And a display unit (display) 9 for displaying various information to the user, and an operation unit 10 for inputting an instruction from the user. Although not particularly limited, the Bluetooth terminal having such a configuration can be provided in a mobile phone or the like.

In addition to the PIN information, the memory 4 stores unique ID (Bluetooth address) information, various lists described in detail below, and the like. Here, the PIN information is information including numbers, symbols, characters, and the like, and the authentication slave determines whether the Bluetooth terminal (authentication master) requesting connection is a Bluetooth terminal to which connection is to be permitted. It is used as a kind of password for password authentication.

FIG. 2 is a diagram showing the data structure of the device list L1 stored in the memory 4.

As shown in FIG. 2, the device list L1
Is composed of an ID of a device expected to be connected to the Bluetooth terminal according to the present embodiment in advance, and a corresponding profile type, nickname, device icon file name, and position information. Here, the device that is expected to be connected to the Bluetooth terminal according to the present embodiment in advance is, for example, a device equipped with a Bluetooth terminal in the home when the Bluetooth terminal according to the present embodiment is used at home. When used in an office, the device is equipped with a Bluetooth terminal in the office. Therefore, when the Bluetooth terminal according to the present embodiment is used at home, a wireless network system is constructed by the Bluetooth terminal and another Bluetooth terminal at home, and the Bluetooth terminal according to the present embodiment is used. When the Bluetooth terminal is used in an office, a wireless network system is constructed by the Bluetooth terminal and another Bluetooth terminal in the office.

The “ID” is an address (Bluetooth address) unique to each Bluetooth terminal, and cannot be changed by the user. further,
The “profile type” is the type of the device provided with the Bluetooth terminal, and 13 types of profiles are currently defined in the Bluetooth standard.

The “nickname” is an arbitrary name given to each device that is expected to be connected to the Bluetooth terminal according to the present embodiment in advance. The “device icon file” is a design file of icons indicating each device, and such an icon file is also stored in the memory 4. In this specification, a nickname and an icon may be referred to as identification information. further,
“Position information” is information indicating an installation location of each device that is expected to be connected to the Bluetooth terminal according to the present embodiment in advance.

The device list L1 having such a data structure is the device list L1 stored in the program memory 6.
It can be created by executing one editing program.

FIG. 3 is a flowchart showing a process for creating the device list L1.

First, when the user instructs to edit the device list L1 via the operation unit 10, the device control unit 1 executes another standby Bluetooth device based on the editing program for the device list L1 stored in the program memory 6. An inquiry is made to the terminal (Step S1). The Bluetooth terminal that has received the inquiry transmits its own ID and profile type to the Bluetooth terminal according to the present embodiment that has made the inquiry (step S2). As a result, the Bluetooth terminal according to the present embodiment can collect the IDs and profile types of connectable Bluetooth terminals.

When the IDs and profile types of the connectable Bluetooth terminals are collected in this way, the device control unit 1 uses the collected IDs and profile types to generate a nickname, The display unit 9 displays the device list L1 in which the device icon file name and the position information are blank (step S3). Then, when the user inputs the nickname, device icon file name, and position information corresponding to each ID via the operation unit 10 (step S4), the device list L1 is completed. In this case, the user does not need to input all of the blank nickname, device icon file name, and position information, and may input the nickname or position information only in some of the blanks.

Here, the input of the nickname is performed by the user inputting characters through the operation unit 10. The input of the device icon file name is performed not only by the user directly inputting the file name via the operation unit 10, but also by selecting the icon file name stored in the memory 4.

On the other hand, the input of the position information is performed as follows.

First, when the user instructs input of position information via the operation unit 10, the device control unit 1 executes a position information input program stored in the program memory 6. The location information input program is provided with a floor plan creation function, and the user first uses this function to create a floor plan where the Bluetooth terminal according to the present embodiment is used. For example, when the Bluetooth terminal according to this embodiment is used in a home, a floor plan of the house is created, and when the Bluetooth terminal is used in an office, a floor plan of the office is created. When the floor plan is completed in this way, the user next writes the installation location of each Bluetooth terminal whose ID is listed in the device list L1 in the floor plan. As a result, the icons of the respective devices are displayed at the installation locations on the floor plan. still,
Changing the position information can be performed by dragging the icon of the change target device displayed on the floor plan to the change position. In this way, location information is generated for each Bluetooth terminal whose ID is listed in the device list L1.

The device list L1 generated as described above
Is stored in the memory 4, and when the contents are to be updated, the contents can be updated by executing the editing program of the device list L1 stored in the program memory 6 again.

When the editing program for the device list L1 is executed again, the IDs and profile types of the connectable Bluetooth terminals are collected in steps S1 and S2, and the newly detected Bluetooth terminal is added to the device list L1. In addition, the user can input a nickname, device icon file name and position information which are still blank, and can change the already written nickname, device icon file name and position information.

FIG. 4 is a diagram showing the data structure of the selection list L2 stored in the memory 4.

As shown in FIG. 4, the selection list L2
Is composed of a profile type, a flag corresponding to the profile type, and a profile icon file name. Here, the “flag” is 1-bit data, and when this is “1”, it means that the corresponding profile type is in the selected state, and when this is “0”, the corresponding profile type is being selected. This means that the type is not selected. The “profile icon file” is an icon design file indicating each profile type, and such an icon file is also stored in the memory 4.

The selection list L2 having such a data structure corresponds to the selection list L stored in the program memory 6.
2 can be created by executing the editing program.

The user can select the selection list L via the operation unit 10
In response to an instruction to edit the profile 2, the device control unit 1 displays each profile type on the display unit 9 by referring to the profile icon file name of the selection list L2 based on the editing program of the selection list L2 stored in the program memory 6. Display the icon. At this time, an icon indicating a profile type whose corresponding flag is “1” (selected state) and an icon indicating a profile type whose corresponding flag is “0” (non-selected state) are visually recognized. Are clearly distinguished. For example, an icon indicating a profile type whose corresponding flag is “1” (selected state) is displayed in color, and an icon indicating a profile type whose corresponding flag is “0” (non-selected state) is monochrome. Is displayed.

In this state, when the user clicks these icons displayed via the operation unit 10, the corresponding flag is set to "1" for the profile type whose flag is "0" (non-selected state). (Selection state), and for the profile type whose flag is “1” (selection state), the corresponding flag is “0”.
(Unselected state). As described above, the icon indicating the profile type whose corresponding flag is “1” (selected state) and the icon indicating the profile type whose corresponding flag is “0” (non-selected state) are visually recognized. Therefore, the user can confirm in real time which profile type is currently selected.

Here, the user sets the flag corresponding to the profile type of the device desired to be connected to “1” (selected state), and sets the flags corresponding to the profile types of other devices to “0” (selected state). ).

On the other hand, when it is desired to change the design of the icon indicating each profile type, the changed icon or icon file name may be dropped on the icon to be changed. Thereby, the corresponding profile icon file name is rewritten with the changed profile icon file name.

The selection list L2 generated in this manner
Is stored in the memory 4, and when the contents are to be updated, the contents can be updated by executing the editing program of the selection list L2 stored in the program memory 6 again.

FIG. 5 is a diagram showing the data structure of the detection list L3 stored in the memory 4.

As shown in FIG. 5, the detection list L3
Is composed of an ID and a profile type corresponding to the ID. The detection list L3 is not a list that can be created and edited by a user's operation like a device list L1 or a selection list L2, but is controlled by the device control unit 1 in a connection terminal selection process (described later) performed at the time of actual connection. Automatically created under

Next, a process from selection of a connection device to actual connection using the Bluetooth terminal according to this embodiment will be described.

FIG. 6 is a flowchart showing a connection terminal selection process using the Bluetooth terminal according to the present embodiment.

First, when the user instructs the execution of the wireless connection by the Bluetooth method via the operation unit 10, the device control unit 1 executes the other standby mode based on the connection terminal selection program stored in the program memory 6. Inquiry to Bluetooth terminal (Inquiry)
Is performed (step S11). The Bluetooth terminal that has received the inquiry transmits its own ID and profile type to the Bluetooth terminal according to the present embodiment that has made the inquiry (step S12).

Next, the device control section 1 creates a detection list L3 based on the collected IDs and profile types of connectable Bluetooth terminals (step S1).
3). After the detection list L3 is created, the device control unit 1 reads the selection list L2 stored in the memory 4 and sets the flag “1” in the selection list L2 among the IDs listed in the detection list L3. The ID of the device having the profile type of (selection state) is activated (step S14), and the flag is set to “1” (selection state) in the selection list L2 among the IDs listed in the device list L1. The ID of the device having the profile type is activated (step S15).

Next, the device control section 1 reads the device list L1 stored in the memory 4, compares the ID listed in the device list L1 with the ID activated in the detection list L3, and It is determined whether a matching ID exists (step S16). As a result, the matching I
If D exists, the corresponding nickname, device profile icon name, and position information are read from the device list L1, and displayed on the display unit 9 while calling attention that connection is possible (step S17). The device control unit 1 further compares the IDs included in the device list L1 with the IDs activated in the detection list L3, and detects the detection list L that is not included in the device list L1.
It is determined whether there is an ID activated in 3 (step S18). As a result, such an ID
If exists, the ID is displayed on the display unit 9 (step S19). The device control unit 1 further checks the ID activated in the device list L1 and the detection list L3.
Is compared with the ID included in the device list L3 to determine whether or not there is an ID that is not included in the detection list L3 but activated in the device list L1 (step S2).
0). As a result, if such an ID exists,
The corresponding nickname device profile icon name and position information are read from the device list L1, and displayed on the display unit 9 while calling attention that connection is not possible (step S21).

Thus, the selection list L is displayed on the display unit 9.
2, information on devices that can be connected (nicknames, icons and positions, or only IDs) and information on devices that cannot be connected (nicknames, icons) for devices having a profile type whose flag is “1” (selected state). And the position) are displayed, and information on the device having the profile type whose flag is “0” (non-selected state) in the selection list L2 is not displayed. In this state, the Bluetooth terminal according to the present embodiment is in a state of waiting for an instruction from the user.

FIG. 7 is a diagram showing an example of the display contents of the display unit 9 in the standby state.

In the example shown in FIG. 7, the display section 9 displays the floor plan of the house created by using the above-mentioned position information input program, and displays the devices already registered in the device list L1. Devices having the selected profile type (here, the television is selected) are displayed at predetermined positions in the floor plan using nicknames and icons. In FIG. 7, devices 11 and 12 are devices that are registered in the device list L1 and are connectable among devices having the selected profile type, and display with nicknames and icons is based on location information. Is displayed, thereby calling attention that connection is possible. The device 13 is a device that is registered in the device list L1 but cannot be connected among devices having the selected profile type. The device 13 displays a nickname and an icon at a location based on the location information. Attention is drawn to the fact that the connection cannot be established by the cross mark on the display. Further, the ID 14 is a device list L1 among devices having the selected profile type.
Is a device that is not registered but can be connected, and only its ID is displayed in the margin of the floor plan.

Although not shown in FIG. 7, the display unit 9
Among the devices to be displayed in the device list L1, only the registered nickname or icon is displayed at a location based on the location information for a device whose one of the nickname and the device icon file name is not registered in the device list L1.
Also, among the devices to be displayed on the display unit 9, the device list L
In 1, for a device for which both the nickname and the device icon file name have not been registered, the ID of the device is displayed at a location based on the location information. Further, the display unit 9
Among the devices to be displayed in, the registered nickname and / or icon are displayed outside the floor plan of the device for which the position information has not been registered.

In a state where such a standby screen is displayed on the display unit 9, the user instructs connection with the device by clicking the device 11, the device 12, or the ID 14 via the operation unit 10. be able to. When the connection device is selected in this manner, the device control unit 1
Transmits its own ID and profile type to the connection destination device (step S22). Thus, the selection of the device to be connected is completed. When the selection of the device to be connected is completed, an authentication process is then performed between the Bluetooth terminal according to the present embodiment as the authentication master and the selected device as the authentication slave. After the connected device is selected, the display of the floor plan and the icons of the devices not selected are deleted from the display unit 9 and only the display of the nickname or the icon of the selected device remains.

FIG. 8 is a flowchart showing an authentication process using the Bluetooth terminal according to the present embodiment.

As shown in FIG. 8, in the authentication process, the authentication master first activates the random number generator 7 to generate a random number, and transmits the random number to the selected authentication slave (step S31). . Then, the operation unit 10
When the PIN information is input by the user via the PC, a link key is generated by a predetermined algorithm based on the random number and the input PIN information (step S32).
Further, the generated link key is encrypted (step S33). Here, the PIN information to be input by the user is:
If the PIN information is the same as the PIN information stored in the memory 4 of the authentication slave and is different from the PIN information, the authentication fails as described below.

On the other hand, when the authentication slave receives the random number (step S34), it reads out the PIN information stored in the memory 4 and, based on the received random number and the read out PIN information, uses a link algorithm by a predetermined algorithm. Is generated (step S35). Further, the authentication slave encrypts the generated link key (step S
36), and transmits the encrypted link key to the authentication master (step S37).

When the authentication master receives the encrypted link key from the authentication slave (step S38), it verifies the encrypted link key generated inside the authentication master with the received encrypted link key. Is performed (step S39). As a result of the collation, if the two match, the authentication process is determined to have succeeded (step S40), and the authentication process ends if the two do not match (step S41).

As described above, if the authentication is successful in the authentication process (step S40), the connection between the authentication master and the authentication slave is established, and if the authentication fails (step S41), both are disconnected.

When the authentication is successful and the connection between the Bluetooth terminal according to the present embodiment, which is the authentication master, and the Bluetooth terminal in the device, which is the authentication slave, is established, data can be transmitted and received between these Bluetooth terminals. Becomes In this case, when transmitting a data file to a device that is an authentication slave, the operation unit 10
, The icon indicating the data file may be dragged and dropped on the icon indicating the connected device. As a result, the data file is transferred to the device that is the authentication slave.

As described above, according to this embodiment, the selection table L2 is referred to when selecting a device to be connected.
Since only devices having the profile type selected in the selection table L2 are displayed on the display unit 9, the user can make such selection extremely easily, and in particular, many Bluetooth terminals within a connectable range. The effect becomes remarkable when exists. This allows
The convenience for the user in selecting a device to be connected is greatly improved.

According to the present embodiment, the device table L1 is referred to when selecting a device to be connected, and a nickname and an icon are displayed on the display unit 9 instead of simply the device ID. Can be done visually. Thereby, the convenience for the user in selecting the device to be connected is further improved.

Further, according to the present embodiment, when selecting a device to be connected, the device table L1 is referred to, and not only the device ID but the position where the device is installed is displayed on the display unit 9. Can make such a selection visually. As a result, the convenience for the user in selecting the device to be connected is further improved.
