然而，参数协商和信息交互的流程涉及大量的蓝牙参数信息交互，且每次建立连接时均需要进行参数协商和信息交互，这一流程在蓝牙连接过程中会占用一定时间，从而造成设备蓝牙连接的时延较长。因此，如何缩短蓝牙连接时延是需要解决的技术问题。
发明内容

由于第二电子设备的版本与第一电子设备的版本相同，因此第二电子设备的蓝牙连接参数与第一电子设备的蓝牙连接参数相同，这样第一电子设备在获知两个设备版本相同的情况下，直接可以从本地调用这两个设备共有的蓝牙连接参数建立蓝牙连接。
通过上述方案，在两个电子设备需要建立蓝牙连接时，可以先判断两个电子设备的版本是否一致，进一步确定是否需要交互蓝牙连接参数：若版本一致，双方设备的蓝牙连接参数是一致的，则可以无需交互蓝牙连接参数，直接从本端设备处获取对方设备的蓝牙连接参数以建立蓝牙连接，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
在一种可能实施例中，在两个设备建立蓝牙连接之前，两个设备之间首先需要完成寻呼建立流程。
在第一方面的一种可能实现方式中，所述方法还包括：

通过上述方案，对于双方设备版本不同的情况，若双方设备之前配对连接过且存储对端设备的信息，则双方设备可以先判断对端设备信息相对于上一次连接时所采用的信息是否发生变更，如对端设备信息发生变更，则交互发生变更的信息以建立连接即可；若对端设备信息没有发生变更，则无需交互信息，直接调用存储的对端设备的信息以建立连接即可。
在一种可能实施例中，所述第一电子设备根据所述第一参数变更指示信息，确定与所述第二电子设备建立蓝牙连接所采用的信息，包括：
若所述第一参数变更指示信息指示有变更内容，则所述第一电子设备根据存储的所述第二电子设备的蓝牙连接参数和所述第一参数变更指示信息指示的变更内容，确定所述第二电子设备的第二蓝牙连接参数；

所述第一电子设备根据所述第一蓝牙连接参数和存储的所述第二电子设备的蓝牙连接参数，与所述第二电子设备建立蓝牙连接。
在双方设备版本不同情况下，若第一参数变更指示信息指示第一蓝牙连接参数无变更内容，则双方设备无需交互信息，直接调用存储的对端设备的信息以建立连接即可。如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
在第一方面的一种可能实现方式中，所述第二电子设备还用于，所述第一参数变更指示信息是采用掩码标记方式标记得到的信息。
通过上述方案，双方设备可以对本端设备发生变更的信息或节点进行标识，进而双方设备交互信息标识，这样在建立连接时双方设备可以根据信息标识，识别哪些信息发生变更，并针对变更信息重新协商交互，而无需针对未发生变更的信息进行交互及协商，如此可省略部分连接交互流程。因此，本申请可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。

第一方面介绍了两个设备在版本相同情况下以及在版本不同情况下分别采用不同方式建立蓝牙连接的过程，是基于不考虑建立连接过程中的动态因素而实现的，在实际实现时，在两个设备版本相同的情况下，双方设备在连接时可能还需要协商一些动态变化参数，例如连接建立请求、时钟、跳频参数等，对于这些动态变化的信息和操作，双方设备可以按照正常流程进行交互。
第二方面，本申请提供了另一种蓝牙连接方法，所述方法包括：
第一电子设备接收第二电子设备发送的第一参数变更指示信息，所述第一参数变更指示信息用于指示所述第二电子设备的第一蓝牙连接参数的变更内容；
若所述第一参数变更指示信息指示有变更内容，则所述第一电子设备根据存储的所述第一蓝牙连接参数和所述第一参数变更指示信息指示的变更内容，确定所述第二电子设备的第二蓝牙连接参数；
所述第一电子设备根据所述第二电子设备的第二蓝牙连接参数和所述第一电子设备的第三蓝牙连接参数，与所述第二电子设备建立蓝牙连接。

其中，上述第三蓝牙连接参数为第一电子设备本地存储的与第一电子设备对应的蓝牙连接参数，可以直接从第一电子设备本地直接调用。
可选的，若第二电子设备的蓝牙连接参数发生变更，则第一电子设备可以获取第二电子设备发生变更的蓝牙连接参数，并采用该蓝牙连接参数，将第一电子设备已存储的第二电子设备的蓝牙连接参数进行更新。
在第二方面的一种可能实现方式中，在所述第一电子设备接收第二电子设备发送的第一参数变更指示信息之前，所述方法还包括：
所述第一电子设备向所述第二电子设备发送第一请求消息，所述第一请求消息用于请求与所述第二电子设备建立蓝牙连接；
其中，所述第一电子设备接收第二电子设备发送的第一参数变更指示信息，包括：

需要说明的是，以上是以本端设备获取对端设备的变更信息为例说明的，在实际实现时，本端设备在信息发生变更的情况下，也可以将本端变更信息发送给对端设备，以指示对端设备将其存储的信息进行刷新。如此，双方设备可以在连接建立时针对信息变更部分进行交互，如此可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
在第二方面的一种可能实现方式中，所述方法还包括：在所述第一参数变更指示信息指示无变更内容的情况下，所述第一电子设备根据存储的所述第一蓝牙连接参数和所述第三蓝牙连接参数，与所述第二电子设备建立蓝牙连接。
通过上述方案，在两个电子设备需要建立蓝牙连接时，可以先判断对方设备的蓝牙连接参数是否有变化，进一步确定是否需要交互蓝牙连接参数或者需要交互哪些蓝牙连接参数：若对方设备的蓝牙连接参数未发生变化，则可以无需交互蓝牙连接参数，直接从本端设备处获取已存储的对方设备的蓝牙连接参数以建立蓝牙连接；若对方设备的蓝牙连接参数发生变化，则可以仅交互发生变化的信息以建立蓝牙连接，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
在第二方面的一种可能实现方式中，所述第一参数变更指示信息是采用掩码方式标记得到的信息。这样，双方设备可以对本端设备发生变更的信息或节点进行标识，进而双方设备交互信息标识，这样在建立连接时双方设备可以根据信息标识，识别哪些信息发生变更，并针对变更信息重新协商交互，而无需针对未发生变更的信息进行交互及协商，如此可省略部分连接交互流程。因此，本申请可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
需要说明的是，对于除TWS耳机这种对等设备之外的非对等设备间的连接(如耳机连接手机)，可以采用第二方面提供的方法省略部分连接交互流程。例如对于耳机和手机这样的蓝牙连接组合，由于配对前无法获知对端信息，因此无法按照TWS双耳这样从本地提取信息。需要在首次建立配对时，按照标准流程建立并协商交换后，即获取了对端静态配置和能力信息。本端设备将对端设备的信息记录下来，在下一次建立连接时，若对端设备的信息没有发生变更，则可以省去再一次的协商交换；或对端设备的信息有一部分发生变更，则仅交互发生变更的信息，从而获取到用于蓝牙连接的所有参数，即可建立蓝牙连接，如此可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。

图1示出了本申请的各个示例性实施例所涉及的通信系统的架构示意图。如图1所示，通信系统100可以包括多个支持无线通信技术的电子设备。例如，通信系统100可以包括蓝牙耳机11和手机12，其中蓝牙耳机11包括第一耳机01和第二耳机02，该蓝牙耳机11与手机12之间可以通过无线通信技术建立并保持无线连接；此外，第一耳机01与第二耳机02也可以作为支持无线通信技术的独立电子设备，彼此之间可以通过无线通信技术建立并保持无线连接。再例如，通信系统100还可以包括手机13，手机12和手机13之间可以通过无线通信技术建立并保持无线连接。
可选的，上述无线通信技术可以是蓝牙(bluetooth，BT)，例如传统蓝牙或者低功耗蓝牙(bluetooth low energy，BLE)，或者通用2.4G/5G频段无线通信技术等。
可选的，上述通信系统100可以包括如图1所示的蓝牙耳机和手机等，当然还可以包括平板电脑，无线音箱，无线手环，无线车载，无线智能眼镜，无线手表，增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备，媒体播放器(例如MP3、MP4等)、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、个人数字助理(personal digital assistant，PDA)、电视或智能手表等支持支持无线通信技术的电子设备，本申请实施例对通信系统100中的电子设备的设备类型不予具体限定。这些电子设备之间可以通过无线通信技术建立并保持无线连接(例如蓝牙连接)。需要说明的是，能够支持蓝牙功能的电子设备也被称为蓝牙设备。
示例性的，以电子设备为蓝牙耳机为例进行说明，蓝牙耳机可以有多种类型，例如可以是耳塞式、入耳式、头戴式、耳罩式或挂耳式蓝牙耳机等。蓝牙耳机可以包括分别佩戴于用户左耳和右耳的第一部分和第二部分，可以通过连接线相连，例如颈带式蓝牙耳机；也可以是相互独立的两部分，例如真无线立体声(true wireless stereo，TWS)耳机。
本申请中，蓝牙耳机为支持蓝牙通信协议的耳机。其中，蓝牙通信协议可以为传统蓝牙协议，还可以为BLE低功耗蓝牙协议；当然，还可以是未来推出的其他新的蓝牙协议类型。从蓝牙协议的版本角度而言，蓝牙通信协议的版本可以为下述中的任一版本：1.0系列版本、2.0系列版本、3.0系列版本、4.0系列版本、未来推出的其他系列版本。
示例性的，以蓝牙耳机为TWS耳机为例，如图1所示，TWS耳机11包括第一耳机01和第二耳机02，第一耳机01和第二耳机02内均设置有蓝牙模块，第一耳机01和第二耳机02可以通过蓝牙协议进行数据传输，其中这两个耳机的蓝牙通信协议版本可能相同，也可能不同。TWS耳机11从外观上看，第一耳机01和第二耳机02之间没有连接线，具有携带方便、易于使用的优点。可选的，第一耳机01和第二耳机02均可以包括麦克风，也就是说，第一耳机01和第二耳机02除了具有音频播放的功能外，还具有音频采集的功能。
在实际实现时，用户可以在双耳模式或单耳模式下使用TWS耳机11。在单耳模式下，用户佩戴第一耳机01，或者佩戴第二耳机02，进行听音乐或接/打电话等音频业务。在双耳模式下，用户可以左右耳分别佩戴这两个耳机进行听音乐或接/打电话等音频业务。在双耳模式下，这两个耳机有主耳机和副耳机之分。并且，在TWS耳机的使用过程中，两个耳机的主、副角色还可以基于不同的条件进行切换。例如，电量较高的耳机可以切换为 主耳机，电量较低的耳机可以切换为副耳机；再例如，假设用户佩戴第一耳机01和第二耳机02且第一耳机01为主耳机以及第二耳机02为副耳机，若用户摘掉第一耳机01，则此时第二耳机02可以从副耳机切换为主耳机，第一耳机01从主耳机切换为副耳机或者在预设时长后停止工作或直接停止工作。
一方面，在单耳模式下，若用户佩戴第一耳机01而未佩戴第二耳机02，此时第一耳机01为主耳机，则主耳机和手机可以通过信息交互及参数协商，进行配对并建立无线连接，以通过该无线连接实现主耳机和手机之间的无线通信和业务处理。示例性的，如图1所示，手机12与第一耳机01可以通过信息交互及参数协商，建立无线连接，若手机12发起音频业务，则手机12可以将音频信号发送给第一耳机01，第一耳机01接收到音频信号之后播放该音频信号。
另一方面，在双耳模式下，若用户佩戴第一耳机01和第二耳机02，此时第一耳机01和第二耳机02分别为主耳机和副耳机，则主耳机和副耳机可以通过信息交互及参数协商，进行配对并建立无线连接，以通过该无线连接实现主耳机和副耳机之间的无线通信和业务处理。
再一方面，在双耳模式下，若用户佩戴第一耳机01和第二耳机02，则主耳机和副耳机可以通过信息交互及参数协商，进行配对并建立无线连接，并且主耳机和手机也可以通过无线通信技术进行配对并建立无线连接。从而，实现手机与主耳机之间，主耳机与副耳机之间的无线连接、无线通信和业务处理。示例性的，如图1所示，手机12与第一耳机01可以通过信息交互及参数协商，建立无线连接；同样，第一耳机01与第二耳机02可以通过信息交互及参数协商，建立无线连接。例如，若手机12发起音频业务，则手机12可以将音频信号发送给第一耳机01，第一耳机01接收到音频信号之后将音频信号发送给第二耳机02，使得第一耳机01和第二耳机02分别播放该音频信号。
在一些实施例中，蓝牙耳机可以支持下述应用中的一种或多种：HSP(headset profile)应用、HFP(hands-free profile)应用、A2DP(advanced audio distribution profile)应用。其中，HSP应用代表耳机应用，提供手机与耳机之间通信所需的基本功能，蓝牙耳机可以作为手机的音频输入和输出接口。HFP应用代表免提应用，HFP应用在HSP应用的基础上增加了某些扩展功能，蓝牙耳机可以控制手机的通话过程，例如：接听、挂断、拒接、语音拨号等。A2DP应用为高级音频传送应用，支持传输立体声音频流。
在上述图1所示的通信系统100中，设备之间需要遵循蓝牙协议，实现蓝牙连接及信息交换。与开放系统互联参考模型(open system interconnection reference model，OSI)一样，蓝牙技术的协议体系也采用了分层结构，从底层到高层形成了蓝牙协议栈，各层协议定义了所完成的功能和使用数据分组格式，以保证蓝牙产品间的互操作性。其中，蓝牙的核心协议包括基带协议、链路管理协议LMP、逻辑链路控制和适配协议L2CAP和业务发现协议SDP等。为便于理解本申请实施例，图2示出了蓝牙协议架构的示意图。下面结合图2，对本申请实施例中涉及的这几个蓝牙协议进行解释说明，以便于本领域技术人员理解。
(1)基带协议(baseband)，为基带与链路控制层的协议，用于确保微微网内各蓝牙设备之间由射频构成的物理连接。蓝牙的射频系统是一个调频系统，其任一分组在指定时隙、指定频率上发送。它使用查询和分页进程同步不同设备间的发送频率和时钟，为基带 数据分组提供了两种物理连接方式，即面向连接(synchronous connection oriented link，SCO)和无连接(asynchronous connectionless，ACL)，而且在同一射频上可实现多路数据传送；SCO和扩展的SCO(extended SCO，eSCO)可以用于传输对时间要求很高的通信数据。ACL适用于数据分组，SCO适用于话音以及话音与数据的组合。对于不同数据类型(包括连接管理信息和控制信息)都分配一个特殊通道。可使用各种用户模式在蓝牙设备间传送话音，面向连接的话音分组只需经过基带传输，而不到达L2CAP。话音模式在蓝牙系统内相对简单，只需开通蓝牙话音连接就可以传送话音。
(2)链路管理协议(link manager protocol，LMP)，负责各蓝牙设备间连接的建立和设置。LMP通过连接的发起、交换和核实进行身份验证和加密，通过协商确定基带数据分组大小；还控制无线设备的节能模式和工作周期，以及微微网络内设备单元的连接状态。
(3)逻辑链路控制和适配协议(logical link control and adaptation protocol，L2CAP)，L2CAP是基带协议的上层协议，可以认为其与LMP并行工作，L2CAP和LMP的区别在于：当业务数据不经过LMP时，L2CAP为上层提供服务。L2CAP提供逻辑信道，称为L2CAP信道。L2CAP向上层协议提供面向连接的和无连接的数据服务，它采用了多路技术、分割和重组技术、群提取技术。L2CAP允许高层协议以64k字节长度收发数据分组。虽然基带协议提供了SCO和ACL两种连接类型，但L2CAP只支持ACL。
(4)业务发现协议(service discovery protocol，SDP)，发现业务在蓝牙技术框架中起着至关重要的作用，它是所有用户模式的基础。通过使用SDP，可以查询到设备的信息和服务类型，从而在蓝牙设备间建立相应的连接。
目前，不同电子设备之间的连接过程需要按照协议标准流程实现，该标准流程包括连接双方信息交互流程。具体的，在连接过程中，按照协议标准流程，电子设备之间需要进行一些参数协商和信息交互，比如LMP的特性支持、版本规格等交换，关键参数协商，SDP业务查询等。特别是SDP业务查询，需要先建立L2CAP信道，再进行查询，其过程是比较耗时的。因此，上述连接信息交互的流程在蓝牙连接过程中会占用一定时间，造成蓝牙连接时延较长。如何降低蓝牙连接时延以提升用户体验，是需要解决的技术问题。
鉴于上述情况，本申请基于上述系统架构提出一种蓝牙连接方法，可简化设备间的连接信息交互流程。该蓝牙连接方法应用于该蓝牙通信系统，该蓝牙通信系统包括第一电子设备和第二电子设备，本申请通过该蓝牙连接方法在第一电子设备与第二电子设备之间建立蓝牙连接。
由于蓝牙连接过程中需要获取和协商的对端设备信息，在设备生命周期内是固定的或者可修改的(半静态变化)，因此这些信息在没有发生变化的情况下可以作为已知信息看待，不需要在每次连接时重复进行协商和获取。特别是TWS耳机，其两个耳机的软硬件是一样的，所以两个耳机的大部分静态信息或半静态信息是一致的，因此本申请基于此提供了如下两种可能的实施方式来简化蓝牙连接过程中的信息交互环节。
在第一实施方式中，本申请实施例提供一种蓝牙连接方法，在两个电子设备需要建立蓝牙连接时，可以先判断两个电子设备的版本是否一致，进一步确定是否需要交互蓝牙连接参数：若版本一致，双方设备的蓝牙连接参数是一致的，则可以无需交互蓝牙连接参数，直接从本端设备处获取对方设备的蓝牙连接参数以建立蓝牙连接，如此可简化蓝牙连接过 程中的信息交互环节，提升蓝牙连接速度。
在第二实施方式中，本申请实施例提供另一种蓝牙连接方法，在两个电子设备需要建立蓝牙连接时，可以先判断对方设备的蓝牙连接参数是否有变化，进一步确定是否需要交互蓝牙连接参数或者需要交互哪些蓝牙连接参数：若对方设备的蓝牙连接参数未发生变化，则可以无需交互蓝牙连接参数，直接从本端设备处获取已存储的对方设备的蓝牙连接参数以建立蓝牙连接；若对方设备的蓝牙连接参数发生变化，则可以仅交互发生变化的信息以建立蓝牙连接，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
下面结合附图对本申请第一实施方式提供的蓝牙连接方法和第一实施方式提供的蓝牙连接方法分别进行示例性说明。
图3是根据本申请第一实施方式示出的一种蓝牙连接方法的流程图，参照图3所示，该方法300包括下述的步骤S301-S305。
S301，第一电子设备向第二电子设备发送第一版本信息，第二电子设备接收第一电子设备发送的第一版本信息。
在第一实施方式中，上述第一版本信息可以用于指示第一电子设备的版本。这里提到的电子设备的版本可以指电子设备支持或最近更新的蓝牙通信协议的版本，例如1.0系列版本、2.0系列版本、3.0系列版本、4.0系列版本，或者未来推出的其他系列版本。示例性的，第一电子设备的第一版本信息指示第一电子设备支持的蓝牙通信协议为4.0系列版本。当然，上述电子设备的版本还可以指电子设备的系统版本或者软件版本，具体可以根据实际使用需求确定，本申请实施例不作限定。
可选的，在第一实施方式中，在第一电子设备扫描到第二电子设备或发现第二电子设备的情况下，第一电子设备可以向第二电子设备发送第一版本信息，以发起蓝牙连接。其中，上述扫描或发现的过程可以是通过蓝牙通信技术实现的，该扫描或发现的过程即第一电子设备与第二电子设备建立寻呼的过程，也可以是通过其他无线通信技术(例如近场通信技术)实现的，具体可以根据实际使用需求确定，本申请实施例不作限定。为了便于说明，下文以双方设备寻呼完成后建立蓝牙连接为例进行示例性说明。
可选的，第一电子设备不但向第二电子设备发送第一版本信息，而且指示第二电子设备判断第一电子设备和第二电子设备的蓝牙通信协议版本是否一致。
需要说明的是，通常发起连接的电子设备可称为主设备，接受连接的设备可称为从设备。这里第一电子设备向第二电子设备发送第一版本信息，相当于发起连接，此时第一电子设备为主设备；第二电子设备接收第一版本信息，可作为从设备。
S302，第二电子设备判断第一版本信息与第二版本信息是否相同。
其中，该第二版本信息用于指示第二电子设备的版本。对于该第二版本信息的描述可以参见上述对第一版本信息的详细描述，此处不再赘述。
在实际实现中，以TWS耳机为例，第一耳机和第二耳机的蓝牙通信协议版本可能相同，例如两个耳机支持的蓝牙通信协议均为4.0系列版本；或者，第一耳机和第二耳机的蓝牙通信协议版本也可能不同，例如第一耳机支持的蓝牙通信协议为3.0系列版本，第二耳机支持的蓝牙通信协议为4.0系列版本。
在本申请实施例中，第二电子设备可以根据第一版本信息和第二版本信息，判断第二电子设备的版本与第一电子设备的版本是否相同，然后根据判断结果来确定后续执行步 骤：一方面，若第二电子设备判断第一版本信息与第二版本信息相同，即这两个蓝牙设备支持的蓝牙通信协议版本相同，则继续执行下述的步骤S303-S305；另一方面，若第二电子设备判断第一版本信息与第二版本信息不同，即这两个蓝牙设备支持的蓝牙通信协议版本不同，则继续执行下述的步骤S307或者S311。
S303，若版本相同，则第二电子设备向第一电子设备发送确认信息，第一电子设备接收第二电子设备发送的确认信息。
其中，确认信息用于指示第二电子设备的版本与第一电子设备的版本相同。若第一电子设备的版本和第二电子设备的版本相同，相同版本对应的蓝牙连接参数相同，则第一电子设备本地存储的蓝牙连接参数与第二电子设备本地存储的蓝牙连接参数相同，为例便于说明，下面在第一实施方式中将该相同版本对应的蓝牙连接参数称为第一蓝牙连接参数。
S304，第一电子设备从第一电子设备本地获取第一蓝牙连接参数，第二电子设备从第二电子设备本地获取第一蓝牙连接参数。
其中，该第一蓝牙连接参数为第一电子设备的版本对应的蓝牙连接参数。
S305，第一电子设备和第二电子设备根据第一蓝牙连接参数建立蓝牙连接。
在第一实施方式中，若版本一致，即双方设备的蓝牙连接参数是一致的，则可以无需交互蓝牙连接参数，例如无需交换LMP的特性支持和版本规格等，无需进行SDP业务查询等，而是可以直接从本端设备处获取对方设备的蓝牙连接参数，即可建立蓝牙连接，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
在一种可能实施例中，在两个设备发起蓝牙连接之前，两个设备之间首先需要完成寻呼建立流程。示例性的，参考图3，在步骤S301之前，方法300还可以包括步骤S306。
S306，第一电子设备和第二电子设备建立寻呼。
示例性的，假设第二电子设备处于可发现且可连接状态，可通过广播消息被发现，并且第一电子设备处于侦听状态，可通过扫描广播消息，发现其他电子设备。其中，第二电子设备广播的消息中可以携带第二电子设备的设备标识或蓝牙地址。若第一电子设备扫描到该广播消息，则第一电子设备可以根据广播消息中携带的设备标识或蓝牙地址，发现第二电子设备，进而向第二电子设备发送寻呼消息，若第一电子设备向第二电子设备返回寻呼响应，则第一电子设备和第二电子设备寻呼成功。
进一步的，在寻呼成功之后，第一电子设备可以向第二电子设备发送第一版本信息，即向第二电子设备发起连接，并且在判断第一电子设备和第二电子设备的版本相同的情况下，第一电子设备与第二电子设备直接调用双方设备共有的蓝牙连接参数，建立蓝牙连接。
通过本申请提供的一种蓝牙连接方法，在两个电子设备需要建立蓝牙连接时，可以先判断两个电子设备的版本是否一致，进一步确定是否需要交互蓝牙连接参数：若版本一致，双方设备的蓝牙连接参数是一致的，则可以无需交互蓝牙连接参数，直接从本端设备处获取对方设备的蓝牙连接参数以建立蓝牙连接，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
上面描述了双方设备版本相同情况下的蓝牙连接方法，而对于双方设备版本不同的情况，若双方设备之前配对连接过且存储对端设备的信息，则双方设备可以先判断对端设备信息相对于上一次连接时所采用的信息是否发生变更，如对端设备信息发生变更，则交互发生变更的信息以建立连接即可；若对端设备信息没有发生变更，则无需交互信息，直接 调用存储的对端设备的信息以建立连接即可。
示例性的，结合图3，如图4所示，本申请第一实施方式提供的蓝牙连接方法还可以包括下述的S307-S309，描述了双方设备版本不同情况下的蓝牙连接方法。需要说明的是，在第一实施方式中，假设第一电子设备和第二电子设备在本次建立连接之前已经配对连接过，并且双方设备已经在本端设备处存储对端设备的蓝牙连接参数或信息。例如，第一电子设备本地存储有第二电子设备的蓝牙连接参数。

其中，该第一参数变更指示信息用于指示第二电子设备的蓝牙连接参数的变更内容；
示例性的，第一参数变更指示信息指示第二电子设备的跳频参数发生变更，此时双方设备需要针对跳频参数进行信息协商，使得双方设备在跳频参数上保持一致，以使得更快地建立连接。
可选的，在第一实施方式中，在确认信息指示第二电子设备的版本与第一电子设备的版本不同的情况下，第一电子设备可以向第二电子设备发送第一请求消息，该第一请求消息用于请求与第二电子设备建立蓝牙连接。相应地，第二电子设备在接收到该第一请求消息后，可以根据第一请求消息，向第一电子设备发送第一响应消息，该第一响应消息包括第一参数变更指示信息。进一步的，第一电子设备在接收到该第一响应消息后，可以从第一响应消息中获取第一参数变更指示信息。
S308，若第一参数变更指示信息指示有变更内容，则第一电子设备根据存储的第二电子设备的蓝牙连接参数和第一参数变更指示信息指示的变更内容，确定第二电子设备的第二蓝牙连接参数。
示例性的，若对端设备的蓝牙连接参数发生变更，则本端设备可以获取对端设备发生变更的蓝牙连接参数，并采用该蓝牙连接参数，将本端设备已存储的对端设备的蓝牙连接参数进行更新。
需要说明的是，第二电子设备的蓝牙连接参数为第一电子设备本地存储的、与第二电子设备上次连接时采用的第二电子设备的蓝牙连接参数，是可以直接从第一电子设备本地直接获取到的。第一电子设备可以通过接收到的第一参数变更指示信息对第二电子设备的蓝牙连接参数进行信息刷新或替换，得到第二电子设备最新的蓝牙连接参数(即第二蓝牙连接参数)。
S309，第一电子设备根据第一蓝牙连接参数和第二蓝牙连接参数，与第二电子设备建立蓝牙连接。
其中，第二蓝牙连接参数为第一电子设备本地存储的第一电子设备最新的蓝牙连接参数，也是可以直接从第一电子设备本地直接调用的。
在第一实施方式中，本端设备获取对端设备发生变更的蓝牙连接参数，并采用该蓝牙连接参数，将本端设备已存储的对端设备的蓝牙连接参数进行更新。本端设备采用更新后的对方设备的蓝牙连接参数以及本端设备的蓝牙连接参数，即可建立蓝牙连接，而无需交互未发生变更的蓝牙连接参数，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
以上是针对第一参数变更指示信息指示第一蓝牙连接参数存在变更内容的情况说明 的，下面针对第一参数变更指示信息指示第一蓝牙连接参数无变更内容的情况进行说明。如图4所示，本申请实施例提供的蓝牙连接方法还包括下述的S310。
S310，若第一参数变更指示信息指示无变更内容，则第一电子设备根据第一蓝牙连接参数和存储的第二电子设备的蓝牙连接参数，与第二电子设备建立蓝牙连接。
在第一实施方式中，在双方设备版本不同情况下，若第一参数变更指示信息指示第一蓝牙连接参数无变更内容，则双方设备无需交互信息，例如无需交换LMP的特性支持和版本规格等，无需进行SDP业务查询等，而是可以直接调用存储的对端设备的信息以建立连接即可。如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
需要说明的是，本申请择一执行上述的S308-S309以及上述的S310，即本申请在第一参数变更指示信息指示有变更内容时执行S308和S309；在第一参数变更指示信息指示无变更内容时执行S310。
还需要说明的是，本申请择一执行上述的S303-S305以及上述的S307-S309(或者S307和S310)，即本申请在双方设备版本相同时执行S303-S305；在双方设备版本不同时执行S307-S309(或者S307和S310)。
可选的，在第一实施方式中，由于部分信息可能会在版本升级等情况下发生改变，因此本申请可以采用掩码记录的方式，每一个省略的流程点都映射到一个掩码比特。如果本端设备信息发生变更时，标记该掩码比特。当连接寻呼建立时，首先双方设备交换掩码标记，如果信息发生了变更，那么双方设备针对变更部分，在后续流程中发起相应的协商交互。
具体的，第二电子设备可以采用掩码标记方式标记第二电子设备的蓝牙连接参数的变更内容，得到第一参数变更指示信息。当然，第一电子设备也可以采用掩码标记方式标记第一电子设备的蓝牙连接参数的变更内容，得到第二参数变更指示信息。
示例性的，掩码比特可以包括0和1，对于未发生变更的信息部分可标记为0，对于发生变更的信息部分可标记为1；当然，也可以对于未发生变更的信息部分可标记为1，对于发生变更的信息部分可标记为0，具体可以根据实际使用需求确定，本申请实施例不作限定。
例如，以未发生变更的信息部分标记为0，发生变更的信息部分标记为1的标记规则为例，第一电子设备接收到第二电子设备发送的采用掩码比特标记的第一参数变更指示信息，可以根据上述标记规则，针对标记1的信息部分进行信息交互更新及协商。
通过上述方案，双方设备可以对本端设备发生变更的信息或节点进行标识，进而双方设备交互信息标识，这样在建立连接时双方设备可以根据信息标识，识别哪些信息发生变更，并针对变更信息重新协商交互，而无需针对未发生变更的信息进行交互及协商，如此可省略部分连接交互流程。因此，本申请可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
上面结合图4描述了双方设备版本不同情况下的一种蓝牙连接方法，即在双方设备版本不同情况下，交互参数变更指示信息，并根据参数变更指示信息确定需要交互的信息。下面结合图5，描述另一种蓝牙连接方法，即双方设备版本不同的情况下，可以按照标准的参数协商交互流程进行蓝牙连接。结合图3，如图5所示，本申请提供的蓝牙连接方法还可以包括下述的S311-S312。
S311，若版本不同，则第二电子设备向第一电子设备发送第一否定信息，第一电子设备接收第二电子设备发送的第一否定信息。
其中，第一否定信息用于指示第二电子设备的版本与第一电子设备的版本不同。
S312，第一电子设备与第二电子设备交互各自的蓝牙连接参数，建立蓝牙连接。
具体的，在两个设备支持的蓝牙通信协议版本不同的情况下，两个电子设备按照标准的参数协商交互流程，双方协商和交互信息，然后根据协商好的信息建立蓝牙连接。
示例性的，在第二电子设备的版本与第一电子设备的版本不同的情况下，第一电子设备向第二电子设备发送连接请求消息，该连接请求消息包括第一电子设备的蓝牙连接参数。第二电子设备接收第二电子设备发送的连接请求消息，并根据该连接请求消息，向第一电子设备发送响应消息，该响应消息包括第二电子设备的蓝牙连接参数。进一步的，第一电子设备接收第二电子设备发送的响应消息，然后第一电子设备和第二电子设备根据第一电子设备的蓝牙连接参数和第二电子设备的蓝牙连接参数，建立蓝牙连接。
需要说明的是，以上仅仅是示例性的描述，对于标准的参数协商交互流程的描述具体可以参见相关技术中对于标准的参数协商交互流程的相关描述，此处不予赘述。
需要说明的是，以上是以第一电子设备发送第一版本信息来发起连接的为例示例性的说明的，在实际实现时，本申请实施例不限于此，例如，第一电子设备还可以向其他电子设备发送连接请求消息来发起连接，并通过连接请求消息承载第一版本信息。
具体的，如图5所示，在第一电子设备与第二电子设备建立寻呼的情况下，第一电子设备可以向第二电子设备发送第一请求消息，该第一请求消息用于请求与第二电子设备建立蓝牙连接，并且该第一请求消息包括第一版本信息。相应地，第二电子设备在接收到该第一请求消息后，可以根据第一请求消息，将第一版本信息和第二版本信息进行比较，得到比较结果，然后向第一电子设备发送第一响应消息，该第一响应消息包括确认信息。进一步的，第一电子设备在接收到该第一响应消息后，可以根据第一响应消息，确定第一电子设备与第二电子设备版本是否相同。一方面。若版本相同，双方设备可以采用双方设备共有的相同版本对应的第一蓝牙连接参数建立蓝牙连接，而无需交互信息，如此可简化蓝牙连接流程。另一方面，若版本不同，则第二电子设备向第一电子设备发送第二响应消息，第一电子设备接收第二电子设备发送的第二响应消息，该第二响应消息包括第一否定信息。进一步的，第一电子设备与第二电子设备交互各自的蓝牙连接参数，建立蓝牙连接。即，第一电子设备在根据第二响应消息，确定其与第二电子设备版本不同时，按照传送的协议标准流程，即协商和交互信息，然后采用协商好的信息，与第二电子设备建立蓝牙连接。
综上所述，在第一实施方式中，若两个设备支持的蓝牙通信协议版本相同，则双方设备可以无需交互蓝牙连接参数，直接从本端设备处获取对方设备的蓝牙连接参数，即可建立蓝牙连接。若两个设备支持的蓝牙通信协议版本不同，则双方设备按照传统的协议标准流程交互信息后建立连接。
以上介绍了两个设备在版本相同情况下以及在版本不同情况下分别采用不同方式建立蓝牙连接的过程，是基于不考虑建立连接过程中的动态因素而实现的，也就是说上述第一蓝牙连接参数为静态参数。在实际实现时，在两个设备版本相同的情况下，双方设备在连接时可能还需要协商一些动态变化参数，例如连接建立请求、时钟、跳频参数等，对于 这些动态变化的信息和操作，双方设备可以按照正常流程进行交互。其中，上述第一请求消息和上述第一响应消息还可以用于承载需要协商的动态变化参数。假设第一电子设备与第二电子设备的版本相同，在第一电子设备与第二电子设备配对后，双方设备的一些信息和操作可能会发生动态变化。在此情况下，第一电子设备和第二电子设备可以交互动态变化参数，然后根据第一蓝牙连接参数和动态变化参数建立蓝牙连接。
示例性的，第一电子设备向第二电子设备发送第一电子设备的动态变化的第三蓝牙连接参数。然后，第二电子设备接收第三蓝牙连接参数，并根据第三蓝牙连接参数，向第一电子设备发送第二电子设备的动态变化的第四蓝牙连接参数。然后，第一电子设备可以根据第一蓝牙连接参数、第三蓝牙连接参数和第四蓝牙连接参数，与第二电子设备建立蓝牙连接。其中，第三蓝牙连接参数可以包括以下至少一项：连接请求、时钟、跳频参数等，类似地，第四蓝牙连接参数可以包括以下至少一项：连接响应、时钟、跳频参数等。如此，双方设备可以在获取对端设备的静态参数的情况下，协商并交互动态变化的参数，实现蓝牙连接。
本申请实施例中，对于蓝牙配对建立后没有变化的信息，通过本申请提供的蓝牙连接方法，可以省去在再次连接建立时进行协商和交互的环节。对于可能随着版本升级出现半静态变化的信息，可以通过标识变化信息以进行区分和识别，并在信息变化后再次建立连接时可以通过协商和交互进行信息刷新。
这样，版本相同的双方设备在建立蓝牙连接时，共有的蓝牙连接参数可以共享使用，无需交互传输给对方设备，仅需要交互协商一些动态变化参数，进而通过共有的蓝牙连接参数以及协商好的动态变化参数即可建立蓝牙连接，如此可简化蓝牙连接过程，提升蓝牙连接速度。
需要说明的是，本申请第一实施方式提供的蓝牙连接方法可以适用于设备型号相同的电子设备之间建立蓝牙连接的场景。示例性的，第一电子设备和第二电子设备分别为TWS耳机的第一耳机和第二耳机。可选的，第一耳机为主耳机，第二耳机为副耳机；或者，第一耳机为副耳机，第二耳机为主耳机，本申请实施例对此不作限定。
示例性的，针对TWS耳机的双耳互连这种场景，通常TWS的两个耳机是成套工作的，左右耳机是对等的设备，所以除了需要动态协商的参数外，对耳的信息完全可以通过本耳获取。此外，考虑到有一些信息会随软件版本升级变化，这些信息又非动态变化，因此可以与版本进行绑定，如果左右耳版本不一致，则需要走协商交互流程，可以待双耳版本升级一致后再裁剪交互。
当左右耳寻呼建立时，先检查双耳的版本一致性，一方面，如果双耳版本一致，则耳机通过从本耳机提取信息，替代通过流程交互从对耳获取。其中，对于动态变化的信息和操作，如连接建立请求、时钟、跳频参数等，则按照正常流程进行交互。另一方面，如果双耳版本不一致，则按照标准的蓝牙连接建立流程完成协商和交互。
综上所述，TWS耳机的两个耳机在进行配对连接时，只要两个耳机的版本一致，可以认为两个耳机版本和能力相关的信息都是一致的，对于对端耳机静态的信息直接可以从本端耳机处提取，替代相关技术中通过协商交互来获取蓝牙连接参数的方式，如此可简化蓝牙连接过程，提升蓝牙连接速度。与现有方案中在TWS双耳机首次配对以及后续连接时，每次都要完成标准的参数协商交互流程相比，在本申请实施例提供的蓝牙连接方法中， TWS双耳机在首次配对以及后续连接时可以省去部分协商交换流程，因此可以缩短连接建立时延。
当然，上述蓝牙连接方法还可以适用于设备型号不同的电子设备(例如电子设备和第二电子设备分别为手机和音箱)之间建立蓝牙连接的场景。
需要说明的是，本申请实施例提供的蓝牙连接方法不仅可以适用于设备间配对后的每次蓝牙连接的场景，而且也适用于设备间首次配对连接的场景。在两个电子设备首次配对连接时，可以先判断两个电子设备支持的蓝牙通信协议版本是否相同，若版本相同，则双方设备采用双方设备共有的蓝牙连接参数或信息进行配对并建立蓝牙连接；若版本不同，则按照标准的参数协商交互流程交互双方设备各自的蓝牙连接参数或信息以配对连接。
在相关技术的连接流程中，通常是按照协议标准流程，即双方需要协商和交互信息后根据协商好的信息建立连接，对于双方共有的已知信息，如果在每次连接时都重新走一遍协商和信息交互，那么会造成空口交互资源的浪费。与相关技术相比，本申请实施例提供的蓝牙连接方法是在建立连接时先判断两个设备版本是否一致，即若版本一致，两个设备的连接参数相同，则没有必要重新走一遍协商和信息交互，直接从本端设备处获取对方设备的蓝牙连接参数，即可建立蓝牙连接，如此可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
需要说明的是，本申请实施例包括但不限于上述由一方设备判断两个设备的版本是否相同，然后告知对方设备判断结果的实现方式，在实际实现时，本申请实施例还可以包括其他可能的实现方式，例如，双方设备可以交互各自的版本信息，再由双方设备判断两个设备的版本是否相同。示例性的，第一电子设备向第二电子设备发送第一版本信息，第二电子设备向第一电子设备发送第二版本信息，第一电子设备将本端设备的第一版本信息与对端设备的第二版本信息进行比较，以判断两个设备版本是否相同；第二电子设备将本端设备的第二版本信息与对端设备的第一版本信息进行比较，以判断两个设备版本是否相同。本申请根据设备版本信息判断设备版本是否相同的实现方式可以包括多种可能方式，具体根据实际使用需求确定，本申请实施例不作限定。
以上结合图3-图5对本申请实施例第一实施方式提供的蓝牙连接方法作了介绍，下面结合图6和图7对本申请实施例第二实施方式提供的蓝牙连接方法进行示例性说明。
首先需要说明的是，在第二实施方式中，假设第一电子设备和第二电子设备在本次建立连接之前已经配对过，并且双方设备在本端设备处已存储对端设备的蓝牙连接参数或信息，以便于后续双方设备再次连接时调用。下面结合图6示例性的说明电子设备之间配对过程。
如图6中的(a)所示，第一电子设备当前显示设置界面51，第一电子设备接收用户对设置界面51中的蓝牙选项52的选中操作，如图6中的(b)所示，第一电子设备响应于用户操作，显示蓝牙设置界面53，该蓝牙设置界面53中显示蓝牙处于开启状态，并且包括已配对的设备列表54以及可用设备列表55，例如已配对的设备列表54中包括手机1和手机2，例如可用设备列表55中包括FreeBuds 3、智能手表和蓝牙音箱。第一电子设备接收用户对可用设备列表55中FreeBuds 3项的选中操作，如图6中的(c)所示，第一电子设备响应于用户操作，在蓝牙设置界面53上显示蓝牙配对请求界面56，用于提示用户是否要与耳机FreeBuds 3配对。第一电子设备接收用户对蓝牙配对请求界面56中的配对 项57的选中操作，第一电子设备响应于用户操作，与耳机FreeBuds 3进行信息交互和协商，如图6中的(d)所示，第一电子设备隐藏蓝牙配对请求界面56，并且更新蓝牙设置界面53，其中已配对的设备列表54中增加FreeBuds 3项。如此，第一电子设备与耳机配对完成，此时第一电子设备存储耳机的蓝牙连接参数。
由于电子设备完成首次配对后，即获取了对端设备的蓝牙连接参数，例如属性信息和特性能力信息，一方面，如果这些信息在下次连接时未曾改变，则不需要在连接时再次交互获取，从而节省信息交互引入的连接时延。另一方面，如果由于版本升级或其他原因引起这些信息中部分信息发生改变，则双方设备可以按需在连接建立时针对信息变更部分进行交互并刷新。
图7是根据本申请第二实施方式示出的一种蓝牙连接方法的流程图，参照图7所示，该方法400包括下述的步骤S401-S405。
S401，第一电子设备和第二电子设备建立寻呼。
首先需要说明的是，在S401之前，第一电子设备和第二电子设备已经配对过，并且第一电子设备存储有第二电子设备的蓝牙连接参数(假设称为第一蓝牙连接参数)，第二电子设备存储有第一电子设备的蓝牙连接参数(假设称为第三蓝牙连接参数)。
S402，第二电子设备向第一电子设备发送第一参数变更指示信息，第一电子设备接收第二电子设备发送的第一参数变更指示信息。
其中，第一参数变更指示信息用于指示第二电子设备的第一蓝牙连接参数的变更内容。
示例性的，第一参数变更指示信息指示第二电子设备的跳频参数发生变更，此时双方设备需要针对跳频参数进行信息协商，使得双方设备在跳频参数上保持一致，以使得更快地建立连接。
可选的，在第二实施方式中，在第二电子设备扫描到第一电子设备或发现第一电子设备的情况下，第二电子设备可以向第一电子设备发送第一参数变更指示信息，以发起蓝牙连接。或者，在第一电子设备扫描到第二电子设备或发现第二电子设备的情况下，第一电子设备可以向第二电子设备发送连接请求消息，以发起连接，第二电子设备在接收到连接请求消息的情况下，向第一电子设备发送第一参数变更指示信息。示例性的，在第一电子设备与第二电子设备建立寻呼的情况下，第一电子设备可以向第二电子设备发送第一请求消息，该第一请求消息用于请求与第二电子设备建立蓝牙连接。相应地，第二电子设备在接收到该第一请求消息后，可以根据第一请求消息，向第一电子设备发送第一响应消息，该第一响应消息包括第一参数变更指示信息。进一步的，第一电子设备在接收到该第一响应消息后，可以从第一响应消息中获取第一参数变更指示信息。
需要说明的是，这里第一电子设备向第二电子设备发送第一请求消息，相当于发起连接，此时第一电子设备为主设备；第二电子设备接收第一请求消息并向第一电子设备反馈第一响应消息，相当于接受连接，此时第二电子设备可作为从设备。
在第二实施方式中，在两个设备发起蓝牙连接之前，两个设备之间首先需要完成寻呼建立流程。对于第一电子设备和第二电子设备建立寻呼的描述具体可以参见上述第一实施方式中对于设备间建立寻呼的详细描述，此处不再赘述。
S403，若第一参数变更指示信息指示有变更内容，第一电子设备根据存储的第一蓝牙 连接参数和第一参数变更指示信息指示的变更内容，确定第二电子设备的第二蓝牙连接参数。
示例性的，若对端设备的蓝牙连接参数发生变更，则本端设备可以获取对端设备发生变更的蓝牙连接参数，并采用该蓝牙连接参数，将本端设备已存储的对端设备的第一蓝牙连接参数进行更新。
需要说明的是，第一蓝牙连接参数为第一电子设备本地存储的与第二电子设备对应的蓝牙连接参数，是可以直接从第一电子设备本地直接获取到的。第一电子设备可以通过接收到的第一参数变更指示信息对第一蓝牙连接参数进行信息刷新或替换，得到第二电子设备最新的蓝牙连接参数(即第二蓝牙连接参数)。
S404，第一电子设备和第二电子设备根据第二蓝牙连接参数和第三蓝牙连接参数建立蓝牙连接。
其中，第三蓝牙连接参数为第一电子设备本地存储的与第一电子设备对应的蓝牙连接参数，也是可以直接从第一电子设备本地直接调用的。
在第二实施方式中，本端设备获取对端设备发生变更的蓝牙连接参数，并采用该蓝牙连接参数，将本端设备已存储的对端设备的蓝牙连接参数进行更新。本端设备采用更新后的对方设备的蓝牙连接参数以及本端设备的蓝牙连接参数，即可建立蓝牙连接，而无需交互未发生变更的蓝牙连接参数，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
S405，若第一参数变更指示信息指示无变更内容，则第一电子设备和第二电子设备根据存储的第一蓝牙连接参数和第三蓝牙连接参数建立蓝牙连接。
在第二实施方式中，若第一参数变更指示信息指示第二电子设备的蓝牙连接参数无变更内容，则无需交互对端设备的信息，直接调用存储的对端设备的信息以建立连接即可。如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
需要说明的是，本申请择一执行上述的S403-S404以及上述的S405，即本申请在第一参数变更指示信息指示有变更内容时执行S403-S404；在第一参数变更指示信息指示无变更内容时执行S405。
需要说明的是，以上是以本端设备获取对端设备的变更信息为例说明的，在实际实现时，本端设备在信息发生变更的情况下，也可以将本端变更信息发送给对端设备，以指示对端设备将其存储的信息进行刷新。如此，双方设备可以在连接建立时针对信息变更部分进行交互，如此可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
示例性的，第一电子设备可以向第二电子设备发送第二参数变更指示信息，第二电子设备接收第二电子设备发送的第二参数变更指示信息。其中，第二参数变更指示信息用于指示第一电子设备的蓝牙连接参数的变更内容。然后，第二电子设备可以根据第二参数变更指示信息指示的变更内容，确定第一电子设备的第三蓝牙连接参数。
例如，第二参数变更指示信息指示第一电子设备的时钟参数发生变更，此时双方设备需要针对时钟参数进行信息协商，使得双方设备在时钟参数上保持一致，以使得更快地建立连接。
可选的，第一电子设备可以在向第二电子设备发送第一请求消息时，通过第一请求消 息承载该第二参数变更指示信息。
类似于第一电子设备根据第一参数变更指示信息对本端存储的第二电子设备的蓝牙连接参数进行信息刷新或替换，第二电子设备可以根据第二参数变更指示信息，对本端存储的第一电子设备的蓝牙连接参数进行信息刷新或替换，得到第一电子设备最新的蓝牙连接参数。进一步的，在第二电子设备确定第一电子设备最新的蓝牙连接参数，以及第一电子设备确定第二电子设备最新的第二蓝牙连接参数之后，第二电子设备和第一电子设备可以根据第二电子设备最新的蓝牙连接参数和第一电子设备最新的蓝牙连接参数建立蓝牙连接。如此，双方设备可以在连接建立时针对信息变更部分进行交互，如此可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
通过本申请提供的蓝牙连接方法，在两个电子设备需要建立蓝牙连接时，可以先判断对方设备的蓝牙连接参数是否有变化，进一步确定是否需要交互蓝牙连接参数或者需要交互哪些蓝牙连接参数：若对方设备的蓝牙连接参数未发生变化，则可以无需交互蓝牙连接参数，直接从本端设备处获取已存储的对方设备的蓝牙连接参数以建立蓝牙连接；若对方设备的蓝牙连接参数发生变化，则可以仅交互发生变化的信息以建立蓝牙连接，如此可简化蓝牙连接过程中的信息交互环节，提升蓝牙连接速度。
需要说明的是，对于除TWS耳机这种对等设备之外的非对等设备间的连接(如耳机连接手机)，可以采用第二实施方式提供的方法省略部分连接交互流程。具体的，对于耳机和手机这样的蓝牙连接组合，由于配对前无法获知对端信息，因此无法按照TWS双耳这样从本地提取信息。但是，在首次建立配对时，按照标准流程建立并协商交换后，即获取了对端静态配置和能力信息。本端设备将对端设备的信息记录下来，在下一次建立连接时，就可以省去再一次的协商交换。
可选的，在本申请第二实施方式提供的蓝牙连接方法中，如果由于版本升级或其他原因引起这些信息中部分信息发生改变，则双方设备可以标记发生改变的这些信息，当双方设备交互标记后识别到对方设备有信息变化时，可以按需在连接建立时针对信息变更部分进行交互并刷新。例如，上述第一参数变更指示信息可以是采用掩码标记方式标记得到的信息。
在第二实施方式中，由于部分信息可能会在版本升级等情况下发生改变，因此本申请采用掩码记录的方式，每一个省略的流程点都映射到一个掩码比特。如果本端设备信息发生变更时，标记该掩码比特。当连接寻呼建立时，首先双方设备交换掩码标记，如果信息发生了变更，那么双方设备针对变更部分，在后续流程中发起相应的协商交互。
示例性的，掩码比特可以包括0和1，对于未发生变更的信息部分可标记为0，对于发生变更的信息部分可标记为1；当然，也可以对于未发生变更的信息部分可标记为1，对于发生变更的信息部分可标记为0，具体可以根据实际使用需求确定，本申请实施例不作限定。
例如，以未发生变更的信息部分标记为0，发生变更的信息部分标记为1的标记规则为例，第一电子设备接收到第二电子设备发送的采用掩码比特标记的第一参数变更指示信息，可以根据上述标记规则，针对标记1的信息部分进行信息交互更新及协商。
通过上述方案，双方设备可以对本端设备发生变更的信息或节点进行标识，进而双方设备交互信息标识，这样在建立连接时双方设备可以根据信息标识，识别哪些信息发生变 更，并针对变更信息重新协商交互，而无需针对未发生变更的信息进行交互及协商，如此可省略部分连接交互流程。因此，本申请可以简化连接建立流程，可提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
需要说明的是，与上述第一实施方式的TWS耳机双耳连接场景不同之处在于，第二实施方式需要通过首次配对获取对端设备信息后进行记录，并用掩码比特来指示信息的后续变更。考虑常规的蓝牙连接组合，通过本端设备存储对端设备信息的方式，可以在信息不发生变化或者发生部分变化的情况下裁剪一些不必要的协商交互，例如只要信息没有发生变化，就不会触发基于连接的信息协商和交换；再例如，若信息发生变化，则针对变更部分，发起相应的协商交互。因此，通过本申请方案的改进，可以在连接中裁剪交互流程，加快连接速度。
在相关技术的连接流程中，通常是按照协议标准流程，即双方需要协商和交互信息后根据协商好的信息建立连接，对于一些不变化的信息，如果在每次连接时都重新走一遍协商和信息交互，那么会造成空口交互资源的浪费。与相关技术相比，本申请方案可以针对未变更的信息，无需在连接时再次交互获取，以及对于由于版本升级或其他原因引起发生变更的信息，可以按需在连接建立时针对信息变更部分进行交互，从而可以缩短由于信息交互引入的连接时延。因此，本申请可以提升蓝牙连接速度，并且可以避免空口交互资源的浪费。
综上所述，本申请提供的蓝牙连接方法可以应用于下述场景1和场景2，通过该蓝牙连接方法可省去连接过程中信息交互和参数协商。
场景1、在首次配对连接后，对产品生命周期不会变更的信息，在连接双方中进行记录，在下次连接时不再进行交互。
场景2、对于可能半静态变更的信息，采用下述a)或b)所述方式省去连接过程中信息交互和参数协商。
a)与版本关联的信息，在连接寻呼成功后，先交换版本信息，如果版本未曾更新，则确认信息相对上次连接没有变化，后续流程不需要再进行协商和交换；
b)对信息项进行比特掩码标识，在连接寻呼成功后，先交换掩码比特，如果未曾变化则不需要在后续流程中进行协商和交换。如果信息发生变化，则针对变更部分，发起相应的协商和交互。
本文中描述的各个实施例可以为独立的方案，也可以根据内在逻辑进行组合，以实现不同的技术效果，这些方案都落入本申请的保护范围中。
本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构进行特别限定，只要能够通过运行记录有本申请实施例提供的方法的代码的程序，以根据本申请实施例提供的方法实现即可。例如，本申请实施例提供的方法的执行主体可以是第一电子设备，或者是第一电子设备中能够调用程序并执行程序的功能模块。为了实现上述本申请实施例提供的方法中的各功能，第一电子设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
