The present invention relates to a method for managing Bluetooth wireless communication in a Bluetooth device, and in particular, a Bluetooth device user can provide a user connection setting function to a Bluetooth device capable of point-to-point or point-to-multipoint Bluetooth wireless communication. The present invention relates to a Bluetooth wireless communication management method of a Bluetooth device for setting a list of Bluetooth devices having priority in a Bluetooth wireless communication connection and automatically setting a wireless communication connection with a corresponding Bluetooth device when the Bluetooth device is operating.

According to the recent development trend of wireless communication, PC and peripheral devices, mobile communication terminals, PC, and home appliances, which are located at a short distance, are connected to each other through a wireless network, enabling two-way real-time communication without complicated wiring. Bluetooth is emerging as an important component of wireless communication.

Therefore, the ultra short-range wireless network is established through a wireless interface formed between Bluetooth-equipped devices by attaching Bluetooth to all information devices used in homes and offices, thereby enabling free data exchange between all information devices.

The Bluetooth system provides two data access methods, synchronous connection-oriented (SCO) and asynchronous connectionless (ACL), to support multimedia data mixing voice and data. It is related to an ACL link that supports point-to-multipoint communication in a packet-switched manner, either symmetrically or asymmetrically for transmission.

A Bluetooth system that communicates through one channel on a one-to-one or one-to-N basis through such an ACL link has one of the devices participating in the communication as a master and the other devices as slaves. According to the traffic control of the (master), communication with the connected slave (slave) is established.

However, in this Bluetooth system, since only one device can maintain a communication connection to a slave in the case of 1-to-n communication, the master-side Bluetooth uses the initial inquiry scan / response process to establish a Bluetooth device within the detection range. After collecting and storing information on the connection, a connection with the corresponding Bluetooth device is established according to the user's connection request.

Accordingly, even if the device is mainly used by the user, there was an inconvenience of having to establish a connection every time.

For example, if all the devices in your office are equipped with Bluetooth and your PC's keyboard and mouse are also set up to connect via Bluetooth wireless communication, your PC will turn on your PC. The Bluetooth of the (PC) repeatedly performs a process of setting up a connection for each Bluetooth device within a detection range, collecting Bluetooth information, and terminating the connection.

The PC is in a Bluetooth wireless communication with the Bluetooth devices, but since the number of PCs that can maintain the Bluetooth wireless communication connection is limited, the PC may not be connected to the device to be used. The user may be inconvenient to select a Bluetooth communication connection with a keyboard and mouse each time the PC is used.

As another example, the number of slave bluetooths that can be connected from the master Bluetooth when the Bluetooth is installed in the home electronics is limited, so the user may repeatedly set up the connection for the Bluetooth connection even in the case of high frequency of use. There was discomfort because it should.

In addition, when the Bluetooth wireless communication connection between the Bluetooth devices is established through this process, the user does not have a means for distinguishing which device is currently connected to the Bluetooth device that is being used for communication with the Bluetooth device. In this case, a method of selecting and confirming a Bluetooth communication setting was used.

However, this method has a problem of repeatedly attempting to establish a Bluetooth wireless communication in the case of a device which has already established a Bluetooth wireless communication connection.

In order to solve the above-mentioned problems of the prior art, the present invention relates to a list of Bluetooth devices having a Bluetooth connection priority through a user connection setting function. It is an object of the present invention to automatically set a wireless communication connection so that a user of a Bluetooth device can manage a wireless communication connection with the Bluetooth devices for Bluetooth wireless communication through the Bluetooth device list.

To this end, the present invention includes a Bluetooth device list setting step of setting a slave Bluetooth device list to be automatically connected through the user connection setting function in the master Bluetooth; A Bluetooth communication connection step of attempting to establish a Bluetooth wireless communication connection with slave Bluetooths within a detection range by prioritizing slave Bluetooth in the Bluetooth device list when Bluetooth wireless communication is selected in the master Bluetooth; When the wireless communication with the slave Bluetooth is connected through the Bluetooth wireless communication connection attempt, characterized in that it comprises a Bluetooth wireless communication step for executing the Bluetooth wireless communication.

Hereinafter, with reference to the accompanying drawings the present invention will be described in detail.

According to the present invention, the slave side Bluetooth devices (hereinafter, slave) when the user Bluetooth device is operated through a user connection setting function in a master side Bluetooth device (hereinafter referred to as master Bluetooth) capable of point-to-point or point-to-multipoint Bluetooth wireless communication. Bluetooth wireless communication connection with Bluetooth).

Although not illustrated, the master Bluetooth according to an embodiment of the present invention includes a host for performing overall device-specific operations and Bluetooth wireless communication control, and a Bluetooth module for performing Bluetooth wireless communication through the host. .

As such, the Bluetooth module receives a control command of the host transmitted as an HCI data packet through an HCI (HOST CONTROL INTERFACE), which is an interface defined for transmitting and receiving data packets with the host, and transmits the processing result to the host.

In addition, the slave Bluetooth according to an embodiment of the present invention is configured to include a host and a Bluetooth module, such as the master Bluetooth, the host is for indicating the communication connection according to the Bluetooth authentication message transmitted from the host of the master Bluetooth It also includes an output device such as an LED or a speaker for sound output.

The present invention using the Bluetooth device configured as described above will be described in detail with reference to FIGS. 1 and 2.

As shown in FIG. 1, a master Bluetooth user capable of point-to-point and point-to-multipoint Bluetooth wireless communication needs to register a slave Bluetooth that requires a Bluetooth communication connection every time the master Bluetooth is operated, among the slave Bluetooths used. Select the Bluetooth wireless communication in the master Bluetooth (S1).

When the Bluetooth module of the master Bluetooth is executed according to the user's selection, the Bluetooth module searches for the slave Bluetooth equipped with all the Bluetooth modules within the Bluetooth wireless communication detection range (S2).

The Bluetooth search of the master Bluetooth executes an inquiry scan through the radio frequency transmitter / receiver in the Bluetooth module and transmits a radio frequency signal including the Bluetooth address of the slave Bluetooth transmitted in response thereto. Is done through.

When the slave Bluetooth is searched through the Bluetooth search process, the search result is transmitted to the host, and the host displays the slave Bluetooth devices searched through the display unit as a list (S3).

The user checks whether the slave Bluetooth that the user wants to connect automatically has been found by setting the connection setting function through the displayed list of detected slave Bluetooth, and the host of the master Bluetooth is determined by the user's selection signal. It is determined whether the selection (S4).

If the slave Bluetooth is selected by the user as a result of the determination, the Bluetooth address of the corresponding slave Bluetooth is registered in the list of Bluetooth devices for automatic connection (S5). If the slave Bluetooth is not selected by the user, the user sets the automatic connection. Since the slave Bluetooth to be detected is not searched, it is determined whether a registration key for directly inputting the corresponding Bluetooth address is selected (S6).

As a result of the determination, when the registration key is selected, an input window is displayed so that the user can input the Bluetooth address of the slave Bluetooth that the user wants to set up automatic connection through the display unit, and registers the Bluetooth address input by the user in the list of Bluetooth devices. If the result registration key is not selected (S7).

When the user registers a Bluetooth address to establish automatic connection in the Bluetooth device list through the Bluetooth device list registration process, the host of the master Bluetooth determines whether to select an ACL connection with the slave Bluetooth corresponding to the registered Bluetooth address by the user. Determine (S8).

As a result of the determination, if the ACL connection is selected, the ACL setting process is executed using the registered Bluetooth address, and if not, the process ends (S9).

When the master Bluetooth user sets the Bluetooth device list that is automatically connected to the host through the automatic connection setting function when the master Bluetooth operation is performed through the above process, the slave block of the Bluetooth device list through the process shown in FIG. Perform an automatic connection with Lutus.

When the master Bluetooth user selects the Bluetooth wireless communication, the host executes an inquiry scan / response process with a certain Bluetooth wireless communication range through the Bluetooth module (S10).

When the slave Bluetooth within the Bluetooth wireless communication range is searched through the inquiry scan / response process, the link control unit of the Bluetooth module transmits a search result to the host (S11).

The host detects the stored Bluetooth device list and determines whether there is a slave Bluetooth in the Bluetooth device list set in the searched slave Bluetooth list (12).

As a result of the determination, if there is a slave Bluetooth in the Bluetooth device list, the corresponding slave Bluetooth is displayed in the found slave Bluetooth list (S13), and if it is selected by the user in the displayed slave Bluetooth, it is determined whether the current ACL is set (S14).

If it is determined that the ACL is set, the current ACL is maintained (S15). If the ACL is not set, the ACL setting process with the corresponding slave Bluetooth is executed (S16).

If the ACL is set with the slave Bluetooth in the list of Bluetooth devices automatically connected by the user through this process, the Bluetooth modules of the slave Bluetooth are put in standby mode to reduce power consumption due to Bluetooth wireless communication for maintaining the ACL with the slave Bluetooth. (S17) to the mode (park mode) or low power mode (sniff mode or low-power mode).

Through this, the master Bluetooth performs Bluetooth wireless communication with the slave Bluetooth including the slave Bluetooth of the set Bluetooth device list.

During the Bluetooth wireless communication, if the master Bluetooth user wants to check the slave Bluetooth that is currently executing the Bluetooth wireless communication, the master Bluetooth user selects a specific slave Bluetooth to check from the list of Bluetooth devices or selects all slave Bluetooth.

According to the slave Bluetooth selection signal of the user, the host of the master Bluetooth generates a Bluetooth authentication message (User_Identification_Req_Msg) as shown in FIG. 3 (S20), and converts the Bluetooth authentication message into an HCI data packet (HCI_Dev_Identification_Request Command). Send to the Bluetooth module (S21).

The master Bluetooth transmitted HCI_Dev_Identification_Request Command is converted into a radio frequency signal through the baseband processor and transmitted to the Bluetooth module of the slave Bluetooth by the radio frequency transmitter / receiver.

Upon receiving this, the Bluetooth module of the slave Bluetooth transmits the reception of the received Bluetooth authentication message to the host as an HCI_Dev_Identification_Request Event (S22), and the hose of the slave Bluetooth confirms through the LED or the speaker according to the Bluetooth authentication message of the master Bluetooth. Outputs the master Bluetooth user to check the Bluetooth wireless communication connection (S23).

In addition, the slave Bluetooth generates a response message (User_Identification_Resp_Msg) for the Bluetooth authentication message received through the above process (S24), converts the generated response message into an HCI data packet (HCI_User_Identification_Reply Command) Bluetooth module of the slave Bluetooth Transfer to (S25).

When the Bluetooth module transmits the response message of the converted HCI data packet to the Bluetooth module of the master Bluetooth, the Bluetooth module generates a Command Complete Event to receive the response message from the Bluetooth module of the master Bluetooth (S26), and the generated Command Complete Event generates a response message ( The user's response to the data packet received by the host through User Idetification Resp Msg) is checked (S27).

The process of transmitting the response message of the slave Bluetooth may be omitted.
