Description

Bluetooth pairing control method and device, bluetooth equipment and readable storage medium

Technical Field

The invention relates to the technical field of sound box control, in particular to a Bluetooth pairing control method and device, bluetooth equipment and a readable storage medium.

Background

With the development of Wireless communication technology and the increasing demand of people for Wireless audio devices, more and more separated Wireless Stereo (TWS) bluetooth devices have come into play. Taking the TWS bluetooth speaker as an example, the main speaker is connected to the mobile phone in a bluetooth wireless manner, and the slave main speaker is connected to the slave speaker in a bluetooth wireless manner. One of the sound boxes is a left sound channel, and the other sound box is a right sound channel, so that the real Bluetooth wireless separation of the left sound channel and the right sound channel is realized to play stereo sound. When the slave enclosure is not connected, the master enclosure returns to mono stereo. The conventional pairing procedure for the bluetooth TWS speaker generally includes the following steps:

1: a user turns on the Bluetooth master loudspeaker box and the Bluetooth slave loudspeaker box;

2: the mobile phone is matched with the Bluetooth main sound box;

3: the master loudspeaker box and the slave loudspeaker boxes are in a power-off state, and the appointed keys of the master loudspeaker box and the slave loudspeaker boxes are pressed for about 10 seconds at the same time until the appointed prompt is received;

4: the main loudspeaker box and the auxiliary loudspeaker box enter a TWS pairing state, and the main loudspeaker box searches for the auxiliary loudspeaker box or the auxiliary loudspeaker box searches for the main loudspeaker box;

5: after about 3 seconds, the master loudspeaker searches the slave loudspeaker, and the Bluetooth TWS is successfully paired;

6: after the master and slave sound boxes are successfully connected, the mobile phone is powered on after being powered off, and the master sound box is automatically connected back to the mobile phone.

So far, the user can use the bluetooth TWS speaker to play the audio data of the mobile phone terminal. However, the conventional bluetooth TWS pairing method is only applicable to those familiar with TWS pairing methods. The master device and the slave device need to press a designated key for the same time in the shutdown state, and the two devices are restarted after the TWS pairing is successful. The key pressing time is not easy to control, the operation process is complex, the pairing time is long, and the user experience is influenced to a great extent. Therefore, a simple and fast pairing method for the bluetooth TWS equipment is needed, which brings convenience to users and improves the experience effect of the bluetooth TWS audio product.

Referring to fig. 1, a schematic diagram of an implementation flow of a bluetooth pairing control method provided in an embodiment of the present invention is shown, where the method includes:

s11: when a starting-up instruction of target equipment is detected, setting an NFC module of the target equipment into an analog card mode;

in this embodiment, an execution main body of the bluetooth pairing control method is a pairing control device, the pairing control device may be a bluetooth device body, or may be a terminal device independent of the bluetooth device, and the terminal device may be a mobile phone, a notebook computer, a tablet computer, a server, or the like. In this embodiment, a bluetooth device body is taken as an example of the pairing control apparatus. The bluetooth device may be a bluetooth speaker or a bluetooth headset.

When two Bluetooth devices realize TWS pairing, one Bluetooth device serves as a master device, and the other Bluetooth device serves as a slave device. The main device and the slave device are in TWS pairing, and simultaneously are in Bluetooth connection with the sound source device to acquire audio data output by the sound source device and transmit the audio data to the slave device. The bluetooth device can be a bluetooth headset, a bluetooth speaker or other devices with playing and bluetooth functions. The sound source device can be a mobile terminal person such as a mobile phone or a sound source device with an NFC function and a Bluetooth function, and the NFC initial state of the sound source device is a card reader state.

In this embodiment, the target device is a bluetooth device, and includes an NFC module and a bluetooth module, where the NFC module is used to transmit near field data with other devices, and the bluetooth module is used to perform bluetooth communication with other devices. And the NFC module is in communication connection with the Bluetooth module. The target device further comprises a processor, preferably integrated on the bluetooth module, and communicating with the NFC via the bluetooth module. When the processor detects a starting instruction of the target device, the NFC module of the target device is set to be in an analog card mode, the NFC module in the analog card mode can communicate with the NFC module in the card reader module, and when the opposite-end device with the NFC module of the card reader module is close to the target device, the target device can detect the opposite-end device and communicate with the opposite-end device through the NFC module.

S12: when the NFC module is detected to be in a communication state, acquiring a pairing request instruction sent by first pairing equipment through the NFC module, and judging whether the first pairing equipment is sound source equipment or main equipment according to the pairing request instruction;

in this embodiment, when the processor of the target device detects that the NFC module of the target device is in a communication state, the processor of the target device obtains a pairing request instruction sent by the peer device through the NFC module, where the peer device is the first pairing device. It should be noted that, since the NFC module is in the analog card mode, the paired device in NFC communication with the target device should have the NFC module in the card reader module. When the NFC module of the first pairing device is communicated with the NFC module of the target device, the first pairing device sends a pairing request instruction to the NFC module of the target device through the NFC module. When the target device detects that the NFC module is in a communication state, the target device acquires a pairing request instruction sent by the first pairing device through the NFC module.

And after the pairing request instruction is acquired, judging whether the first pairing equipment is sound source equipment or main equipment according to the pairing request instruction. The master device is a device having a role as a master device in the TWS pairing system, and the slave device is a device having a role as a slave device in the TWS pairing system. Optionally, the pairing request instruction includes a pairing request and a device type, where the pairing request is used to inform the target device of a request purpose of the first pairing device, and the device type is used to inform the target device of whether a role of the first pairing device is an audio source device or a master device in the TWS pairing system. At this time, the processor determines whether the first pairing device is the sound source device or the master device according to the device type in the pairing request instruction.

Or, the pairing request includes a common pairing request and a TWS pairing request, and when the first pairing device is an audio source device, the pairing request sent by the first pairing device is the common pairing request, and when the first pairing device is a master device, the pairing request sent by the first pairing device is the TWS pairing request. At this time, the processor determines whether the pairing request is a normal request instruction or a TWS pairing request instruction, and if the pairing request is the normal request instruction, it indicates that the first pairing device is the sound source device, and if the pairing request is the TWS pairing request instruction, it indicates that the first pairing device is the master device.

The TWS pairing request instruction includes an identification type of the first pairing device, and the identification type includes a master device identification and a slave device identification. The master device identification indicates that the role of the first pairing device in the TWS pairing system is a master device, and the slave device identification indicates that the role of the first pairing device in the TWS pairing system is a slave device.

S13: when the first pairing device is judged to be the sound source device, setting a Bluetooth module of the target device to be in a Bluetooth pairing mode, and sending pairing data of the Bluetooth module to the sound source device through the NFC module so as to enable the target device and the sound source device to be paired;

and when the first pairing equipment is judged to be the sound source equipment, establishing pairing with the sound source equipment according to the pairing request instruction. In this embodiment, the bluetooth module includes a bluetooth pairing mode and a TWS pairing mode, the bluetooth pairing mode is used for pairing and connecting with the audio source device, and the TWS pairing mode is used for forming a TWS pairing system with another bluetooth device.

When the first pairing device is judged to be the sound source device, the Bluetooth module of the target device is set to be in a Bluetooth pairing mode, and the pairing data of the Bluetooth module is sent to the sound source device through the NFC module. The pairing data includes a bluetooth address and a bluetooth device name. After the sound source equipment acquires the pairing data of the Bluetooth equipment through the NFC module, the Bluetooth function is automatically started, and pairing is established with the target equipment.

S14: setting the NFC module into a card reader mode, and updating the target device as a master device identifier;

after the target device and the sound source device are connected in a pairing mode, the target device serves as a master device in the TWS pairing system, and the TWS pairing can be achieved only after the master device and the slave device are paired. Since the NFC module of the slave device is in the analog card mode at the initial stage, to establish the NFC communication connection between the slave device and the host device, the NFC module of the host device needs to be set to the card reader mode. And after the target equipment and the sound source equipment are connected in a pairing mode, setting the NFC module into a card reader mode, and detecting the communication state of the NFC module. When the slave device approaches, the target device communicates with the NFC module of the slave device, so that the master device detects that the NFC module is in communication. Meanwhile, the target device is also updated to be the main device identification so as to inform the role type of the target device of the opposite terminal device in NFC communication with the target device.

S15: and when the first pairing device is judged to be the main device, setting the Bluetooth module to be in a TWS pairing searchable mode, so that the target device and the main device realize TWS pairing.

In the present embodiment, the TWS pairing mode includes a TWS pairing searchable mode and a TWS pairing search mode. When the Bluetooth module of the target device is in the TWS pairing searchable mode, the role of the target device as the slave device in the TWS pairing is described, and when the Bluetooth module of the target device is in the TWS pairing search mode, the role of the target device as the master device in the TWS pairing is described.

When the NFC module of the target device is in the analog card mode, the target device may perform NFC communication with the NFC module of the sound source device, and at this time, the target device serves as a master device in the TWS pairing system. The target device may also perform NFC communication with a master device in which the NFC module is in a card reader mode, where the target device serves as a slave device in the TWS pairing system.

The pairing request instruction sent by the master device includes an identifier type or a device type of the master device, and when the identifier type or the device type indicates that the first pairing device is the master device, it may be determined that the first pairing device is the master device. When the pairing device is judged to be the master device, the Bluetooth module of the target device is set to be in the TWS pairing searchable mode, the Bluetooth module of the master device is in the TWS searching module mode, and when the master device searches the slave device, the TWS pairing connection between the slave device and the master device can be achieved.

And after the target device and the first pairing device realize TWS pairing, updating the target device as a slave device identifier.

In this embodiment, the target device may perform audio data communication connection with the sound source device as a master device in the TWS pairing system, and may also perform TWS pairing connection with the master device as a slave bluetooth device in the TWS pairing system. Meanwhile, the target equipment serving as the master equipment and the slave equipment can be connected in a TWS pairing mode by switching the modes of the NFC modules, the automatic TWS pairing connection of the master equipment and the slave equipment can be realized only by enabling the sound source equipment, the master equipment and the slave Bluetooth equipment to be close to each other by a user in the whole process, and the TWS pairing process of the target equipment is greatly simplified.

Referring to fig. 2, it is a schematic diagram of an implementation flow of a bluetooth pairing control method according to a second embodiment of the present invention, including S21 to S27, where S21 to S25 are the same as S11 to S15, and are not described herein again, but different from S24, the bluetooth pairing control method further includes S26 and S27, which are detailed as follows:

s26: when the NFC module is detected to be in a communication state, setting the Bluetooth module to be in a TWS pairing search mode, and sending a pairing request instruction to second pairing equipment through the NFC module, wherein the pairing request instruction comprises the main equipment identification, so that the second pairing equipment sets the Bluetooth module of the second pairing equipment to be in a TWS pairing searchable mode according to the pairing request instruction;

in this embodiment, by switching the mode of the NFC module, the target device as the master device and the slave device may perform TWS pairing connection. At this time, the NFC module of the target device is in the card reader mode, and the NFC module of the second pairing device is in the analog card mode. When the target device and the second pairing device are within the communication range of the NFC module, the NFC module of the target device and the NFC module of the second pairing device establish communication.

And the processor of the target device detects that the NFC module is in a communication state, sets the Bluetooth module into a TWS pairing search mode, and sends a pairing request instruction to the slave device through the NFC module. And the second pairing equipment acquires that the opposite side is the main equipment according to the pairing request instruction, and the request content is a TWS pairing request. After receiving the pairing request command, the second pairing device performs step S15 to set the bluetooth module to the TWS pairing checkable mode. At this time, the second pairing device is a bluetooth device, such as a bluetooth speaker, a bluetooth headset, or the like.

S27: searching for the second paired device in a TWS pairing searchable mode to enable TWS pairing of the target device with the second paired device.

And after the target device sends a pairing request instruction through the NFC module, searching for second pairing equipment in a TWS pairing searchable mode, and when the second pairing equipment in the TWS pairing searchable mode is searched, establishing TWS pairing with the second pairing equipment.

In this embodiment, after switching the mode of the NFC module, when it is detected that the NFC module is communicating, the target device may quickly establish a TWS pairing connection with a second pairing device as a slave device as a master device, so as to reduce user operations.

In other embodiments, when the NFC module is not detected to be in the communication state within a preset time, a target device is utilized to perform monaural audio playing.

Referring to fig. 3, it is a schematic diagram of a process for implementing a bluetooth pairing control method according to the third embodiment of the present invention, including S31 to S37, where S31, S34 to S38 are the same as S21, S23 to S27, and are not described herein again, but the difference is that S32 and S33 are included after S31, where S33 is the same as S22, and are not described herein again. The details are as follows:

s32: when the GPIO pin detects that hardware interruption is generated due to the change of the level of the magnetic field detection pin, the NFC module is judged to be in a communication state, a pairing request instruction of a first pairing device is acquired from the NFC module through the communication connection between the Bluetooth module and the NFC module,

s33: judging whether the first pairing equipment is sound source equipment or main equipment according to the pairing request instruction;

in this embodiment, the target device includes an NFC module and a bluetooth module, the NFC module includes a magnetic field detection pin, the bluetooth module includes a GPIO pin, and the magnetic field detection pin of the NFC module is connected to the GPIO pin of the bluetooth module. When one NFC module in an analog card mode detects the magnetic field of the other NFC module in a card reader mode, NFC communication occurs by double sending, and the level of each magnetic field detection pin can change at the beginning of communication. After receiving the level change, the GPIO pin of the Bluetooth module generates hardware interrupt and delivers the hardware interrupt to the processor for processing so as to awaken the Bluetooth module to enter a pairing mode. In this embodiment, when the GPIO pin detects a hardware interrupt caused by a level change of the magnetic field detection pin, it is determined that the NFC module is in a communication state.

In this embodiment, the bluetooth module is in communication connection with the NFC module, and preferably, the bluetooth module is in serial communication connection or I2C communication connection with the NFC module. The NFC module is responsible for communicating with opposite-end NFC equipment, and the Bluetooth module is responsible for processing data, calculating and receiving and transmitting Bluetooth data.

In this embodiment, when the GPIO pin detects that hardware interrupt occurs due to a change in level of the magnetic field detection pin, it is determined that the NFC module is in a communication state, and a pairing request instruction sent by a first pairing device is read through communication connection between the bluetooth module and the NFC module. And judging that the NFC module is in a communication state when hardware interruption is generated due to the fact that the GPIO pin detects the level change of the magnetic field detection pin, and awakening the Bluetooth module to enter a pairing state.

In a preferred embodiment, in the step: when the power-on instruction is detected, the method further includes, after setting the NFC module to the analog card mode: and presetting the level of the GPIO pin of the Bluetooth module. Preferably, the NFC module is set to the emulated card mode by sending an emulated card initialization command to the NFC module. And simultaneously, the level of a GPIO pin connected with a magnetic field detection pin of the NFC module is pulled high. The level of the GPIO pin of the Bluetooth module is pulled high, the magnetic field detection pins of the two communication parties are changed from high level to low level when the NFC module starts to communicate, and hardware interruption is generated after the GPIO pin detects the high-low change. And automatically returning to the high level after the NFC communication is finished.

In another embodiment, the steps of: through the NFC module to the pairing data of sound source equipment transmission bluetooth module, include: sending pairing data of the Bluetooth module to the NFC module through communication connection between the Bluetooth module and the NFC module; and the NFC module sends the pairing data to an NFC module of the sound source equipment.

The method comprises the following steps: sending a pairing request instruction to a slave target device through the NFC module, wherein the pairing request instruction comprises: sending a pairing request instruction to the NFC module through the communication connection between the Bluetooth module and the NFC module; and the NFC module sends the pairing request instruction to the NFC module of the slave target device.

In this embodiment, the NFC module itself does not store data, and the wireless data sent by the NFC module is sent to the NFC module by the bluetooth module through the communication connection, and then sent to the NFC module of the opposite end by the NFC module wireless transceiver. And the data transmitted by the opposite-end NFC module received by the NFC module is also sent to the Bluetooth module for processing through communication connection. The NFC module can be initialized to a card reader mode or an analog card mode by a corresponding command, which is sent by the bluetooth module to the NFC module via the communication connection.

The pairing data and the pairing request command are both transmitted to the NFC module by the Bluetooth module, and the NFC module does not store data and is only responsible for communication.

Referring to fig. 4, it is a schematic diagram of a process for implementing a bluetooth pairing control method according to a fourth embodiment of the present invention, including S41 to S48, where S45 to S48 are the same as S11 to S15, and are not described herein again, except that S11 includes S41 to S44, which are detailed as follows:

s41: when a starting-up instruction is detected, judging whether a TWS pairing history exists or not;

in this embodiment, the bluetooth device will keep the last TWS pairing history in the history table. The information in the history table includes pairing information of the paired devices, a role type (master device or slave device), and the like. When a power-on instruction is detected, it is first determined whether there is a TWS pairing history.

S42: searching for a third pairing device corresponding to a TWS pairing history when the TWS pairing history exists;

and when the TWS pairing history exists, searching a corresponding third pairing device according to the TWS pairing history. Specifically, whether the third pairing device is a master device or a slave bluetooth device is determined according to the TWS pairing history. The role type in the history table includes a master device or a slave device, and when the role type in the history table is the master device, it indicates that the target device is the master device, and the third paired device is the slave device, and when the role type in the history table is the slave device, it indicates that the target device is the slave device, and the third paired device is the master device. Different role types correspond to different modes of the bluetooth module. And when the role type of the target device is the master device, namely the third pairing device is the slave device, setting the Bluetooth module of the target device to be in a TWS pairing search mode, and when the role type of the target device is the slave device, namely the third pairing device is the master device, setting the Bluetooth module of the target device to be in a TWS pairing searchable mode.

For example, if the role type is recorded as the master device in the history table, the bluetooth module of the target device is set to the TWS pairing search mode, and if the role type is recorded as the slave device in the history table, the bluetooth module of the target device is set to the TWS pairing searchable mode.

S43: when the third pairing device is searched within the preset time, completing TWS pairing with the third pairing device;

when the third pairing device is searched in the preset time, it is described that the bluetooth mode of the third pairing device is also set correspondingly in the preset time period. For example, if the target device is in the TWS pairing search mode, the third pairing device is in the TWS pairing searchable mode, and the pairing information of the third pairing device corresponds to the history table, the pairing is established with the third pairing device. It will be appreciated that when the pairing information of the third paired device does not correspond to the history table, then no pairing can be established, for example the name of the third paired device does not correspond to the name recorded in the history table.

S44: when the third pairing device is not searched within a preset time or when there is no TWS pairing history, performing the steps of: the NFC module is set to an analog card mode.

When the third pairing device is not searched within the preset time, it indicates that the third pairing device is not in the use time period and cannot be used, or when there is no TWS pairing history, it indicates that the target device is paired for the first time, then the following steps are executed: and setting the NFC module to be in an analog card mode so as to carry out pairing connection of TWS (two way communication) on the target device and other pairing devices.

In this embodiment, when there is a TWS pairing history, the TWS connection between the master device and the slave bluetooth device is directly and automatically implemented according to the history pairing condition, and the master, slave bluetooth devices, and sound source devices do not need to be brought close to each other for re-pairing, which can reduce the pairing process and speed up the pairing progress.
