Description

Technical Field

[0001] The present invention belongs to the technical field of Bluetooth connection, and in particular relates to a method, device, electronic equipment and computer storage medium for establishing a Bluetooth connection. Background Art

[0002] The existing Bluetooth connection process is based on the Bluetooth standard protocol. The device initiating the connection initiates the paging process and sends identification (ID) packets in a continuous manner. The connected end starts the paging scan process and periodically receives the ID packets sent by the device initiating the connection. When the ID packet is received and replied, the device initiating the connection will send a Filesystem Hierarchy Standard (FHS) packet, and then the page process ends and the Asynchronous Connectionless Link (ACL) begins to be established.

[0003] It can be seen that the related technology is to continuously send ID packets in order to receive the ID packets at the connected end. However, since there is no more frequency modulation information, the frequencies of the device initiating the connection and the connected end may not correspond. In other words, even if the time when the device initiating the connection sends the ID packet and the time when the connected end receives the ID packet correspond, it may still not be received due to the wrong frequency.

[0004] Therefore, how to improve the efficiency of establishing a Bluetooth connection is a technical problem that those skilled in the art need to solve urgently. Summary of the invention

[0037] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0039] The existing Bluetooth connection process is based on the Bluetooth standard protocol. The device initiating the connection initiates the paging process and sends identification (ID) packets in a continuous manner. The connected end starts the paging scan process and periodically receives the ID packets sent by the device initiating the connection. When the ID packet is received and replied, the device initiating the connection will send a Filesystem Hierarchy Standard (FHS) packet, and then the page process ends and the Asynchronous Connectionless Link (ACL) begins to be established.

[0040] It can be seen that the related technology is to continuously send ID packets in order to receive the ID packets at the connected end. However, since there is no more frequency modulation information, the frequencies of the device initiating the connection and the connected end may not correspond. In other words, even if the time when the device initiating the connection sends the ID packet and the time when the connected end receives the ID packet correspond, it may still not be received due to the wrong frequency.

[0041] In order to solve the problems in the prior art, the embodiments of the present invention provide a method, device, electronic device and computer storage medium for establishing a Bluetooth connection. The method for establishing a Bluetooth connection provided by the embodiments of the present invention is first introduced below.

[0042] Figure 1 FIG. 1 is a flow chart showing a method for establishing a Bluetooth connection provided by an embodiment of the present invention. Figure 1 As shown, the Bluetooth connection establishment method is applied to a first Bluetooth device and may include the following steps:

[0043] S101. Acquire clock information and frequency information of a second Bluetooth device.

[0044] In one embodiment, when the second Bluetooth device is in an inquiry scan state and a paging scan state, and the first Bluetooth device performs an inquiry operation, the clock information and frequency information of the second Bluetooth device are obtained, including: receiving an FHS packet sent by the second Bluetooth device; parsing the FHS packet to obtain the clock information and frequency information.

[0045] In one embodiment, after receiving the File System Hierarchy Standard FHS package sent by the second Bluetooth device, the method further includes: parsing the FHS package to obtain device address information and device identification information of the second Bluetooth device.

[0046] In one embodiment, acquiring the clock information and the frequency information of the second Bluetooth device includes: acquiring the clock information and the frequency information through a wireless network.

[0047] S102: Determine a target Bluetooth frequency hopping sequence according to the clock information and the frequency information.

[0048] S103: Establish an asynchronous connectionless connection with a second Bluetooth device based on the target Bluetooth frequency hopping sequence.

[0049] It can be seen that this method determines the target Bluetooth frequency hopping sequence according to the clock information and frequency information of the second Bluetooth device. Through the frequency sequence selection mechanism, it can largely avoid the problem of low connection efficiency caused by frequency correspondence problems, thereby improving the efficiency of establishing Bluetooth connections.

[0050] The above-mentioned method for establishing a Bluetooth connection is specifically described below with reference to a scenario embodiment.

[0051] Assume that device A wants to initiate a Bluetooth connection with device B, and device B is in the state of fully opening the inquiry scan and paging scan. First, device A initiates the inquiry process and receives the FHS packet of device B to obtain the device address, device name, and clock information of device B. Then, after device A parses this information, it initiates the page process for the Bluetooth address corresponding to device B. Before initiating the process, the clock information in the FHS packet is transmitted to the controller of classic Bluetooth (BT). The controller selects the Bluetooth frequency hopping sequence (A train or B train) based on the bit16 of its own clock and the corresponding relationship with the bit16 of the clock of device B.

[0052] The advantage of the present invention is that the selection of Bluetooth frequency hopping sequence can be optimized by calculation before initiating the page process, and the frequency hopping sequence of the connected device can be quickly located. In the receiving window corresponding to a scan cycle, the ID packet will not be received due to the wrong frequency point, thereby avoiding the problem of connection failure, thereby achieving fast and reliable connection.

[0053] The following is an explanation with specific experimental data.

[0054] Name of the device initiating the connection: A. Name of the connected device: B

[0055] Experimental conditions: B is in the inquiry scan and page scan states, with cycles of 1.28s and receiving windows of 20ms respectively. A initiates a connection to B using the Bluetooth connection establishment method provided by the prior art and the embodiment of the present application respectively, with a page cycle of 1.28s.

[0056] Experimental results:

[0057] (1) Experimental results of the prior art: When device B is in the A train, the probability of connecting in 1.28 seconds is 100%; when it is in the B train, the probability of connecting in 1.28 seconds is 0.

[0058] (2) Experimental results of the present invention: Regardless of whether B is in the A train or the B train, the probability of connecting in 1.28s is 100%.

[0059] It can be seen from the experimental results that the Bluetooth connection establishment method provided in the embodiment of the present application greatly improves the connection efficiency.

[0063] The connection establishing module 203 is configured to establish an asynchronous connectionless connection with a second Bluetooth device based on a target Bluetooth frequency hopping sequence.
