[0029] The following is combined with Figures 1 to 11 , the communication circuit, wireless device, communication method, apparatus and readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0030] In some embodiments of the present application, a communication circuit is provided. Figure 1 A circuit diagram of a communication circuit provided in some embodiments of the present application is shown. Figure 1As shown, the communication circuit 100 is applied to a wireless device, and the communication circuit 100 includes: a switch element K, the switch element K includes a first static contact 103 and a second static contact 104, and the first static contact 103 is connected to a signal source; a power amplifier PA, the input end of the power amplifier PA is connected to a moving contact 107 of the switch element K; a coupler CPL, the coupler CPL includes a first path 105 and a second path 106, the first path 105 is coupled to the second path 106, the first end of the first path 105 is electrically connected to the output end of the power amplifier PA, the second end of the first path 105 is connected to the signal antenna ANT, and the first end of the second path 106 is grounded; a frequency selection network 101, the frequency selection network 101 The first end of the frequency selection network 101 is connected to the second end of the second passage 106, and the second end of the frequency selection network 101 is connected to the second static contact 104; wherein the moving contact 107 is alternately connected to the first static contact 103 and the second static contact 104; when the first static contact 103 is connected to the moving contact 107, a first signal is transmitted through the signal antenna ANT, the first signal is a signal output by the signal source after being amplified, and the first signal is used to establish a communication connection with the electronic device; when the second static contact 104 is connected to the moving contact 107, a second signal is transmitted through the signal antenna ANT, the second signal is a signal formed by self-excited oscillation of the signal output by the signal source, and the second signal is used for the electronic device to locate the wireless device.

[0031] In the embodiment of the present application, the communication circuit 100 includes a switch element K, a power amplifier PA and a coupler CPL. The switch element K includes a first static contact 103, a second static contact 104 and a moving contact 107. The moving contact 107 can be switched to connect with the first static contact 103 or the second static contact 104. The first static contact 103 of the switch element K is connected to the signal source, that is, the first static contact 103 of the switch element K is used to receive the signal from the signal source, and the moving contact 107 of the switch element K is connected to the input end of the power amplifier PA. The coupler CPL includes a first path 105 and a second path 106. The first path 105 and the second path 106 are coupled, and the two ends of the first path 105 are respectively connected to the power amplifier PA and the signal antenna ANT, and the two ends of the second path 106 are respectively electrically connected to the ground end and the second static contact 104 of the switch element K. The second path 106 of the coupler CPL is an attenuation loop, which can feed back the signal output from the output end of the power amplifier PA to the input end, so as to close the feedback loop of the signal path and complete the self-oscillation to form a second signal.

[0032] Exemplarily, the first signal is a paging signal, and the second signal is a pulse signal.

[0033] It should be noted that the coupler CPL needs to be set to a specific coupling degree so that the second path 106 of the coupler CPL can feed back the signal from the output end of the power amplifier PA to the input end.

[0034] Specifically, when the first static contact 103 is connected to the moving contact 107, the signal output by the signal source is transmitted to the power amplifier PA for amplification through the switch element K, and the first signal output from the output end of the power amplifier PA is transmitted through the signal antenna ANT. When the moving contact 107 is switched to be connected to the second static contact 104, the signal formed in the second path 106 of the coupler CPL is fed back to the input end of the power amplifier PA, and the second signal output from the output end of the power amplifier PA is transmitted through the signal antenna ANT.

[0035] In the embodiment of the present application, the switch element K may be a controllable single-pole double-throw switch, which can control the moving contact 107 of the switch element K to switch between connecting to the first static contact 103 and connecting to the second static contact 104, so that the transmitting antenna switches between transmitting the first signal and transmitting the second signal. The frequency selection network 101 is connected to the connection of the second passage 106 of the coupler CPL. Specifically, the frequency selection network 101 is connected between the second static contact 104 of the switch element K and the second end of the second passage 106 of the coupler CPL. The signal fed back from the second passage 106 of the coupler CPL is fed back to the second static contact 104 of the switch element K after being frequency-selected by the frequency selection network 101, and is transmitted outwardly through the switch element K, the power amplifier PA, and the signal antenna ANT.

[0036] Exemplarily, the frequency selection network 101 may be an LC (inductor-capacitor) frequency selection network 101 .

[0037] In the embodiment of the present application, by setting a frequency selection network 101 between the second passage 106 of the coupler CPL and the second static contact 104 of the switch element K, through the setting of the frequency selection network 101, the resonant frequency of the second signal can be designed, so that the coupler CPL, the switch element K and the frequency selection network 101 form a VCO (voltage controlled oscillator) circuit that realizes a specific frequency.

[0038] Specifically, the communication antenna switches between sending the first signal and the second signal by controlling the connection between the static contact of the switch element K and the first moving contact 107 and the second moving contact 107. Due to the alternating switching of the first static contact 103, the second static contact 104 and the moving contact 107 of the switch element K, the second signal is transmitted through the signal pulse. The duty cycle of the second signal is related to the alternating switching frequency of the switch element K. By controlling the alternating switching frequency of the switch element K, the second signal is a pulse signal with a certain duty cycle.

[0039] Exemplarily, when the second signal transmitted by the signal antenna ANT is received by the electronic device, the electronic device can locate the position of the wireless device based on the second signal, and the electronic device can navigate the user to the wireless device based on the located positioning information; when the electronic device can receive the first signal, the electronic device can communicate with the wireless device through the first signal.

[0040] In the embodiment of the present application, the communication circuit 100 can be set in the wireless device, and the wireless device can be connected to the electronic device through the communication circuit 100. When the wireless device is connected to the electronic device for normal communication, the first static contact 103 of the switch element K is connected to the moving contact 107, and the wireless device communicates with the electronic device through the first signal. When the wireless device is disconnected from the electronic device and the reconnection fails, the wireless device controls the moving contact 107 of the switch element K to alternately connect with the first static contact 103 and the second static contact 104, so that the wireless device transmits the second signal, so that the electronic device can search for the location of the wireless device through the second signal.

[0041] In the embodiment of the present application, since the second signal is a single-frequency signal, the actual bandwidth is relatively small, and the bandwidth of the stable second signal is only at the KHz level, the limit sensitivity is improved, thereby expanding the search range of the electronic device for the wireless device based on the second signal transmitted by the wireless device. Specifically, the sensitivity calculation formula (1) is as follows:

[0042] Sen=-174dBm / Hz+10lgBW+NF+SNR; (1)

[0043] Among them, Sen is the sensitivity, -174 is the noise density of the background noise, NF is the noise factor, BW is the carrier bandwidth of the transmitted signal, and SNR is the signal-to-noise ratio.

[0044] It should be noted that the second path 106 of the coupler CPL in the communication circuit 100 forms a feedback circuit, so that the communication circuit 100 can generate a second signal, and the second signal does not have a secondary amplitude modulation and frequency modulation operation, and only carries the duty cycle synchronization information of the carrier itself, which can effectively improve the electronic device's recognition accuracy of the wireless device position based on the second signal. Since the bandwidth of the second signal is relatively narrow, it can bypass the limitations of the communication protocol, allowing the electronic device and the wireless device to communicate end-to-end with narrowband encryption, thereby improving sensitivity.

[0045] Figure 2 The identifiable ranges of the first signal and the second signal provided in some embodiments of the present application are shown. Figure 2 As shown, the first signal may be a Bluetooth communication signal, the second signal may be a pulse signal, and the recognizable range of the second signal is greater than the recognizable range of the first signal.

[0046] Exemplarily, the search range of the electronic device for searching for wireless devices through the first signal of the protocol communication is 10 meters, and the search range of the electronic device for searching for wireless devices through the second signal is 100 meters.

[0047] It should be noted that in the related art, when the electronic device is disconnected from the wireless device, it records the location of the wireless device through GPS (Global Positioning System), and manually moves to the vicinity of the recorded location. The electronic device pages the wireless device through existing protocol communication, and then establishes a communication connection. In the embodiment of the present application, there is no need to establish a stable connection. It is only necessary for the electronic device to receive the second signal sent by the wireless device. The electronic device can guide the user to the wireless device based on the signal strength of the second signal received at different locations, avoiding the problem of inaccurate GPS positioning in the related art.

[0048] In the embodiment of the present application, a switch element K is provided in the communication circuit 100, and the moving contact 107 of the switch element K is connected to the power amplifier PA, and the first static contact 103 of the switch element K is connected to the signal source, and the second static contact 104 of the switch element K is connected to the second path 106 of the coupler CPL, so that when the moving contact 107 of the switch element K switches the conductive state with the first static contact 103 and the second static contact 104, the signal output by the signal source can be self-oscillated to form a second signal, and the communication circuit 100 is configured in a wireless device. When the wireless device is disconnected from the electronic device, the wireless device alternately transmits the first signal and the second signal, and controls the electronic device to locate the position of the wireless device based on the second signal, and when the electronic device is close to the wireless device, the wireless device communicates with the wireless device based on the first signal, thereby improving the search range of the electronic device for the wireless device.

[0049] In some embodiments of the present application, the communication circuit 100 further includes: a filter SAW, a first end of the filter SAW is connected to the output end of the power amplifier PA, and a second end of the filter SAW is connected to the first path 105 .

[0050] In the embodiment of the present application, the filter SAW is arranged between the power amplifier PA and the first path 105 of the coupler CPL, and the filter SAW can filter the signal output by the power amplifier PA.

[0051] Specifically, when the moving contact 107 of the switch element K is connected to the first static contact 103, the signal transmitted by the signal source is amplified by the power amplifier PA, and then transmitted to the filter SAW for filtering, and the first signal is emitted outwardly through the signal antenna ANT. When the moving contact 107 of the switch element K is switched to be connected to the second static contact 104, the signal formed by the self-excited oscillation is amplified by the power amplifier PA, and then transmitted to the filter SAW for filtering, and the second signal is emitted outwardly through the signal antenna ANT.

[0052] In the embodiment of the present application, by providing a filter SAW in the communication circuit 100 , the signal output by the power amplifier PA can be filtered.

[0053] like Figure 1 As shown, in some embodiments of the present application, the communication circuit 100 also includes: a first power supply VIO and a second power supply VCC, the first power supply VIO is connected to the switch element K for powering the switch element K; the second power supply VCC is connected to the power amplifier PA for powering the power amplifier PA.

[0054] In the embodiment of the present application, the first power supply VIO is used to power the switch element K, and the second power supply VCC is used to power the power amplifier PA. By setting the first power supply VIO and the second power supply VCC in the communication circuit 100, the switch element K and the power amplifier PA can operate stably.

[0055] like Figure 1 As shown, in some embodiments of the present application, the communication circuit 100 also includes: a controller 102, a first output terminal of the controller 102 is connected to the first static contact 103, and a second output terminal of the controller 102 is connected to the control terminal of the switch element K.

[0056] In the embodiment of the present application, a controller 102 is further provided in the communication circuit 100. The controller 102 can serve as a signal source in the communication circuit 100 and also as a control source of the switch element K.

[0057] Specifically, the first output end of the controller 102 is used to output a communication signal, that is, the first output end of the communication circuit 100 is connected to the first static contact 103 of the switch element K as a signal source. The second output end of the controller 102 is used to output a control signal, and the control signal can control the on-off state of the switch element K. When the wireless device maintains a communication connection with the electronic device, the first static contact 103 of the switch element K maintains a conductive state with the moving contact 107. When the wireless device is disconnected from the electronic device and the reconnection fails, the moving contact 107 of the switch element K is controlled to switch between being conductive with the first static contact 103 and being conductive with the second static contact 104, so that the communication circuit 100 transmits a second signal to the outside, so that the electronic device can search for the second signal to locate the wireless device.

[0058] like Figure 1 As shown, TXIN in the controller 102 is a first output terminal, and GPIO in the controller 102 is a second output terminal.

[0059] like Figure 1 As shown, when the moving contact 107 of the switch element K is connected to the second static contact 104, the first output terminal is disconnected, so that the communication circuit 100 no longer sends out the first signal of the wireless protocol paging, but forms a VCO circuit with the power amplifier PA. The design of the frequency selection network 101 allows the VCO to oscillate at the frequency with the highest efficiency of the signal antenna ANT, and the attenuation loop provided by the coupler CPL allows the signal to be fed back from the output terminal to the input terminal, realizing the feedback closed loop of the signal path, completing the self-excited oscillation, and realizing the emission of the second signal saturated at a specific frequency, so that the power amplifier PA can work at its maximum capacity.

[0060] In the embodiment of the present application, a controller 102 that can serve as a signal source is provided in the communication circuit 100, and the controller 102 can also control the on-off state of the switch element K. When the wireless device equipped with the communication circuit 100 communicates wirelessly with the electronic device, it can continuously transmit the first signal for communication, and when the wireless device is disconnected from the electronic device, it can automatically transmit the first signal and the second signal alternately, thereby improving the search range of the electronic device for the wireless device.

[0061] like Figure 1 As shown, in some embodiments of the present application, the communication circuit 100 further includes: a resistor R, a first end of the resistor R is connected to the first end of the second path 106, and a second end of the resistor R is grounded.

[0062] In the embodiment of the present application, the first end of the second path 106 is grounded through the resistor R, and the resistor R is connected between the first end of the second path 106 and the ground end as the load of the second path 106 of the coupler CPL, so that the second path 106 of the coupler CPL and the frequency selection network 101 and the switch element K can form a feedback loop, and the signal formed by the self-excited oscillation is transmitted to the power amplifier PA, thereby improving the stability of the communication circuit 100 in transmitting the second signal.

[0063] Figure 3 2 shows a waveform diagram of the first signal and the second signal provided in some embodiments of the present application, such as Figure 3 As shown, t0 is the transmission duration of the second signal, (1-t0) is the transmission duration of the first signal, wherein 1 represents one cycle, and the duration of one cycle ranges from 10 microseconds to 900 milliseconds.

[0064] In some embodiments of the present application, a wireless device is provided. Figure 4: shows a structural block diagram of a wireless device provided in some embodiments of the present application, such as Figure 4 As shown, the wireless device 400 includes: a communication circuit 100, which is the communication circuit in any of the above embodiments, and thus has all the beneficial technical effects of the communication circuit 100 in any of the above embodiments, which will not be described in detail herein.

[0065] Exemplarily, the wireless device 400 includes at least one of the following: a wireless headset, a smart watch, a smart bracelet, etc.

[0066] In some embodiments of the present application, a communication method is provided. Figure 5 One of the flow charts of the communication method provided in some embodiments of the present application is shown, such as Figure 5 As shown, the communication method is applied to the wireless device in any of the above embodiments, and the communication method includes:

[0067] Step 502, when the communication connection with the electronic device is disconnected, the moving contact of the switch element is controlled to be alternately connected with the first static contact and the second static contact, so as to alternately transmit the first signal and the second signal through the signal antenna;

[0068] In an embodiment of the present application, a communication circuit can be provided in a wireless device, and the wireless device can be connected to an electronic device through the communication circuit. When the wireless device is connected to the electronic device for normal communication, the first static contact of the switch element is connected to the moving contact, and the wireless device communicates with the electronic device through a first signal. When the wireless device is disconnected from the electronic device and reconnection fails, the wireless device controls the moving contact of the switch element to alternately connect with the first static contact and the second static contact, so that the wireless device transmits a second signal, so that the electronic device can search for the location of the wireless device through the second signal.

[0069] Specifically, when the wireless device is communicating with the electronic device, the wireless device controls the moving contact of the switch to maintain connection with the first static contact, so that the wireless device maintains communication connection with the electronic device through the first signal. When the electronic device is disconnected from the wireless device, the wireless device attempts to reconnect with the electronic device through the first signal, and maintains communication connection with the electronic device through the first signal after the reconnection is successful. After the electronic device fails to reconnect with the wireless device, the wireless device controls the moving contact of the switch to alternately conduct with the first static contact and the second static contact, thereby alternately transmitting the first signal and the second signal, so that the electronic device searches and locates the wireless device through the alternately transmitted first signal and the second signal.

[0070] It should be noted that as the distance between the wireless device and the electronic device becomes farther and farther, the communication connection between the wireless device and the electronic device will be disconnected. After the disconnection, the electronic device and the wireless device first try to reconnect through the wireless communication protocol. If the reconnection fails, the wireless device turns on the VCO mode, that is, the moving contact of the switch element is alternately connected to the first static contact and the second static contact.

[0071] Step 504: When the communication connection with the electronic device is successfully reconnected, the moving contact of the switch element is controlled to be connected to the first static contact, so as to establish a communication connection with the electronic device through the signal antenna.

[0072] In the embodiment of the present application, after the wireless device successfully reconnects with the electronic device, the wireless device controls the moving contact of the switch element to remain connected to the first static contact again, thereby establishing a communication connection with the electronic device through the first signal transmitted by the signal antenna.

[0073] Specifically, when the wireless device is in communication connection with the electronic device, the moving contact of the control switch is connected to the first static contact, so as to communicate normally with the electronic device through the first signal. When the wireless device is disconnected from the electronic device and cannot be reconnected through the first signal, the moving contact is alternately controlled to be connected to the first static contact and the second static contact, and the wireless device alternately transmits the first signal and the second signal at this time, thereby increasing the search range of the electronic device for the wireless device.

[0074] In an embodiment of the present application, a switch element is provided in a communication circuit, a moving contact of the switch element is connected to a power amplifier, a first static contact of the switch element is connected to a signal source, and a second static contact of the switch element is connected to a second path of a coupler, so that when the moving contact of the switch element switches to a conductive state with the first static contact and the second static contact, a signal output by the signal source can be self-oscillated to form a second signal, and the communication circuit is configured in a wireless device. When the wireless device is disconnected from the electronic device, the wireless device alternately transmits the first signal and the second signal, and controls the electronic device to locate the position of the wireless device based on the second signal, and when the electronic device is close to the wireless device, communicates with the wireless device based on the first signal, thereby improving the search range of the electronic device for the wireless device.

[0075] In some embodiments of the present application, a communication method is provided. Figure 6 FIG. 2 shows a flow chart of a communication method provided in some embodiments of the present application. Figure 6 As shown, the communication method is applied to an electronic device, and the communication method includes:

[0076] Step 602, receiving a second signal transmitted by the wireless device when the communication connection with the wireless device is disconnected;

[0077] In the embodiment of the present application, when the electronic device is disconnected from the wireless device and fails to reconnect through the wireless communication protocol, the electronic device can determine that the wireless device has entered the VCO mode, and then the electronic device starts to search and receive the second signal, which is a signal formed by the coupler, switch and frequency selection network in the wireless device to realize the transmission of the VCO circuit of a specific frequency. Since the second signal is a single-frequency signal, the actual bandwidth is relatively small, and the bandwidth of the stable second signal is only KHz, which improves the limit sensitivity, thereby expanding the electronic device's search range for the wireless device based on the second signal transmitted by the wireless device.

[0078] Step 604, receiving a first signal transmitted by a wireless device when the signal strength of the second signal is greater than or equal to a strength threshold;

[0079] In the embodiment of the present application, after the electronic device receives the second signal, it can extract the signal strength in the second signal and compare the extracted signal strength with the strength threshold. When the signal strength is greater than or equal to the strength threshold, it can be determined that the electronic device can communicate with the wireless device through the wireless communication protocol at this time. Since the wireless device alternately sends the first signal and the second signal in the VCO mode, and the first signal is a wireless communication protocol signal, at this time, the electronic device is controlled to receive the first signal transmitted by the wireless device.

[0080] Step 606: reconnecting the communication connection with the wireless device through the first signal.

[0081] In the embodiment of the present application, after the electronic device receives the first signal, it is determined that the electronic device has been reconnected with the wireless device. At this time, the electronic device can complete the reconnection with the wireless device through the first signal.

[0082] Exemplarily, after the electronic device and the wireless device complete the reconnection through the first signal, the electronic device can notify the wireless device that the reconnection is completed, or when the wireless device determines through the first signal that the reconnection has been completed, the wireless device connects the first static contact and the moving contact of the switch element, thereby continuing to transmit data with the electronic device through the wireless communication protocol.

[0083] In an embodiment of the present application, a switch element is provided in a communication circuit of a wireless device, a moving contact of the switch element is connected to a power amplifier, a first static contact of the switch element is connected to a signal source, and a second static contact of the switch element is connected to a second path of a coupler, so that when the moving contact of the switch element switches to a conductive state with the first static contact and the second static contact, a signal output by the signal source can be self-oscillated to form a second signal, and the communication circuit is configured in the wireless device. After the electronic device is disconnected from the wireless device and fails to reconnect, the electronic device starts to search for and receive the second signal, and controls the electronic device to search for the location of the wireless device based on the second signal, and when the electronic device is close to the wireless device, communicates with the wireless device based on the first signal, thereby improving the search range of the electronic device for the wireless device.

[0084] In some embodiments of the present application, after reconnecting with the wireless device through the first signal to establish a communication connection, the communication method further includes:

[0085] In the case that the communication connection reconnection with the wireless device fails, the strength threshold is increased, and the step of receiving the second signal transmitted by the wireless device is returned to be executed until the communication connection between the electronic device and the wireless device is successfully reconnected.

[0086] In an embodiment of the present application, when a reconnection failure occurs during a process in which an electronic device reconnects with a wireless device through a first signal, the strength threshold corresponding to the second signal is increased, and the step of receiving the second signal transmitted by the wireless device is returned to be executed, and the signal strength of the received second signal is compared with the increased strength threshold. After the signal strength of the second signal is greater than the increased strength threshold, the first signal is received again, and an attempt is made to reconnect with the wireless device through the first signal. If the reconnection is successful, the reconnection step is completed. If the reconnection fails, the above steps are repeated until the reconnection is successful.

[0087] It should be noted that when the user carries the electronic device toward the wireless device, the electronic device can determine whether it can reconnect to the wireless device through the first signal by using the signal strength of the second signal and the strength threshold, and attempts to reconnect after determining that the signal strength is greater than the strength threshold. If the reconnection fails, it is determined that although the signal strength of the second signal is greater than or equal to the strength threshold, it is impossible to reconnect to the wireless device through the first signal, and it is necessary to return to continue searching and locating the wireless device based on the second signal. Therefore, after increasing the strength threshold, return to the step of searching and locating the wireless device based on the second signal.

[0088] In an embodiment of the present application, after the electronic device determines that it can reconnect with the wireless device through the first signal through the signal strength of the second signal, it attempts to reconnect with the wireless device through the first signal. After the reconnection fails, the strength threshold is increased, and the process returns to execute the step of determining whether it can reconnect with the wireless device through the first signal through the signal strength of the second signal, thereby ensuring that the electronic device can stably search and locate the wireless device, thereby improving the efficiency of the electronic device in locating the wireless device.

[0089] In some embodiments of the present application, after receiving the second signal transmitted by the wireless device, the communication method further includes:

[0090] When the signal strength of the second signal is less than the strength threshold, prompt information is output to prompt the user to move in a target direction, where the target direction is a direction in which the signal strength of the second signal increases as the electronic device moves.

[0091] In an embodiment of the present application, after the electronic device receives the second signal and extracts the signal strength of the second signal, it can report the user's signal strength data based on the energy of the received second signal, and output prompt information to guide the user to move in the direction of a larger signal strength value, help the user narrow the search range, prompt the moving direction, and further improve the efficiency of reconnecting the electronic device with the wireless device.

[0092] Exemplarily, the prompt information includes audio information and video information, and guides the user to move to the location of the wireless device by means of navigation audio and navigation video.

[0093] In some embodiments of the present application, receiving a second signal transmitted by a wireless device includes: adjusting a signal receiving frequency of the electronic device; receiving the second signal according to the signal receiving frequency, wherein the adjusted signal receiving frequency matches the signal frequency of the second signal.

[0094] In the embodiment of the present application, before the electronic device receives the second signal, it is necessary to adjust the VCO frequency inside the electronic device, that is, the signal receiving frequency, so that the electronic device can demodulate the second signal transmitted by the wireless device in the VCO mode, thereby demodulating the pulse waveform and back-end sampling identification information. By adjusting the signal receiving frequency of the electronic device, the stability of the electronic device receiving the second signal transmitted by the wireless device can be improved.

[0095] Exemplarily, after the electronic device is disconnected from the wireless network and fails to reconnect through the wireless communication protocol, the user actively controls the electronic device to enter a mode of searching for wireless devices, and adjusts the signal receiving frequency through the SDR (software radio) of the electronic device so that the electronic device can receive the second signal.

[0096] In some specific implementations, a device reconnection method is proposed. Figure 7A schematic diagram of a device reconnection method provided in some embodiments of the present application is shown. Figure 7 As shown, the communication method is applied to the wireless device and the electronic device in any of the above embodiments, and the device reconnection method includes:

[0097] Step 702, the wireless device signal is disconnected;

[0098] Step 704, determine whether Bluetooth can be reconnected, if it is determined to be, execute step 726, otherwise execute step 706;

[0099] Step 706, the wireless device sends the first signal and the second signal alternately;

[0100] Step 708, whether the electronic device searches for wireless devices, if it is determined to be, execute step 710, otherwise, execute step 724;

[0101] Step 710, receiving a second signal and displaying the signal strength;

[0102] Step 712, the signal strength reaches a strength threshold;

[0103] Step 714, whether to enter Bluetooth mode, if it is judged to be yes, execute step 716, otherwise execute step 718;

[0104] Step 716, whether Bluetooth connection is established, if yes, execute step 722, otherwise execute step 718;

[0105] Step 718, prompting the user to continue searching for wireless devices;

[0106] Step 720, increase the intensity threshold, and return to step 710;

[0107] Step 722, the wireless device sends only the first signal;

[0108] Step 724, waiting for the wireless device to enter the Bluetooth communication range of the first signal;

[0109] Step 726: The wireless device reconnects to the electronic device via Bluetooth.

[0110] Exemplarily, the wireless device may be a wireless headset, and the electronic device may be a mobile phone.

[0111] In the embodiment of the present application, the second signal is different from the modulated signal in the protocol bandwidth. In the new mode of searching for wireless devices, conventional protocol communication is not adopted, and no AM / FM information is carried. Only the opening and closing time of the single-pole double-throw switch is controlled. Different from the traditional mode of the power amplifier normally transmitting modulation information, the power amplifier is in the state of self-excitation and shutdown, and only the second signal carrying the duty cycle information of the fixed switching time is carried. The second signal of the single frequency point can achieve KHz level bandwidth. Compared with the MHz of the protocol bandwidth, the narrow bandwidth communication can significantly improve the receiving sensitivity. The traditional broadcast paging method has a small coverage range, and the paging method is traditional. No matter which prompt method is used to attract the user's attention, it cannot change the bandwidth bottleneck of the hardware protocol communication and the limitation of small coverage range. The present application adopts a new communication method, which significantly improves the signal coverage range without increasing the hardware cost; the theoretical coverage distance increases, and the theoretical signal bandwidth is reduced by an order of magnitude, which is theoretically 1000 times. The sensitivity calculation formula can estimate that the noise floor is reduced by 30dB, and the theoretical sensitivity is increased by 30dB. In an open area without obstructions, the theoretical communication distance can be increased by 10 times compared with the traditional protocol communication distance.

[0112] For example, if the wireless headset is lost in a parking lot, the GPS signal of the wireless headset can only indicate an approximate range, which is beyond the connection distance of Bluetooth communication. However, within the coverage range of the second signal of the wireless headset, the user can follow the signal strength of the second signal displayed in real time on the mobile phone. The mobile phone can guide the user to move towards the headset according to the signal strength at different points, and then the headset can be found by guiding the signal strength, or other traditional methods can be used to find the headset, such as entering the communication range of the headset's Bluetooth connection / protocol connection to reconnect the headset and the mobile phone.

[0113] For example, if a wireless headset is lost in a teaching building or in a scenario where there are upstairs or downstairs or multiple floors, since the GPS points of the wireless headset are flat, the connection of Bluetooth communication / protocol communication can be vertical. If it is not within the range of Bluetooth / protocol communication, at this time, the wireless headset transmits a second signal in VCO mode, and the advantage of the second signal's long-distance coverage can be fully utilized to help the user find the headset. If it is within the Bluetooth communication range, but the Bluetooth connection does not indicate the location, in theory, it can be connected within the spherical range, which makes it impossible for the user to distinguish which floor or which direction to look for, but the second signal transmitted in VCO mode can give the correct direction guidance according to the signal strength at different points, helping the user to accurately and efficiently locate the specific location.

[0114] The communication method provided in the embodiment of the present application can be executed by a communication device. The communication method provided in the embodiment of the present application is described by taking a communication device executing the communication method as an example.
