In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The Internet of Things (IOT) is a network concept based on the "Internet concept" that extends and expands its client terminal to any item and item for information exchange and communication. With the development of IoT technology, some scenarios can be configured in the IoT system. For the configuration scenario, multiple electronic devices may be involved, and the multiple electronic devices have a certain linkage relationship and can work together. For example, the configured scenario may include that when one electronic device is close to another electronic device, at least one of the two electronic devices will perform a specified operation, for example, one of the electronic devices outputs connection prompt information, and the connection prompt information uses For prompting connection with another electronic device.

As shown in FIG. 1, the second electronic device 100 may be a user terminal (for example, may be a smart phone), and the first electronic device 200 may be a smart home device, which may include electronic devices such as smart TVs, air conditioners, and curtains. , when the second electronic device 100 is close to the first electronic device 200, the control interface of the first electronic device 200 is displayed on the second electronic device 100, and the user can control the first electronic device 200 through the second electronic device 100 The interface controls the first electronic device 200 to perform corresponding actions. Alternatively, the second electronic device 100 displays the connection prompt information of the first electronic device 200 , and the user can establish a connection between the second electronic device 100 and the first electronic device 200 through the connection prompt information displayed by the second electronic device 100 .

As shown in FIG. 2, the second electronic device 100 may be a user terminal (for example, may be a smart phone), and the first electronic device 200 may be a true wireless Bluetooth headset (true wireless stereo, TWS) device. In the first electronic device 200 When approaching the second electronic device 100, the second electronic device 100 displays pop-up information 110, in which the power of the TWS Bluetooth headset can be displayed, and connection prompt information can be displayed. In an embodiment of the present application, The TWS Bluetooth earphone device may include an earphone 220 and an earphone box (charging device) 210. The earphone box 210 can accommodate the earphone 220. In an embodiment of the application, the inner wall of the earphone box 210 forms an accommodating cavity, and the earphone 220 can be accommodated in Inside the accommodating chamber of the earphone box 210 . In addition, the earphone box 210 can not only provide a cavity for accommodating the earphone 220, but also can communicate with the earphone 220, so as to obtain information such as the power and name of the earphone 220, or the network parameters of the earphone 220, so that the user terminal can pass through the earphone box 210. The pairing with the earphone 220 is successful and the communication connection is realized. As an implementation manner, the earphone box 210 is also used for charging the earphone 220 . In an embodiment of the present application, when the earphone box 210 is opened, the earphone 220 can be triggered to transmit a Bluetooth low energy (bluetooh low energy, BLE) broadcast, and the second electronic device 100, such as a smart phone, after receiving the BLE broadcast , a pop-up box can pop up, and the pop-up box can provide the user with an operation interface for quickly connecting the earphone 220, or can simultaneously display the power of the earphone 220 and the power of the earphone box 210 in the pop-up box information.

At present, the distance between two electronic devices can be determined by the received signal strength of another electronic device received by one electronic device. In an embodiment of the present application, the ranging formula is as follows:

In formula (1), d represents the distance between two electronic devices, RSSI represents the received signal strength of another electronic device received by one electronic device, A is a reference distance, usually a constant, and B is a path loss factor. It can be seen from the formula (1) that there is a one-to-one correspondence between the distance d and the RSSI. Therefore, it is usually judged whether the distance between one electronic device and another electronic device is less than a preset distance, or whether an electronic device enters the preset range of another electronic device, usually by obtaining another electronic device received by one electronic device. The received signal strength of the device, and then, by judging whether the received signal strength is greater than the signal strength threshold, it is judged whether one electronic device enters the preset range of another electronic device.

In an embodiment of the present application, assuming that the two electronic devices are the second electronic device 100 and the first electronic device 200 respectively, when the first electronic device 200 activates the wireless communication module, the first electronic device 200 transmits a broadcast message to the surrounding . As shown in FIG. 3 , assuming that the second electronic device 100 is a user terminal, and the first electronic device 200 is a TWS Bluetooth earphone device, when the first electronic device 200 is close to the second electronic device 100, the cover of the earphone box 210 is closed state, then at this time, the earphone box 210 will not transmit broadcast messages to the surroundings, that is, as shown in FIG. The box cover of the second electronic device 100 is in an open state. As shown in FIG. 4 , the earphone 220 transmits a broadcast message, which can be received by the second electronic device 100, and the received signal strength of the received broadcast message is greater than the signal strength. When the threshold is reached, pop-up message 110 is displayed. By setting the signal strength threshold, it is possible to control the second electronic device 100 and the first electronic device 200 to trigger the pop-up window only within a certain distance, so as to avoid falsely triggering the pop-up window on other people's mobile phones to a certain extent.

In some embodiments, the wireless communication module can be a Wi-Fi module or a Bluetooth module. In the embodiment of the present application, the wireless communication module can be a Bluetooth module. The second electronic device 100 and the first electronic device 200 If they can be connected via Bluetooth, the broadcast message can be a Bluetooth broadcast message, for example, a BLE broadcast. As the distance between the first electronic device 200 and the second electronic device 100 approaches, the second electronic device 100 can detect the broadcast message of the first electronic device 200, and then can determine the broadcast message received by the first electronic device 200 The signal strength of the message, that is, the received signal strength. As the distance between the second electronic device 100 and the first electronic device 200 approaches, the received signal strength of the second electronic device 100 gradually increases. When the detected received signal strength When the signal strength is greater than the threshold, the second electronic device 100 displays pop-up information, and then the first electronic device 00 and the first electronic device 200 can establish a wireless connection (for example, a Bluetooth connection).

For example, a connection button is displayed in the bullet box information 110 displayed by the second electronic device 100, such as the connection control 111 shown in FIG. connection between.

Electronic devices can support the function of quickly discovering other electronic devices and displaying prompts. The judgment of whether to display prompt information by electronic devices is mainly based on the received signal strength of broadcast messages transmitted by other electronic devices and the set signal strength threshold. for a direct comparison. That is to say, other electronic devices will directly transmit the broadcast message according to the preset transmission power, and will not perform different processing for different scenarios, so that the prompt information of the electronic device that receives the broadcast message will be displayed incorrectly, resulting in Disturb the user and affect the user experience.

In view of the above problems, the inventor found after a long period of research, and proposed the transmission method, device, electronic equipment and storage medium of the broadcast message provided by the embodiment of the present application, by dynamically determining the target transmission power according to the state of the electronic equipment. The transmission of the broadcast message is used for other electronic devices to determine the display of the prompt information, so as to better control the display of the prompt information, avoid disturbing the user and improve the user experience. Wherein, the method for transmitting the broadcast message will be described in detail in the following embodiments.

Referring to FIG. 5 , FIG. 5 shows a schematic flowchart of a method for transmitting a broadcast message according to an embodiment of the present application. The method is used to dynamically determine the target transmission power according to the state of the electronic device to transmit the broadcast message, so that other electronic devices can determine the display of the prompt information, so as to better control the display of the prompt information and avoid the inconvenience to the user. Disturb to improve user experience. In a specific embodiment, the broadcast message transmitting method is applied to the broadcast message transmitting device 300 shown in Figure 12 and the electronic device (first electronic device) 500 configured with the broadcast message transmitting device 300 (Figure 14) . It can be understood that the first electronic device applied in this embodiment may be a smart phone, a tablet computer, a wearable electronic device, a bluetooth earphone, etc., which is not limited here. The process shown in Figure 5 will be described in detail below, and the method for transmitting a broadcast message may specifically include the following steps:

Step S110: According to the state of the first electronic device, determine a target transmission power from at least two preset transmission powers, wherein the at least two preset transmission powers are different in magnitude.

In this embodiment, the first electronic device can acquire its current state. Wherein, the state of the first electronic device may include a pairing state and a reconnection state.

In some implementation manners, the first electronic device may acquire its current state before the broadcast message is about to be transmitted. Wherein, the first electronic device is a TWS Bluetooth earphone and the second electronic device is a smart phone as an example for illustration. When the earphone box (charging device) accommodated by the TWS Bluetooth headset is turned on, the TWS Bluetooth headset can automatically turn on and try to transmit a broadcast message to try to establish a Bluetooth connection with the smartphone, then the TWS Bluetooth headset can obtain its the state you are in. When the headphone box of the TWS Bluetooth headset is closed, the TWS Bluetooth headset can automatically turn off and stop transmitting broadcast messages, and at this time, the TWS Bluetooth headset may not obtain its state.

In some implementation manners, the first electronic device may acquire the status of the first electronic device in response to the instruction information. For example, the first electronic device may acquire the state of the first electronic device in response to the target touch operation when detecting the target touch operation performed by the user on the first electronic device. For another example, when receiving the target voice information input by the user, the first electronic device may acquire the state of the first electronic device in response to the target voice information. For another example, when the first electronic device detects the preset time, it may acquire the status of the first electronic device in response to the preset time. For another example, when the first electronic device detects a preset environmental state (preset temperature, preset humidity, preset light intensity, preset brightness, etc.), Zhu Hangtian acquires the first electronic device in response to the preset environment. the state you are in.

As an implementable manner, the first electronic device may determine the state of the first electronic device based on its connection record. Wherein, when the first electronic device has a connection record, it can be determined that the state of the first electronic device is the reconnection state after pairing. When there is no connection record for the first electronic device, it may be determined that the state of the first electronic device is a pairing state.

As yet another implementable manner, the first electronic device may determine the state of the first electronic device based on its storage record. Wherein, when the first electronic device stores address information of other electronic devices, it can be determined that the state of the first electronic device is the reconnection state after pairing. When the first electronic device does not store address information of other electronic devices, it may be determined that the state of the first electronic device is a pairing state.

Of course, in this embodiment, the state of the first electronic device can also be obtained through other more ways, which will not be repeated here.

In some implementation manners, the first electronic device may preset and store at least two preset transmit powers with different magnitudes. For example, the first electronic device may preset and store a first preset transmit power and a second preset transmit power, and the first preset transmit power and the second preset transmit power are different in magnitude. For another example, the first electronic device may be preset and stored with the first preset transmit power, the second preset transmit power, the third preset transmit power...the Nth preset transmit power, and the first preset transmit power, The second preset transmit power, the third preset transmit power...the Nth preset transmit power have different sizes.

In this embodiment, after the first electronic device obtains its state, it can determine a preset transmission power from at least two preset transmission powers according to the state of the first electronic device as the target transmission power. power.

As an implementable manner, the first electronic device may pre-establish and store a mapping table, which may include at least two states, at least two preset transmission powers, at least two states, and at least two Correspondence between preset transmit powers, where each state in at least two states may correspond to one or more preset transmit powers, is not limited here. Please refer to Table 1, at least two states in the mapping table may include a first state, a second state, and a third state, and at least two preset transmit powers in the mapping table may include a first preset transmit power . The second preset transmit power and the third preset transmit power, wherein there is a corresponding relationship between the first state and the first preset transmit power, a corresponding relationship between the second state and the second preset transmit power, and a corresponding relationship between the third state and the first preset transmit power. There is a corresponding relationship among the three preset transmission powers.

Table 1

状态state	预设发射功率Default transmit power
第一状态first state	第一预设发射功率The first preset transmit power
第二状态second state	第二预设发射功率The second preset transmit power
第三状态third state	第三预设发射功率The third preset transmit power
……...	……...

Based on the above mapping table, when it is determined that the state of the first electronic device is the first state, the first preset transmission power can be determined as the target transmission power; when it is determined that the state of the first electronic device is the second state, the second preset transmit power can be determined as the target transmit power; when the state of the first electronic device is determined to be the third state, the third preset transmit power can be determined as the target transmit power, and so on.

In some implementations, the first electronic device may preset and store a fixed amount of preset transmit power as the default preset transmit power, and correspond the default preset transmit power to one of the states of the electronic device . In specific implementation, when the obtained state of the first electronic device is consistent with one of the states, the default preset transmit power can be used as the target transmit power; when the state of the first electronic device is obtained If it is inconsistent with one of the states, a certain value may be increased or decreased on the basis of the default preset transmit power to obtain a new preset transmit power as the target transmit power.

In this embodiment, the preset transmit power may be Bluetooth low energy transmit power.

Step S120: Transmitting a broadcast message based on the target transmission power to instruct the second electronic device that has received the broadcast message to display target information when the received signal strength of the broadcast message is determined to be greater than a received signal strength threshold.

In this embodiment, after determining the target transmission power, the first electronic device may transmit the broadcast message based on the target transmission power. It can be understood that the larger the target transmit power, the wider (farther) the coverage of the broadcast message transmitted based on the target transmit power, and the greater the received signal strength of the broadcast message received at the same location; If is smaller, the coverage of the broadcast message transmitted based on the target transmit power is narrower (closer), and the received signal strength of the broadcast message received at the same location is smaller. For example, assuming that the preset transmit power includes a first preset transmit power and a second preset transmit power, and the first preset transmit power is greater than the second preset transmit power, then, when the first preset transmit power is determined as the target transmit power, the coverage of the broadcast message transmitted based on the target transmit power can be S1, and the received signal strength of the broadcast message received at the same location is RSSI1, when the second preset transmit power is determined as the target transmit power, then The coverage of the broadcast message transmitted based on the target transmission power may be S2, and the received signal strength of the broadcast message received at the same location is RSSI2, then the coverage of S1 is greater than the coverage of S2, and RSSI1 is greater than RSSI2.

Wherein, when the second electronic device is within the broadcast coverage of the first electronic device, the second electronic device may receive the broadcast message transmitted by the first electronic device. Correspondingly, when the second electronic device receives the broadcast message transmitted by the first electronic device, it may obtain the received signal strength of the received broadcast message, and compare the received signal strength with a preset received signal strength threshold. Wherein, when the size comparison result indicates that the received signal strength is greater than the preset received signal strength threshold, the target information may be displayed on the second electronic device; when the size comparison result indicates that the received signal strength is not greater than the preset received signal strength threshold , the target information is not displayed on the second electronic device.

In some implementation manners, the second electronic device may calculate the received signal strength of the broadcast message according to the received broadcast message transmitted by the first electronic device. In one calculation method, received signal strength = RxPower-SystemGain, wherein, RxPower is to perform analog/digital conversion on the received wireless signal, and then perform digital front end (digital front end, DFE) filtering and other processing, and then calculate and obtain The in-band received power of the signal; SystemGain indicates the system gain, which can be estimated according to the RF front-end.

In some embodiments, the first electronic device is a TWS Bluetooth earphone device, and the second electronic device is a smart phone as an example for illustration. When the earphone box (charging device) accommodated by the earphone is opened, the earphone can automatically turn on and try to transmit broadcast messages with the determined target transmission power in order to try to establish a Bluetooth connection with the smartphone. When the earphone of the TWS Bluetooth earphone device When the lid is closed, the headset may automatically switch off and stop transmitting broadcast messages at the determined target transmit power. Correspondingly, when the smart phone is within the broadcasting range of the earphone, it can receive the broadcast message transmitted by the earphone at the determined target transmit power, and obtain the information of the received broadcast message transmitted by the earphone at the determined target transmit power. Received signal strength.

It can be understood that when the first electronic device transmits a broadcast message, if the number of second electronic devices within the broadcast coverage of the first electronic device is one, only the second electronic device can receive the first electronic device. A broadcast message transmitted by an electronic device, and obtain the received signal strength of the broadcast message; if there are multiple second electronic devices within the broadcast coverage of the first electronic device, all of the multiple second electronic devices The broadcast message transmitted by the first device can be received, and the received signal strength of the broadcast message can be obtained.

In some embodiments, after obtaining the received signal strength of the broadcast message transmitted by the first electronic device, the second electronic device may compare the received signal strength with a received signal strength threshold to determine whether the received signal strength is greater than Received signal strength threshold. Wherein, when it is determined that the received signal strength is not greater than the received signal strength threshold, it can be determined that the received signal strength does not meet the signal strength requirement for displaying prompts, then the target information can be intercepted, that is, the target information can not be displayed. Wherein, when it is determined that the received signal strength is greater than the received signal strength threshold, it can be determined that the received signal strength meets the signal strength requirement for displaying prompts, and then the target information is displayed, that is, the target information can be displayed.

In some implementations, the way the second electronic device displays the target information may include: displaying the target information on a display interface, displaying the target information in a pop-up window on the display interface, displaying the target information in a status bar, etc., which is not limited here.

In some embodiments, the state of the second electronic device may include a pairing state and a reconnecting state. Wherein, when the state of the second electronic device is the configuration state, the target information may be connection prompt information, that is, the target information may be used to prompt to perform a pairing and connection operation with the second electronic device. Wherein, when the state of the second electronic device is the connection back state, the target information may be connection success prompt information, that is, the target information may be used to prompt that the connection back with the second electronic device has been successfully performed.

According to the broadcast message transmission method provided by an embodiment of the present application, according to the state of the first electronic device, the target transmission power is determined from at least two preset transmission powers with different sizes, and the broadcast message is transmitted based on the target transmission power to indicate The second electronic device that receives the broadcast message displays the target information when it determines that the received signal strength of the broadcast message is greater than the received signal strength threshold, so as to transmit the broadcast message by dynamically determining the target transmission power according to the state of the electronic device, It is used for other electronic devices to determine the display of the prompt information, so as to better control the display of the prompt information, avoid disturbing the user and improve the user experience.

Referring to FIG. 6 , FIG. 6 shows a schematic flowchart of a method for transmitting a broadcast message according to an embodiment of the present application. The method is applied to the above-mentioned first electronic device, and the following will elaborate on the process shown in FIG. 6 . In this embodiment, the at least two preset transmit powers include the first preset transmit power and the second preset Transmission power, wherein the first preset transmission power is greater than the second preset transmission power, and the method for transmitting a broadcast message may specifically include the following steps:

Step S210: When the state of the first electronic device is a pairing state, determine a first preset transmission power from the at least two preset transmission powers as the target transmission power, wherein the pairing state It is used to represent the pairing operation to be performed between the first electronic device and the second electronic device.

In this embodiment, the at least two preset transmit powers include a first preset transmit power and a second preset transmit power, wherein the first preset transmit power is greater than the second preset transmit power. As a method, the first preset transmit power can be the default value of the pre-test, then the second preset transmit power can be obtained by subtracting a certain value from the first preset transmit power, as another In this way, the second preset transmit power may be a default value after pre-testing, and then the first preset transmit power may be obtained by adding a certain value to the second preset transmit power.

As a manner, the state of the first electronic device may include a pairing state. Wherein, the first electronic device is in the pairing state, which means that other electronic devices within the broadcast coverage of the first electronic device can scan the first electronic device at any time, and can pair and connect with the first electronic device. In this embodiment, the pairing status can be used to represent the pending pairing operation between the first electronic device and the second electronic device. As an implementable manner, the second electronic device may be any electronic device that can scan to the first electronic device and has not been paired with the first electronic device.

In some implementations, when it is determined that the state of the second electronic device is the pairing state, it can be considered that the first electronic device is not targeted to transmit broadcast messages at this time, and the second electronic device can be made to The target information is displayed to prompt the user corresponding to the second electronic device to establish a connection with the first electronic device. Based on this, in this embodiment, a larger preset transmit power can be selected from the first preset transmit power and the second preset transmit power as the target preset transmit power, so that the second electronic device receives The received signal strength of the broadcast message of the first electronic device is more likely to be greater than the preset received signal strength threshold, thereby increasing the probability of displaying the target information. In an embodiment of the present application, when it is determined that the state of the first electronic device is the pairing state, the first preset transmission power can be determined as the target from the first preset transmission power and the second preset transmission power Preset transmit power.

Step S220: When the state of the first electronic device is the connection back state, determine the second preset transmit power from the at least two preset transmit powers as the target transmit power, wherein the The connection back status is used to represent the connection back operation between the first electronic device and the third electronic device after pairing is to be performed.

As a manner, the state of the first electronic device may include a reconnection state after pairing. Wherein, the first electronic device is in the connection back state, which means that the first electronic device is performing a connection back operation with the previously paired and connected electronic device through paging. In this embodiment, the connection back status can be used to represent the connection back operation after the first electronic device and the third electronic device are to be paired, wherein the third electronic device can be a pairing connection on the first electronic device old electronic equipment.

In some implementations, when it is determined that the state of the first electronic device is the connection back state, it can be considered that the first electronic device is more likely to be connected to an electronic device that has been paired and connected before. If the electronic device is connecting back to the third electronic device that has been paired and connected before, the second electronic device may not display the target information as much as possible to reduce disturbance to the user corresponding to the second electronic device. Based on this, in this embodiment, a smaller preset transmit power can be selected as the target transmit power from the first preset transmit power and the second preset transmit power, so that the first preset transmit power received by the second electronic device The received signal strength of the broadcast message of the electronic device is more likely to be smaller than the preset received signal strength threshold, thereby reducing the probability of displaying the target information. In an embodiment of the present application, when it is determined that the state of the first electronic device is the connection back state, the second preset transmit power may be determined from the first preset transmit power and the second preset transmit power as Target preset transmit power.

Step S230: Transmitting a broadcast message based on the target transmission power to instruct the second electronic device that has received the broadcast message to display target information when it is determined that the received signal strength of the broadcast message is greater than a received signal strength threshold.

Wherein, for the specific description of step S230, please refer to step S120, which will not be repeated here.

The broadcast message transmission method provided by an embodiment of the present application obtains the state of the first electronic device, and when the state of the first electronic device is the configuration state, determines the first transmission from at least two preset transmission powers.
