[0033] Example 1

[0034] The method embodiment provided in the first embodiment of the present invention can be executed in a television, a mobile phone, a computer or a similar computing device. Taking running on a television as an example, Figure 1 FIG. 1 is a hardware structure diagram of a television set according to an embodiment of the present invention. Figure 1 As shown, the television may include one or more ( Figure 1Only one is shown) a processor 61 (the processor 61 may include but is not limited to a microprocessor MCU or a programmable logic device FPGA and other processing devices) and a memory 63 for storing data.

It will be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned television. Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0035] The memory 63 can be used to store television programs, for example, software programs and modules of application software, such as a television program corresponding to a method for displaying a Bluetooth list in an embodiment of the present invention. The processor 61 executes various functional applications and data processing by running the television program stored in the memory 63, thereby realizing the above-mentioned method. The memory 63 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0036] Transmission device 116 is used to receive or transmit data via a network.

In one embodiment, transmission device 116 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, transmission device 116 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0037] In this embodiment, a method for displaying a Bluetooth list is provided. Figure 2 is a flow chart of a method for displaying a Bluetooth list according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0038] Step S202: receiving discovery signals broadcast by several Bluetooth devices;

[0039] The solution of this embodiment can be applied to network terminals such as televisions, mobile phones, and computers. A television is used as an example for illustration. After a scanning device receives a discovery signal broadcast by any Bluetooth device, it can detect and confirm the existence of the Bluetooth device and can continue to initiate a Bluetooth communication connection with the Bluetooth device.

[0040] Step S204: Calculate the frequency information of each Bluetooth device broadcasting a discovery signal, wherein the frequency information is used to represent the activity of the corresponding Bluetooth device;

[0041] When a Bluetooth device is broadcasting a discovery signal, the more times a scanning device receives the discovery signal within a fixed time, the more active the Bluetooth device is. This is because the farther the Bluetooth device is from the scanning device, or the more unstable the Bluetooth device is (device location, communication quality, etc.), the scanning device will fail to receive the discovery signal, which will lead to a decrease in the number of discovery signals received within a fixed time and a lower frequency.

[0042] Step S206: Displaying a plurality of Bluetooth devices in the Bluetooth interface of the scanning device in descending order of frequency information;

[0043] In the Bluetooth interface to be connected in this embodiment, multiple unconnected Bluetooth devices can be displayed, and the frequency information is used to sort and display them. The user can find the most active Bluetooth device in time and trigger the connection.

[0044] Through the above steps, the discovery signals broadcast by several Bluetooth devices are received; the frequency information of the discovery signals broadcast by each Bluetooth device is calculated, wherein the frequency information is used to characterize the activity of the corresponding Bluetooth device, and several Bluetooth devices are displayed in the Bluetooth interface to be connected of the scanning device in descending order of the frequency information. By calculating the frequency information of the received discovery signals, the activity of each Bluetooth device to be connected can be determined, and then the user can be displayed and prompted in the Bluetooth interface to be connected of the scanning device. New devices with high activity can be discovered in time, which simplifies the process of connecting new Bluetooth devices, solves the technical problem of the related technology of lagging in discovering new Bluetooth devices, avoids the lag in identifying new devices, and improves the efficiency of human-computer interaction.

[0045] In one implementation of this embodiment, calculating the frequency information of each Bluetooth device broadcasting a discovery signal includes:

[0046] S11, reading a cache list in the memory of the scanning device, wherein the cache list is used to record the broadcast time and broadcast frequency of discovery signals broadcast by several Bluetooth devices;

[0047] Optionally, the broadcast time of this embodiment includes two situations. One is that the broadcast time includes: the first broadcast time and the last broadcast time; the other is that the broadcast time includes the time each time a Bluetooth device broadcasts a discovery signal, and the number of broadcasts is the same as the number of times the scanning device receives the discovery signal.

[0048] S12: For each Bluetooth device, calculate the frequency information of the broadcast discovery signal using the corresponding broadcast time and broadcast times.

[0049] In some examples, the target Bluetooth device is any Bluetooth device among several Bluetooth devices, and the frequency information of broadcasting discovery signals is calculated using the corresponding broadcast time and broadcast number, including: obtaining the first broadcast time and the last broadcast time of the target Bluetooth device broadcasting the discovery signal within the scanning period from the cache list, and obtaining the number of broadcasts of the target Bluetooth device broadcasting the discovery signal within the scanning period from the cache list; calculating the broadcast duration based on the time difference between the last broadcast time and the first broadcast time; dividing the broadcast duration by the broadcast number to obtain the frequency information of the target Bluetooth device broadcasting the discovery signal within the scanning period.

[0050] For example, the cache list includes multiple columns, each column corresponds to a Bluetooth device, and is identified by the name of the Bluetooth device. Each column includes three data items: first broadcast time, last broadcast time, and number of broadcasts. The last broadcast time and number of broadcasts are dynamically updated and updated once each time a discovery signal is received during a scanning cycle. If only one discovery signal is received during a scanning cycle, the end time of the scanning cycle is configured as the last broadcast time.

[0051] In another example, the frequency information of broadcast discovery signals is calculated using the corresponding broadcast time and broadcast number, including: obtaining the time series of the target Bluetooth device broadcasting the discovery signal during the scanning period from the cache list, and determining the number of elements of the time series as the broadcast number; reading the last broadcast time and the first broadcast time from the time series, and calculating the broadcast duration based on the time difference between the last broadcast time and the first broadcast time; dividing the broadcast duration by the broadcast number to obtain the frequency information of the target Bluetooth device broadcasting the discovery signal during the scanning period.

[0052] The time sequence of this embodiment is used to store the timestamp of each time the target Bluetooth device broadcasts a discovery signal, and can be arranged in a chronological order, such as [time 1, time 2, time 3]. The time sequence includes 3 elements, so the number of broadcasts is 3, and the last broadcast time and the first broadcast time are time 3 and time 1 respectively.

[0053] By performing the same process as above on each Bluetooth device, the frequency information of each Bluetooth device can be calculated.

[0054] In one implementation of this embodiment, before calculating the frequency information of each Bluetooth device broadcasting the discovery signal, it also includes: after receiving the first discovery signal, parsing the first device identifier carried by it from the discovery signal, and recording the reception time, wherein the first device identifier is used to identify the first Bluetooth device; judging whether the first device identifier exists in the cache table of the current scanning cycle; if the first device identifier exists in the cache table of the current scanning cycle, using the reception time to update the last broadcast time of the first Bluetooth device, and the number of broadcasts is accumulated once; if the first device identifier does not exist in the cache table of the current scanning cycle, inserting the first device identifier in the cache table, and recording the reception time as the first broadcast time of the first Bluetooth device in the current scanning cycle, and the number of broadcasts is accumulated once.

[0055] In another implementation of this embodiment, the cache list is recorded through multiple time series, each time series corresponds to a Bluetooth device, and can be named using the device identifier of the Bluetooth device. Before calculating the frequency information of each Bluetooth device broadcasting the discovery signal, it also includes: after receiving the first discovery signal, parsing the first device identifier carried by it from the discovery signal, and recording the reception time, wherein the first device identifier is used to identify the first Bluetooth device; using the first device identifier to search for a matching first time series, and inserting the reception time at an adjacent position of the last element of the first time series to update the first time series.

[0056] For example, before receiving, the first time sequence is [time 1, time 2]. The first discovery signal is received at time 3. By parsing the device identifier "device 1", the first time sequence is matched, and time 3 is inserted after time 2 to update [time 1, time 2, time 3].

[0057] In one implementation of this embodiment, displaying several Bluetooth devices in the Bluetooth interface to be connected of the scanning device in descending order of frequency information includes: sorting the device identifiers of the several Bluetooth devices in descending order according to the frequency information to obtain a device sequence; and displaying the device sequence in the Bluetooth interface to be connected of the scanning device.

[0058] In an example, the current environment includes three Bluetooth devices, namely device 1, device 2, and device 3. The corresponding frequency information is 3 times / 10 seconds, 7 times / 10 seconds, and 12 times / 10 seconds, respectively. After sorting in descending order, the device sequence is [device 3, device 2, device 1]. The display order in the Bluetooth connection interface of the scanning device is device 3, device 2, and device 1. The user can select the most active device 3, followed by device 2 and device 1.

[0059] In some examples, after displaying several Bluetooth devices in the Bluetooth interface to be connected of the scanning device in descending order of frequency information, it also includes: detecting whether there are historical connection records for the several Bluetooth devices; if there are historical connection records for the second Bluetooth device; adding a record identifier to the associated position of the second Bluetooth device in the Bluetooth interface to be connected, wherein the record identifier is used to indicate that the second Bluetooth device has been connected to the scanning device before.

[0060] Optionally, the record identifier can be "historically connected device" or "familiar device". In addition, if there is no historical connection record for the third Bluetooth device, a reminder identifier is added to the associated position of the third Bluetooth device in the Bluetooth interface to be connected. The reminder identifier can be "unfamiliar device" or "new device", etc., to prompt the user to select the most appropriate and correct Bluetooth device from multiple Bluetooth devices to be connected.

[0061] In some examples, after displaying several Bluetooth devices in the Bluetooth interface to be connected of the scanning device in descending order of frequency information, it also includes: parsing the capability information and / or custom data of several Bluetooth devices from the discovery signal respectively; and adding the capability information and / or custom data to the associated position of each Bluetooth device in the Bluetooth interface to be connected.

[0062] Optionally, a device can be discovered by others. A device that doesn't broadcast its presence is invisible to surrounding devices. Therefore, to be discoverable, it must broadcast. This broadcast can include rich data, such as device capabilities, device name, and other custom data. This creates a second possibility. Broadcasting data to applications that don't require a connection. For example, a BLE thermometer can broadcast its temperature without accepting any connections. A detector can simply listen for the broadcast to obtain the current temperature.

[0063] The capability information of this embodiment can be used to characterize the network capability of the Bluetooth device (broadcasting the discovery signal), such as transmission distance, storage capacity, network quality (signal-to-noise ratio, bit error rate, etc.), motion status (moving, fixed, etc.), etc. The custom data is user-defined information of the Bluetooth device, such as "I am Zhang San", which can simultaneously identify the Bluetooth device with the device identifier, or it can be the battery level, device type (such as headphones, mobile phones, TVs). By adopting the method of this embodiment, while displaying the Bluetooth device, the recognition rate of the Bluetooth device is improved to prompt the user to select the most appropriate and correct Bluetooth device among multiple Bluetooth devices to be connected.

[0064] Figure 3 is a logical structure diagram of a scanning device according to an embodiment of the present invention. Figure 41 is a flowchart of a scanning device according to an embodiment of the present invention. The scanning device in this embodiment is a Bluetooth device 100, and the Bluetooth devices to be connected include other Bluetooth devices 104 to 106. The workflow includes:

[0065] S31, Bluetooth device A (Bluetooth device 100) turns on the device search function;

[0066] S32, continuously receiving broadcast information from other Bluetooth devices;

[0067] S33, Bluetooth device A maintains a cache list in memory, inserts or updates other Bluetooth devices found into the cache list, and records the insertion time, update time, and update count;

[0068] S34, subtract the insertion time from the update time, and divide the result by the number of updates to obtain the number of Bluetooth broadcasts received per unit time;

[0069] S35, sorting the cache list according to the number of Bluetooth broadcasts received per unit time;

[0070] S36, displaying the sorted column list through the display module;

[0071] The solution of this embodiment is adopted, and the devices are sorted according to the number of Bluetooth broadcasts received per unit time. The more broadcasts received, the more active the device is. No manual intervention is required, and there is no lag. The most active Bluetooth device can be displayed at the front every time.

[0072] Through the description of the above embodiments, those skilled in the art will clearly understand that the methods according to the above embodiments can be implemented using software plus the necessary general-purpose hardware platform. Of course, hardware can also be used, but in many cases the former is a more preferred embodiment. Based on this understanding, the technical solution of the present invention, or the portion that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, or optical disk) and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in various embodiments of the present invention.
