In the above apparatus, the first bluetooth device 1 and the second bluetooth device 2 are made to simultaneously generate vibrations, then the first bluetooth module 10 generates a first device name and a first PIN code according to a vibration signal acquired by the first vibration sensor 11, and then broadcasts the first device name and the first PIN code to the second bluetooth module 20, and at the same time, the second bluetooth module 20 generates a second device name and a second PIN code according to a vibration signal acquired by the second vibration sensor 21, and then the second bluetooth module 20 verifies the device names and the PIN codes of the two bluetooth devices, and only when the first device name is consistent with the second device name and the first PIN code is consistent with the second PIN code, the second bluetooth module 20 establishes a bluetooth connection with the first bluetooth module 10. Compared with the prior art, the device name and the PIN code are generated by simultaneously collecting and processing the vibration signals, and the built-in algorithms of the first Bluetooth device 1 and the second Bluetooth device 2 are the same, so that the Bluetooth connection can be quickly established as long as the vibration signals sensed by the first Bluetooth device and the second Bluetooth device are synchronous and consistent.
Preferably, the vibration signal includes a vibration frequency, a time point at which vibration occurs, and a vibration intensity. Further, the time interval between two vibrations is not more than 2 seconds. But the vibration signal is not limited in the practical application process, and the vibration signal can be set to other types according to the practical requirement.
In this embodiment, the first vibration sensor 11 and the second vibration sensor 21 are both gyroscopes. Of course, the vibration sensor used in the present invention is not limited to a gyroscope, and even if the vibration sensor is replaced by another sensor capable of collecting vibration, the present invention should also fall into the protection scope of the present invention.
In order to better describe the technical solution of the present invention, the present invention further relates to a bluetooth device fast connection method, please refer to fig. 1, which is implemented based on an apparatus, the apparatus includes a first bluetooth device 1 and a second bluetooth device 2, the first bluetooth device 1 includes a first bluetooth module 10 and a first vibration sensor 11, the second bluetooth device 2 includes a second bluetooth module 20 and a second vibration sensor 21, and the method includes the following steps:
step S1, making the first bluetooth device 1 and the second bluetooth device 2 generate vibration at the same time;
step S2, the first vibration sensor 11 senses a vibration signal and transmits it to the first bluetooth module 10 in the form of an electrical signal, and then step S3 is performed;
meanwhile, the second vibration sensor 21 senses a vibration signal and transmits the vibration signal to the second bluetooth module 20 in the form of an electrical signal, and then step S4 is performed;
step S3, the first bluetooth module 10 obtains a vibration signal collected by the first vibration sensor 11, and when the vibration signal meets a preset vibration condition, generates a first device name and a first PIN code according to the vibration signal, and broadcasts a wireless signal including the first device name and the first PIN code;

step S6, the second bluetooth module 20 establishes a bluetooth connection with the first bluetooth module 10 only when the first device name is consistent with the second device name and the first PIN code is consistent with the second PIN code.
In step S1 of the method, the first bluetooth device 1 and the second bluetooth device 2 are made to generate vibration simultaneously by colliding with each other. However, in practical applications, the two bluetooth devices are not limited to collide with each other, for example, when the two bluetooth devices are placed on the same table surface in a close range, the table surface can be regularly knocked, and at this time, the two bluetooth devices can sense vibration and realize bluetooth connection.
Further, in step S2, the vibration signal includes the number of vibrations, the time point of the vibration and the strength of the vibration, and the time interval between the two vibrations is not greater than 2 seconds.
In this embodiment, in step S1, before the first bluetooth device 1 and the second bluetooth device 2 collide with each other, the first bluetooth device 1 and the second bluetooth device 2 are set to a bluetooth on state. In the Bluetooth starting state, the two Bluetooth devices can be ensured to accurately establish Bluetooth communication.
In a preferable mode, in the steps S3 and S4, "vibration occurrence date + vibration intensity" or "date + hours + 01" is used as the device name. Further, in the steps S3 and S4, "vibration occurrence time point + vibration intensity" or "vibration occurrence time point + 0001" is used as the PIN code.
For the algorithm for generating the device name and PIN code, please see the following example:
example 1, taking a smart watch as an example, when a user taps another bluetooth device while wearing the smart watch, for example, three taps at times of 2020/4/27 days 17:00:00 seconds for the first time, 2020/4/27 days 17:00:03 seconds for the second time, 2020/4/27 days 17:00:05 seconds for the third time, the second time being higher than the first time and the third time being lower than the second time; according to the date + vibration intensity algorithm, the method comprises the following steps: 04273123, (where 0427 is date, 3 indicates three taps, 123 indicates that the intensity of the first, second, and third taps is gradually increased, and 123 is three taps with the strongest intensity), the algorithm according to time point + vibration intensity is analyzed as: 170323, (where 17 is the time point, 03 means three vibrations, 23 means the third, second, two taps with the weakest intensity, and the third is weaker than the second);
example 2, when the user taps once, with the date + hours +01 as the device name and the time point +0001 as the PIN, such as 2020/4/27 days 17:00:00, then 04271701 is the device name and 170001 is the PIN code.
The above two examples are only for better illustrating the technical solution of the present invention, and do not specifically limit the present invention, and similarly, the present invention may also adopt other code generation manners in practical application, and the specific PIN code length is not limited to 6 bits, and may also be other bits such as 4 bits, 8 bits, and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the technical scope of the present invention should be included in the scope of the present invention.
