Description of the invention (2) (Host Controller Interface) instruction periodic inspection Link quality value. The second purpose of the present invention is to provide a settable alarm method for the Bluetooth device to contact i abnormality. When the detected quality value is lower than the comparison value, the central processor of the Bluetooth device sends an alarm signal through the alarm element. (Such as vibrate, ring, or display) to remind users of Bluetooth devices. Another object of the present invention is to provide a configurable Bluetooth device connection abnormality warning method, with a warning signal to remind the user that the user can handle it in a timely manner (such as reducing the distance between the two devices) to reduce the probability of the connection being interrupted 〇 Another object of the present invention is to provide a settable bluetooth device connection abnormality warning method. When the quality value returns to a higher value, the device in the central processing unit stops issuing the warning. Another object of the present invention is to provide a settable Bluetooth device connection abnormality warning method, which allows a user to adjust the distance between two Bluetooth devices that have established a connection, and averages the quality values read several times at that time. The value is used as a comparison value to meet the needs of contact anomaly warning for different users, so that different users can have contact anomaly warning settings at different distances. These and other objects, features, and advantages of the present invention will become clearer to those skilled in the art through the following description in conjunction with the drawings. [Detailed description of the invention] First, please refer to FIG. 1. Figure 1 is a message flow chart for checking the quality of the link after the two Bluetooth devices are connected. It can be seen from the figure that when two Bluetooth 530467 devices are used to establish a connection relationship, one of the Bluetooth devices will issue a query command (step 1 1) from the central processing unit to the other through the Bluetooth module. In the Bluetooth module of a Bluetooth device, the central processing unit of the other Bluetooth device will perform an inquiry scan (step 12), and when the Bluetooth device sending the inquiry receives an answer from another Bluetooth device, After that, the Bluetooth module will send back a signal to the central processing unit (step 13), the central processing unit is the next connection establishment instruction to the bluetooth module (step 14), the bluetooth module After receiving the instruction, the central processing unit is notified with the established contact (step 15). After the two Bluetooth devices are connected, the central processing unit of either Bluetooth device periodically sends an HCI (Host Controller Interface) command to the Bluetooth module to check the Link quality value (step 16). When the command is received, the central processing unit link quality value is reported (step 17). Repeat steps 16 and 17 periodically to get the quality value at any time. The above HC I refers to the interface used to transfer data or instructions between the Bluetooth device controller and the Bluetooth chip module, and the HC I instruction is the instruction used by the Bluetooth device controller to control the Bluetooth chip module, and These are well known to those skilled in the art, so I won't go into details here. Please refer to Figure 2 again, which is a software control flow chart. As shown in the figure, after the Bluetooth device is turned on (step 20), wait to establish a connection with another Bluetooth device (step 21), and check whether a connection is established with another Bluetooth device (step 2 2). If it is, then go back to step 21 and continue reading to confirm the establishment of the connection; if it is confirmed that the connection is established with another Bluetooth device, set the warning flag to 0 (this situation is the establishment of the connection without any abnormality) (step 2 3), you can start to check the link quality timing _ (step

Description of the invention (4) | 24) After entering the wait event state (step 25). ! On til it? After the event (steps), the following four types of skin processors can determine whether it is lower than the comparison value. At this time, the central I is lower than the comparison value (that is, there is no abnormality == a. Right quality value). If not, then confirm whether the warning flag is "" (also g θ or different two have been arranged,) 'At this time) (step 291), if no, the Lu Bu signal is still being issued, then directly enter the waiting event ( The steps are shown in the table * The device is not in the alert (that is, an abnormality has occurred previously and is currently in the second row (94); the right alert is not flagged as 1 0 (step 292), and the alert is stopped) \ The alert flag is set back to the status (Step 294). After the above ^ 293) directly enter the wait for the value is lower than the comparison value, contact abnormal heart step two, / determine the quality of the connection (step 2 95) and set the warning flag to 丨 (step 29 6) and enter the waiting state ( Step 2 9 7). The second condition is that the time for checking the connection quality timer has expired (step 27). At this time, the timer must be reset (step 271), and then the command for checking the connection quality (step 272) is sent to enter the waiting event state (step 273). . These steps have the effect of periodically checking the value of the link quality. The third condition is the setting of the comparison value. First, the user adjusts the distance between the two Bluetooth devices (step 251), where the distance can be adjusted to the longest distance of the hope warning, and then reads the average value of the connection quality several times as a comparison value (step 2 5 2 ), Then, determine whether the comparison value obtained in the above step is higher than a preset value (step 253), and the preset value may be a preset maximum value. If it is higher than the preset value, the preset value is used as the comparison value (step 2 5 6) 530467 5. After the invention description (5) enters the waiting event state (step 2 5 5); if the comparison value is not higher than the preset value Value, the previously stored comparison value is updated to the above-obtained comparison value (step 2 54), and a wait event state (step 255) is entered to complete the setting of the entire comparison value. The last condition is that when the Bluetooth device is to be disconnected (step 28), the timer is stopped (step 281) and a waiting is made to establish contact with another Bluetooth device (step 282). Finally, see Figure 3. Figure 3 is a schematic diagram when two Bluetooth devices are connected. It can be seen from the figure that the general Bluetooth device 30 includes a Bluetooth module 3, a memory 32, and a central processing unit 33. The Bluetooth module 31 includes a radio frequency unit 311 (RF unit) and a base frequency unit 312 ( Baseband unit) and an external antenna 35 is connected. When the two Bluetooth devices are to establish a connection season, a connection relationship is established through the connection between the central processing unit 3 3, the Bluetooth module 3 1 and the antenna 35 to issue and receive instructions, which is well known to those skilled in the art. So I won't go into details here. In the present invention, alarms 34 such as a bell 3 4 1 and a vibration motor 3 4 2 are added. By the method described above, the alarm can be activated to achieve the alarm effect of abnormal Bluetooth connection. The logic concepts and matching circuits used in the above methods are easily understood and implemented by those skilled in the art, and they are not the focus of the present invention, so they are not repeated here. The method disclosed in the present invention can periodically check the connection quality value, and can send a warning signal to remind the user when the Bluetooth device is abnormally connected, so as to reduce the probability of interruption of the connection between the Bluetooth devices. Checking the connection quality value, no invention with the same purpose was found. So this invention
