Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The method for avoiding bluetooth interference provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a method for avoiding bluetooth interference provided in an embodiment of the present application, where the method may include the following steps:
Among them, the target bluetooth device refers to a bluetooth device (such as the device using BPF described above) that is susceptible to interference, such as a bluetooth headset, a bluetooth watch, a bluetooth game pad, etc., and because there is no strong interference source inside the system, the BPF is often used to improve interference due to cost considerations during design. The electronic device may be a smart terminal, such as a smart phone, a tablet computer, or the like.
The electronic equipment can work in frequency bands of B40, B41, B7 and the like, wherein the frequency band of B40 refers to the frequency band with the frequency range of 2300MHz-2400MHz, the frequency band of B41 refers to the frequency band with the frequency range of 2496MHz-2690MHz, and the frequency band of B7 refers to the frequency band with the frequency range of 2500MHz-2570 MHz. For example, the electronic device operates in the B40 frequency band, and the operating channel is a channel in the frequency range of 2350MHz-2400MHz, that is, in this embodiment, the obtained operating frequency band of the electronic device is the B40 frequency band, and the operating channel is a channel in the frequency range of 2350MHz-2400MHz of the B40 frequency band.
102, under the condition that the working frequency band is a target frequency band in at least one preset frequency band and the working channel is a target channel corresponding to the target frequency band, generating a new Bluetooth frequency hopping list according to a preset Bluetooth forbidden frequency band corresponding to the working frequency band, wherein the new Bluetooth frequency hopping list comprises frequency points except the preset Bluetooth forbidden frequency band in the Bluetooth frequency band.
The at least one preset frequency band includes, for example, frequency bands B40, B41, B7, and the acquired operating frequency band of the electronic device is a B40 frequency band, so the B40 frequency band is a target frequency band in the at least one preset frequency band. Meanwhile, under the condition that the electronic equipment works in the B40 frequency band, if the working channel of the electronic equipment is a channel in the frequency range of 2350MHz-2400MHz, it is considered that the electronic equipment working on the working channel interferes with the target bluetooth equipment, therefore, the channel in the frequency range of 2350MHz-2400MHz in the B40 frequency band is taken as the target channel corresponding to the B40 frequency band, and if the electronic equipment works in the target channel, that is, the working channel is the target channel corresponding to the target frequency band B40, in this case, it is considered that the electronic equipment may interfere with the target bluetooth equipment.
When the electronic device works in a target channel in the B40 frequency band, if the target bluetooth device works in the 2402MHz-2430MHz frequency range, the electronic device may possibly generate interference to the target bluetooth device, and in order to avoid that the electronic device working in the target channel in the B40 frequency band has interference to the target bluetooth device, in this embodiment, the frequency band in the 2402MHz-2430MHz frequency range in the bluetooth frequency band is used as a preset bluetooth disabled frequency band corresponding to the B40 frequency band, and in a case that it is determined that the electronic device has interference to the target bluetooth device, the preset bluetooth disabled frequency band (i.e., a channel in a lower frequency range of the bluetooth disabled frequency band) is disabled, and a frequency point in the 2431MHz-2480MHz frequency range is used as a frequency point in a new bluetooth frequency hopping table.
It should be noted that, for example, when the electronic device operates in the B41 frequency band and the operating channel is a target channel corresponding to the B41 frequency band, it is determined that the electronic device operating in the target channel of the B41 frequency band may interfere with the target bluetooth device, where the B41 frequency band is 2496MHz-2690MHz, and the target channel corresponding to the B41 frequency band is, for example, a channel in the 2496MHz-2526MHz frequency band, in this case, the frequency band in the higher frequency range of the bluetooth frequency band is used as a preset bluetooth disable frequency band, for example, the frequency band of 2451MHz-2480MHz is used as a preset bluetooth disable frequency band corresponding to the B41 operating frequency band, that is, the generated new bluetooth frequency hopping table only includes frequency bands of 2402MHz-2450 MHz.
And 103, carrying out Bluetooth data transmission with the target Bluetooth equipment according to the new Bluetooth frequency hopping list.
In the method for avoiding bluetooth interference provided by this embodiment, when a device in communication connection with an electronic device is a target bluetooth device, a working frequency band and a working channel of the electronic device are obtained, and when the working frequency band is a target frequency band in at least one preset frequency band and the working channel is a target channel corresponding to the target frequency band, a new bluetooth frequency hopping list is generated according to a preset bluetooth disabled frequency band corresponding to the working frequency band, where the new bluetooth frequency hopping list includes frequency points in the bluetooth frequency band except for the preset bluetooth disabled frequency band, and bluetooth data transmission is performed with the target bluetooth device according to the new bluetooth frequency hopping list. Because the new Bluetooth frequency hopping list does not include the frequency points in the preset Bluetooth forbidden frequency bands, the frequency points in the preset Bluetooth forbidden frequency bands are prevented from being adopted for Bluetooth data transmission, so that the interference of the electronic equipment on the target Bluetooth equipment is reduced under the condition that the working channel of the electronic equipment is the channel of the preset sub-frequency bands of the preset frequency bands, and the influence on the target Bluetooth equipment is reduced.
It should be noted that, when the working frequency band is a frequency band outside of at least one preset frequency band, or when the working frequency band is a target frequency band in at least one preset frequency band and the working channel is a channel outside of the target channel, bluetooth data transmission is performed with the target bluetooth device according to an original bluetooth frequency hopping table, where the original bluetooth frequency hopping table includes each frequency point in the bluetooth frequency band.
For example, if the electronic device does not operate in a preset frequency band such as B40, B41, B7, etc., it may be determined that the electronic device does not have interference with the target bluetooth device. Or, for example, the electronic device operates in the B40 frequency band, but the operating channel is a channel in the 2300MHz-2349MHz frequency band, the channel in the 2300MHz-2339MHz frequency band is a channel outside the target channel corresponding to the B40 frequency band, where the target channel corresponding to the B40 frequency band is a channel in the 2350MHz-2400MHz frequency band, that is, when the electronic device operates in a channel in a lower frequency range in the B40 frequency band, it may be determined that the electronic device does not interfere with the target bluetooth device, in this case, the bluetooth data transmission is performed with the target bluetooth device according to an original bluetooth frequency hopping table, where the original bluetooth frequency hopping table includes frequency points in the bluetooth frequency band. Namely, the frequency point in the range of 2402MHz-2480MHz is still adopted as the frequency point in the original Bluetooth frequency hopping list, and the frequency point in the range of 2402MHz-2480MHz is still adopted for Bluetooth data transmission.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of another method for avoiding bluetooth interference according to an embodiment of the present application, where the method includes the following steps:
For example, if the device identifier of the device communicatively connected to the electronic device is the identifier of the bluetooth headset, the electronic device may determine that the device is the bluetooth headset according to the device identifier, and the bluetooth headset is the target bluetooth device. If the device identifier of the device in communication connection with the electronic device is the identifier of the bluetooth watch, the electronic device may determine that the device is the bluetooth watch and the bluetooth watch is the target bluetooth device according to the device identifier.
And 203, acquiring the working frequency band and the working channel of the electronic equipment under the condition that the equipment in communication connection with the electronic equipment is the target Bluetooth equipment.
And step 204, acquiring the transmission power of the electronic equipment.
The obtaining of the transmission power of the electronic device may be simultaneous obtaining of the working frequency band and the working channel of the electronic device, or obtaining after obtaining the working frequency band and the working channel of the electronic device, or obtaining before obtaining the working frequency band and the working channel of the electronic device, and this embodiment does not limit the order of obtaining the transmission power of the electronic device.
In this embodiment, a determination condition is added on the basis of the above embodiment, that is, when the operating frequency band is a target frequency band in at least one preset frequency band, the operating channel is a target channel corresponding to the target frequency band, and the transmission power is relatively high (for example, the transmission power is greater than or equal to a first preset threshold), a new bluetooth frequency hopping table is generated according to a preset bluetooth disabled frequency band corresponding to the operating frequency band. If the transmission power of the electronic device is less than the first preset threshold, the bluetooth frequency hopping table is not adjusted even if the conditions of the above embodiment are met, that is, the working frequency band is a target frequency band in at least one preset frequency band and the working channel is a target channel corresponding to the target frequency band.
In the embodiment, through further fine judgment, namely whether the transmitting power of the electronic equipment is more than or equal to a first preset threshold is additionally judged, the adjustment of the Bluetooth frequency hopping table is carried out in a scene where interference is most likely to occur; under other scenes, the frequency hopping list is not adjusted as much as possible, and the phenomenon that the working environment of the Bluetooth is deteriorated due to the fact that available channels are reduced after the frequency hopping list is adjusted is avoided. Therefore, in the present embodiment, by further performing a fine determination, the bluetooth frequency hopping table is adjusted in a scene where interference is most likely to occur.
And step 206, performing Bluetooth data transmission with the target Bluetooth equipment according to the new Bluetooth frequency hopping list.
In the method provided by this embodiment, when the working frequency band is a target frequency band in at least one preset frequency band, the working channel is a target channel corresponding to the target frequency band, and the transmission power is greater than or equal to a first preset threshold, a new bluetooth frequency hopping table is generated according to a preset bluetooth disabled frequency band corresponding to the working frequency band, bluetooth data transmission is performed with a target bluetooth device according to the new bluetooth frequency hopping table, through further fine judgment, adjustment of the bluetooth frequency hopping table in a scene where interference is most likely to occur is achieved, in other scenes, the frequency hopping table is not adjusted as much as possible, and deterioration of a bluetooth working environment due to reduction of usable channels after adjustment of the frequency hopping table is avoided.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of another method for avoiding bluetooth interference according to an embodiment of the present application, where the method includes the following steps:
Before step 301 is performed, the following steps may be included:
a device identification of a device communicatively coupled to an electronic device is obtained.
And judging whether the equipment is the target Bluetooth equipment or not according to the equipment identification.
And step 302, receiving a level value of a signal sent by the target Bluetooth device.
The step may be performed before step 301, or after step 301, or simultaneously with step 301, and the execution order of step 302 is not limited in this embodiment.
And 303, generating a new Bluetooth frequency hopping table according to a preset Bluetooth forbidden frequency band corresponding to the working frequency band under the conditions that the working frequency band is a target frequency band in at least one preset frequency band, the working channel is a target channel corresponding to the target frequency band, and the level value is less than or equal to a second preset threshold value.
In this embodiment, a determination condition is added on the basis of the embodiment shown in fig. 1, that is, when the operating frequency band is a target frequency band in at least one preset frequency band, the operating channel is a target channel corresponding to the target frequency band, and a level value of a signal received by the electronic device and sent by the target bluetooth device is small (for example, the level value is less than or equal to a second preset threshold), a new bluetooth frequency hopping table is generated according to a preset bluetooth disabled frequency band corresponding to the operating frequency band. If the level value is greater than the second preset threshold, the bluetooth frequency hopping table is not adjusted even if the conditions of the embodiment shown in fig. 1 are met, that is, the working frequency band is a target frequency band in at least one preset frequency band and the working channel is a target channel corresponding to the target frequency band.
It should be noted that, if the level value of the signal sent by the target bluetooth device received by the electronic device is greater than or equal to the second preset threshold, that is, the received bluetooth signal is stronger, then the normal frequency hopping table is used to perform bluetooth data transmission (the normal frequency hopping table includes frequency points in the 2402MHz-2480MHz frequency band); if the level value of the received signal is smaller than the second preset threshold value, it indicates that the interference signal is stronger at the moment and has a certain influence on the bluetooth communication, so that the bluetooth frequency hopping meter needs to be adjusted at the moment to generate a new bluetooth frequency hopping meter, and the influence of the strong interference signal on the bluetooth data transmission is avoided.
In the embodiment, through further fine judgment, namely whether the level value of the signal sent by the target bluetooth device and received by the electronic device is less than or equal to a second preset threshold value is additionally judged, the adjustment of the bluetooth frequency hopping table is realized in a scene where interference is most likely to occur; under other scenes, the frequency hopping list is not adjusted as much as possible, and the phenomenon that the working environment of the Bluetooth is deteriorated due to the fact that available channels are reduced after the frequency hopping list is adjusted is avoided. Therefore, in the present embodiment, by further performing a fine determination, the bluetooth frequency hopping table is adjusted in a scene where interference is most likely to occur.
And step 304, carrying out Bluetooth data transmission with the target Bluetooth equipment according to the new Bluetooth frequency hopping list.
In the method provided by this embodiment, under the condition that the operating frequency band is a target frequency band in at least one preset frequency band, the operating channel is a target channel corresponding to the target frequency band, and the level value is less than or equal to the second preset threshold, a new bluetooth frequency hopping table is generated according to a preset bluetooth disabled frequency band corresponding to the operating frequency band, bluetooth data transmission is performed with the target bluetooth device according to the new bluetooth frequency hopping table, through further fine judgment, adjustment of the bluetooth frequency hopping table in a scene where interference is most likely to occur is achieved, in other scenes, the frequency hopping table is not adjusted as much as possible, and deterioration of a bluetooth operating environment due to reduction of usable channels after adjustment of the frequency hopping table is avoided.
