Description

  The present invention relates to a Bluetooth device, and more particularly, to a Bluetooth device that can immediately switch a connection target.

  Bluetooth is a wireless personal area network (Wireless PAN). Developed by Ericsson, then technical standards were established by the Bluetooth Special Interest Group (SIG).

  Initially, Bluetooth was used for wireless communication between mobile phones and hands-free devices and has changed since then, with a wide range of applications. For example, a wireless network between short-distance computers, a wireless connection between computers and peripheral devices (mouse, earphone microphone, printer, etc.), file transmission between Bluetooth devices, wireless wired devices, wireless application protocols, and the like. Due to its wide range of applications, most of the new notebook computers now have a built-in Bluetooth function that can be paired with various Bluetooth devices. Since Bluetooth is a short-range wireless personal area network, many computer peripheral devices, such as keyboards, mice, earphones, and speakers, all use Bluetooth as a communication protocol, and their convenience is unquestionable. . However, there are still some parts of Bluetooth devices that are troublesome in use.

  As is well known to general Bluetooth users, Bluetooth devices can be paired with various hosts (computers, mobile phones, etc.), but after confirming pairing, one Bluetooth device Pairing can only be done with one host that has been paired. In other words, it is a one-to-one format and must be paired first before use. For example, in the case of pairing one Bluetooth keyboard and one computer as a host, the Bluetooth keyboard is first activated, and the computer is searched for the Bluetooth keyboard. As soon as the user selects the Bluetooth keyboard, an encryption key (passkey or passcode) consisting of several sequences is generated. When the user inputs this encryption key to the Bluetooth keyboard, the pairing setting is completed.

  When the Bluetooth keyboard is paired with a host computer, it does not need to be newly set when it is used again. However, when the Bluetooth keyboard is paired with a different computer and used, it is necessary to perform pairing every time the host computer is replaced, and to set again a new computer even if it is already used. This is because the encryption key must be exchanged when pairing the Bluetooth keyboard and the host computer. The Bluetooth keyboard performs encryption using a different encryption key, and transmits data with the computer so that the transmitted data is not received by other computers.

  As can be seen from the above, the Bluetooth device can be paired with a plurality of different host devices, but the connection can be used only in a one-to-one mode, and the connection target of the Bluetooth device is the host. When changing from one computer to another, it must be paired with another computer. If you want to restore the connection to the original computer, the encryption key has already been changed and must be set again. For users who have a plurality of host devices and use the Bluetooth device jointly, it can be easily inferred that this method of use is inconvenient.

  Therefore, a main object of the present invention is to provide a Bluetooth device that can immediately switch a connection target. Hosts that have already been paired can be easily switched, and there is no need to go through a complicated pairing setup process. This effectively solves the problem that exists when changing the connection target of a Bluetooth device.

  In order to achieve the above object, as the main technical means taken, the Bluetooth device includes a controller, a Bluetooth wireless module, and an instruction unit.

  The controller has a switching and saving function. The controller has one or more input ports, one or more output ports, and input / output ports, and one or more selector switches are provided in the input ports.

  The Bluetooth wireless module is connected to an input / output port of the controller, and the controller transmits and receives signals using a Bluetooth communication protocol.

  The instruction unit is connected to the output port of the controller, generates one or more pieces of identification information, and indicates the connection target of the Bluetooth device.

  The controller of the Bluetooth device stores setting data when paired with the host in the past. Each setting data corresponds to identification information generated by the instruction unit. When you want to pair the Bluetooth device with a different host, you only need to select the setting data of the host you want to pair by using the switch and executing the switching function built in the controller. The instruction unit displays the identification information corresponding to the selected host so that the user can confirm, and the switching of the connection target is easily completed. There is no need to repeat the setting process. As a result, when the connection target of the Bluetooth device is changed, it is necessary to newly confirm pairing, which effectively solves the inconvenient existing problem.

FIG. 3 is a schematic external view of the first preferred embodiment of the present invention. FIG. 4 is a schematic external view of a second preferred embodiment of the present invention. FIG. 5 is a schematic external view of a third preferred embodiment of the present invention.

  The basic architecture of the present invention includes a controller 10, a Bluetooth radio module 20, and an instruction unit 30, as shown in FIG.

  The controller 10 is composed of a microprocessor chip and has switching and storage functions. The controller 10 has one or more input ports, one or more output ports, and one or more input / output ports (I / O). Further, a changeover switch 11 is provided at the input port of the controller 10. The changeover switch 11 is a control interface used for switching the connection target of the Bluetooth device. However, when the Bluetooth device is a single keyboard, the changeover switch 11 may be one key in the standard keyboard layout or an independent key other than the standard keyboard layout. It may be a combination key (two or more keys) having a function definition in a standard keyboard layout.

  The Bluetooth wireless module 20 includes a wireless unit 21, an antenna 22, and a control unit. In this embodiment, the control unit of the Bluetooth wireless module 20 is matched by the controller 10. Since the Bluetooth wireless module 20 is a known component and is not part of the main technical features of the present invention, its detailed structural state will not be described in detail.

  The instruction unit 30 is provided at an output port of the controller 10 and generates information for identifying a connection target. The information may be numbers, symbols or colors. In a specific embodiment, the pointing unit 30 may be a display, such as a liquid crystal display, a 7 segment display, or the like. In the case of a liquid crystal display, a design (for example, the letter “rice”) and a number (number) can be displayed. In the case of a 7-segment display, a number is simply displayed. In addition to the display, the indication unit 30 may be composed of one or more light emitting diodes, including a combination of indicator lights composed of a plurality of light emitting diodes, or a single LED capable of generating two or more colors of light. It is. The former shows different connection objects by lighting different light emitting diodes, and the latter represents different connection objects with light beams of different colors.

  Using the technology, the Bluetooth device can easily switch between each paired host. After switching the connection target, it is not necessary to go through any setting process and can be used directly.

  The pairing method of the Bluetooth device and the host is the same as that of the conventional Bluetooth device. The differences are the following parts. After starting the Bluetooth device, first, the selector switch 11 is used to select one piece of identification information (for example, a number) in order to connect to the host. The identification information is displayed on the instruction unit 30. The subsequent setting process is the same as that of the conventional Bluetooth device. If the Bluetooth device is a keyboard, the host searches for the Bluetooth keyboard. Furthermore, as soon as the user selects the Bluetooth keyboard, a set of encryption keys is generated on the host side. Pairing is completed as soon as the user enters the encryption key into the Bluetooth keyboard. The encryption key is stored by the controller 10 and an association with the identification information displayed on the instruction unit 30 is established. Using the method, different identification information is given to different hosts, and pairing of the Bluetooth keyboard and the different hosts is completed.

  When the pairing of the Bluetooth keyboard and the plurality of hosts is completed, it is not necessary to repeatedly set any of the connections with the hosts described above. When a Bluetooth keyboard is paired with one of the hosts and then switched to a paired connection with another host, the user only needs to use the changeover switch 11 to select the host to be connected (instructions Confirm through the information displayed by the unit 30). The controller 10 encrypts data using the encryption key corresponding to this information, and then transmits the data to the host to configure the connection with the host. In other words, the user can easily complete the switching of the connection target only by pressing the single key and does not need to repeat any setting process.

  In the above description, a Bluetooth keyboard is taken as an example, and an electric circuit diagram for executing the embodiment is as shown in FIG. In this embodiment, the controller 10 is an encoding circuit, and its leads S0 to S18 and R0 to R7 are connected to the keyboard array 12 shown on the right side of the drawing. The changeover switch 11 of the controller 10 is composed of keys (Muti-ID) of the keyboard array 12.

  The instruction unit 30 is configured by a 7-segment display, and the displayed number is information for identifying a connection target (a host to be connected is identified by a number). A specific implementation method is as shown in FIG. 3, and a 7-segment display 41 is installed at one corner of the keyboard 40. When the changeover switch (not shown) is switched, the 7-segment display 41 can display the identification information in the numerical format, and the user can confirm the selection.

  Furthermore, although the said Example has taken the Bluetooth keyboard as an example, use of the Bluetooth apparatus of the said technique is not restrict | limited to a keyboard. In addition to keyboards, it is used for Bluetooth mice, Bluetooth earphones, Bluetooth speakers, Bluetooth joysticks, etc. Shown in FIG. 4 is a Bluetooth mouse 50.
