It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The first embodiment of the present invention provides a method for connecting a mobile terminal and a bluetooth device, wherein a flowchart of the method is shown in fig. 1, and specifically includes steps S101 to S103:
s101, a mobile terminal detects whether a plurality of trigger messages matched with Bluetooth equipment are received or not;
s102, under the condition that a plurality of trigger messages are received, the mobile terminal respectively acquires the equipment information of each Bluetooth equipment so as to realize successful pairing with each Bluetooth equipment;
and S103, under the condition of successful pairing with each Bluetooth device, the mobile terminal respectively establishes a corresponding RFECOMM channel with each Bluetooth device according to the acquired multiple device information.
Since the mobile terminal defaults to one connectable bluetooth device, the preset maximum connection number needs to be modified, so that the mobile terminal can be connected with a plurality of bluetooth devices simultaneously, that is, before the mobile terminal detects whether a plurality of trigger messages paired with the bluetooth devices are received, whether a modification request is received is detected, and under the condition that the modification request is received, the preset maximum connection number is modified according to the modification request. Wherein the modification request is used for modifying a preset maximum connection number of the accessible device in the predetermined protocol. Since the bluetooth device referred to in the present embodiment is a bluetooth headset, the predetermined protocols are HFP protocol and A2DP protocol.
When a user starts the Bluetooth function of the mobile terminal, the mobile terminal can automatically search all Bluetooth devices with the started Bluetooth function within the connectable range of the mobile terminal, the names of all the connectable Bluetooth devices are displayed on the screen of the mobile terminal, the user generates a trigger message for pairing with the Bluetooth devices by clicking the names of the Bluetooth devices, and when the user clicks a plurality of Bluetooth devices in sequence, the user generates a plurality of trigger messages.
Under the condition that a plurality of trigger messages are received, the mobile terminal respectively acquires the equipment information of each Bluetooth equipment to realize successful pairing with each Bluetooth equipment through the following steps:
s21, the mobile terminal sends a pairing request to a first Bluetooth device to be accessed;
s22, judging whether the number of successfully paired current connections is larger than a preset maximum connection number;
s23, under the condition that the number of successfully paired Bluetooth devices is smaller than or equal to the preset maximum connection number, the mobile terminal acquires the device information of the first Bluetooth device to be accessed so as to realize successful pairing with the first Bluetooth device to be accessed, and sends a pairing request to the second Bluetooth device to be accessed;
s24, adding 1 to the number of successfully paired, and repeatedly executing S22 and S23 until the number of successfully paired is larger than the preset maximum connection number.
After the mobile terminal is successfully paired with each Bluetooth device, the device information of the Bluetooth device is acquired to generate a pairing identification code, wherein the device information of the Bluetooth device comprises the name of the Bluetooth device and a unique MAC address corresponding to the Bluetooth device. The mobile terminal stores the name, the MAC address and the pairing identification code of the Bluetooth device in a stack mode. It should be appreciated that the earlier the information corresponding to the bluetooth device paired with the mobile terminal is stored in the stack.
After the mobile terminal establishes connection with a plurality of earphone devices, the mobile terminal can answer the call or play audio and video through the Bluetooth device. And under the condition that a request corresponding to a preset protocol is received, transmitting data corresponding to the preset protocol by using preset Bluetooth equipment, wherein the preset Bluetooth equipment is the Bluetooth equipment corresponding to the information stored last time in the information stored in a stack form. For example, the mobile terminal is sequentially connected with the bluetooth headset a, the bluetooth headset B and the bluetooth headset C, and then the information of the bluetooth headset in the stack is the bluetooth headset C, the bluetooth headset B and the bluetooth headset a from top to bottom, and in the case that the mobile terminal receives the request corresponding to the HFP protocol, the bluetooth device corresponding to the information stored in the stack form and stored in the last time in time is used, which is the bluetooth headset C in this embodiment.
The traditional single-to-single RFECOMM channel mode is changed into a single-to-multiple RFECOMM channel mode, so that the mobile terminal can be paired and connected with a plurality of Bluetooth devices at the same time, and the problem that the mobile terminal in the prior art can only be paired and connected with one device earphone and the user experience is poor is solved.
The second embodiment of the present invention provides an apparatus for connecting a mobile terminal and a bluetooth device, the structure of which is shown in fig. 2, and the apparatus for connecting a mobile terminal and a bluetooth device includes a detection module 201, a pairing module 202, and a connection module 203 that are sequentially coupled.

Since the mobile terminal defaults to one connectable bluetooth device, the preset maximum connection number needs to be modified, so that the mobile terminal can be connected to a plurality of bluetooth devices simultaneously, that is, before the mobile terminal detects whether a plurality of trigger messages paired with the bluetooth devices are received, whether a modification request is received is detected by the detection module 201, and in the case that the modification request is received, the modification module modifies the preset maximum connection number according to the modification request. Wherein the modification request is used for modifying a preset maximum connection number of the accessible device in the predetermined protocol. Since the bluetooth device referred to in the present embodiment is a bluetooth headset, the predetermined protocols are HFP protocol and A2DP protocol.
When a user starts the Bluetooth function of the mobile terminal, the mobile terminal can automatically search all Bluetooth devices with the started Bluetooth function within the connectable range of the mobile terminal, the names of all the connectable Bluetooth devices are displayed on the screen of the mobile terminal, the user generates a trigger message for pairing with the Bluetooth devices by clicking the names of the Bluetooth devices, and when the user clicks a plurality of Bluetooth devices in sequence, the user generates a plurality of trigger messages.
Preferably, the pairing module 202 specifically performs the following steps when pairing between the mobile terminal and the bluetooth device:
s31, sending a pairing request to a first Bluetooth device to be accessed;
s32, judging whether the number of successfully paired current connections is larger than a preset maximum connection number;
s33, acquiring equipment information of the first Bluetooth equipment to be accessed under the condition that the number of successfully paired equipment is smaller than or equal to the preset maximum connection number, so as to realize successful pairing with the first Bluetooth equipment to be accessed, and sending a pairing request to the second Bluetooth equipment to be accessed;
s34, adding 1 to the number of successfully paired, and repeatedly executing S32 and S33 until the number of successfully paired is larger than the preset maximum connection number.
After pairing with each bluetooth device is successful, the pairing module 202 obtains device information of the bluetooth device to generate a pairing identification code, where the device information of the bluetooth device includes a name of the bluetooth device and a unique MAC address corresponding to the bluetooth device. The device for connecting the mobile terminal and the Bluetooth device further comprises a storage module, which is coupled with at least the pairing module and is used for storing the name, the MAC address and the pairing identification code of the Bluetooth device in a stack mode. It should be appreciated that the earlier the information corresponding to the bluetooth device paired with the mobile terminal is stored in the stack.
The device for connecting the mobile terminal and the Bluetooth equipment changes the traditional single-to-single RFECOMM channel mode into a single-to-multiple RFECOMM channel mode, so that the mobile terminal can be paired and connected with a plurality of Bluetooth equipment at the same time, and the problem that the mobile terminal in the prior art can only be paired and connected with one equipment earphone and the user experience is poor is solved.
A third embodiment of the present invention provides a mobile terminal, whose structure schematic diagram is shown in fig. 3. As shown in fig. 3, the mobile terminal includes the following modules coupled to each other: bluetooth module 301 and setup module 302. The bluetooth module 301 mainly includes an authentication unit 3011 (corresponding to a modification module in the second embodiment of the present invention), a pairing unit 3012 (corresponding to a pairing module in the second embodiment of the present invention), a connection unit 3013 (corresponding to a connection module in the second embodiment of the present invention), a call unit 3014, and an audio/video playing unit 3015; the setting module 302 presents the user with setting options for setting the bluetooth name of the mobile terminal, whether it is visible, and the maximum number of connections, mainly in the form of a bluetooth menu.
Further, after clicking the bluetooth menu in the setting module 302, the user opens the setting option, has a maximum connection number option, and after selecting, the user can input the maximum connection number that the mobile terminal needs to access. The default maximum connection number of the software bottom layer of the mobile terminal is 1, when the user inputs the maximum connection number N to be accessed, the value is sent to the software bottom layer through the authentication unit 3011, and the maximum connection number of the HFP protocol and the A2DP protocol supported by the mobile terminal is modified to the maximum connection number N required by the user by the software bottom layer, at this time, the maximum connection number displayed in the setting module 302 is N set by the user.
In this embodiment, after the bottom layer modifies the maximum connection number of the HFP protocol and the A2DP protocol, when the user searches for available bluetooth devices nearby, the pairing unit 3012 may pair with multiple bluetooth headset devices at the same time, and may access a second headset to be accessed at the same time in the process of clicking the first headset to be accessed. When the mobile terminal is paired with the first bluetooth headset, the basic information (name and MAC address) of the bluetooth headset is saved and a unique pairing identification code is generated, and the basic information of the bluetooth headset can be read by using the API of bluetooth. In the process of acquiring the basic information of the first Bluetooth headset device, the mobile terminal can be paired with the second Bluetooth headset to acquire and store the basic information of the second Bluetooth headset. The name and the MAC address of each successfully paired bluetooth headset are stored in a stack, and the pairing identification codes of the mobile terminal and each bluetooth headset are stored in the stack at the same time, as shown in fig. 4, the earlier the information corresponding to the bluetooth device paired with the mobile terminal is stored in the stack. The mobile terminal can be paired with a plurality of Bluetooth devices simultaneously, the pairing process is changed from a traditional serial mode into a parallel mode, the pairing connection efficiency is improved, and the pairing connection process of the terminal and the plurality of Bluetooth devices is quickened. In order to increase user experience, when the number of paired devices exceeds the preset maximum connection number in the authentication unit, a prompt of a user popup prompt that the number of devices to be paired is full and a new device cannot be accessed is given.
After pairing is successful, the mobile terminal can be paired with a plurality of Bluetooth headsets, firstly, a Bluetooth device set which is already paired with the current terminal device is queried through scanning, secondly, whether the device to be accessed has a Bluetooth connection service started or not is judged, finally, a connection unit 3013 initiates a connection request, connection is initiated in a stack from bottom to top according to the information of the paired Bluetooth headsets, the connection request is initiated in parallel, the connection request is initiated to each device according to the device MAC address information stored in the stack, and the mobile terminal and each headset have a Bluetooth socket on the same RFECOMM after the connection is established successfully, so that a plurality of RFECOMM channels are established when the mobile terminal is paired with the plurality of headsets, namely, a traditional single-to-single RFECOMM channel mode is changed into a single-to-multiple RFECOMM channel mode. When the number of connected devices exceeds the maximum number of connections preset in the authentication module, a prompt that the user pops up a prompt that the device to be accessed is full and a new device cannot be accessed is given.
When the mobile terminal calls in or out, if the mobile terminal and the bluetooth headset have already established a pairing connection, the call unit 3014 sends an instruction to judge the supporting condition of the HFP protocol and the A2DP protocol of the currently connected bluetooth headset, that is, when the bluetooth headset supports the HFP protocol, call sound can be correctly transmitted from the bluetooth headset supporting the HFP protocol, and when the bluetooth headset does not support the HFP protocol, call sound cannot be transmitted from the bluetooth headset not supporting the HFP protocol. When the mobile terminal is powered off to other mobile terminals, according to the stack storage sequence when the Bluetooth headset is connected with the mobile terminal in a pairing mode, if the Bluetooth headset which is connected with the mobile terminal last successfully supports the HFP protocol, the Bluetooth headset which is connected with the mobile terminal last successfully is activated, and after the other party is connected with the telephone, only the Bluetooth headset which is connected with the mobile terminal last successfully can communicate with the other party. In the conversation process, if the last connected Bluetooth earphone is closed, the conversation can be automatically switched to the last connected Bluetooth earphone for conversation according to the stack storage sequence, and the conversation can be normally carried out as long as the connected HFP earphone is not closed. However, when the last bluetooth headset successfully connected with the mobile terminal does not support the HFP protocol, the last bluetooth headset successfully connected with the mobile terminal is activated according to the stack storage sequence, and when the other party is connected with the phone, only the last bluetooth headset successfully connected with the mobile terminal can communicate with the other party. Under the condition that the mobile terminal calls, a plurality of Bluetooth headsets which are connected by the mobile terminal and support the HFP protocol have incoming call ringtones, at the moment, a user can select any headset which supports the HFP protocol to answer, and after answering, the headset can call.
When audio and video playing is performed on the mobile terminal, the audio and video playing unit 3015 can judge whether the currently connected Bluetooth headset supports the A2DP protocol, if so, audio and video playing sound can be correctly played from all Bluetooth handsets supporting the A2DP protocol, namely, a plurality of users are simultaneously supported to listen to the content played by the mobile phone; when the mobile terminal is connected with one Bluetooth earphone in a pairing mode to play audio and video, after the mobile terminal is connected with a second Bluetooth earphone in a pairing mode, the two earphone can play audio and video simultaneously if both support an A2DP protocol and play the same content, and when one Bluetooth earphone is disconnected, the disconnected Bluetooth earphone does not continue to play audio and video, but the audio and video of the other Bluetooth earphone is not delayed. When the mobile terminal is paired with the Bluetooth headset to play the audio and video, all the Bluetooth headsets supporting the A2DP protocol are closed, the audio and video can be paused to play, when at least two Bluetooth headsets supporting the A2DP protocol are actively reconnected successfully, the connected Bluetooth headsets are clicked to play the audio and video, and the connected Bluetooth headsets resume to listen to the audio and video.
If an incoming call exists in the audio/video playing process, at this time, the communication unit 3014 detects which Bluetooth earphones stored in the earphone stack support the HFP protocol, and all Bluetooth earphones supporting the HFP protocol have ringing sounds, at this time, a user can select any earphone to communicate; if a certain Bluetooth earphone supports the HFP protocol and supports the A2DP protocol, but because the priority of the HFP protocol is higher than that of the A2DP protocol, the Bluetooth earphone generates ringing sound and the audio and video pauses to play when the mobile terminal has an incoming call, and if a user selects to use other Bluetooth earphone to answer the call, the audio and video can continue to play after the call is answered. If the Bluetooth headset is ready to be powered off in the process of playing the audio and video, at the moment, the communication unit 3014 detects whether the Bluetooth headset which is finally connected with the mobile terminal in a pairing way in the headset stack storage supports the HFP protocol, and if the Bluetooth headset supports the HFP protocol, the headset has ringing sound; if the Bluetooth headset is not supported, the Bluetooth headset is judged from top to bottom in a stack by analogy until the Bluetooth headset supporting the HFP protocol is detected, and if a certain Bluetooth headset supports the HFP protocol and supports the A2DP protocol at the same time, the Bluetooth headset can generate ringing sound and pause audio and video playing because the priority of the HFP protocol is higher than that of the A2DP protocol, and the audio and video playing can be continued when the call is ended.
In order to facilitate the use of the user and view the connection state of the current mobile terminal, in this embodiment, a widget menu is provided in the mobile terminal, where the widget menu is disposed on the home screen of the mobile terminal and is used to display the connection state of the mobile terminal and the bluetooth headset, so that the user can conveniently view the information such as the number of connected headsets and the current electric quantity of the headset. When the user clicks the widget menu on the screen, the user can quickly enter the bluetooth menu of the setting module 302, that is, the widget menu and the setting module 302 always keep an interactive state.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, and accordingly the scope of the invention is not limited to the embodiments described above.
