[0098] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0099] Electronic devices and styluses are connected via Bluetooth. Styluses can be used to write notes, record and organize ideas, and can also be used for drawing, such as painting and graffiti. At the same time, styluses also support short video remote control, virtual laser and other functions. Styluses can improve our work efficiency and quality of life, making our lives more convenient and interesting.

[0100] When an electronic device is connected to a stylus pen, it is easily interfered by noise signals in the environment. In order to improve the anti-interference ability of the stylus pen, when the interference is more serious, the electronic device and the stylus pen can be adjusted to other working frequencies.

[0101] In a related technology, the screen of the electronic device sends an uplink signal to the stylus pen to achieve frequency hopping (frequency adjustment) of the electronic device and the stylus pen.

[0102] In another related technology, the electronic device and the stylus perform frequency hopping via Bluetooth. That is, when the screen of the electronic device detects a noise signal (for example, noise is generated when the charging cable is plugged in), a frequency hopping request is initiated to notify the BSP touch (board support package touch) of the electronic device, and the frequency hopping parameters are sent to the Bluetooth module of the electronic device via the BSP touch. The frequency hopping request and frequency hopping parameters are then sent to the stylus via the Bluetooth module. After receiving the frequency hopping request and frequency hopping parameters, the stylus performs frequency hopping and replies the ACK (Acknowledgement) of the completion of the frequency hopping to the Bluetooth module of the electronic device. The ACK is returned to the BSP touch via the Bluetooth module, and the BSP touch returns the ACK to the screen, and the frequency adjustment is completed.

[0103] Although both of the above-mentioned two related technologies can realize frequency hopping of the electronic device and the stylus, since the electronic device and the stylus are two clock systems, the times of the two may not be unified. There is a delay in the frequency hopping instruction (frequency hopping request or uplink signal) sent by the electronic device to the stylus, which makes the frequency hopping response of the stylus relatively slow, resulting in the problem that the stylus function cannot be realized because the operating frequencies of the electronic device and the stylus are consistent.

[0104] In view of the above-mentioned problem, a frequency adjustment method is provided in an embodiment of the present disclosure. The electronic device first obtains a delay time consumed in a data transmission process between the electronic device and the stylus pen, and then sends a data synchronization request to the stylus pen. The data synchronization request includes a first moment, a second moment and a delay time. The first moment is the moment when the electronic device sends the data synchronization request, and the second moment is the moment when the electronic device adjusts the frequency. The frequency of the electronic device is adjusted at the second moment. At the same time, the stylus pen determines an eighth moment according to the received data synchronization request, and adjusts the frequency of the stylus pen at the eighth moment. The frequency adjustment moments of the electronic device and the stylus pen are calibrated by the delay time, so that the electronic device and the stylus pen perform frequency adjustment at the same moment, thereby ensuring that the operating frequencies of the electronic device and the stylus pen are consistent, and reducing the problem that the stylus pen function cannot be realized due to inconsistent frequencies between the two.

[0105] The disclosed embodiments are applied to an electronic device and a stylus. The electronic device may be a mobile phone, a tablet computer, a laptop computer, a television, or other device that can interact with the stylus. The stylus may also be called a touch pen or an active pen. The electronic device is connected to the stylus. The stylus may be connected to at least one electronic device at the same time. For example, the stylus may be connected to a tablet computer, a laptop computer, and a television at the same time. Optionally, the electronic device and the stylus are connected via Bluetooth.

[0106] Below through Figure 1 and Figure 2 In the embodiments, the frequency adjustment process is described from the perspectives of the electronic device and the stylus respectively.

[0107] Figure 1 is a flow chart of a frequency adjustment method according to an exemplary embodiment, which is executed by an electronic device, see Figure 1 , the method comprises the following steps:

[0108] Step S101, obtaining a delay time, where the delay time is the time taken for the data transmission process between the electronic device and the stylus.

[0109] The delay duration is obtained by the electronic device before frequency hopping and is used to calibrate the delay during the frequency hopping process. The delay duration is the duration of the data transmission process between the electronic device and the stylus, that is, the duration of the process of the electronic device sending data to the stylus once.

[0110] Optionally, considering that the time consumed by the data transmission process between the electronic device and the stylus may be different in different environments, the electronic device can calculate the delay time in real time to ensure the validity of the delay time. The implementation method of calculating the delay time is as follows: Figure 3Alternatively, in order to obtain the delay time more quickly and reduce the amount of calculation, the delay time may be pre-stored in the electronic device. In this case, the delay time may be determined by a technician based on experimental verification.

[0111] Step S102, sending a data synchronization request to the stylus, the data synchronization request includes a first time, a second time and a delay time, the first time is the time when the electronic device sends the data synchronization request, and the second time is the time when the electronic device adjusts the frequency.

[0112] The data synchronization request is used to instruct the stylus pen and the electronic device to adjust the frequency at the same time, and the same time means that the local clock of the stylus pen and the local clock of the electronic device are the same time in the external environment. For example, the local clock of the stylus pen is 8 o'clock and the local clock of the electronic device is 9 o'clock, but at this time, it is the same time in the external environment, then the 8 o'clock of the local clock of the stylus pen and the 9 o'clock of the local clock of the electronic device are the same time. In addition, the time can also be called a time point, a timestamp, a time position, etc.

[0113] The data synchronization request includes a first moment, a second moment, and a delay time. The first moment is the moment when the electronic device sends the data synchronization request, and the second moment is the moment when the electronic device adjusts the frequency. The second moment is an estimated moment. In order to allow the stylus pen and the electronic device to adjust the frequency at the same moment, the second moment must be greater than the moment after the first moment and the delay time are added. That is, the electronic device needs to adjust the frequency of the electronic device after the stylus pen receives the data synchronization request, so as to avoid the electronic device adjusting the frequency before the stylus pen receives the data synchronization request, resulting in inconsistent working frequencies of the electronic device and the stylus. Among them, the first moment and the second moment are the moments of the local clock of the electronic device.

[0114] After the electronic device sends the data synchronization request to the stylus, the stylus can determine a time that is the same as the second time according to the data included in the data synchronization request, and then adjust the frequency of the stylus at the determined time.

[0115] Step S103: adjusting the frequency of the electronic device at the second moment.

[0116] The electronic device sends a data synchronization request, and waits until a second moment to adjust the frequency of the electronic device.

[0117] According to the method provided by the embodiment of the present disclosure, the electronic device first obtains the delay time consumed in the data transmission process between the electronic device and the stylus, and then sends a data synchronization request to the stylus, so that the stylus determines the time to adjust the frequency according to the data synchronization request, and calibrates the frequency adjustment time of the electronic device and the stylus by the delay time, so that the electronic device and the stylus adjust the frequency at the same time, thereby ensuring that the operating frequencies of the electronic device and the stylus are consistent, and reducing the problem that the stylus function cannot be realized due to inconsistent frequencies between the two.

[0118] Figure 2 is a flow chart showing another frequency adjustment method according to an exemplary embodiment, which is executed by a stylus pen, see Figure 2 , the method comprises the following steps:

[0119] Step S201, receiving a data synchronization request sent by an electronic device, the data synchronization request includes a first moment, a second moment and a delay duration, the first moment is the moment when the electronic device sends the data synchronization request, the second moment is the moment when the electronic device adjusts the frequency, and the delay duration is the duration consumed by the data transmission process between the electronic device and the stylus.

[0120] The contents of the data synchronization request and the delay duration refer to the above steps S101 and S102, which will not be repeated here.

[0121] Step S202, obtaining the seventh time, where the seventh time is the time when the data synchronization request is received.

[0122] The seventh moment is the moment of the local clock of the stylus.

[0123] Step S203, determining the eighth moment based on the first moment, the second moment, the delay duration and the seventh moment.

[0124] For the stylus, after receiving the data synchronization request at the seventh moment, the time difference between the moment when the stylus receives the data synchronization request and the moment when the frequency is adjusted can be calculated according to the first moment, the second moment and the delay time carried in the data synchronization request, and then the eighth moment when the frequency is adjusted can be determined according to the time difference and the seventh moment. The eighth moment is the moment of the local clock of the stylus.

[0125] Step S204, adjusting the frequency of the stylus at the eighth moment.

[0126] The stylus waits until the eighth moment and adjusts the frequency of the stylus.

[0127] According to the method provided by the embodiment of the present disclosure, a stylus receives a data synchronization request sent by an electronic device, and the data synchronization request includes a delay time consumed by the electronic device first obtaining a data transmission process between the electronic device and the stylus, a time when the electronic device adjusts a frequency, and a time when the data synchronization request is sent. The stylus determines a time to adjust the frequency according to the data synchronization request, and calibrates the frequency adjustment time of the electronic device and the stylus by the delay time, so that the electronic device and the stylus adjust the frequency at the same time, thereby ensuring that the operating frequencies of the electronic device and the stylus are consistent, and reducing the problem that the stylus function cannot be realized due to inconsistent frequencies between the two.

[0128] The frequency adjustment method provided by the embodiment of the present disclosure includes a delay calibration phase and a frequency hopping phase. Figure 3 and Figure 5 The illustrated embodiment illustrates the process of determining the delay duration in the delay calibration phase and the process of adjusting the frequency in the frequency hopping phase:

[0129] Figure 3 is a flowchart showing a process of determining a delay time according to an exemplary embodiment, which is performed by an electronic device and a stylus, see Figure 3 , the process includes the following steps:

[0130] Step S301: the electronic device sends a delay calibration request to the stylus pen and obtains a third moment, where the third moment is the moment when the electronic device sends the delay calibration request.

[0131] The delay calibration request is used to request calibration of the delay duration between the electronic device and the stylus. While the electronic device sends the delay calibration request to the stylus, it obtains a third time when the electronic device sends the delay calibration request, and the third time is the time of the local clock of the electronic device. For example, see Figure 4 In the schematic diagram of each moment shown, the third moment is the first moment in the process of determining the delay duration.

[0132] In some embodiments, after the electronic device establishes a communication connection with the stylus, the delay calibration request is immediately sent to the stylus. Alternatively, after the electronic device establishes a communication connection with the stylus, the delay calibration request is sent once every preset time period. The preset time period is a preset time period, for example, the preset time period is 20 minutes, 30 minutes, 40 minutes or other time periods.

[0133] Step S302: the stylus receives a delay calibration request sent by the electronic device.

[0134] The stylus receives the delay calibration request sent by the electronic device, and obtains a fourth time when the delay calibration request is received, where the fourth time is the time of the local clock of the stylus. Figure 4The fourth moment is the second moment in the process of determining the delay duration.

[0135] Step S303, the stylus sends a delay calibration response to the electronic device, the delay calibration response includes a fourth moment and a fifth moment, the fourth moment is the moment when the stylus receives the delay calibration request, and the fifth moment is the moment when the stylus sends the delay calibration response.

[0136] After receiving the delay calibration request, the stylus sends a delay calibration response to the electronic device in response to the delay calibration request. The delay calibration response is used to inform the electronic device of the fourth moment and the fifth moment so that the electronic device can determine the delay duration based on the fourth moment and the fifth moment.

[0137] The fifth moment is the moment of sending the delay calibration response, and the fifth moment is the moment of the local clock of the stylus. Figure 4 The fifth moment is the third moment in the process of determining the delay duration. Optionally, it is not possible to add the fifth moment only when sending the delay calibration request. Therefore, before sending the delay calibration response, the fifth moment of sending the delay calibration response is first determined, and the fifth moment is included in the delay calibration response.

[0138] In some embodiments, the delay calibration response includes a first delay calibration response and a second delay calibration response, and step S303 includes: the stylus sequentially sends the first delay calibration response and the second delay calibration response to the electronic device, the first delay calibration response includes the fourth moment, the second delay calibration response includes the fifth moment when the stylus sends the first delay calibration response, and the second delay calibration response is sent by the stylus after the first delay calibration response is sent. That is to say, at the fifth moment, the stylus sends the first delay calibration response to the electronic device, and after sending the delay calibration response, the fifth moment when the delay calibration response is sent can be determined. At this time, the second delay calibration response is sent to the electronic device again. The stylus informs the electronic device of the fourth moment and the fifth moment through two transmissions, so that the electronic device can know the accurate fourth moment and fifth moment, thereby ensuring the accuracy of the fourth moment and the fifth moment, thereby improving the accuracy of the delay duration determined subsequently.

[0139] Step S304, the electronic device receives the delay calibration response sent by the stylus, and obtains a sixth moment, where the sixth moment is the moment when the electronic device receives the delay calibration response.

[0140] The electronic device receives the delay calibration response sent by the stylus, and obtains the sixth time when the delay calibration response is received, where the sixth time is the time of the local clock of the electronic device. Figure 4 , the sixth moment is the fourth moment in the process of determining the delay duration.

[0141] In some embodiments, when the delay calibration response includes a first delay calibration response and a second delay calibration response, step S304 includes: the electronic device sequentially receives the first delay calibration response and the second delay calibration response sent by the stylus. In this case, the sixth moment is the moment when the electronic device receives the first delay calibration response.

[0142] Step S305: The electronic device determines the delay duration based on the third moment, the fourth moment, the fifth moment, and the sixth moment.

[0143] from Figure 4 It can be seen that the delay duration is the time difference between the third moment of the electronic device and the fourth moment of the stylus, or the delay duration is the time difference between the fifth moment of the stylus and the sixth moment of the electronic device. However, since the time of the local clock of the electronic device and the local clock of the stylus are not unified, the delay duration cannot be directly calculated based on the third moment and the fourth moment, or based on the fifth moment and the sixth moment. Therefore, it is necessary to calculate the delay duration based on the third moment, the fourth moment, the fifth moment and the sixth moment.

[0144] In some embodiments, since the sixth moment and the third moment are the same clock moment, and the fifth moment and the fourth moment are the same clock moment, the first time difference between the sixth moment and the third moment and the second time difference between the fifth moment and the fourth moment are determined, and the difference between the first time difference and the second time difference is divided by 2 to obtain the delay duration. Figure 4 The difference between the first time difference and the second time difference is two delay durations, so the difference is divided by 2 to obtain the delay duration.

[0145] It should be noted that the above Figure 3 The embodiment shown is to illustrate the process of obtaining the delay time once. In another embodiment, after the communication connection is established between the electronic device and the stylus, the electronic device obtains the delay time once every preset time. The process of obtaining the delay time each time is the same as the above. Figure 3 The embodiments shown are identical.

[0146] In some embodiments, in the case where the delay duration is obtained once every preset time, the delay duration included in the data synchronization request is the latest obtained delay duration, so that the latest delay duration can be used for delay calibration. Alternatively, the delay duration included in the data synchronization request is the average value of multiple obtained delay durations, which can avoid the influence of some accidental situations and make the delay duration used in delay calibration more accurate.

[0147] According to the method provided by the embodiment of the present disclosure, the electronic device sends a delay calibration request to the stylus pen and receives a delay calibration response returned by the stylus pen, thereby obtaining a third moment when the electronic device sends the delay calibration request, a fourth moment when the stylus pen receives the delay calibration request, a fifth moment when the stylus pen returns the delay calibration response, and a sixth moment when the electronic device receives the delay calibration response. The delay duration is calculated according to the third moment, the fourth moment, the fifth moment, and the sixth moment, so that when the electronic device and the stylus pen perform frequency adjustment, the same moment for frequency adjustment can be determined according to the delay duration, thereby ensuring that the operating frequencies of the electronic device and the stylus are consistent, and reducing the problem of the stylus pen function not being able to be realized due to inconsistent frequencies between the two.

[0148] Figure 5 is a flow chart showing another frequency adjustment method according to an exemplary embodiment, which is performed by an electronic device and a stylus, see Figure 5 , the method comprises the following steps:

[0149] Step S501: the electronic device obtains a delay duration.

[0150] The implementation of step S501 is shown in the above Figure 3 The illustrated implementation will not be described in detail here.

[0151] Step S502: the electronic device detects a noise signal and sends a data synchronization request to the stylus.

[0152] The noise signal is noise that affects the function of the stylus, for example, the noise signal is noise generated when the electronic device is connected to a charger, or noise generated when the electronic device contacts other electronic devices, or environmental noise in the environment where the electronic device is located.

[0153] When the electronic device detects a noise signal, it means that the stylus has been affected by the noise. Therefore, it is necessary to adjust the frequency of the stylus and the electronic device so that the adjusted frequency is significantly different from the frequency of the noise. The less similar the frequency of the stylus and the electronic device is to the frequency of the noise, the stronger the anti-interference ability is. The more similar the frequency of the stylus and the electronic device is to the frequency of the noise, the weaker the anti-interference ability is. In order to improve the anti-interference ability and to enable the electronic device and the stylus to adjust the frequency at the same time, the electronic device first sends a data synchronization request to the stylus. The content included in the data synchronization request refers to the above step S102 and will not be repeated here.

[0154] In some embodiments, the data synchronization request also includes the frequency value to be adjusted, that is, after detecting the noise signal, the electronic device can determine the frequency value to be adjusted based on the noise signal. The data synchronization request includes the frequency value to be adjusted, so that after the stylus receives the data synchronization request, it can determine which frequency value to adjust the frequency to.

[0155] In some embodiments, the data synchronization request does not include the frequency value to be adjusted, but the electronic device and the stylus agree in advance on an adjustment method, and the electronic device and the stylus directly adjust the frequency according to the adjustment method.

[0156] Optionally, the adjustment method is: setting a correspondence between the frequency before adjustment and the frequency after adjustment, and adjusting the frequency according to the correspondence. For example, in the correspondence, the frequency 1 before adjustment corresponds to the frequency 2 after adjustment, the frequency 2 before adjustment corresponds to the frequency 3 after adjustment, and the frequency 3 before adjustment corresponds to the frequency 1 after adjustment. When the frequency needs to be adjusted, if the current frequency is frequency 1, it is determined to adjust the frequency to frequency 2; if the current frequency is frequency 2, it is determined to adjust the frequency to frequency 3; if the current frequency is frequency 3, it is determined to adjust the frequency to frequency 1.

[0157] It should be noted that when the electronic device detects a noise signal, sending a data synchronization request to the stylus is an optional step. In some embodiments, the electronic device may send a data synchronization request to the stylus at any time, not just when a noise signal is detected.

[0158] Step S503: the stylus receives a data synchronization request sent by the electronic device and obtains the seventh moment.

[0159] Step S504: the stylus determines a third time difference between the second moment and the ninth moment, and determines the eighth moment as the moment obtained by adding the seventh moment to the third time difference.

[0160] Among them, the ninth moment is the moment at which the delay time is increased by the first moment.

[0161] For example, see Figure 6 When the first moment, the second moment and the delay duration are known, the stylus can calculate the third time difference between the ninth moment and the second moment. The ninth moment of the local clock of the electronic device and the second moment of the local clock of the stylus are the same moment. In order to enable the electronic device and the stylus to adjust the frequency at the same moment, the third time difference can be used as the time difference between the seventh moment and the moment when the stylus adjusts the frequency. Therefore, the moment after adding the seventh moment and the third time difference is determined to be the eighth moment.

[0162] Step S505: the stylus adjusts the frequency of the stylus at the eighth moment.

[0163] Step S506: the electronic device adjusts the frequency of the electronic device at the second moment.

[0164] Since the eighth moment and the second moment are the same moment, the stylus adjusts its frequency at the eighth moment and the electronic device adjusts its frequency at the second moment, which can ensure that the electronic device and the stylus perform frequency hopping at the same moment.

[0165] In some embodiments, when the data synchronization request also includes a frequency value to be adjusted, the electronic device adjusts the frequency of the electronic device to the frequency value at the second moment, and the stylus adjusts the frequency of the stylus to the frequency value at the eighth moment.

[0166] In some embodiments, the electronic device also sends a frequency hopping request to the stylus at the second moment, and the frequency hopping request is used to instruct the stylus to adjust the frequency. Optionally, when the data synchronization request includes a frequency value to be adjusted, the frequency hopping request is used to instruct the stylus to adjust the frequency to the frequency value. However, for the stylus, the stylus adjusts the frequency of the stylus at the eighth moment, and does not need to wait until the frequency hopping request is received before adjusting, that is, the eighth moment when the stylus actually adjusts the frequency has nothing to do with the moment when the frequency hopping request is received.

[0167] Optionally, adjusting the frequency of the electronic device includes: adjusting the downlink frequency of the electronic device.

[0168] According to the method provided by the embodiment of the present disclosure, the electronic device obtains the delay time consumed in the data transmission process between the electronic device and the stylus, and then sends a data synchronization request to the stylus, wherein the data synchronization request includes a first moment, a second moment and a delay time, wherein the first moment is the moment when the electronic device sends the data synchronization request, and the second moment is the moment when the electronic device adjusts the frequency, and the frequency of the electronic device is adjusted at the second moment, and at the same time, the stylus determines an eighth moment according to the received data synchronization request, and adjusts the frequency of the stylus at the eighth moment, and calibrates the frequency adjustment moments of the electronic device and the stylus through the delay time, so that the electronic device and the stylus adjust the frequencies at the same moment, thereby ensuring that the operating frequencies of the electronic device and the stylus are consistent, and reducing the problem that the stylus function cannot be realized due to inconsistent frequencies between the two.

[0169] Figure 7 is a flow chart showing another frequency adjustment method according to an exemplary embodiment, which is performed by an electronic device and a stylus, see Figure 7 , the method comprises the following steps:

[0170] Step S701: The electronic device sends a Delay_Calibration_Req to the stylus pen and uses a local clock to record a timestamp T1.

[0171] Wherein, Delay_Calibration_Req is the delay calibration request mentioned above, and timestamp T1 is the third moment mentioned above.

[0172] Step S702: The stylus receives Delay_Calibration_Req and records the timestamp T2 using the local clock.

[0173] Among them, the timestamp T2 is the fourth moment mentioned above.

[0174] Step S703: The stylus generates and sends a Delay_Calibration_Resp message to the electronic device, and the Delay_Calibration_Resp message includes a timestamp T2.

[0175] Step S704: The electronic device uses the local clock to obtain the timestamp T4 when the Delay_Calibration_Resp message is received.

[0176] Among them, the timestamp T4 is the sixth moment mentioned above.

[0177] Step S705: The stylus sends a Delay_Calibration_Resp_Follow_up message to the electronic device, where the Delay_Calibration_Resp_Follow_up message includes a timestamp T3.

[0178] Among them, the timestamp T3 is the fifth moment mentioned above.

[0179] Step S706: The electronic device calculates the delay duration according to timestamp T1, timestamp T2, timestamp T3 and timestamp T4.

[0180] For example, the delay time is calculated using the following formula:

[0181]

[0182] Among them, Msg delay Indicates the delay duration.

[0183] Step S707: The electronic device records the timestamp T5 using the local clock and initiates an Info_Sync request, wherein the Info_Sync request includes the timestamp T5, the delay duration and the timestamp T7.

[0184] The Info_Sync request is the data synchronization request, the timestamp T5 is the first moment, and the timestamp T7 is the second moment.

[0185] Step S708: The stylus receives the Info_Sync request and uses the local clock to record the timestamp T6.

[0186] Among them, the timestamp T6 is the seventh moment mentioned above.

[0187] Step S709: the electronic device initiates a frequency hopping request Hop Frequency_Req at timestamp T7, and adjusts the frequency at timestamp T7.

[0188] Step S710 , the stylus calculates the time difference Tdiff according to the timestamp T5 , the delay time and the timestamp T7 , calculates the timestamp T8 according to the time difference Tdiff and the timestamp T6 , and adjusts the frequency at the timestamp T8 .

[0189] Where Tdiff is expressed as T7-(T5+Msg delay ), the timestamp T8 is expressed as T6+Tdiff, and the timestamp T8 is the eighth moment mentioned above.
