在该方案中，对于配对使用的第一无线耳塞和第二无线耳塞，电子设备可以先与第一无线耳塞建立蓝牙连接，借助第一无线耳塞的媒介作用，实现双通路连接(或称双发连接)。
在一种可能的实现方式中，该方法还包括：电子设备通过第一蓝牙连接，向第一无线耳塞发送音频数据；电子设备通过第二蓝牙连接，向第二无线耳塞发送音频数据。
也就是说，在实现双发连接后，电子设备可以分别通过与第一无线耳塞和第二无线耳塞各自之间的蓝牙连接通路，交互音频信号。
在另一种可能的实现方式中，在电子设备建立与第二无线耳塞之间的第二蓝牙连接之前，该方法还包括：电子设备接收第一无线耳塞发送的指示第二无线耳塞与第一无线耳塞配对使用的信息。

这样，在第一无线耳塞和电子设备互相获知对方支持双发后，可以执行双发连接流程。
在另一种可能的实现方式中，电子设备向第一无线耳塞发送第二识别信息，包括：电子设备显示第一无线耳塞的标识；电子设备在检测到用户针对标识的操作后，向第一无线耳塞发送第二识别信息。

本申请以下实施例将以手机为电子设备01，TWS耳机为外接设备02，手机01和TWS耳机02之间以蓝牙方式建立连接为例，对本申请实施例提供的配对连接方法进行阐述。
TWS耳机可以通过与手机之间的蓝牙连接交互音频(audio)数据，该音频数据可以包括媒体(media)数据和语音(voice)数据等。例如，TWS耳机可以为用户播放音乐、录音、视频文件中的声音等媒体数据；在电话、音频通话、视频通话场景下，可以播放来电提示音、播放通话对端的语音数据，并采集用户的语音数据发送给手机；在游戏场景下，可以播放背景音乐、游戏提示音、队友的语音数据等，并采集用户的语音数据发送给手机；在微信语音消息场景下，可以播放语音消息，采集用户录制的语音数据并发送给手机；在语音助手等场景下，可以采集用户的语音数据发送给手机。
目前，TWS耳机与手机之间的蓝牙连接方案主要有监听方案、转发方案以及近场磁感应(near field magnetic induction，NFMI)方案等。
参见图4A，在监听方案中，TWS耳机400可以包括主耳塞401和副耳塞402，手机403和主耳塞401建立蓝牙连接，完成音频数据到主耳塞401的交互，并完成手机403和TWS耳机400触发的业务动作(比如，播放、暂停、切换到上一首、切换到下一首等)；双耳塞之间建立有蓝牙连接，完成双耳塞之间的信息同步；副耳塞402通过监听主耳塞401和手机403之间的蓝牙链路获取音频数据。
参见图4B，在转发方案中，TWS耳机400可以包括主耳塞401和副耳塞402，手机403和主耳塞401之间建立蓝牙连接，完成音频数据到主耳塞401的交互，并完成手机403和TWS耳机400触发的业务动作；双耳塞之间建立有蓝牙连接，完成双耳塞之间的信息同步；主耳塞401通过与副耳塞402之间的蓝牙链路向副耳塞402转发音频数据。
参见图4C，在NFMI方案中，TWS耳机400可以包括主耳塞401和副耳塞402，手机403和主耳塞401之间建立蓝牙连接，完成音频数据到主耳塞401的交互，并完成手机403和TWS耳机400触发的业务动作；双耳塞之间建立有NFMI连接，完成双耳塞之间的信息同步；主耳塞401通过与副耳塞402之间的NFMI链路向副耳塞402转发音频数据。
上述监听方案、转发方案和NFMI方案只建立手机与一只TWS耳塞之间的配对连接，手机仅通过与该只耳塞之间的连接与TWS耳机交互音频数据，因而这些连接方案也可以称为单发方案。
在本申请实施例提供的配对连接方法中，参见图4D，手机可以与配对使用TWS耳塞中的每只TWS耳塞之间都建立蓝牙连接，并同时保持两路蓝牙连接，从而与每只TWS耳塞分别交互音频数据、业务控制数据和同步数据等，实现音频数据播放和业务动作控制等操作，因而可以称为双连接方案或双发方案。在建立手机与TWS耳机之间的双发连接后，两只TWS耳塞之间可以保持无线连接，也可以断开无线连接。两只TWS耳塞可以收到相同的音频数据，根据自己属于左耳塞或者右耳塞来播放音频数据中的左声道音频数据或右声道音频数据。或者手机可以分别给左耳塞发送左声道音频数据，给右耳塞发送右声道音频数据，从而使得两个耳塞播放不同声道的音频数据。
例如，在一实施例中，TWS耳机包括第一耳塞和第二耳塞。在使用TWS耳机时，手机可以先建立与第一耳塞的蓝牙配对连接，而后再建立手机与第二耳塞的蓝牙配对连接，从而建立手机与每只TWS耳塞之间的蓝牙连接，实现双发连接。
在建立双发连接后，两只TWS耳塞相互配合、协同工作，分别实现对同一音频数 据的左声道信号和右声道信号的同步播放。在建立双发连接后，手机与每只TWS耳塞之间的链路可以分别占用2.4GHZ频段，两只耳塞不需要分享2.4GHZ频段，因而TWS耳机的传输带宽较大。并且，每只耳塞均可以通过各自与手机之间的链路及时回复重发、确认等消息，因而能够尽快响应，丢包率小，抗干扰性强，音频数据的音质较好。而且，手机与一只TWS耳塞之间的链路问题(例如信道质量差、断链等)不会影响到另一只TWS耳塞，手机与另一只TWS耳塞之间仍可正常传输数据，不会造成数据传输的中断。此外，在双发方案中，TWS耳机的两个耳塞可以直接接收手机发送的数据，而不需要向其他方案那样进行转发。
并且，TWS的第一耳塞和第二耳塞之间也可以建立无线连接，从而在手机建立与第一耳塞的蓝牙配对连接后，手机和第二耳塞之间可以通过第一耳塞作为媒介设备来交互手机或第二耳塞的蓝牙地址等信息，而后可以根据交互获得的蓝牙地址，建立手机与第二耳塞之间的蓝牙配对连接，实现双发连接。其中，蓝牙地址用于唯一标识一个蓝牙设备，例如蓝牙地址可以是MAC地址或序列号等。本申请以下实施例中以蓝牙地址为MAC地址为例进行说明。
其中，双发连接的具体实现方式可以有多种。
例如，在一种情况下，在用户使用TWS耳机时，两只TWS耳塞之间可以先进行配对连接；之后，手机再与TWS耳机中的第一耳塞建立配对连接；后续，手机和第二耳塞之间可以通过第一耳塞交互手机或第二耳塞的MAC地址，而后手机和第二耳塞可以根据交互获得的MAC地址，建立手机与第二耳塞之间的配对连接。
在另一种情况下，在用户使用TWS耳机时，手机可以先与TWS耳机中的第一耳塞建立配对连接；而后，两只TWS耳塞之间进行配对连接；后续，手机和第二耳塞之间可以通过第一耳塞交互手机或第二耳塞的MAC地址，而后手机或第二耳塞根据交互获得的MAC地址，建立手机与第二耳塞之间的配对连接。
在又一种情况下，手机与TWS耳机中的第一耳塞建立配对连接，并交互音频数据，第一耳塞为单耳模式。在第一耳塞切换为双耳模式后，第一耳塞与第二耳塞之间进行配对连接；而后，手机和第二耳塞之间可以通过第一耳塞交互手机或第二耳塞的MAC地址，后续，手机和第二耳塞可以根据交互获得的MAC地址建立手机与第二耳塞之间的配对连接。或者，在第一耳塞切换为双耳模式后，第一耳塞与手机断开蓝牙连接，而后重新建立手机与TWS耳机之间的双发连接。
本申请以下实施例将以音乐播放场景下，通过建立手机与TWS耳机之间的双发连接，来为用户播放音乐为例进行说明。参见图5，双发连接方法可以包括：
500、手机开启蓝牙功能。
在用户希望使用TWS耳机播放音乐时，示例性的，参见图6，用户可以打开手机上的蓝牙功能。
501、TWS耳机中的第一耳塞和第二耳塞之间建立无线配对连接。
例如，在一种情况下，第一耳塞和第二耳塞置于耳机盒中，在耳机盒开盒时，或者某一只耳塞从耳机盒中取出后，或者用户触摸(例如，轻触、点击或长按等)耳机盒上的第一控件后，第一耳塞和第二耳塞之间可以通过BLE方式或BR/EDR方式进行蓝牙配对连接。当采用BLE方式时，两只耳塞之间可以通过BLE广播互相发现，并 通过BLE可连接广播消息建立蓝牙配对连接。当采用BR/EDR方式时，两只耳塞之间可以通过寻呼扫描(page scan)或查询扫描(inquiry scan)进行发现，并通过寻呼(page)和寻呼响应(page response)等消息建立蓝牙配对连接。采用这两种方式进行蓝牙配对连接的具体过程可以参考现有技术，此处不予赘述。
在另一种情况下，若第一耳塞和第二耳塞出厂时已经预先配对，或本次使用前已进行了配对，则第一耳塞和第二耳塞之间相互保存有对方的MAC地址。在放置第一耳塞和第二耳塞的耳机盒开盒时，或者用户触摸耳机盒上的第一控件后，或者某一只耳塞从耳机盒中取出后，第一耳塞和第二耳塞可以根据保存的对方的MAC地址进行寻呼，从而建立蓝牙连接。
其中，若第一耳塞和第二耳塞之间已配对过，则当第一耳塞和第二耳塞放置于耳机盒之后，耳机盒上的第一指示灯亮。若第一指示灯不亮，则表明第一耳塞和第二耳塞之间未配对过，此时，用户可以触摸耳机盒上的第二控件，以指示第一耳塞和第二耳塞清除已保存的MAC地址，而后第一耳塞和第二耳塞可以通过扫描等方式建立第一耳塞和第二耳塞之间的蓝牙连接。
在又一种情况下，若第一耳塞和第二耳塞之间已相互保存对方的MAC地址，则第一耳塞和第二耳塞之间已配对过。当第一耳塞和第二耳塞放置于耳机盒之后，第一耳塞和第二耳塞可以清除已保存的MAC地址，从而解除两只耳塞之间的配对关系。而后，在耳机盒开盒，或者用户触摸(例如，轻触、点击或长按等)耳机盒上的第一控件，或者某一只耳塞从耳机盒中取出后，第一耳塞和第二耳塞之间可以通过扫描、广播等方式进行蓝牙配对连接。
由于蓝牙、Wi-Fi等无线通信技术均使用2.4GHz频段，因而若已建立蓝牙配对连接的第一耳塞和第二耳塞支持NFMI，则可以第一耳塞和第二耳塞之间可以切换到NFMI(不使用2.4GHz频段)连接，以降低在2.4GHz频段进行数据传输时的干扰。
此外，第一耳塞和第二耳塞之间还可以通过Wi-Fi等其他近距离无线通信技术建立无线配对连接，本申请实施例不予限定。
需要说明的是，在第一耳塞和第二耳塞建立无线连接后，第一耳塞和第二耳塞之间可以互相保存对方的MAC地址，以表明第一耳塞和第二耳塞作为配对使用的一组/一对设备使用；或者，第一耳塞和第二耳塞可以对应同一身份标识，以表明第一耳塞和第二耳塞作为一对设备协同使用，例如可以同步播放同一音频数据的左声道信号和右声道信号。其中，该身份标识可以是第一耳塞和第二耳塞协商的标识(例如为第一耳塞的MAC地址)；也可以是第一耳塞和第二耳塞与手机连接后，手机设置的标识，还可以是预设的标识，本申请实施例不做限定。
在第一耳塞和第二耳塞建立无线配对连接后，第一耳塞和/或第二耳塞可以声音提示用户TWS耳机间已经建立连接。或者，第一耳塞和/或第二耳塞通过指示灯长亮或闪烁或指示灯为特定的颜色来提示用户TWS耳机之间已经建立连接。或者，第一耳塞和/或第二耳塞通过显示屏显示文字或图标等信息，来提示用户TWS耳机已建立连接。第一耳塞和/或第二耳塞通过振动等其他方式提示用户TWS耳机已建立连接。
在第一耳塞和第二耳塞建立无线配对连接后，第一耳塞可以进入可连接可发现状态，以便可以被手机发现和连接；第二耳塞可以进入不可连接不可发现状态。在不可 连接不可发现状态下，第二耳塞不会被其他设备通过蓝牙检测到，也不会与其他设备建立蓝牙连接。
502、第一耳塞进入与手机的配对状态。
在TWS耳机与手机建立蓝牙配对连接之前，第一耳塞需要先进入与手机的配对状态。其中，第一耳塞可以是TWS耳机中的任意一个耳塞。
在一实施例中，TWS耳机可以包括主耳塞和副耳塞，第一耳塞可以为TWS耳机中的主耳塞，第二耳塞可以为TWS耳机中的副耳塞，手机可以首先建立与主耳塞之间的蓝牙连接。
其中，主耳塞和副耳塞的区分方式可以有多种。例如，默认TWS耳机的右耳塞为主耳塞，左耳塞为副耳塞。再例如，先从耳机盒中拿出的耳塞为主耳塞，后从耳机盒中拿出的耳塞为副耳塞。再例如，先入耳的耳塞为主耳塞，后入耳的耳塞为副耳塞。再例如，TWS耳机中电量较大的耳塞为主耳塞，另一只耳塞为副耳塞。再例如，主耳塞为用户语音等方式指示的耳塞，比如第一耳塞在检测到用户在第一耳塞上的第二控件的触摸操作后，可以确定自己为主耳塞。再例如，本次使用TWS耳机时的主耳塞默认为用户上一次使用时的主耳塞。
需要注意的是，在用户使用TWS耳机的过程中，主、副耳塞的角色可以进行切换。
在用户使用TWS耳机与当前手机进行配对连接时，若用户使用TWS耳机已经与其他电子设备建立了配对关系，且未解除与其他电子设备的配对关系，例如TWS耳机上保存有与其他手机的配对历史(如保存有已配对的其他手机的MAC地址)，则TWS耳机在解除与其他电子设备的配对关系后，才可以进入配对状态。示例性的，当TWS耳机检测到用户长按TWS耳机上的配对键(例如可以是触摸控件024)的操作后，可以解除TWS耳机与其他电子设备的配对关系。再示例性的，在将TWS耳机从耳机盒中取出之前，用户可以长按耳机盒上的配对键，耳机盒可以触发TWS耳机解除与其他电子设备的配对关系。在解除TWS耳机与其他电子设备的配对关系后，第一耳塞和第二耳塞进入可配对状态。
若用户之前未使用TWS耳机与其他电子设备配对过(比如，TWS耳机上未保存有与其他电子设备的配对历史)，则TWS耳机可以自动进入配对状态。
503、手机建立与第一耳塞之间的蓝牙连接。
在第一耳塞进入与手机的配对状态后，第一耳塞与手机之间可以通过一次或多次交互过程确认双方是否支持双发模式，并交换双方的蓝牙地址(例如MAC地址)。手机可以根据自身的能力与第一耳塞建立蓝牙连接。例如，若手机与第一耳塞均支持双发模式，则可以执行本申请实施例中的以下步骤，从而建立手机与TWS耳机之间的双发连接。若手机不支持双发模式，则可以执行监听、转发、NFMI等方案的连接流程。
其中，在建立手机与TWS耳机之间的双发连接的过程中，第一耳塞与手机之间可以先确认双方支持双发模式，再建立蓝牙连接；或者，第一耳塞与手机之间也可以先建立蓝牙连接，再确认双方支持双发模式。
例如，在一实施例中，参见图7，步骤503具体可以包括：
A1、第一耳塞发送第一BLE不可连接广播消息，该第一BLE不可连接广播消息 中包括第一耳塞的MAC地址和第一双发标识(即第一识别信息)，该第一双发标识用于表示第一耳塞支持双发模式，即第一耳塞和第二耳塞可以与手机建立双发连接，手机可以和两个耳塞同时保持两路蓝牙连接。
在第一耳塞和第二耳塞建立配对连接后，第一耳塞即可发送配对广播消息，例如BLE不可连接广播消息，以尽快被手机发现，提高与手机的配对连接效率。
在一种实施方案中，第一耳塞可以通过快速发现方案来发现手机或被手机发现。在快速发现方案中，特定厂商的TWS耳机与特定厂商的手机之间可以协商特定的频段(例如频段1)，双方在特定的频段上发送和检测配对广播消息，以提高发现的效率，从而提高配对连接效率。
例如，该第一BLE不可连接广播消息可以为ADV_NONCONN_IND消息。例如，该双发标识可以为通用唯一识别码(universally unique identifier，UUID)。
需要注意的是，第一耳塞可以多次发送第一BLE不可连接广播消息，以便该消息能够更快、更大概率地被手机检测到。
此外，第一BLE不可连接广播消息中还可以携带有其他信息，例如第一耳塞的名称(例如名称为TWS耳机，或者名称为TWS的左耳塞)、第一耳塞对应的TWS耳机的名称、第一耳塞的设备类型(例如设备类型为TWS耳机)等。
A2、手机在接收到第一BLE不可连接广播消息后，若手机支持双发模式，则向第一耳塞发送第二BLE不可连接广播消息，该第二BLE不可连接广播消息中包括第二双发标识(即第二识别信息)和手机的MAC地址，该第二双发标识用于表示手机支持双发模式，即手机支持与一对耳机中的的两只耳塞均建立蓝牙连接，同时保持两路蓝牙连接。
例如，第二BLE不可连接广播消息可以为ADV_NONCONN_IND消息。手机在根据第一耳塞的第一双发标识确定第一耳塞支持双发模式，且自身也支持双发模式后，可以向第一耳塞发送第二BLE不可连接广播消息，并携带手机自身的MAC地址和第一耳塞的MAC地址，从而将手机的MAC地址通知给第一耳塞。第二BLE不可连接广播消息中还可以包括其他信息，例如第一耳塞的MAC地址。
这样，第一耳塞和手机之间就实现了MAC地址的交换。
A3、第一耳塞接收到手机发送的第二BLE不可连接广播消息后，向手机发送第一BLE可连接广播消息。
在第一耳塞根据手机发送的第一双发标识确定手机也支持双发模式，且第一耳塞和手机交换MAC地址后，第一耳塞可以向手机发送第一BLE可连接广播消息，以请求与手机建立连接。例如，第一BLE可连接广播消息可以为ADV_DIRECT_IND消息或ADV_IND消息。
A4、若手机支持双发模式，则手机显示第一标识，该第一标识用于表示第一耳塞或第一耳塞对应的TWS耳机。
例如，第一标识可以包括以下至少一种：第一耳塞的名称，第一耳塞的图标，第一耳塞的MAC地址，第一耳塞对应的TWS耳机的名称，第一耳塞对应的TWS耳机的图标，第一耳塞和第二耳塞对应的同一身份标识等。示例性的，参见图8A中的800，第一标识可以为TWS耳机的图标和名称。再示例性的，当采用快速发现方案时，参见 图8B，手机可以通过弹窗801来显示第一标标识，从而提醒用户已发现第一标识对应的蓝牙设备；该第一标识包括TWS耳机的图标802、TWS耳机的名称803和TWS耳机的MAC地址804。
在一种实施方案中，第一BLE不可连接广播消息或第一BLE可连接广播消息中可以包括第一耳塞对应的TWS耳机的名称。若手机支持双发模式，则手机可以根据从第一耳塞接收到的TWS耳机的名称显示第一标识，该第一标识包括第一耳塞对应的TWS耳机的名称。
作为步骤A4的一种替换，无论手机是否支持双发模式都可以显示第一标识。若手机支持双发模式，则当用户对第一标识进行操作时，手机可以响应于用户的操作执行双发连接流程。若手机不支持双发模式，则当用户对第一标识进行操作时，手机不响应用户的操作；例如第一标识在手机上的显示为灰色，以提醒用户点击后无响应；再例如第一标识标记为不可用等。
A5、手机检测到用户在第一标识上的操作后，向第一耳塞发送连接成功信息。
手机在检测到用户在第一标识上的操作后，确定用户想要连接手机和第一耳塞，因而可以向第一耳塞发送连接成功信息。
示例性的，参见图8A，用户在第一标识上的操作可以为用户点击TWS耳机的名称的操作。再示例性的，参见图8B，用户在第一标识上的操作可以为用户点击连接控件805的操作。连接成功信息可以是CONNECT_IND消息。在手机向第一耳塞发送连接成功信息后，手机与第一耳塞之间成功建立了配对连接。
可选地，手机接收到第一耳塞发送的第一BLE可连接广播消息后，可以进行鉴权(如合法性验证)、加密等操作，在鉴权完成后，手机向第一耳塞发送连接成功消息。
也就是说，在本申请实施例中，手机和第一耳塞可以先通过第一BLE不可连接广播消息确定双方是否支持双发模式；而后，在用户点击第一标识后，若手机和第一耳塞均支持双发模式，则手机执行双发连接流程。此外，若手机或第一耳塞不支持双发模式，则手机执行转发、监听或NFMI连接流程，此处不予赘述。
在另一实施例中，参见图9，步骤503具体可以包括：
B1、第一耳塞发送第二BLE可连接广播消息，该第二BLE可连接广播消息中包括第一耳塞的MAC地址和第一双发标识，以及第一耳塞的名称或第一耳塞对应的TWS耳机的名称，该第一双发标识用于表示第一耳塞支持双发模式。
在第一耳塞和第二耳塞建立配对连接后，第一耳塞即可发送第二BLE可连接广播消息，以尽快被手机发现，提高与手机的配对连接效率。例如，第二可连接广播消息可以为ADV_IND消息。
另外，第二BLE可连接广播消息中还可以包括第一耳塞的MAC地址、第一耳塞的设备类型等信息。
B2、手机接收到第一耳塞发送的第二BLE可连接广播消息后，若手机支持双发模式，则显示第一标识，该第一标识用于表示第一耳塞或第一耳塞对应的TWS耳机。
若手机支持双发模式，则可以根据第二BLE可连接广播消息中携带的信息显示第一标识，该第一标识可以包括第一耳塞的名称或第一耳塞对应的TWS耳机的名称。
B3、手机检测到用户在第一标识上的操作后，向第一耳塞发送连接成功信息。
其中，连接成功信息中可以包括手机的MAC地址，以便手机可以将自身的蓝牙地址通知给第一耳塞。
在用户点击第一标识后，手机可以向第一耳塞发送连接成功信息，进而建立手机与TWS耳机之间的双发连接。例如，该连接成功信息可以为CONNECT_IND消息。此外，若手机或第一耳塞不支持双发模式，则执行转发、监听或NFMI连接流程。
若手机支持双发模式，则在一种实施方案中，步骤B3中的连接成功信息中可以包括第二双发标识，该第二双发标识用于表示手机支持双发模式。在另一种实施方案中，参见图9，在上述步骤503的B3之后，还包括步骤B4：手机可以通过与第一耳塞之间的连接链路(例如BLE链路)向第一耳塞发送第二双发标识。在另一种实施方案中，在上述步骤B3之前，手机可以在接收到第一BLE可连接广播消息后，向第一耳塞发送第二双发标识，以通知第一耳塞手机也支持双发模式；而后，在手机检测到用户在第一标识上的操作后，再向第一耳塞发送连接成功信息。
在检测到用户在第一标识上的操作后，与上述方案中手机与第一耳塞通过BLE消息建立蓝牙连接不同，在其他方案中，手机可以通过BR/EDR消息建立与第一耳塞的蓝牙连接。例如，在A1-A5描述的方案中，参见图10A，上述步骤A3-A5可以替换为：
C0、手机在接收到第一BLE不可连接广播消息后，若支持双发模式，则显示第一标识，该第一标识用于表示第一耳塞或第一耳塞对应的TWS耳机。
其中，第一BLE不可连接广播消息包括第一耳塞的名称或第一耳塞对应的TWS耳机的名称，手机可以根据第一BLE不可连接广播消息显示第一标识。
C1、若手机检测到用户对第一标识的操作，则向第一耳塞发送寻呼消息。
其中，上述步骤A1中的第一BLE不可连接广播消息可以携带第一耳塞的MAC地址，手机可以根据该MAC地址向第一耳塞发送寻呼消息。
若手机支持双发模式，则在一种实施方案中，手机可以在步骤C1中的寻呼消息中包括第二双发标识，用于表示手机支持双发模式。在另一种实施方案中，在步骤C1之后，手机可以通过与第一耳塞之间的连接链路发送第二双发标识。在另一种实施方案中，在步骤C1之前，手机可以在接收到第一BLE不可连接广播消息后，向第一耳塞发送携带有第二双发标识的信息，以通知第一耳塞手机也支持双发模式；而后，在手机检测到用户在第一标识上的操作后，再向第一耳塞发送寻呼消息。
C2、第一耳塞向手机发送寻呼响应消息。
第一耳塞可以向手机发送寻呼响应消息，从而建立第一耳塞与手机之间的蓝牙配对连接。
再例如，在B1-B3描述的方案中，参见图10B，上述步骤B3可以替换为步骤C1-C2。其中，上述步骤B1中的第二BLE可连接广播消息可以携带第一耳塞的MAC地址，手机可以根据该MAC地址向第一耳塞发送寻呼消息。作为步骤C1的一种替换方式，若手机支持双发模式，则可以在接收到第二BLE可连接广播消息后，向第一耳塞发送携带有第二双发标识的信息，以通知第一耳塞手机也支持双发模式；而后，在手机检测到用户在第一标识上的操作后，再向第一耳塞发送寻呼消息。
其中，步骤C1、C2描述的方案可以用于支持BR/EDR蓝牙配对连接的手机。BR/EDR的寻呼消息和寻呼响应消息等遵循SPP协议；BLE方式的广播消息遵循GATT 协议。
需要注意的是，在手机与第一耳塞建立蓝牙配对连接的过程中，手机与第一耳塞之间还可以协商跳频方式、时钟等链路信息，以便可以通过手机与第一耳塞之间的连接链路传输音乐数据。
在手机与第一耳塞建立蓝牙配对连接后，双方可以互存对方的MAC地址。
在手机与第一耳塞建立蓝牙配对连接后，手机和/或TWS耳机可以通过声音、显示、振动、指示灯等方式提示用户手机已与第一耳塞建立配对连接。示例性的，参见图11，手机可以在状态栏显示第一耳塞的图标1101，表示与第一耳塞建立了蓝牙配对连接。
需要说明的是，在本申请实施例中，第一耳塞可以在与手机建立蓝牙连接之前与第二耳塞建立无线连接，也可以在与手机建立蓝牙连接之后再与第二耳塞建立无线连接，本申请实施例不予限定。
为了兼容蓝牙BR/EDR方式，在上述步骤A1-A5描述的方案中，以及步骤A1-A2、C0-C2描述的方案中，在第一耳塞在步骤A1中发送第一BLE不可连接广播消息的同时，第一耳塞还可以打开BR/EDR方式，通过寻呼扫描或查询扫描来进行发现/被发现。或者，在步骤B1-B3描述的方案中，以及步骤B1-B2、C1-C2描述的方案中，在第一耳塞在步骤B1中发送第二BLE可连接广播消息的同时，第一耳塞还可以打开BR/EDR方式，通过寻呼扫描或查询扫描来进行发现/被发现。
在手机通过BLE方式(如步骤A1，B1的一种方式)确定第一耳塞支持双发模式，或通过BR/EDR方式发现第一耳塞后，在步骤A4、B2或C0的一种实施方案中，手机可以显示一个第一标识。该第一标识可以包括第一耳塞的名称或第一耳塞对应的TWS耳机的名称。
例如，手机通过BLE方式确定第一耳塞支持双发模式，且未通过BR/EDR方式发现第一耳塞，则手机可以显示第一标识。而后，若手机通过BR/EDR方式发现第一耳塞，则手机确定两种方式发现的设备为同一设备，因而仅显示一个第一标识。
再例如，手机通过BLE方式确定第一耳塞支持双发模式，且未通过BR/EDR方式发现第一耳塞，则手机可以暂不显示第一标识；若手机确定自身也支持双发模式，则手机可以显示第一标识。而后，若手机通过BR/EDR方式发现第一耳塞，则手机确定两种方式发现的设备为同一设备，因而仅显示一个第一标识。
又例如，在步骤A4、B2或C0中，若手机通过BR/EDR方式发现第一耳塞，则可以显示第一标识。而后，若手机通过BLE方式发现第一耳塞，且第一耳塞支持双发模式，则手机确定两种方式发现的设备为同一设备，因而仅显示一个第一标识。
再例如，第一耳塞在步骤A2中发送的第一BLE不可连接广播消息，以及第一耳塞在步骤B1中发送的第二BLE可连接广播消息，均不包括第一耳塞的名称和第一耳塞对应的TWS耳机的名称。在步骤A4、B2或C0中，若手机通过BLE方式确定第一耳塞支持双发模式，且未通过BR/EDR方式发现第一耳塞，则手机可以不显示第一标识。而后，若手机通过BR/EDR方式发现第一耳塞，则可以显示该第一标识。
在用户点击该第一标识后，若手机支持双发模式，则执行双发连接流程；若手机不支持双发模式，则执行监听、转发NFMI等连接流程。
在步骤A4、B2或C0的另一种实施方案中，手机可以显示一个第一标识和一个第二标识，该第一标识可以包括第一耳塞的名称或第一耳塞对应的TWS耳机的名称，该第二标识可以包括第一耳塞的MAC地址或TWS耳机的MAC地址。
例如，在步骤A4、B2或C0中，若手机通过第一BLE不可连接广播消息或不带名称的第二BLE可连接广播消息确定第一耳塞支持双发模式，且未通过BR/EDR方式发现第一耳塞，则手机可以根据第一BLE可连接广播消息或根据第二BLE可连接广播消息显示第二标识；若手机确定自身也支持双发模式，则可以显示第一标识。而后，若手机通过BR/EDR方式发现第一耳塞，则手机确定两种方式发现的设备为同一设备，因而可以仍显示该第一标识，并继续显示第二标识。
再例如，在步骤A4、B2或C0中，若手机通过BLE方式确定第一耳塞支持双发模式，且未通过BR/EDR方式发现第一耳塞，则手机可以显示第二标识；若手机确定自身也支持双发模式，则仍显示该第二标识。而后，若手机通过BR/EDR方式发现第一耳塞，则手机可以显示该第一标识，停止显示该第二标识；或者手机可以显示该第一标识和该第二标识。
又例如，在步骤A4、B2或C0中，若手机通过BR/EDR方式发现第一耳塞，则可以显示第一标识。而后，若手机通过BLE配对广播消息确定第一耳塞和手机支持双发模式，则可以显示第一标识和第二标识。
若手机显示第一标识和第二标识，一种情况下，在用户点击该第一标识后，若手机支持双发模式，则执行双发连接流程；若手机不支持双发模式，则执行监听、转发NFMI等连接流程。当用户点击该第二标识时，手机不会执行连接过程。另一种情况下，当用户点击该第一标识时，手机执行监听、转发NFMI等连接流程。当用户点击该第二标识时，手机执行本申请实施例提供的双发连接流程。
在步骤A4、B2或C0的又一种实施方案中，在手机通过BLE方式发现第一耳塞，且第一耳塞支持双发模式后，可以显示一个第一标识；当手机通过BR/EDR方式发现第一耳塞后，手机可以显示一个第三标识。该第一标识和第三标识均可以包括第一耳塞的名称或第一耳塞对应的TWS耳机的名称。其中，第一标识对应双发连接方案，第三标识对应单发连接方案。示例性的，手机的界面示意图可以参见图12，1201表示第一标识，1202表示第三标识。在手机检测到用户在第一标识1201上的点击操作后，若手机也支持双发，则手机与第一耳塞和第二耳塞之间执行本申请实施例提供的双发连接流程；在手机检测到用户在第三标识1202上的点击操作后，手机与第一耳塞和第二耳塞之间执行监听、转发或NFMI连接流程。
此外，在第一耳塞打开BR/EDR可连接可发现状态后，若第一耳塞确定第一耳塞和手机均支持双发模式(例如第一耳塞接收到手机发送的第二双发标识)，则第一耳塞还可以关闭BR/EDR方式。
504、手机通知第一耳塞，手机支持双发模式。
若手机支持双发模式，则手机可以通知第一耳塞，以使得第一耳塞可以执行双发连接流程。例如，该步骤可以是以上步骤B4。需要说明的是，若在步骤503中，手机已经通知过第一耳塞手机支持双发模式(例如在步骤A2中手机向第一耳塞发送第二双发标识)，则步骤504也可以省去。
在一实施例中，在手机建立与第一耳塞之间的蓝牙配对连接后，第一耳塞可以将手机的MAC地址转发给第二耳塞。第二耳塞根据手机的MAC地址建立与手机之间的蓝牙配对连接，且手机保持与第一耳塞之间的蓝牙连接。以下对该方案进行具体说明。
505、手机和第二耳塞建立蓝牙连接。
在第一耳塞确定手机也支持双发模式后，可以执行双发连接流程。第一耳塞可以向手机发送第二耳塞的信息(例如第二耳塞的MAC地址)，并向第二耳塞发送手机的信息(例如手机的MAC地址)，以使得手机和第二耳塞可以通过第一耳塞建立蓝牙连接。
例如，在一种实施方案中，步骤505可以包括：第一耳塞可以向第二耳塞发送连接信息1，该连接信息1中可以包括手机的MAC地址，并指示第二耳塞进入可连接可发现状态。指示第二耳塞进入可连接可发现状态可以是由连接信息1中除手机MAC地址以外的其他内容指示的，如特定的标识；或者通过携带连接信息1的特定消息或消息类型指示的；或者是手机的MAC地址，因为第二耳塞中有第一耳塞的蓝牙地址，收到第一耳塞发来的其他MAC地址，则第二耳塞可以识别出来，从而进入可连接可发现状态，与手机连接。第二耳塞可以根据连接信息1建立与手机之间的蓝牙连接，且手机与第一耳塞之间保持蓝牙连接。在第二耳塞建立与手机之间的蓝牙连接后，由于第一耳塞与手机之前已建立了蓝牙连接，因而实现了手机与TWS耳机的两只耳塞之间的双发连接。
第一耳塞接收到手机发送的第二双发标识后，确定手机也支持双发模式，因而可以执行双发连接的流程。在双发连接流程的过程中，由于在第一耳塞与手机建立蓝牙配对连接后，第一耳塞中保存有手机的MAC地址，因而第一耳塞可以通过连接信息1将手机的MAC地址转发给第二耳塞，以便于第一耳塞根据手机的MAC地址建立与手机之间的蓝牙配对连接。
此外，连接信息1中还可以包括手机与第一耳塞之间的跳频方式、时钟等链路信息，以使得第二耳塞可以根据手机与第一耳塞之间的链路信息建立链路，从而与手机与第一耳塞之间的链路保持同步，使得第一耳塞和第二耳塞能够播放播放立体声音乐。
其中，当第一耳塞和第二耳塞之间为BR/EDR连接时，第一耳塞可以根据SPP协议向第二耳塞发送连接信息1；当第一耳塞和第二耳塞之间为BLE连接时，第一耳塞可以根据GATT协议向第二耳塞发送连接信息1。
在一实施例中，在步骤505中，第二耳塞可以主动连接手机。参见图13，步骤505具体可以包括：
D0、第一耳塞向第二耳塞发送连接信息1，以指示第二耳塞可连接手机。
D1、第二耳塞接收到连接信息1后，进入可连接可发现状态，以便可以主动连接其他设备或被其他设备连接。
D2、第二耳塞根据连接信息1，向手机发送连接请求信息。
具体的，第二耳塞可以根据连接信息1中的手机的MAC地址等信息，主动发起对手机的连接。该连接请求信息中可以包括第二耳塞的MAC地址，以使得连接请求信息的接收者可以获知请求建立连接的设备的身份。
需要说明的是，在本文的步骤505中，手机、第一耳塞、第二耳塞之间交互的信 息(例如，连接信息、通知信息、连接成功信息等)可以是遵循GATT协议的BLE消息，也可以是遵循SPP协议的BR/EDR消息，本申请实施例不予限定。
例如，该连接请求信息可以是BLE的ADV_DIRECT_IND消息或ADV_IND消息等；或者，该连接请求可以是BR/EDR的page消息等。
D3、第二耳塞向第一耳塞发送通知信息1。
其中，通知信息1可以用于通知第一耳塞，第二耳塞将请求连接手机，或者第二耳塞已进入可连接可发现状态。
需要注意的是，步骤D2可以在步骤D3之前，也可以在步骤D3之后，本申请实施例不予限定。
D4、第一耳塞在接收到第二耳塞发送的通知信息1后，向手机发送通知信息2。
其中，通知信息2中可以包括第二耳塞的MAC地址，可以表明第二耳塞与第一耳塞配对使用，使得手机获知请求与手机连接的第一耳塞的配对设备的身份。通知信息2可以用于通知手机，第二耳塞将请求连接手机，或者第二耳塞已进入可连接可发现状态，手机可连接第二耳塞。
需要注意的是，步骤D2可以在步骤D4之前，也可以在步骤D4之后，本申请实施例不予限定。
当手机接收到通知信息2中的第二耳塞的MAC地址后，可以确定第一耳塞和第二耳塞作为一对设备使用。
D5、手机接收到通知信息2和连接请求信息后，向第二耳塞发送连接成功信息。
具体的，手机在接收到第二耳塞发送的连接请求信息后，若确定连接请求信息中的MAC地址，与第一耳塞发送的通知信息2中的第二耳塞的MAC地址一致，则可以表明请求与手机建立连接的设备是第一耳塞指示的设备，因而手机可以向第二耳塞发送连接成功信息，从而成功建立与第二耳塞之间的蓝牙连接，实现手机与TWS耳机的双发连接。
例如，与连接请求信息相对应，连接成功信息可以是BLE的CONNECT_IND消息，或者BR/EDR的page response消息等。
在另一实施例中，作为上述步骤D2-D4的一种替换，第二耳塞可以通过第一耳塞的转发，将连接请求信息发送给手机，比如步骤D2的连接请求信息通过第一耳塞转发。进一步地，还可以在转发过程中，第二耳塞将通知信息1发送给第一耳塞，第一耳塞将通信信息2发送给手机。
在另一实施例中，第一耳塞也可以在步骤503中将第二耳塞的MAC地址通知给手机，以使得手机获知第一耳塞和第二耳塞的配对关系。例如，第一耳塞可以通过BLE不可连接广播消息、BLE可连接广播消息等将第二耳塞的MAC地址也发送给手机，以表明第一耳塞和第二耳塞配对使用，指示手机可连接第二耳塞。这样，在上述D0-D5描述的方案中，步骤D3和D4也可以省去；并且在步骤D5中，手机接收到第二耳塞发送的连接请求信息后，若确定第一耳塞在步骤503中发送的第二耳塞的MAC地址，与连接请求信息中的MAC地址一致，则向第二耳塞发送连接成功信息，从而成功建立与第二耳塞之间的蓝牙连接，实现手机与TWS耳机的双发连接。
在另一实施例中，在步骤505中，手机可以主动连接第二耳塞。参见图14，步骤 505具体可以包括：
E0、第一耳塞向第二耳塞发送连接信息1，以指示第二耳塞可连接手机。
E1、第二耳塞接收到连接信息1后，进入可连接可发现状态，以便可以主动连接其他设备或被其他设备连接。
E2、第二耳塞向第一耳塞发送通知消息3。
其中，通知消息3可以用于通知第一耳塞，第二耳塞已进入可连接可发现状态，或者第二耳塞可以被连接。
E3、第一耳塞在接收到第二耳塞发送的通知信息3后，向手机发送通知信息4。
其中，通知信息4中包括第二耳塞的MAC地址，可以表明第二耳塞与第一耳塞配对使用。通知信息4可以用于通知手机主动连接第二耳塞；或者第二耳塞已进入可连接可发现状态。第一耳塞可以在通知信息3中接收第二耳塞的MAC地址，也可以在之前与第二耳塞进行无线连接时获得第二耳塞的MAC地址。
E4、手机接收到通知信息4后，向第二耳塞发送连接请求信息。
具体的，手机可以根据通知信息4中的第二耳塞的MAC地址，向第二耳塞发送连接请求信息。连接请求信息中可以包括手机的MAC地址，以使得连接请求信息的接收者可以获知请求建立连接的设备的身份。
E5、第二耳塞在接收到连接请求信息后，向手机发送连接成功信息。
具体的，第二耳塞在接收到连接请求信息后，若确定连接请求信息中手机的MAC地址，与第一耳塞发送的连接信息1中手机的MAC地址一致，则可以表明请求与第二耳塞建立连接的设备是第一耳塞指示的设备，因而第二耳塞可以向手机发送连接成功信息。
在另一实施例中，第一耳塞也可以在步骤503中将第二耳塞的MAC地址通知给手机，以使得手机获知第一耳塞和第二耳塞的配对关系。例如，第一耳塞可以通过第一BLE不可连接广播消息、第一可连接广播消息、第二可连接广播消息等将第二耳塞的MAC地址也发送给手机，以表明第一耳塞和第二耳塞配对使用，且手机可以连接第二耳塞。这样，在上述步骤E0-E5描述的方案中，步骤E2和E3也可以省去，在步骤E4中，手机可以根据第一耳塞在步骤503中发送的第二耳塞的MAC地址，向第二耳塞发送连接请求信息。
在步骤505中建立手机与第二耳塞之间的配对连接后，手机与TWS耳机之间即实现的双发连接，此时手机和/或TWS耳机可以通过声音、显示、振动、指示灯等方式提示用户已与TWS耳机建立配对连接。示例性的，参见图15中的(a)，手机可以在状态栏显示TWS耳机的图标1501，表示与TWS耳机建立了蓝牙配对连接。再示例性的，参见图15中的(b)，TWS耳机的显示屏上显示有手机的图标1502，表示TWS耳机与手机建立了配对连接。
再例如，在另一种实施方案中，步骤505可以包括：第一耳塞可以向手机发送连接信息2，该连接信息2中可以包括第二耳塞的MAC地址，可以表明第二耳塞与第一耳塞配对使用，以指示手机可以连接第二耳塞。手机可以根据连接信息2建立与第二耳塞之间的蓝牙连接，且手机与第一耳塞之间保持蓝牙连接。
在该方案中，在第一耳塞与第二耳塞建立蓝牙配对连接后，第一耳塞中保存有第 二耳塞的MAC地址，因而第一耳塞可以通过连接信息2将第二耳塞的MAC地址转发给手机，以便于第二耳塞根据手机的MAC地址建立与手机之间的蓝牙配对连接。手机接收到第一耳塞发送的连接信息2中第二耳塞的MAC地址后，可以确定第一耳塞和第二耳塞作为一对设备使用。
在一实施例中，在步骤505中，手机可以主动连接第二耳塞。参见图16，步骤505具体可以包括：
F0、第一耳塞向手机发送连接信息2，以指示第二耳塞与第一耳塞配对使用。
手机接收到连接信息2后，获知可连接第二耳塞。
F1、手机在接收到连接信息2后，向第一耳塞发送通知信息5。
F2、第一耳塞接收到通知信息5后，向第二耳塞发送通知信息6，以指示第二耳塞可连接手机。
其中，通知消息6中可以包括手机的MAC地址，第二耳塞可以根据通知信息6获知可以连接手机。
可以理解地，第一耳塞可以不等到收到通知信息5，就向第二耳塞发送通知信息6，即步骤F1可以省去。
F3、第二耳塞在接收到通知信息6后，进入可连接可发现状态，以便可以与其他设备进行连接。
也就是说，在步骤F1-F3中，手机可以通过第一耳塞通知第二耳塞进入可连接可发现状态，以便可以与手机进行连接。
F4、手机在接收到连接信息2后，向第二耳塞发送连接请求信息。
F5、第二耳塞在接收到通知信息6和连接请求信息后，向手机发送连接成功信息。
若第二耳塞确定连接请求信息中手机的MAC地址与通知信息6中的手机的MAC地址一致，则可以表明请求与第二耳塞建立连接的设备是第一耳塞指示的设备，因而第二耳塞可以向手机发送连接成功信息。
其中，关于步骤F0-F5的具体实现过程可以参见步骤D0-D5的相关描述，此处不予赘述。
在另一实施例中，作为上述步骤F1-F4的一种替换，手机可以通过第一耳塞的转发，将连接请求信息发送给第二耳塞。
在另一实施例中，在步骤505中，第二耳塞可以主动连接手机。参见图17，步骤505可以包括：
G0、第一耳塞向手机发送连接信息2，以指示第二耳塞与第一耳塞配对使用。
手机接收到连接信息2后，获知可连接第二耳塞。
G1、手机接收到连接信息2后，向第一耳塞发送通知信息7。
G2、第一耳塞接收到通知信息7后，向第二耳塞发送通知信息8，以指示第二耳塞可连接耳机。
其中，通知消息8中可以包括手机的MAC地址。
G3、第二耳塞在接收到通知信息8后，进入可连接可发现状态，以便可以与其他设备进行连接。
也就是说，在步骤G1-G3中，手机可以通过第一耳塞通知第二耳塞进入可连接可 发现状态，以便可以与手机进行连接。
G4、第二耳塞根据通知信息8，向手机发送连接请求信息。
其中，手机可以根据通知消息8中手机的MAC地址，向手机发送连接请求信息。
G5、手机在接收到连接请求信息后，向第二耳塞发送连接成功信息。
若手机确定连接信息2中第二耳塞的MAC地址，与第一耳塞发送的连接请求信息中第二耳塞的MAC地址一致，则可以表明请求与手机建立连接的设备是第一耳塞指示的设备，因而手机可以向第二耳塞发送连接成功信息。
其中，关于步骤G0-G5的具体实现过程可以参见步骤E0-E5的相关描述，此处不予赘述。
此外，在步骤505之后，手机和/或第二耳塞还可以通知第一耳塞，手机和第二耳塞已建立蓝牙连接。
可以理解的是，手机和第二耳塞通过第一耳塞的媒介作用建立蓝牙连接的方式还可以有其他方式，以上方式仅为举例说明，并不作为具体限定。
在建立手机与第二耳塞之间的配对连接后，手机可以保持分别与第一耳塞和第二耳塞之间的蓝牙连接，从而保持手机与TWS耳机之间的双发连接。
在手机实现与第一耳塞和第二耳塞的双发连接后，手机可以关联存储第一耳塞和第二耳塞的MAC地址，以表明第一耳塞和第二耳塞是作为一对设备使用的。
在建立双发连接后，第一耳塞与第二耳塞之间可以保持无线连接，也可以断开无线连接。即，可选地，在步骤505之后，参见图5，该方法还可以包括：
506、第一耳塞和第二耳塞之间断开无线连接。
在建立双发连接后，手机可以分别向第一耳塞和第二耳塞发送音频数据，第一耳塞和第二耳塞同步播放对应声道的音频信号。例如，用户可以使用第一耳塞和第二耳塞播放音乐。
可以理解的是，若用户先启动播放音乐，后点击第一耳塞的第一标识从而建立手机与TWS的双连接；则在建立TWS耳机的双连接后，才使用TWS耳机播放音乐。若用户先点击第一耳塞的第一标识从而建立手机与TWS的双连接，后启动播放音乐；则在用户启动播放音乐后，即可使用TWS耳机播放音乐。
在一实施例中，手机可以向第一耳塞和第二耳塞均发送立体声音频数据(包括左声道数据和右声道数据)；第一耳塞和第二耳塞分别从中提取一个对应声道的音频数据进行播放。
在另一实施例中，第一耳塞和第二耳塞可以分别从手机接收一个对应声道的音频数据进行播放。在该方案中，第一耳塞和第二耳塞从手机接收的音频数据量少，音频码率低，因而可以减小无线环境被干扰的概率和传输时延；并且，还可以减少每只耳塞射频收信机的工作时间，降低耳塞的功耗。
此外，在播放音乐的过程中，用户可以通过在耳塞上的触摸操作、在手机上的触发操作或者通过语音指示暂停、播放、上一首、下一首等，手机和TWS耳机之间可以通过双发连接及时响应和处理。并且，TWS耳机上的MIC采集到的语音数据，还可以通过每只耳塞各自与手机之间的连接通道发送给手机。
以上实施例是以发现过程中，第一耳塞发送BLE的Primary广播消息为例进行说 明的，第一耳塞也可以发送Secondary广播消息以使得第一耳塞被手机发现。例如，作为步骤B2中ADV_IND该Primary广播消息的替换，第一耳塞可以发送ADV_EXT_IND消息(Primary广播消息)，以及AUX_ADV_IND消息、AUX_SCAN_RSP消息、AUX_SYNC_IND消息等一系列的Secondary广播消息。与发送Secondary广播消息相比，第一耳塞发送Primary广播消息，能够更快地被手机发现，从而提高与手机的连接效率。
此外，手机和第一耳塞之间还可以通过其他方式进行发现。例如，用户在打开手机的蓝牙功能后，还可以开启蓝牙搜索功能，此时手机进入蓝牙扫描状态，并跳频扫描其他设备；第一耳塞可以跳频发送配对广播消息；当手机和第一耳塞跳频到同一频段时，手机检测到第一耳塞的配对广播消息，从而发现第一耳塞，进而与第一耳塞建立蓝牙连接。而后，手机和第一耳塞可以执行以上实施例中的其他步骤。
以上主要阐述了首次建立手机与TWS耳机的双发连接过程，后续再次建立该手机与该TWS耳机的双发连接时，在一种实施方案中，TWS耳机和手机之间可以重新执行本申请以上实施例提供的连接方法。在另一种实施方案中，TWS耳机可以自动回连到手机，比如不需要执行上述双方表明各自支持双发模式的等步骤，从而可以提高连接效率，以下进行举例说明。
例如，在一实施例中，手机上保存有与第一耳塞和第二耳塞的配对历史，手机在接收到第一耳塞的广播消息后，确定已与第一耳塞和第二耳塞配对，从而自动建立与第一耳塞和第二耳塞之间的双发连接。例如，手机上保存有相关联的第一耳塞和第二耳塞的MAC地址，手机可以根据该MAC地址直接寻呼第一耳塞和第二耳塞，建立与第一耳塞和第二耳塞之间的双发连接。再例如，手机根据第一耳塞的MAC地址自动寻呼第一耳塞，从而建立与第一耳塞之间的蓝牙连接，手机和第二耳塞通过第一耳塞转发的手机或第二耳塞的MAC地址建立蓝牙连接，从而实现双发连接。再例如，手机接收到第一耳塞的配对广播消息后，根据保存的MAC地址确定已与第一耳塞配对，从而建立与第一耳塞之间的蓝牙连接；同样地，手机可以建立与第二耳塞之间的蓝牙连接，从而实现双发连接。
在另一实施例中，第一耳塞和第二耳塞上保存有手机的MAC地址，表明TWS耳机已与手机配对，因而第一耳塞和第二耳塞可以根据手机的MAC地址直接寻呼手机，从而建立第一耳塞、第二耳塞与手机之间的双发连接。
在另一实施例中，第一耳塞上保存有手机的MAC地址，并将手机的MAC地址转发给第二耳塞，第一耳塞和第二耳塞检测到手机的配对广播后，与手机建立蓝牙连接。
在建立手机与TWS耳机的双发连接后，后续若需要建立手机与其他TWS耳机之间的双发连接，或者需要建立其他手机与TWS耳机之间的双发连接，则可以重新执行上述首次建立双发连接的流程。
在另一实施例中，用户使用第一耳塞听音乐，第一耳塞与手机之间建立了蓝牙连接，第一耳塞处于单耳模式；在用户想要使用一对TWS耳机时，TWS耳机可以切换为双耳模式。在一种方案中，第一耳塞和第二耳塞之间建立无线连接，第二耳塞和手机通过第一耳塞建立蓝牙连接，从而通过双发连接通道进行音乐播放。在另一种方案中，手机和TWS耳机执行上述实施例中首次建立双发连接的流程，重新建立第一耳塞 与手机之间的蓝牙连接，并建立第二耳塞与手机之间的蓝牙连接，从而通过双发连接通道进行音乐播放。在建立手机与TWS耳机的双发连接后，用户可以通过两只TWS耳塞播放立体声音乐。若用户后续只使用一只TWS耳塞，则不被使用的另一只耳塞可以保持与手机之间的蓝牙连接；或者，另一只耳塞也可以断开与手机之间的蓝牙连接，从而切换为单耳模式，例如当另一只耳塞出耳时，手机可以断开另一只耳塞与手机之间的蓝牙连接。
