[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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 those skilled in the art without creative work are within the scope of protection of the present application.

[0048] Figure 1 FIG. 1 is a flow chart of a control system of a BLE smart device according to an embodiment of the present application. Figure 1 As shown, the system includes a BLE smart device, a server, and a terminal that is not directly connected to the BLE smart device (corresponding to Figure 1 "Terminal B" in the BLE smart device) and the terminal directly connected to the BLE smart device (corresponding to Figure 1 According to some embodiments, the BLE smart device is a smart device using the BLE protocol, which may include smart door locks, temperature and humidity sensors, smart switches, smart lights, and other devices; the server may use various suitable servers, such as cloud servers; the terminal A and the terminal B may include mobile phones, tablets, notebooks, and other terminals. This application does not impose any restrictions on the specific device forms and versions of the BLE smart device, server, terminal A, and terminal B.

[0049] Comparison Figure 1 In the embodiment shown, the workflow of the control system includes:

[0050] 1. Terminal A establishes a long connection with the server.

[0051] According to some embodiments, the protocols used by the long connection at the transport layer include TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), and the MQTT (Message Queuing Telemetry Transport) protocol and other suitable protocols may be used at the application layer, and this application does not impose any restrictions on this. Figure 1 As shown, terminal A establishes a connection with the server through the TCP protocol to ensure that both parties can communicate.

[0052] 2. Terminal A and the BLE smart device establish a BLE connection.

[0053] Terminal A establishes a connection with the Bluetooth Low Energy (BLE) smart device through the BLE protocol to control the BLE smart device.

[0054] 3. The user of terminal B opens the corresponding application (App) and prepares to operate and control the BLE smart device.

[0055] 4. Terminal B establishes a long connection with the server.

[0056] As mentioned above, the protocols used by the long connection at the transport layer include TCP and / or UDP, and the MQTT (Message Queuing Telemetry Transport) protocol and other suitable protocols can be used at the application layer, and this application does not impose any restrictions on this. Figure 1 As shown, terminal B establishes a connection with the server through the TCP protocol to ensure that both parties can communicate.

[0057] 5. Terminal B sends a query request to the server to query the online terminal that has established a direct connection with the BLE smart device.

[0058] 6. The server pushes instructions to terminal A.

[0059] The server pushes the command to terminal A and asks it for its online status, that is, whether it is directly connected to the BLE smart device.

[0060] 7. Terminal A replies the online status to the server.

[0061] After receiving the instruction from the server, terminal A replies with its current online status, and the reply content includes online and offline.

[0062] 8. The server pushes the online instruction to terminal B.

[0063] If terminal A is online, the server pushes the online status information of terminal A to terminal B.

[0064] 9. Terminal B sends control instructions to the server.

[0065] After confirming that there is a terminal directly connected to the BLE smart device, terminal B decides to control the BLE smart device and sends the control command to the server.

[0066] 10. The server pushes the control command to terminal A.

[0067] After receiving the control instruction from terminal B, the server forwards the instruction to terminal A.

[0068] 11. Terminal A sends the control command to the BLE smart device:

[0069] After receiving the command from the server, terminal A sends the control command to the BLE smart device through the BLE connection.

[0070] 12. The BLE smart device reports the response to the control command to terminal A:

[0071] After executing the control command, the BLE smart device generates a response and reports it to terminal A.

[0072] 13. Terminal A reports the response to the server.

[0073] After receiving the response from the BLE smart device, terminal A reports the response to the server through the TCP connection.

[0074] 14. The server pushes a response to terminal B.

[0075] After receiving the control response from terminal A, the server pushes the response to terminal B.

[0076] After terminal B learns about terminal A that is directly connected to the BLE smart device through the server, it forwards the control instructions for the BLE smart device through terminal A. However, if terminal B does not monitor the online status of terminal A, if terminal A changes from an online state to an offline state due to some reasons (for example, network disconnection, user killing the process), terminal B may need to receive a timeout message to discover it. If terminal B can monitor the online status of terminal A, it can effectively prevent the situation where terminal A accidentally goes offline and cannot be detected in time. To this end, the present application also provides a heartbeat mechanism to facilitate terminal B to monitor the online status of terminal A in real time.

[0077] Figure 2This is a flowchart of a control system of a BLE smart device according to another embodiment of the present application. 1. Terminal A establishes a long connection with the server.

[0078] According to some embodiments, the protocols used by the long connection at the transport layer include TCP and / or UDP, and the MQTT protocol and other suitable protocols may be used at the application layer, and this application does not impose any restrictions on this. Figure 1 As shown, terminal A establishes a connection with the server through the TCP protocol to ensure that both parties can communicate.

[0079] 2. Terminal A and the BLE smart device establish a BLE connection.

[0080] Terminal A establishes a connection with the Bluetooth Low Energy (BLE) smart device through the BLE protocol to control the BLE smart device.

[0081] 3. Terminal B establishes a long connection with the server.

[0082] As mentioned above, the protocols used by the long connection at the transport layer include TCP and / or UDP, and the MQTT (Message Queuing Telemetry Transport) protocol and other suitable protocols can be used at the application layer, and this application does not impose any restrictions on this. Figure 1 As shown, terminal B establishes a connection with the server through the TCP protocol to ensure that both parties can communicate.

[0083] 4. Terminal B sends a query request to the server to query the online terminal that has established a direct connection with the BLE smart device.

[0084] 5. The server pushes instructions to terminal A.

[0085] The server pushes the command to terminal A and asks it for its online status, that is, whether it is directly connected to the BLE smart device.

[0086] 6. Terminal A replies the online status to the server.

[0087] After receiving the instruction from the server, terminal A replies with its current online status, and the reply content includes online and offline.

[0088] 7. The server pushes the online instruction to terminal B.

[0089] If terminal A is online, the server pushes the online status information of terminal A to terminal B.

[0090] 8. Terminal B starts the heartbeat signal timer:

[0091] After receiving the online notification from terminal A, terminal B starts a heartbeat signal timer. The timer is used to monitor the reception of the heartbeat signal. If the heartbeat signal is not received within the preset time, terminal B will consider terminal A to be offline.

[0092] 9. Terminal A pushes heartbeat to the server.

[0093] Terminal A periodically sends heartbeat signals to the server to indicate that it is online.

[0094] 10. The server pushes the heartbeat signal to terminal B.

[0095] After receiving the heartbeat signal from terminal A, the server forwards the signal to terminal B.

[0096] 11. Terminal B resets the heartbeat signal timer.

[0097] After receiving the heartbeat signal, terminal B will reset the heartbeat timer and start the time again. In this way, if terminal A continues to stay online, terminal B can periodically receive the heartbeat signal and continuously reset the timer.

[0098] 12. The cycle of the heartbeat mechanism.

[0099] This process will continue to cycle to ensure that the online status of terminal A is continuously monitored. If terminal B does not receive a heartbeat signal within a cycle and the heartbeat timer times out, terminal B will determine that terminal A is offline and take corresponding measures. The measures taken include, for example, sending a query request to the server again to query the terminal directly connected to the BLE smart device.

[0100] In addition, in order to ensure the security of the entire system, this application can also introduce the following security designs:

[0101] Design 1: Communication within the same security domain

[0102] In the case of 1 and Figure 2 In the illustrated embodiment, terminal A and terminal B are placed in the same security domain to communicate with each other, ensuring that only authorized terminals can participate in the communication.

[0103] Design 2: TLS encryption

[0104] All data transmitted through the TCP channel is encrypted based on TLS (Transport Layer Security), establishing a secure TLS encrypted session to prevent data from being eavesdropped or tampered with during transmission.

[0105] Design 3: End-to-end encryption

[0106] The transmitted content is also end-to-end encrypted. A shared symmetric key exists in the same security domain, and encryption such as AES / GCM is performed using the symmetric key to ensure that the data cannot be cracked even if it is intercepted during transmission.

[0107] Design 4: Authentication and Authorization

[0108] Each terminal is authenticated before accessing the system to ensure that only legitimate terminals can access the system. At the same time, the communication and operation between terminals are also carried out in the same security domain, and terminals in different security domains cannot communicate.

[0109] Through the above process and design, this application achieves the goal of remote, multi-terminal control of BLE smart devices without a gateway, while ensuring the security of the system and real-time monitoring of the terminal's online status.
