Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The idea of the present invention is to provide a new pairing method for a single master and slave pairing mode in the prior art, wherein when a slave that is not paired with a master device (hereinafter referred to as a second slave) needs to be paired with the master device, the second slave is first paired with a slave that has been successfully paired with the master device (hereinafter referred to as a first slave), and after the first slave and the second slave are successfully paired, the first slave transmits information of the second slave to the master device, so that the master device and the second slave complete forced pairing.
Fig. 1 illustrates a master-slave pairing method according to one embodiment of the present application. The slave machines comprise a first slave machine and at least one second slave machine; the first slave, the second slave and the host have the same communication protocol with each other, the first slave is paired and connected to the host, and the second slave is not paired and connected to the host.
In the application, the slave machine comprises a wireless communication handle and the like and can be used as a remote controller to control the master machine; the host computer comprises a game machine, virtual reality glasses, a virtual display device and the like.
The application is implemented in a situation that the first slave, the second slave and the master have the same communication protocol with each other, the first slave is already paired and connected to the master, and the second slave is not yet paired and connected to the master.
The communication protocol can be any one of the prior art, such as a ZigBee wireless protocol, a Bluetooth communication protocol and the like, and the method is recommended, and is more suitable for a private communication protocol, such as a game scene. The first slave, the second slave and the master are required to have the same communication protocol with each other, because the master and the slave can be paired and connected only if the wireless communication protocols used by the master and the slave are consistent, which is a precondition that the master and the slave can be paired successfully.
The first slave generally refers to one of the slaves that has already made a successful pairing connection with the master, and is also referred to as the old slave; the second slave generally refers to a slave that has not yet formed a pairing connection with the master, and the second slave is also referred to as a new slave, and may include a plurality of slaves.
As shown in fig. 1, when the second slave is paired with the master, the pairing method includes:
and step S110, completing pairing connection between the first slave machine and the second slave machine, and acquiring pairing information of the second slave machine.
The first slave is used as an old slave and is already paired and connected to the master, and the second slave is used as a new slave and is not yet paired and connected to the master. When the second slave wants to be connected to the master, the second slave is not directly connected with the master, but the first slave and the second slave complete pairing connection first.
The pairing connection method may be any one of the prior art, such as bluetooth connection, where in a case that the communication protocol is a private communication protocol, the pairing connection is implemented according to the private communication protocol, and after the pairing connection between the first slave and the second slave is successful, the first slave acquires pairing information of the second slave, such as a device model of the second slave, a device ID of the second slave, and the like.
And step S120, the first slave machine sends the pairing information of the second slave machine to the master machine, so that the master machine performs forced handshake pairing with the second slave machine according to the pairing information of the second slave machine.
After the first slave machine and the second slave machine are successfully connected in a pairing mode, the first slave machine sends the pairing information of the second slave machine to the host machine, the host machine judges whether the second slave machine meets the pairing requirement of the host machine after obtaining the pairing information of the second slave machine, if yes, the host machine carries out forced handshake pairing with the second slave machine, and if not, the received pairing information is omitted. By carrying out pairing operation between the slave machines, the use pleasure of a user is increased, and particularly when the user host machine is paired with the slave machines of other people, the process becomes simple and interesting.
Different from the pairing connection mode in which the master is solely used as the master between the master and the slave in the prior art, the method shown in fig. 1 provides a new pairing method, in which a first slave paired and connected with the master performs pairing connection with a second slave that is not paired and connected with the master, acquires pairing information of the second slave and sends the pairing information to the master, and then the master performs forced handshake pairing with the second slave according to the received pairing information of the second slave. When a user wants to connect a new remote control device temporarily or a friend of the user wants to connect a host device of the user by using a remote control device carried by the user, the method enables the pairing connection process to be more interesting, and is particularly suitable for a game scene with a private communication protocol.
In some embodiments of the present application, in the master-slave pairing method, the first slave and the second slave complete pairing connection, and acquiring pairing information of the second slave includes: the first slave machine and the second slave machine are set to corresponding pairing modes, wherein the first slave machine is set to a receiving mode, the second slave machine is set to a sending mode, and the second slave machine externally broadcasts the pairing information of the second slave machine through a broadcast message.
When the distance between the first slave machine and the second slave machine is smaller than the communication distance, the first slave machine receives the broadcast message of the second slave machine; the first slave machine analyzes the received broadcast message of the second slave machine to obtain the pairing information of the second slave machine, and judges whether the pairing information of the second slave machine meets the preset pairing requirement; and when the first slave machine judges that the pairing information of the second slave machine meets the preset pairing requirement, finishing pairing handshake with the second slave machine and storing the pairing information of the second slave machine.
Therefore, when the first slave machine and the second slave machine need to be paired and connected, a user can manually set the first slave machine and the second slave machine to the corresponding pairing modes. The first slave machine is set to be in a receiving mode and used as a receiving party to receive the equipment information of the second slave machine, and meanwhile, an indicator lamp of the first slave machine enters a receiving flicker mode, or is displayed on a display screen of the first slave machine, or the first slave machine outputs sound to prompt a user that the first slave machine enters the receiving mode; and the second slave machine enters a sending mode and is used as a sender to broadcast the self equipment information, and meanwhile, an indicator lamp of the second slave machine enters a sending flicker mode or a display screen of the second slave machine displays or the first slave machine outputs sound to prompt a user that the second slave machine enters the sending mode.
After the user brings the first slave and the second slave close to each other and the distance between the first slave and the second slave is smaller than the communication distance, for example, the optimal communication distance is reached, the first slave receives the broadcast message of the second slave and analyzes the received broadcast message of the second slave to obtain pairing information of the second slave, wherein the pairing information includes, for example, the device model of the second slave, the device ID of the second slave, and the like, and further determines whether the pairing information of the second slave meets a preset pairing requirement. The pairing requirement can be set according to actual needs, and if the second slave machine and the first slave machine are required to be peer devices, and if the first slave machine obtains that the second slave machine is also a wireless communication handle and the like through analysis of the broadcast message, the second slave machine and the first slave machine are considered to be peer devices, that is, the preset pairing requirement is met. Of course, other pairing requirements may also be set according to actual needs, for example, the first slave machine obtains the device model of the second slave machine through analysis of the broadcast message, but if the version of the second slave machine is old and cannot meet the game requirement, the second slave machine may be considered not to meet the pairing requirements.
When the first slave machine judges that the pairing information of the second slave machine does not meet the preset pairing requirement, the first slave machine ignores the received pairing information. When the first slave machine judges that the pairing information of the second slave machine meets the preset pairing requirement, the first slave machine temporarily stores the pairing information of the second slave machine, simultaneously sends a pairing approval request to the second slave machine, so that pairing handshake is completed with the second slave machine, and after the second slave machine and the first slave machine both approve pairing, indicator lamps of the first slave machine and the second slave machine flicker at the same frequency, or display is performed through display screens of the first slave machine and the second slave machine, or prompt that the first slave machine and the second slave machine are successfully paired is prompted through sound.
Since the communication protocol between the first slave and the second slave is consistent, the consistency means that the slaves can recognize each other without user confirmation. Therefore, when the first slave and the second slave are both in the pairing mode, the first slave and the second slave can recognize each other according to some information in the broadcast information, when the two slaves confirm that some information in the broadcast information meets the requirements, automatic pairing is started, and the information of the two slaves is recorded into respective Micro Control Units (MCUs) to complete the pairing of the two slaves.
The broadcast message of the second slave machine at least comprises a starting mark, a terminating mark and pairing information, the pairing information of the second slave machine is between the starting mark and the terminating mark, and when the first slave machine receives the broadcast message sent by the second slave machine, the information between the starting mark and the terminating mark is analyzed to obtain the pairing information of the second slave machine, wherein the pairing information of the second slave machine at least comprises a device mark and a device type which are uniquely corresponding to the second slave machine.
In some embodiments of the present application, the broadcast message of the second slave is in the following broadcast information format: the slave device identifier is a Unique identifier of the second slave device, namely a device identifier of the second slave device, and the DeviceType is a device type of the second slave device; and when the first slave machine receives the broadcast message, analyzing the information in the middle of the Startstr and Endstr character strings to obtain the pairing information of the second slave machine.
The communication protocol format | StartStr | UUID | DeviceType | … … | EndStr | adopted above is mostly used in the private communication protocol, where StartStr, EndStr are the labels of the beginning and the end. When the first slave machine receives the broadcast message in the communication protocol format, the first slave machine analyzes the information in the middle of the Startstr and Endstr character strings to obtain the pairing information such as the equipment mark UUID and the equipment type DeviceType which are uniquely corresponding to the second slave machine.
The purpose of using the device tag UUID is to allow all elements in the distributed system to have unique identification information without the need for identification information designation by the central control side, so that each device can create a UUID that does not conflict with other devices. In this embodiment, the UUID is marked by the device, and the first slave machine can distinguish the plurality of second slave machines according to the UUID, so as to respectively determine whether each second slave machine meets the preset pairing requirement.
For example, in some embodiments of the present application, there are a plurality of second slaves, and when the first slave receives broadcast messages of the plurality of second slaves, the first slave distinguishes the plurality of second slaves according to the parsed UUIDs, and performs pairing handshake with each second slave in turn according to the time sequence of the received broadcast messages of the plurality of second slaves.
When a plurality of second slaves are provided, the first slave receives a plurality of broadcast messages, the first slave sets a receiving timestamp for each broadcast message when receiving the broadcast messages, the first slave analyzes the received broadcast messages to obtain a plurality of UUIDs, and the UUIDs of the second slaves are different, so that the first slave can distinguish the second slaves according to the UUIDs and sequentially perform pairing handshake with the second slaves according to the receiving timestamp information of the received broadcast messages of the second slaves.
In some embodiments of the present application, the master performing the forced handshake pairing with the second slave according to the pairing information of the second slave includes: the host machine analyzes the pairing information of the second slave machine sent by the first slave machine to obtain and store a unique device mark UUID corresponding to the second slave machine; the host machine carries out forced handshake pairing with the second slave machine according to the equipment mark UUID of the second slave machine, and prompts a user after pairing is finished; the mode of prompting the user comprises the following steps: the host prompts that the second host is successfully connected with the host; and/or prompting the second host computer to be successfully connected with the host computer through the second host computer.
In this embodiment, the prompting manner may specifically be: displaying that the second host is successfully connected with the host on the display equipment of the host; or the second host prompts the user that the second host is successfully connected with the host through vibration, sound and light.
After the first slave machine and the second slave machine are paired, the first slave machine acquires the pairing information of the second slave machine and sends the pairing information of the second slave machine to the host machine equipment, the host machine analyzes the pairing information of the second slave machine sent by the first slave machine to obtain the equipment mark UUID uniquely corresponding to the second slave machine, and preferably, the first slave machine directly sends the analyzed equipment mark UUID and the equipment type to the host machine, so that the process that the host machine needs to analyze the pairing information of the second slave machine is omitted. Then, the master machine device performs forced handshake connection with the second slave machine according to information such as a device identifier UUID and/or a device type of the second slave machine, the second slave machine can perform communication operation with the master machine after the forced handshake connection is completed, meanwhile, a display device of the master machine device displays that the master machine is successfully connected with a certain second slave machine through the first slave machine, for example, a new gamepad or a controller, or the second master machine prompts a user that the second master machine is successfully connected with the master machine through vibration, sound and light forms, and then the first slave machine and the second slave machine can simultaneously control the master machine.

in step S210, the second slave (unpaired connection master) is set to be in the transmission mode, and the first slave (paired connection master) is set to be in the reception mode, and the second slave broadcasts its configuration information through a broadcast message.
Step S220, the first slave machine parses the received broadcast message, and parses the pairing information of the second slave machine, where the pairing information includes the device identifier and the device type uniquely corresponding to the second slave machine.
In step S230, the first slave determines whether the second slave and the first slave meet the preset pairing requirement?
If not, the step S241 is executed, and the first slave machine ignores the broadcast message;
if yes, the process proceeds to step S240, where the first slave completes pairing connection with the second slave, temporarily stores the device identifier and the device type uniquely corresponding to the second slave in its own MCU, and sends the device identifier uniquely corresponding to the second slave to the master.
And step S250, the host completes forced handshake pairing with the second slave machine corresponding to the equipment mark according to the equipment mark uniquely corresponding to the second slave machine, and prompts a user to complete pairing.
