[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0051] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0052] In related technologies, the BLE (Bluetooth Low Energy) connection method uses a point-to-point connection method, that is, an independent connection needs to be established between two devices that need to communicate and interact, which makes the connection between devices cumbersome, and the number of other devices that can be connected to the same device based on BLE connection is limited, which makes it difficult to meet the needs of multi-device interconnection. In complex scenarios such as smart homes, users usually need to connect to multiple smart devices at the same time based on mobile terminals, such as smart bulbs, thermostats, cameras, etc., and traditional BLE connection methods make it difficult to achieve such many-to-many connections.

[0053] Secondly, BLE connection in related technologies has certain challenges in data transmission efficiency between devices. BLE may experience data packet loss or delay during data transmission, especially in the case of high-density device connections, which will cause communication congestion and reduce the stability and efficiency of data transmission.

[0054] In view of the above limitations and challenges of BLE technology, and the requirements for multi-device interconnection and communication, the present disclosure proposes a chained BLE networking technology. By adopting a linked list structure of BLE networking, multiple smart devices are connected to solve the problems of multi-device connection stability and data transmission efficiency in BLE technology, and achieve more efficient and stable multi-device communication and collaboration.

[0055] Figure 1 is a schematic diagram of a Bluetooth communication system according to an exemplary embodiment. Figure 1 As shown, the system includes: a first device, a second device and a third device.

[0056] The first device is used to send low-power Bluetooth BLE chain networking information to the second device, where the BLE chain networking information is used to instruct the second device and the third device to join the BLE chain networking;

[0057] The second device is used to join the BLE chain networking according to the BLE chain networking information, and send the BLE chain networking information to the third device;

[0058] A third device is used to join the BLE chain networking according to the BLE chain networking information;

[0059] The first device is also used to generate a networking mapping relationship in response to determining that the second device and the third device join the BLE chain network, and send the networking mapping relationship to the second device and the third device through the BLE chain network, wherein the networking mapping relationship includes a one-to-one correspondence between multiple device IDs and multiple BLE networking addresses.

[0060] For example, in this embodiment, a BLE chain network is formed based on the first device, the second device and the third device, and the chain communication between the devices is realized through the BLE chain network. In the BLE chain network, a chain connection is made between the devices, that is, the first device and the second device communicate with each other via Bluetooth via BLE, and the second device communicates with the third device via Bluetooth. Among them, the first device is the main device, and the control instructions are sent to other devices based on the BLE chain network through the main device. Before establishing the BLE chain network, the first device sends the BLE chain networking information to the second device, wherein the first device and the second device establish a wireless communication connection through BLE Bluetooth communication.

[0061] It is worth mentioning that the embodiments of the present disclosure are applicable to usage scenarios in which multiple smart devices exist, such as usage scenarios of smart home appliances. The first device is a master control device, which can be a user's mobile terminal, a master control platform, a central control terminal, etc. In this usage scenario, the user can control other smart devices in the scenario by operating the master control device. In this usage scenario, the first device can search for multiple other smart devices based on BLE technology. The first device numbers the multiple other smart devices based on the user's selection, determines the second device and the third device, and establishes a BLE communication connection with the second device, and then sends BLE chain networking information to the second device.

[0062] Based on the BLE communication between the second device and the first device, after receiving the BLE chain networking information, the second device joins the BLE chain networking and sends the BLE chain networking information to the third device. The second device may include one or more intelligent devices. When there is one second device, the BLE chain networking constructed by the current first device, the second device and the third device is three devices connected by a single line; when there are multiple second devices, the networking mode between the second devices is also a single-line connection, in which the head device receives the BLE chain networking information sent by the first device, and gradually transmits the information to other devices through the single-line networking, and then transmits it to the third device by the tail device. For example, the BLE chain networking information includes a BLE chain networking sequence. After the second device receives the BLE chain networking information, it searches for other smart devices in the current usage environment based on BLE Bluetooth communication by consulting the BLE chain networking sequence, determines the third device in the BLE chain networking from multiple searched smart devices, and after establishing a BLE communication connection with the third device, sends the BLE chain networking information to the third device.

[0063] The third device joins the BLE chain networking based on the received BLE chain networking information, and sends feedback information to the first device based on the BLE chain networking when determining that the current device is the end device of the BLE chain networking based on the BLE chain networking information. For example, the third device sends feedback information to the second device through the BLE chain networking, and the second device sends information on successful device joining to the first device based on the received feedback information, so as to prompt the first device that other devices in the BLE chain networking have joined the BLE chain networking. When the first device determines that the second device and the third device have both joined the BLE chain networking based on the BLE chain networking, the first device generates a network mapping relationship, wherein the network mapping relationship includes the device ID information of each device and the address information of each device in the BLE chain networking. The first device sends the networking mapping relationship to the first device and the second device through the BLE chain networking, so that other devices in the BLE chain networking can determine the position of each device in the network, as well as the upstream and downstream devices of the current device in the BLE chain networking based on the networking mapping relationship. Through the BLE chain networking method, each device in the network can establish a BLE communication connection with at most two other devices, avoiding the connection stability problems and data transmission efficiency problems caused by one device connecting to multiple devices, and realizing efficient and stable multi-device communication and collaboration.

[0064] For example, Figure 2 is a schematic diagram of a BLE chain networking structure according to an exemplary embodiment. Figure 2 As shown, the BLE chain network includes device A, device B, device C and device D.

[0065] In the BLE chain networking, device A is connected to device B, device B is connected to device C, and device C is connected to device D. In this way, BLE communication connection is performed, and based on the connected devices A, B, C, and D, a BLE chain networking is formed.

[0066] Optionally, in some embodiments, the system further comprises: a fourth device;

[0067] The first device is further used to send link adding information to the second device, where the link adding information is used to instruct the second device to add the fourth device to the BLE chain networking;

[0068] The second device is further configured to establish a BLE communication connection with a fourth device in response to receiving the link adding information;

[0069] a fourth device, configured to establish a BLE communication connection with a third device in response to establishing the BLE communication connection;

[0070] The third device is further configured to disconnect the communication connection with the second device in response to establishing a BLE communication connection with the fourth device.

[0071] For example, in this embodiment, the fourth device is a device that needs to be newly added to the BLE chain networking. When the user determines that the fourth device needs to be newly added to the BLE chain networking, the link addition information is sent to the second device through the BLE chain networking. For example, the link addition information includes the device ID information of the fourth device, and the link addition information is used to instruct the second device to add the fourth device to the BLE chain networking. After receiving the link addition information, the second device searches for the fourth device from the current use environment based on the device ID of the fourth device in the link addition information and based on BLE communication, and after searching for the fourth device, establishes a BLE communication connection with the fourth device. After the fourth device establishes a BLE communication connection with the second device, it can obtain the network mapping relationship corresponding to the current BLE chain networking, determine the relevant information of the third device, which is the downstream device of the second device, and then search for the third device from the current environment based on the device ID of the third device in the network mapping relationship, based on BLE communication, and establish a BLE communication connection between the fourth device and the third device. After the third device establishes a BLE communication connection with the fourth device, it disconnects the communication connection with the second device. Based on the above method, a fourth device is added to the BLE chain network, thereby realizing the extension demand of the BLE chain network.

[0072] Optionally, in some embodiments, the first device is also used to update the networking mapping relationship in response to determining that the fourth device joins the BLE chain network according to the position of the fourth device in the BLE chain network; and send the updated networking mapping relationship to the second device, the third device and the fourth device.

[0073] For example, in this embodiment, when the fourth device joins the BLE chain network, it is necessary to update the network mapping relationship in each device based on the newly established BLE chain network. For example, based on the position of the fourth device in the BLE chain network, the fourth device and other downstream devices after the fourth device are reallocated addresses, and the network mapping relationship in each device is updated based on the newly allocated address.

[0074] For example, Figure 3 is a schematic diagram of a BLE chain networking dynamic addition according to an exemplary embodiment, such as Figure 3 As shown, add a new device to the BLE chain network in the following way.

[0075] (1) In the existing BLE chain network (device A connects to device B, and device B connects to device D), device A sends link addition information to device B, so that device B is connected to device C;

[0076] (2) Device C connects to device D again, and then disconnects the connection between device B and device D. Based on the newly connected BLE chain network, it notifies other devices in the chain network to update the network mapping relationship.

[0077] Optionally, in some embodiments, the first device is further configured to establish a BLE communication connection with the third device according to the networking mapping relationship in response to the second device disconnecting the communication connection with the first device and the third device;

[0078] In response to establishing a BLE communication connection with a third device, the networking mapping relationship is updated.

[0079] For example, in this embodiment, the first device monitors the connection status of other devices in the network based on the BLE chain networking. When it is determined that the second device disconnects the communication connection between the first device and the third device, the third device, which is the downstream device of the second device, is searched for in the current usage scenario according to the networking mapping relationship, and a BLE communication connection is established between the third devices. After establishing the BLE communication connection with the third device, update information is sent to other devices in the newly constructed BLE chain networking, so that other devices update the networking mapping relationship.

[0080] For example, Figure 4 is a schematic diagram of deleting a node in a BLE chain networking according to an exemplary embodiment. Figure 4 shown.

[0081] In the currently established BLE chain network (device A is connected to device B, device B is connected to device C, and device C is connected to device D), the node of device C needs to be deleted.

[0082] (1) Device C notifies the upstream and downstream devices in the BLE chain network and disconnects from devices B and D. Then device B notifies the remaining nodes to update the network mapping relationship.

[0083] (2) Disconnect the connection between device C and device D first, and then disconnect the connection between device B and device C. Device D then turns on BLE broadcasting and searches for device B in the current usage environment. Device B then connects to device D based on the ID information of device D in the network mapping relationship, thus forming a new BLE chain network.

[0084] Optionally, in some embodiments, the first device is further used to send control information to the second device according to the BLE chain networking, and the control information is used to control the third device;

[0085] The second device is further configured to send the received control information to the third device according to the networking mapping relationship;

[0086] The third device is further used to execute corresponding control actions according to the control information.

[0087] For example, in this embodiment, the first device sends control information to other devices based on BLE chain networking. For example, the first device needs to control the third device based on BLE chain networking. The control information is first sent to the second device through BLE chain networking. It is worth mentioning that the control information includes the device ID corresponding to the third device. After receiving the control information, when the second device determines that the control information is not the control information of the second device based on the device ID, the control information is transmitted to the downstream third device based on the BLE chain networking. When the third device determines that the control information is the control information of the third device based on the device ID, it executes the control information to complete the corresponding control action.

[0088] Through the above method, the first device is used to send low-power Bluetooth BLE chain networking information to the second device, the BLE chain networking information is used to instruct the second device and the third device to join the BLE chain networking, the second device is used to join the BLE chain networking according to the BLE chain networking information, and send the BLE chain networking information to the third device, the third device is used to join the BLE chain networking according to the BLE chain networking information, the first device is also used to respond to the determination that the second device and the third device join the BLE chain networking, generate a networking mapping relationship, and send the networking mapping relationship to the second device and the third device through the BLE chain networking, and the networking mapping relationship includes a one-to-one correspondence between multiple device IDs and multiple BLE networking addresses. Thus, by constructing a network topology with a chain structure, efficient communication and writing between multiple Bluetooth devices can be achieved to meet the interconnection needs between multiple devices in the fields of the Internet of Things and smart homes.

[0089] Figure 5 is a flowchart of a Bluetooth communication method according to an exemplary embodiment, which is applied to a Bluetooth communication system, wherein the Bluetooth communication system includes a first device, a second device and a third device, such as Figure 5 As shown, the method includes the following steps.

[0090] In step S101, the first device sends Bluetooth low energy consumption (BLE) chain networking information to the second device, where the BLE chain networking information is used to instruct the second device and the third device to join the BLE chain networking.

[0091] In step S102, the second device joins the BLE chain networking according to the BLE chain networking information, and sends the BLE chain networking information to the third device.

[0092] In step S103, the third device joins the BLE chain networking according to the BLE chain networking information.

[0093] In step S104, the first device generates a BLE chain networking table in response to the second device and the third device joining the BLE chain networking, and sends the BLE chain networking table to the second device and the third device through the BLE chain networking, wherein the BLE chain networking table includes a one-to-one correspondence between multiple device IDs and multiple BLE networking addresses.

[0094] For example, the Bluetooth communication method in this embodiment is the same as the Bluetooth communication method in the above embodiment, and reference may be made to the above embodiment, which will not be described in detail here.

[0095] Optionally, in some implementations, the system further includes a fourth device, and the method further includes:

[0096] The first device sends link adding information to the second device, where the link adding information is used to instruct the second device to add the fourth device to the BLE chain networking;

[0097] In response to receiving the link adding information, the second device establishes a BLE communication connection with the fourth device;

[0098] In response to establishing the BLE communication connection, the fourth device establishes a BLE communication connection with the third device;

[0099] In response to establishing a BLE communication connection with the fourth device, the third device disconnects the communication connection with the second device.

[0100] In the above manner, the first device sends low-power Bluetooth BLE chain networking information to the second device, and the BLE chain networking information is used to instruct the second device and the third device to join the BLE chain networking. The second device joins the BLE chain networking according to the BLE chain networking information, and sends the BLE chain networking information to the third device. The third device joins the BLE chain networking according to the BLE chain networking information. The first device generates a network mapping relationship in response to determining that the second device and the third device join the BLE chain networking, and sends the network mapping relationship to the second device and the third device through the BLE chain networking. The network mapping relationship includes a one-to-one correspondence between multiple device IDs and multiple BLE network addresses. Thus, by constructing a network topology with a chain structure, efficient communication and writing between multiple Bluetooth devices can be achieved to meet the interconnection needs between multiple devices in the fields of the Internet of Things and smart homes.

[0101] Figure 6 is a flowchart of a Bluetooth communication method according to an exemplary embodiment, which is applied to a first device in a Bluetooth communication system, such as Figure 6 As shown, the method includes the following steps.

[0102] In step S201, low-power Bluetooth BLE chain networking information is sent to the second device in the Bluetooth communication system. The BLE chain networking information is used to instruct the second device to send the BLE chain networking information to the third device in the Bluetooth communication system, and to instruct the second device and the third device to join the BLE chain networking.

[0103] In step S202, in response to determining that the second device and the third device join the BLE chain networking, a networking mapping relationship is generated.

[0104] In step S203, the networking mapping relationship is sent to the second device and the third device through the BLE chain networking, and the networking mapping relationship includes a one-to-one correspondence between multiple device IDs and multiple BLE networking addresses.

[0105] Through the above method, low-power Bluetooth BLE chain networking information is sent to the second device in the Bluetooth communication system. The BLE chain networking information is used to instruct the second device to send the BLE chain networking information to the third device in the Bluetooth communication system, and to instruct the second device and the third device to join the BLE chain networking. In response to determining that the second device and the third device join the BLE chain networking, a network mapping relationship is generated, and the network mapping relationship is sent to the second device and the third device through the BLE chain networking. The network mapping relationship includes a one-to-one correspondence between multiple device IDs and multiple BLE networking addresses. Thus, by constructing a chain-structured network topology, efficient communication and writing between multiple Bluetooth devices can be achieved to meet the interconnection needs between multiple devices in the fields of the Internet of Things and smart homes.
