Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
In the following description, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not for indicating or implying a relative importance or order.
First, an application scenario of the present disclosure will be described. The Bluetooth connection establishment method and device can be applied to the scene that Bluetooth devices establish Bluetooth connection, in the related technology, two Bluetooth devices establishing Bluetooth connection are different types of Bluetooth devices, namely one Bluetooth device is a master device, and the other Bluetooth device is a slave device. In the Bluetooth connection process, the slave device is used for broadcasting a Bluetooth connection message, and the master device is used for scanning the Bluetooth connection message broadcast by the slave device and establishing Bluetooth connection with the slave device according to the Bluetooth connection message after scanning the Bluetooth connection message broadcast by the slave device. However, the inventor finds that, in the case that both bluetooth devices are master devices or slave devices, the two bluetooth devices cannot establish bluetooth connection, for example, if both bluetooth devices are master devices, since both the two master devices can only scan bluetooth connection messages and cannot broadcast bluetooth connection messages, both the two master devices cannot scan bluetooth connection messages, and thus cannot establish bluetooth connection of the two master devices; for another example, if both bluetooth devices are slave devices, both slave devices cannot scan bluetooth connection messages because both slave devices can only broadcast bluetooth connection messages, and therefore, both slave devices cannot scan bluetooth connection messages, so that bluetooth connection of both slave devices cannot be established.
In order to solve the above problems, the present disclosure provides a bluetooth connection method, apparatus, storage medium, and electronic device, where a first bluetooth device alternately executes a first bluetooth connection event and a second bluetooth connection event, and if a bluetooth connection response message sent by the second bluetooth device is received in the case of executing the first bluetooth connection event, establishes a bluetooth connection with the second bluetooth device; or under the condition of executing the second Bluetooth connection event, if the second Bluetooth connection message broadcasted by the second Bluetooth device is scanned, establishing Bluetooth connection with the second Bluetooth device according to the second Bluetooth connection message. Thus, since the first bluetooth connection event and the second bluetooth connection event are alternately performed, a bluetooth connection can be established for the same type of bluetooth device; in addition, when establishing bluetooth connection, need not the master-slave identity of fixed bluetooth equipment to the operational complexity when having simplified bluetooth equipment and connected has improved bluetooth connection's speed.
The bluetooth device mentioned in the present disclosure may be a bluetooth speaker, a smart phone, a bluetooth headset, a smart desk lamp, etc. capable of bluetooth connection, and of course, the above devices are only examples, which are not limited in this disclosure. The first bluetooth device and the second bluetooth device in the present disclosure may be the same type of device, or may be different types of devices.
Fig. 1 is a flowchart of a bluetooth connection method according to an embodiment of the present disclosure, where the method is applied to a first bluetooth device. As shown in fig. 1, the method may include:
s101, alternately executing a first Bluetooth connection event and a second Bluetooth connection event.
Wherein the first bluetooth connection event includes broadcasting a first bluetooth connection message and the second bluetooth connection event includes scanning for a second bluetooth connection message; the event execution time of the first bluetooth connection event and the second bluetooth connection event at each execution is randomly determined.
It should be noted that the first bluetooth device may receive the bluetooth connection request message, and alternately perform the first bluetooth connection event and the second bluetooth connection event in response to receiving the bluetooth connection request message. One possible implementation manner is that when the first bluetooth device is turned on, the first bluetooth device receives the bluetooth connection request message, for example, a switch key is provided on the first bluetooth device, when the first bluetooth device is turned off, if the switch key is triggered, the first bluetooth device is turned on, at this time, the first bluetooth device receives the bluetooth connection request message, so that after the first bluetooth device is turned on, the first bluetooth device can automatically enter a bluetooth connection mode without manual operation, thereby making the operation of bluetooth connection simpler.
Another possible implementation manner is that a bluetooth switch is provided on the first bluetooth device, where the bluetooth switch is used to turn on a bluetooth connection mode, and after the bluetooth switch is triggered, the first bluetooth device may receive the bluetooth connection request message, so that a user may control whether to turn on the bluetooth connection mode according to needs, so that the controllability of the first bluetooth device is stronger.
In this step, after receiving the bluetooth connection request message, the first bluetooth device may determine a first event execution time for executing the first bluetooth connection event, and execute the first bluetooth connection event at the first event execution time; thereafter, the first bluetooth device may determine a second event execution time at which a second bluetooth connection event is executed, and execute the second bluetooth connection event at the second event execution time. If the first bluetooth device does not establish a bluetooth connection at the first event execution time and the second event execution time, the first bluetooth device may redetermine a new first event execution time and execute the first bluetooth connection event at the new first event execution time, and then the first bluetooth device may redetermine a new second event execution time and execute the second bluetooth connection event at the new second event execution time.
It should be noted that, the first bluetooth device may determine a first event execution time before executing the first bluetooth connection event, and determine a second event execution time before executing the second bluetooth connection event; the first event execution time and the second event execution time may also be determined simultaneously before the first bluetooth connection event and the second bluetooth connection event are executed, and after the first bluetooth connection event is executed at the first event execution time, the second bluetooth connection event is executed at the second event execution time, which is not limited in the present disclosure.
The first event execution time and the second event execution time may be any values within a preset time interval, for example, the preset time interval may be 300ms to 3s, and the first bluetooth device may determine that the first event execution time is 300ms and determine that the second event execution time is 450ms; the first bluetooth device may also determine that the first event execution time is 1.5s, and determine that the second event execution time is 2s; the first bluetooth device may also determine that the first event execution time is 3s and the second event execution time is 2.5s, which is not limited by the present disclosure.
Taking two bluetooth speakers as an example, if a first bluetooth speaker determines that the execution time of a first event is 500ms after receiving a bluetooth connection request message, determines that the execution time of a second event is 800ms, broadcasts the first bluetooth connection message at the execution time of the first event, and scans the second bluetooth connection message at the execution time of the second event; if the second bluetooth speaker receives the bluetooth connection request message, it also determines that the execution time of the first event is 500ms, determines that the execution time of the second event is 800ms, broadcasts the second bluetooth connection message at the execution time of the first event, and scans the first bluetooth connection message at the execution time of the second event. If the first bluetooth speaker and the second bluetooth speaker receive the bluetooth connection request message simultaneously, the first bluetooth speaker and the second bluetooth speaker cannot scan the bluetooth connection message broadcasted by the opposite side at the first event execution time and the second event execution time, and the first bluetooth speaker and the second bluetooth speaker cannot establish bluetooth connection.
Further, the first bluetooth speaker may re-determine that the new first event execution time is 700ms, determine that the new second event execution time is 1s, broadcast the first bluetooth connection message at the new first event execution time, and scan the second bluetooth connection message at the new second event execution time; the second bluetooth speaker may also re-determine the new first event execution time to be 1s, determine the new second event execution time to be 500ms, and broadcast the second bluetooth connection message at the new first event execution time, and scan the first bluetooth connection message at the new second event execution time. Because the first bluetooth speaker starts to scan the second bluetooth connection message at the new second event execution time, the second bluetooth speaker also broadcasts the second bluetooth connection message at the new first event execution time, and thus the first bluetooth speaker can scan the second bluetooth connection message broadcast by the second bluetooth speaker.
In one possible implementation, the first bluetooth device may also receive a connection event selection instruction, where the connection event selection instruction may be used to instruct to execute the first bluetooth connection event or the second bluetooth connection event, and after receiving the connection event selection instruction, the first bluetooth device executes the first bluetooth connection event or the second bluetooth connection event according to the connection event selection instruction.
For example, the connection event selection instruction may include a first connection event selection instruction for instructing the first bluetooth device to broadcast the first bluetooth connection message and a second connection event selection instruction for instructing the first bluetooth device to scan for the second bluetooth connection message. The first bluetooth device may receive a connection event selection instruction triggered by a user through an instruction switch, for example, the instruction switch may include a first position and a second position, and when the instruction switch is switched to the first position, the first bluetooth device may receive the first connection event selection instruction; the first bluetooth device may receive a second connection event selection instruction when the instruction switch is switched to the second position. The first bluetooth device may broadcast a first bluetooth connection message after receiving the first connection event selection instruction, and the first bluetooth device may scan for a second bluetooth connection message after receiving the second connection event selection instruction.
In addition, if the first bluetooth device can only broadcast the first bluetooth connection message or scan the second bluetooth connection message, a bluetooth connection event allowed to be executed by the first bluetooth device may be preset, and after the first bluetooth device receives the bluetooth connection request message, the first bluetooth device starts to execute the preset bluetooth connection event; if the second bluetooth device can broadcast the second bluetooth connection message or scan the first bluetooth connection message, the second bluetooth device can determine a bluetooth connection event to be executed through the received connection event selection instruction. For example, if the first bluetooth device can only broadcast the first bluetooth connection message, the first bluetooth device may broadcast the first bluetooth connection message after receiving the bluetooth connection request message; if the second bluetooth device can broadcast the second bluetooth connection message or scan the first bluetooth connection message, the instruction switch of the second bluetooth device can be switched to the second position, and the second bluetooth device can scan the first bluetooth connection message broadcast by the first bluetooth device after receiving the second connection event selection instruction. In this way, when the bluetooth device establishes a bluetooth connection, a bluetooth connection event that the bluetooth device is allowed to perform can be determined according to the hardware configuration of the bluetooth device, so that more bluetooth devices can be adapted.
It should be noted that, the execution sequence of the first bluetooth connection event and the second bluetooth connection event may be random, for example, the first bluetooth device may randomly determine the execution sequence of the first bluetooth connection event and the second bluetooth connection event when determining the execution time of the first event and the execution time of the second event; the execution order of the first bluetooth connection event and the second bluetooth connection event may also be preset, for example, the first bluetooth device preset to execute the second bluetooth connection event at the first event execution time, and then execute the first bluetooth connection event at the second event execution time.
S102, under the condition of executing the first Bluetooth connection event, if a Bluetooth connection response message sent by the second Bluetooth device is received, establishing Bluetooth connection with the second Bluetooth device.
In this step, in the process that the first bluetooth device broadcasts the first bluetooth connection message during the execution time of the first event, if the second bluetooth device receives the first bluetooth connection message and determines that the first bluetooth device meets the bluetooth connection condition preset by the second bluetooth device according to the first bluetooth connection message, a bluetooth connection response message may be sent to the first bluetooth device. After receiving the bluetooth connection response message sent by the second bluetooth device, the first bluetooth device may establish a bluetooth connection with the second bluetooth device according to the bluetooth connection response message.
For example, if the first bluetooth device is a bluetooth speaker a, the second bluetooth device is a bluetooth speaker B, and the bluetooth speaker a needs to team with the bluetooth speaker B closest to the bluetooth speaker a, a device identifier of the bluetooth speaker allowed to team with the bluetooth speaker a may be preset, for example, may be "speaker B". After receiving the Bluetooth connection message, the Bluetooth sound box A can determine whether the equipment identifier in the Bluetooth connection message is a sound box B, and if the equipment identifier is the sound box B, the Bluetooth connection response message can be sent to the Bluetooth sound box B.
And S103, under the condition of executing the second Bluetooth connection event, if the second Bluetooth connection message broadcasted by the second Bluetooth device is scanned, establishing Bluetooth connection with the second Bluetooth device according to the second Bluetooth connection message.
In this step, in the process that the first bluetooth device scans the second bluetooth connection message at the execution time of the second event, if the second bluetooth connection message broadcasted by the second bluetooth device is scanned, it may be determined whether the second bluetooth device meets a preset bluetooth connection condition according to the second bluetooth connection message. If the second Bluetooth device meets the preset Bluetooth connection condition, a Bluetooth connection establishment message can be sent to the second Bluetooth device, and after the second Bluetooth device receives the Bluetooth connection establishment message sent by the first Bluetooth device, the second Bluetooth device can establish Bluetooth connection with the first Bluetooth device according to the Bluetooth connection establishment message.
Wherein the second bluetooth connection message may include at least one of signal strength and device information, which may include a device type, a device name, a bluetooth address, etc. If the signal intensity in the second Bluetooth connection message is larger than a preset intensity threshold value under the condition that the second Bluetooth connection message comprises the signal intensity, determining that the second Bluetooth device meets preset Bluetooth connection conditions; if the second Bluetooth connection message comprises equipment information, if the equipment information in the second Bluetooth connection message is the same as the preset pairing equipment information, determining that the second Bluetooth equipment meets the preset Bluetooth connection condition; and under the condition that the second Bluetooth connection message comprises signal intensity and equipment information, if the signal intensity in the second Bluetooth connection message is larger than a preset intensity threshold value and the equipment information in the second Bluetooth connection message is the same as the preset pairing equipment information, determining that the second Bluetooth equipment meets the preset Bluetooth connection condition.
Here, the preset intensity threshold may be determined according to a distance between two bluetooth devices that need to establish bluetooth connection, for example, bluetooth speaker a needs to team with bluetooth speaker B closest to bluetooth speaker a, and then may obtain a signal intensity of bluetooth speaker B received by bluetooth speaker a at a current distance, and use the signal intensity as the preset intensity threshold. The preset pairing device information may be a device type, a device name, a bluetooth address, or other information customized by a user, for example, a customized device name, etc., and the content of the preset pairing device information is not limited in this disclosure.
For example, if the first bluetooth device is a bluetooth speaker a, the second bluetooth device is a bluetooth speaker B, and the bluetooth speaker a needs to be formed with the bluetooth speaker B closest to the bluetooth speaker a, then a preset bluetooth connection condition of the bluetooth speaker a may be preset to be that the signal strength is greater than a preset strength threshold. The preset intensity threshold may be determined according to a distance between the bluetooth speaker a and the bluetooth speaker B, for example, a distance between the bluetooth speaker a and the bluetooth speaker B may be obtained, and the signal intensity of the bluetooth speaker B received by the bluetooth speaker a may be determined according to the distance, and if the distance is 10cm, and the signal intensity may be received by the bluetooth speaker a from-20 db to-30 db, the preset intensity threshold may be set to-30 db. After receiving the second Bluetooth connection message, the Bluetooth sound box A can determine whether the signal intensity in the second Bluetooth connection message is greater than-30 db, and if the signal intensity in the second Bluetooth connection message is greater than-30 db, the Bluetooth sound box B is determined to meet the preset Bluetooth connection condition of the Bluetooth sound box A. The bluetooth speaker a may send a bluetooth connection establishment message to the bluetooth speaker B, and the bluetooth speaker B may establish a bluetooth connection with the bluetooth speaker a according to the bluetooth connection establishment message after receiving the bluetooth connection establishment message sent by the bluetooth speaker a.
In addition, if the first bluetooth device does not establish bluetooth connection at the first event execution time and the second event execution time, the first bluetooth device may redetermine a new first event execution time and a new second event execution time, and alternately execute the first bluetooth connection event and the second bluetooth connection event until a preset stop condition is satisfied, and stop alternately executing the first bluetooth connection event and the second bluetooth connection event.
In one possible implementation manner, if the first bluetooth device receives the event stopping instruction, for example, when the first bluetooth device is turned on, if a switch key of the first bluetooth device is triggered, the first bluetooth device is turned off, at this time, the first bluetooth device receives the event stopping instruction, and stops alternately executing the first bluetooth connection event and the second bluetooth connection event.
In another possible implementation, if the first bluetooth device establishes a bluetooth connection with the second bluetooth device, or the first bluetooth device does not establish a bluetooth connection with the second bluetooth device when a preset time is reached, the alternating execution of the first bluetooth connection event and the second bluetooth connection event is stopped. The preset time may be a preset bluetooth connection duration, for example, 3s, 5s, etc., which is not limited in this disclosure.
It should be noted that, before the first bluetooth device alternately executes the first bluetooth connection event and the second bluetooth connection event, the device state of the first bluetooth device may be obtained, and if the first bluetooth device has the second bluetooth device that is successfully paired, the first bluetooth device may directly establish bluetooth connection with the second bluetooth device, without alternately executing the first bluetooth connection event and the second bluetooth connection event.
By adopting the method, after the first Bluetooth device receives the Bluetooth connection request message, the first Bluetooth connection event and the second Bluetooth connection event are alternately executed, and if the Bluetooth connection response message sent by the second Bluetooth device is received under the condition of executing the first Bluetooth connection event, the Bluetooth connection with the second Bluetooth device is established; or under the condition of executing the second Bluetooth connection event, if the second Bluetooth connection message broadcasted by the second Bluetooth device is scanned, establishing Bluetooth connection with the second Bluetooth device according to the second Bluetooth connection message. Thus, since the first bluetooth connection event and the second bluetooth connection event are alternately performed, a bluetooth connection can be established for the same type of bluetooth device; in addition, when establishing bluetooth connection, need not the master-slave identity of fixed bluetooth equipment to the operational complexity when having simplified bluetooth equipment and connected has improved bluetooth connection's speed.
The above bluetooth connection method will be described by taking a bluetooth speaker as an example.
Example one:
As shown in fig. 2, the first bluetooth device is a first bluetooth speaker, the second bluetooth device is a second bluetooth speaker, and after the switch keys of the first bluetooth speaker and the second bluetooth speaker are triggered, the first bluetooth speaker and the second bluetooth speaker can receive a bluetooth connection request message. After receiving the bluetooth connection request message, the first bluetooth speaker may randomly determine an order of executing bluetooth connection events, for example, execute the first bluetooth connection event first, then execute the second bluetooth connection event, and determine that an execution time of the first event for executing the first bluetooth connection event is 1.2s; after receiving the bluetooth connection request message, the second bluetooth speaker may also randomly determine the order of executing the bluetooth connection events, for example, execute the second bluetooth connection event first, then execute the first bluetooth connection event, and determine that the execution time of the first event for executing the second bluetooth connection event is 1s.
If the time that the switch keys of the first Bluetooth sound box and the second Bluetooth sound box are triggered is the same, when the first Bluetooth sound box starts broadcasting the first Bluetooth connection message, the second Bluetooth sound box starts scanning the first Bluetooth connection message at the same time. Because the duration of the second bluetooth speaker for scanning the first bluetooth connection message is 1s, and the duration of the first bluetooth speaker for broadcasting the first bluetooth connection message is 1.2s, the second bluetooth speaker is also always broadcasting the first bluetooth connection message in the process of scanning the first bluetooth connection message, so that the second bluetooth speaker can scan the first bluetooth connection message broadcasted by the first bluetooth speaker. After the second bluetooth speaker scans the first bluetooth connection message broadcasted by the first bluetooth speaker, it may be determined whether the device identifier in the first bluetooth connection message is the same as a device identifier preset by the second bluetooth speaker and allowed to establish bluetooth connection. If the equipment identifier in the first Bluetooth connection message is the same as the preset equipment identifier allowing Bluetooth connection to be established, the second Bluetooth sound box sends a Bluetooth connection response message to the first Bluetooth sound box; if the device identifier in the first bluetooth connection message is different from the device identifier preset by the second bluetooth speaker and allowing bluetooth connection to be established, the second bluetooth speaker can continue to scan the first bluetooth connection message. After the first Bluetooth sound box receives the Bluetooth connection response message sent by the second Bluetooth sound box, bluetooth connection can be established with the second Bluetooth sound box according to the Bluetooth connection response message.
Example two:
As shown in fig. 3, the first bluetooth device is a first bluetooth speaker, the second bluetooth device is a second bluetooth speaker, and after the bluetooth switches of the first bluetooth speaker and the second bluetooth speaker are triggered, the first bluetooth speaker and the second bluetooth speaker receive a bluetooth connection request message. The first bluetooth speaker may acquire a preset execution sequence of the first bluetooth connection event and the second bluetooth connection event, for example, execute the second bluetooth connection event first, then execute the first bluetooth connection event, and then, the first bluetooth speaker may determine that the execution time of the first event for executing the second bluetooth connection event is 1.2s, and determine that the execution time of the second event for executing the first bluetooth connection event is 500ms; the second bluetooth speaker may acquire a preset execution sequence of the first bluetooth connection event and the second bluetooth connection event, for example, execute the second bluetooth connection event first, then execute the first bluetooth connection event, and then, the second bluetooth speaker may determine that the execution time of the first event for executing the second bluetooth connection event is 1s, and determine that the execution time of the second event for executing the first bluetooth connection event is 2s.
If the time that the Bluetooth switch of the first Bluetooth sound box and the second Bluetooth sound box is triggered is the same, when the first Bluetooth sound box starts to scan the second Bluetooth connection message, the second Bluetooth sound box also starts to scan the first Bluetooth connection message. Because the duration of the first bluetooth speaker scanning the second bluetooth connection message is 1.2s, and the duration of the second bluetooth speaker scanning the first bluetooth connection message is 1s, after the duration of the second bluetooth speaker scanning the first bluetooth connection message reaches 1s, the second bluetooth connection message starts to be broadcasted 2s, and at the moment, the first bluetooth speaker also needs to scan the second bluetooth connection message for 200ms, and in the 200ms time period, the first bluetooth speaker can scan the second bluetooth connection message broadcasted by the second bluetooth speaker. After the first Bluetooth sound box scans the second Bluetooth connection message broadcast by the second Bluetooth sound box, whether the equipment information in the first Bluetooth connection message is the same as the preset paired equipment information preset by the second Bluetooth sound box can be determined. For example, if the device name in the preset paired device information is "B sound box", and the device name in the device information in the first bluetooth connection message is also "B sound box", it is determined that the device information in the first bluetooth connection message is the same as the preset paired device information, the first bluetooth sound box may send a bluetooth connection establishment message to the second bluetooth sound box, and after receiving the bluetooth connection establishment message sent by the first bluetooth sound box, the second bluetooth sound box may establish bluetooth connection with the first bluetooth sound box according to the bluetooth connection establishment message.
It should be noted that, if the first bluetooth speaker does not scan the second bluetooth connection message broadcasted by the second bluetooth speaker within 1.2s due to network anomaly or other reasons, the first bluetooth speaker may broadcast the first bluetooth connection message for 500ms. Because the second bluetooth speaker is also broadcasting the second bluetooth connection message all the time within 500ms of the first bluetooth speaker broadcasting the first bluetooth connection message, the first bluetooth speaker and the second bluetooth speaker cannot establish a bluetooth connection. The first bluetooth speaker may redetermine the new first event execution time and the second event execution time and alternately execute the second bluetooth connection event and the first bluetooth connection event.
