Detailed ways

Please refer to FIG. 1. FIG. 1 is one of the schematic flowcharts of the Bluetooth pairing connection method provided by Embodiment 1 of the present invention. The method is applied to Bluetooth devices, including:

Step 11: sending a broadcast data packet externally, the broadcast data packet including the address information of the Bluetooth device;

Wherein, the address information of the Bluetooth device uniquely corresponds to the Bluetooth device. The uniqueness of the address information of the bluetooth device enables the terminal to determine which bluetooth device to automatically connect with.

Step 12: Generate a paired carrier signal based on the address information of the Bluetooth device, the wake-up identification code and the preset carrier signal;

Wherein, the preset carrier signal may be an electromagnetic wave signal or an acoustic wave signal. The wake-up identification code is used to instruct the terminal to turn on the bluetooth, and is confirmed through negotiation between the terminal and the bluetooth device. The paired carrier signal is used for the terminal to turn on Bluetooth when it recognizes the wake-up identification code.

Step 13: Send the paired carrier signal externally.

Wherein, the paired carrier signal is used for the terminal to determine whether it is compatible with the Bluetooth device according to the address information of the Bluetooth device in the broadcast data packet and the address information of the Bluetooth device in the paired carrier signal when Bluetooth is turned on. pairing with the Bluetooth device mentioned above.

The Bluetooth pairing and connection method provided by the embodiment of the present invention enables the terminal to automatically determine whether to pair and connect with the Bluetooth device by sending broadcast data packets and pairing carrier signals, without manual operation by the user. user's time.

In the above embodiment, the bluetooth device may be a bluetooth headset, a bluetooth speaker, or a car bluetooth.

Due to the low energy consumption of sound waves, and in sound waves of different frequencies, audible sound wave signals will cause sound pollution, there are many sound sources in audible sound wave signals, and there will be greater interference; It has strong directivity, and there are blind spots in the propagation process, which makes the receiving end unable to receive.

Therefore, preferably, the preset carrier signal is a preset infrasonic carrier signal.

Therefore, the generated paired carrier signal is an infrasound wave signal, which will not cause sound interference during transmission, has a better transmission effect, and saves more energy consumption.

The frequency of the preset infrasonic carrier signal in the embodiment of the present invention is less than 20 Hz. The frequency of the preset infrasonic carrier signal can be set according to actual needs, which is more flexible and convenient.

In some preferred embodiments of the present invention, the wake-up identification code for instructing the terminal to turn on Bluetooth can be set by itself according to actual needs, but it must be a wake-up identification code that is uniformly approved by both the Bluetooth device and the terminal, so that Bluetooth can be realized. Automatic pairing connection between device and terminal.

Preferably, the wake-up identification code used to instruct the terminal to turn on Bluetooth is uniquely corresponding to both the Bluetooth device and the terminal. Therefore, when pairing and connecting between the terminal and the Bluetooth device, the workload can be reduced, the response can be faster, and the energy consumption can be saved more.

For example, the wake-up identification code between the mobile phone A and the Bluetooth headset a of the same series is "A_open_Bluetooth", and the wake-up identification code "A_open_Bluetooth" only corresponds to the mobile phone A and the Bluetooth headset a of the same series. Therefore, when the mobile phone A of this series and the Bluetooth headset a are paired and connected, the connection efficiency can be further improved.

In the embodiment of the present invention, multiple ways can be used to generate the paired carrier signal.

As one of the preferred specific implementations, the step of generating the paired carrier signal includes: generating an original signal based on the address information and the wake-up identification code of the Bluetooth device; loading the original signal on the carrier of the Bluetooth device The preset infrasound carrier signal sent by the signal generator generates a synthetic sound wave signal; the synthetic sound wave signal is amplified to generate a paired carrier signal.

Specifically, the carrier signal generator of the Bluetooth device sends out the preset infrasonic carrier signal P1#; according to the address information #Address_01 of the Bluetooth device and the wake-up identification code used to instruct the terminal to turn on Bluetooth, the original signal P2# is generated; the carrier signal P1# and the original signal P2# are re-encoded and converted, and the original signal P2# is loaded on the carrier signal P1# to generate a synthetic sound wave signal P3#; the synthetic sound wave signal P3# is amplified to generate a paired carrier signal P3_1#.

Therefore, the existing components and parts of the Bluetooth device are used to generate the paired carrier signal without increasing the cost of the Bluetooth device.

With the popularization of smart terminals and Bluetooth devices, terminals and Bluetooth devices are everywhere in the living space. In order to reduce the workload of terminals and Bluetooth devices and improve the efficiency of pairing and connection, in the embodiment of the present invention, Bluetooth devices can be set to The terminal's distance is less than or equal to the specified distance threshold. According to the attenuation relationship of the sound pressure level of the infrasound wave signal propagating in space, it can be determined that when the distance between the Bluetooth device and the terminal is less than or equal to the specified distance threshold, the sound pressure level attenuation of the infrasound wave is less than or equal to the preset threshold.

Therefore, preferably, the sound pressure level of the paired carrier signal is higher than the sound pressure level of the environment where the Bluetooth device is currently located, and the sound pressure level of the paired carrier signal is higher than the sound pressure level of the environment where the Bluetooth device is currently located. The difference in pressure levels is less than or equal to a preset threshold. Therefore, when the terminal receives the pairing carrier signal sent by the Bluetooth device whose distance to the terminal is less than or equal to the specified distance threshold, the workload of the terminal is greatly reduced, and the efficiency of the pairing connection is improved.

Preferably, the sound pressure level of the current environment where the Bluetooth device is located is obtained by a microphone module of the Bluetooth device. The sound pressure level of the current environment where the Bluetooth device is located is obtained through the existing microphone module of the Bluetooth device, and the Bluetooth device does not need to increase the hardware and the cost of the Bluetooth device.

For example, the specified distance threshold is 50 cm, and when the distance between the Bluetooth device and the terminal is less than or equal to 50 cm, the sound pressure level attenuation of the infrasonic wave is less than or equal to 10 dm. In the embodiment of the present invention, it can be set that the energy requirement of the paired carrier signal P3_1# is 10dB higher than the background noise of the environment where the Bluetooth device is located, and the background noise of the current environment where the Bluetooth device is obtained by analyzing the microphone module of the Bluetooth device The sound pressure level is denoted as Lp, and the sound pressure level of the paired carrier signal P3_1# can be set as Lp+10dB.

In some preferred embodiments of the present invention, after the step of sending the pairing carrier signal, the method further includes: receiving a pairing instruction sent by the terminal; and performing a pairing connection with the terminal. Therefore, after receiving the pairing instruction, the Bluetooth device can immediately perform pairing and connection with the terminal without manual operation by the user, and the response is more sensitive and the connection is faster.

Wherein, the pairing instruction sent by the terminal is generated when the terminal determines to perform a pairing connection with the Bluetooth device.

That is to say, when the terminal determines to perform a pairing connection with the Bluetooth device, it will send a pairing instruction to the corresponding Bluetooth device, and the Bluetooth device receives the pairing instruction and performs a pairing connection with the terminal.

Please refer to FIG. 2. FIG. 2 is one of the schematic flowcharts of the Bluetooth pairing and connection method provided in Embodiment 2 of the present invention. The method is applied to a Bluetooth device, including:

Step 21: Receive the pairing carrier signal sent by the Bluetooth device, the pairing carrier signal includes the address information of the Bluetooth device, the wake-up identification code and the preset carrier signal;

Wherein, the paired carrier signal may be an electromagnetic wave signal or an acoustic wave signal. The address information of the Bluetooth device uniquely corresponds to the Bluetooth device sending the address information. The uniqueness of the address information of the bluetooth device enables the terminal to determine which bluetooth device to automatically connect with. The wake-up identification code used to instruct the terminal to turn on the Bluetooth is confirmed through negotiation between the terminal and the Bluetooth device.

Step 22: Turn on the Bluetooth switch based on the paired carrier signal, and store the address information of the Bluetooth device;

When the terminal recognizes the wake-up identification code, it turns on the Bluetooth switch; when it detects the address information of the Bluetooth device, it stores the address information.

Step 23: Receive a broadcast data packet, the broadcast data packet includes the address information of the Bluetooth device;

Step 24: When the address information of the Bluetooth device in the broadcast data packet matches the address information of the stored Bluetooth device, send a pairing instruction to the Bluetooth device that sent the broadcast data packet, and match with the Bluetooth device sent by the broadcast data packet. The Bluetooth device that broadcasts the data packet mentioned above is paired and connected.

That is, the terminal matches the address information of the Bluetooth device in the broadcast data packet received in step 23 with the address information of the stored Bluetooth device, and when the same address information is matched, it determines that the Bluetooth device corresponding to the address information It is the Bluetooth device to be paired and connected, outputting a pairing instruction, and performing a pairing connection with the Bluetooth device sending the broadcast data packet.

The Bluetooth pairing and connection method provided by the embodiment of the present invention can automatically judge whether to pair and connect with the Bluetooth device by receiving the broadcast data packet and the paired carrier signal, without manual operation by the user, which is highly intelligent, more convenient and faster, and saves the user's time time.

Preferably, the preset carrier signal is a preset infrasonic carrier signal.

That is to say, the paired carrier signal is an infrasonic signal, which will not cause sound interference during transmission, has a better transmission effect, and saves energy consumption.

Preferably, the frequency of the preset infrasonic carrier signal is less than 20 Hz.

In the embodiment of the present invention, multiple methods may be used to detect the paired carrier signal.

As one of the preferred specific implementation manners, the turning on the Bluetooth switch based on the paired carrier signal includes: decoding the paired carrier signal to restore the original signal, the original signal including the address of the Bluetooth device Information and wake-up identification code; when the wake-up identification code in the original signal is identified, turn on the Bluetooth switch; wherein, when the Bluetooth switch is turned on, the terminal can receive the broadcast data packet sent by the Bluetooth device.

Therefore, by decoding the paired carrier signal, the terminal can automatically turn on the Bluetooth switch when it recognizes the wake-up identification code in the original signal, without manual operation by the user, which is simple and convenient, and also helps to save energy consumption of the terminal.

Further, before decoding the paired carrier signal and restoring the original signal, the method further includes: filtering the audible sound wave signal and the ultrasonic wave signal in the current environment where the terminal is located.

That is to say, the infrasonic signal is obtained by filtering the audible sound wave signal and the ultrasonic signal, thereby reducing the interference signal in the paired carrier signal, reducing the workload of the terminal, and further saving the energy consumption of the terminal.

Specifically, the terminal receives the paired carrier signal P3_1# sent by the Bluetooth device, analyzes the paired carrier signal P3_1#, first filters out the audible sound wave signal and the ultrasonic signal in the environment, and obtains the infrasound wave signal; Frequency (for example: 10Hz), corresponding to the obtained synthetic sound wave signal P3#; re-decode the synthetic sound wave signal P3# to restore the original signal P2#; then analyze the original signal P2#, and identify the In the case of the Bluetooth wake-up identification code (for example: "sn_open_Bluetooth"), turn on the Bluetooth switch of the terminal, and at the same time, when the address information #Address_01 of the Bluetooth device is detected, store the address information #Address_01; after the terminal turns on Bluetooth, Receive the broadcast data packets sent by the Bluetooth devices near the terminal, and these broadcast data packets carry the address information of the Bluetooth devices that sent the broadcast data packets; decode the received broadcast data packets, and check out the address information of the Bluetooth devices in the broadcast data packets The address information is matched and analyzed with the stored address information of the Bluetooth device; when the same address information is matched, a pairing instruction is sent to automatically pair and connect with the Bluetooth device corresponding to the address information.
