Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations. In addition, although the division of the functional modules is performed in the apparatus schematic, in some cases, the division of the modules may be different from that in the apparatus schematic.
The term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
In order to facilitate understanding of the embodiments of the present application, some of the background of the application referred to in the embodiments of the present application will be briefly described below.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of a data transmission method according to the prior art according to an embodiment of the present application. As shown in fig. 1, when a master device and a slave device connected based on a bluetooth mode in the prior art perform data transmission, a broadcast packet is typically sent to the master device by starting a broadcast mode of the slave device, and then the master device can start a scan mode to discover the slave device and receive the broadcast packet. Wherein the broadcast packet carries a small amount of data that both need to be transmitted, so the master device can receive data based on the broadcast packet to achieve transmission of both data.
However, the security of the data transmission mode is low, and since the bluetooth device that starts the scanning mode within a certain range can acquire the broadcast packet and acquire the carried data, the privacy of the data is not protected. In addition, since there is no data transmission channel, the master device may not successfully acquire the broadcast packet transmitted from the slave device, thereby causing data transmission failure of both.
With continued reference to fig. 2, fig. 2 is a schematic diagram of a scenario of another data transmission method according to the prior art according to an embodiment of the present application. As shown in fig. 2, another data transmission method in the prior art needs to establish a data transmission channel based on a master device and a slave device connected in a bluetooth manner. Specifically, when the master device and the slave device perform data transmission based on the data transmission channel, operation steps such as pairing and binding of the two parties are required to be realized. Because the operation steps are complicated, the energy consumption of both equipment can be correspondingly increased. In addition, in order to ensure the quality of data transmission, the number of slave devices to which the master device can be simultaneously connected has a certain limit.
Therefore, it is necessary to propose a data transmission method to improve the success rate of data transmission between devices and reduce the energy consumption in the data transmission process of both devices.
Referring to fig. 3 and fig. 4, fig. 3 is a schematic diagram illustrating steps of a data transmission method according to an embodiment of the application; fig. 4 is a schematic view of a scenario of a data transmission method according to an embodiment of the present application. The data transmission method can be applied to a communication system, wherein the communication system comprises a master device and at least one slave device, and the master device and the slave devices can be connected in a Bluetooth mode.
As shown in fig. 1, the data transmission method includes steps S11 to S14.
Step S11: the master device receives broadcast data packets sent by a plurality of slave devices.
Wherein the master device is a data receiver; the slave device is the data sender.
The present application is not limited to the master device and the slave device. For example, the main device may be a terminal such as a computer, a mobile phone, a tablet, etc.; the slave equipment is provided with a Bluetooth headset, an intelligent electronic weight scale, an intelligent electronic sphygmomanometer and the like.
It can be understood that the data transmission method provided by the application can be applied to the scenes of reporting state changes to the terminal by the Bluetooth headset, uploading weight data to the terminal by the intelligent electronic weight scale, uploading blood pressure data to the terminal by the intelligent electronic sphygmomanometer and the like, and the application is not limited to the situations.
Further, when the slave device performs data transmission with the master device, the slave device can transmit a broadcast data packet to the master device in a broadcast mode, so that the master device can receive the broadcast data packet in a scanning state.
In the embodiment of the application, the main equipment only needs to be in a scanning state to receive the broadcast packet, so that compared with the mode of carrying out data transmission based on the data transmission channels, the method provided by the application can reduce the energy consumption of the data transmission of the two equipment sides and improve the duration of the two equipment sides.
Step S12: the master device determines whether the corresponding slave device is a target slave device based on the broadcast packet.
The broadcast data packet may carry identification code information of the slave device, device information, etc., which is not limited in the present application.
And the master device can judge whether the corresponding slave device is the target slave device based on the information so as to realize verification of the identity of the slave device and improve the safety of data transmission.
In the embodiment of the application, the master device can verify the received broadcast data packet to confirm whether the slave device is a target slave device capable of realizing data transmission, thereby improving the safety of data transmission and preventing the data privacy from being revealed.
Step S13: when the corresponding slave device is the target slave device, the master device sets the self-scanning state to be the active scanning state, and sends data transmission request information to the target slave device so that the target slave device receives the data transmission request information.
It will be appreciated that when the corresponding slave device is the target slave device, it is indicated that the master device may perform data transmission with the target slave device. At this time, the master device sets its own scanning state to an active scanning state, and the target device performs data transmission with the target slave device without receiving information sent by devices other than the target device.
Further, the master device may send data transmission request information to the target slave device, so as to enable the target slave device to receive the data transmission request information.
Optionally, after the master device determines whether the corresponding slave device is the target slave device based on the broadcast data packet, the method includes: after the corresponding slave device is not the target slave device, the master device sets the self-scanning state to the passive scanning state.
It can be understood that when the corresponding slave device is not the target device, it is indicated that the slave device cannot perform data transmission with the master device, and at this time, the master device sets the self-scanning state to the passive scanning state. As such, the master device cannot conduct data transmission with devices other than the non-target device.
In the embodiment of the application, when the corresponding slave device is the target slave device, the identity of the corresponding slave device is legal, so that the target slave device can perform data transmission with the master device. In order to improve the safety and the transmission efficiency of the two transmission processes, the master device can set the self-scanning state to be an active scanning state so as to establish communication with the target slave device only and further realize the transmission of data of the two parties.
Step S14: the master device receives response information when the target slave device transmits the response information to the master device based on the data transmission request information, wherein the response information includes the data information.
It will be appreciated that since the response information includes data information. Therefore, the master device can receive the data information sent by the target slave device, and further realize data transmission of the master device and the slave device.
The data transmission method disclosed by the embodiment of the application can be applied to the master equipment and at least one slave equipment which are connected in a Bluetooth mode. The master device can determine whether the corresponding slave device is the target slave device or not by receiving the broadcast data packet sent by the slave device, and when the corresponding slave device is the target slave device, set the self-scanning state to be the active scanning state so as to send a request for data transmission to the target slave device, so that the target slave device can send response information comprising data information to the master device, and therefore the master device can receive the data information sent by the target slave device, and further realize data transmission between the master device and the slave device. The master device only needs to receive the data packet sent by the target slave device through the scanning state, so that the data transmission can be realized without always maintaining the connection with the target slave device, and the energy consumption in the data transmission process of the two devices is reduced. In addition, the risk of data transmission failure caused by equipment connection failure is avoided, and the success rate of data transmission is improved.
With continued reference to fig. 5, fig. 5 is a schematic diagram of steps for determining whether a corresponding slave device is a target slave device according to an embodiment of the present application. As shown in fig. 5, the broadcast data packet includes identification data, and the master device may determine whether the corresponding slave device is a target slave device through steps S121 to S122.
Step S121: the main equipment judges whether the identification data is in a preset database or not.
The present application is not limited to the identification data, and may be, for example, identification code data, identification information data, or the like.
Specifically, the preset database includes a plurality of legal identification data, so that after receiving the broadcast data packet, the master device can determine whether the identification data in the broadcast data packet is in the preset database, so as to verify the validity of the identity of the slave device.
Step S122: if the identification data is in the preset database, the corresponding slave device is determined to be the target slave device.
It can be understood that if the identification data is in the preset database, the identity of the corresponding slave device is legal, so that the corresponding slave device can be determined to be the target slave device.
In the embodiment of the application, the master device can verify the legitimacy of the identity of the slave device based on the identity recognition data so as to improve the safety of data transmission of the master device and the slave device and prevent the data privacy from being revealed.
With continued reference to fig. 6, fig. 6 is a schematic diagram illustrating steps of another data transmission method according to an embodiment of the application. As shown in fig. 6, data transmission can also be achieved through steps S21 to S26.
Step S21: the master device receives broadcast data packets sent by a plurality of slave devices.
Step S22: the master device determines whether the corresponding slave device is a target slave device based on the broadcast packet.
The specific description of step S21 to step S22 refers to step S11 to step S12, and the description thereof is omitted herein for avoiding repetition.
Step S23: the master device determines the number of target slave devices based on the broadcast data packets.
Step S24: when the corresponding slave device is the target slave device, the master device sets the self-scanning state to be the active scanning state, and sends data transmission request information to the target slave device so that the target slave device receives the data transmission request information.
Step S25: the master device receives response information when the target slave device transmits the response information to the master device based on the data transmission request information, wherein the response information includes the data information.
Specifically, the master device may determine the number of senders through the received broadcast packets, and further determine the number of target slave devices.
When the number of target slave devices is 1, the master device may set the self-scanning state to the active scanning state and transmit data transmission request information to the target slave device so that the target slave device receives the data transmission request information. And further, when the target slave device transmits response information to the master device based on the data transmission request information, the master device receives the response information, wherein the response information comprises the data information. Thus, data transmission between the master device and the target slave device is realized.
Step S26: the master device sets the self-scanning state to the passive scanning state.
Since there is only one target slave device, the master device can set its own scan state to be a passive scan state after completing data transmission with the target slave device. As such, the master device cannot communicate data with other non-target devices.
In the embodiment of the application, after the data transmission of the master device and the target slave device is completed, the scanning state of the master device and the target slave device can be set to be a passive scanning state, so that the data transmission with other devices which are not target devices can not be performed. In this way, reduced power consumption of the host device and prevention of data privacy from being compromised is achieved.
Optionally, when the number of the target slave devices is greater than one, the master device sets the self-scanning state to the active scanning state, and sends the data transmission request information to the target slave device, so that the target slave device receives the data transmission request information, including: the master device sets the self-scanning state to be an active scanning state, and sends data transmission request information to any one target slave device so that the data transmission request information is received by any one target slave device.
Specifically, when the number of target slave devices is greater than one, the master device may set the self-scanning state to an active scanning state, and perform data transmission with any one of the target slave devices until the data transmission with the target slave device is successful.
On the basis of the above embodiment, when the target slave device transmits response information to the master device based on the data transmission request information, the master device receives the response information, and then includes: the master device sets the self-scanning state to be an active scanning state and sequentially receives response information of other target slave devices.
It can be understood that after completing data transmission with one of the target slave devices, the master device may continue to set its own scanning state to an active scanning state, and sequentially receive response information of the other target slave devices until data transmission with all the target slave devices is successful. Therefore, the quality of data transmission between the master device and the target slave device can be improved, and the probability of failure of data transmission is reduced.
Optionally, the data transmission request information includes authentication information, and the data transmission request information is sent to the target slave device, so that the target slave device after receiving the data transmission request information includes: and verifying the legitimacy of the identity of the master device based on the authentication information by the target slave device.
On the basis of the above embodiment, when the target slave device transmits response information to the master device based on the data transmission request information, the master device receives the response information, including: and after the target slave device verifies that the identity of the master device is legal, and sends response information to the master device based on the data transmission request information, the master device receives the response information.
It will be appreciated that the slave device may verify the authentication information to confirm that the identity of the master device is legitimate. Further, when the authentication information is successful in verification, the identity of the master device is legal, and identity authentication between the master device and the slave device is achieved. Further, the slave device may transmit response information to the master device based on the data transmission request information, so that the master device receives the response information. The authentication of the identity of the main equipment is realized by the process, so that the safety of the data transmission process is improved.
