[0095] It should be noted that the scenario diagram of the device display system shown in FIG. 1 is merely an example, and the device display system and scenario described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, as the device display system evolves and new service scenarios appear, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0096] As shown in FIG. 2, it is a flow diagram of one embodiment of the device display method in the embodiments of the present application. The device display method can include the following steps S201-S203, which are as follows:

[0097] Step S201, obtaining a first signal strength value of a first Bluetooth device at a first scanning time and a second signal strength value of the first Bluetooth device at a second scanning time; the first scanning time and the second scanning time are two different scanning times in a same scanning period.

[0098] In a specific embodiment, the terminal device scans the surrounding Bluetooth devices according to a scanning period. A scanning period includes an inquiry process and a remote name request (RNR) process. The first scanning time and the second scanning time are two different scanning times in a same scanning period, for example, the first scanning time is 11:15:48 and the second scanning time is 11:15:50.

[0099] Further, the first Bluetooth device is a Bluetooth device scanned by the terminal device at the first scanning time and the second scanning time. The first signal strength value is a Bluetooth received signal strength indication (RSSI) of the first Bluetooth device scanned by the terminal device at the first scanning time. The second signal strength value is an RSSI value of the first Bluetooth device scanned by the terminal device at the second scanning time.

[0100] Step S202, determining a device display time of the first device information corresponding to the first Bluetooth device in the device list based on the first signal strength value and the second signal strength value.

[0101] The first device information in the embodiment is information related to the first Bluetooth device. For example, the first device information can be a device identifier of the first Bluetooth device, the first device information can also be a device name of the first Bluetooth device, and the first device information can also be a device icon of the first Bluetooth device. The embodiment is not limited in this regard. The device display time is a display time period of the first device information corresponding to the first Bluetooth device in the device list. For example, the second scan time is 11:15:50, the display time of the first device information in the device list is 11:15:50-11:15:50+6.4 seconds, or the display time of the first device information in the device list is 11:15:50-11:15:50+12.8 seconds.

[0102] In an embodiment, the step of determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the first signal strength value and the second signal strength value includes: comparing the first signal strength value with the second signal strength value; if the second signal strength value is greater than or equal to the first signal strength value, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scan time and a preset first display duration; if the second signal strength value is less than the first signal strength value, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scan time and a preset second display duration; and the second display duration is less than the first display duration. For example, the first display duration is 12.8 seconds, the second display duration is 5.6 seconds, if the second signal strength value is greater than or equal to the first signal strength value, the device display time of the first device information in the device list is determined as the second scan time-the second scan time+12.8 seconds; if the second signal strength value is less than the first signal strength value, the device display time of the first device information in the device list is determined as the second scan time-the second scan time+6.4 seconds. Thus, the display time of the device information corresponding to the Bluetooth device in the device list can be adjusted according to the signal strength change of the Bluetooth device, so that the device information corresponding to the Bluetooth device is not displayed in the device list when the Bluetooth device is in a shutdown or hibernation state, or the Bluetooth device has moved away from the terminal device.

[0103] In another specific embodiment, the step of determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the first signal strength value and the second signal strength value comprises: comparing the first signal strength value with the second signal strength value; if the second signal strength value is greater than or equal to the first signal strength value, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scanning time and the first display duration; if the second signal strength value is less than the first signal strength value and the first signal strength difference value is greater than the first strength threshold, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scanning time and the second display duration; if the second signal strength value is less than the first signal strength value and the first signal strength difference value is less than or equal to the first strength threshold, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scanning time and the first display duration. The first signal strength difference value is the absolute value of the difference between the first signal strength value and the second signal strength value. For example, the first display duration is 12.8s, the second display duration is 5.6s, if the second signal strength value is greater than or equal to the first signal strength value, the device display time of the first device information in the device list is determined as the second scanning time~the second scanning time+12.8s; if the second signal strength value is less than the first signal strength value and the first signal strength difference value is greater than the first strength threshold, the device display time of the first device information in the device list is determined as the second scanning time~the second scanning time+6.4s; if the second signal strength value is less than the first signal strength value and the first signal strength difference value is less than or equal to the first strength threshold, the device display time of the first device information in the device list is determined as the second scanning time~the second scanning time+12.8s.

[0104] In step S203, if the display time of the first device information in the device list exceeds the device display time, the first device information is deleted from the device list.

[0105] In the embodiment, the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the first signal strength value and the second signal strength value, and if the display time of the first device information in the device list exceeds the device display time, the first device information is deleted from the device list. The display time of the device information in the device list can be adjusted according to the change of the signal strength value of the Bluetooth device, and the device information is deleted from the device list when the display time exceeds the device display time. The device information corresponding to the Bluetooth device in the sleep or shutdown state can disappear in the device list as soon as possible, and the problem of pairing connection failure caused by the user clicking the Bluetooth device in the sleep or shutdown state in the device list can be solved.

[0106] In a specific implementation, with reference to FIG. 3, the step of determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the first signal strength value and the second signal strength value in the step S202 can include steps S301-S303, and the details are as follows:

[0107] In step S301, the first signal strength value is compared with the second signal strength value.

[0108] In step S302, if the second signal strength value is greater than or equal to the first signal strength value, the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the second scanning time and the preset first display duration.

[0109] The first display duration in the embodiment can be set according to actual needs. For example, the first display duration is set to 12.8 seconds. If the second signal strength value is greater than or equal to the first signal strength value, it indicates that the first Bluetooth device is not far away from the terminal device, and the first Bluetooth device is not in sleep or shutdown. Then, the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the second scanning time and the preset first display duration. For example, the first display duration is set to 12.8 seconds. If the second signal strength value is greater than or equal to the first signal strength value, the device display time of the first device information in the device list is the second scanning time-second scanning time+12.8 seconds.

[0110] In step S303, if the second signal strength value is less than the first signal strength value, the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the first signal strength difference value. The first signal strength difference value is the absolute value of the difference between the first signal strength value and the second signal strength value.

[0111] In the embodiment, the first signal strength difference value is the absolute value of the difference between the first signal strength value and the second signal strength value. If the second signal strength value is less than the first signal strength value, that is, the RSSI value of the first Bluetooth device is decreasing, the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the decreasing amplitude of the RSSI value of the first Bluetooth device.

[0112] In a specific embodiment, the step of determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the first signal strength difference value includes: comparing the first signal strength difference value with a preset first strength threshold value; if the first signal strength difference value is greater than the first strength threshold value, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scanning time and a preset second display duration; if the first signal strength difference value is less than or equal to the first strength threshold value, determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the second scanning time and the first display duration.

[0113] The first strength threshold value is a threshold value preset for measuring the reduction amplitude of the RSSI value of the first Bluetooth device. If the first signal strength difference value is greater than the first strength threshold value, it indicates that the reduction amplitude of the RSSI value of the first Bluetooth device is relatively large, and the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the second scanning time and the preset second display duration. If the first signal strength difference value is less than or equal to the first strength threshold value, it indicates that the reduction amplitude of the RSSI value of the first Bluetooth device is relatively small, and the device display time of the first device information corresponding to the first Bluetooth device in the device list is determined based on the second scanning time and the first display duration.

[0114] Further, the second display duration can be set according to actual needs, but the second display duration is less than the first display duration. For example, the first display duration is 12.8 seconds, and the second display duration is 6.4 seconds. If the first signal strength difference value is greater than the first strength threshold value, the device display time of the first device information in the device list is determined as the second scanning time~the second scanning time+6.4 seconds. If the first signal strength difference value is less than or equal to the first strength threshold value, the device display time of the first device information in the device list is determined as the second scanning time~the second scanning time+12.8 seconds.

[0115] In a specific implementation, referring to FIG. 4, after the step S202 of determining the device display time of the first device information corresponding to the first Bluetooth device in the device list based on the first signal strength value and the second signal strength value, the steps S401-S402 can be further included, which are specifically as follows:

[0116] Step S401, obtaining a third signal strength value of the first Bluetooth device at a third scanning time; the third scanning time is a scanning time different from the first scanning time and the second scanning time in the same scanning period.

[0117] The third scanning time in the embodiment is a scanning time different from the first scanning time and the second scanning time in the same scanning cycle, for example, the first scanning time is 11:15:48, the second scanning time is 11:15:50, and the second scanning time is 11:15:52. The third signal strength value is the RSSI value of the first Bluetooth device scanned by the terminal device at the third scanning time.

[0118] In step S402, the device display time of the first device information in the device list is updated based on the first signal strength value, the second signal strength value, and the third signal strength value.

[0119] In an embodiment, updating the device display time of the first device information in the device list based on the first signal strength value, the second signal strength value, and the third signal strength value can include the following steps:

[0120] (1) Comparing the third signal strength value with the second signal strength value.

[0121] (2) If the third signal strength value is greater than or equal to the second signal strength value and the second signal strength value is greater than or equal to the first signal strength value, updating the device display time of the first device information in the device list based on the third scanning time and the preset first display duration.

[0122] In the embodiment, if the third signal strength value is greater than or equal to the second signal strength value and the second signal strength value is greater than or equal to the first signal strength value, it indicates that the RSSI value of the first Bluetooth device is continuously increasing. Therefore, the device display time of the first device information in the device list is updated based on the third scanning time and the first display duration, so that the Bluetooth device that can normally be connected can be displayed in the device list without being displayed due to timeout. For example, if the first display duration is 12.8 seconds, and the third signal strength value is greater than or equal to the second signal strength value and the second signal strength value is greater than or equal to the first signal strength value, the device display time of the first device information in the device list is determined as the third scanning time~the third scanning time+12.8 seconds.

[0123] (3) If the third signal strength value is less than the second signal strength value and the second signal strength value is greater than or equal to the first signal strength value, updating the device display time of the first device information in the device list based on the second signal strength difference value.

[0124] In the embodiment, the second signal strength difference value is the absolute value of the difference between the third signal strength value and the second signal strength value. If the third signal strength value is less than the second signal strength value and the second signal strength value is greater than or equal to the first signal strength value, the device display time of the first device information in the device list is updated based on the decreasing amplitude of the third signal strength value.

[0125] In a specific embodiment, the step of updating the device display time of the first device information in the device list based on the second signal strength difference value specifically comprises: if the second signal strength difference value is greater than a preset first strength threshold, updating the device display time of the first device information in the device list based on the third scanning time and a preset second display duration; if the second signal strength difference value is less than or equal to the first strength threshold, updating the device display time of the first device information in the device list based on the third scanning time and a first display duration. The second display duration is less than the first display duration. For example, the first display duration is 12.8 seconds, and the second display duration is 6.4 seconds. If the second signal strength difference value is greater than the preset first strength threshold, i.e., the third signal strength value is reduced more than the second signal strength value, the device display time of the first device information in the device list is determined to be the third scanning time~the third scanning time+6.4 seconds. If the second signal strength difference value is less than or equal to the first strength threshold, i.e., the third signal strength value is reduced less than the second signal strength value, the device display time of the first device information in the device list is determined to be the third scanning time~the third scanning time+12.8 seconds.

[0126] (4) If the third signal strength value is less than the second signal strength value and the second signal strength value is less than the first signal strength value, updating the device display time of the first device information in the device list based on the first signal strength difference value and the second signal strength difference value.

[0127] In the embodiment, the first signal strength difference value is the absolute value of the difference between the first signal strength value and the second signal strength value. If the RSSI value of the first Bluetooth device is reduced twice in succession, the device display time of the first device information in the device list is updated based on the reduction amplitude of the two times.

[0128] In a specific embodiment, the step of updating the device display time of the first device information in the device list based on the first signal strength difference value and the second signal strength difference value specifically comprises: if the second signal strength difference value is less than or equal to the first strength threshold and / or the first signal strength difference value is less than or equal to the first strength threshold, updating the device display time of the first device information in the device list based on the third scanning time and the second display duration; if the second signal strength difference value is greater than the first strength threshold and the first signal strength difference value is greater than the first strength threshold, deleting the first device information from the device list. For example, if the second signal strength difference value is less than or equal to the first strength threshold and / or the first signal strength difference value is less than or equal to the first strength threshold, the device display time of the first device information in the device list is determined to be the third scanning time~the third scanning time+6.4 seconds.

[0129] The embodiment scans the first Bluetooth device multiple times in the same scanning period, and directly deletes the first device information from the device list when the RSSI value of the first Bluetooth device continuously decreases and the decreasing amplitude exceeds the first intensity threshold. The device information corresponding to the Bluetooth device in the sleep state or the shutdown state or the Bluetooth device far away from the terminal device can be directly deleted from the device list, thereby avoiding the problem of connection failure caused by the Bluetooth device in the sleep state or the shutdown state being displayed in the device list.

[0130] In a specific implementation, with reference to FIG. 5, the device display method further includes steps S501-S504, and the details are as follows.

[0131] In step S501, it is judged whether the first device information is stored locally.

[0132] In a specific embodiment, the terminal device sends a remote name request (RNR) to multiple Bluetooth devices with the highest signal intensity in each scanning period, to obtain the device names corresponding to the multiple Bluetooth devices, and saves the Bluetooth devices with the obtained device names to the local device.

[0133] To determine whether the first Bluetooth device is a Bluetooth device with the obtained device name, the embodiment first judges whether the first device information is stored locally. If the first device information is stored locally, it indicates that the first Bluetooth device is a Bluetooth device with the obtained device name. Otherwise, if the first device information is not stored locally, it indicates that the first Bluetooth device is a Bluetooth device without the obtained device name.

[0134] In step S502, if the first device information is not stored locally, the first signal intensity value is compared with a preset second intensity threshold.

[0135] The second intensity threshold is a preset intensity threshold for measuring whether the first signal intensity value meets the requirement. The second intensity threshold can be set according to actual needs. For example, the second intensity threshold can be set to -60 db. If the first device information is not stored locally, that is, the first Bluetooth device is a Bluetooth device without the obtained device name, the first signal intensity value is compared with the preset second intensity threshold.

[0136] In step S503, if the first signal intensity value is greater than or equal to the second intensity threshold and the first Bluetooth device is not in the remote name request queue, the first Bluetooth device is added to the remote name request queue.

[0137] The Bluetooth device requiring to obtain the device name is stored in the remote name request queue. In the embodiment, if the first signal strength value is greater than or equal to the second strength threshold value and the first Bluetooth device is not in the remote name request queue, the first Bluetooth device is added to the remote name request queue. For example, the second strength threshold value is -60db, and if the first signal strength value is -50db and the first Bluetooth device is not in the remote name request queue, the first Bluetooth device is added to the remote name request queue.

[0138] In step S504, if the first signal strength value is less than the second strength threshold value and the first Bluetooth device is in the remote name request queue, the first Bluetooth device is deleted from the remote name request queue.

[0139] In the embodiment, if the first signal strength value is less than the second strength threshold value and the first Bluetooth device is in the remote name request queue, the first Bluetooth device is deleted from the remote name request queue. In this way, the Bluetooth device with weak signal strength value can be deleted from the remote name request queue, and the time of the RNR process is shortened. For example, the second strength threshold value is -60db, and if the first signal strength value is -70db and the first Bluetooth device is in the remote name request queue, the first Bluetooth device is deleted from the remote name request queue.

[0140] In a specific embodiment, after the second signal strength value is obtained, the following steps are included: judging whether the first device information is stored locally, if the first device information is not stored locally, comparing the second signal strength value with the preset second strength threshold value; if the second signal strength value is greater than or equal to the second strength threshold value and the first Bluetooth device is not in the remote name request queue, adding the first Bluetooth device to the remote name request queue; and if the second signal strength value is less than the second strength threshold value and the first Bluetooth device is in the remote name request queue, deleting the first Bluetooth device from the remote name request queue.

[0141] In a specific embodiment, after the third signal strength value is obtained, the following steps are included: judging whether the first device information is stored locally, if the first device information is not stored locally, comparing the third signal strength value with the preset second strength threshold value; if the third signal strength value is greater than or equal to the second strength threshold value and the first Bluetooth device is not in the remote name request queue, adding the first Bluetooth device to the remote name request queue; and if the third signal strength value is less than the second strength threshold value and the first Bluetooth device is in the remote name request queue, deleting the first Bluetooth device from the remote name request queue.

[0142] In a specific implementation, the device display method further includes: determining a first target Bluetooth device from the remote name request queue based on the signal strength values of the plurality of candidate Bluetooth devices in the remote name request queue; and sending a remote name request to the first target Bluetooth device to obtain the device name of the first target Bluetooth device.

[0143] The first target Bluetooth device is a Bluetooth device with a high signal strength value in the remote name request queue, for example, the first target Bluetooth device is three Bluetooth devices with high signal strength values in the remote name request queue. In this embodiment, the plurality of candidate Bluetooth devices in the remote name request queue are filtered based on the signal strength values, and the remote name request is sent to the first target Bluetooth device filtered, so that the time of the RNR process in each scanning period can be shortened.

[0144] In a specific implementation, after determining the first target Bluetooth device from the remote name request queue based on the signal strength values of the plurality of candidate Bluetooth devices in the remote name request queue, the method further includes: saving second device information corresponding to the first target Bluetooth device to the local device, so that the device information saved in the local device is all device information of the Bluetooth device with the acquired device name. Whether the Bluetooth device has acquired the device name can be determined by judging whether the device information is saved in the local device.

[0145] In a specific implementation, before saving the second device information corresponding to the first target Bluetooth device to the local device, the method further includes: judging whether a storage space occupied by third device information corresponding to a plurality of second target Bluetooth devices in the local device is greater than a preset threshold; if the storage space occupied by the third device information is greater than the preset threshold, determining a third target Bluetooth device from the plurality of second target Bluetooth devices based on a saving time of the third device information in the local device; and deleting device information of the third target Bluetooth device from the local device.

[0146] The plurality of second target Bluetooth devices are Bluetooth devices with acquired device names stored in the local device, and the third target Bluetooth device is a Bluetooth device with a high saving time from high to low in the plurality of second target Bluetooth devices. If the storage space occupied by the third device information is greater than the preset threshold, the device information corresponding to the Bluetooth device with the longest saving time is deleted from the local device, so that the redundant storage space can be released for storing the second device information corresponding to the first target Bluetooth device.
