Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for displaying a bluetooth device list according to an embodiment of the present invention, where the method is applicable to a mobile terminal, such as a smart phone, a tablet computer, and other devices; referring to fig. 1, the method may include:
s101: maintaining a bluetooth searching state;
the display method of the Bluetooth equipment list in the embodiment of the invention is realized based on the Bluetooth technology, so that the Bluetooth search function of the mobile terminal needs to be started in the display process of the Bluetooth equipment list, so that the mobile terminal maintains the Bluetooth search state; optionally, the user may open the bluetooth search function by clicking a bluetooth shortcut operation on the mobile terminal, or may open the bluetooth search function by clicking a bluetooth icon on the mobile terminal, which is not limited in the embodiment of the present invention.
S102: receiving Bluetooth broadcast information;
s103: judging whether the Bluetooth broadcast information is sent by intelligent hardware of a target application;
it should be noted that the smart hardware developed based on the target application sends the bluetooth broadcast information to the surroundings, and the sent bluetooth broadcast information is encrypted by the first key of the target application, for example: the intelligent hardware can encrypt broadcast information through a first secret key of an appointed target application and then send a Bluetooth broadcast of 'i am a Bluetooth device and i ID XXXX' to the periphery;
it should be noted that, the target application in the embodiment of the present invention refers to an application that can be run on the mobile terminal, such as an instant messaging application that can be run on the mobile terminal;
in the embodiment of the invention, the intelligent hardware developed based on the target application is the intelligent hardware which reaches an agreement with the target application running on the mobile terminal; for example: the service provider of the instant messaging application can cooperate with an intelligent hardware manufacturer, and after the mobile terminal of the user loads the instant messaging application, the user can reach an agreement with the manufacturer server through the instant messaging application background to determine the intelligent hardware corresponding to the instant messaging application, so that the key of the target application is used as a Bluetooth key to realize the Bluetooth connection between the mobile terminal and the intelligent hardware;
the intelligent hardware of the target application can send the Bluetooth broadcast information to the periphery, and the sent Bluetooth broadcast information is encrypted through the first secret key of the target application, so that the mobile terminal can judge whether the Bluetooth broadcast information is sent by the intelligent hardware of the target application or not through the information characteristics in the Bluetooth broadcast information;
optionally, the mobile terminal may determine whether the identifier of the target application exists in the bluetooth broadcast information, if so, it may be determined that the bluetooth broadcast information is sent by the intelligent hardware of the target application, and if not, it may be determined that the bluetooth broadcast information is not sent by the intelligent hardware of the target application, and may be a bluetooth broadcast sent based on a standard bluetooth protocol;
optionally, a second key corresponding to the first key of the target application may be set in the mobile terminal, and broadcast information encrypted by the first key of the target application may be decrypted by the second key, based on which, after receiving the bluetooth broadcast information, the mobile terminal may decrypt the bluetooth broadcast information by the second key of the target application, and if decryption is successful, determine that the bluetooth broadcast information is sent by the smart hardware of the target application after being encrypted by the first key, and if decryption is failed, determine that the bluetooth broadcast information is not sent by the smart hardware of the target application, possibly based on the bluetooth broadcast sent by the standard bluetooth protocol;
obviously, the mobile terminal may also receive a bluetooth broadcast sent by a normal bluetooth device, where the bluetooth broadcast sent by the normal bluetooth device is defined based on a standard bluetooth protocol, and there is a difference from the bluetooth broadcast sent by the intelligent hardware encrypted by the first key of the target application in the embodiment of the present invention;
optionally, if the mobile terminal determines that the bluetooth broadcast information is not sent by the intelligent hardware of the target application, the mobile terminal may determine next received bluetooth broadcast information, and determine whether the next received bluetooth broadcast information is sent by the intelligent hardware of the target application.
S104: if the Bluetooth broadcast information is judged to be sent by the intelligent hardware of the target application, triggering and calling a second key of the target application corresponding to the first key and preset in a system file;
in the embodiment of the invention, the second key corresponding to the first key of the target application can be written into a system file in the mobile terminal in advance, so that the second key of the decrypted target application is preset in the mobile terminal system, the target application does not need to be opened in the mobile terminal, the key for decrypting the Bluetooth broadcast information is called, the operations that when the mobile terminal searches for intelligent hardware, a user opens the target application and clicks a Bluetooth searching button of an application interface to call the Bluetooth decryption key of the target application are reduced, and the simplification of the user operation is realized;
the second key is written in the system file of the mobile terminal and is taken over by the mobile terminal system, so that the mobile terminal can directly call the second key corresponding to the first key from the system file when judging that the received Bluetooth broadcast information is sent by the intelligent hardware of the target application;
optionally, in the embodiment of the present invention, a second key corresponding to the first key may be written in the bluetooth configuration file of the system in advance, and correspondingly, the mobile terminal may retrieve the second key corresponding to the first key, which is written in advance, from the bluetooth configuration file of the system.
Of course, the second key corresponding to the first key may also be embedded in the system files of other systems of the mobile terminal, as long as the logic sent by the intelligent hardware that determines that the bluetooth broadcast information is the target application is bound, and the triggering relationship with the logic for calling the second key preset in the system files;
obviously, the embodiment of the present invention may also bind the logic of receiving the bluetooth broadcast information and the triggering relationship of the logic of calling the second key preset in the system file, so that after receiving the bluetooth broadcast information, the mobile terminal directly decrypts the bluetooth broadcast information through the second key, and determines whether the bluetooth broadcast information is sent by the intelligent hardware of the target application according to the success or failure result of decryption; it is worth noting that after the bluetooth broadcast information is directly decrypted through the second secret key and is judged to be sent by the intelligent hardware of the target application, the description information of the intelligent hardware can be directly obtained and displayed in the bluetooth device list;
optionally, the system of the mobile terminal may be provided by a provider of the target application or a vendor who has a cooperation with the provider of the target application, and since the system of the mobile terminal and the target application achieve a predetermined protocol level, the system of the mobile terminal may implement the preset of the second key of the target application; optionally, in the embodiment of the present invention, in a system development stage, the preset completion of the second password of the target application in the system may be realized.
The first key and the second key are two keys corresponding to the target application, one first key corresponds to one second key, and the two keys can be used for encrypting and decrypting each other. The first secret key is a private key of the target application, and the second secret key is a public key of the target application; or, the first secret key is a public key of the target application, and the second secret key is a private key of the target application. In a key pair, the public key is public and does not need to be kept secret, while the private key is held by the individual himself and must be kept in good care and care for the confidentiality. If data is encrypted with one of the keys, only the corresponding key can be decrypted. If decryption of data is possible with one of the keys, the data must be encrypted with the corresponding key.
S105: decrypting the Bluetooth broadcast information according to the second key to obtain the description information of the intelligent hardware;
and description information of the intelligent hardware such as the name of the intelligent hardware and the like.
S106: and when a Bluetooth device list display instruction is detected, displaying the Bluetooth device list with the description information.
It should be noted that the instruction for detecting the list of bluetooth devices disclosed in the embodiment of the present invention includes: if an instruction for entering a Bluetooth setting page from a system setting interface is detected, determining that a Bluetooth equipment list display instruction is detected; or if the trigger operation of the shortcut operation displayed on the bluetooth device list is detected, determining that a bluetooth device list display instruction is detected, or if the trigger operation of the bluetooth device list icon is detected, determining that the bluetooth device list display instruction is detected;
optionally, in order to be different from the display of the bluetooth device searched based on the standard bluetooth protocol in the system bluetooth setting page, when the description information of the intelligent hardware of the target application is displayed in the system bluetooth device list, the embodiment of the present invention may display a first list and a second list in the system bluetooth setting page, where the first list shows the description information of the hardware device of the target application, and the second list shows the information of the bluetooth device searched based on the standard bluetooth protocol.
In the method for displaying the bluetooth device list provided by the embodiment of the invention, since the second key corresponding to the first key of the target application is preset in the system file, after the mobile terminal receives the bluetooth broadcast information sent by the intelligent hardware, the mobile terminal can directly call the second key preset in the system file on the internal layer of the system, so that the bluetooth broadcast information is decrypted to obtain the description information of the intelligent hardware, and the bluetooth device list with the description information is displayed when a bluetooth device list display instruction is detected; it can be seen that, in the embodiment of the present invention, a user does not need to open a target application any more, and manually triggers a bluetooth scan button of an application interface to form search of a bluetooth device and display of a bluetooth device list, but can decrypt bluetooth broadcast information at an internal level of a system to complete scanning of a hardware device of the target application, thereby realizing display of description information of the hardware device of the target application in the bluetooth device list; meanwhile, the embodiment of the invention can enable the intelligent hardware to be rapidly discovered by the mobile terminal, thereby effectively improving the connection rate of the intelligent hardware.
Optionally, because the bluetooth technology belongs to a short-distance wireless connection technology, after a user opens a bluetooth device on a mobile terminal, in a process of generating a bluetooth list, the bluetooth device needs to be maintained in a bluetooth search state, but a bluetooth coverage area changes with the movement of the mobile terminal, and the intelligent hardware searched at the last time cannot be connected currently with the change of the bluetooth coverage area, so that in a process of displaying the bluetooth device list with the description information, a distance between the intelligent hardware decrypted to the description information and the mobile terminal can be calculated, the intelligent hardware decrypted to the description information and having a distance conforming to a preset connection distance is displayed in the bluetooth device list, and the preset connection distance refers to a distance within the bluetooth coverage area;
optionally, in the embodiment of the present invention, the distance between the intelligent hardware and the mobile terminal may be calculated through a bluetooth technology, if the intelligent hardware decrypted to the description information at the previous time detects a bluetooth device list display instruction, and the distance between the intelligent hardware decrypted to the description information and the mobile terminal (the distance exceeding the bluetooth coverage range) cannot be calculated, it may be determined that the distance between the intelligent hardware decrypted to the description information and the mobile terminal exceeds a preset connection distance, and if the intelligent hardware decrypted to the description information at the previous time detects a bluetooth device list display instruction, it may also be determined that the distance between the intelligent hardware decrypted to the description information and the mobile terminal does not exceed the preset connection distance.
