adapter device 100 initializes the system state of the adapter device 100 (S100). In other words, the initialization of the following system states is performed.

Jump to processor start-up code

-Initialize memory

-Initialize the interrupt vector table

-Initialize process table

Initialize internal data structure

System clock initialization

-Initialize input / output device

Create Channel A Input / Output Tasks

Create Channel B Input / Output Tasks

-Interrupt enabled

As such, after initializing the system state of the adapter device 100 through the above-described process (S100), the central processing unit 120 of the adapter device 100 processes the transmission or reception data according to the Bluetooth technology inputted from the counterpart electronic device. Create a system task for (S200). In other words, create a series of tasks as follows:

Create application task

-Adjust task priority down

Infinite loop (switches to a dummy task), where the dummy task periodically performs a watchdog function on key variables

Transfer of control to the main (application) task by the scheduler

-Take control if there is no task to perform at any point

Subsequently, the central processing unit 120 of the adapter device 100 performs input / output processing of data for each of A and B channels using Bluetooth technology according to the task generated in the above-described process (S200), and at the same time, A and B each. The main (application) task of the adapter device for input / output processing of data for each channel is performed (S300 to S700).

In addition, the above-described processes (S300 to S700) are repeated indefinitely until the adapter device 100 is released from the electronic device by the user (S800).

At this time, in the above-described processes (S300 to S600), the data of the channel A is data to be transmitted from one adapter device to another adapter device, the data of the channel B is data received from another adapter device.

Meanwhile, when the input processing for the channel A data of the above-described process S300 is described in more detail with reference to FIG. 4, the central processing unit 120 receives data from an electronic device to which the adapter device 100 is connected. After initializing the input channel (input data structure) (S310), the adapter device 100 determines whether the overflow occurs in the buffer by checking the input data input from the connected electronic device (S320).

If the overflow of the buffer does not occur as a result of the determination, it is determined whether there is reception data output from the electronic device (S330), and if the reception data output from the electronic device exists, the received data is stored in the input buffer (S340). .

After storing the received data in the input buffer, it is determined whether a data request is performed in the application (S350). When the data request is performed in the application, the data is transmitted from the input buffer to the application data buffer by the corresponding number of bytes. (S360).

When the transfer of data from the input buffer to the application data buffer is terminated, control authority is transferred to the application task (S370), and control authority is restored again by scheduling (S380).

In addition, when the output processing for the channel A data of the above-described process (S400) will be described in more detail with reference to FIG. 5, the central processing unit 120 receives the data received from the electronic device to which the adapter device 100 is connected. The output channel (output data structure) to be output is initialized (S410).

The standby state is maintained until there is an output request from the application task (S420), and it is determined whether the output of data received from the electronic device from the application task is requested in the standby state (S430).

As a result of the determination, when the output of the data received from the electronic device is requested from the application task, the data is transmitted from the output buffer to the application data buffer by the corresponding number of bytes (S440). At this time, if there is no extra data in the output buffer, the data transfer to the application data buffer is terminated.

When the transmission of data from the output buffer to the application data buffer ends, the corresponding data is transmitted to the adapter device 100A connected to the counterpart electronic device through the Bluetooth method (S450).

When the transmission of the corresponding data to the adapter device 100A connected to the counterpart electronic device through the Bluetooth method is terminated, control authority is transferred to the application task (S460), and control authority is restored again by scheduling (S470).

Now, in addition to the input / output processing for the channel A data of the above-described process (S300, S400), the input processing for the channel B data of the above-described process (S500) will be described in more detail with reference to FIG. In operation 120, an input channel (input data structure) for receiving data from the adapter device 100A connected to the counterpart electronic device is initialized (S510), and the input data input from the adapter device 100A connected to the counterpart electronic device is input. In operation S520, it is determined whether an overflow occurs in the buffer.

If it is determined that the overflow of the buffer does not occur, it is determined whether there is reception data output from the counterpart electronic device (S530), and if there is the reception data output from the counterpart electronic device, the received data is stored in the input buffer ( S540).

After storing the received data in the input buffer, it is determined whether a data request is performed in the application (S550). When the data request is performed in the application, the data is transmitted from the input buffer to the application data buffer by the corresponding number of bytes. (S560).

When the transfer of data from the input buffer to the application data buffer is terminated, control authority is transferred to the application task (S570), and control authority is restored again by scheduling (S580).

In addition, when the output processing for the channel B data of the above-described process (S600) will be described in more detail with reference to FIG. 7, the central processing unit 120 outputs the data received from the adapter device 100A connected to the counterpart electronic device. The output channel (output data structure) is initialized (S610).

The standby state is maintained until there is an output request from the application task (S620), and it is determined whether the output of data received from the electronic device from the application task is requested in the standby state (S630).

As a result of the determination, when the output of the data received from the electronic device is requested from the application task, the data is transmitted from the output buffer to the application data buffer by the corresponding number of bytes (S640). At this time, if there is no extra data in the output buffer, the data transfer to the application data buffer is terminated.

When the transmission of data from the output buffer to the application data buffer is completed, the adapter device 100 outputs the data received through the Bluetooth method to the connected electronic device (S650).

When the output of the data received from the adapter device 100A connected to the counterpart electronic device through the Bluetooth method to the electronic device connected to the adapter device is terminated, transfer control authority to the application task (S660), and again by scheduling Restore control authority (S670).

Meanwhile, when the main (application) task performing process of the above-described process (S700) is described in more detail with reference to FIGS. 8 to 11, first, an adapter device 100 (100A) connected to a pair of electronic devices is described. Open the input / output channels of A or B (S710), initialize the Bluetooth memory manager, create a Bluetooth transmit or receive task, initialize the Bluetooth module interface (HCI), initialize the link level protocol (L2CAP), and link level protocol (L2CAP) layer. Initializes a main (application) task such as upper layer protocol (PRNTP) initialization that can be called (S720).

In addition, the controller 100 generates and drives a task for inspecting the state of the electronic device to which the adapter device 100 or 100A is connected (S730), until the driving of the adapter device 100 or 100A connected to the electronic device is stopped. After step S710 is repeated indefinitely (S740).

When the above-described step (S730) is described as an example of a printer connected to the adapter device (100A), after generating a task for checking the state of the electronic device, the state of the printer connected to the adapter device (100A) 1 Read every second. If an error occurs, the LED alarms the occurrence of a fault and returns to the normal state after the error action.

At this time, the Bluetooth transmission or reception task generation step of the above-described step (S720) is performed as follows (see Fig. 9).

That is, the Bluetooth memory manager is initialized by allocating a memory buffer pool and initializing a queue structure for memory management (S721), and generating a task used for Bluetooth transmission or reception (S722).

Then, initialize the data structure, send a reset command to the Bluetooth module, send a Bluetooth buffer size query (command) command, adjust the flow control parameters to fit the module buffer size to initialize the Bluetooth module interface (S723), initialize the data structure, The link level protocol is initialized by checking its Bluetooth module address and registering a higher layer protocol for protocol multiplexing (S724).

In addition, by initializing a data structure, specifying a callback function that can be called by the link level protocol layer, and registering its own protocol ID in the link level protocol layer, an upper layer protocol that can be called by the link level protocol layer is initialized (S725). ).

In addition, in step S722 described above, the Bluetooth reception task performs the following steps (see FIG. 10).

That is, the adapter device 100 determines whether there is data received from the connected electronic device (S7221), and if the received data exists, configures a Bluetooth module interface packet (S7222).

Then, it is determined whether the configuration work of the Bluetooth module interface packet is finished (S7223). When the configuration work of the Bluetooth module interface packet is finished, it is determined whether the corresponding Bluetooth module interface packet is a valid packet (S7224).

As a result, if the Bluetooth module interface packet is valid, it is determined whether the packet is an event packet or an ACL packet (S7225).

If it is determined that the corresponding Bluetooth module interface packet is an event packet, event packet processing is performed (S7226). If the corresponding Bluetooth module interface packet is an ACL packet, the ACL packet processing is performed (S7227). .

At this time, the ACL packet processing of the above-described step S7227 is performed as follows (see Fig. 11).

That is, it is determined whether the ACL packet is a valid link level protocol packet (S7227a). If the ACL packet is a valid link level protocol packet, it is determined whether the ACL packet is a signal packet or a data packet (S7227b).

As a result of the determination, if the ACL packet which is a valid link level protocol packet is a signal packet, signal packet processing is performed (S7227c). If the ACL packet is a data packet, data packet processing is performed (S7227d).

For example, referring to the use state illustrated in FIG. 2, the above-described signal packet process performs a series of operations as follows.

When the connection request is received, the request is sent to the upper layer (PRNTP).

The upper layer forwards the connection response to the link level protocol (L2CAP).

-When a request for configuration information is received, the request is sent to the upper layer after an appropriate state check

-Upper layer forwards configuration information response to link level protocol

-When the release request is received, the data request is sent to the upper layer.

The upper layer forwards the release response to the link level protocol.

The data packet processing described above performs a series of operations as follows.

-All data packets are forwarded to upper layer after inspection

-In case of print start command, it sends response to link level protocol and prepares for printing.

-For print data, send the data to the printer after checking the packet sequence number and the printer status.

In the case of a print end command, the entire size of the printed data is recorded in the response packet and transmitted to the link level protocol.
