And multiple Bluetooth devices, the master Bluetooth device controls the sending and receiving of all data in a micro network. However, this is limited to a micro network. Although the distributed network is mentioned in the Bluetooth specification (S ca 11 ernet) but does not have any specifications for the decentralized network. Although each micro-network forms a decentralized network in Figure 2, the current micro-network (Pic ο net) And the distributed network (Sca 11 ernet) technology and specifications can only send data in the micronet and cannot cross the micronet to make it send data in the distributed network. The link design of the bud decentralized network still has many defects and needs to be improved. Because of this, the inventor, in the spirit of active invention, was thinking of a "chain method of Bluetooth decentralized network" that could solve the above problems.

When the implementation of the Bluetooth distributed network linking method of the present invention consumes Bluetooth wireless bandwidth and affects data transmission and reception bandwidth, as shown in FIG. 3, a Bluetooth base frequency and a physical layer 300, Inter-Link Layer 140 and a baseband driver 130. The Bluetooth baseband and physical layer 300 are dedicated to implement the Link Control Protocol (LMP) and communicate with the baseband driver. 1 3 0 Boundary's far internal connection layer 1 40 is between the logical bond control and the boundary agreement layer 1 1 0 (L 2 CAP) and the base frequency driver 1 3 0. The architecture of the baseband driver is shown in Figure 4.

FIG. 5 shows a preferred embodiment of a method for linking a Bluetooth distributed network according to the present invention, so that Bluetooth devices located in the Bluetooth distributed network can transmit data to each other through packets, wherein the Bluetooth The bud device includes a plurality of link detection timers, a detection program timer, a plurality of master-slave flags, an initial program execution timer, an initial program trigger timer, and a missing timer. The method first executes a The link initial procedure (P 5 0 1), when resetting or initializing a link, decides that the Bluetooth device is the master or slave Bluetooth device in this link, initializes the related timer, and then executes a chain The link search creation process (P 5 0 2) searches for possible paths for data transmission and creates a link path table, and finally executes a link detection process (P 5 0 3). When link-related link detection When the timer expires, start the link detection program to detect the existence of the link. If it does not exist, return to the initial program of the link. If it exists, determine whether to re-execute the initial program of the link P5 0 1), if needed, Then re-execute the link initial procedure (P 5 0 1), if not required, then re-execute the link test procedure (P 5 0 3). Figure 6 shows the steps performed by the link initial program (P501). In step 601, the initial program execution timer is set and enabled. In step 602, when resetting or a link At the beginning of 200412080, the Bluetooth device performed a listening action to detect whether there were any inquiry and paging packets on the Bluetooth wireless channel. In step 603, it is determined whether the Bluetooth device detects any query and call packets. If it is determined that no query and call packets are detected, then step 6 0 5 is performed. If step 6 0 3 It is determined that the Bluetooth device has detected a query and a call packet, then the Bluetooth device is a slave Bluetooth device on the link, and sets the main Park flag of the key to a slave Bluetooth device (step 60). 4) In step 605, a query packet is transmitted, and in step 606, it is determined whether the Bluetooth device has received the response packet of the query packet transmitted in step 605. If it is determined in step 606, The Bluetooth device does not receive the response packet of the query packet transmitted in step 605, and then executes step 608. If it is determined in step 606 that the Bluetooth device has received the query transmitted in step 605 In response to a packet, a call packet is transmitted and a response is received. The Bluetooth device is the master Bluetooth device at the link, and the master-slave flag is set as the master Bluetooth device. In step 608, it is determined whether the initial program execution timer has expired. If it is determined that the timeout has not expired, then return to step 602. If it is determined that the timeout has expired, perform step 609 to set the plural number of the Bluetooth device. Link detection timers, the detection program timer, the missing timer, and the initial program trigger timer, wherein if the Bluetooth device has n links, n links are established and set 9 200412080 Test the timer. In step 6 10, enable the initial program to trigger the timer. FIG. 7 shows the steps performed by the link detection program (P 5 0 3). In step 7 1, when one of the Bluetooth devices was bonded, 5 the key related to the bond was 彳The chastity timer is enabled. In step 702, it is determined whether a plurality of link detection timers of the Bluetooth device have expired. If it is determined in step 702 that the plurality of link detection timers are all If it has not timed out, go back to step 7 0 2.
若步驟7 0 2中判定該複數個鏈結债測計時器 有一逾時，則執行步驟7 0 3，於步驟7 0 3中依據該 主僕旗標之内容判斷該藍芽裝置為主藍芽裝置 或僕藍芽裝置，若步驟70 3中判定為主藍芽裝 置，則啟動一偵測程序並將該偵測程序計時器致 能，同時傳送一鏈結偵測要求以偵測該鏈結是否 仍存在（步驟70 5 );若步驟70 3中判定為僕藍芽裝 置，則啟動一偵測程序並將該偵測程序計時器致 能，同時偵測是否接收到一鏈結偵測要求（步驟 7 04 )。 於步驟7 0 6中判斷該偵測程序計時器是否逾 時，當執行步驟7 0 4後，僕藍芽裝置可接收到一 鏈結偵測要求，或執行步驟7 0 5後，主藍芽裝置 可獲得一回應，則將會判定為未逾時。若步驟7 0 6 中判定該偵測程序計時器未逾時表示該鏈結仍 正常存在，亦即主藍芽裝置仍可透過該鏈結傳遞 封包至相關之僕藍芽裝置俾交換相關資料，故於 10 200412080 步驟7 0 7中藉由該鏈結與相關之僕藍芽裝置交換 相關資料，其中藉由該鏈結與相關之藍芽裝置交 換包含該鏈結之仔列大小（q u e u e s i z e )、資料傳 送時間（data transmission period)及下一次偵 測時間（n e x t d e t e c t i ο n t i m e )等相關資料。If it is determined in step 7 02 that the plurality of linked debt measurement timers have timed out, step 7 0 3 is performed, and in step 7 0 3 the bluetooth device is determined to be the main bluetooth based on the content of the master-slave flag. Device or Bluetooth device, if it is determined as the master Bluetooth device in step 70 3, start a detection process and enable the detection process timer, and send a link detection request to detect the link Whether it still exists (step 70 5); if it is determined as a slave Bluetooth device in step 70 3, start a detection process and enable the detection process timer, and detect whether a link detection request is received (Step 7 04). In step 706, it is determined whether the detection program timer has expired. After performing step 704, the Bluetooth device can receive a link detection request, or after performing step 705, the main Bluetooth The device can get a response and it will be judged as not expired. If it is determined in step 7 06 that the detection program timer has not timed out, the link still exists normally, that is, the master Bluetooth device can still pass packets to the relevant slave Bluetooth device through the link and exchange related data, Therefore, in 10 200412080 step 7 0 7 the related data is exchanged with the related slave Bluetooth device through the link, and the related Bluetooth device is exchanged through the link with the queue size, queue size, Data transmission period (data transmission period) and next detection time (nextdetecti ο ntime) and other related data.
於步驟7 0 8中判斷該初始程序觸發計時器是 否逾時，若步驟7 0 8中判定該偵測程序計時器未 逾時，則執行步驟7 1 1，以重設該鏈結偵測計時 器並致能，再重回步驟7 0 2，若步驟7 0 8中判定該 偵測程序計時器逾時，則執行步驟5 0 1。 若步驟7 0 6中判定該偵測程序計時器逾時， 則將該遺失計時器致能（步驟7 0 9 )，於步驟7 1 0 中判斷該遺失計時器是否逾時，若步驟步驟7 1 0 中判定該遺失計時器逾時，表示該鏈結失敗，此 需執行鏈結搜索及初始化程序，故至該鏈結初始 程序（P 5 0 1 )，若步驟7 1 0中判定該遺失計時器未 逾時，表鏈結仍然存在，故執行步驟7 0 7。In step 708, it is determined whether the initial program trigger timer has expired. If it is determined in step 708 that the detection program timer has not expired, then step 7 1 1 is performed to reset the link detection timer. The device is enabled, and then returns to step 702. If it is determined in step 708 that the detection program timer has expired, step 501 is performed. If it is determined in step 7 06 that the detection program timer has expired, enable the missing timer (step 7 0 9), and determine whether the lost timer has expired in step 7 1 0. If step 7 It is determined in 10 that the missing timer has expired, indicating that the link has failed. This requires a link search and initialization procedure. Therefore, the link initial procedure (P 5 0 1) is performed. If the loss is determined in step 7 10 If the timer has not expired and the watch link still exists, go to step 7 0 7.
