具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请技术方案进行介绍说明之前，首先对蓝牙技术的一些背景知识进行介绍说明。
图1示例性示出了蓝牙设备的状态图。
查询状态(inquiry state)。一旦设备想发现新的设备，就会进入查询状态，此时，该设备就向规定范围内的所有设备广播出其查询包(ID packet)，包中包含了IAC(Inquiry Access Code，查询访问码)。通过使用查询跳频序列把包发送出去。在查询状态的设备也可以接收查询回复(FHS packets)，但是，该设备不会对这些包进行确认。
查询扫描状态(inquiry scan state)。当设备想接收查询包时，就会进入查询扫描状态。扫描是根据查询跳频序列进行的。
寻呼状态(page state)。当一个设备搜索其他设备时所进入的状态。该设备使用寻呼跳频序列(page hopping sequence)发送一个寻呼包(ID packet)，用来通知其他设备，它打算了解其他设备及其服务。
寻呼扫描状态(page scan state)。在寻呼扫描状态下，设备监听包含自己的DAC(Device Access Code，设备访问码)的寻呼序列。一旦设备希望接收寻呼数据包时，就会进入寻呼扫描状态，扫描将按照寻呼跳频序列进行，如果设备接收了一个寻呼包，就会进入从设备响应状态(slave response state)。
同步训练状态(synchronization train state)和同步扫描状态(synchronization scan state)与本申请技术方案相关性不大，故不作赘述。
当两个设备需要建立蓝牙链路的时候，一个设备进入寻呼状态，另一个设备进入寻呼扫描状态，两个设备使用相同的寻呼跳频序列，当跳到同样的频点上的时候，这两个设备之间就建立了蓝牙链路。我们将发起寻呼的设备称为主设备(master device)，进行寻呼扫描的设备称为从设备(slave device)。
如图2所示，其示例性示出了蓝牙链路建立过程的流程图。该过程可以包括如下表1所示的6个步骤(S1～S6)：
表1
Figure PCTCN2022085146-appb-000001
蓝牙系统的基带层中定义了多种不同的包类型(packet type)，更高一些的层使用这些包来构成高层PDU(Protocol Data Unit，协议数据单元)。上述包类型包括：ID、NULL、POLL、FHS(Frequency Hop Synchronization，跳频同步)、DM1；在同步链路(Synchronous Connection Oriented link，简称SCO)和异步链路(Asynchronous Connectionless Link，简称ACL)中，都定义了上述这些包。DH1、AUX1、DM3、DH3、DM5、DH5仅仅在异步链路(ACL)中作了定义。HV1、HV2、HV3、DV仅仅在同步链路(SCO)中作了定义。
在蓝牙链路建立过程中，主要涉及ID、FHS和POLL这3种包类型。
ID包是一个用于寻呼、查询和响应过程的68位的数据包，主要由设备访问码(DAC)或者查询访问码(IAC)组成。
FHS包是一个特殊的控制包，其中包含了设备的蓝牙设备地址(Bluetooth Device Address)以及源设备的时钟信息。它包含144个信息位和16位的CRC(Cyclic Redundancy Check，循环冗余校验)码。Payload(载荷)采用的是2/3前向纠错(Forward Error Correction，简称FEC)编码，可以使得payload(载荷)的总长度达到240位。FHS包覆盖单一的时隙。
POLL包类似于NULL包(即空包)，NULL包是一个长度为126位的包，仅由信道访问码(Channel Access Code，CAC)和包头构成，用来返回连接信息给源设备，NULL包不必被确认。POLL包与NULL包的区别在于，POLL包需要来自目的设备的确认。一旦收到主设备的POLL包，从设备必须发回一个包进行响应。
在上述步骤S1中，主设备发送高频率的ID包，从软件上看使用最高的优先级，从空口上看占用很高的带宽，一般不支持并发的寻呼过程。因此，目前相关技术仅支持蓝牙的串行连接。在一个蓝牙设备需要连接多个目标设备的时候，必须先连接一个目标设备，然后再连接另一个目标设备。如果第一个目标设备没有打开蓝牙，或者超出可连接的范围，则需要等到连接超时，才能开始连接另一个蓝牙设备。整体需要的时间比较长，效率较低，影响用户体验。
本申请提供了一种蓝牙链路建立方法，主蓝牙设备通过副蓝牙设备作为其代理，向目标设备发起寻呼，从而能够有效克服单个蓝牙设备无法同时向多个目标设备发起寻呼的限制，实现主蓝牙设备向一个目标设备发起寻呼，与此并行的，副蓝牙设备作为主蓝牙设备的代理向另一个目标设备发起寻呼，从而实现并行寻呼两个目标设备，缩短建立多个蓝牙链路所需的耗时，提升效率。
图3示出了本申请一个实施例提供的方案实施环境的示意图。该方案实施环境可以包括：主蓝牙设备31、副蓝牙设备32、第一目标设备33和第二目标设备34。
主蓝牙设备31是发起蓝牙连接的设备，主蓝牙设备31需要与第一目标设备33和第二目标设备34分别建立蓝牙连接。
在本申请实施例中，主蓝牙设备31与第一目标设备33和第二目标设备34之间的连接建立过程，可以并行执行。一方面，主蓝牙设备31自身向第一目标 设备33发起寻呼，与第一目标设备33建立第一蓝牙链路；另一方面，主蓝牙设备31通过副蓝牙设备32作为其代理设备，由副蓝牙设备32向第二目标设备34发起寻呼，然后在寻呼成功之后，主蓝牙设备31与第二目标设备34建立第二蓝牙链路。这样就克服了单个设备不支持并发的寻呼过程的限制，实现高效的并行连接。
上述主蓝牙设备31、副蓝牙设备32、第一目标设备33和第二目标设备34可以是任何支持蓝牙功能(如具备蓝牙芯片)的电子设备，包括但不限于耳机、手机、平板电脑、可穿戴设备、笔记本电脑、车载终端设备等。
在一示例性应用场景中，如图4所示，主蓝牙设备31和副蓝牙设备32可以是一副耳机的左右两个耳机。主蓝牙设备为主蓝牙耳机，副蓝牙设备为副蓝牙耳机。例如，主蓝牙设备31(或称为主蓝牙耳机)为左耳机，副蓝牙设备32(或称为副蓝牙耳机)为右耳机；或者，主蓝牙设备31(或称为主蓝牙耳机)为右耳机，副蓝牙设备32(或称为副蓝牙耳机)为左耳机。可选地，左右两个耳机哪个作为主蓝牙设备31，哪个作为副蓝牙设备32，可以由两个耳机协商确定，也可以默认配置设定，本申请对此不作限定。
示例性地，某一用户具有一副TWS(True Wireless Stereo，真无线立体声)蓝牙耳机和2个手机(记为手机#A和手机#B)。在初始状态下，左右两个耳机在耳机盒内，且与手机#A和手机#B之间均没有蓝牙连接。用户打开耳机盒，两个耳机可以采用本申请提供的技术方案，一方面主耳机(如左耳机)自身向手机#A发起寻呼，与手机#A建立蓝牙链路，另一方面主耳机(如左耳机)通过副耳机(如右耳机)作为其代理设备，由副耳机(如右耳机)向手机#B发起寻呼，然后在寻呼成功之后，主耳机(如左耳机)与手机#B建立蓝牙链路。通过这种并行连接的方式，能够实现耳机开盒后，高效快速地回连两个目标设备。
当然，在一些其他应用场景中，上述主蓝牙设备31和副蓝牙设备32还可以是一组音箱或者其他蓝牙设备，本申请对此不作限定。
图5示出了本申请一个实施例提供的建立蓝牙链路的方法的流程图。该方法可应用于图3所示的方案实施环境中，该方法可以包括以下几个步骤(510～540)：
步骤510，主蓝牙设备向副蓝牙设备发送连接通知，该连接通知用于指示副蓝牙设备作为主蓝牙设备的代理，向第二目标设备发起寻呼。
为了实现主蓝牙设备与副蓝牙设备之间的通信，主蓝牙设备和副蓝牙设备之间可以建立有蓝牙连接。可选地，在本申请实施例中，将主蓝牙设备与副蓝牙设备之间的蓝牙连接称为设备间蓝牙链路，主蓝牙设备通过该设备间蓝牙链路，向副蓝牙设备发送连接通知。
由于单个设备不支持并发的寻呼过程，因此主蓝牙设备正在寻呼第一目标设备的过程中，可以通过副蓝牙设备作为其代理设备，向第二目标设备发起寻呼，这样主蓝牙设备就可以一方面自身向第一目标设备发起寻呼，并借助于副蓝牙设备向第二目标设备发起寻呼，实现并行寻呼两个目标设备。
可选地，连接通知中包括第二目标设备的DAC，使得副蓝牙设备获知主蓝牙设备期望和哪个设备建立蓝牙链路。
步骤520，副蓝牙设备向第二目标设备发起寻呼。
副蓝牙设备接收来自主蓝牙设备的连接通知之后，向第二目标设备发起寻呼。
在一示例性实施例中，副蓝牙设备向第二目标设备发送寻呼消息；若副蓝牙设备接收到来自第二目标设备的从设备第一寻呼响应，则副蓝牙设备向第二目标设备发送主设备寻呼响应；之后，若副蓝牙设备接收到来自第二目标设备的从设备第二寻呼响应，则副蓝牙设备确定寻呼第二目标设备成功。也即，副蓝牙设备执行上述图2和表1所示的步骤S1～S4的过程。后续，由主蓝牙设备执行上述图2和表1所示的步骤S5～S6，从而建立主蓝牙设备与第二目标设备之间的第二蓝牙链路。
对于这种方式，若副蓝牙设备没有接收到来自第二目标设备的从设备第一寻呼响应，或者副蓝牙设备没有接收到来自第二目标设备的从设备第二寻呼响应，则副蓝牙设备确定寻呼第二目标设备失败。在寻呼第二目标设备失败的情况下，副蓝牙设备可以向主蓝牙设备发送寻呼失败通知，该寻呼失败通知用于指示副蓝牙设备寻呼第二目标设备失败。主蓝牙设备接收到来自副蓝牙设备的寻呼失败通知之后，便可获知副蓝牙设备寻呼第二目标设备失败。后续，如果主蓝牙设备还想和第二目标设备建立蓝牙链路，则可以自己向第二目标设备发起寻呼。
另外，如果由副蓝牙设备执行上述步骤S3向第二目标设备发送主设备寻呼响应，由于该主设备寻呼响应中需要携带实际与第二目标设备建立连接的设备(也即主蓝牙设备)的相关信息，因此，副蓝牙设备在向第二目标设备发送主设备寻呼响应之前，需要先获取主蓝牙设备的相关信息。例如，主蓝牙设备向副蓝牙设备发送的连接通知中，可以携带主蓝牙设备的相关信息。或者，副蓝牙设备在接收到来自第二目标设备的从设备第一寻呼响应之后，向主蓝牙设备发送信息获取请求，该信息获取请求用于请求获取主蓝牙设备的相关信息；相应地，主蓝牙设备接收到该信息获取请求之后，向副蓝牙设备发送主蓝牙设备的相关信息。当然，在一些其他实施例中，副蓝牙设备还可以在其他合适的时机，获取主蓝牙设备的相关信息，本申请对此不作限定。另外，主蓝牙设备的相关信息是指主设备寻呼响应中需要携带的信息，包括但不限于以下至少一项：LAP(LAN Access Point，局域网接入点)、UAP(Upper Address Portion，高位地址部分)、NAP(Non-significant Address Portion，非重要地址部分)、设备类型、设备地址(LT_ADDR(Logical Transport Access Request Address，逻辑传输访问请求地址))、时钟信息、寻呼扫描模式。
在另一示例性实施例中，副蓝牙设备向第二目标设备发送寻呼消息；若副蓝牙设备接收到来自第二目标设备的从设备第一寻呼响应，则副蓝牙设备确定寻呼第二目标设备成功。也即，副蓝牙设备执行上述图2和表1所示的步骤S1～S2的过程。后续，由主蓝牙设备执行上述图2和表1所示的步骤S3～S6，从而建立 主蓝牙设备与第二目标设备之间的第二蓝牙链路。
对于这种方式，若副蓝牙设备没有接收到来自第二目标设备的从设备第一寻呼响应，则副蓝牙设备确定寻呼第二目标设备失败。在寻呼第二目标设备失败的情况下，副蓝牙设备可以向主蓝牙设备发送寻呼失败通知，该寻呼失败通知用于指示副蓝牙设备寻呼第二目标设备失败。主蓝牙设备接收到来自副蓝牙设备的寻呼失败通知之后，便可获知副蓝牙设备寻呼第二目标设备失败。后续，如果主蓝牙设备还想和第二目标设备建立蓝牙链路，则可以自己向第二目标设备发起寻呼。
另外，对于这种方式，副蓝牙设备不需要执行上述步骤S3向第二目标设备发送主设备寻呼响应，而是由主蓝牙设备执行上述步骤S3向第二目标设备发送主设备寻呼响应，因此上文介绍的主蓝牙设备的相关信息可以不必提供给副蓝牙设备。
步骤530，若寻呼第二目标设备成功，则副蓝牙设备向主蓝牙设备发送连接信息，该连接信息用于供主蓝牙设备与第二目标设备进行接续通信。
可选地，副蓝牙设备通过上述设备间蓝牙链路，向主蓝牙设备发送连接信息。
所谓接续通信是指主蓝牙设备不需要再向第二目标设备发起寻呼，可以直接利用该连接信息与第二目标设备进行通信，如交换建立蓝牙链路所需的必要信息，实现主蓝牙设备与第二目标设备之间建立蓝牙链路。
可选地，连接信息包括时钟同步信息，该时钟同步信息用于使得主蓝牙设备与第二目标设备在相同的频点进行通信。例如，时钟同步信息可以是时钟偏移信息，主蓝牙设备根据该时钟偏移信息，能够调整自己的时钟，以使得主蓝牙设备与第二目标设备能够在相同的频点进行通信。
步骤540，主蓝牙设备基于连接信息与第二目标设备建立第二蓝牙链路。
主蓝牙设备接收来自副蓝牙设备的连接信息之后，基于该连接信息与第二目标设备建立第二蓝牙链路。在本申请实施例中，将主蓝牙设备与第二目标设备之间的蓝牙链路称为第二蓝牙链路。
在一示例性实施例中，如果由副蓝牙设备执行上述步骤S3向第二目标设备发送主设备寻呼响应，那么主蓝牙设备基于连接信息确定目标频点，在目标频点向第二目标设备发送LMP(Link Manager Protocol，链路管理协议)特性交换请求，该LMP特性交换请求中包括主蓝牙设备的特性信息，接收来自第二目标设备的LMP特性交换响应，该LMP特性交换响应中包括第二目标设备的特性信息，保存第二目标设备的特性信息，并向第二目标设备发送LMP建立完成消息，该LMP建立完成消息用于指示蓝牙链路建立完成。也即，主蓝牙设备基于连接信息确定目标频点之后，执行上述图2和表1所示的步骤S5～S6的过程，完成蓝牙链路的建立过程。
在另一示例性实施例中，如果由主蓝牙设备执行上述步骤S3向第二目标设备发送主设备寻呼响应，那么主蓝牙设备基于连接信息确定目标频点，在目标频点向第二目标设备发送主设备寻呼响应。若接收到来自第二目标设备的从设 备第二寻呼响应，则向第二目标设备发送LMP特性交换请求，该LMP特性交换请求中包括主蓝牙设备的特性信息。接收来自第二目标设备的LMP特性交换响应，该LMP特性交换响应中包括第二目标设备的特性信息，保存第二目标设备的特性信息，并向第二目标设备发送LMP建立完成消息，该LMP建立完成消息用于指示蓝牙链路建立完成。也即，主蓝牙设备基于连接信息确定目标频点之后，执行上述图2和表1所示的步骤S3～S6的过程，完成蓝牙链路的建立过程。
可选地，主蓝牙设备向第一目标设备发起寻呼，若寻呼第一目标设备成功，则主蓝牙设备与第一目标设备建立第一蓝牙链路；其中，第二蓝牙链路的建立过程与第一蓝牙链路的建立过程并行执行。在本申请实施例中，将主蓝牙设备与第一目标设备之间的蓝牙链路称为第一蓝牙链路，该第一蓝牙链路的建立过程可以参考图2和表1所示的步骤S1～S6的过程。
综上所述，本申请实施例提供的技术方案，主蓝牙设备通过副蓝牙设备作为其代理，向目标设备发起寻呼，从而能够有效克服单个蓝牙设备无法同时向多个目标设备发起寻呼的限制，实现主蓝牙设备向一个目标设备发起寻呼，与此并行的，副蓝牙设备作为主蓝牙设备的代理向另一个目标设备发起寻呼，从而实现并行寻呼两个目标设备，缩短建立多个蓝牙链路所需的耗时，提升效率。
另外，对于上文介绍的两种方式，如果由副蓝牙设备执行上述步骤S3向第二目标设备发送主设备寻呼响应，那么主蓝牙设备执行的步骤相对较少，由副蓝牙设备尽可能多地分担步骤，从而充分利用副蓝牙设备的处理资源，尽可能地减少主蓝牙设备的处理量；如果由主蓝牙设备执行上述步骤S3向第二目标设备发送主设备寻呼响应，那么上文介绍的主蓝牙设备的相关信息可以不必提供给副蓝牙设备，有助于降低主副蓝牙设备之间的信令开销。
图6示出了本申请另一个实施例提供的建立蓝牙链路的方法的流程图。
在本实施例中，主蓝牙设备为主蓝牙耳机，副蓝牙设备为副蓝牙耳机。以方法应用于图4所示的方案实施环境中进行举例说明。其中，预置条件包括：手机#A和耳机已经配对，手机#A蓝牙打开或者关闭；手机#B和耳机已经配对，且手机#B蓝牙打开或者关闭；左耳机和右耳机均在耳机盒内；耳机盒关盒；左耳机和右耳机之间没有蓝牙连接；左耳机/右耳机和手机(包括手机#A和手机#B)之间没有蓝牙连接。用户使用场景为：耳机盒开盒，耳机自动回连手机#A和手机#B。
为了方便流程分析，将每个耳机分成两个部分：主程序(Host)和控制器(Controller)；其中，主程序是上层的软件，控制器是底层的硬件模块，负责处理蓝牙技术无线信号的发送和接收。
如图6所示，该方法可以包括以下几个步骤(601～614)：
步骤601，用户打开耳机盒，耳机盒向左耳机和右耳机分别发送开盒事件。
可选地，耳机盒向左耳机的主程序和右耳机的主程序，分别发送开盒事件。
步骤602，左耳机和右耳机之间建立连接，执行角色仲裁和合并PDL(Paired  Device List，配对设备列表)。
角色仲裁的目的是确定两个耳机之间的角色。可选地，角色仲裁的结果假设为左耳机担任主要角色(即左耳机为主蓝牙设备)，右耳机担任次要角色(即右耳机为副蓝牙设备)。
以TWS耳机为例，角色仲裁的过程可以如下：左耳机将自己的状态信息发给右耳机，状态信息包括：(a)是否在耳机的充电盒内，(b)是否连接了手机，(c)是否正在进行通话业务，(d)是否正在进行音乐业务等。右耳机将结合自己的状态信息和左耳机的状态信息，确定自己的角色。右耳机将自己的角色信息回复给左耳机。需要说明的是，对于不同的蓝牙设备，角色仲裁的过程可能会有所不同，本申请对此不作限定。
合并PDL的目的是将两个耳机的PDL合并在一起。由于两个耳机可以单独使用，那么有可能两个耳机配对了不同的设备，比如左耳机配对了手机#A，并且保存了手机#A的地址和密钥，右耳机配对了手机#B，并保存了手机#B的地址和密钥。此过程完成之后，左耳机和右耳机将都保存手机#A的地址和密钥以及手机#B的地址和密钥。
以TWS耳机为例，合并PDL的过程可以如下：左耳机将自己的配对记录发给右耳机，右耳机合并PDL，并保存合并之后的PDL，右耳机将合并之后的PDL发给左耳机，左耳机保存合并之后的PDL。需要说明的是，对于不同的蓝牙设备，合并PDL的过程可能会有所不同，本申请对此不作限定。
如果合并之后的PDL中包含的配对设备的数量小于2(表示为PDL＜2)，则主耳机(如左耳机)最多仅需连接一个目标设备；如果合并之后的PDL中包含的配对设备的数量大于或等于2(表示为PDL≥2)，则主耳机(如左耳机)至少需要连接两个目标设备。
图6所示的是PDL≥2的流程，其中手机#A是主耳机(如左耳机)管理连接状态，并且由主耳机向手机#A发起寻呼，手机#B是主耳机(如左耳机)管理连接状态，但是以副耳机(如右耳机)为代理向手机#B发起寻呼。
手机#A的蓝牙链路建立过程包括步骤603～605。
步骤603，左耳机的主程序向左耳机的控制器发送连接创建命令。
例如，该连接创建命令可以是标准的HCI_Create_Connection command。
步骤604，左耳机的控制器与手机#A之间执行上述步骤S1～S6的过程，建立左耳机与手机#A之间的蓝牙链路。
步骤605，在蓝牙链路建立完成之后，左耳机的控制器向左耳机的主程序发送连接完成事件。
例如，该连接完成事件可以是标准的HCI_Connection_Complete event。
手机#B的蓝牙链路建立过程包括步骤606～614。
步骤606，左耳机的主程序向右耳机的主程序发送连接通知，该连接通知用于指示右耳机作为左耳机的代理，向手机#B发起寻呼。
步骤607，右耳机的主程序向右耳机的控制器发送连接创建命令。
可选地，该连接创建命令可以是标准的HCI_Create_Connection command或 者私有的Create_Connection command。
步骤608，右耳机的控制器向手机#B发起寻呼。
步骤609，若寻呼手机#B成功，则右耳机的控制器向右耳机的主程序发送寻呼成功事件。
可选地，该寻呼成功事件可以是Page_Complete Event-Success或Vendor_Connection_Complete Event–Page Success。
步骤610，若寻呼手机#B失败，则右耳机的控制器向右耳机的主程序发送寻呼失败事件。
可选地，该寻呼失败事件可以是Page_Complete Event-Timeout或Vendor_Connection_Complete Event–Page Timeout。
步骤611，右耳机的主程序向左耳机的主程序发送连接结果。
可选地，在右耳机的主程序接收到寻呼成功事件的情况下，右耳机的主程序向左耳机的主程序发送连接成功结果(也可称为寻呼成功通知)，并携带连接信息，该连接信息包括时钟同步信息，该时钟同步信息用于使得左耳机与手机#B在相同的频点进行通信；在右耳机的主程序接收到寻呼失败事件的情况下，右耳机的主程序向左耳机的主程序发送连接失败结果(也可称为寻呼失败通知)。可选地，连接信息还可以包括地址信息、设备类型等信息，本申请实施例对此不作限定。
步骤612，右耳机的控制器向左耳机的控制器发送寻呼完成指示。
可选地，该寻呼完成指示可以是Page_Complete indication。
步骤613，左耳机的控制器与手机#B之间执行上述步骤5-6的过程，建立左耳机与手机#B之间的蓝牙链路。
例如，左耳机和右耳机之间交换特性信息，然后发送LMP建立完成消息。
步骤614，在蓝牙链路建立完成之后，左耳机的控制器向左耳机的主程序发送连接完成事件。
例如，该连接完成事件可以是Connection_Complete event。
需要说明的是，本实施例中涉及的一些消息或者事件的名称，仅是示例性和解释性的，该名称可以按照某种规范或需求进行设定，本申请对此不作限定。
另外，在本实施例中，仅以副耳机(即右耳机)执行上述步骤S3向手机#B发送主设备寻呼响应为例，即副耳机(即右耳机)执行步骤S1～S4且主耳机(即左耳机)接续执行步骤S5～S6，最终建立主耳机(即左耳机)与手机#B之间的蓝牙链路。在一些其他实施例中，也可以由主耳机(即左耳机)执行上述步骤S3向手机#B发送主设备寻呼响应，即副耳机(即右耳机)执行步骤S1～S2且主耳机(即左耳机)接续执行步骤S3～S6，最终建立主耳机(即左耳机)与手机#B之间的蓝牙链路。有关这两种方式的具体介绍说明，可参见上文实施例，此处不再赘述。
采用本申请提供的技术方案，通过自定义的私有指令(主耳机向副耳机发送的连接通知)，将连接的需求发给副耳机，实现两个目标设备(如两个手机)的并行连接，和相关技术的串行连接方案相比，能够获得5s～10s的正向收益， 提升用户体验。
需要说明的是，在上述方法实施例中，仅从主蓝牙设备和副蓝牙设备交互的角度，对本申请技术方案进行了介绍说明。上述有关主蓝牙设备执行的步骤，可以单独实现成为主蓝牙设备侧的蓝牙链路建立方法，上述有关副蓝牙设备执行的步骤，可以单独实现成为副蓝牙设备侧的蓝牙链路建立方法。
