In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0062] First, refer to Figure 1 The present invention provides a Bluetooth one-to-many communication method, which is executed by a host and includes:

[0063] S110, obtaining a preset secondary host determination algorithm;

[0064] S120, screening the slaves of the master according to the secondary master determination algorithm to obtain at least one secondary master;

[0065] S130, obtaining registration information of all slaves of the host, wherein the slaves include the secondary host, the first slave and the second slave;

[0066] S140, generating ID information according to the time sequence of the acquired registration information;

[0067] S150, allocating ID information to the secondary host, the first slave, and the second slave according to a preset allocation order;

[0068] S160, outputting the identity information and the token information to the sub-host, the first slave, and the second slave according to the acquired control instruction, so as to control at least one of the sub-host, the first slave, and the second slave to output broadcast data;

[0069] S170, acquiring broadcast data outputted by at least one of the secondary host and the first slave.

[0070] By executing the Bluetooth one-to-many communication method provided by the present invention, the host can screen all slaves that have communication interaction with the host according to the obtained sub-host judgment algorithm, and obtain at least one sub-host according to the screening result. The host can also generate ID information and distribute the ID information to all slaves in chronological order by receiving the registration information of all slaves. The host outputs identity information and token information by receiving a control instruction to control at least one of the sub-host, the first slave and the second slave that matches the identity information to obtain token information, so that at least one of the corresponding sub-host, the first slave and the second slave outputs broadcast data, and obtains the broadcast data output by at least one of the sub-host and the first slave. This method divides all slaves into a sub-host, a first slave and a second slave, so that when the host communicates with all slaves, by adding ID information to all slaves, and controlling the corresponding sub-host, the first slave and the second slave to obtain token information to output broadcast data according to the identity information matching result, avoids the process of matching authentication with all slaves one by one, and effectively improves the communication efficiency of the host when facing a large number of slaves. During the whole process, the host only receives the broadcast data output by the first slave and the secondary host, which reduces the process of obtaining broadcast data, reduces the occupation of host resources, and effectively improves the communication quality.

[0071] In some specific embodiments, the preset allocation order may be the time sequence of receiving the registration information output by all slaves, or may be the order specified by the system for outputting broadcast data to different slaves according to user requirements, but is not limited thereto.

[0072] In some other embodiments, the host only receives the broadcast data output by the sub-host and the first slave, and the broadcast data output by the second slave is collected by the sub-host directly communicating with it and then uniformly output to the host. Through this method, the host can receive the broadcast information of all slaves only by communicating with the sub-host and the first slave, thereby improving the communication efficiency of the host, reducing the resource occupation of the host, and improving the communication quality.

[0073] In some other embodiments, the identity information may be a data packet including one or a group of ID information, which is output to all slaves through directional broadcasting to control the slaves to match the identity information with the corresponding slave ID information to enable that specific slave to output broadcast data.

[0074] Reference Figure 2 In some embodiments, step S140 includes:

[0075] S141, sorting the first slave and the second slave according to the time sequence to obtain a slave sequence;

[0076] S142, marking the first slave and the second slave according to the slave sequence to obtain ID information of the first slave and the second slave.

[0077] In the present Bluetooth communication process, the host sorts the first slave and the second slave connected to the host according to the time sequence of the registration information obtained, and can obtain the slave sequence. The host can also mark the first slave and the second slave according to the slave sequence. In this way, the host can sort the slaves corresponding to the obtained registration information to achieve the management of each slave. Specifically, the host can perform a directional wake-up of the slave corresponding to the ID information according to different slave ID information, avoiding the occupation of a large amount of system resources in a short period of time due to simultaneous communication and interaction with multiple slaves, and reducing the risk of decreased communication quality and unstable communication connection. It can be understood that the preset allocation order can be the time sequence of the registration information output by the slave obtained by the host, or it can be the allocation order preset by the user according to the needs. The host allocates the ID information to each slave in turn according to the preset allocation order. The ID information can be a number arranged in ascending order of natural numbers, or it can be other symbols that can include sequential logic, but is not limited to this.

[0078] Reference Figure 3 In some embodiments, step S160 includes:

[0079] S161, obtaining a preset broadcast interval time;

[0080] S162, output the identity information and token information in sequence according to the broadcast interval time.

[0081] In the Bluetooth communication process, the host obtains a preset broadcast interval time, and according to the broadcast time interval, sends identity information and token information to at least one of the sub-host, the first slave and the second slave in sequence. By setting the broadcast time interval, the host outputs the corresponding identity information according to the ID information awakened as needed, so that within the preset broadcast time interval, the slave corresponding to the ID information can receive the identity information, thereby achieving the matching of the ID information and the identity information, and then, the slave can receive the token information and output the broadcast data directly or indirectly to the host. Through this method, the host only needs to communicate with the sub-host, the first slave or the second slave whose identity information and ID information can match at the same time to obtain the broadcast data, effectively avoiding the host communicating with other sub-hosts, the first slave and the second slave while communicating with the sub-host, the first slave or the second slave whose identity information and ID information can match, so that a large amount of system resources are occupied in a short time, resulting in problems such as reduced communication quality or unstable communication connection. This method can improve the stability of the Bluetooth one-to-many communication method.

[0082] In some specific embodiments, the broadcast time interval depends on the broadcast interval and the broadcast delay. The broadcast time interval varies for different system settings, but it is understandable that the system preset broadcast time interval should meet the minimum time required for the host to communicate with the corresponding sub-host, the first slave and the second slave.

[0083] Reference Figure 4 In some embodiments, the Bluetooth one-to-many communication method further includes:

[0084] S170, setting a transmission channel corresponding to the secondary host;

[0085] S180, the host obtains the broadcast data sent by the sub-host according to the transmission channel corresponding to the sub-host.

[0086] During the Bluetooth communication process, the host can set and allocate the transmission channels of multiple slaves obtained through the screening and processing of the sub-host determination algorithm, and obtain the broadcast data output by different sub-hosts according to the corresponding transmission channels, which effectively improves the efficiency of the host in obtaining broadcast data. It is understandable that the communication connections made by the host through different transmission channels should be independent, and can realize the communication interaction between the host and multiple sub-hosts at the same time without occupying too many communication resources, and will not cause interference due to different broadcast data obtained by each host, thereby improving communication efficiency.

[0087] Second, refer to Figure 5 The present invention provides a Bluetooth one-to-many communication method, which is executed by a secondary host and includes:

[0088] S210, obtaining broadcast data output by the second slave according to the identity information and token information output by the master;

[0089] S220, feeding back the broadcast data to the host.

[0090] The method can obtain the broadcast data output by the second slave according to the identity information and token information output by the host through the sub-host, and send the broadcast data to the host. The method can obtain the broadcast data of the second slave with which the sub-host has a communication connection, and output the broadcast data of the second slave to the host, thereby solving the problems of low transmission efficiency and poor transmission quality caused by the communication interaction between the host and multiple second slaves, and effectively improving the communication quality and communication efficiency.

[0091] In some specific embodiments, each sub-host can simultaneously output the broadcast data output by the second slave with which it has information interaction according to the transmission channel set by the host. It can be understood that for multiple sub-hosts, each sub-host only accepts the broadcast data output by the second slave with which it has direct communication interaction. For the second slave with which it does not have direct communication interaction, the sub-host will not obtain its broadcast data. This method can avoid repeated acquisition and repeated submission of data and reduce the waste of system resources.

[0092] In some other embodiments, the sub-host may execute the one-to-many Bluetooth communication method as in the embodiment of the first aspect of the present invention to divide the second slave machine that has communication interaction with the sub-host into a subordinate sub-host and a subordinate second host. The sub-host may further improve the efficiency of acquiring the broadcast data output by the second slave machine corresponding to the sub-host by executing the one-to-many Bluetooth communication method as in the embodiment of the first aspect of the present invention.

[0093] Thirdly, refer to Figure 6 The present invention provides a Bluetooth one-to-many communication method, which is executed by a second slave, comprising:

[0094] S310, outputting registration information to the host according to the preset instruction;

[0095] S320, obtaining ID information generated by the host according to the registration information, and adjusting the second slave to a dormant state;

[0096] S330, obtaining identity information and token information output by the host;

[0097] S340, maintaining a dormant state or outputting broadcast data to the secondary host according to the ID information, identity information and token information.

[0098] The second slave of the method can output registration information in an undirected broadcast mode according to the preset instructions built locally, and obtain the ID information output by the host to adjust to a dormant state; the method can also judge according to the identity information and token information output by the host obtained, and control the second slave to continue to be in a dormant state or output broadcast data to the secondary host. Through this method, the second slave can obtain the ID information output by the host according to the preset order, and store the ID information. At the same time, the current state can be adjusted to a dormant state to reduce power consumption; the second slave can also obtain the identity information and token information, and maintain the dormant state or output broadcast data to the secondary host according to the ID information, identity information and token information. Through this method, the second slave can output broadcast data to the secondary host with which it realizes communication interaction according to the wake-up sequence preset by the system, effectively reducing the problem of unstable communication and high communication delay caused by the resource load generated by the direct communication interaction between the second slave and the host. In addition, the second host can automatically adjust the working state of the second slave according to the ID information, identity information and token information to reduce power consumption, and can also realize the communication interaction between the second slave and the host.

[0099] In some other embodiments, the first slave can directly communicate with the host. The first slave can also output registration information to the host through non-directional broadcast according to preset instructions, and adjust the first slave to a dormant state according to the ID information generated by the host through directional broadcast and output according to the registration information; the first slave can obtain the identity information and token information output by the host through directional broadcast, and match the identity information and ID information to control the first slave to be in a dormant state or output broadcast data to the host. Among them, the first slave matches according to the identity information and ID information. When the identity information and ID information are consistent, the current state is adjusted to the working state, and the broadcast data is output to the host. At the same time, the current state is adjusted to the dormant state; when the identity information and ID information are inconsistent, the first slave is kept in a dormant state. Through this method, the first slave can complete communication interaction with the host while reducing power consumption.

[0100] Reference Figure 7 In some embodiments, S340 includes:

[0101] S341, if the identity information is consistent with the ID information of the second slave, the current state is adjusted from the sleep state to the working state

[0102] S342, output broadcast data to the secondary host according to the token information, and adjust the current state to the sleep state

[0103] During the Bluetooth communication process, the second slave will match the ID information output by the host and stored by the second slave according to the acquired identity information. When the identity information is consistent with the ID information of the second slave, the current state will be adjusted from the sleep state to the working state, and the token information will be obtained to obtain the authority to output the broadcast data. After obtaining the authority, the broadcast data will be output to the sub-host through directional broadcasting. After the broadcast data output is completed, the second slave will adjust the working state to the sleep state again to reduce the standby power consumption. Through this method, the second host can adjust the current state to the working state by matching the identity information in the low-power sleep state, receive the token information output by the host in the working state, authorize the output of the broadcast data through the token information, and adjust the working state back to the sleep state after the output of the broadcast data. This method enables multiple second slaves to output broadcast data to the host through the sub-host in turn according to the rotation of the token, reducing the resource load of the host and improving the stability of the communication process.

[0104] In some embodiments, step S340 includes:
