Disclosure of Invention

The embodiment of the application provides a networking method and electronic equipment, and networking operation is simple and efficiency is high.

The first aspect provides a networking method applied to a first device. In the method, a first device transmits a first broadcast and emits ultrasound at a first frequency. The second device may also transmit the first broadcast, as well as ultrasonic waves at the second frequency. In one embodiment, if a third device is also included in the networking scenario, the third device may also transmit the first broadcast, as well as ultrasound at a third frequency. The frequencies of the ultrasonic waves emitted by the different devices are different so that the other devices can identify the first device, the second device and the third device. The first broadcast sent by the first device comprises the identification of the first device and the first device, the first broadcast sent by the second device comprises the identification of the second device, the first broadcast sent by the third device comprises the identification of the third device, and the first broadcast is used for discovering other devices. In the following, the networking scenario including the first device and the second device is taken as an example to describe the steps executed by the third device, and reference may be made to the description related to the second device.

The device may also monitor the first broadcast from the other device and detect the ultrasonic waves from the other device while transmitting the first broadcast and the ultrasonic waves. The second device receives the first broadcast and ultrasonic waves with the first frequency, the second device sends response signals to the first device, and accordingly, the first device can receive the response signals from the second device. Wherein the response signal characterizes the reception by the second device of the first broadcast and the ultrasound of the first frequency.

In response to a response signal of the second device, the first device negotiates with the second device, and when the first device is determined to be the master device, the first device transmits a second broadcast, wherein the second broadcast comprises: the identity of the first device, and the identity of the Wi-Fi direct channel. The second device, in response to the second broadcast, may establish a connection with the first device on the Wi-Fi direct channel according to the identity of the first device.

After the first device establishes connection with the second device, the first device negotiates with the second device to obtain a first session key, and the first device uses connection information encrypted by the first session key, where the connection information includes: the service set identifies the SSID and password. The first device sends the connection information encrypted by the first session key to the second device, the second device responds to the connection information encrypted by the first session key, the encrypted connection information can be decrypted by using the first session key to obtain an SSID and a password, and the second device can establish encrypted connection with the first device according to the SSID and the password. The second device establishes encryption connection with the first device, so that data transmission security between the first device and the second device can be ensured.

In the application, the networking process does not need multiple operations of users, the networking efficiency is high, all the devices can be connected with each other, the same router is not needed, and the application range is wide. In addition, different devices can emit ultrasonic waves with different frequencies, and the purpose is that: devices in the same room are determined to network with the devices in the same room. If the second device receives the first broadcast of the first device, the second device and the first device can be in the same room or different rooms, but if the second device receives the ultrasonic wave with the first frequency, the second device and the first device are represented to be in the same room, so that the first device and the second device in the same room can be networked, erroneous connection is avoided, and networking accuracy can be improved.

In one possible implementation, after the first device receives the response signal from the second device, the first device negotiates with the second device to determine the master device, e.g., the device with the strongest processing capability may be the master device. In one possible implementation, the first device and the second device negotiation may determine candidate masters, which may be at least one. Wherein when the candidate master device is one, the candidate master device may be regarded as the master device.

When the candidate master device is plural, the candidate master device may output first hint information for instructing a user to determine a master device among the candidate master devices. When the first device is included in the candidate master device, the first device may output a first hint information. And the first equipment responds to the operation that the user determines that the first equipment is the main equipment, and determines that the first equipment is the main equipment.

In the application, the multiple devices can negotiate to obtain the master device, or the user confirms the master device. The user confirms that the main equipment is the step needing user participation in the multi-equipment networking process, and the operation is simple.

The following describes a manner in which a first device transmits a first broadcast, transmits ultrasonic waves of a first frequency, and a second device transmits a response signal:

first, the first broadcast sent by the first device may include: an identification of the first device, a device type of the first device, and an identification for indicating the first frequency. The identification for indicating the first frequency may be, for example, the first frequency or a number of the first frequency. The identification indicating the first frequency characterizes the first broadcast transmitting the ultrasonic waves of the first frequency such that the second device can identify the ultrasonic waves transmitted by the first device among the received ultrasonic waves.

In this embodiment, when the second device receives the first broadcast and the first frequency ultrasonic wave, the second device may send a response signal to the first device, the response signal characterizing that the second device received the first broadcast and the first frequency ultrasonic wave. In this way, the first device may determine whether the first device and the second device are in the same room according to whether the second device transmits the response signal, where if the first device receives the response signal from the second device, the first device determines that the first device and the second device are in the same room, and if the first device does not receive the response signal from the second device, the first device determines that the first device and the second device are not in the same room.

In the embodiment of the application, the first device can be connected with the second device in the same room, and error connection can be avoided.

Second, the first broadcast sent by the first device may include: identification of the first device, device type of the first device. The second device may carry an identification in the response signal indicating said first frequency in order to characterize the reception of the ultrasonic wave by the second device. It will be appreciated that if the second device does not receive ultrasound, no identification indicating the first frequency is included in the response signal. In this way, the first device can determine whether the second device receives the ultrasonic wave of the first frequency, that is, whether the second device is in the same room as the first device, based on the response signal from the second device. In the embodiment of the application, the first device can be connected with the second device in the same room, and error connection can be avoided.

Third, the second device may respond to the first broadcast, the ultrasonic waves of the first frequency, respectively. In this implementation, the response signal includes: a first sub-signal and a second sub-signal. Wherein a first device may transmit a first broadcast and ultrasound at a first frequency, and when a second device receives the first broadcast, may transmit a first sub-signal to the first device, and correspondingly, the first device may receive the first sub-signal from the second device, the first sub-signal being indicative of the second device receiving the first broadcast. When a second device receives ultrasound waves at a first frequency, the second device may transmit a second sub-signal to the first device, and accordingly, the first device may receive the second sub-signal from the second device, the second sub-signal being indicative of the second device receiving ultrasound waves at the first frequency.

In one possible implementation, the first device may first transmit a first broadcast and when the second device receives the first broadcast, may transmit a first sub-signal to the first device. The first device may transmit ultrasonic waves of a first frequency in response to the first sub-signal, and the second device may transmit a second sub-signal to the first device when the second device receives the ultrasonic waves of the first frequency.

In this implementation, the first device may determine that the second device is co-located with the first device based on whether the first sub-signal and the second sub-signal are received from the second device. Wherein when the first device receives the first sub-signal and the second sub-signal from the second device, the first device may determine that the first device is co-located with the second device, and when the first device does not receive the first sub-signal or the second sub-signal from the second device, the first device may determine that the first device is not co-located with the second device. In the embodiment of the application, the first device can be connected with the second device in the same room, and error connection can be avoided.

It should be appreciated that after determining that the master device is the first device, the first device may broadcast the identification of the Wi-Fi direct channel, so that devices receiving the second broadcast may establish a connection with the first device, and in order to ensure the security of the wireless connection, in one possible implementation, after the first device establishes a connection with the second device, the first device may authenticate, and after the second device passes the authentication, the first device may establish an encrypted connection with the second device.

Wherein the authentication is used to determine whether the second device is a device that is responsive to the first broadcast and the ultrasound, the authentication is used to determine whether a preset personal identification PIN code in the second device and a preset PIN code in the first device are the same. And negotiating with the second device to obtain the first session key when the second device is a device responding to the first broadcast and the ultrasonic wave and the preset PIN code in the second device is the same as the preset PIN code in the first device.

In the implementation manner, the first device can improve the security of wireless connection between the first device and the second device through authentication and authorization of the second device. When the third device is included in the networking scene, the first device can authenticate and authenticate the second device and the third device in parallel, and the processing speed of authentication and authentication of the first device can be improved. The authentication and authentication of the third device by the first device may refer to the relevant description of the authentication and authentication of the second device by the first device.

In the implementation manner, the second equipment through authentication and authentication can establish encryption connection with the first equipment, so that the data transmission security between the first equipment and the second equipment can be ensured.

In one possible implementation, if any of the devices that have been networked fails, a new device may be replaced for networking.

For example, when a master fails, a new master may be replaced and the network may be re-established according to the networking method described above. For example, when a slave device fails, a new slave device may be replaced, which may be referred to as a third device, for example. The third device may transmit the first broadcast and the ultrasonic wave of the third frequency, and when the first device receives the first broadcast and the ultrasonic wave of the third frequency from the third device, may output second prompt information, where the second prompt information is used to instruct a user to confirm whether to connect the third device with the first device.

The first device may send the second broadcast in response to the user determining to connect the third device with the first device, where the second broadcast includes an identifier of the first device and an identifier of a Wi-Fi direct channel. The third device receives the second broadcast and may establish a connection with the first device over the Wi-Fi direct channel. After the first device establishes connection with the third device, negotiating with the third device to obtain a second session key, and the first device sends the connection information encrypted by the second session key to the third device, the third device can decrypt the connection information by using the first session key, and then establish encrypted connection with the first device according to the connection information.

In the implementation mode, any equipment in the networking equipment fails, and can replace new equipment without binding and selling, so that the maintenance cost is low.

In the method, a second device receives a first broadcast from a first device and ultrasonic waves of a first frequency, and sends a response signal to the first device; the second device negotiates with the first device, and when the first device is determined to be the main device, a second broadcast from the first device is received, wherein the second broadcast comprises: the identity of the first device, and the identity of the Wi-Fi direct channel. And the second device establishes connection with the first device on the Wi-Fi direct channel according to the identification of the first device and the identification of the Wi-Fi direct channel.

The second device negotiates with the first device to obtain a first session key, and receives encrypted connection information from the first device, where the connection information includes: service set identification SSID and password; and the second equipment decrypts the encrypted connection information by adopting the first session key to obtain the connection information, and establishes encrypted connection with the first equipment according to the connection information.

Detailed Description

Fig. 1 is a schematic diagram of a system architecture to which the present application is applicable. Fig. 1 illustrates an example of a sound box system constructed by a plurality of sound boxes. Referring to fig. 1, the system architecture includes a plurality of speakers, namely, a left speaker 11, a right speaker 12, a left surround speaker 13, a right surround speaker 14, and a subwoofer speaker 15. Wherein, left sound box 11, right sound box 12, left surround sound box 13, right surround sound box 14, and subwoofer sound box 15 can be through wireless connection constitution audio amplifier system. It should be understood that the types and numbers of sound boxes in fig. 1 are exemplary, and do not constitute any limitation on the system architecture applicable to the embodiments of the present application.

In the sound box system, each sound box can output the audio of different sound channels according to the performance of the sound box system, so that the audio output by the sound box system can achieve a stereo effect. For example, if left speaker 11 may output left channel audio, right speaker 12 may output right channel audio, left surround speaker 13 may output left surround audio, right surround speaker 14 may output right surround audio, and subwoofer speaker 15 may output bass channel audio, so that a user may hear audio with a stereo effect.

Wherein, a plurality of audio amplifier constitution audio amplifier system's key one step is: a plurality of sound boxes are connected through wireless to form a network. In one embodiment, a user may sequentially perform network configuration on a plurality of speakers on a terminal, so that each speaker is connected to the same lan, that is, the plurality of speakers form a network through wireless connection, and the plurality of speakers form a speaker system. For example, a user may first allocate a first sound box to a network in an Application (APP) of the terminal, then add a second sound box, and allocate the second sound box to the network until the allocation of a plurality of sound boxes is completed. It should be understood that each speaker accessing the same lan can be understood as: each speaker is connected to the same Access Point (AP), for example, the AP may be a router.

However, the mode requires users to sequentially distribute the network to a plurality of sound boxes, the operation is complex, the network distribution time is long, the efficiency is low, and the sound boxes need to be connected to the same local area network by relying on the same AP.

In one embodiment, the roles of each speaker may be preset during the manufacturing process of the speakers, and the keys may be preset in each speaker. The roles of the speakers are preset, for example, the left speaker 11 is set as a master speaker, and the other speakers are set as slave speakers. When the multi-sound box is in wireless connection, based on a preset role, the slave sound box can be connected into the master sound box according to the secret key by adopting connection modes such as a wireless loudspeaker, audio (wireless speaker and audio, WISA) and the like, so that the wireless connection of the multi-sound box is realized.

In this embodiment, because the role and the key of each speaker are preset, the plurality of speakers need to be sold in a set, and maintenance cost is high.

Therefore, a networking method with wide application range and high speed and safety is needed to realize wireless connection of a plurality of sound boxes. The networking method provided by the embodiment of the application does not depend on an AP (e.g. a router), does not need to preset roles and keys of the sound boxes, but negotiates among the sound boxes to establish wireless connection, so that the networking efficiency is high, any sound box can be replaced after being failed, the application range is wide, and the maintenance cost is low. It should be appreciated that the multi-device group list features in embodiments of the present application: the multiple devices are connected wirelessly to form a network.

Speaker 20 may establish Wi-Fi channels with other devices through Wi-Fi chip 26 and antenna 28 to enable Wi-Fi communications. In one embodiment, the Bluetooth chip 25 and the Wi-Fi chip 26 may share an antenna 28, or the Bluetooth chip 25 and the Wi-Fi chip 26 may each correspond to a separate antenna 28. It should be appreciated that the bluetooth chip 25 and Wi-Fi chip 26 are illustrated in fig. 2 as sharing an antenna 28.

Processor 27 may be configured to execute S301 to S314 in the following embodiments to complete the multi-speaker networking.

In one embodiment, processor 27 may include: the device comprises an ultrasonic detection module, a user interaction module, a device discovery module, a networking management module, an authentication module and a connection management module. Wherein the name of each module in the processor 27 is given by way of example, wherein some modules (or all modules) may be integrated into a single body.

The user interaction module is used for managing the keys 21, the indicator lights 22, the microphone 23 and the loudspeaker 24. For example, the user interaction module may detect the user's operation of the key 21 and collect sound through the microphone 23. In addition, the user interaction module may control the indicator lamp 23 to flash, display different colors, and the like, and the user interaction module may also control the speaker 24 to play audio.

And the equipment discovery module is used for discovering other sound boxes which are the basis for networking with the other sound boxes. In one embodiment, the device discovery module may discover other speakers by using bluetooth broadcast or Wi-Fi broadcast to network with other speakers. For example, the device discovery module may send Wi-Fi probe frames (Wi-Fi probes) to discover other speakers. In one embodiment, the device discovery module may perform S301-S308 in the embodiments described below.

In one embodiment, an Ultra Wide Band (UWB) tag may also be disposed on the speaker 20, and the device discovery module may use UWB technology to discover other speakers.

And the ultrasonic detection module is used for transmitting ultrasonic waves and detecting ultrasonic waves transmitted by other sound boxes.

In one embodiment, the device discovery module is further configured to detect whether other speakers are in the same room (same room) as the speaker according to the emitted ultrasonic waves, and further perform networking with the speakers in the same room.

And the authentication module is used for authenticating and authenticating other sound boxes. In one embodiment, the authentication module may perform S309-S310 in the following embodiments.

In one embodiment, after the speakers discover other speakers, they may be interconnected through a communication network to enable interaction of wireless signals. The communication network may be, but is not limited to: wi-Fi hotspot networks, wi-Fi peer-to-peer (P2P) networks, WISA networks, and the like. Wi-Fi point-to-point connections can also be referred to as Wi-Fi direct (Wi-Fi direct).

The following embodiments are described by taking the connection between sound boxes through Wi-Fi point-to-point connection as an example. In such an embodiment, the connection management module is configured to manage Wi-Fi P2P layers, such as start and stop of Group Owners (GO), and the like. And the connection management module is also used for establishing a physical channel for authentication by the authentication module, establishing a subsequent service channel and managing service connection. In one embodiment, the connection management module may perform S311-S314 in the embodiments described below.

The networking management module can be understood as a central management module and is used for managing the ultrasonic detection module, the user interaction module, the equipment discovery module, the authentication module and the connection management module. For example, after the loudspeaker box discovers other loudspeaker boxes, the networking management module can call the ultrasonic detection module to complete detection in the same room, and screen the loudspeaker boxes in the same room. When the screened sound boxes meet networking requirements, the user interaction module can be triggered to remind the user, so that the user can confirm the main sound box. After the user confirms the main sound box, the networking management module invokes the authentication module to finish the authentication and the authentication of the sound box according to the main equipment confirmed by the user. After passing the authentication and the authentication, the networking management module calls the connection management module to complete the wireless network connection of each sound box, namely, the sound box networking is completed.

Fig. 3 is a flow chart of an embodiment of a networking method according to an embodiment of the present application. Referring to fig. 3, the networking method provided in the embodiment of the present application may include:

s301, the first device transmits a first bluetooth broadcast.

When multiple devices are networked, the user may turn on each device and turn on each device's bluetooth functionality, as well as wireless local area network (wireless local area network, WLAN) functionality. Each device may perform steps S301-S305, where the steps performed by each device are illustrated with respect to the first device.

After the first device turns on the bluetooth function, a bluetooth scan (e.g., bluetooth low energy (bluetooth low energy, BLE) scan) may be performed and the first bluetooth broadcast from the other devices is listened to. The first device may transmit a first bluetooth broadcast on an inquiry scan channel (inquiry scan channel). In one embodiment, the first device may transmit the first Wi-Fi broadcast when the first device transmits the Wi-Fi broadcast discovery device. Wherein the first broadcast includes: the first bluetooth broadcast or the first Wi-Fi broadcast is taken as an example for explanation in the embodiment of the present application.

The first bluetooth broadcast is used to discover other devices around the first device. For example, other devices surrounding the first device may respond to the first bluetooth broadcast when receiving the first bluetooth broadcast. The first device receives the response signals of the other devices, and can determine that the other devices exist around the first device, namely, find the other devices.

Similarly, the first device may also listen for a first bluetooth broadcast from the other device on the inquiry scan channel in response to the first bluetooth broadcast from the other device.

In one embodiment, the first bluetooth broadcast may include: the identity of the first device and the device type of the first device.

S302, the first device transmits ultrasonic waves.

It should be understood that S302 and S301 may be performed simultaneously, without distinction of the order of the two.

The purpose of the first device emitting ultrasound waves is: screening out devices in the same room as the first device. Because the ultrasonic waves are reflected when encountering obstacles during transmission in the air, the ultrasonic waves cannot pass through the wall, and the device which is in the same room as the first device can receive the ultrasonic waves emitted by the first device, but the device which is not in the same room as the first device cannot receive the ultrasonic waves emitted by the first device.

In one embodiment, the frequency of the ultrasonic waves emitted by each device may be different so that the device receiving the ultrasonic waves may distinguish between the devices emitting the ultrasonic waves. For example, the first device may emit ultrasonic waves at a first frequency.

S303, the second device transmits a response signal to the first device.

After the second device turns on the bluetooth function, bluetooth scanning may be performed and first bluetooth broadcasts from other devices are monitored.

In one embodiment, the first bluetooth broadcast may further include: an identification of the frequency of the ultrasonic wave transmitted by the first device, such as the identification may be a first frequency. In this embodiment, if the second device is in the same room as the first device, the second device may receive the ultrasonic wave emitted by the first device and may acquire the frequency of the ultrasonic wave. When the second device monitors the first bluetooth broadcast and receives the ultrasonic wave of the first frequency, the second device may send a response signal to the first device. The response signal characterizes the second device receiving a first broadcast from the first device and an ultrasonic wave at a first frequency. In such an embodiment, the response signal may include: the identity of the second device and the device type of the second device.

The identifier of the second device may be a name, a model number, etc. of the second device. The device type of the second device may be, for example: sound boxes, mobile phones, watches, etc. For example, when the device type of the second device is a speaker, the device type of the second device is also used to indicate a specific speaker class, e.g., the type of the speaker may be a left speaker, a right speaker, etc. That is, when the second device is another type of device, the device type of the second device is also used to indicate the specific type of device.

In one embodiment, the first bluetooth broadcast may not include: the identification of the frequency of the ultrasonic wave transmitted by the first device, when the second device monitors the first bluetooth broadcast and receives the ultrasonic wave of the first frequency, may send a response signal to the first device, in which embodiment the response signal may include: an identification of the second device, a device type of the second device, and an identification for indicating that the second device received the ultrasonic wave of the first frequency. In one embodiment, the identification for indicating that the second device received the ultrasonic wave of the first frequency may be: identification of the first frequency, such as the first frequency.

In one embodiment, the second device, upon receiving the first bluetooth broadcast and the ultrasonic wave at the first frequency, may send a signal (e.g., a first sub-signal and a second sub-signal), respectively, to the first device to characterize that the second device received the first bluetooth broadcast and the ultrasonic wave at the first frequency, respectively. Wherein the response signal may comprise a first sub-signal and a second sub-signal. In such an embodiment, the identification of the first frequency may or may not be included in the first bluetooth broadcast.

In such an embodiment, when the second device monitors the first bluetooth broadcast, a first sub-signal may be transmitted to the first device, the first sub-signal characterizing that the second device received the first bluetooth broadcast. The first sub-signal includes: the identity of the second device and the device type of the second device. The first device may transmit ultrasonic waves at a first frequency in response to receiving the first sub-signal from the second device. If the second device receives ultrasonic waves of the first frequency, a second sub-signal may be sent to the first device, the second sub-signal being used to characterize the reception of ultrasonic waves of the first frequency by the second device.

Wherein when the first bluetooth broadcast includes the identification of the first frequency, the identification of the second device and the device type of the second device may be included in the second sub-signal. When the first bluetooth broadcast does not include the identification of the first frequency, the second sub-signal may include: an identification of the second device, a device type of the second device, and an identification for indicating that the second device received the ultrasonic wave of the first frequency.

In one embodiment, the second device is unable to receive the ultrasonic waves of the first frequency transmitted by the first device if the second device is not co-located with the first device. In this embodiment, the response signal may include: the identity of the second device and the device type of the second device.

In one embodiment, the first device may also measure the distance between the second device and the first device in other ranging manners, and the first device may detect whether the first device and the second device are in the same room according to the distance between the second device and the first device. Wherein the first device may determine that the second device is co-located with the first device when the distance of the second device from the first device is less than or equal to a preset distance. When the distance between the second device and the first device is greater than the preset distance, the first device may determine that the second device is not co-located with the first device. Among them, ranging means may include, but are not limited to: infrared ranging, bluetooth ranging, etc.

The following embodiments will be described by taking the example that the second device and the first device are in the same room.

It should be appreciated that the interaction flow between the first device and the third device is also illustrated in fig. 3, and the interaction flow between the first device and the third device may refer to the interaction flow between the first device and the second device. In fig. 3, the third device is illustrated as being in the same room as the first device.

S304, the first device determines the devices to be networked according to the response signals from the devices.

After the first device transmits the first bluetooth broadcast, other devices with bluetooth functions turned on around the first device may respond to the first bluetooth broadcast, so that the first device may receive response signals from the plurality of devices. For example, the plurality of devices may include a second device, a third device, and a fourth device, which is described below as being not co-located with the first device.

And the first equipment determines equipment to be networked according to the response signals from the equipment. In one embodiment, the first device may use the device that sent the response signal and is in the same room as the first device as the device to be networked.

In one embodiment, since the device that "receives both the first broadcast signal from the first device and the ultrasonic wave of the first frequency" can transmit the response signal to the first device, the first device can determine that the device transmitting the response signal is in the same room as the first device, and thus can use the device transmitting the response signal as the device to be networked.

In an embodiment, because the device detecting the ultrasonic wave of the first frequency may carry an identification for indicating that the second device receives the ultrasonic wave of the first frequency in the response signal, the first device may further determine the device to be networked according to the received response signal.

For example, the first device may receive response signals from the second device, the third device, and the fourth device, and thus may determine that the second device, the third device, and the fourth device may each listen to the first broadcast signal. In addition, the first device may further detect a response signal from the second device, a response signal from the third device, and whether the response signal of the fourth device includes "an identifier for indicating that the ultrasonic wave of the first frequency is detected", and determine whether the second device, the third device, and the fourth device are in the same room as the first device.

For example, the response signal from the second device and the response signal from the third device each include a "first frequency", but the response signal from the fourth device does not include a "first frequency", the first device may determine that the second device and the third device are co-located with the first device, and the fourth device is not co-located with the first device. In this way, the first device may use the first device, the second device, and the third device as devices to be networked.

In the embodiment of the application, the first device sends the response signal and is in the same room as the first device, so that the first device can be prevented from being connected with other devices in other families or other environments in a wireless manner, erroneous connection can be avoided, and networking accuracy is improved.

The following description will take the first device, the second device, and the third device as devices to be networked as examples.

S305, the first device, the second device and the third device negotiate to determine candidate master devices.

The first device, the second device, and the third device negotiate to determine a candidate master device for purposes of: and determining roles of the first device, the second device and the third device, so that the first device, the second device and the third device can be connected in a wireless mode according to the roles of the first device, the second device and the third device. Roles may include master and slave. The master device is included in devices to be networked, and devices other than the master device in the devices to be networked may be referred to as slave devices. And the master device is used for establishing a communication channel with the slave device so as to support service data transmission. In one embodiment, the candidate master device may be a device with high processing power among the devices to be networked.

After the first device determines the device to be networked, the first candidate master device may be determined according to the device types of the first device, the second device, and the third device, and the first candidate master device may be at least one. For example, the first device is taken as a left sound box, the second device is taken as a right sound box, and the third device is taken as a subwoofer sound box for illustration, because the left sound box and the right sound box have strong processing capability, the first device can determine the left sound box (first device) and the right sound box (second device) as first candidate main devices.

In one embodiment, after the first device determines the first candidate master device, the identification of the first candidate master device may be synchronized with the second device and the third device, where the identification of the first candidate master device includes: the identification of the left sound box and the identification of the right sound box. Similarly, the first device may also receive the identification of the second candidate master device determined by the second device, and the identification of the third candidate master device determined by the third device. That is, the first device may receive the identification of the candidate master device determined by the other devices.

The first device may determine the candidate master device according to the first candidate master device, the second candidate master device, and the third candidate master device.

For example, the first device may consider a device included in each of the first candidate master, the second candidate master, and the third candidate master as a candidate master. Alternatively, the first device may use the first N devices having the largest number of occurrences among the first candidate master device, the second candidate master device, and the third candidate master device as candidate master devices. N is an integer greater than or equal to 1.

For example, the first device, the second device, and the third device may also determine the candidate master device using the same determination rule, so that the candidate master devices determined by the first device, the second device, and the third device may be the same, e.g., the first candidate master device, the second candidate master device, and the third candidate master device may be the same, and the first device may use the first candidate master device as the candidate master device.

The candidate master device including the first device and the second device is described below as an example.

And S306, outputting prompt information by the candidate master device, wherein the prompt information is used for prompting a user to select the master device.

In one embodiment, the hint information output by the candidate host device may be referred to as a first hint information.

The step S305 teaches that the first device may determine the candidate master device, and similarly, the second device, and the third device may also determine the candidate master device, because the candidate master devices determined by the first device, the second device, and the third device are the same using the same determination rule. Because each device may determine a candidate master device, the device determined to be a candidate master device may output a hint message to characterize itself as a candidate master device.

In one embodiment, after the candidate masters determined by the first device, the second device and the third device, the candidate masters determined by the first device, the second device and the third device may be synchronized with each other, and when the candidate masters are consistent, the candidate masters may output a prompt message.

In fig. 3, the candidate master device includes a first device and a second device, for example, if the first device and the second device can both determine that the candidate master device is the first device and the second device, the first device and the second device can both output prompt information. The prompting information is used for prompting a user to select the main equipment.

In one embodiment, taking the first device as an example, the first device may output the prompt information in a voice manner, for example, the first device may play "press a key on a sound box, and determine the master device of the networking. Or, in order to make it easier for the user to see which devices output the prompt information more clearly, the first device may also control the indicator light on the first device to flash or display different colors, so that the user can quickly determine the candidate master device, so as to select the master device from the candidate master devices.

In one embodiment, when the first device includes a display screen, the first device may also display a prompt message on the display screen. The method for outputting the prompt information by the candidate master device is not limited.

In one embodiment, the first device, the second device, and the third device may negotiate to determine the master device without user confirmation.

S307, in response to the user confirming the operation of the main device, the main device sends a second Bluetooth broadcast, wherein the second Bluetooth broadcast comprises the GO name and the identification of the Wi-Fi P2P channel.

In one embodiment, the first device may also broadcast the GO name and Wi-Fi P2P by sending a Wi-Fi broadcast, in which the master device may send a second Wi-Fi broadcast in response to the user confirming operation of the master device. The second bluetooth broadcast and the second Wi-Fi broadcast may be referred to as a second broadcast, and in this embodiment of the present application, the second broadcast is taken as an example of the second bluetooth broadcast.

In fig. 3, the user is shown as an example of confirming the first device as the master device. For example, the user may press a key on the first device confirming that the first device is the master device.

The first device may send a second bluetooth broadcast in response to the user confirming operation of the master device, such as the first device detecting operation of a user pressing a key on the first device. The second bluetooth broadcast is used to establish a Wi-Fi P2P connection with the slave device. In one embodiment, the second bluetooth broadcast may include: GO name, and identification of Wi-Fi P2P channel. The GO is the primary device, i.e., the first device, and the GO name may be referred to as the identity of the first device.

Wherein, the GO name can be: a service set identification (service set identifier, SSID), or a media access control address (media access control address, MAC) of the master device (first device). The second device, the third device, among the devices to be networked, except the GO may be referred to as a Group Client (GC). The identification of Wi-Fi P2P channels may be: channel number, or frequency band in which the channel is located, etc.

S308, the second device establishes a connection with the first device on the Wi-Fi P2P channel.

Similarly, the third device may also establish a connection with the first device over the Wi-Fi P2P channel.

The second device monitors the bluetooth broadcast in the inquiry scanning channel, and can monitor the second bluetooth broadcast, so that the GO name and the identification of the Wi-Fi P2P channel can be obtained. The second device may establish a connection with the first device on the W-iFi P2P channel according to the GO name.

In one embodiment, the second device may feed back a connection response message to the first device in the Wi-Fi P2P channel in response to listening to the second bluetooth broadcast, characterizing that the second device establishes a temporary connection with the first device over the Wi-Fi P2P channel. It should be appreciated that Wi-Fi P2P channels may be referred to simply as P2P channels. In one embodiment, the process by which the second device may establish a connection with the first device over the Wi-Fi P2P channel may be described with reference to the associated description in the Wi-Fi P2P protocol.

S309, the first device authenticates the second device.

When the first equipment authenticates and authenticates the second equipment, the third equipment can be authenticated and authenticated in parallel, and therefore authentication and authentication efficiency is improved.

Taking the first device authenticating the second device as an example, the first device authenticating the second device can be understood as: the first device determines whether the second device is a device in the device to be networked, and when the second device is determined to be the device in the device to be networked, authentication passes, and authentication operation can be performed.

The authentication process comprises the following steps: in one embodiment, in response to the second bluetooth broadcast, when the second device feeds back a connection response message in the Wi-Fi P2P channel, the connection response message may include: and the identifier is used for indicating the second equipment to be the equipment in the equipment to be networked. For example, the connection response message may include an identifier of the second device, or other identifiers for indicating that the second device is included in the device to be networked, where a value of the flag bit is 1 indicates that the second device is included in the device to be networked. The first device may determine, according to the connection response message, whether the second device is included in the device to be networked.

Authentication process: in one embodiment, the first device and the second device each have stored therein a preset key, such as a personal identification (personal identification number, PIN) code. The first device authenticating the second device can be understood as: the first device determines whether the preset PIN in the second device is the same as the preset PIN code in the first device.

The second device may send the encrypted preset PIN code in the second device to the first device by using an encryption algorithm, and after the first device decrypts the preset PIN code in the second device, if it is determined that the preset PIN code in the second device is the same as the preset PIN code in the first device, the second device authenticates the second device, and if the preset PIN code in the second device is different from the preset PIN code in the first device, the second device authenticates the second device.

In one embodiment, the first device may also employ a simple cryptographic exponential key exchange (simple password authenticated exponential key exchange, SPEKE) algorithm to determine whether the preset PIN code in the second device is the same as the preset PIN code in the first device.

And S310, when the second device passes authentication and the authentication passes, the first device and the second device negotiate to obtain a first session key.

A session key for encrypting and decrypting data transmitted between two devices. It should be noted that the first device and the second device negotiate to obtain a first session key and similarly the first device and the third device negotiate to obtain a second session key, the first session key and the second session key being different. In this way, the session key between each group client GC and the group owner GO is different, which can improve data security.

In one embodiment, the first device and the second device may negotiate a first session key using a SPEKE algorithm when the second device authenticates and the authentication passes. Wherein the SPEKE algorithm comprises two phases, a key exchange phase and a key authentication phase. In the key exchange stage, the first device and the second device obtain a session key through negotiation, in the key authentication stage, the first device and the second device mutually confirm the session key known by the opposite side, and when the session key known by the opposite side is confirmed to be consistent, the session key can be used as the first session key.

The second device can access the encrypted GO (first device) on the Wi-Fi P2P channel by adopting the SSID and the password, i.e. the second device establishes an encrypted connection with the first device. Thus, the first device and the second device can transmit encrypted data on an unencrypted channel, and the security of data transmission is ensured.

Similarly, the first device may encrypt the connection information using the second session key to obtain second connection information, and send the second connection information to the third device on the Wi-Fi P2P channel. And the third device decrypts the second connection information by using the second session key to obtain the connection information, and the third device can obtain the SSID and the password if decrypting. The third device may access an encrypted GO (first device) on a Wi-Fi P2P channel using an SSID and password. Thus, the first device and the third device can transmit encrypted data on an unencrypted channel, and the security of data transmission can be ensured.

The second device and the third device respectively establish encryption connection with the first device, namely the first device, the second device and the third device complete networking. After the first device, the second device and the third device are networked, the first device can respectively transmit service data to the second device and the third device through Wi-Fi P2P channels, so that smooth execution of the service is ensured. For example, after the speakers shown in fig. 1 are networked, the first device (such as a left speaker) may send audio data to other speakers on the Wi-Fi P2P channel, and multiple speakers may play audio, so that the user may hear the audio with a stereo effect.

Fig. 4 is a schematic diagram of a speaker networking provided in an embodiment of the present application. Referring to a in fig. 4, after a user turns on a sound box, and turns on a bluetooth function and a WLAN function of the sound box, each sound box may transmit a first bluetooth broadcast and an ultrasonic wave. Note that the frequencies of the ultrasonic waves transmitted from different sound boxes are different, and the frequencies of the ultrasonic waves are not shown in a in fig. 4. After each sound box executes S301-S305, if the determined candidate main devices are the left sound box and the right sound box, the indicator lights of the left sound box and the right sound box flash or display different colors, and play the prompt information such as "press the key on the sound box, determine the main device of the networking", as shown in b in fig. 4. Referring to b in fig. 4, if the user presses a key on the left speaker, the left speaker may determine that the user is the master device, and perform S307-S314 to wirelessly connect with each speaker to complete the networking.

Fig. 5 is another schematic diagram of a speaker networking provided in an embodiment of the present application. Referring to fig. 5, the process of speaker networking may be divided into four stages, namely: a device discovery phase, a temporary connection phase, an authentication and authorization phase and a service network establishment phase.

In the device discovery stage, the sound box starts BLE scanning, can send BLE broadcasting, emit ultrasonic waves and start ultrasonic detection. The device discovery phase may determine the speakers to be networked and determine the master speakers. The master soundbox may disclose the GO name and identification of the Wi-Fi P2P channel through the bluetooth channel. In one embodiment, the device discovery phase may include S301-S307.

And in the temporary connection stage, the slave sound box establishes connection with the master sound box through a Wi-Fi P2P channel to complete the establishment of a Wi-Fi P2P physical link, namely, establish the Wi-Fi P2P channel. In one embodiment, the temporary connection phase may include S308.

In the authentication and authorization stage, the master loudspeaker box can perform authentication and authorization on each slave loudspeaker box in parallel and negotiate a session key. In one embodiment, the temporary connection phase may include S309-S310.

In the service network establishment stage, the master sound box can encrypt the connection information, and the encrypted connection information is transmitted to each slave sound box on the non-encrypted Wi-Fi P2P channel, so that each sound box can establish encrypted connection with the master sound box to complete networking. In one embodiment, the service network establishment phase may include S311-S314.

The networking flow shown in fig. 3 to 5 is a flow when a plurality of devices are first networked. Taking the sound box as an example, it is understood that after each sound box is first networked, each slave sound box can directly access the encrypted master sound box on the Wi-Fi P2P channel by adopting SSID and password when each sound box is electrified next time, so that networking is completed.

In the embodiment of the application, when a plurality of devices are networked, the devices can determine the device to be networked by combining the device discovery with ultrasonic detection, the device to be networked can determine candidate master devices, and the master devices are determined by means of participation of users. After determining the master device, the master device may establish a temporary connection with the slave devices, and after the master device concurrently authenticates and authenticates each slave device, the master device may negotiate a session key, and further transmit encrypted data over the wireless channel, so that the slave device establishes an encrypted connection with the master device to complete networking. The networking process of a plurality of devices only needs to confirm the main device by a user, the operation is simple, the networking efficiency is high, the devices can be connected with each other, the same router is not needed, and the application range is wide. In addition, any equipment fails, can be replaced in time, and has low maintenance cost.

In one embodiment, after any of the speakers fails, the user may purchase the same type of speaker, trigger a new speaker and a networked speaker to be restored, or trigger a new speaker to be added to the networked speaker.

If the main sound box (such as the left sound box) fails, the user can purchase a new left sound box, and the user can restore other sound boxes to factory settings, such as the user restores the bass sound box, the right sound box, the left surrounding sound box and the right surrounding sound box to factory settings. Alternatively, the user may operate (e.g., key) on other speakers to trigger the other speakers to reenter the group network state. After the other sound boxes are restored to the factory setting or re-enter the networking state, the other sound boxes can be re-networked with the newly purchased left sound box according to the flow in fig. 3.

If the slave loudspeaker box fails, the slave loudspeaker box is a bass loudspeaker box, a user can purchase a new bass loudspeaker box, and the Bluetooth function and the WLAN function of the bass loudspeaker box are opened, so that the bass loudspeaker box can send first Bluetooth broadcasting and ultrasonic waves. The main sound box monitors the first Bluetooth broadcast from the subwoofer sound box, and can output second prompt information to prompt a user whether to add the scanned subwoofer sound box into the networking, namely prompt the user to confirm whether to connect the subwoofer sound box with the main sound box. If the main speaker detects that the user agrees to connect the subwoofer speaker with the main speaker, S307-S314 may be executed to add a new subwoofer speaker to the networking. In one embodiment, the new subwoofer enclosure may be referred to as a third device, and the frequency of the ultrasonic waves emitted by the third device is a third frequency.

In the embodiment of the application, any one of the networked devices fails, a user can timely replace new devices, and the multi-device networking is triggered, so that the operation is simple and convenient, and the use of the user is not affected.
