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 concept of the present application is to provide a new pairing method for a single pairing mode of a host and a slave in the prior art, when a slave (hereinafter referred to as a second slave) which is not paired with a host device needs to be paired with the host device, the second slave is first paired with a slave (hereinafter referred to as a first slave) which is already paired with the host successfully, and after the first slave and the second slave are paired successfully, the first slave sends information of the second slave to the host, so that the host 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 comprises a first slave and at least one second slave; the first slave, the second slave and the host have the same communication protocol, and the first slave is already paired to connect to the host, and the second slave is not yet paired to connect to the host.
In the application, the slave comprises a wireless communication handle and the like, and can be used as a remote controller to control the host; the host computer comprises a game machine, virtual reality glasses, virtual display equipment and other equipment.
The application is implemented in a situation that the first slave, the second slave and the host have the same communication protocol, and the first slave is already paired to connect to the host, and the second slave is not yet paired to connect to the host.
The communication protocol can be any one of the prior art, such as ZigBee wireless protocol, bluetooth communication protocol and the like, and the application is recommended to be more suitable for private communication protocols, such as game scenes. 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 only if the wireless communication protocol used by the master and the slave are identical, which is a precondition that the master slave can be paired successfully.
The first slave generally refers to one of a plurality of slaves in a successfully paired connection with the master, the first slave also being referred to as an old slave; the second slave machine generally refers to a slave machine which has not yet formed a mating connection with the master machine, and may also be referred to as a new slave machine, and may also include a plurality of slave machines.
As shown in fig. 1, when the second slave and the master are in pairing connection, the pairing method includes:
and step S110, the first slave machine and the second slave machine finish pairing connection, and pairing information of the second slave machine is obtained.
The first slave acts as an old slave and is already coupled to the master, and the second slave acts as a new slave and is not yet coupled to the master. When the second slave computer wants to connect to the host computer, the second slave computer is not directly connected with the host computer, but the first slave computer completes pairing connection with the second slave computer.
The pairing connection method may be any one of the prior arts, such as bluetooth connection, where the communication protocol is a private communication protocol, and 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 obtains pairing information of the second slave, such as a device model of the second slave, a device ID of the second slave, and so on.
And step S120, the first slave machine sends the pairing information of the second slave machine to the host machine so that the host 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 paired and connected, the first slave machine sends 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 second slave machine after obtaining the pairing information of the second slave machine, if so, the first slave machine and the second slave machine carry out forced handshake pairing, and if not, the received pairing information is ignored. The pairing operation is firstly carried out between the slaves, so that the use pleasure of a user is increased, and particularly, when the user host is paired with the slaves carried out by other people, the process can be simplified and interesting.
Unlike the single-master pairing connection mode between a master and a slave in the prior art, the method shown in fig. 1 provides a new pairing method, in which a first slave paired with the master is first paired with a second slave that is not yet paired with the master, pairing information of the second slave is obtained and sent 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 temporarily connect a new remote control device or a friend of the user wants to connect a host device of the user by using the remote control device carried by the user, the pairing connection process is more interesting by adopting the method, and the method is particularly suitable for a game scene with a private communication protocol.
In some embodiments of the present application, in the above method for pairing a master slave, the first slave and the second slave complete pairing connection, and obtaining pairing information of the second slave includes: the first slave and the second slave are both set to corresponding pairing modes, wherein the first slave is set to a receiving mode, the second slave is set to a transmitting mode, and the second slave broadcasts own pairing information externally 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 analyzes the received broadcast message of the second slave to obtain the pairing information of the second slave, and judges whether the pairing information of the second slave meets the preset pairing requirement; and when the first slave machine judges that the pairing information of the second slave machine accords with the preset pairing requirement, the first slave machine completes pairing handshake with the second slave machine and stores the pairing information of the second slave machine.
The first slave machine and the second slave machine can be paired only when both are in the pairing mode, so that when the first slave machine and the second slave machine need to be paired, a user can manually set both the first slave machine and the second slave machine to the corresponding pairing mode. The first slave machine is set to a receiving mode, and is used as a receiver to receive the equipment information of the second slave machine, and meanwhile, an indicator lamp of the first slave machine enters a receiving flashing 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; the second slave enters a transmitting mode as a sender to broadcast the self equipment information, and meanwhile, an indicator light of the second slave enters a transmitting flashing mode or a display screen of the second slave displays or the first slave outputs a sound to prompt a user that the second slave enters the transmitting mode.
After the first slave machine and the second slave machine are mutually close by a user, the distance between the first slave machine and the second slave machine is smaller than the communication distance, for example, after the optimal communication distance is achieved, the first slave machine receives the broadcast message of the second slave machine, analyzes the received broadcast message of the second slave machine, obtains the pairing information of the second slave machine, and further judges whether the pairing information of the second slave machine meets the preset pairing requirement or not, wherein the pairing information comprises the equipment model of the second slave machine, the equipment ID of the second slave machine and the like. The pairing requirement can be set according to actual needs, if the second slave and the first slave are required to be peer devices, if the first slave obtains that the second slave is also a wireless communication handle through analyzing the broadcast message, the second slave and the first slave are considered to be peer devices, and the preset pairing requirement is met. Of course, other pairing requirements can be set according to actual needs, for example, the first slave machine obtains the equipment model of the second slave machine through analyzing the broadcast message, but the second slave machine can be considered to not meet the pairing requirements if the version of the second slave machine is found to be old and cannot meet the game requirements.
And 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 accords with the preset pairing requirement, the first slave machine temporarily stores the pairing information of the second slave machine, and simultaneously sends a request for agreeing to pair to the second slave machine, so that pairing handshake is completed with the second slave machine, after the second slave machine agrees to pair with the first slave machine, the indicator lamps of the first slave machine and the second slave machine flash at the same frequency, or a prompt for successful pairing of the first slave machine and the second slave machine is displayed through a display screen of the first slave machine and the second slave machine or is prompted through sound.
Since the communication protocols between the first slave and the second slave are consistent, the consistency refers to that the slaves can be mutually identified without confirmation by a user. Therefore, when the first slave machine and the second slave machine are in the pairing mode, the first slave machine and the second slave machine can be mutually identified according to certain information in the broadcast information, and when the two parties confirm that certain information in the broadcast information meets the requirement, automatic pairing is started, the information of the two parties is recorded into respective micro control units (Microcontroller Unit, MCU) to complete pairing of the two slave machines.
The broadcast message of the second slave machine at least comprises a start mark, a stop mark and pairing information, the pairing information of the second slave machine is between the start mark and the stop mark, and when the first slave machine receives the broadcast message sent by the second slave machine, the information between the start mark and the stop 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 adopts the following broadcast information format: the method comprises the steps that I, startStr I UUID I DeviceType I … … I EndStr I, wherein Startstr and Endstr are respectively a start mark and a stop mark, pairing information of a second slave is in the middle of a Startstr character string and an Endstr character string, UUID (Universally Unique Identifier) is an identification code uniquely corresponding to the second slave, namely a device mark of the second slave, and DeviceType is a device type of the second slave; and when the first slave receives the broadcast message, analyzing the information between the Startstr character string and the Endstr character string to obtain the pairing information of the second slave.
The communication protocol format |startstr|uuid|devicetype| … … |endstr| used above is commonly used in proprietary communication protocols, where StartStr, endstr is the beginning and ending label. When the first slave receives the broadcast message in the communication protocol format, the information in the middle of the Startstr and Endstr character strings is analyzed, and pairing information such as a device tag UUID and a device type DeviceType which are uniquely corresponding to the second slave is obtained.
The purpose of using the device to tag the UUID is to enable all elements in the distributed system to have unique identification information, and no identification information specification is required by the central control end, so that each device can create a UUID that does not conflict with other devices. In this embodiment, the device is used to mark the UUID, and the first slave is capable of distinguishing the plurality of second slaves according to the UUID, so as to determine whether each second slave meets the preset pairing requirement.
For example, in some embodiments of the present application, there are a plurality of second slaves, and when a first slave receives broadcast messages of the plurality of second slaves, the plurality of second slaves are distinguished according to the parsed UUIDs, and pairing handshakes are sequentially performed with each of the second slaves according to the time sequence of the received broadcast messages of the plurality of second slaves.
When the second slaves have a plurality of second slaves, the first slaves can receive the plurality of broadcast messages, the first slaves set a receiving time stamp for each broadcast message when receiving the broadcast messages, the first slaves can obtain a plurality of UUIDs after analyzing the received plurality of broadcast messages, and the first slaves can distinguish the plurality of second slaves according to the UUIDs because the UUIDs of the second slaves are different and pair handshake with each second slave in sequence according to the received time stamp information of the received broadcast messages of the plurality of second slaves.
In some embodiments of the present application, the master performs forced handshake pairing with the second slave according to pairing information of the second slave includes: the host analyzes the pairing information of the second slave machine sent by the first slave machine, obtains the equipment mark UUID uniquely corresponding to the second slave machine and stores the equipment mark UUID; the host performs forced handshake pairing with the second slave according to the UUID of the equipment mark of the second slave, and prompts a user after the pairing is completed; the method for prompting the user comprises the following steps: prompting that the second host is successfully connected with the host through the host; and/or prompting the second host to be successfully connected with the host through the second host.
In this embodiment, the prompting manner may specifically be: displaying that the second host is successfully connected with the host on display equipment of the host; or the second host computer prompts the user that the second host computer is successfully connected with the host computer in the forms of vibration, sound and lamplight.
After the first slave machine and the second slave machine finish pairing, the first slave machine acquires pairing information of the second slave machine, the pairing information of the second slave machine is sent 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 a device mark UUID uniquely corresponding to the second slave machine, and preferably, the first slave machine directly sends the analyzed device mark UUID and the device 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. And then the host device performs forced handshake connection with the second slave device according to the UUID, the device type and other information of the second slave device, the second slave device can perform communication operation with the host device after the forced handshake connection is completed, meanwhile, the display device of the host device displays that the host device is successfully connected with a certain second slave device through the first slave device, such as a new game handle or a controller, or the second host device prompts a user that the second host device is successfully connected with the host device through vibration, sound and lamplight, and then the first slave device and the second slave device can simultaneously control the host device.

in step S210, the second slave (unpaired connection master) is set to the transmitting mode, while the first slave (paired connection master) is set to the receiving mode, and the second slave broadcasts its own configuration information through a broadcast message.
Step S220, the first slave analyzes the received broadcast message, and analyzes the pairing information of the second slave, wherein the pairing information comprises the equipment mark and the equipment type which are uniquely corresponding to the second slave.
In step S230, the first slave determines whether the second slave and the first slave meet the preset pairing requirement?
If not, go to step S241, where the first slave ignores the broadcast message;
if yes, step S240 is entered, where the first slave completes the pairing connection with the second slave, temporarily stores the device tag and the device type uniquely corresponding to the second slave in the MCU of the first slave, and sends the device tag uniquely corresponding to the second slave to the master.
Step S250, the host finishes forced handshake pairing according to the device mark uniquely corresponding to the second slave and the second slave corresponding to the device mark, and prompts the user to finish pairing.
