[0029] The embodiments of this application are described in detail below. These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] Please see Figures 1-3 The notification method described in this application is used for a target device 100. The target device 100 is capable of wirelessly connecting to an electronic device 200. The notification method includes:

[0032] 011: When the target device 100 is inside the housing, a signal is transmitted to the electronic device 200 at a first transmission power;

[0033] 013: When the target device 100 is outside the containment, a signal is transmitted to the electronic device 200 at a second transmission power. The signal is used to trigger the electronic device 200 to determine whether to prompt the target device 100 with preset information based on the signal strength of the received signal after receiving the signal.

[0034] The notification method of this application embodiment can be implemented by the target device 100 of this application embodiment. Specifically, the target device 100 includes a first processor 10. The first processor 10 is used to transmit a signal to the electronic device 200 at a first transmission power when the target device 100 is located inside the housing, and to transmit a signal to the electronic device 200 at a second transmission power when the target device 100 is located outside the housing. The signal is used to trigger the electronic device 200 to determine whether to notify the target device 100 of preset information based on the signal strength of the received signal after receiving the signal.

[0035] The prompting method of this application embodiment can be implemented by the prompting device 12 of this application embodiment. Specifically, the prompting device 12 includes a first transmitting module 122 and a second transmitting module 124. The first transmitting module 122 is used to transmit a signal to the electronic device 200 at a first transmitting power when the target device 100 is located inside the housing. The second transmitting module 124 is used to transmit a signal to the electronic device 200 at a second transmitting power when the target device 100 is located outside the housing. The signal is used to trigger the electronic device 200 to determine whether to prompt the target device 100 with preset information based on the signal strength of the received signal after receiving the signal. For example, the prompting device 12 can be a Bluetooth transmitting device.

[0036] The aforementioned prompting method, target device 100, and prompting device 12 dynamically adjust the transmission power of the target device 100, taking into account changes in the state of the target device 100 and the housing, thereby better controlling the prompting distance and avoiding confusion for users regarding frequent or no prompts. This enhances the user experience and improves the user's quality of life.

[0037] Understandably, the signal strength of the received signal can be characterized by the Received Signal Strength Indicator (RSSI). Determining whether to prompt the target device 100 with preset information based on the signal strength of the received signal can be achieved by directly comparing the received signal strength with the target signal strength. If the signal strength is greater than or equal to the target signal strength, the distance between the two is considered to be within the prompting range; if the signal strength is less than the target signal strength, the distance between the two is considered to be beyond the prompting range. The target signal strength is related to the prompting distance desired by the target device. Alternatively, the received signal strength can be converted into a distance, and then the converted distance can be compared with the prompting distance to determine whether to prompt. All these methods are within the protection scope of this application. It is understandable that in related technologies, regardless of whether the target device is inside or outside the containment, it always transmits a signal to the electronic device at a fixed power. The inventors have discovered that when the target signal strength used by the electronic device to determine whether to display preset information to the target device is already determined, the following two problems arise: First, after defining a suitable transmission power based on the target device being inside the containment, it is possible that when the target device is outside the containment and transmits a signal to the electronic device at that power, other electronic devices located far from the target device may receive a signal strength greater than the target signal strength, resulting in preset information prompts appearing on other electronic devices and disturbing users of those devices. Second, after defining a suitable transmission power based on the target device being outside the containment, it is possible that when the target device is inside the containment and transmits a signal to the electronic device at that power, and the user wants to be prompted with preset information, the electronic device may not display the preset information because the received signal strength cannot exceed the target signal strength, thus affecting the user experience. Further research revealed that some housing components, such as headphone charging cases, can influence the signal transmitted by the headphones within the case due to their design. This influence can be positive, benefiting signal transmission, or negative, interfering with it. The target signal strength refers to the signal strength of the signal transmitted by the target device received by the electronic device at a specified distance. It can be understood that when the signal strength of the signal transmitted by the target device received by the electronic device reaches the target signal strength, the distance between the target device and the electronic device can be determined to be equal to the specified distance. The specified distance is the distance at which the electronic device is expected to display a preset message to the target device. When the distance between the target device and the electronic device is determined to be less than or equal to the specified distance, the electronic device can display the preset message to the target device.

[0038] The notification method of this application takes into account the changes in the state of the target device 100 and the housing. When the target device 100 is outside the housing, a signal is transmitted to the electronic device 200 with a second transmission power. When the target device 100 is inside the housing, a signal is transmitted to the electronic device 200 with a first transmission power. This prevents the signal strength received by the electronic device 200 from deviating from the predetermined signal strength due to the housing obstructing the signal transmitted by the target device 100, thereby affecting the preset information of the target device 100. It is understandable that, taking the obstruction of headphone signals by the housing as an example, housings of different sizes and materials have different obstructive effects on signals. When determining the target signal strength used to determine whether to prompt the target device 100 with preset information, if the obstruction of the housing on the signal is not considered, then in actual use, when the target device 100 is located inside the housing, even if the distance between the target device 100 and the electronic device 200 is less than the distance corresponding to the target signal strength, that is, the signal strength of the signal received by the electronic device 200 should be greater than the target signal strength, and the electronic device 200 should prompt the target device 100 with preset information, due to the obstruction of the housing on the signal, the signal strength of the signal actually received by the electronic device 200 is less than the target signal strength, and therefore the electronic device 200 does not prompt the target device 100 with preset information, resulting in the problem of not prompting preset information. Therefore, considering the obstruction of the housing to the signal, when the target device 100 is inside the housing, the target device 100 transmits the signal at a higher power than when the target device 100 is outside the housing. This ensures that when the distance between the target device 100 and the electronic device 200 is less than the distance corresponding to the target signal strength, the signal strength of the signal received by the electronic device 200 can be greater than the target signal strength as expected, thereby prompting the target device 100 with preset information.

[0039] Specifically, the target device 100 can be understood as a device that supports the electronic device 200 in displaying preset information. For example, the target device 100 may include wireless headphones (including Bluetooth headphones), Bluetooth speakers, smart home appliances, etc., that support the electronic device 200 in displaying quick pop-up prompts. The electronic device 200 may include mobile phones, tablets, laptops, personal computers, wearable smart devices, smart home appliances, etc. The electronic device 200 may display preset information to the target device 100 by playing voice prompts or displaying pop-up prompts. The target device 100 may wirelessly connect to the electronic device 200 via Bluetooth, infrared, or other means. The housing can be used to house the target device 100. In some embodiments, when the target device 100 is housed within the housing, the housing can protect the target device 100 to achieve waterproofing, dustproofing, impact resistance, and portability. In some embodiments, when the target device 100 is housed within the housing, the housing can provide power to the target device 100. For example, if the electronic device 200 is a TWS (True Wireless Stereo) headset, the housing is a headset charging case.

[0040] In some implementations, the first transmission power is greater than the second transmission power. For example, the preset information of the target device 100 may include identification information, battery level information, distance information, connection status information, etc. The identification information may include device ID, device model, device name, etc.

[0041] It should be noted that in some embodiments, when the distance between the target device 100 and the electronic device 200 is constant, regardless of whether the target device 100 is inside the housing and transmits a signal to the electronic device 200 with a first transmission power, or the target device 100 is outside the housing and transmits a signal to the electronic device 200 with a second transmission power, the signal strength received by the electronic device 200 is the same or approximately the same (e.g., controlled within a very small range). That is to say, the setting of the first transmission power and the second transmission power is just such that the signal strength received by the electronic device 200 at the same distance is the same or approximately the same whether the target device 100 is inside or outside the housing. Thus, regardless of whether the target device 100 is inside or outside the housing, the electronic device 200 can provide a prompt or not as expected at the same distance, which can ensure the consistency of the pop-up window situation inside and outside the housing to a certain extent.

[0042] It should be noted that, in some embodiments, the target device 100 may transmit signals to the electronic device 200 only when the target device 100 is in discoverable mode. In some embodiments, the signal transmitted by the target device 100 is a Bluetooth broadcast signal. Specifically, the Bluetooth broadcast signal can be in the form of Bluetooth Low Energy (BLE) broadcast or classic Bluetooth. The trigger condition for discoverable mode can be the first use after leaving the factory (e.g., the first time the case is opened), or it can be triggered by receiving a user-triggered instruction to open discoverable mode (e.g., pressing a button). For example, in discoverable mode, the transmitted Bluetooth broadcast signal (such as a BLE broadcast signal) can be used to trigger a pairing prompt pop-up window based on the signal strength of the received signal after the electronic device 200 receives the broadcast signal. The user can then establish a quick pairing connection with the headset based on this pairing prompt pop-up window. In some embodiments, the target device 100 can connect to two or more electronic devices 200 simultaneously.

[0043] In one example, electronic device 200 is a mobile phone, target device 100 is a True Wireless Stereo (TWS) Bluetooth headset, and the housing is a charging case. The mobile phone and TWS Bluetooth headset can connect wirelessly via Bluetooth, and data can be transmitted between them. The left and right earbuds of the TWS Bluetooth headset are independent and do not require a cable connection, achieving wireless separation of the left and right channels. The TWS Bluetooth headset can be housed in the charging case. When the TWS Bluetooth headset is housed in the charging case, the charging case both powers and protects the TWS Bluetooth headset. Understandably, the Bluetooth headset can be configured to send a BLE broadcast when the charging case is opened. This BLE broadcast signal can use a proprietary protocol, or it can be an industry-standard or open-source protocol supported by both target device 100 and electronic device 200. Thus, electronic device 200 can determine whether the sending device is target device 100 based on the signal condition. This BLE broadcast can be a connectable broadcast. Furthermore, it can be set to send a BLE broadcast when the charging case is first opened, or when it is not first opened, or even in other situations. The electronic device 200 can determine the form of the pop-up based on whether there is a pairing history. For example, if there is no pairing history with the target device 100, a pop-up window will pop up allowing the user to establish a Bluetooth connection with the target device 100. Or, if the electronic device 200 has a previous pairing history with the target device 100, since the target device 100 will directly initiate a reconnection with the electronic device 200, the electronic device 200 does not need to pop up a connectable pop-up like the one for the first pairing. Instead, the electronic device 200 can be set to pop up a connection success pop-up after the connection is established.

[0044] In one example, electronic device 200 is a mobile phone, target device 100 is a TWS Bluetooth headset, and the housing is a charging case. When the TWS Bluetooth headset is used for the first time, i.e., when the headset is housed in the housing and the housing is initially open, the headset is in discoverable mode, transmitting signals to the mobile phone, allowing it to connect. After establishing a connection with a mobile phone D1, the headset can be set to automatically deactivate discoverable mode, ceasing signal transmission to other mobile phones. During the continuous connection between the headset and mobile phone D1, upon receiving a command to reactivate discoverable mode, the headset reactivates and re-enters discoverable mode, again transmitting signals to other mobile phones, allowing them to connect. When the headset establishes a connection with another mobile phone D2, it can automatically deactivate discoverable mode again, ceasing signal transmission to other mobile phones, and this cycle repeats. Mobile phones D1 and D2 can be the same model or different models.

[0045] Furthermore, in some embodiments, the housing includes a body and a top cover. The target device 100 can be housed within a cavity of the body, and the top cover is used to cooperate with the body to allow the housing to be in an open or closed state. When the target device 100 is housed within a cavity of the body and the housing is in the closed state, it is determined that the target device 100 is located inside the housing, and the target device 100 does not transmit signals. When the target device 100 is housed within a cavity of the body and the housing is in the open state, it is determined that the target device 100 is located inside the housing, and the target device 100 can transmit signals to the electronic device 200. When the target device 100 is removed from a cavity of the body, it is determined that the target device 100 is located outside the housing, and the target device 100 can transmit signals to the electronic device 200.

[0046] Understandably, the target device 100 can determine whether the housing is in an open state based on electrical signals generated by devices such as light sensors, infrared sensors, or contact switches provided on the target device 100 and / or the housing. For example, an infrared receiver and an infrared transmitter are respectively provided on the body and top cover of the housing. When the housing is in a closed state, the infrared receiver can receive the infrared rays emitted by the infrared transmitter, thereby transmitting the relevant signal to the target device 100, and the target device 100 determines that the housing is in a closed state. When the housing is in an open state, the infrared receiver cannot receive the infrared rays emitted by the infrared transmitter, thereby transmitting the relevant signal to the target device 100, and the target device 100 determines that the housing is in an open state and transmits a signal. The target device 100 can also determine whether it is located inside the housing based on electrical signals generated by devices such as light sensors, infrared sensors, or contact switches. For example, the housing is provided with contacts, and the target device 100 is provided with contacts. When the contacts are in contact with the contacts, the target device 100 determines that it is located inside the housing; when the contacts are disconnected from the contacts, the target device 100 determines that it is located outside the housing. Taking a Bluetooth headset as the target device 100 and an earphone case as the housing as an example, after the Hall sensor or other opening detection device on the earphone case detects that the case is open, it can transmit opening information to the Bluetooth headset through contacts between the Bluetooth headset and the earphone case, such as a pogo pin, thereby triggering the Bluetooth headset to transmit BLE broadcast. The Bluetooth headset can determine whether it is inside the housing by detecting the voltage of the contacts, or it can determine whether the earphone has been taken out of the earphone case by setting a magnetic sensor or light sensor on the earphone stem. Of course, other methods of detecting whether the earphone is in or out of the case can also be used.

[0047] Please see Figure 4 and Figure 5 In some implementations, prior to step 011, the prompting method further includes:

[0048] 015: Determine the prompt distance and the target signal strength received by the electronic device 200 at the prompt distance;

[0049] 016: When the target device 100 is located inside the containment and the target device 100 and the electronic device 200 maintain a prompting distance, determine the first signal strength of the signal received by the electronic device 200;

[0050] 017: Determine the first transmission power based on the target signal strength and the first signal strength;

[0051] 018: When the target device 100 is outside the containment and the target device 100 and the electronic device 200 maintain a prompting distance, determine the second signal strength of the signal received by the electronic device 200;

[0052] 019: Determine the second transmit power based on the target signal strength and the second signal strength.

[0053] The prompting method described above can be implemented by the target device 100 of this application. Specifically, the first processor 10 is configured to determine the prompting distance and the target signal strength of the signal received by the electronic device 200 corresponding to the prompting distance, and to determine the first signal strength of the signal received by the electronic device 200 when the target device 100 is located inside the housing and the target device 100 and the electronic device 200 maintain the prompting distance, and to determine the first transmission power based on the target signal strength and the first signal strength, and to determine the second signal strength of the signal received by the electronic device 200 when the target device 100 is located outside the housing and the target device 100 and the electronic device 200 maintain the prompting distance, and to determine the second transmission power based on the target signal strength and the second signal strength.

[0054] The prompting method described above can be implemented by the prompting device 12 of this application. Specifically, the prompting device 12 includes a first determining module 125, a second determining module 126, a third determining module 127, a fourth determining module 128, and a fifth determining module 129. The first determining module 125 is used to determine the prompting distance and the target signal strength of the signal received by the electronic device 200 at the corresponding prompting distance. The second determining module 126 is used to determine the first signal strength of the signal received by the electronic device 200 when the target device 100 is located inside the housing and the target device 100 maintains the prompting distance with the electronic device 200. The third determining module 127 is used to determine the first transmission power based on the target signal strength and the first signal strength. The fourth determining module 128 is used to determine the second signal strength of the signal received by the electronic device 200 when the target device 100 is located outside the housing and the target device 100 maintains the prompting distance with the electronic device 200. The fifth determining module 129 is used to determine the second transmission power based on the target signal strength and the second signal strength. For example, the first and second transmission powers can be tested and set in the target device before leaving the factory. For instance, when the target device's housing is opened or its button is triggered, the housing can send a signal via a connector such as a Pogopin to notify the target device to turn on or wake up the wireless device (such as a Bluetooth chip). The target device can then detect its current location information (whether inside or outside the housing) in real time or periodically. When it detects that the target device is currently inside the housing, it transmits a signal at the first transmission power; when it detects that the target device is currently outside the housing, it transmits a signal at the second transmission power. Understandably, when the signal transmitted by the housing has a positive impact on the target device (i.e., the signal is transmitted from inside the housing), the housing design enhances the signal transmission capability. In this case, the first transmission power can be less than the second transmission power. When the signal transmitted by the housing has a negative impact on the target device (i.e., the signal is transmitted from inside the housing and the housing interferes with the signal transmission), the first transmission power can be set to be greater than the second transmission power. Understandably, the first and second transmission powers can be determined based on the degree of influence of the housing on signal transmission. Thus, by pre-calibrating the first and second transmission powers based on the prompt distance and the target signal strength, it is ensured that when the distance between the target device 100 and the electronic device 200 is the prompt distance, regardless of whether the target device 100 is inside the housing and transmits a signal to the electronic device 200 at the first transmission power or outside the housing and transmits a signal to the electronic device 200 at the second transmission power, the signal strength received by the electronic device 200 will be the target signal strength. This further ensures a certain degree of consistency between the pop-up window triggered by the headphone broadcast signal when the user has not removed the headphones and the pop-up window triggered by the headphone broadcast signal after the user has removed the headphones, thereby improving the user experience.

[0055] Specifically, the target signal strength refers to the signal strength of the signal transmitted by the target device 100 received by the electronic device 200 when the target device 100 and the electronic device 200 are at the indicated distance. It can be understood that when the signal strength of the signal transmitted by the target device 100 received by the electronic device 200 reaches the target signal strength, it can be determined that the distance between the target device 100 and the electronic device 200 is equal to the indicated distance. The indicated distance is the distance at which the electronic device 200 is expected to indicate preset information to the target device 100. When it is determined that the distance between the target device 100 and the electronic device 200 is less than or equal to the indicated distance, the electronic device 200 may indicate the preset information to the target device 100. For example, when the distance between the target device 100 and the electronic device 200 is greater than the indicated distance, the electronic device 200 is not expected to indicate the preset information to the target device 100; when the distance between the target device 100 and the electronic device 200 is less than or equal to the indicated distance, the electronic device 200 is expected to indicate the preset information to the target device 100. The indicated distance may include 20cm, 25cm, 30cm, 35cm, 40cm, etc. There is a correlation between the prompt distance and the target signal strength. By comparing the signal strength of the signal received by electronic device 200 with the target signal strength, it can be determined whether the distance between target device 100 and electronic device 200 meets the prompt distance requirement, and thus whether to prompt the target device 100 with preset information. For example, if the signal strength of the signal received by electronic device 200 is greater than or equal to the target signal strength, it is determined that the distance between target device 100 and electronic device 200 meets the prompt distance requirement, and electronic device 200 is controlled to prompt the target device 100 with preset information; if the signal strength of the signal received by electronic device 200 is less than the target signal strength, it is determined that the distance between target device 100 and electronic device 200 does not meet the prompt distance requirement, and electronic device 200 is not controlled to prompt the target device 100 with preset information.

[0056] Optionally, during the calibration of the first transmission power, the prompting distance and target signal strength are predetermined. The target device 100 and the electronic device 200 are kept at the prompting distance and the target device 100 is kept inside the housing. The target device 100 is controlled to transmit a signal at the preset transmission power. The first signal strength of the signal received by the electronic device 200 is recorded. The first signal strength and the target signal strength are compared. If the first signal strength is equal to the target signal strength, the preset transmission power is directly used as the first transmission power. If the first signal strength is not equal to the target signal strength, the transmission power of the target device 100 is increased or decreased until the first signal strength of the signal received by the electronic device 200 is equal to the target signal strength. The transmission power of the target device 100 when the first signal strength is equal to the target signal strength is then used as the first transmission power.

[0057] Similarly, during the calibration of the second transmission power, the prompting distance and target signal strength are predetermined. The target device 100 and electronic device 200 are kept at the same prompting distance and the target device 100 is kept outside the housing. The target device 100 is controlled to transmit a signal at the preset transmission power. The second signal strength of the signal received by the electronic device 200 is recorded. The second signal strength and the target signal strength are compared. If the second signal strength is equal to the target signal strength, the preset transmission power is directly used as the second transmission power. If the second signal strength is not equal to the target signal strength, the transmission power of the target device 100 is increased or decreased until the second signal strength of the signal received by the electronic device 200 is equal to the target signal strength. The transmission power of the target device 100 when the second signal strength is equal to the target signal strength is used as the second transmission power.

[0058] In some implementations, the signal includes identification information of the target device 100. Transmitting the signal to the electronic device 200 includes: transmitting a signal including identification information to the electronic device 200. The signal is used to trigger the electronic device 200 to determine whether to display the identification information of the target device 100 based on the signal strength after receiving the signal.

[0059] The prompting method described above can be implemented by the target device 100 of this application. Specifically, the first processor 10 is used to transmit a signal including identification information to the electronic device 200. The signal is used to trigger the electronic device 200 to determine whether to prompt the target device 100 with the identification information based on the signal strength after receiving the signal.

[0060] The prompting method described above can be implemented by the prompting device 12 of this application. Specifically, the transmitting module 122 is used to transmit a signal including identification information to the electronic device 200. The signal is used to trigger the electronic device 200 to determine whether to prompt the target device 100 with its identification information based on the signal strength after receiving the signal.

[0061] In this way, the electronic device 200 can prompt the user whether to connect to the target device 100 based on the identification information of the target device 100.

[0062] Specifically, the identification information may include device ID, device model, device name, etc. The electronic device 200 may prompt the target device 100 with the identification information via voice or pop-up window.

[0063] Please see Figures 6-8 The notification method described in this application is used in an electronic device 200. The electronic device 200 is capable of wirelessly connecting to a target device 100. The notification method includes:

[0064] 021: Receive signals transmitted by the target device 100, including signals transmitted to the electronic device 200 at a first transmission power when the target device 100 is inside the housing, or signals transmitted to the electronic device 200 at a second transmission power when the target device 100 is outside the housing;

[0065] 023: Determine whether to prompt the target device 100 with preset information based on the signal strength of the received signal.

[0066] The notification method of this application embodiment can be implemented by the electronic device 200 of this application embodiment. Specifically, the electronic device 200 includes a second processor 20. The second processor 20 is used to receive signals transmitted by the target device 100, including signals transmitted to the electronic device 200 at a first transmission power when the target device 100 is located inside the housing, or signals transmitted to the electronic device 200 at a second transmission power when the target device 100 is located outside the housing; and to determine whether to notify the target device 100 of preset information based on the signal strength of the received signal.

[0067] The prompting method of this application embodiment can be implemented by the prompting device 22 of this application embodiment. Specifically, the prompting device 22 includes a receiving module 222 and a determining module 224. The receiving module 222 is used to receive signals transmitted by the target device 100, including signals transmitted to the electronic device 200 at a first transmission power when the target device 100 is located inside the housing, or signals transmitted to the electronic device 200 at a second transmission power when the target device 100 is located outside the housing. The determining module 224 is used to determine whether to prompt the target device 100 with preset information based on the signal strength of the received signal.

[0068] The aforementioned prompting method, electronic device 200, and prompting device 22 dynamically adjust the transmission power of the target device 100 by taking into account the changes in the state of the target device 100 and the housing, thereby better controlling the prompting distance, avoiding confusion for users due to frequent or no prompts, improving user experience, and enhancing the user's quality of life.

[0069] Specifically, the electronic device 200 can prompt the target device 100 with preset information through voice broadcasts or pop-up windows. After receiving a signal transmitted by the target device 100, the electronic device 200 can determine the signal strength of the received signal and compare it with the target signal strength. If the received signal strength is greater than or equal to the target signal strength, it can determine that the distance between the target device 100 and the electronic device 200 meets the prompt distance, thus prompting the target device 100 with the preset information. If the received signal strength is less than the target signal strength, it can determine that the distance between the target device 100 and the electronic device 200 does not meet the prompt distance, thus not prompting the target device 100 with the preset information. The target signal strength can be stored on a cloud server. The electronic device 200 can wirelessly connect to the cloud via Wi-Fi or other means. When it is necessary to compare the signal strength of received signals, the electronic device 200 can directly obtain the target signal strength from the cloud server and compare it. The target signal strength can also be stored in the memory of the electronic device 200. When it is necessary to compare the signal strength of received signals, the electronic device 200 can directly retrieve the target signal strength from the local memory and compare it.

[0070] It should be noted that when the electronic device 200 prompts the target device 100 with the preset information, the electronic device 200 has not yet established a wireless connection with the target device 100. After prompting the target device 100 with the preset information, when the electronic device 200 receives the instruction to confirm the establishment of a wireless connection with the target device 100, the electronic device 200 establishes a wireless connection with the target device 100.

[0071] In some embodiments, the electronic device 200 includes a signal receiver for receiving signals transmitted by the target device 100. After receiving the signal transmitted by the target device 100, the signal receiver generates a corresponding electrical signal and transmits the electrical signal to a second processor 20. The second processor 20 can determine the signal strength of the received signal transmitted by the target device 100 based on the received electrical signal from the signal receiver and compare the magnitude of the signal strength with that of a target signal. In some embodiments, the electronic device 200 further includes a signal receiver for receiving signals transmitted by the target device 100 and determining the signal strength of the received signal transmitted by the target device 100. After determining the signal strength of the received signal transmitted by the target device 100, the signal receiver generates a corresponding electrical signal and transmits the electrical signal to the second processor 20. The second processor 20 can determine the signal strength of the received signal transmitted by the target device 100 based on the received electrical signal from the signal receiver and compare the magnitude of the signal strength with that of a target signal. In some embodiments, the electronic device 200 further includes a signal receiver for receiving signals transmitted by the target device 100. After receiving the signal transmitted by the target device 100, the signal receiver determines the signal strength of the received signal transmitted by the target device 100 and compares the magnitude relationship between the signal strength and the target signal strength. Then, it generates a corresponding electrical signal and transmits the electrical signal to the second processor 20. The second processor 20 can directly determine the magnitude relationship between the signal strength of the received signal transmitted by the target device 100 and the target signal strength based on the electrical signal received from the signal receiver.

[0072] In one example, electronic device 200 is a mobile phone, target device 100 is a TWS Bluetooth headset, and the housing is a charging case. When the signal strength of the signal transmitted by the TWS Bluetooth headset received by the mobile phone is greater than or equal to the target signal strength, the mobile phone displays a pop-up window prompting the TWS Bluetooth headset's preset information; when the signal strength of the signal transmitted by the TWS Bluetooth headset received by the mobile phone is less than the target signal strength, the mobile phone does not display the TWS Bluetooth headset's preset information.

[0073] Please see Figure 9 and Figure 10 In some implementations, step 021 includes:

[0074] 0211: Analyze the received signal transmitted by the device to be processed to determine whether the device to be processed is the target device 100;

[0075] 0213: When the device to be processed is the target device 100, it is determined that the signal transmitted by the target device 100 has been received.

[0076] The prompting method described above can be implemented by the target device 100 of this application. Specifically, the second processor 20 is used to parse the received signal transmitted by the device to be processed to determine whether the device to be processed is the target device 100, and to determine, when the device to be processed is the target device 100, that a signal transmitted by the target device 100 has been received.

[0077] The prompting method described above can be implemented by the prompting device 22 of this application. Specifically, the receiving module 222 further includes a second parsing unit 2222 and a determining unit 2224. The second parsing unit 2222 is used to parse the received signal transmitted by the device to be processed to determine whether the device to be processed is the target device 100. The determining unit 2224 is used to determine that a signal transmitted by the target device 100 has been received when the device to be processed is the target device 100.

[0078] This prevents the system from incorrectly displaying the target device 100's preset information when the signal strength of a received signal from a non-target device 100 is greater than or equal to the target signal strength, thus avoiding disturbance to the user. It is understood that the device to be processed is a device capable of transmitting signals that can be received by the electronic device 200. If the electronic device 200 immediately displays the target device 100's preset information when the signal strength of any received signal from the target device is greater than or equal to the target signal strength, it may cause problems such as the user receiving the prompt even when the target device 100 is not in use, thus disturbing the user and reducing the user experience. Therefore, it is necessary to determine whether the received signal is transmitted by the target device 100.

[0079] Specifically, the received signal transmitted by the device to be processed includes the device's identification information, which may include device ID, device model, device name, etc. By parsing the identification information, it can be determined whether the device to be processed is the target device 100. Understandably, the signal can be configured to be packaged and transmitted according to a proprietary protocol, so that the target device 100 can be determined based on the protocol of the signal.

[0080] Please see Figure 11 In some implementations, the signal includes identification information of the target device 100, and step 023 includes:

[0081] 0237: Determine whether to prompt the target device 100 with identification information based on the signal strength of the received signal.

[0082] The prompting method described above can be implemented by the target device 100 of this application. Specifically, the second processor 20 is used to determine whether to prompt the target device 100 with identification information based on the signal strength of the received signal.

[0083] The prompting method described above can be implemented by the prompting device 22 of this application. Specifically, the determining module 224 is used to determine whether to prompt the identification information of the target device 100 based on the signal strength of the received signal.

[0084] In this way, the user can determine whether to connect to the target device 100 based on the identification information of the target device 100 provided.

[0085] Specifically, the identification information may include device ID, device model, device name, etc. In some embodiments, the identification information of the target device 100 may be prompted via voice or pop-up window. In some embodiments, a connection button is provided simultaneously with prompting the identification information of the target device 100. When the connection button is triggered, the electronic device 200 connects to the target device 100, thereby enabling data transmission between the electronic device 200 and the target device 100. In some embodiments, after the electronic device 200 connects to the target device 100 once, if the same electronic device 200 determines that the signal strength of the signal transmitted by the same target device 100 is greater than the target signal strength the next time it receives the signal, the same electronic device 200 may not prompt the identification information of the same target device 100 again, and the same electronic device 200 may directly connect to the same target device 100. Alternatively, a connection success message may be displayed upon successful connection, because both parties retain connection information, such as pairing keys, after the initial connection, allowing for direct connection establishment in subsequent connections. Therefore, a connection success message can be displayed directly without requiring the user to click to establish a connection. Furthermore, in some embodiments, while displaying the identification information of the target device 100 and providing a connection button, an optional box is also provided. When the optional box is selected, if the same electronic device 200 determines that the signal strength of the signal received from the same target device 100 is greater than the target signal strength, the same electronic device 200 will no longer display the identification information of the same target device 100, and the same electronic device 200 will directly connect to the same target device 100. If the optional box is not selected, if the same electronic device 200 determines that the signal strength of the signal received from the same target device 100 is greater than the target signal strength, the same electronic device 200 will still display the identification information of the same target device 100, the connection button, and the optional box. When the connection button is triggered, the same electronic device 200 will connect to the same target device 100 again.

[0088] 033: Electronic device 200 receives the signal transmitted by target device 100 and determines whether to prompt the target device 100 with preset information based on the signal strength of the received signal.
