[0002] Bluetooth devices apply Bluetooth technology and are free from the bondage of wires, so they are favored by more and more users.

[0003] Some Bluetooth devices are provided with buttons. The user makes the Bluetooth device enter the pairing mode by long-pressing the button. After the second terminal searches for the Bluetooth device, it displays the device information of the searched Bluetooth device. After receiving the confirmation information of the device information from the user, it pairs with the Bluetooth device having the device information. After the pairing is successful, a Bluetooth connection is established between the second terminal and the Bluetooth device.

[0161] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0163] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0164] Figure 1 is a flowchart of a method for pairing a Bluetooth device shown according to an exemplary embodiment. Figure 1 The method shown is applied to a first terminal, and the first terminal may be a mobile phone, a tablet, a notebook, a wearable device, etc. Figure 1 The method shown includes:

[0165] In step 101, after logging in to the server using an account, connection information corresponding to the account in the server is obtained. The connection information includes the MAC address and the key of the Bluetooth device.

[0166] The first terminal logs in to the server using an account. After the first terminal successfully pairs with the Bluetooth device and establishes a Bluetooth connection, it will obtain the account, the MAC address (Media Access Control Address) of the Bluetooth device, and the key. The key is used to encrypt and decrypt communication data when the first terminal using the account and the Bluetooth device communicate via Bluetooth.

[0167] The first terminal uploads the combined information of the account, the MAC address of the Bluetooth device, and the key to the server, so that when the account is used again, the first terminal using the account can obtain the MAC address and the key of the Bluetooth device corresponding to the account from the server.

[0168] The Bluetooth device supports traditional Bluetooth technology and low-power Bluetooth technology. The Bluetooth device may be a Bluetooth headset, etc.

[0169] In step 102, broadcast data sent by Bluetooth devices located around the first terminal is obtained.

[0170] Bluetooth Low Energy (BLE) features low power consumption. Before a Bluetooth device establishes a Bluetooth connection with a first terminal, it can send broadcast data via Bluetooth Low Energy, and the broadcast data can include a small amount of data information.

[0171] In step 103, in response to the broadcast data including the key obtained from the server, pair the first terminal and the Bluetooth device according to the MAC address of the Bluetooth device and the key.

[0172] For a Bluetooth device that has established a Bluetooth connection with the first terminal using an account in the past, the key (i.e., the key obtained from the server) is stored in the Bluetooth device. After such a Bluetooth device is powered on, it can send broadcast data via Bluetooth Low Energy, and the broadcast data includes the key. The keys stored in the Bluetooth device can be presented in a list form.

[0173] After the first terminal obtains the broadcast data sent by the surrounding Bluetooth devices, determine whether the broadcast data includes the key. After determining that the broadcast data includes the key obtained from the server, determine whether to pair the first terminal and the Bluetooth device according to the MAC address of the Bluetooth device and the key obtained from the server. If so, pair the first terminal and the Bluetooth device; if not, do not pair the first terminal and the Bluetooth device.

[0174] In some embodiments, the first terminal pairs the first terminal and the Bluetooth device according to the MAC address of the Bluetooth device and the key, which can be achieved in the following way:

[0175] Step a1: Receive the encrypted actual MAC address of the Bluetooth device sent by the Bluetooth device.

[0176] Step a2: Use the key to decrypt the encrypted actual MAC address to obtain the actual MAC address.

[0177] Step a3: Determine whether the actual MAC address obtained in step a2 is consistent with the MAC address obtained from the server. If it is consistent, start pairing the first terminal and the Bluetooth device; if it is not consistent, do not pair the first terminal and the Bluetooth device.

[0178] In some embodiments, based on steps a1 - a3, when the first terminal pairs the first terminal and the Bluetooth device according to the MAC address of the Bluetooth device and the key, it may further include:

[0179] Step a4: Obtain the Bluetooth Low Energy address of the Bluetooth device.

[0180] The Bluetooth device can broadcast the Bluetooth Low Energy address via Bluetooth Low Energy, and the first terminal can obtain the Bluetooth Low Energy address of the Bluetooth device via Bluetooth Low Energy.

[0181] Step a5: Encrypt the Bluetooth Low Energy address using a key.

[0182] Step a6: Send the encrypted Bluetooth Low Energy address to the Bluetooth device.

[0183] The Bluetooth device decrypts the encrypted Bluetooth Low Energy address using an internal key. After determining that the decrypted Bluetooth Low Energy address is the same as the actual Bluetooth Low Energy address of the Bluetooth device, it encrypts the actual MAC address of the Bluetooth device using the key and sends the encrypted actual MAC address to the first terminal.

[0184] In some embodiments, the operation of pairing the first terminal and the Bluetooth device can be implemented in the following manner:

[0185] Step b1: Send a Bluetooth pairing request to the Bluetooth device according to the MAC address of the Bluetooth device. The Bluetooth pairing request triggers the first terminal to generate verification code 1 and the Bluetooth device to generate verification code 2.

[0186] Step b2: Receive the second notification sent by the Bluetooth device. The second notification is sent by the Bluetooth device after determining that the second terminal has passed the verification according to verification code 2.

[0187] Step b3: Verify the Bluetooth device according to verification code 1. In response to the Bluetooth device passing the verification, it is determined that the first terminal and the Bluetooth device are successfully paired.

[0188] The second terminal generates password 1 according to the terminal private key of the second terminal and the public key of the Bluetooth device, encrypts verification code 1 using password 1, and sends the encrypted verification code 1 to the Bluetooth device.

[0189] The Bluetooth device locally stores a key list, which includes at least one key data. When performing this step, the second terminal does not send the terminal public key of the second terminal to the Bluetooth device. Therefore, the Bluetooth device decrypts the encrypted verification code 1 according to the key in the key list. If the decryption is successful, verification code 1 is obtained, and it is determined whether verification code 1 and verification code 2 are the same. If they are the same, it is determined that the second terminal has passed the verification.

[0190] The Bluetooth device generates password 2 according to the private key of the Bluetooth device and the public key of the second terminal, encrypts verification code 2 using password 2, and sends the encrypted verification code 2 to the second terminal. The second terminal decrypts the encrypted verification code 2 using password 1 to obtain verification code 2, and determines whether verification code 2 and verification code 1 are the same. If they are the same, it is determined that the Bluetooth device has passed the verification.

[0191] In some embodiments, in response to the broadcast data including the key, an acknowledgment notification of the Bluetooth device is output, and after receiving the acknowledgment information of the Bluetooth device, an operation of sending a request to the Bluetooth device according to the MAC address and the key of the Bluetooth device is started.

[0192] For example, in response to the broadcast data including the key, a window pops up, and the window displays "These are the headphones you have connected to on other devices". The window displays an OK option and a Cancel option. If the user's selection operation on the OK option is received, then an operation of pairing the first terminal and the Bluetooth device according to the MAC address and the key of the Bluetooth device is started.

[0193] In this embodiment, a user confirmation step is added, and the user can choose whether to allow the second terminal to establish a Bluetooth connection with the Bluetooth device selected by the second terminal according to their own will, improving the user experience.

[0194] In the embodiments of the present disclosure, after logging in to the server using an account, connection information corresponding to the account in the server is obtained. The information includes the MAC address and the key of the Bluetooth device. Broadcast data sent by the Bluetooth device located around the second terminal via low-power Bluetooth is obtained. In response to the broadcast data including the key obtained from the server, the first terminal and the Bluetooth device are paired according to the MAC address and the key of the Bluetooth device. By adopting the above method, it is possible to control the Bluetooth device to enter the pairable mode, eliminating the operation of the user long-pressing the button on the Bluetooth device to make the Bluetooth device enter the pairable mode, and improving the user experience.

[0195] Figure 2 It is a flowchart of another Bluetooth device pairing method shown according to an exemplary embodiment. Figure 2 The method shown is applied to the second terminal, and the second terminal can be a mobile phone, a tablet, a laptop, a wearable device, etc. Figure 2 The method shown includes:

[0196] In step 201, after logging in to the server using an account, the second terminal and the Bluetooth device are paired.

[0197] In some embodiments, the operation of pairing the second terminal and the Bluetooth device can be implemented in the following manner:

[0198] The first step, after logging in to the server using the account, a first notification sent by the Bluetooth device is received. The first notification is a notification sent by the Bluetooth device after determining that the second terminal has passed the verification according to the second terminal public key generated by the second terminal and the Bluetooth device private key of the Bluetooth device. The first notification includes the MAC address of the Bluetooth device, and the Bluetooth device is verified according to the second terminal private key of the second terminal and the Bluetooth device public key of the Bluetooth device.

[0199] In the second step, in response to successful verification of the Bluetooth device, a Bluetooth pairing request is sent to the Bluetooth device according to the MAC address of the Bluetooth device. The Bluetooth pairing request triggers the second terminal (which can be the second terminal protocol stack) to generate a first verification code, and the Bluetooth device (which can be the Bluetooth device protocol stack) to generate a second verification code.

[0200] In the third step, receive the second notification sent by the Bluetooth device. The second notification is a notification sent by the Bluetooth device after determining that the second terminal has passed the verification according to the second verification code.

[0201] In the fourth step, verify the Bluetooth device according to the first verification code. In response to the Bluetooth device passing the verification, it is determined that the second terminal and the Bluetooth device are successfully paired.

[0202] In response to the Bluetooth device failing to pass the verification, it is determined that the pairing between the second terminal and the Bluetooth device fails.

[0203] In this embodiment, the second terminal and the Bluetooth device can send data via low energy Bluetooth.

[0204] In this embodiment, the second terminal and the Bluetooth device perform pairing by using the terminal public key of the second terminal, the terminal private key of the second terminal, the Bluetooth device public key, the Bluetooth device private key, the first verification code, and the second verification code.

[0205] The Bluetooth device public key and the Bluetooth device private key can be fixed, and the second terminal public key and the second terminal private key can be temporarily generated by the second terminal.

[0206] In step 202, in response to successful pairing, a key is generated.

[0207] The generated key can be referred to as the Account Key.

[0208] For example, the second terminal generates a new terminal public key and a terminal private key, calculates the new terminal public key and the terminal private key, and determines the calculation result as the key Account Key. Another example is that the second terminal randomly generates the key Account Key. This embodiment does not limit the method of generating the key Account Key.

[0209] In step 203, send the key to the Bluetooth device.

[0210] In step 204, send the combined information of the account, the MAC address of the Bluetooth device, and the key to the server.

[0211] In some embodiments, after receiving the first notification, the second terminal sends a first switching instruction to the Bluetooth device. The first switching instruction is used to instruct the Bluetooth device to perform an input / output capability switch, so that the Bluetooth device has the permission to obtain the second verification code and send the second notification;

[0212] After determining successful pairing with the Bluetooth device, the second terminal sends a second switching instruction to the Bluetooth device, and the second switching instruction is used to instruct the Bluetooth device to switch back to the originally used input / output capabilities.

[0213] For example, the originally used input / output capabilities (IO Capabilities) of the Bluetooth device is NoInput / NoOutput. After receiving the first notification, the second terminal sends a first switching instruction to the Bluetooth device via Bluetooth Low Energy, causing the Bluetooth device to switch the IO Capabilities to Display / YesNo. After determining successful pairing with the Bluetooth device, the second terminal sends a second switching instruction to the Bluetooth device, causing the Bluetooth device to switch the IO Capabilities back to the originally used NoInput / NoOutput.

[0214] After receiving the first notification, the second terminal can send a first switching instruction to the Bluetooth device via Bluetooth Low Energy,

[0215] In some embodiments, the second terminal can also perform the following operations:

[0216] Step c1: Obtain the public key of the Bluetooth device.

[0217] For example, the server stores the correspondence between the device information of the Bluetooth device, the public key of the Bluetooth device, and the private key of the Bluetooth device.

[0218] The second terminal receives the device information of the Bluetooth device sent by the Bluetooth device and obtains the public key of the Bluetooth device corresponding to the device information in the server.

[0219] The second terminal receives the device information of the Bluetooth device sent by the Bluetooth device via Bluetooth Low Energy.

[0220] The device information of the Bluetooth device can be the identifier of the Bluetooth device, such as the device model, unique code, etc. of the Bluetooth device.

[0221] After turning on the Bluetooth, the second terminal can scan for the Bluetooth Low Energy service, obtain the device model broadcast by the Bluetooth device via Bluetooth Low Energy. After determining that the Bluetooth device is a specified device according to the device model of the Bluetooth device, such as determining that the Bluetooth device is a device produced by a specified manufacturer, a corresponding notification is popped up. After receiving the confirmation information from the user, a temporary terminal private key and a terminal public key are generated, the public key of the Bluetooth device is obtained from the server, the Bluetooth device is verified according to the terminal private key and the public key of the Bluetooth device, and the terminal public key is sent to the Bluetooth device, so that the Bluetooth device verifies the second terminal according to the private key of the Bluetooth device and the terminal public key.

[0222] Step c2: Generate a first key based on the terminal private key of the second terminal and the public key of the Bluetooth device.

[0223] A preset algorithm can be used to calculate the terminal private key and the public key of the Bluetooth device, and the calculation result can be determined as the first key. The first key can be referred to as AES Key1.

[0224] Step c3: Encrypt the pairing request data using the first key.

[0225] Step c4: Send the encrypted pairing request data and the terminal public key of the second terminal to the Bluetooth device.

[0226] The Bluetooth device generates a second key based on the terminal public key and the Bluetooth device private key, decrypts the encrypted pairing request data using the second key, and in response to successful decryption of the encrypted pairing request data, encrypts the pairing request response data using the second key to generate a first notification including the encrypted pairing request response data. The encrypted pairing request response data includes the MAC address of the Bluetooth device, and sends the first notification to the second terminal. The second key can be referred to as AES Key2.

[0227] In this embodiment, the second terminal and the Bluetooth device can send data via low - power Bluetooth.

[0228] Next, an example of the data formats of the pairing request and the terminal public key of the second terminal is given. Table 1.1 shows the data formats of the pairing request and the terminal public key, and Table 1.2 shows the specific data format of the pairing request.

[0229] Table 1.1

[0230] Byte Length (bits) Description Is Mandatory 0-15 128 Pairing Request Mandatory 16-79 512 Public key Optional

[0231] Table 1.2

[0232]

[0233]

[0234] In Tables 1.1 and 1.2, Seeker refers to the second terminal, such as a mobile phone, and Provider refers to the Bluetooth device, such as a Bluetooth headset.

[0235] Based on the settings in steps c1 - c4, for the verification of the Bluetooth device according to the terminal private key of the second terminal and the Bluetooth device public key in the above - mentioned first step, it can be achieved in the following way: First, use the first key to decrypt the encrypted pairing request response data in the first notification; Second, in response to the successful decryption of the encrypted pairing request response data, it is determined that the Bluetooth device passes the verification. On the contrary, in response to the failure of decrypting the encrypted pairing request response data, it is determined that the Bluetooth device fails the verification.

[0236] In this embodiment, the second terminal determines the first key. Based on this, the sending of the key to the Bluetooth device in step 203 can be achieved in the following way: Encrypt the key using the first key and send the encrypted key to the Bluetooth device. The Bluetooth device uses the internal second key to decrypt the encrypted key to obtain the key and stores the key.

[0237] A list, Account key list, can be set in the Bluetooth device. The list can store a certain number of keys, Account key. For example, the list can store two keys, Account key. If the list is full, the earliest - stored key, Account key, can be deleted so as to store the new key, Account key, in the list.

[0238] The following gives an example of the data format of the pairing request response. Table 1.3 shows the data format of the pairing request response, and Table 1.4 shows the specific data format of the pairing request response.

[0239] Table 1.3

[0240] Byte Length (bits) Description Remarks 0-15 128 Pairing Response Pairing Response data is sent to the second terminal

[0241] Table 1.4

[0242] Byte Length (bits) Value Remarks 0 8 0x01 = Key-based Pairing Response 1-6 48 BR / EDR address of the Provider 7-15 72 Random number

[0243] In Table 1.4, Provider refers to the Bluetooth device, such as a Bluetooth headset. The BR / EDR address of Provider refers to the traditional Bluetooth address of the Bluetooth device, that is, the MAC address.

[0244] In some embodiments, the second terminal can also perform the following operations:

[0245] d1. Encrypt the first verification code using the first key.

[0246] d2. Send the encrypted first verification code to the Bluetooth device.

[0247] Cause the Bluetooth device to decrypt the encrypted first verification code using the second key, determine whether the decryption result of the encrypted first verification code is consistent with the second verification code. If they are consistent, encrypt the second verification code using the second key to obtain the encrypted second verification code, and send a second notification including the encrypted second verification code to the second terminal.

[0248] The first verification code can be referred to as Passkey1, and the second verification code can be referred to as Passkey2.

[0249] Based on the settings in steps d1 and d2, the operation of verifying the Bluetooth device according to the first verification code in the above fourth step can be implemented in the following manner: First, decrypt the encrypted second verification code in the second notification using the first key; Second, determine whether the decryption result of the encrypted second verification code is consistent with the first verification code; Third, if they are consistent, determine that the Bluetooth device passes the verification, and if they are not consistent, determine that the Bluetooth device fails the verification.

[0250] The following gives an example of the data format of the encrypted verification code. Table 1.5 shows the data format of the encrypted verification code, and Table 1.6 shows the specific data format of the encrypted verification code.

[0251] Table 1.5

[0252] Byte Length (bits) Description 0-15 128 Encrypted Passkey

[0253] Table 1.6

[0254]

[0255] In Table 1.6, Seeker's Passkey refers to the second verification code used by the second terminal, and Provider's Passkey refers to the first verification code used by the Bluetooth device.

[0256] In some embodiments, after the second terminal sends the combined information to the server, it can send an instruction for deleting the combined information to the server under the condition of meeting the condition for deleting the combined information, so that the server deletes the combined information stored internally according to this instruction.

[0257] For example, after the second terminal receives an instruction triggered by the user for deleting the combined information, it sends an instruction for deleting the combined information to the server. Another example is that there is a preset duration. After the second terminal determines that the duration for which the server stores the combined information reaches the preset duration, it automatically sends an instruction for deleting the combined information to the server.

[0258] After the server deletes the combined information, the relevant content displayed on the UI menu of the second terminal is deleted.

[0259] It should be noted that the second terminal executing Figure 2 the method shown and the first terminal executing Figure 1 the method shown can be the same terminal or different terminals.

[0260] In the embodiments of the present disclosure, after the second terminal logs in to the server using an account, it pairs the second terminal with a Bluetooth device. In response to successful pairing, a key is generated and sent to the Bluetooth device, enabling the Bluetooth device to broadcast the key. The combined information of the account, the MAC address of the Bluetooth device, and the key is sent to the server, enabling the terminal using the account to obtain the MAC address and key of the Bluetooth device corresponding to the account from the server and execute Figure 1 the method shown.

[0261] During the pairing process between the Bluetooth device and the second terminal, the second terminal is verified once based on the Bluetooth device private key and the terminal public key, and verified twice based on the second verification code generated by the Bluetooth device. After both verifications pass, the verification of the second terminal is completed.

[0262] Figure 3 FIG. is a flowchart of a Bluetooth device pairing method shown according to an exemplary embodiment. Figure 3 The method shown is applied to a Bluetooth device, which can be a device such as a Bluetooth headset. Figure 3 The method shown may include:

[0263] In step 301, after receiving the terminal public key sent by the second terminal, the second terminal is verified based on the Bluetooth device private key of the Bluetooth device and the terminal public key.

[0264] The terminal public key sent by the second terminal can be received via low energy Bluetooth.

[0265] In some embodiments, the second terminal generates a first key based on the terminal private key and the Bluetooth device public key, encrypts the pairing request data using the first key to obtain the encrypted pairing request data, and sends the encrypted pairing request data to the Bluetooth device. The Bluetooth device can receive the terminal public key and the encrypted pairing request data sent by the second terminal via low energy Bluetooth.

[0266] In this case, the verification of the second terminal based on the Bluetooth device private key of the Bluetooth device and the terminal public key can be achieved in the following manner: First, a second key is generated based on the Bluetooth device private key and the terminal public key; second, the encrypted pairing request data is decrypted using the second key; third, in response to successful decryption of the encrypted pairing request data, it is determined that the second terminal passes the verification, and conversely, in response to failed decryption of the encrypted pairing request data, it is determined that the second terminal fails the verification.

[0267] A preset algorithm can be used to calculate the private key of the Bluetooth device and the public key of the terminal, and the calculation result is determined as the second key.

[0268] In step 302, in response to the successful verification of the second terminal, a first notification is sent to the second terminal, and the first notification includes the MAC address of the Bluetooth device.

[0269] After the second terminal device determines that the Bluetooth device is successfully verified according to the private key of the second terminal and the public key of the Bluetooth device, a Bluetooth pairing request is sent to the Bluetooth device according to the MAC address of the Bluetooth device included in the first notification. The Bluetooth pairing request triggers the second terminal (which can be the second terminal protocol stack) to generate a first verification code, and the Bluetooth device (which can be the Bluetooth device protocol stack) to generate a second verification code.

[0270] The first notification can be sent to the second terminal via low - power Bluetooth.

[0271] In step 303, the second terminal is verified according to the second verification code.

[0272] In some embodiments, after obtaining the first verification code generated by the second terminal, the second terminal can encrypt the first verification code using the first key to obtain the encrypted first verification code, and send the encrypted first verification code to the Bluetooth device. The Bluetooth device can receive the encrypted first verification code sent by the second terminal.

[0273] In this case, the Bluetooth device verifies the second terminal according to the second verification code, which can be achieved in the following way: First, decrypt the encrypted first verification code using the second key; Second, determine whether the decryption result is consistent with the second verification code; Third, if they are consistent, it is determined that the second terminal passes the verification, and conversely, if they are inconsistent, it is determined that the second terminal fails the verification.

[0274] In step 304, in response to the successful verification of the second terminal, a second notification is sent to the second terminal. The second notification is used to trigger the second terminal to verify the Bluetooth device according to the first verification code. In response to the successful verification of the Bluetooth device, it is determined that the second terminal and the Bluetooth device are successfully paired.

[0275] The second notification can be sent to the second terminal via low - power Bluetooth.

[0276] In some embodiments, the second terminal can encrypt the second verification code using the second key to generate a second notification including the encrypted second verification code, and send the second notification including the encrypted second verification code to the second terminal.

[0277] The second terminal decrypts the encrypted second verification code using the first key to obtain the second verification code, determines whether the second verification code is consistent with the first verification code. If they are consistent, it determines that the Bluetooth device verification is passed and determines that the second terminal is successfully paired with the Bluetooth device.

[0278] In some embodiments, after the second terminal determines that it is successfully paired with the Bluetooth device, it obtains a key, for example, generates a new key, encrypts the key using the first key to obtain the encrypted key, and sends the encrypted key to the Bluetooth device.

[0279] After receiving the encrypted key sent by the second terminal, the Bluetooth device decrypts the encrypted key using the second key to obtain the key and stores the key. During subsequent startup processes, the Bluetooth device can broadcast the stored key via Bluetooth Low Energy. The Bluetooth device can store the key in a key list.

[0280] In the embodiments of the present disclosure, during the pairing process between the Bluetooth device and the second terminal, the second terminal is verified once based on the Bluetooth device private key and the terminal public key, and is verified twice based on the second verification code generated by the Bluetooth device. After both verifications are passed, the verification of the second terminal is completed.
