Referring to fig. 1, one of flowcharts of a device connection method provided in an embodiment of the present invention is shown. The method is applied to an electronic device, and the electronic device described in the embodiment of the present invention may include a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, a pedometer, and a fixed terminal such as a Digital TV, a desktop computer, and the like.
The equipment connection method specifically comprises the following steps:
In the embodiment of the invention, the electronic device is a master device for initiating the Bluetooth connection, and the other devices are slave devices for receiving the Bluetooth connection.
The electronic device may be a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, an intelligent bracelet, a pedometer, etc. having a bluetooth function, and a fixed terminal such as a Digital TV, a desktop computer, etc.; the electronic device may also be a digital device such as a digital camera, a digital video camera, or the like; or an electronic wallet and an electronic lock which are formed by the Bluetooth technology, or traditional household appliances such as a microwave oven, a washing machine, a refrigerator, an air conditioner and the like which are embedded into a Bluetooth system; the other devices may be peripheral devices of electronic devices such as a bluetooth headset, a bluetooth sound box, a mouse, a keyboard, a speaker, and the like, or any one of the electronic devices.
In this document, taking an electronic device as a mobile terminal and other devices as earphones as examples, the detailed description of the embodiments of the present invention is given, and the case where the electronic device and the other devices are other objects, or the case where the electronic device is an earphone and the other devices are mobile terminals is also applicable to the scheme of the present application, and the reference may be made to the implementation.
First, the bluetooth connection between the electronic device and other devices in the prior art generally requires the following steps:
step S1: the electronic equipment pages other equipment in a frequency hopping mode, the other equipment scans external paging at fixed intervals, and when the external paging is scanned, the paging is responded and paired; extracting clock components from the received information code stream by two parties, and carrying out clock synchronization; exchanging related parameters of ACL (Asynchronous connection loss) connection, supporting the Bluetooth feature by the two parties, and finally establishing ACL connection.
Step S2: the electronic device initiates a connection request of a channel, acquires a2dp (advanced audio distribution Profile, advanced audio transmission Protocol) and hfp (Hands Free Profile) related information supported by other devices through sdp (service discovery Profile, service discovery Protocol), and sends a channel id (signaling channel identifier) used this time and its own related connection layer or application layer Protocol information to other devices, and finally establishes a connection of L2CAP (Logical Link Control and Adaptation Protocol).
Step S3: the electronic equipment adopts SDP (Service Discovery protocol) to inquire the hands-free Service of other equipment, obtains the channel number of rfcom (serial port simulation protocol), and then initiates the connection request of the rfcom to establish the connection of the rfcom.
The above process may be represented as a link estimate (link establishment), channel estimate (channel establishment), rfcomm estimate (serial port simulation protocol establishment), and connection (connection).
The inventor has found that, in the above steps S1, S2, and S3, except for the step of paging other devices and performing clock synchronization by using a frequency hopping method in step S1 and the step of transmitting the channel id information used this time in step S2, all the other connection procedures are protocol information supported by the electronic device and the other devices during exchange, and the protocol information is information inherent to the electronic device and the other devices and does not change due to the connection scenario between the two devices. Therefore, in the embodiment of the present invention, when the electronic device pages another device in a frequency hopping manner, the other device responds to the page and performs pairing when scanning the page of the electronic device, and after the two devices perform clock synchronization, the electronic device detects an ACL and bluetooth connection instruction sent by the electronic device and the other device to be paired. The historical connection record is pre-recorded during the process that the electronic equipment and other equipment establish the Bluetooth connection in advance.
Optionally, the historical connection record is pre-recorded by the following steps a 1-a 2:
step A1, acquiring parameter information in the connection process under the condition that the electronic equipment and the other equipment establish successful connection by exchanging information of both sides; the parameter information includes fixed parameter information and dynamic parameter information, and the fixed parameter information at least includes: asynchronous connectionless parameter information, logical link control and adaptation protocol parameter information, serial port simulation protocol parameter information, and connection timing sequence information.
In the embodiment of the present invention, when the electronic device and the other device establish a connection for the first time, the bluetooth connection is established through the above steps S1 to S3, and after the connection is established, the electronic device serving as the main device records and stores information acquired in the process of exchanging information between the two devices as parameter information. In order to ensure that the historical connection record is not changed by the user, the electronic device may set corresponding read-write permission for the historical connection record.
Specifically, the parameter information includes fixed parameter information that does not change in each connection of the electronic device and the other device and dynamic parameter information that changes in each connection. The fixed parameter information at least comprises parameter information for establishing ACL (asynchronous connectionless) connection between the electronic equipment and other equipment, parameter information for establishing L2CAP (logical link control and adaptation protocol) connection, parameter information for establishing rfcomm (serial port simulation protocol) connection and connection timing sequence information. The ACL parameter information at least comprises the support condition of the electronic equipment and other equipment for Bluetooth feature, such as the setting of time-out, whether the role switching between an active initiator and a passive receiver can be performed, whether a link can enter a sleep mode and the like; the L2CAP parameter information includes at least: input/output MTU (Maximum Transmission Unit), input/output stream and error control information, input/output FCS (Frame Check Sequence), input/output Frame format information, and the like; the rfcomm parameter information includes at least: general control parameters of the simulation serial port, port parameter setting information and the like; the connection timing information indicates which of the electronic device and the other device initiates a connection request and which responds to the request. In the embodiment of the invention, the electronic equipment sends a connection request to other equipment, the other equipment responds to the connection request, and the electronic equipment is used as main equipment to record corresponding parameter information; conversely, in other embodiments, the other device may also send a connection request to the electronic device, and the electronic device responds to the connection request, and the other device records the corresponding parameter information as the master device.
In addition, the parameter information also includes dynamic parameter information. The dynamic parameter information is information that may dynamically change in each connection, and includes at least channel id (signaling channel identifier) information. The channel ID is parameter information during L2DAP connection, the end point of a signaling channel is represented by a channel mark channel ID, 65536 channels can exist in an ACL link at most, the channels comprise a signaling channel and a data channel, the data channel is established through the signaling channel, and then the data channel transmits data. The channeld here refers to a signaling channel.
Step A2, storing the parameter information as a history connection record in the electronic device.
After the connection is established, the electronic device serving as the main device stores the parameter information as a historical connection record. In order to ensure that the historical connection record is not changed by the user, the electronic device may set corresponding read-write permission for the historical connection record.
And 102, acquiring historical parameter information from the historical connection record.
In the embodiment of the invention, the electronic device searches the historical connection record when being connected with other devices before in the memory, and if the historical connection record exists, the electronic device indicates that the electronic device and other devices have successfully performed Bluetooth connection previously, and the electronic device has recorded the parameter information of the electronic device and other devices. At this time, parameter information may be acquired from the historical connection record, and the parameter information may include fixed parameter information and dynamic parameter information.
If there is no historical connection record, it indicates that the electronic device and the other device have not previously performed bluetooth connection, and a method of exchanging information of both parties, that is, the method of step S1-step S3, may be adopted to establish bluetooth connection. And after the connection is successful, recording the parameter information of the connection, and storing the parameter information as historical parameter information of the electronic equipment and other equipment in the electronic equipment for the next connection.
And 103, generating the current parameter information according to the historical parameter information and the dynamic parameter information corresponding to the current connection request.
In the embodiment of the invention, the information which can be dynamically changed in each connection is regenerated to obtain the dynamic parameter information. And updating the corresponding information in the historical parameter information by using the dynamic parameter information to obtain the current parameter information.
Compared with the prior art that the parameter information is obtained by exchanging information between two parties for multiple times, the embodiment of the invention directly obtains the historical connection information from the historical connection record, regenerates the dynamic parameter information, and updates the historical connection information by using the dynamic parameter information to obtain the connection information. Because the dynamic parameter information only occupies a small proportion of the parameter information, the time consumption for generating the dynamic parameter information is less, and other fixed parameter information is directly acquired through the historical connection record, so that the time consumed by Bluetooth connection is greatly reduced.
And 104, establishing connection with the other equipment by using the parameter information.
In the embodiment of the invention, the current parameter information, namely the historical parameter information and the dynamic parameter information is utilized to establish ACL connection, L2CAP connection and rfcomm connection with other equipment in sequence, and finally the Bluetooth connection is successfully established.
In summary, in the embodiment of the present invention, a historical connection record with other devices is obtained; acquiring historical parameter information from the historical connection records; generating current parameter information according to the historical parameter information and the dynamic parameter information corresponding to the current connection request; and establishing connection with the other equipment by using the parameter information. In the method, the electronic equipment establishes Bluetooth connection with other equipment according to the dynamic parameter information and the historical parameter information, and the electronic equipment reduces the information exchange times with other equipment by using the pre-recorded historical parameter information, so that the Bluetooth connection speed is increased, and the efficiency of using the Bluetooth function by a user is improved.
Referring to fig. 2, a second flowchart of a device connection method provided in the embodiment of the present invention is shown, where the method is applied to an electronic device, and specifically may include the following steps.
In the embodiment of the present invention, step 201 may refer to step 101, which is not described herein again.
In the embodiment of the present invention, step 202 may refer to step 102, which is not described herein again.
In the embodiment of the present invention, after acquiring the historical parameter information, the electronic device needs to regenerate the dynamic parameter information, so as to update the corresponding information in the historical parameter information according to the dynamic parameter information. In the normal bluetooth connection process, the dynamic parameter information that may be dynamically changed in each connection mainly includes a channel id allocated by the system to the electronic device and other devices in the connection, that is, signaling channel information. An electronic device may connect multiple devices at once, and then the signaling channel assigned to each device at a time may be different. This signaling channel is not a physical frequency band channel, but rather a logical channel. The end points of the channel are indicated by channel identifiers, channel ids, which are two bytes long, for example, the channel id of a signaling channel may be 0x 0001. Electronic devices can have a maximum of 65536 channels, i.e. an ACL link can have a maximum of 65536 channels. A data channel is established through the signaling channel and then data is transmitted by the data channel.
Specifically, the current signaling channel information is used to update the historical signaling channel information in the historical parameter information, that is, the current channel id information is used to update the channel id information in the historical parameter information, so that the current parameter information can be obtained.
And step 204, sending the parameter information to the other equipment.
In the embodiment of the present invention, after obtaining the current parameter information, the electronic device sends the current parameter information to other devices at one time, and if the data size is too large, the electronic device may also send the current parameter information to other devices in multiple times, so that the other devices extract the relevant information of the electronic device, for example, ACL parameter information of the electronic device, currently used channeld and relevant connection layer or application layer protocol information, rfcomm parameter information, and the like.
After step 204, step 205 or step 206 may be executed according to the feedback situation of the other device for the current parameter information.
In the embodiment of the present invention, if other devices support the device connection method in the embodiment of the present invention, after receiving the current parameter information sent by the electronic device, the other devices analyze the current parameter information and determine whether the information is incorrect. And if the judgment is accurate, establishing connection with the electronic equipment by using the parameter information, and returning confirmation information to the electronic equipment after the connection is successful.
In the embodiment of the present invention, if the other device does not support the device connection method in the embodiment of the present invention, the non-support information is returned to the electronic device; if other equipment supports the equipment connection method in the embodiment of the invention, but the parameter information is analyzed and then the information is wrong or missing, the error information is returned to the electronic equipment; if the communication channel between the other equipment and the electronic equipment fails, the electronic equipment cannot receive the reply information of the other equipment. If the above three situations occur, it indicates that the electronic device cannot establish a bluetooth connection with another device by the method in the embodiment of the present invention, and at this time, the electronic device and the other device may adopt the conventional method of step S1-step S3 in the prior art, that is, establish a bluetooth connection by exchanging information of both parties.
In summary, the device connection method provided in the embodiment of the present invention, besides the beneficial effects of the device connection method in fig. 1, also generates signaling channel information according to a channel identifier allocated by a system, and updates historical signaling channel information in the historical parameter information by using the signaling channel information to obtain the current parameter information, because the signaling channel information belongs to dynamic parameter information, after updating the historical parameter information by using the signaling channel information, the accurate current parameter information can be obtained, so that the electronic device and other devices successfully implement bluetooth connection; and when the confirmation information replied by the other equipment for the current parameter information is not received, or if the error information replied by the other equipment for the current parameter information is received, establishing Bluetooth connection by exchanging information of both sides, so as to provide another connection solution for the situation that the electronic equipment and the other equipment cannot realize Bluetooth connection by using the current parameter information, so that the electronic equipment and the other equipment can still successfully realize Bluetooth connection.
