Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
The terms "a," "an," "the," and "said" are used in this specification to denote the presence of one or more elements/components/etc.; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components/etc. in addition to the listed elements/components/etc.; the terms "first" and "second" and the like are used merely as labels, and are not intended to limit the number of their objects.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.
In the bluetooth communication process, it is generally divided into: the data transmitting end (also called peripheral end, broadcasting end) and the data receiving end (also called central end, scanning end). Wherein, the data transmitting end mainly performs data broadcasting (transmitting); the central end mainly scans (receives) data. For example, if bluetooth is used to achieve close-coupled tracking, the handset will start broadcasting and scanning at the same time, i.e. the peripheral end and the central end.
In the prior art, since a device in which an operating system of a first type is installed is used as a data transmitting end, and when a related application performs bluetooth broadcasting in a background mode, data broadcast by the application cannot be scanned and read by any data receiving end (including devices of the same type of operating system as the data transmitting end and devices of a different type of operating system as the data transmitting end). An Operating System (OS) is a computer program that manages hardware and software resources in a related device. In the equipment with different types of operating systems, different management modes are adopted to manage hardware and software resources in the respective equipment.
For example, according to the actual measurement situation, when the peripheral operating system is the mobile phone a of the first type operating system and the application is in the background mode to perform bluetooth broadcasting, the mobile phone B of the central operating system of the first type is in a state of being unable to scan and unable to normally acquire data. The central terminal operating system is a mobile phone C of a second type operating system, and cannot be scanned and data cannot be normally acquired in a black screen state. If the mobile phone D with the central operating system being the first type of operating system performs global scanning, the data cannot be normally acquired. The central terminal operating system is a mobile phone E of a second type operating system, and if a service UUID of the peripheral terminal is adopted for directional scanning, data cannot be normally acquired.
The Service UUID (Service Universally Unique Identifier, service distinguishing code) is a Service distinguishing code used when the peripheral end (data sending end) performs bluetooth broadcasting, and the length of the Service distinguishing code is generally 16 bits, and is generally expressed as 4 hexadecimal characters, such as 'FE 35'. The center (data receiving end) uses the Bluetooth scanning with Service UUID as directional scanning, and can only scan the Bluetooth broadcasting information with Service UUID; the central end (data receiving end) uses the Bluetooth scanning without Service UUID as global scanning, and can scan all Bluetooth broadcast information around the central end (data receiving end).
In an embodiment of the present disclosure, a bluetooth communication method is provided first, which overcomes at least to some extent the above-mentioned drawbacks of the related art.
The bluetooth communication method provided by the embodiment of the disclosure may be executed by a server, for example, the server obtains whether an application of a data transmitting end is in a background mode, and if so, screen brightness of a data receiving end is detected; and under the condition that the screen brightness of the data receiving end is larger than zero, carrying out relevant processing according to the system type of the data receiving end and the service distinguishing code of the data sending end so that the data receiving end can receive Bluetooth data sent by the data sending end.
The bluetooth communication method provided by the embodiment of the disclosure may also be executed by a mobile terminal serving as a data receiving end in bluetooth communication. Fig. 1 is a schematic flow chart of a bluetooth communication method according to an exemplary embodiment of the present disclosure, where the bluetooth communication method provided in the present embodiment is applied to a terminal device as a data receiving end in a bluetooth communication process. Referring to fig. 1, the method includes:
Step S110, detecting the screen brightness of a data receiving end in response to the application of the data transmitting end being in a background mode;
Step S120, judging whether the screen brightness of the data receiving end is larger than zero; and
And under the condition that the screen brightness of the data receiving end is larger than zero, executing step S130, and receiving Bluetooth data sent by the data sending end based on the system type of the data receiving end and the service distinguishing code of the data sending end.
In the technical scheme provided in the embodiment shown in fig. 1, when the application of the data sending end is in the background mode, firstly, the screen brightness of the data receiving end is detected, and then, when the screen brightness is judged to be greater than zero, bluetooth data is received based on the system type of the data receiving end and the service UUID of the data sending end. Therefore, the problem that Bluetooth data cannot be scanned and received when the application of the data transmitting end is in a background mode is solved.
In an exemplary embodiment, the data transmitting terminal refers to a mobile terminal installed with a first type of operating system. Therefore, the technical scheme can effectively solve the problem that Bluetooth data cannot be scanned and received by other terminals when the application of the mobile terminal provided with the first type of operating system is in a background mode.
In an exemplary embodiment, the application of the data sending end is in a background mode, which includes the following situations: the data transmitting end is in a desktop state, other applications installed on the data transmitting end are in a foreground mode, and the data transmitting end is in a black screen state. The foreground mode refers to a state that a target App in the mobile terminal is in a full-screen running state or is directly used by a user.
That is, the target application for bluetooth communication is not running in the foreground of the data transmitting end. Referring to fig. 2, for example, a user wishes to share voice played in the multimedia playing software A1 installed in the data transmitting terminal 21 to other terminals (e.g., the terminal 22 installed with the second type of operating system and the terminal 23 installed with the first type of operating system) through bluetooth, but the multimedia playing software A1 is in a background mode, e.g., the data transmitting terminal 21 is in a desktop state, other applications B1 installed in the data transmitting terminal 21 are in a foreground mode, or the data transmitting terminal 21 is in a black screen state. From the foregoing, it can be seen that the terminal 23 with the first type of operating system is in a black screen state and cannot normally acquire the voice data shared by the data transmitting end 21, and the terminal 22 with the second type of operating system is in a black screen state and cannot normally acquire the data. The following describes a specific technical solution to solve this technical problem:
In an exemplary embodiment, in response to an application of the data transmitting end being in a background mode, when the data receiving end cannot scan the target bluetooth data, exemplary, the screen brightness of the data receiving end is detected. In order to realize that bluetooth data is smoothly scanned and received by a data receiving end, the data receiving end needs to be periodically on-screen processed. That is, if the screen brightness of the signal receiving end is equal to zero, step S140 is performed: and the screen brightness of the data receiving end is larger than zero by calling the application interface of the local notification.
In an exemplary embodiment, the manner in which the bright screen is processed may be by directly calling an API (Application Programming Interface, application program interface) to implement the bright screen. For mobile terminals with installed first type operating systems, which do not include directly callable APIs to realize bright screens, a local notification API may be called. For example, sending a local notification message may implement a bright screen at the data receiving end. However, to avoid the local notification message from disturbing the user, the API may be called again for revocation after a short period of time (e.g., no more than 1 second). Wherein, the local notification refers to the notification bar message which is directly sent by the App in the first type operating system or the second type operating system is the local notification; correspondingly, the notification bar message sent by the back-end server of the App is a remote notification.
After the screen-lighting process, the data receiving end performs bluetooth scanning to scan the bluetooth data broadcasted by the data transmitting end and realize data reading.
In an exemplary embodiment, after the bright screen process, the scan receiving manner of the bluetooth data is different according to the operating system. Fig. 3 is a flowchart illustrating a method for receiving bluetooth data according to an embodiment of the present disclosure, and referring to fig. 3, the method includes the following steps:
In step S310, the operation type of the data receiving end is determined. If the operation system is the same as the data sending end and the first type of operation system is the same as the data sending end, step S320 is executed, and directional scanning is performed based on a service UUID of the data sending end for sending the bluetooth data, so as to obtain the bluetooth data sent by the data sending end. Referring to fig. 2, that is, for the terminal 23 mounted with the first type of operating system, if its screen brightness is greater than zero (indicating a non-black screen state), bluetooth scanning may be performed by a directional scanning method with a Service UUID. The Service UUID broadcasts a Service UUID of bluetooth data for the data transmitting terminal 21. Through the directional scanning, the terminal 23 can receive the voice played in the multimedia playing software A1 in the data transmitting end 21.
Therefore, even if the application of the data transmitting end is in the background mode, the data receiving end provided with the first type operating system can successfully receive the Bluetooth data based on the technical scheme, so that the technical problem that in the related art, when the device provided with the first type operating system is used as the data transmitting end and the related application of the device is used for Bluetooth broadcasting in the background mode, the device of the same type operating system as the data transmitting end cannot successfully receive the Bluetooth data is solved.
In an exemplary embodiment, if the data receiving end is installed with a second type of operating system different from the data transmitting end, steps S330-S360 are performed.
In step S330, the data receiving end performs global scanning to obtain a bluetooth packet. Since the data receiving end performs scanning without the service UUID, the data receiving end will scan all bluetooth broadcast information around the terminal. Further, these bluetooth broadcast information needs to be screened to obtain bluetooth data sent by the data sending end. In this embodiment, the bluetooth packet (i.e., all bluetooth broadcast information around the terminal) is screened (denoted as "second screening") by determining whether the identifier of the data transmitting end is included in the bluetooth packet.
Referring to fig. 3, in step S340, it is determined whether the bluetooth packet includes an identifier of the data transmitting end. And discards the bluetooth data that does not include the identifier of the data transmitting end, that is, step S360 is performed: discarding the current Bluetooth data packet and processing the next Bluetooth data packet. Therefore, the number of Bluetooth data after global scanning is effectively reduced, the speed of determining target Bluetooth data is increased, and the data processing efficiency is improved.
In an exemplary embodiment, the bluetooth data containing the identifier of the data sender is further screened (denoted as "first screening"). Namely, step S350 is performed: and performing first screening on the Bluetooth data packet according to the service UUID of the data transmitting end so as to obtain Bluetooth data sent by the data transmitting end.
For example, fig. 4 shows a schematic flow chart of performing the first screening according to an embodiment of the disclosure, and referring to fig. 4, an embodiment of performing the first screening may include:
Step S410, determining the position information of the target character according to the service UUID of the data transmitting end to obtain standard position information; step S420, obtaining the position information of the target character in the Bluetooth data packet to obtain candidate position information; and step S430, screening the Bluetooth data packet by comparing the standard position information with the candidate position information.
In an exemplary embodiment, when the data transmitting end is provided with the first type of operating system and an application for performing bluetooth communication in the device is in a background mode, and meanwhile, the data receiving end is a device of a different type of operating system from the data transmitting end, a specific implementation manner of corresponding bluetooth communication is as follows (i.e., a specific implementation manner of step S330-step S360):
1. The data receiving end with the second type of operating system installed performs global scanning, and the called API will obtain a binary bluetooth packet (step S330). The binary data may first be converted into hexadecimal string format.
Referring to fig. 5, a hexadecimal string of a certain bluetooth packet, for example, may be expressed as "02011A020A0C0BFF4C001006031E2B5BA39F0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000".
2. In the hexadecimal string for representing the bluetooth packet obtained in the previous step, it is determined whether the identifier of the data transmitting end is included (step S340). For example, the identifier of the data transmitting end may be denoted as "FF4C001", and then whether the sub-string "FF4C001" is included in the hexadecimal string for representing the bluetooth packet is searched.
In an exemplary embodiment, the bluetooth packet includes an identifier of the transmitting end (i.e., the sub-string) to indicate that the bluetooth packet is bluetooth data broadcasted by the transmitting end, and further, in view of the fact that when the application performs bluetooth broadcasting in the background mode, the bluetooth broadcast data is placed in a special overflow area of the transmitting end, the overflow area is further located in the string to obtain the target bluetooth data.
The manner of positioning the overflow area in this embodiment is: the data in the overflow area in the hexadecimal character string of the Bluetooth data packet is as follows: 006031E2B5BA39F00000000000000000. Further, the content of the overflow area is further filtered according to the service UUID of the data sending end (step S350).
Still taking the bluetooth packet listed in the previous step as an example, the identifier "FF4C001" at the data transmitting end is followed by 32 characters of "006031E2B5BA39F00000000000000000".
For example, if no other character or the number of characters does not reach 32 bits after the identifier of the sender (i.e., the above-mentioned substring) in the bluetooth packet, it is indicated that the overflow (overflow) area has no valid information. I.e., after "FF4C001", there is no 32-bit character, the bluetooth packet is screened out, and the next bluetooth packet is continued to be processed (step S360). Therefore, the number of Bluetooth data is further reduced, the speed of determining target Bluetooth data is increased, and the data processing efficiency is improved.
3. In view of the fact that the service UUID of the data sending terminal for bluetooth broadcasting may be used to uniquely determine the broadcast bluetooth data, the embodiment may further screen the data in the overflow area scanned by the data receiving terminal according to the service UUID of the data sending terminal.
For example, in this embodiment, the binary character "1" is used as the target character, and the character of the overflow (overflow) area is represented as a binary form. For example, the 32 characters of the overflow area acquired in the previous step are converted into a binary string, and referring to fig. 5, the binary string is obtained as "11000000011000111100010101101011011101000111001111100000000000000000000000000000000000000000000000000000000000000000000".
In addition, the location information of the target character "1" in the service UUID of the data transmitting end performing bluetooth broadcasting is determined as the standard location information (step S410). For example, if the service UUID is "CAFE," bit 37 is "1".
4. The positions of all target characters '1' in the binary string obtained in the previous step (namely, the binary string obtained according to the overflow area conversion) are obtained to obtain candidate position information (step S420), and the standard position information is further compared with the candidate position information (step S430) to judge whether the position of '1' in the binary string obtained by the overflow area conversion is the same as the position of '1' in the corresponding service UUID. If the data packets are the same, the Bluetooth data packets are indicated to be the data to be received; otherwise, the current Bluetooth data packet is abandoned, and the next Bluetooth data packet is processed continuously.
For example, the above target character is still exemplified by the two-level system character "1", and the present embodiment provides a method for obtaining the target character and its position information (standard position information):
1) Installing an application for sharing information through Bluetooth communication on a mobile phone (a data sending end) provided with a first type of operating system, starting Bluetooth broadcasting, and enabling the application to be in a background mode, for example, the mobile phone can be placed in a black screen state. And ensures that no other devices in the surrounding environment of the handset are conducting bluetooth broadcasts.
2) Connecting the operating handset with the second type to the computer, starting the application on the handset (data receiving end) using the Debug mode, and starting the bluetooth scanning function. At the position of reading Bluetooth broadcast signal codes, the read data is converted into hexadecimal character strings, and the character strings are extracted (the breakpoint debugging function or direct screen printing can be realized).
