Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of a bluetooth communication method according to the present invention, where the bluetooth communication method of the embodiment may be applied to a functional device provided with a bluetooth module, the functional device includes a bluetooth module and a functional module, and the functional device may be a bluetooth locator. As shown in fig. 1, in the present embodiment, the bluetooth communication method includes the steps of:
s1, registering at least one type of connection channel, wherein the type of the connection channel corresponds to the type of a terminal operating system.
It can be appreciated that the bluetooth module performs self-checking and initialization after the functional device is powered on. The method specifically comprises initializing a Bluetooth controller and a Bluetooth protocol, configuring parameters, performing memory self-checking and checking parameters or a plurality of the parameters so as to ensure the normal use of the functions of the Bluetooth module. When the Bluetooth protocol is initialized, a connection channel is registered so as to ensure that the Bluetooth module is connected with the terminal and communication is smoothly carried out.
Wherein at least one type of connection channel is registered, the type of connection channel corresponding to the type of terminal operating system. For example, if a connection channel is registered and bound with a service class UUID specified by the iAP2 protocol, the connection channel is corresponding to the iOS connection channel; and if one connecting channel is registered and bound with the UUID of the universal SPP service class, the connecting channel is correspondingly an Android connecting channel. It can be appreciated that the service class UUID includes a plurality of kinds, and when the service class UUID is specified by the iAP2 protocol, the service class UUID corresponds to the iOS operating system; when the service class UUID is the generic SPP, the service class UUID may correspond to other operating systems in addition to the Android operating system.
It is understood that the terminal includes, but is not limited to, mobile phones, notebook computers, tablet computers, palm computers, PAD and other electronic devices, and the operating system of the terminal may include, but is not limited to, an Android operating system, an iOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone operating system and the like; by registering the connection channel corresponding to the type of the terminal operation system, the subsequent connection and communication with the terminal of the corresponding type are facilitated.
The at least one type of connection channel comprises one type or a plurality of types of connection channels. When the connection channel of one type is included, the connection channel of the iOS corresponding to the iOS or the Android connection channel corresponding to the Android operating system is included; when multiple types of connection channels are included, the connection channels include iOS connection channels corresponding to iOS operating systems and/or Android connection channels corresponding to Android operating systems. It can be understood that users of terminals using the Android operating system and the iOS operating system currently occupy most of them, and the requirements of most of users can be met by registering the iOS connection channel and the Android connection channel.
Wherein one type of connection channel comprises one or more connection channels. When one type of connection channel comprises one connection channel, terminals of the same operating system in the field terminal are connected and communicated with the Bluetooth module through the corresponding type of connection channel in sequence. Namely, when one field terminal is connected with the Bluetooth module and data transmission is completed, the connection channel is released; and the other field terminal is connected with the Bluetooth module and completes data transmission.
When one type of connection channel comprises a plurality of connection channels, terminals of the same operating system in the field terminal are respectively connected and communicated with the Bluetooth module through an independent corresponding type of connection channel. Wherein, each connecting channel can correspond to different connecting channel numbers so as to distinguish each connecting channel.
It will be appreciated that, when the type of connection channel includes an iOS connection channel corresponding to the iOS operating system, in step S1, the bluetooth module performs self-checking and initializing, and further includes, communicating with the MFi coprocessor, detecting the MFi coprocessor and detecting version compatibility, so as to ensure normal registration of the iOS connection channel and subsequent normal communication with the terminal of the iOS operating system. Wherein the MFi coprocessor can be a CP3.0 coprocessor.

Specifically, when the operating system of the field terminal is an Android operating system, the Bluetooth module establishes SPP Bluetooth connection with the field terminal; when the operating system of the field terminal is an iOS operating system, the Bluetooth module establishes iAP2 Bluetooth connection with the field terminal. It will be appreciated that when the field terminal operating system is an iOS operating system, the bluetooth module communicates with the field terminal through the cryptographic authentication function of the MFi coprocessor and the iAP2 protocol.
S3, generating at least one format of function information to be transmitted, wherein the format of the function information to be transmitted corresponds to the type of the terminal operating system.
It will be appreciated that the functional device includes other modules in addition to the bluetooth module, for example, a functional module that generates at least one format of functional information to be transmitted. It will be appreciated that, in order to ensure the validity of the function information to be transmitted received by the field terminal, the format of the function information to be transmitted corresponds to the type of the terminal operating system. For example, when the original function data is packaged according to the format specified by the iAP2 protocol, the packaged data is the function information to be sent corresponding to the iOS operating system, and the format of the function information to be sent accords with the format requirement of the iOS operating system; and when the original function data is packaged according to the format specified by the SPP protocol, the packaged data is the function information to be transmitted corresponding to the Android operating system, and the format of the function information to be transmitted meets the format requirement of the Android operating system.
The bluetooth module and the field terminal in the step S2 can be connected by bluetooth, and then the function information to be sent is generated, namely, when the bluetooth module is in an idle state, the function information to be sent does not need to be generated, so that the working power consumption is reduced; or, the generation of the function information to be sent is completed before step S2, and it can be understood that, in the process from the start-up operation to the shutdown end operation of the function device, the generation of the function information to be sent can be completed once without generating again under the condition that the function information to be sent is unchanged or has no error. Therefore, after the Bluetooth module and the field terminal are connected by Bluetooth, the function information to be transmitted in a corresponding format can be transmitted to the field terminal with a corresponding operating system type, and the communication efficiency is improved.
It is understood that the at least one format of function information to be transmitted includes one or more formats of function information to be transmitted. When the function information to be sent in one format is included, the function information to be sent corresponding to the iOS operating system is included, or the function information to be sent corresponding to the Android operating system is included; when the function information to be sent in multiple formats is included, the function information to be sent corresponding to the iOS operating system and/or the function information to be sent corresponding to the Android operating system are included. It is to be understood that the format of the function information to be transmitted generated in step S3 corresponds to the type of the connection channel registered in step S1.
The function information to be sent may be information of various functions, specifically, information corresponding to functions of the function module. For example, when the function device is a bluetooth locator, the function device includes a bluetooth module and a locating module, and the locating module is the function module of the function device, at this time, the function information to be sent may include location information, that is, GPS locating data, and the location information is generated by the locating module. It can be understood that when the functional module is a positioning module, the original functional data is GPS positioning data, the positioning module packages the GPS positioning data according to a data format specified by a corresponding protocol, and the format of the packaged functional information to be sent is a format conforming to a corresponding operating system.
And S4, transmitting the function information to be transmitted in a corresponding format to the field terminal through a connection channel corresponding to the type of the field terminal operating system.
It can be understood that, after the bluetooth module establishes bluetooth connection with the field terminal and generates the function information to be transmitted, the function information to be transmitted in a corresponding format is transmitted to the corresponding field terminal through a connection channel corresponding to the type of the operating system of the field terminal.
When a plurality of field terminals of the same type of operating system are connected with the Bluetooth module through a plurality of connecting channels, the field terminals are sequentially connected with the Bluetooth module through an independent connecting channel respectively and keep connection, and after at least one format of function information to be transmitted is generated, the Bluetooth module transmits the function information to be transmitted in a corresponding format to the corresponding terminal through the corresponding connecting channel in a time sharing manner; that is, when a plurality of field terminals are on-line, the Bluetooth module transmits the function information to be transmitted to one field terminal, and then transmits the next field terminal, so that the networking transmission capacity is effectively improved.
And the field terminal presents the received function information to be sent to the user. For example, when the function information to be transmitted includes location information, the field terminal presents the received location information to the user, providing location services to the user.
In this embodiment, the bluetooth module may record and store the type of the existing part or all of terminal operating systems in advance, and the corresponding relation between the type of the terminal operating system and the format and the type of the connection channel of the function information to be sent, so as to select the function information to be sent in a corresponding format according to the type of the terminal operating system of the field terminal of the bluetooth connection, and send the function information to the corresponding terminal through the corresponding connection channel, thereby ensuring the validity of the function information to be sent received by the field terminal, and implementing the effective propagation of the function information to be sent.
Referring to fig. 2, fig. 2 is a flowchart of a second embodiment of the bluetooth communication method according to the present invention, wherein the bluetooth communication method according to the embodiment includes the following steps:
s1, registering at least one type of connection channel, wherein the type of the connection channel corresponds to the type of a terminal operating system.
S2, establishing Bluetooth connection with the field terminal according to the connection request sent by the field terminal.
S3, generating at least one format of function information to be transmitted, wherein the format of the function information to be transmitted corresponds to the type of the terminal operating system.
And S4, transmitting the function information to be transmitted in a corresponding format to the field terminal through a connection channel corresponding to the type of the field terminal operating system.
The present embodiment differs from the first embodiment in that in the present embodiment, in step S2, it includes:
s2-1, broadcasting connection information outwards for the field terminal to search for connection.
It can be understood that after the bluetooth module completes self-checking and initialization, connection information is broadcast outwards at any time for the field terminal to search for connection, wherein the connection information includes bluetooth names of the functional devices.
When the terminal of the user is located in the signal range of the connection information broadcast by the Bluetooth module and the user starts the Bluetooth function of the Bluetooth option of the terminal, the user can search the corresponding page of the terminal for the connection information corresponding to the current function equipment and select connection, so that a connection request is initiated to the Bluetooth module.
It will be appreciated that a terminal may include one or more bluetooth options, including a system bluetooth option located in a system setup page, or a bluetooth option located in an APP with bluetooth functions, that a user may turn on one or more bluetooth options' bluetooth functions simultaneously.
In step S1, when the same type of connection channel includes one and one terminal starts the bluetooth function of multiple bluetooth options, each bluetooth option of the terminal is connected to and communicates with the bluetooth module sequentially through the one connection channel. When the same type of connection channel comprises a plurality of connection channels and one terminal starts the Bluetooth functions of a plurality of Bluetooth options, the plurality of Bluetooth options are sequentially connected with the Bluetooth module through an independent connection channel, and the subsequent Bluetooth module respectively transmits the function information to be transmitted in a corresponding format to the terminal system or the APP where the Bluetooth options are located in a time-sharing mode through the corresponding connection channel.
It will be appreciated that in the embodiments of the present invention, a case where one terminal includes one bluetooth option is specifically described as an example, but the embodiments are equally applicable to a case where one terminal includes a plurality of bluetooth options.
S2-2, establishing bottom Bluetooth connection with the field terminal according to the connection information and the connection request sent by the field terminal through the corresponding connection channel.
It will be appreciated that the field terminal sends a connection request through a connection channel corresponding to its operating system type. And after receiving a connection request of the field terminal through the corresponding connection channel, the Bluetooth module establishes bottom Bluetooth connection with the field terminal.
S2-3, determining the type of the field terminal operating system according to the connection channel through which the connection request passes.
It will be appreciated that in step S1, the connection channels are registered, and unique connection channel numbers are assigned to each connection channel, and a correspondence between the connection channel numbers and the types of terminal operating systems is established.
When the Bluetooth module receives the connection request, the type of the operating system of the field terminal can be determined according to the connection channel number of the connection channel through which the connection request passes.
S2-4, handshake is carried out with the field terminal through a communication protocol corresponding to the type of the field terminal operating system, and the handshake is connected.
It may be appreciated that at least one type of communication protocol is stored in the bluetooth module, where the type of communication protocol corresponds to the type of terminal operating system, and includes, for example, the iAP2 protocol corresponding to the iOS operating system and the SPP protocol corresponding to the Android operating system.
And after the type of the operating system of the field terminal is determined, reading a communication protocol corresponding to the type of the operating system, carrying out handshake with the field terminal, and connecting the communication protocol with the field terminal, so as to establish Bluetooth connection between the Bluetooth module and the field terminal. After the connection is successful, the field terminal gives out corresponding prompt information to prompt the user.
When a plurality of field terminals exist, each field terminal repeats the Bluetooth connection steps, so that the plurality of field terminals are online simultaneously.
Further, in step S4, it includes:
s4-1, setting at least one type of control signal, wherein the type of the control signal corresponds to the format of the function information to be sent and the type of the connection channel.
It can be understood that in step S3, at least one format of function information to be transmitted is generated, and in step S4, by setting at least one type of control signal, a correspondence relationship between the type of the control signal and the format of the function information to be transmitted and the type of the connection channel is established. And judging the format of the function information to be sent according to the type of the control signal, and further selecting the type of a transmission channel for sending the function information to be sent.
The control signal may be generated by the function module and sent to the bluetooth module, and the corresponding relationship between the type of the control signal and the format of the function information to be sent, and the type of the connection channel may be stored in the bluetooth module, or may exist in the function module at the same time. It can be understood that the function module simultaneously sends the function information to be sent and the corresponding control signal to the bluetooth module, and the bluetooth module judges the format of the function information to be sent according to the control signal, so as to select a connection channel with the corresponding format for sending; or the Bluetooth module does not need to judge the format of the function information to be sent, and directly selects a corresponding connection channel to send according to the type of the control signal.
Wherein, the type distinction of the control signal can be realized by setting the level signal type of the control signal, for example, when the control signal is a high level signal, the format of the function information to be transmitted is an iOS format, and the function information should be transmitted through an iOS connection channel; when the control signal is a low-level signal, the format of the functional information to be sent is the Android format, and the functional information should be sent through an Android connection channel.
S4-2, determining the type of the connecting channel for sending the function information according to the type of the current control signal.
It can be understood that, when the bluetooth module receives the function information to be sent and the control signal sent by the function module, the type of the connection channel for sending the function information to be sent can be determined according to the control signal.
And S4-3, transmitting the function information to be transmitted to the field terminal through the corresponding type of connection channel.
And after determining the type of the connection channel, transmitting the function information to be transmitted to the field terminal through the connection channel of the type.
Because the iOS operating system has high requirements on the data format, in order to ensure the validity of the function information to be sent received by the terminal of the iOS operating system, further, after step S4-2, the method further includes:
S4-2-1, judging whether the format of the function information to be sent corresponds to an iOS operating system or not; if yes, executing the step S4-2-2; if not, step S4-3 is executed.
It can be understood that when the format of the function information to be sent corresponds to the iOS operating system, the format of the function information to be sent is judged, and when the format of the function information to be sent corresponds to other operating systems, for example, an Android operating system and the like, because the Android operating system has higher adaptability to the data format, the format judgment is not needed, the step S4-3 is directly executed, and the working power consumption is reduced.
S4-2-2, analyzing the function information to be sent, and obtaining format information of the function information to be sent.
It can be understood that the function information to be sent corresponding to the iOS operating system is parsed, and format information of the function information to be sent is obtained, so as to determine whether the format information meets the corresponding format requirement.
S4-2-3, judging whether the format information is consistent with the preset format information; if yes, executing the step S4-3; if not, step S4-2-4 is executed.
Understandably, in the bluetooth module, preset format information of function information to be sent corresponding to the iOS operating system is recorded and stored in advance; when the format information of the function information to be sent is consistent with the preset format information, judging that the current function information to be sent meets the format requirement, and executing the step S4-3; otherwise, if the current function information to be sent is judged to be not in accordance with the format requirement, executing the step S4-2-4.
S4-2-4, discarding the function information to be sent.
It can be appreciated that, when the functional device fails or other defects exist, the format of the to-be-sent functional information generated in step S3 may not match the format of the to-be-sent functional information expected to be generated, and in this embodiment, the to-be-sent functional information sent to the field terminal corresponding to the iOS operating system is made to conform to the format requirement by determining the format of the to-be-sent functional information corresponding to the iOS operating system, so that the integrity of the to-be-sent functional information is ensured.
It can be understood that the function of the bluetooth module is controlled by the bluetooth controllers, in this embodiment, the number of bluetooth controllers in the bluetooth module is fixed, for example, 1 bluetooth controller is included, and the above bluetooth communication method is programmed into the bluetooth controllers. The types of the registered connection channels and the number of the connection channels of various types are controlled by a program, namely, the types and the number of the connection channels can be increased or decreased in a program modifying mode, so that the system has expandability. Wherein, the Bluetooth module can be selected from FSC-BT836 Bluetooth module.
The bluetooth communication method of the embodiment is applicable to a bluetooth positioner, namely, the functional device can be the bluetooth positioner, the bluetooth positioner comprises a bluetooth module and a positioning module, namely, the positioning module is a functional module of the bluetooth positioner, and the bluetooth module is connected with the positioning module through a UART serial port.
