Description

Bluetooth connection establishment method and device, electronic equipment and computer storage medium

Technical Field

The present application relates to the field of bluetooth connection technologies, and in particular, to a bluetooth connection establishment method, a device, an electronic apparatus, and a computer storage medium.

Background

The existing bluetooth connection process is based on the bluetooth standard protocol, and the device end initiating the connection initiates a paging (page) process to send identification (id) packets in a continuous manner. The connected end starts a page scan (page scan) process, and periodically receives id packets sent by the device end initiating the connection. When the id packet is received and replied to, the device side initiating the connection will send a file system layering criteria (Filesystem Hierarchy Standard, FHS) packet, immediately after the page flow ends, the asynchronous connectionless (Asynchronous Connectionless Link, ACL) begins to build.

It can be seen that, in the related art, id packets are continuously transmitted to obtain that the connected end receives the id packets, but since there is no more frequency modulation frequency point information, the frequency points of the device end initiating connection and the connected end may not correspond. That is, even if the time for the device side initiating the connection to transmit the id packet and the connected side to receive the id packet corresponds, it may not be received because the frequency points are not aligned.

Therefore, how to improve the efficiency of bluetooth connection establishment is a technical problem that needs to be solved by those skilled in the art.

Therefore, according to the method, the target Bluetooth frequency hopping sequence is determined according to the clock information and the frequency point information of the second Bluetooth device, and the problem of low connection efficiency caused by the problem of frequency point correspondence can be avoided to a great extent through a selection mechanism of the frequency point sequence, so that the efficiency of Bluetooth connection establishment is improved.

The following describes the bluetooth connection establishment method in detail in a scenario embodiment.

Assuming that the a device is to initiate a bluetooth connection to the B device, the B device is in a full on state for inquiry scan (inquiry scan) and page scan (page scan). Firstly, the equipment A initiates an inquiry process, receives an FHS packet of the equipment B, and obtains the equipment address, the equipment name, the clock information and the like of the equipment B. And then after the A device analyzes the information, initiating a page process for the Bluetooth address corresponding to the B device. Before initiating the flow, clock information in the FHS packet is transmitted to a controller (controller) of classical Bluetooth (BT), and the controller selects Bluetooth frequency hopping sequences (Atrain or B train) according to bit16 of the clock and the corresponding relation with bit16 of the clock of the B device.

The application has the advantages that the selection of the Bluetooth frequency hopping sequence can be optimized by calculation before the page process is initiated, and the frequency hopping sequence in which the connected equipment is positioned can be positioned quickly. Under the receiving window corresponding to one scan period, the id packet cannot be received due to the fact that frequency points are not opposite, and the problem of connection failure is avoided, so that quick and reliable connection is achieved.

The following is a description of specific experimental data.
