[0008] In a second aspect of the present application, a Bluetooth networking device is provided, the device comprising:
[0009] The information acquisition unit is used to obtain the associated device information list set S=(S1, S2, ..., S i , …, S n ); i = 1, 2, ..., n; wherein n is the number of associated devices of the device to be networked; S i is the device information list of the i-th associated device of the device to be networked; S i =(SB i , SX i , SG i );SB i SX is the device identifier of the i-th associated device of the device to be networked; i is the connection signal strength between the i-th associated device of the device to be networked and the device to be networked; SG i is the connection list corresponding to the i-th associated device of the device to be networked; SG i =(SG i，1 , SG i，2 ,…,SG i，a ,…,SG i，f(i) ); a = 1, 2, ..., f(i); f(i) is the number of associated devices corresponding to the i-th associated device of the device to be networked; SG i，aThe device identifier of the a-th associated device corresponding to the i-th associated device of the device to be networked; the Bluetooth connection mode corresponding to the associated device is bidirectional interconnection through the write connection mode and the notify connection mode;

[0014] This application has at least the following beneficial effects:
[0015] The Bluetooth networking method provided in the present application, when the device to be networked currently turns on Bluetooth and connects with other devices that have already turned on Bluetooth, obtains a list set S of associated device information of the device to be networked. Here, each associated device included in S is a device that has been connected to the device to be networked via Bluetooth, and due to a series of factors such as the distance between devices and the configuration of the devices themselves, some devices have not established a Bluetooth connection with the device to be networked, and each associated device included in S also has its own corresponding associated device. And in the present application, the Bluetooth connection mode corresponding to the associated device is a bidirectional interconnection through a write connection mode and a notify connection mode. That is, on the basis of the bidirectional establishment of the write connection mode, in order to improve the stability of the Bluetooth connection, a bidirectional notify connection mode is established. Furthermore, if SG i，a =SB j , it means that the jth associated device of the device to be networked and the ath associated device of the ith associated device of the device to be networked are the same device. And in this embodiment, SX j is less than the preset connection signal strength threshold, that is, the connection signal strength between the device to be networked and its corresponding j-th associated device is less than the preset connection signal strength threshold, and SGX i，a >SX j , that is, the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device is greater than the connection signal strength between the device to be networked and the commonly connected device, which means that the stability of the Bluetooth connection between the commonly connected device and the i-th associated device of the device to be networked is higher, and the stability of the Bluetooth connection between the commonly connected device and the device to be networked is not very high. At this time, the signal strength difference between the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device and the connection signal strength between the device to be networked and the commonly connected device is obtained. The larger the signal strength difference is, the higher the stability of the Bluetooth connection between the commonly connected device and the i-th associated device of the device to be networked is than the stability of the Bluetooth connection between the commonly connected device and the device to be networked. If SC i，a，jGreater than the first signal difference threshold, that is, the difference in signal strength between the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device and the connection signal strength between the device to be networked and the commonly connected device is large. At this time, disconnect any write connection mode between the device to be networked and the corresponding j-th associated device. The present application disconnects any write connection mode with weaker connection strength with the commonly connected device when the device to be networked and its associated device have a commonly connected device. On the one hand, it saves the Bluetooth resource occupation of the corresponding device, and on the other hand, it can achieve relatively stable Bluetooth networking and relatively stable data transmission. And because only any write connection mode is disconnected, there is also a two-way data transmission path. When problems occur in other paths, this path can also be used for data transmission. The stability of data transmission is further guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] During the flight, there is no Internet network and traditional Internet applications cannot be used normally. In this case, instant communication methods such as Bluetooth can realize communication between devices without relying on the Internet, which can change this situation and improve the flight experience of passengers. However, due to the complex situation on the plane, in the process of Bluetooth networking between multiple devices on the plane, relying only on the conventional write connection method, the connection is not stable enough.
[0023] Therefore, please refer to Figure 1 As shown, an embodiment of the present application provides a Bluetooth networking method, the method comprising:
[0024] S100, in response to receiving a Bluetooth access signal from a device to be networked, obtaining a list of associated device information S=(S1, S2, . . . , S i , …, S n ); i = 1, 2, ..., n; wherein n is the number of associated devices of the device to be networked; S i is the device information list of the i-th associated device of the device to be networked; S i =(SB i , SX i , SG i);SB i SX is the device identifier of the i-th associated device of the device to be networked; i is the connection signal strength between the i-th associated device of the device to be networked and the device to be networked; SG i is the connection list corresponding to the i-th associated device of the device to be networked; SG i =(SG i，1 , SG i，2 ,…,SG i，a ,…,SG i，f(i) ); a = 1, 2, ..., f(i); f(i) is the number of associated devices corresponding to the i-th associated device of the device to be networked; SG i，a It is the device identifier of the ath associated device corresponding to the ith associated device of the device to be networked; the Bluetooth connection mode corresponding to the associated device is bidirectional interconnection through the write connection mode and the notify connection mode.
[0025] Specifically, in the onboard scenario, the distance between devices is relatively close. In the absence of the Internet, information is exchanged through near-field communication methods such as Bluetooth. As each user controls the Bluetooth switch of the device and the user's position changes, the networking situation changes at any time. In this embodiment, when the device to be networked currently turns on Bluetooth, it connects with other devices that have turned on Bluetooth, and obtains the associated device information list set S of the device to be networked. Here, each associated device included in S is a device that has been connected to the device to be networked through Bluetooth, and due to a series of factors such as the distance between devices and the configuration of the device itself, some devices have not established a Bluetooth connection with the device to be networked, and each associated device included in S also has its own corresponding associated device.
[0026] It should be noted that the Bluetooth connection signal strength between devices can be obtained. Here, the Bluetooth connection signal strength may be related to factors such as the environment, the distance between devices, the configuration of the device itself, the personalized settings of the device, and the power of the device.
[0027] In addition, the Bluetooth connection mode corresponding to the associated devices in this embodiment (between the device to be networked and its corresponding associated device, and between the associated device of the device to be networked and its corresponding associated device) is bidirectional interconnection through the write connection mode and the notify connection mode.
[0028] In Bluetooth connection, the write connection mode usually refers to the process of writing data from one device (usually called "host" or "client") to another device (usually called "slave" or "server") through the interface or function provided by the Bluetooth protocol stack. This process involves multiple steps such as pairing, connection, and data transmission of Bluetooth devices. That is, the write connection mode only supports one-way data transmission, that is, after device A as the data sender and device B as the device receiver are connected through the write connection mode, device A can send data to device B, but device B cannot send data to device A. In related technologies, if device B sends data to device A, it can be achieved by connecting device B as the data sender and device A as the device receiver through the write connection mode.
[0029] In this embodiment, the Bluetooth connection mode corresponding to the associated device is bidirectional interconnection through a write connection mode and a notify connection mode. That is, on the basis of bidirectionally establishing a write connection mode, in order to improve the stability of the Bluetooth connection, a bidirectional notify connection mode is also established.
[0030] Among them, the notify connection mode is a data transmission mechanism based on Bluetooth Low Energy (BLE) technology. Notify is a one-way communication mechanism in BLE that allows the slave device to automatically send a notification to the master device when there is new data. This mechanism does not require a request from the master device, and the slave device can decide independently when to send data.
[0031] S200, if SG i，a =SB j , and SX j Less than the preset connection signal strength threshold, and SGX i，a >SX j , then get SC i，a，j =SGX i，a -SX j ; Among them, SGX i，a For SG i，a The corresponding device and S i The connection signal strength between the corresponding devices; SB j SX is the device identifier of the jth associated device of the device to be networked; j is the connection signal strength between the j-th associated device of the device to be networked and the device to be networked; j=1, 2, ..., n.
[0032] Specifically, if SG i，a =SB j , it means that the jth associated device of the device to be networked and the ath associated device of the ith associated device of the device to be networked are the same device. (hereinafter referred to as the commonly connected device) and in this embodiment, SXj is less than the preset connection signal strength threshold, that is, the connection signal strength between the device to be networked and its corresponding j-th associated device is less than the preset connection signal strength threshold, and SGX i，a >SX j , that is, if the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device is greater than the connection signal strength between the device to be networked and the commonly connected device, it means that the stability of the Bluetooth connection between the commonly connected device and the i-th associated device of the device to be networked is higher, and the stability of the Bluetooth connection between the commonly connected device and the device to be networked is not too high. At this time, the signal strength difference between the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device and the connection signal strength between the device to be networked and the commonly connected device is obtained. The larger the signal strength difference is, the higher the stability of the Bluetooth connection between the commonly connected device and the i-th associated device of the device to be networked is than the stability of the Bluetooth connection between the commonly connected device and the device to be networked.
[0033] S300, if SC i，a，j If the signal difference is greater than the first signal difference threshold, any write connection between the device to be networked and the corresponding j-th associated device is disconnected.
[0034] Specifically, if SC i，a，j is greater than a first signal difference threshold, that is, the signal strength difference between the connection signal strength of the i-th associated device of the device to be networked and the commonly connected device and the signal strength between the device to be networked and the commonly connected device is large. At this time, any write connection mode between the device to be networked and the corresponding j-th associated device is disconnected. Any write connection mode here refers to a write connection mode in which the device to be networked is the data sender and the device to be networked and the corresponding j-th associated device are the data receivers, or a write connection mode in which the device to be networked is the data receiver and the device to be networked and the corresponding j-th associated device are the data sender.
[0035] In this embodiment, any write connection mode between the device to be networked and the corresponding j-th associated device is disconnected, that is, the device to be networked and the corresponding j-th associated device can only maintain one channel for data transmission between each other. At this time, the Bluetooth resource occupation of the device to be networked and its corresponding j-th associated device is saved, and it can maintain a two-way data transmission channel (one-way write connection mode and its corresponding notify connection mode). In order to improve the stability of data transmission, when data is transmitted between the device to be networked and the j-th associated device (jointly connected device), it can be forwarded through the i-th associated device of the device to be networked. Since the connection signal strength between the i-th associated device of the device to be networked and the jointly connected device is greater, it is more stable to forward data transmission through it.
[0036] Thus, by processing each associated device of the device to be networked and the associated devices of each associated device according to the above steps, a relatively stable Bluetooth network and relatively stable data transmission can be achieved. And because the device to be networked and the corresponding j-th associated device also have a bidirectional data transmission path, when other paths have problems, this path can also be used for data transmission.
[0037] In summary, in this embodiment, when the device to be networked and its associated device have a common connection device, any write connection mode with a weaker connection strength with the common connection device is disconnected, which saves the Bluetooth resource occupation of the corresponding device on the one hand, and can achieve a relatively stable Bluetooth networking and data transmission on the other hand. And because only any write connection mode is disconnected, there is also a two-way data transmission path, which can also be used for data transmission when other paths have problems.
[0038] In an exemplary embodiment of the present application, after step S200, the method further includes:
[0039] S400, if SC i，a，j If the signal difference is less than or equal to the first signal difference threshold, the number of devices DN and S that are currently interconnected by the write connection mode and the notify connection mode are obtained. i The number of devices that are currently interconnected via write connection and notify connection in the corresponding device. i .
[0040] S500, if DN>SN i , then disconnect any write connection between the device to be networked and the corresponding j-th associated device.
[0041] In this embodiment, if SC i，a，jis less than or equal to the first signal difference threshold, it means that the signal strength difference between the connection signal strength between the i-th associated device of the to-be-networked device and the commonly connected device and the signal strength difference between the to-be-networked device and the commonly connected device is small, at this time, the number of devices connected to the to-be-networked device and S i The number of devices connected to the corresponding device. Disconnect any write connection mode from devices with a large number of device connections. The more devices are connected, the worse the connection signal strength between the connected devices may be. Therefore, when the difference in signal strength between the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device and the connection signal strength between the device to be networked and the commonly connected device is small, disconnect any write connection mode from devices with a large number of device connections. Ensure the stability of the Bluetooth connection of each device as much as possible and improve the stability of the overall Bluetooth networking system.
[0042] In an exemplary embodiment of the present application, after step S400, the method further includes:
[0043] S600, if DN<SN i , then disconnect S i Corresponding equipment and SG i，a Any write connection method between corresponding devices.
[0044] In this embodiment, if SC i，a，j is less than or equal to the first signal difference threshold, it means that the signal strength difference between the connection signal strength between the i-th associated device of the to-be-networked device and the commonly connected device and the connection signal strength between the to-be-networked device and the commonly connected device is small. i , that is, S i The number of devices connected to the corresponding device is large. In order to ensure the overall stability of the Bluetooth networking system, disconnect S i Corresponding equipment and SG i，a Any write connection method between corresponding devices. Try to ensure S i The stability of the Bluetooth connection between the corresponding device and each device.
[0045] In an exemplary embodiment of the present application, after step S100, the method further includes:
[0046] S700, if SG i，a =SB j , and SX j Equal to or greater than the preset connection signal strength threshold, and SGX i，a >SX j , then get SC i，a，j =SGX i，a -SX j.
[0047] S800, if SC i，a，j If the signal difference is greater than a second signal difference threshold, any write connection between the device to be networked and the corresponding j-th associated device is disconnected; wherein the second signal difference threshold is greater than the first signal difference threshold.
[0048] In this embodiment, if SG i，a =SB j , it means that the jth associated device of the device to be networked and the ath associated device of the ith associated device of the device to be networked are the same device. (hereinafter referred to as the commonly connected device) and in this embodiment, SX j Equal to or greater than the preset connection signal strength threshold, that is, the connection signal strength between the device to be networked and its corresponding j-th associated device is equal to or greater than the preset connection signal strength threshold. At this time, SGX i，a >SX j , that is, the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device is greater than the connection signal strength between the device to be networked and the commonly connected device, which means that the stability of the Bluetooth connection between the commonly connected device and the i-th associated device of the device to be networked is higher, but because the stability of the Bluetooth connection between the commonly connected device and the device to be networked is relatively high, if the signal strength difference between the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device and the connection signal strength between the device to be networked and the commonly connected device is relatively large (the second signal difference threshold is greater than the above-mentioned first signal difference threshold). Also disconnect any write connection mode between the device to be networked and the corresponding j-th associated device. That is, the stability between the device to be networked and the commonly connected device is relatively high, but the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device is much higher than the connection signal strength between the device to be networked and the commonly connected device, and also disconnect any write connection mode between the device to be networked and the corresponding j-th associated device. A more stable Bluetooth networking system can be obtained.
[0049] In addition, after step S700, the method further includes:
[0050] S900, if SC i，a，j If the signal difference is less than the first signal difference threshold, the number of devices DN and S that are currently interconnected by the write connection mode and the notify connection mode are obtained. i The number of devices that are currently interconnected via write connection and notify connection in the corresponding device. i , and jump to step S500.
[0051] That is, the stability between the device to be networked and the commonly connected device is relatively high, and the connection signal strength between the i-th associated device of the device to be networked and the commonly connected device is slightly greater than the connection signal strength between the device to be networked and the commonly connected device. i The number of device connections of the corresponding device is determined. The same as the above embodiment, which will not be repeated here.
[0052] In an exemplary embodiment of the present application, the device to be networked and S i The corresponding notify connection mode between the devices includes a first notify connection mode and a second notify connection mode;
[0053] The device to be networked performs the following steps to communicate with S i The corresponding device establishes the first notify connection mode:
[0054] S111, get S i The Bluetooth broadcast signal sent by the corresponding device;
[0055] S112, if S i If the Bluetooth broadcast signal sent by the corresponding device is verified, it will be sent to S i The corresponding device initiates a connection request;
[0056] S113, in response to the connection request being passed, establishing a first write connection mode; wherein the first write connection mode is used for the networked device to send a write request to S i The corresponding device sends data;
[0057] S114, Subscribe to S i The corresponding device's notify notification is used to establish a first notify connection mode; wherein the first notify connection mode is used for the networked device to receive S when there is no second write connection mode. i The corresponding device sends data; the second write connection mode is used for S i The corresponding device sends data to the device to be networked;
[0058] S i The corresponding device establishes a second notify connection mode with the device to be networked by performing the following steps:
[0059] S121, obtaining a Bluetooth broadcast signal sent by the device to be networked;
[0060] S122, if the Bluetooth broadcast signal sent by the device to be networked is verified, a connection request is initiated to the device to be networked;
[0061] S123, in response to the connection request being approved, establishing a second write connection mode;
[0062] S124, subscribe to the notify notification of the device to be networked to establish a second notify connection mode; wherein the second notify connection mode is used for S i When there is no first write connection mode, the corresponding device receives data sent by the device to be networked.
[0063] The above-mentioned establishment method of the notify connection mode in this embodiment is applicable to any two devices bidirectionally interconnected by the write connection mode and the notify connection mode.
[0064] In the above manner, a two-way four-channel Bluetooth connection is established between devices.
[0065] Please refer to Figure 2 As shown, an embodiment of the present application provides a Bluetooth networking device 100, the device comprising:
[0066] The information acquisition unit 110 is used to obtain the associated device information list set S=(S1, S2, ..., S i , …, S n ); i = 1, 2, ..., n; wherein n is the number of associated devices of the device to be networked; S i is the device information list of the i-th associated device of the device to be networked; S i =(SB i , SX i , SG i );SB i SX is the device identifier of the i-th associated device of the device to be networked; i is the connection signal strength between the i-th associated device of the device to be networked and the device to be networked; SG i is the connection list corresponding to the i-th associated device of the device to be networked; SG i =(SG i，1 , SG i，2 ,…,SG i，a ,…,SG i，f(i) ); a = 1, 2, ..., f(i); f(i) is the number of associated devices corresponding to the i-th associated device of the device to be networked; SG i，a It is the device identifier of the ath associated device corresponding to the ith associated device of the device to be networked; the Bluetooth connection mode corresponding to the associated device is bidirectional interconnection through the write connection mode and the notify connection mode.
