Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0042] Secondly, it should be noted that in the description of the embodiments of the present application, the terms "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0043] In addition, it should be noted that in the description of the embodiments of the present application, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] The following first explains the terms involved in this application.

[0046] Heartbeat packet: A self-defined command word that periodically notifies the client and server of their status, and is sent at certain time intervals.

[0047] The technical solutions mentioned in the background technology have at least the following technical problems:

[0048] With the development of computer technology, people have more and more demands for smart home appliances, especially whole-house smart home. In the current whole-house smart home, the types and number of Bluetooth devices are increasing, and some Bluetooth devices themselves do not have the ability to connect to the Internet. They need to use Bluetooth gateways to connect to cloud servers (such as IOT cloud). Therefore, how to quickly and conveniently establish a connection between Bluetooth devices and cloud servers through Bluetooth gateways is the key to completing the whole-house smart home.

[0049] The main problems encountered at present are: when the Bluetooth gateway fails, the Bluetooth devices connected to the Bluetooth gateway will not be able to maintain normal communication with the cloud server; the newly added Bluetooth devices cannot quickly select the appropriate Bluetooth gateway for associated access; when the communication channel of the Bluetooth gateway is congested, some signals will not be able to be transmitted normally; the newly added Bluetooth devices need to manually select the spatial location, which increases the user's operating costs.

[0050] In the prior art, in order to solve the above problems, the connection capability of the Bluetooth gateway is usually improved by increasing the number of Bluetooth gateways or establishing alphabetic gateways. However, there is a problem that a single Bluetooth gateway fails, resulting in communication failure between the Bluetooth device connected to the Bluetooth gateway and the cloud server.

[0051] In response to the above problems, this application proposes a method for establishing a connection for a Bluetooth device, the core idea of ​​which is to set a default Bluetooth gateway and an alternative Bluetooth gateway for the Bluetooth device. Under normal circumstances, the Bluetooth device establishes a connection with the default Bluetooth gateway to achieve communication between the Bluetooth device and the cloud server. If an abnormality occurs in the default Bluetooth device, at this time, the Bluetooth device can establish a connection with the alternative Bluetooth gateway to open the Bluetooth device's backup connection channel, so that the Bluetooth device can communicate with the cloud server through the alternative Bluetooth gateway, thus avoiding the problem that the Bluetooth device cannot communicate with the cloud server when an abnormality occurs in a Bluetooth gateway, thereby achieving the purpose of normal communication between the Bluetooth device connected to the Bluetooth gateway and the cloud server when a single Bluetooth gateway fails.

[0052] In a possible implementation manner, the method for establishing a connection of a Bluetooth device provided in this embodiment may be applied in an application scenario. Figure 1 A schematic diagram of an application scenario of the method for establishing a connection between a Bluetooth device and an embodiment of the present application is provided, such as Figure 1 As shown, in this scenario, all home appliances in the whole family can be in the same Bluetooth gateway network, and the capabilities of the Bluetooth gateway can be integrated into the home appliances, and all home appliances in the family are Bluetooth devices. For example, the kitchen in the family includes multiple Bluetooth devices, among which the capabilities of the Bluetooth gateway can be integrated into the range hood, recorded as Gateway 1; the living room includes multiple Bluetooth devices, among which the capabilities of the Bluetooth gateway can be integrated into the smart screen and the smart air conditioner, recorded as Gateway 2 and Gateway 3 respectively; the bedroom includes multiple Bluetooth devices, among which the capabilities of the Bluetooth gateway can be integrated into the voice speaker and the bedside lamp, recorded as Gateway 4 and Gateway 5 respectively, so that the structure of a distributed Bluetooth gateway can be realized.

[0053] In the above scenario, for the Bluetooth devices in the kitchen, gateway 1 can be set as the default Bluetooth gateway and gateway 2 can be set as the alternative Bluetooth gateway; for the Bluetooth devices in the living room, gateway 2 can be set as the default Bluetooth gateway and gateway 3 can be set as the alternative Bluetooth gateway according to the spatial location, and some Bluetooth devices can even have multiple alternative Bluetooth gateways set; for the Bluetooth devices in the bedroom, gateway 4 can be set as the default Bluetooth gateway and gateway 5 can be set as the alternative Bluetooth gateway according to the spatial location, and some Bluetooth devices can even have multiple alternative Bluetooth gateways set.

[0054] According to the home Bluetooth gateway network provided in the above scenario, each Bluetooth device is set with a default Bluetooth gateway and at least one alternative Bluetooth gateway. In this way, when an abnormality occurs in the default Bluetooth gateway, the Bluetooth device can communicate with the cloud server through the alternative Bluetooth gateway, thereby maintaining normal communication between the Bluetooth device and the alternative Bluetooth gateway.

[0055] In combination with the above scenarios, the technical solution of the method for establishing a connection between Bluetooth devices provided by the present application is described in detail through several specific embodiments below.

[0056] Figure 2 This is a flowchart of a first embodiment of a method for establishing a connection of a Bluetooth device provided in an embodiment of the present application, such as Figure 2 As shown, the connection establishment method of the Bluetooth device is applied to the alternative Bluetooth gateway, and the connection establishment method of the Bluetooth device includes the following steps:

[0057] S201: Receive a heartbeat packet sent by a default Bluetooth gateway, and determine whether the default Bluetooth gateway is abnormal according to the heartbeat packet.

[0058] In this step, the cloud server configures a default Bluetooth gateway and an alternative Bluetooth gateway for the Bluetooth device to access the cloud server. By default, the Bluetooth device accesses the cloud server through the default Bluetooth gateway, and the cloud server may be an IOT cloud.

[0059] In the above scheme, the default Bluetooth gateway of the Bluetooth device can send a heartbeat packet to the alternative Bluetooth gateway of the Bluetooth device through a wireless local area network (WiFi) to inform the alternative Bluetooth gateway of its own online status and connection channel occupancy status. After receiving the heartbeat packet sent by the default Bluetooth gateway, the alternative Bluetooth gateway can determine whether the default Bluetooth gateway is abnormal based on the heartbeat packet. If the alternative Bluetooth gateway can detect the heartbeat packet sent by the default Bluetooth gateway, the alternative Bluetooth gateway can determine that the default Bluetooth gateway is not abnormal; if the alternative Bluetooth gateway cannot detect the heartbeat packet sent by the default Bluetooth gateway, the alternative Bluetooth gateway can determine that the default Bluetooth gateway is abnormal.

[0060] In the above scheme, the alternative Bluetooth gateway cannot detect the heartbeat packet sent by the default Bluetooth gateway. This may be because the alternative Bluetooth gateway has not received the heartbeat packet sent by the default Bluetooth gateway within a period of time, or because the occupancy of the connection channel of the default Bluetooth gateway has reached the maximum number of Bluetooth device connections, the default Bluetooth gateway no longer sends heartbeat packets to the alternative Bluetooth gateway. At this time, the alternative Bluetooth gateway may consider that the default Bluetooth gateway has an abnormality.

[0061] S202: In response to the default Bluetooth gateway being abnormal, sending application information to the cloud server.

[0062] In this step, the application information is used to apply for a first key from the cloud server, where the first key is the key for the default Bluetooth gateway to connect to the Bluetooth device.

[0063] In the above scheme, the first key is the primary connection key, which is maintained by the default Bluetooth gateway, and the default Bluetooth gateway only maintains the first key. By default, the default Bluetooth gateway can establish a secure connection with the Bluetooth device through the first key, and at the same time, the default Bluetooth gateway can verify the first key through the cloud server to obtain the Bluetooth device whitelist of the default Bluetooth gateway from the cloud server.

[0064] In the above scheme, if the alternative Bluetooth gateway considers the default Bluetooth gateway to be abnormal, in order to ensure that the Bluetooth device connected to the default Bluetooth gateway can communicate normally with the cloud server, the alternative Bluetooth device can apply for a first key from the cloud server to establish a connection between the Bluetooth device and the alternative Bluetooth gateway.

[0065] S203: Receive the first key sent by the cloud server.

[0066] In this step, after receiving the application information sent by the candidate Bluetooth gateway, the cloud server may send the first key to the candidate Bluetooth gateway according to the application information.

[0067] S204: In response to the connection request sent by the Bluetooth device, establish a connection with the Bluetooth device according to the first key.

[0068] In this step, after the alternative Bluetooth gateway determines that an abnormality occurs in the default Bluetooth gateway and applies to the server for the first key, if it responds to the connection request sent by the Bluetooth device, it can establish a connection with the Bluetooth device according to the first key to enable the Bluetooth device to communicate with the cloud server through the alternative Bluetooth gateway, thereby achieving the purpose of quickly switching the connected Bluetooth gateway for the Bluetooth device when an abnormality occurs in the default Bluetooth gateway, improving the stability of the channel for the Bluetooth device to upload data to the IOT cloud platform or the remote control channel of the IOT cloud, that is, improving the stability of the communication between the Bluetooth device and the cloud server.

[0069] The technical solution of the method for establishing a connection of the above-mentioned Bluetooth device is described in detail below.

[0070] In one possible implementation, the application information includes a second key, which is the key for the alternative Bluetooth gateway to connect to the Bluetooth device. After sending the application information to the cloud server, it also includes: receiving key verification failure information sent by the cloud server, and the key verification failure information is used to indicate that the second key does not exist in the cloud server.

[0071] In this solution, if the cloud server fails to verify the second key, the cloud server will not send the first key to the alternative Bluetooth gateway. At this time, the cloud server will send key verification failure information to the alternative Bluetooth gateway to inform the alternative Bluetooth gateway that the second key verification failed.

[0072] Figure 3 This is a flowchart of Embodiment 2 of the method for establishing a connection of a Bluetooth device provided in an embodiment of the present application, such as Figure 3 As shown, the method for establishing a connection of a Bluetooth device is applied to a cloud server, and the method for establishing a connection of a Bluetooth device includes the following steps:

[0073] S301: Receive application information sent by the candidate Bluetooth gateway, and verify whether the second key in the application information exists in the cloud server.

[0074] In this step, the application information is used to apply for a first key from the cloud server. The first key is the key for the default Bluetooth gateway to connect to the Bluetooth device, and the second key is the key for the alternative Bluetooth gateway to connect to the Bluetooth device.

[0075] In the above scheme, the cloud server pre-stores the keys corresponding to all Bluetooth gateways. The application information sent by the alternative Bluetooth gateway to the cloud server also includes the second key of the alternative Bluetooth gateway. After the alternative Bluetooth gateway determines that the default Bluetooth gateway is abnormal, when applying for the first key from the cloud server, the cloud server needs to verify its second key first. In this way, after receiving the application information sent by the alternative Bluetooth gateway, the cloud server can compare and verify the second key included in the application information with the key corresponding to the alternative Bluetooth gateway stored in the cloud server, avoiding the situation where the cloud server mistakenly sends the first key due to the illegality of the alternative Bluetooth gateway, thereby improving the security of the Bluetooth device connection.

[0076] S302: If the second key exists in the cloud server, the first key is sent to the alternative Bluetooth gateway.

[0077] In this step, after receiving the application information sent by the alternative Bluetooth gateway, if the second key is verified successfully, that is, the second key exists in the cloud server, the cloud server may send the first key to the alternative Bluetooth gateway.

[0078] In the above solution, the second key is an auxiliary connection key, which is maintained by the alternative Bluetooth gateway. Since the second key acts as a temporary connection key, the alternative Bluetooth gateway cannot directly obtain the Bluetooth device whitelist of the default Bluetooth gateway through the second key.

[0079] In the above scheme, all Bluetooth gateways can establish a connection with the current Bluetooth device after obtaining the first key. In order to prevent the privacy information of the Bluetooth device from being cracked and leaked, all alternative Bluetooth gateways, except the default Bluetooth gateway, need to verify the corresponding second key when applying for the first key from the cloud server. Only after the cloud server verifies the second key, the alternative Bluetooth gateway can obtain the first key and then obtain the Bluetooth device whitelist of the default Bluetooth gateway.

[0080] S303: If the second key does not exist in the cloud server, a key verification failure message is sent to the alternative Bluetooth gateway.

[0081] In this step, the key verification failure information is used to indicate that the second key does not exist in the cloud server.

[0082] In the above scheme, if the cloud server fails to verify the second key, that is, the second key does not exist in the cloud server, the cloud server will not send the first key to the alternative Bluetooth gateway. At this time, the cloud server will send a key verification failure message to the alternative Bluetooth gateway to inform the alternative Bluetooth gateway that the second key verification failed.

[0083] In a possible implementation, sending a first key to an alternative Bluetooth gateway includes: if it is detected that the default Bluetooth gateway is offline, sending the first key to the alternative Bluetooth gateway; and / or, if it is detected that the default Bluetooth gateway is online, sending a channel occupancy query instruction to the default Bluetooth gateway, the channel occupancy query instruction is used to query the occupancy of a connection channel of the default Bluetooth gateway; receiving channel occupancy feedback information sent by the default Bluetooth gateway, the channel occupancy feedback information is used to indicate the occupancy of a connection channel of the default Bluetooth gateway; if the channel occupancy feedback information is used to indicate that the connection channel of the default Bluetooth gateway is occupied, sending the first key to the alternative Bluetooth gateway.

[0084] In this solution, when the cloud server sends the first key to the alternative Bluetooth gateway, it not only needs to verify the second key of the alternative Bluetooth gateway, but also needs to detect whether the default Bluetooth gateway is online and the connection channel occupancy of the default Bluetooth gateway when the second key verification is successful. If the alternative Bluetooth gateway has an abnormality and cannot receive the heartbeat packet sent by the default Bluetooth gateway, the alternative Bluetooth gateway will mistakenly believe that the default Bluetooth gateway has an abnormality and apply for the first key from the cloud server. Therefore, when the cloud server successfully verifies the second key, it also needs to determine the online status of the default Bluetooth gateway and the connection channel occupancy, so as to avoid the problem of the alternative Bluetooth gateway mistakenly applying for the first key.

[0085] In a possible implementation, it also includes: receiving online information sent by the default Bluetooth gateway; updating the first key and the second key; sending the updated first key to the default Bluetooth gateway, and sending the updated second key to the alternative Bluetooth gateway, so that the Bluetooth device can access the cloud server through the updated first key or the updated second key.

[0086] In this solution, if the default Bluetooth gateway is back online, the default Bluetooth gateway will send an online message to the cloud server to inform the cloud server that the default Bluetooth gateway has returned to normal. In order to prevent the privacy information of the Bluetooth device from being cracked and leaked, the cloud server can update the first key and the second key after the default Bluetooth gateway is back online, so that when the Bluetooth device and the cloud server communicate subsequently, the updated first key can be used to establish a connection between the Bluetooth device and the default Bluetooth gateway, or the updated second key can be used to establish a connection between the Bluetooth device and the alternative Bluetooth gateway.

[0087] In a possible implementation, the method further includes: after the candidate Bluetooth gateway establishes a connection with the Bluetooth device for a preset time period, reassigning a default Bluetooth gateway and a candidate Bluetooth gateway to the Bluetooth device.

[0088] In this solution, the connection relationship between the alternative Bluetooth gateway and the Bluetooth device has reached a preset duration, which means that during this period, the default Bluetooth gateway has not been online, or the connection channel of the default Bluetooth gateway has been occupied. Therefore, in order to enable the Bluetooth device to communicate normally with the cloud server, the cloud server can reassign the default Bluetooth gateway and the alternative Bluetooth gateway to the Bluetooth device.

[0089] In the above solution, when the cloud server assigns a default Bluetooth gateway and an alternative Bluetooth gateway to a Bluetooth device, it can assign a default Bluetooth gateway and multiple alternative Bluetooth gateways to the Bluetooth device. The connection relationship between the Bluetooth device and multiple Bluetooth gateways can be as follows: Figure 6 As shown, Figure 6 A schematic diagram of connecting a Bluetooth device and a Bluetooth gateway provided in an embodiment of the present application, in Figure 6 , the connection between Bluetooth device 1 and Bluetooth gateway 1 is the default channel, and the connection between Bluetooth device 1 and Bluetooth gateway 2 is the backup channel, that is, the default Bluetooth gateway of Bluetooth device 1 is Bluetooth gateway 1, and the backup Bluetooth gateway is Bluetooth gateway 2; the connection between Bluetooth device 2 and Bluetooth gateway 1 is the backup channel, and the connection between Bluetooth device 2 and Bluetooth gateway 2 is the default channel, that is, the default Bluetooth gateway of Bluetooth device 2 is Bluetooth gateway 2, and the backup Bluetooth gateway is Bluetooth gateway 1; the connection between Bluetooth device 3 and Bluetooth gateway 1 is the backup channel, and the connection between Bluetooth device 3 and Bluetooth gateway 2 is the default channel, that is, the default Bluetooth gateway of Bluetooth device 3 is Bluetooth gateway 2, and the backup Bluetooth gateway is Bluetooth gateway 1.

[0090] In the above scheme, when a new Bluetooth device joins the Bluetooth gateway network, the cloud server will also assign a default Bluetooth gateway and an alternative Bluetooth gateway to the Bluetooth device, and send the key of the default Bluetooth gateway and the key of the alternative Bluetooth gateway to the Bluetooth device through the default Bluetooth gateway, where the key of the default Bluetooth gateway is used as the primary connection key and the key of the alternative Bluetooth gateway is used as the auxiliary connection key.

[0091] In a possible implementation, assigning a default Bluetooth gateway and an alternative Bluetooth gateway to a Bluetooth device includes: assigning a default Bluetooth gateway and an alternative Bluetooth gateway to a Bluetooth device according to the location of the Bluetooth device; or assigning a default Bluetooth gateway and an alternative Bluetooth gateway to a Bluetooth device according to a signal strength value of a Bluetooth signal sent by the Bluetooth device received by the Bluetooth gateway; or assigning a default Bluetooth gateway and an alternative Bluetooth gateway to a Bluetooth device according to the number of devices connected to the Bluetooth gateway.

[0092] In this solution, the cloud server can assign a default Bluetooth gateway and an alternative Bluetooth gateway to the Bluetooth device through the above three methods, among which the first method (assigning a default Bluetooth gateway and an alternative Bluetooth gateway to the Bluetooth device according to the location of the Bluetooth device) has a higher priority than the second method (assigning a default Bluetooth gateway and an alternative Bluetooth gateway to the Bluetooth device according to the signal strength value of the Bluetooth signal sent by the Bluetooth device received by the Bluetooth gateway), and the second method has a higher priority than the third method (assigning a default Bluetooth gateway and an alternative Bluetooth gateway to the Bluetooth device according to the number of connected devices to the Bluetooth gateway).

[0093] In the above scheme, when a default Bluetooth gateway and an alternative Bluetooth gateway are assigned to a Bluetooth device according to the location of the Bluetooth device, the location of the Bluetooth device can be determined by multiple Bluetooth gateways. For example, the Bluetooth gateway can locate the Bluetooth device according to the angle of arrival (AOA) of the Bluetooth signal sent by the Bluetooth device. Figure 7 shown. Figure 7 A schematic diagram of positioning a Bluetooth device provided in an embodiment of the present application, in Figure 7 In the figure, the distance between Bluetooth gateway 1 and Bluetooth gateway 2 is determined, and the distance can be represented by d; when positioning Bluetooth device 1, after receiving the Bluetooth signal sent by Bluetooth device 1, Bluetooth gateway 1 can determine the arrival angle θ1 of the Bluetooth signal sent by Bluetooth device 1 through the integrated antenna, and after receiving the Bluetooth signal sent by Bluetooth device 1, Bluetooth gateway 2 can determine the arrival angle θ2 of the Bluetooth signal sent by Bluetooth device 1 through the integrated antenna, and the position of Bluetooth device 1 can be determined through θ1, θ2 and d; similarly, when positioning Bluetooth device 2, after receiving the Bluetooth signal sent by Bluetooth device 2, Bluetooth gateway 1 can determine the arrival angle θ4 of the Bluetooth signal sent by Bluetooth device 2 through the integrated antenna, and after receiving the Bluetooth signal sent by Bluetooth device 2, Bluetooth gateway 2 can determine the arrival angle θ3 of the Bluetooth signal sent by Bluetooth device 2 through the integrated antenna, and the position of Bluetooth device 2 can be determined through θ3, θ3 and d. The Bluetooth gateway closest to the Bluetooth device can be used as the default Bluetooth gateway of the Bluetooth device, and other Bluetooth gateways can be used as alternative Bluetooth gateways.

[0094] In the above scheme, when the Bluetooth device is assigned a default Bluetooth gateway and an alternative Bluetooth gateway, the Bluetooth gateway that receives the strongest Bluetooth signal sent by the Bluetooth device can be used as the default Bluetooth gateway of the Bluetooth device, and other Bluetooth gateways can be used as alternative Bluetooth gateways. If a Bluetooth gateway cannot receive the Bluetooth signal sent by the Bluetooth device, the Bluetooth gateway cannot be used as the Bluetooth gateway of the Bluetooth device. The signal strength value of the Bluetooth signal sent by the Bluetooth device received by the Bluetooth gateway can be represented by the received signal strength indication (RSSI).

[0095] In the above scheme, when the default Bluetooth gateway and the alternative Bluetooth gateway are allocated to the Bluetooth device according to the number of connected devices of the Bluetooth gateway, the Bluetooth gateway with the least number of connected devices can be used as the default Bluetooth gateway of the Bluetooth device, and the other Bluetooth gateways are used as alternative Bluetooth gateways.

[0096] In the above solution, the default Bluetooth gateway and the alternative Bluetooth gateway are assigned to the Bluetooth device by combining the above three methods, so that the assignment result can be more reasonable, thereby achieving the purpose of quickly assigning the default Bluetooth gateway and the alternative Bluetooth gateway to the Bluetooth device.

[0097] Figure 4 This is a flowchart of Embodiment 3 of the method for establishing a connection of a Bluetooth device provided in an embodiment of the present application, such as Figure 4 As shown, the connection establishment method of the Bluetooth device is applied to the default Bluetooth gateway, and the connection establishment method of the Bluetooth device includes the following steps:

[0098] S401: Receive a channel occupancy query instruction sent by a cloud server.

[0099] In this step, the channel occupancy query instruction is used to query the connection channel occupancy of the default Bluetooth gateway.

[0100] In the above solution, when the default Bluetooth gateway is online, the cloud server needs to determine the channel occupancy of the default Bluetooth gateway, so as to determine whether the first key can be sent to the alternative Bluetooth gateway.

[0101] S402: Generate channel occupancy feedback information according to the channel occupancy query instruction.

[0102] In this step, the channel occupancy feedback information is used to indicate the connection channel occupancy status of the default Bluetooth gateway.

[0103] In the above scheme, after receiving the channel occupancy query instruction sent by the cloud server, the default Bluetooth gateway needs to feedback its own channel occupancy to the cloud server. Therefore, the channel occupancy feedback information can be generated according to the channel occupancy query instruction.

[0104] S403: Send channel occupancy feedback information to the cloud server.

[0105] In this step, after generating the channel occupancy feedback information, the default Bluetooth gateway may send the channel occupancy feedback information to the cloud server to inform the server of its own channel occupancy status, so that the server can determine whether to send the first key to the alternative Bluetooth gateway according to the channel occupancy feedback information.

[0106] In a possible implementation, it also includes: sending online information to a cloud server; receiving an updated first key sent by the cloud server, the first key being the key for connecting a default Bluetooth gateway to a Bluetooth device; sending the updated first key to the Bluetooth device; and establishing a connection with the Bluetooth device based on the updated first key.

[0107] In this solution, if the default Bluetooth gateway is back online, the default Bluetooth gateway will send an online message to the cloud server to inform the cloud server that the default Bluetooth gateway has returned to normal. In order to prevent the privacy information of the Bluetooth device from being cracked and leaked, the cloud server can update the first key and the second key after the default Bluetooth gateway is back online, so that when the Bluetooth device and the cloud server communicate subsequently, the updated first key can be used to establish a connection between the Bluetooth device and the default Bluetooth gateway, or the updated second key can be used to establish a connection between the Bluetooth device and the alternative Bluetooth gateway.

[0108] Figure 5 This is a flowchart of Embodiment 3 of the method for establishing a connection of a Bluetooth device provided in an embodiment of the present application, such as Figure 5 As shown, the connection establishment method of the Bluetooth device is applied to the Bluetooth device, and the connection establishment method of the Bluetooth device includes the following steps:

[0109] S501: Receive an updated first key sent by a default Bluetooth gateway.

[0110] In this step, the first key is a key for connecting the default Bluetooth gateway to the Bluetooth device.

[0111] In the above solution, since the default Bluetooth gateway has been back online, in order to reestablish the connection between the Bluetooth device and the default Bluetooth gateway, the cloud server needs to send the updated first key to the default Bluetooth gateway, and then the default Bluetooth gateway will forward the updated first key to the Bluetooth device.

[0112] S502: Establish a connection with a default Bluetooth gateway according to the updated first key.

[0113] In this step, since the original first key is no longer usable, the connection between the alternative Bluetooth gateway and the Bluetooth device is automatically disconnected. In this way, after receiving the updated first key sent by the default Bluetooth gateway, the Bluetooth device can re-establish a connection with the default Bluetooth gateway through the updated first key.

[0114] In the above scheme, the Bluetooth device can actively establish a connection with the default Bluetooth device through the key of the default Bluetooth device, and can also actively establish a connection with the alternative Bluetooth gateway through the key of the alternative Bluetooth gateway. Therefore, after the cloud server updates the first key and the second key, it will send the updated first key and the second key to the default Bluetooth gateway at the same time, so that the default Bluetooth gateway can send the updated first key and the updated second key to the Bluetooth device. So that when there is a need later, the Bluetooth device can actively connect to the default Bluetooth device through the updated first key, or actively connect to the alternative Bluetooth gateway through the updated second key.

[0115] In a possible implementation, the further step includes: when no connection response from the default Bluetooth gateway is received, establishing a connection with the alternative Bluetooth gateway according to a second key, where the second key is a key for the alternative Bluetooth gateway to connect to the Bluetooth device.

[0116] In this solution, by default, the Bluetooth device can actively send a connection request to the default Bluetooth gateway to establish a connection with the default Bluetooth gateway. If the default Bluetooth gateway has not responded to the connection request sent by the Bluetooth device, the Bluetooth device can actively establish a connection with the alternative Bluetooth gateway through the second key. At this time, the Bluetooth device can be switched to the master device (Master device) in the area, and the home appliance device integrated with the alternative Bluetooth device can be switched to the slave device (Slave device).

[0117] In the above scheme, the Bluetooth device can actively establish a connection with the alternative Bluetooth gateway through the second key after the number of times it actively connects to the default Bluetooth gateway reaches a preset threshold, for example, twice. At this time, the alternative Bluetooth gateway can temporarily replace the default Bluetooth gateway to complete the Bluetooth gateway work until the default Bluetooth gateway returns to normal.

[0118] In a possible implementation, when the cloud server needs to send a control instruction to a Bluetooth device, by default, the cloud server sends the control instruction to the default Bluetooth gateway, which forwards the control instruction to the Bluetooth device. However, if the default Bluetooth gateway fails to forward the control instruction, the cloud server can actively send the first key to the alternative Bluetooth gateway and open the alternative connection channel, so that the alternative Bluetooth gateway forwards the control instruction to the Bluetooth device. After receiving the control instruction, the Bluetooth device sends the feedback result to the alternative Bluetooth gateway through the alternative connection channel, and the alternative Bluetooth gateway forwards the feedback result to the cloud server. After the default Bluetooth gateway returns to normal, the cloud server updates the first key and the second key, and then reconnects the default Bluetooth gateway and the Bluetooth device.

[0119] In the above solution, the connection status between the Bluetooth device and the Bluetooth gateway and the key information used for the connection may be as shown in Table 1 below:

[0120] Table 1 Connection status between Bluetooth device and Bluetooth gateway and key information table used for connection

[0121]

[0122]

[0123] In the above Table 1, when the Bluetooth gateway is offline, it means that the Bluetooth gateway cannot use WiFi, but can send Bluetooth signals; when the Bluetooth gateway is powered off, it means that the power of the Bluetooth gateway is disconnected, WiFi cannot be used, and Bluetooth signals cannot be sent.

[0124] In one possible implementation, if an abnormality occurs in the connection path between the cloud server and the Bluetooth gateway, that is, the Bluetooth gateway cannot connect to the cloud server, then after the alternative Bluetooth gateway detects that the default Bluetooth gateway has an abnormality, the alternative Bluetooth gateway cannot apply for the first key in the cloud server, and therefore, the alternative Bluetooth gateway cannot upload data to the cloud server. However, since the alternative Bluetooth gateway can communicate with the Bluetooth device through the second key, a temporary connection relationship can be maintained between the alternative Bluetooth gateway and the Bluetooth device to achieve local functions.

[0125] In the method for establishing a connection of a Bluetooth device provided in an embodiment of the present application, the alternative Bluetooth gateway determines whether the default Bluetooth gateway is abnormal by detecting the heartbeat packet sent by the default Bluetooth gateway, and when the alternative Bluetooth gateway determines that the default Bluetooth gateway is abnormal, it applies for the key of the default Bluetooth gateway from the cloud server, so that the Bluetooth device can establish a connection with the alternative Bluetooth gateway using the key of the default Bluetooth gateway, thereby enabling the Bluetooth device and the cloud server to communicate normally, thereby achieving the purpose of enabling the Bluetooth device connected to the Bluetooth gateway to communicate normally with the cloud server when a single Bluetooth gateway fails.

[0126] Generally speaking, this application integrates Bluetooth gateway capabilities into home appliances. The cloud server can automatically assign default Bluetooth gateways and alternative Bluetooth gateways to Bluetooth devices quickly and accurately, and realize the connection between Bluetooth devices and Bluetooth gateways through dual keys. It can not only ensure that all Bluetooth gateways in the Bluetooth gateway network can quickly and conveniently establish a connection relationship with the Bluetooth device using the same key (first key), but also avoid the leakage of privacy information of Bluetooth devices. Therefore, the technical solution provided by this application is a technical implementation solution that can realize normal communication between Bluetooth devices and cloud servers, and ensure that the privacy information of Bluetooth devices is not leaked.
