Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a device connection method for a first device located in a terminal according to an exemplary embodiment, wherein the first device may be any bluetooth-enabled device such as a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a smart speaker, and the like. As shown in FIG. 1, the method includes the following steps S11-S12.
In step S11, acquiring a preset parameter value between the first device and the second device; wherein the preset parameter value includes at least one of a received signal strength indication value and a distance.
In step S12, a bluetooth connection state with the second device is controlled according to a preset parameter value.
By adopting the technical scheme provided by the embodiment of the disclosure, the Bluetooth connection state between the first device and the second device can be controlled according to the preset parameter value between the first device and the second device, so that the first device can automatically control the Bluetooth connection state between the first device and the second device according to the received signal strength indicated value or the distance, and therefore, signals transmitted by Bluetooth between the devices are better, and the user experience is improved.
In the above embodiments, according to different preset parameter values, the manner in which the first device controls the bluetooth connection state with the second device is also different. How the first device controls the bluetooth connection state with the second device according to different preset parameter values is described below by embodiments, respectively.
In one embodiment, when the preset parameter value includes a received signal strength indicator value, as shown in fig. 2, the step S12 may be performed as the following steps S21-S23.
In step S21, determining whether the received signal strength indicator value with the second device is smaller than a preset threshold value; if the received signal strength indicator value with the second device is smaller than the preset threshold value, executing step S22; if the received signal strength indicator value with the second device is greater than or equal to the preset threshold value, step S23 is performed.
In step S22, the bluetooth connection with the second device is disconnected.
In step S23, a bluetooth connection is established with the second device.
Among them, the RSSI (Received Signal Strength Indication) value is the indicated value of the Received Signal Strength. The larger the received signal strength indicating value is, the stronger the signal strength of the first device receiving the second device is, otherwise, the smaller the received signal strength indicating value is, the weaker the signal strength of the first device receiving the second device is, at this time, if the first device is still connected to the second device, the received signal is likely to be unstable, which affects the user experience.
For example, the preset threshold is set to-80 dBm, and the RSSI value of the first device relative to the second device may be changed by the interference of the external environment, for example, when the distance is changed, the RSSI value is also changed accordingly. The first device can monitor the RSSI value relative to the second device at any time, and the RSSI value is assumed to be-100 dBm, and the Bluetooth connection between the first device and the second device is disconnected because the RSSI value is smaller than a preset threshold value of-80 dBm. Similarly, assuming that the monitored RSSI value is-70 dBm, the first device establishes a bluetooth connection with the second device since the RSSI value is greater than the preset threshold value of-80 dBm.
In addition, in the implementation, in order to enhance the signal of the second device received by the first device, a signal constant may be added based on a predetermined threshold, so as to raise a threshold for establishing the bluetooth connection between the first device and the second device. The signal constant may also be measured according to an actual scene, for example, on the premise that the first device and the second device are separated by a certain distance and no obstacle exists between the first device and the second device, the signal strength value of the second device received by the first device through bluetooth at this time is determined as the signal constant.
For example, if the predetermined threshold is-90 dBm and the signal constant is-20 dBm, the first device controls the bluetooth connection state with the second device, and the reference value is-90 dBm-20dBm, that is, -70 dBm.
In this embodiment, the preset threshold may be pre-trained by the first device. As shown in FIG. 3, the method of training the preset threshold may include the following steps S31-S33.
In step S31, a threshold location from the second device is determined based on the fluency at which the first device receives signals from the second device at different locations.
The critical position is a position where the signal received by the first device can be smoothed. The signals of the second device can be received at a plurality of different positions respectively, the fluency of the received signals at each position is recorded, and then the critical position is selected according to the fluency of the received signals at each position.
In step S32, a received signal strength indicator value of the critical position is detected.
In this step, the method for detecting the RSSI value of a certain location is the prior art, and therefore is not described in detail.
In step S33, the received signal strength indicator value of the critical position is determined as a preset threshold value.
In this embodiment, the connection can be disconnected when the received signal strength indicated value between the first device and the second device is smaller than the preset threshold value, and the connection can be established when the received signal strength indicated value between the first device and the second device is greater than or equal to the preset threshold value, so that the first device can automatically control the bluetooth connection state between the first device and the second device according to the received signal strength indicated value, thereby making signals transmitted between the devices through bluetooth better, and avoiding the situation that the received signals are not smooth when the signal strength is poor.
In one embodiment, when the preset parameter values include distances, as shown in FIG. 4, step S12 may be performed as steps S41-S43 below.
In step S41, it is determined whether the distance with respect to the second device is equal to or greater than a preset distance; if the distance with respect to the second device is equal to or greater than the preset distance, performing step S42; if the distance with respect to the second device is less than the preset distance, step S43 is performed.
In step S42, the bluetooth connection with the second device is disconnected.
In step S43, a bluetooth connection is established with the second device.
In this embodiment, the smaller the distance between the first device and the second device is, the stronger the signal strength of the second device is received by the first device, whereas the larger the distance between the first device and the second device is, the weaker the signal strength of the second device is received by the first device is, at this time, if the first device is still connected to the second device, the received signal is likely to be unstable, which affects the experience of the user.
For example, the preset distance is set to 5m, and the first device can monitor the distance relative to the second device at any time, and assuming that the monitored distance is 10m, the first device disconnects the bluetooth connection with the second device because the distance value is greater than the preset distance of 5 m. Similarly, assuming that the monitored distance is 4m, the first device establishes a bluetooth connection with the second device because the distance is less than the preset distance 5 m.
In this embodiment, the preset distance may be determined in advance according to the fluency of the signal received by the first device from the second device at different locations, in a similar manner to the above-mentioned determination of the preset threshold: first, a threshold distance from the second device is determined, which is just a distance that allows the first device to smoothly receive the signal of the second device.
In this embodiment, the first device can disconnect when the distance to the second device is equal to or greater than the preset distance, and establish connection when the distance to the second device is less than the preset distance, so that the first device can automatically control the bluetooth connection state with the second device according to the distance to the second device, thereby making signals transmitted by bluetooth between the devices better, and avoiding the situation that the received signals are not smooth when the distance is too far.
In one embodiment, after performing step S22 or step S42, the method further comprises the steps of: when the Bluetooth connection with the second equipment is disconnected, prompt information is sent out, and the prompt information is used for prompting the reason why the Bluetooth connection is disconnected.
The first device may send the prompt message in various manners such as voice output and screen display, for example, the first device outputs the prompt message "the current distance is too far, the bluetooth connection is disconnected"; alternatively, the first device displays a prompt message "the current distance is too far, the bluetooth connection is disconnected" on its screen. The user can know the reason why the Bluetooth connection cannot be established currently through the prompt message, and then take corresponding measures according to the reason to enable the first device and the second device to be reestablished. For example, when the first device outputs the prompt message "the current distance is too far and the bluetooth connection is disconnected", the user may close the distance between the first device and the second device so that the distance is smaller than the preset distance, thereby reestablishing the bluetooth connection between the first device and the second device.
In the embodiment, the prompt information can be sent to the user when the Bluetooth connection between the devices is disconnected, so that the user can make accurate judgment according to the prompt information, and then take corresponding measures to reconnect the devices, thereby bringing convenience to the user.
In the device connection method provided by the embodiment of the present disclosure, the first device and the second device may be any devices having a bluetooth function. The device connection method is described below by way of a specific scenario.
In a specific embodiment, the first device is a bluetooth speaker, the second device is a smart phone, the smart phone transmits audio data to the bluetooth speaker through bluetooth, and the bluetooth speaker plays the received audio data. The preset parameter value is an RSSI value, and the preset threshold value is-70 dBm. The preset threshold value is obtained through pre-training, when the RSSI value of the Bluetooth sound box relative to the smart phone is smaller than the preset threshold value, the audio signal received by the Bluetooth sound box is unstable, and the audio signal is played intermittently to influence the listening experience of a user. In the process, the Bluetooth sound box monitors the RSSI value relative to the smart phone in real time, and the RSSI value can change along with the change of the distance between the Bluetooth sound box and the smart phone. And when the Bluetooth sound box monitors that the RSSI value relative to the smart phone is always larger than or equal to-70 dBm, the Bluetooth sound box keeps Bluetooth connection with the smart phone. When the Bluetooth sound box monitors that the RSSI value relative to the smart phone is smaller than-70 dBm, the Bluetooth sound box actively breaks the Bluetooth connection with the smart phone, the Bluetooth sound box does not receive audio data any more at the moment, and meanwhile, the Bluetooth sound box outputs prompt information which can prompt a user of the reason that the Bluetooth connection cannot be established currently. For example, the bluetooth speaker outputs a prompt message "the current distance is too far, the bluetooth connection is disconnected", and after knowing the prompt message, the user can appropriately adjust the distance between the smart phone and the bluetooth speaker so as to increase the RSSI value of the bluetooth speaker relative to the smart phone to be greater than or equal to-70 dBm, thereby reestablishing the bluetooth connection.
According to the specific embodiment, the Bluetooth connection state between the Bluetooth sound box and the smart phone can be automatically controlled according to the RSSI value of the smart phone relative to the Bluetooth sound box, the condition that the quality of audio signals output by the Bluetooth sound box is poor is avoided, and the experience degree of a user is improved.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods.
Fig. 5 is a block diagram illustrating an apparatus for connecting devices, which may be implemented as part or all of an electronic device through software, hardware, or a combination of both, according to an example embodiment. Referring to fig. 5, the device connecting apparatus is applied to a first device, and includes an acquisition module 51 and a control module 52; wherein:
the obtaining module 51 is configured to obtain a preset parameter value with respect to the second device, the preset parameter value including at least one of a received signal strength indication value and a distance.
The control module 52 is configured to control a bluetooth connection state with the second device according to the preset parameter value acquired by the acquisition module 51.
By adopting the apparatus provided by the embodiment of the present disclosure, the control module 52 can control the bluetooth connection state between the first device and the second device according to the preset parameter value between the first device and the second device, so that the first device can automatically control the bluetooth connection state between the first device and the second device according to the received signal strength indication value or distance, thereby making the signal transmitted between the devices through bluetooth more optimal, and improving the user experience.
In one embodiment, as shown in FIG. 6, the control module 52 includes a first determination submodule 521, a first disconnection submodule 522, and a first establishment submodule 523; wherein:
the first determining sub-module 521 is configured to determine whether the received signal strength indicator value with respect to the second device is less than a preset threshold value when the preset parameter value includes the received signal strength indicator value.
The first disconnection submodule 522 is configured to disconnect the bluetooth connection with the second device when the first determination submodule 521 determines that the received signal strength indication value with respect to the second device is smaller than a preset threshold value.
The first establishing submodule 523 is configured to establish a bluetooth connection with the second device when the first determining submodule 521 determines that the received signal strength indicator value with respect to the second device is greater than or equal to a preset threshold value.
Among them, the RSSI (Received Signal Strength Indication) value is the indicated value of the Received Signal Strength. The larger the received signal strength indicating value is, the stronger the signal strength of the first device receiving the second device is, otherwise, the smaller the received signal strength indicating value is, the weaker the signal strength of the first device receiving the second device is, at this time, if the first device is still connected to the second device, the received signal is likely to be unstable, which affects the user experience.
For example, the preset threshold is set to-80 dBm, and the RSSI value of the first device relative to the second device may be changed by the interference of the external environment, for example, when the distance is changed, the RSSI value is also changed accordingly. The obtaining module 51 may monitor the RSSI value corresponding to the second device at any time, and assuming that the monitored RSSI value is-100 dBm, since the RSSI value is smaller than the preset threshold value-80 dBm, the first disconnection submodule 522 disconnects the bluetooth connection with the second device. Similarly, assuming that the monitored RSSI value is-70 dBm, the first establishing sub-module 523 establishes a bluetooth connection with the second device since the RSSI value is greater than the preset threshold of-80 dBm.
In addition, in the implementation, in order to enhance the signal of the second device received by the first device, a signal constant may be added based on a predetermined threshold, so as to raise a threshold for establishing the bluetooth connection between the first device and the second device. The signal constant may also be measured according to an actual scene, for example, on the premise that the first device and the second device are separated by a certain distance and no obstacle exists between the first device and the second device, the signal strength value of the second device received by the first device through bluetooth at this time is determined as the signal constant.
For example, if the predetermined threshold is-90 dBm and the set signal constant is-20 dBm, the control module 52 controls the bluetooth connection state with the second device, and the reference value is-90 dBm-20dBm, i.e., -70 dBm.
In this embodiment, the first disconnection submodule 522 may disconnect the second device when the received signal strength indicating value is smaller than the preset threshold, and the first establishment submodule 523 may establish connection when the received signal strength indicating value is greater than or equal to the preset threshold, so that the first device may automatically control the bluetooth connection state with the second device according to the received signal strength indicating value, so as to make the signals transmitted through bluetooth between the devices better, and avoid the situation that the received signals are not smooth when the signal strength is poor.
In one embodiment, as shown in FIG. 7, the control module 52 includes a second decision submodule 523, a second disconnection submodule 524, and a second setup submodule 525; wherein:

The second disconnection submodule 524 is configured to disconnect the bluetooth connection with the second device when the second judgment submodule 523 judges that the distance with respect to the second device is equal to or greater than the preset distance.
The second establishing submodule 525 is configured to establish a bluetooth connection with the second device when the second judging submodule 523 judges that the distance with respect to the second device is smaller than the preset distance.
In this embodiment, the smaller the distance between the first device and the second device is, the stronger the signal strength of the second device is received by the first device, whereas the larger the distance between the first device and the second device is, the weaker the signal strength of the second device is received by the first device is, at this time, if the first device is still connected to the second device, the received signal is likely to be unstable, which affects the experience of the user.
For example, the preset distance is set to 5m, and the obtaining module 51 may monitor the distance with respect to the second device at any time, and assuming that the monitored distance is 10m, since the distance value is greater than the preset distance of 5m, the second disconnection submodule 524 disconnects the bluetooth connection with the second device. Similarly, assuming that the monitored distance is 4m, the second establishing sub-module 525 establishes a bluetooth connection with the second device since the distance is less than the preset distance of 5 m.
In this embodiment, the preset distance may be determined in advance according to the fluency of the signal received by the first device from the second device at different locations, in a similar manner to the above-mentioned determination of the preset threshold: first, a threshold distance from the second device is determined, which is just a distance that allows the first device to smoothly receive the signal of the second device.
In this embodiment, the second disconnection sub-module 524 can disconnect when the distance to the second device is equal to or greater than the preset distance, and the second establishment sub-module 525 can establish connection when the distance to the second device is less than the preset distance, so that the first device can automatically control the bluetooth connection state with the second device according to the distance to the second device, thereby making signals transmitted through bluetooth between the devices better, and avoiding a situation that the received signals are not smooth when the distance is too far.

The critical position is a position where the signal received by the first device can be smoothed. The signals of the second device can be received at a plurality of different positions respectively, the fluency of the received signals at each position is recorded, and then the critical position is selected according to the fluency of the received signals at each position.
