After the terminal device finds the BLE device, it can perform a pairing operation, and after exchanging pairing information, the first connection is established. After the connection is successful, the terminal device can control the BLE device to unlock. However, when the terminal device needs to unlock the BLE device again, it needs to reselect the BLE device in the Bluetooth list of the terminal device to connect before controlling the BLE device to unlock, resulting in low unlocking efficiency.

[0089] In response to the above problems, in an embodiment of the present application, when a terminal device needs to unlock a BLE device, it can receive at least one broadcast message broadcast by at least one BLE device, and determine the target BLE device in the BLE device list stored in the terminal device according to the at least one broadcast message, wherein the target BLE device has read encryption or write authentication permissions, and unlock the target BLE device according to the device address of the target BLE device. Through the above method, after the first pairing is successful, the target BLE device with read encryption or write authentication permissions can be saved to the BLE device list, so that when the terminal device needs to unlock the BLE device, it only needs to control the unlocking of the BLE device according to the broadcast message broadcast by the BLE device and the BLE device list, thereby improving the unlocking efficiency.

[0096] The broadcast message broadcasted by the BLE device can be received in the following ways: the terminal device can enter the scanning mode, and the scanning mode can receive the broadcast message broadcasted by the BLE device; after the terminal device receives the broadcast message, it can obtain the encrypted device address of the BLE device in the broadcast message.

[0101] The key may refer to a symmetric key, and the key may be used to encrypt a plaintext device address or may be used to decrypt a plaintext device address.

[0102] The plaintext device address may refer to a unique identifier of a BLE device. For example, the plaintext device address may refer to a Media Access Control Address (MAC address) of a BLE device. According to the plaintext device address, a unique corresponding BLE device may be determined. For example, the plaintext device address may be "C8:3A:3F:2D:1B:09".

[0103] For example, the BLE device list may be as shown in Table 1. See Table 1.

[0113] The preset threshold may be a value set in advance by the user in the BLE device.

[0114] In an embodiment of the present application, when a terminal device needs to unlock a BLE device, it can first receive at least one broadcast message broadcast by at least one BLE device, and obtain a BLE device list stored in the terminal device, wherein the BLE device list may include at least one key and a plaintext device address corresponding to each key; according to at least one broadcast message and the BLE device list, a target BLE device is determined in at least one BLE device, and the HID feature permission of the target BLE device is a read encryption permission or a write authentication permission, and the HID feature permission is used to make the terminal device and the target BLE device successfully paired for the first time, and the key and plaintext device address of the target BLE device are stored in the BLE device list; according to the device address of the target BLE device, the target BLE device is controlled to be unlocked.

[0118] It should be noted that the execution process of the above S401 can refer to S201 and will not be described in detail here.

[0119] S402: Determine at least one to-be-selected BLE device and an encrypted device address of each to-be-selected BLE device according to at least one broadcast message.

[0120] The broadcast message includes the encrypted device address of the BLE device.

[0121] The BLE device to be selected and the encrypted device address of the BLE device to be selected can be determined in the following manner: for any broadcast message, the BLE device corresponding to the broadcast message is determined as the BLE device to be selected; the encrypted device address of the BLE device included in the broadcast message is determined as the encrypted device address of the BLE device to be selected.

[0122] S403: For any encrypted device address, decrypt the encrypted device address using a key.

[0133] S408. Send a connection request to the target BLE device according to the device address of the target BLE device, and receive a connection success response message sent by the target BLE device.

[0134] The terminal device obtains the target encryption device address of the target BLE device and generates a connection request to be encrypted; uses the key to encrypt the connection request to be encrypted to obtain an encrypted connection request; sends the encrypted connection request to the target BLE device according to the target encryption device address; after receiving the encrypted connection request, the target BLE device uses the key to decrypt the encrypted connection request. If the decryption is successful, a connection success response message is sent to the terminal device; if the decryption fails, no operation is performed.

[0135] S409: Send an unlock request to the target BLE device according to the connection success response message, so that the target BLE device is unlocked when it detects that the Bluetooth signal strength of the terminal device is greater than or equal to a preset threshold.

[0136] After receiving the unlock request, the target BLE device detects the Bluetooth signal strength with the terminal device at a preset frequency. If the Bluetooth signal strength is greater than or equal to the preset threshold, the unlock operation is performed. The preset frequency can be a frequency set by the user in the target BLE device in advance, for example, once per second.

[0137] In an embodiment of the present application, when the terminal device needs to unlock the target BLE device, at least one to-be-selected BLE device and the encrypted device address of each to-be-selected BLE device can be determined based on at least one received broadcast message; for any encrypted device address, the encrypted device address is decrypted using the key stored in the BLE device list, and it is determined whether the verification result of the data to be verified obtained by the decryption process is a successful verification; if so, the decryption result corresponding to the encrypted device address is determined to be a successful decryption; if not, the decryption result corresponding to the encrypted device address is determined to be a failed decryption; based on the decryption result, the target encrypted device address and the corresponding target BLE device are determined; based on the device address of the target BLE device, a connection request is sent to the target BLE device, and a successful connection response message is received from the target BLE device; based on the successful connection response message, an unlock request is sent to the target BLE device, so that the target BLE device is unlocked when it detects that the Bluetooth signal strength of the terminal device is greater than or equal to a preset threshold. Through the above method, the terminal device can decrypt the encrypted device address. When the decryption result is successful, it can be determined that the terminal device and the target BLE device have been successfully paired for the first time. Therefore, when the Bluetooth signal strength between the target BLE device and the terminal device is greater than or equal to the preset threshold, the target BLE device is automatically unlocked, thereby improving the unlocking efficiency.

[0138] Based on any of the above embodiments, Figure 5 , describes in detail the process of first pairing between the terminal device and the target BLE device.

[0145] According to the HID service information sent by the target BLE device, the first identification code and the second identification code are searched in the HID service information, wherein the first identification code is used to indicate the read encryption permission and the second identification code is used to indicate the write authentication permission; if the first identification code and / or the second identification code exists in the HID service information and the value corresponding to the first identification code and / or the second identification code is 1, it can be determined that the target BLE device has the HID feature permission, and the HID feature permission is the read encryption permission or the write authentication permission.

[0146] If the target BLE device has HID feature permissions, a pairing request is sent to the target BLE device to pair the terminal device with the target BLE device.

[0147] The pairing process can be performed in the following manner: the target BLE device receives the pairing request, generates a first pairing code, and displays the first pairing code on the display module of the target BLE device; the user inputs the second pairing code into the terminal device according to the first pairing code displayed on the display module; the terminal device receives the second pairing code, and randomly generates a first random number, uses a preset algorithm for the second pairing code and the first random number, and generates a first confirmation value; the BLE device randomly generates a second random number, uses a preset algorithm for the first pairing code and the second random number, generates a second confirmation value, and sends the second confirmation value to the terminal device; after receiving the second confirmation value, the terminal device compares whether the first confirmation value and the second confirmation value are the same, if they are the same, the pairing result is a successful pairing, if they are different, the pairing result is a failed pairing. Among them, the preset algorithm can refer to an elliptic curve algorithm, etc.

[0148] S504: After the pairing result is successful, obtain the key and plaintext device address of the target BLE device.

[0149] After successful pairing, the terminal device sends a pairing success message to the target BLE device; after receiving the pairing success message, the target BLE device sends the second random number and the plaintext device address of the target BLE device to the terminal device; the terminal device receives the second random number and the plaintext device address, and uses a preset algorithm for the second random number and the second pairing code to generate a key.

[0150] S505. The key and the plaintext device address are stored correspondingly in the BLE device list.

[0151] The key and plaintext device address corresponding to the target BLE device are stored in the BLE device list. The BLE device list is located in the storage space of the terminal device.

[0152] In an embodiment of the present application, before the terminal device needs to unlock the target BLE device, the terminal device also needs to pair with the target BLE device for the first time. After the terminal device establishes a Bluetooth connection with the target BLE device for the first time, the HID service information of the target BLE device is obtained, and according to the HID service information, it is determined whether the target BLE device has read encryption permission or write authentication permission. If so, the terminal device and the target BLE device are paired to obtain the first pairing result; after the pairing result is a successful pairing, the key and plaintext device address of the target BLE device are obtained, and the key and plaintext device address are stored correspondingly in the BLE device list. Through the above method, the key and plaintext device address of the target BLE device with read encryption or write authentication HID feature permission and the pairing result is a successful pairing are stored in the BLE device list at the time of the first connection, so that when the terminal device needs to unlock the target BLE device again, the target BLE device can be automatically unlocked without feeling, thereby improving the efficiency of unlocking.

[0153] Based on any of the above embodiments, Figure 6 , describes in detail the interaction process of the first pairing between the terminal device and the target BLE device.
