Referring to fig. 1, an embodiment of the present application provides a bluetooth connection method for connecting a bluetooth terminal and a designated bluetooth device, where bluetooth address information of the designated bluetooth device is encrypted by a designated encryption algorithm, and the bluetooth terminal has a decryption algorithm corresponding to the designated encryption algorithm, including the steps of:
s1, judging whether a Bluetooth connection instruction is received;
s2, if receiving a Bluetooth connection instruction, monitoring sound information of the current environment;
s3, decrypting the sound information to obtain the Bluetooth address information;
and S4, connecting the appointed Bluetooth equipment according to the decrypted Bluetooth address information.
The bluetooth terminal refers to a terminal with a bluetooth function, such as a bluetooth mobile phone, a bluetooth tablet computer, a bluetooth desktop computer, a bluetooth notebook computer, and the like. The bluetooth device refers to a device having a bluetooth function, such as a bluetooth mobile phone, a bluetooth tablet, a bluetooth desktop, a bluetooth notebook, a bluetooth headset, a bluetooth speaker, and the like. The Bluetooth equipment has an encryption algorithm, can encrypt the Bluetooth address information of the Bluetooth equipment and sends the information out in a sound mode. Correspondingly, the Bluetooth terminal has a corresponding decryption algorithm, and after receiving the encrypted Bluetooth address information sent in the form of voice, the Bluetooth terminal can decrypt the encrypted Bluetooth address information to obtain the Bluetooth address information.
Step S1 is performed to determine whether a bluetooth connection command is received. The bluetooth connection instruction can be generated by selecting a bluetooth connection option on a screen through a finger, or can be generated through a key or a key combination of a bluetooth terminal (such as a bluetooth terminal with keys, such as a bluetooth mobile phone, a bluetooth tablet computer, a bluetooth desktop computer, a bluetooth notebook computer, and the like); or receiving a Bluetooth connection instruction required by the APP after the APP is opened; or may be a bluetooth connection command generated by other means.
And step S2, if receiving the bluetooth connection command, monitoring the sound information of the current environment. The sound is monitored by a sound collection device (sound input device). The sound collection device (sound input device) may be a microphone or a microphone array. The sound collection device (sound input device) can be always turned on (no matter the Bluetooth terminal is in a standby state or a working state), and can also be turned on according to an instruction according to needs.
And step S3, decrypting the sound information to obtain the bluetooth address information. As mentioned above, the bluetooth device has an encryption algorithm, and can encrypt the bluetooth address information of the bluetooth device and send out the encrypted bluetooth address information in the form of sound. When the monitored sound contains the encrypted Bluetooth address information, the sound is indicated to contain the required information and is further processed. Wherein the sound containing the encrypted bluetooth address information of the bluetooth device may be emitted by the bluetooth device; the sound of the encrypted Bluetooth address information of the Bluetooth device can also be recorded and sent out through other sound output devices. As mentioned above, the bluetooth terminal has a corresponding decryption algorithm, and after receiving the encrypted bluetooth address information transmitted in the form of voice, decrypts it to obtain the bluetooth address information. Therefore, the security and the selectivity of the Bluetooth connection are improved in the whole process of encrypting and decrypting the Bluetooth address.
And step S4, connecting the appointed Bluetooth device by using the decrypted Bluetooth address information. As described above, the bluetooth terminal obtains the decrypted bluetooth address information of the bluetooth device, and connects to the bluetooth device through the bluetooth address information. Wherein, the process of connecting the bluetooth device includes: directly connecting the Bluetooth device; or generating an instruction whether to connect the Bluetooth device, and connecting the Bluetooth device after receiving the instruction.
Further, after the step S4, connecting the specified bluetooth device by using the decrypted bluetooth address information, the method further includes: receive or transmit data to the bluetooth device. Thereby realizing data transmission between the Bluetooth terminal and the Bluetooth equipment.
Referring to fig. 2, in an embodiment, the step S3 of decrypting the sound information to obtain the bluetooth address information includes:
s31, judging whether the sound information contains coded audio data;
and S32, if the audio data contains the coded audio data, decoding the audio data according to the decryption algorithm corresponding to the specified encryption algorithm to obtain Bluetooth address information.
Step S31 is performed to determine whether the sound information contains encoded audio data. The encoded sound may contain the required information. Only if it is determined that the heard sound is indeed encoded is it necessary to proceed to the next step. The encoding method may be any method, for example, encoding using frequency, timbre, or the like.
And step S32, if the encoded audio data is contained, decoding the audio data according to the decryption algorithm corresponding to the specified encryption algorithm to obtain bluetooth address information. Since the bluetooth address information is encrypted in this embodiment, it is only determined that the decoded data is encrypted and encrypted by the encryption algorithm of the bluetooth device that the decoded data is encrypted that the sound information is the required sound information. The specific determination method may be any feasible method, for example, determining whether the decoded data conforms to a specific format. As described above, it can be confirmed whether the bluetooth address information is encrypted by a specified encryption algorithm. Accordingly, bluetooth address information is obtained.
Further, the step S31 of determining whether the sound information includes encoded audio data includes:
s311, judging whether the sound information has audio data of a plurality of different specific frequency combinations;
and S312, if yes, judging that the sound information contains the coded audio data.
The encoding method may be any method, and when encoding is performed using a frequency, encoding may be performed by assigning a sound segment having a specific frequency within a specific time period a seconds to a specific signal. For example, to encode information XYZ, where X corresponds to a specific frequency E, Y corresponds to a specific frequency R, and Z corresponds to a specific frequency T, the encoded sound should have a frequency ERT within three consecutive durations of a seconds.
Steps S311 to S312 are performed to determine whether the monitored sounds have a plurality of different specific frequencies. The specific frequency can be any feasible frequency, and can include infrasonic waves, sound waves, ultrasonic waves, low frequency bands, medium and high frequency bands, such as any frequency of 10-500KHz, 20-50KHz and 50-20 KHz. Frequencies that fit within certain frequency ranges may also be considered as specific frequencies, e.g. a frequency of 10-20Hz as specific frequency 1 and 200-2000Hz as specific frequency 2.
As described above, when encoding is performed using frequencies, it is determined whether or not a sound has a plurality of different specific frequencies, and if the sound has a plurality of different specific frequencies, it is determined that the sound has been encoded; if there is only a single specific frequency or no specific frequency, it is determined that the encoding is not performed.
In one embodiment, the step S4 of connecting the designated bluetooth device according to the decrypted bluetooth address information includes:
s401, comparing the sizes of specific numbers in the Bluetooth address information of a plurality of specified Bluetooth devices respectively;
s402, connecting the corresponding appointed Bluetooth equipment by using the decrypted Bluetooth address information with the maximum specific number.
As in steps S401-402 above, connection to the designated bluetooth device is achieved. In some scenarios, a plurality of bluetooth devices are connected alternatively, for example, a bluetooth speaker and a bluetooth headset are available for connection, and at this time, a connection object should be selected. Specific numbers (for example, positive integers) can be added to the bluetooth address information to determine which device should be connected, wherein the specific numbers can be added at the beginning of the bluetooth address, added at the end of the bluetooth address, or inserted in the bluetooth address. The specific mode comprises the following steps: compared with the specific digital size, the Bluetooth device with the specific digital size is a device to be connected. Wherein, the special number can be added during coding or encryption.
After the step S402 of connecting the corresponding specified bluetooth device by using the decrypted bluetooth address information with the largest specific number in one embodiment, the method includes:
s5, judging whether the connection time of the continuous connection with the appointed Bluetooth equipment exceeds the preset time;
and S6, if the preset time is exceeded, disconnecting the specified Bluetooth device.
Breaking the connection is achieved as in step S5-6 above. When the bluetooth connection time is too long, the required connection time may be exceeded (e.g., the owner has left, but forgotten to turn off the bluetooth), thus causing a large amount of power consumption. Accordingly, when the continuous connection is too long, i.e., exceeds a predetermined time, the connection is disconnected. Wherein the predetermined time may be 1 hour, 3 hours, 5 hours, 10 hours, etc.
