Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
The embodiment of the application provides a Bluetooth signal scanning method, bluetooth signal scanning equipment and a computer readable storage medium.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart of a bluetooth signal scanning method according to an embodiment of the present application. The Bluetooth signal scanning method can be used in a first device with a Bluetooth function to scan Bluetooth signals broadcast by a second device, wherein the first device and the second device can be terminal devices with the Bluetooth function. Specifically, the first device and the second device may be, for example, terminal devices such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, a personal digital assistant, and a wearable device.
Referring to fig. 2, fig. 2 is a usage scenario diagram of a bluetooth signal scanning method according to an embodiment of the present application. As shown in fig. 2, the first device and the second device both have bluetooth functions, the second device broadcasts bluetooth signals, when the first device turns on the bluetooth signal scanning function, the first device scans based on a first duty cycle, the duty cycle is adjusted to a second duty cycle according to the scanned bluetooth signals, and then the bluetooth signals of the second device are scanned based on the second duty cycle, so as to achieve an ideal bluetooth signal scanning effect.
As shown in fig. 1, the bluetooth signal scanning method includes steps S101 to S103.
Step S101, scanning Bluetooth signals of a second device based on a preset first duty ratio, and obtaining signal interval duration of the Bluetooth signals, wherein the signal interval duration is interval duration between two times of Bluetooth signals.
Illustratively, the bluetooth signal broadcast by the second device is scanned based on the first duty cycle, and a signal interval duration of the bluetooth signal is determined, so as to determine a second duty cycle adapted to the broadcasting period of the bluetooth signal according to the signal interval duration.
In some embodiments, the first duty cycle is greater than or equal to 90%.
For example, when the bluetooth signal starts to be scanned, the first duty cycle greater than or equal to the preset value is used for scanning, and the preset value may be set according to practical requirements, for example, the preset value may be set to 100%, which is not limited to this, and the preset value may be other values, which is not limited herein.
Illustratively, when the user turns on the bluetooth scanning function, the user aims to scan as much as possible for surrounding bluetooth signals. Therefore, a higher duty cycle can be set for scanning at this time, for example, the scanning is performed at a duty cycle of 100%, so that the time for scanning to the Bluetooth signal is shortened, and the user experience is improved. Also, since the time taken to scan the bluetooth signal based on the first duty ratio is short, scanning based on a higher duty ratio during this time is not likely to generate a larger power consumption.
In some embodiments, the scanning the bluetooth signal of the second device based on the preset first duty cycle, to obtain a signal interval duration of the bluetooth signal, includes: and if the Bluetooth signal is not scanned within the preset duration threshold, stopping scanning the Bluetooth signal of the second equipment based on the first duty ratio.
For example, in the case of scanning at the first duty cycle, if no bluetooth signal is scanned within the duration threshold, this indicates that the second device may have stopped broadcasting bluetooth signals at this time, or that the second device has left the range that the first device can scan for. To prevent the power consumption of the first device from unnecessarily increasing due to the continuous scanning based on the first duty cycle, the scanning of the bluetooth signal of the second device based on the first duty cycle is stopped if no bluetooth signal is scanned within the duration threshold.
The stopping of the scanning of the bluetooth signal of the second device based on the first duty cycle may be, for example, adjusting to scan based on a lower duty cycle, or may be, without limitation, turning off the scanning function.
In some embodiments, the scanning the bluetooth signal of the second device based on the preset first duty cycle, to obtain a signal interval duration of the bluetooth signal, includes: and scanning Bluetooth signals of the second equipment based on a preset first duty ratio, and acquiring at least two signal interval time lengths from the termination time of the first scanned Bluetooth signal.
In an exemplary embodiment, when the first device turns on the scanning function to scan the bluetooth signal of the second device based on the first duty cycle, the first device cannot determine whether the scanned first bluetooth signal is a complete bluetooth signal, and discards the scanned first bluetooth signal. It will be appreciated that if the first device starts scanning for bluetooth signals by turning on the scanning function during the broadcast of bluetooth signals by the second device, the duration of the scanned first bluetooth signal is not the full signal duration.
Referring to fig. 3, fig. 3 is a timing chart of a bluetooth signal broadcast by the second device and a bluetooth signal scanned by the first device.
As shown in fig. 3, the second device broadcasts bluetooth signals with adjacent signal duration and signal interval duration as broadcast periods, if the first device starts scanning bluetooth signals at time t, the scanned duration of the first bluetooth signal will not be the complete signal duration, and the scanned first bluetooth signal needs to be discarded. Therefore, the duration from the ending time of the first bluetooth signal to the starting time of the second bluetooth signal is taken as the first signal interval duration, the duration from the ending time of the second bluetooth signal to the starting time of the third bluetooth signal is taken as the second signal interval duration, and so on, and no description is given here.
Step S102, determining a second duty ratio for scanning Bluetooth signals of the second equipment according to the signal interval duration.
The scanning period for scanning the bluetooth signal based on the second duty ratio includes an adjacent scanning period and a rest period, and according to the acquired signal interval duration, the second duty ratio adapted to the bluetooth signal broadcasting period of the second device is determined, and the scanning is performed based on the second duty ratio, so that the scanning effect of the bluetooth signal is improved.
In some embodiments, the determining, according to the signal interval duration, a second duty cycle for scanning bluetooth signals of the second device includes: and if at least two sections of signal interval time lengths meet a preset condition, determining the scanning time period time length of the second duty ratio according to the at least two sections of signal interval time lengths.
For example, when the first device scans the bluetooth signal sent by the second device, there may be interference caused by multiple factors, and after two or more signal interval durations are acquired, the obtained signal interval duration is determined based on a preset condition, so as to determine whether the signal interval duration is a complete duration, thereby improving accuracy of subsequent determination of the second duty ratio.
In some embodiments, the at least two signal interval durations include a first signal interval duration, a second signal interval duration; if the signal interval duration of at least two segments meets the preset condition, determining the scanning period duration of the second duty ratio according to the signal interval duration of at least two segments includes: and if the difference between the first signal interval duration and the second signal interval duration is smaller than a preset maximum delay duration, determining the scanning period duration according to the first signal interval duration and the second signal interval duration.
Taking two signal interval durations as an example, the obtained signal interval duration is judged according to whether the first signal interval duration and the second signal interval duration meet preset conditions.
For example, in order to prevent continuous collision between bluetooth signals transmitted by different devices, existing bluetooth communication protocols randomly increase a delay period over a preset broadcasting interval period when broadcasting bluetooth signals. Wherein the delay period is not greater than a preset maximum delay period. For example, a delay period of 0 to 10ms is randomly increased over a predetermined broadcasting interval period, and the maximum delay period at this time is 10ms.
It will be appreciated that since the first signal interval duration and the second signal interval duration are each a delay duration that is not greater than 10ms added to the preset broadcast interval duration, the difference between the first signal interval duration and the second signal interval duration should be less than 10ms.
For example, if the difference between the acquired first signal interval duration and the second signal interval duration is smaller than the maximum delay duration, which means that the first signal interval duration and the second signal interval duration are matched after considering the influence caused by the random delay duration, that is, the first signal interval duration and the second signal interval duration are both complete signal interval durations, the scanning period duration in the second duty cycle may be determined according to the acquired first signal interval duration, the second signal interval duration and the preset maximum delay duration.
Referring to fig. 4, fig. 4 is a usage scenario diagram of a bluetooth signal scanning method according to an embodiment of the present application.
As shown in fig. 4, in some embodiments, the determining the scanning period duration according to the first signal interval duration and the second signal interval duration includes: step S1021, determining the smaller of the first signal interval duration and the second signal interval duration as a target signal interval duration; step S1022, determining the scanning period duration according to the sum of the target signal interval duration and the maximum delay duration.
Illustratively, the first signal interval duration and the second signal interval duration obtained by the first device scanning are generally unequal due to the random delay time durations, and the broadcast interval duration of the second device needs to be approximately determined according to the first signal interval duration and the second signal interval duration, so as to determine the scanning period duration of the first device scanning based on the second duty cycle according to the approximate broadcast interval duration.
For example, the smaller of the first signal interval duration and the second signal interval duration is determined as the target signal interval duration, and the sum of the target signal interval duration and the maximum delay duration is determined as the approximate broadcast interval duration.
Of course, the approximate broadcast interval duration is not limited thereto, and the approximate broadcast interval duration may be determined by determining the larger of the first signal interval duration and the second signal interval duration as the target signal interval duration, and determining the difference between the target signal interval duration and the maximum delay duration as the approximate broadcast interval duration, which is not limited thereto.
For example, for the second device, the bluetooth signal broadcasting period includes a broadcasting duration in which bluetooth signal broadcasting is performed and a broadcasting interval duration in which bluetooth signal broadcasting is not performed, and the broadcasting interval duration is generally much longer than the broadcasting duration. Therefore, as long as the scanning period of the first device for scanning is longer than the broadcasting interval duration of the second device, the scanning period duration of the first device can be ensured to cover the broadcasting duration of the second device, and further the first device can be ensured to scan the Bluetooth signal of the second device within the scanning period duration.
Therefore, according to the determined approximate broadcast interval duration, the scanning period duration larger than the approximate broadcast interval duration is determined, and the first device can be ensured to scan Bluetooth signals of the second device in the scanning period duration.
In some embodiments, the determining the scan period duration according to a sum of the target signal interval duration and the maximum delay duration includes: determining the scanning period duration according to a preset first time duration coefficient, the sum of the target signal interval duration and the maximum delay duration; wherein the first time length coefficient is greater than 1.
Illustratively, the sum of the target signal interval duration and the maximum delay duration is multiplied by a first time duration coefficient greater than 1 to obtain a scan time duration.
For example, the first time length coefficient may be determined according to actual requirements, for example, the first time length coefficient may be 1.5, that is, the scanning period duration is 1.5 times of the sum of the target signal interval duration and the maximum delay duration, which is not limited thereto.
In some embodiments, the determining, according to the signal interval duration, a second duty cycle for scanning bluetooth signals of the second device further includes: determining the rest period duration of the second duty ratio according to a preset second duration coefficient and the scanning period duration; wherein the second duration coefficient is greater than 0.
The scan period of the second duty cycle includes an adjacent scan period duration and rest period duration.
The rest period duration may be less than or equal to the scan period duration, or may be greater than the scan period duration. Specifically, when the second duration coefficient is greater than 0 and less than or equal to 1, the rest period duration is less than or equal to the scan period duration; when the second duration coefficient is greater than 1, the rest period duration is greater than the scanning period duration.
In some embodiments, the second duration factor is greater than 0 and less than or equal to 1 when the first device is in the first scanning mode; the second duration factor is greater than 1 when the first device is in the second scan mode.
When the opposite-end broadcast of the second device needs to be frequently acquired, the first device is set to a first scanning mode, and at the moment, the second duration coefficient is greater than 0 and less than or equal to 1, that is, the rest period duration is less than or equal to the scanning period duration, and at the moment, the second duty ratio is larger; when the requirement on the acquisition frequency of the Bluetooth signal broadcast of the second device is not high, the first device is set to a second scanning mode, at the moment, the second time length coefficient is larger than 1, namely the rest period time length is longer than the scanning period time length, and at the moment, the second duty ratio is smaller.
By setting different scanning modes, the flexibility of Bluetooth signal scanning is improved, so that the first device can adjust scanning power consumption according to actual requirements, and the use experience of a user for Bluetooth signal scanning through the first device is improved.
Step S103, scanning the bluetooth signal of the second device based on the second duty cycle.
In an exemplary embodiment, the second duty cycle is smaller than the first duty cycle, and the scan period for scanning the bluetooth signal based on the second duty cycle includes adjacent scan periods and rest periods.
The duty ratio of the first device is adjusted, the duty ratio of the first device is adjusted from the preset first duty ratio to the second duty ratio, and the bluetooth signal of the second device is scanned based on the second duty ratio, so that the scanning period corresponds to the broadcast event, and the scanning effect of the bluetooth signal is improved.
For example, the first device starts a bluetooth scanning function, scans bluetooth signals of the second device based on a duty cycle of 100%, determines a duration from a termination time of the scanned first bluetooth signal to a start time of the second bluetooth signal as a first signal interval duration, determines a duration from a termination time of the scanned second bluetooth signal to a start time of the third bluetooth signal as a second signal interval duration, and so on. If the difference between the first signal interval duration and the second signal interval duration is smaller than the maximum delay duration, the first signal interval duration and the second signal interval duration are considered to be complete signal interval durations, and the smaller one of the first signal interval duration and the second signal interval duration is added with the maximum delay duration to obtain the approximate broadcast interval duration. Multiplying the preset first time length coefficient by the approximate broadcast interval duration to obtain the scanning time period duration of the second duty ratio. And determining the scanning interval duration of the second duty ratio according to the product of the second duration coefficient and the scanning period duration.
According to the Bluetooth signal scanning method, bluetooth signals of the second device are scanned based on the preset first duty ratio, so that signal interval duration of the Bluetooth signals is obtained, wherein the signal interval duration is interval duration between two times of Bluetooth signals; determining a second duty cycle of scanning Bluetooth signals of the second equipment according to the signal interval duration; and scanning Bluetooth signals of the second device based on the second duty cycle. And determining a second duty ratio of the subsequent scanning of the Bluetooth signal by the signal interval duration of the Bluetooth signal obtained by scanning based on the first duty ratio, so that the scanned duty ratio corresponds to the period of the Bluetooth signal broadcast, and the efficiency of the Bluetooth signal scanning is improved.
