Description

一种蓝牙服务的查询方法及电子设备 技术领域
本申请涉及通信技术领域，尤其涉及一种蓝牙服务的查询方法及电子设备。
背景技术
目前，通过通用唯一识别码(universally unique identifier，UUID)来标识蓝牙服务。其中，不同的UUID标识的蓝牙服务不同。手机、平板电脑等电子设备使用对端蓝牙设备提供的蓝牙服务之前，需要查询对端蓝牙设备的蓝牙服务UUID列表(service UUID list)，来确定对端蓝牙设备支持哪些蓝牙服务。具体的，对端蓝牙设备的service UUID list中包括至少一个UUID，至少一个UUID中的每个UUID用于标识一个对端蓝牙设备所支持的蓝牙服务。
以蓝牙耳机为例，例如，蓝牙耳机的service UUID list包括UUID1和UUID2。其中，UUID1用于标识蓝牙音频传输模型协定(advanced audio distribution profile，A2DP)，UUID2用于标识免提协定(hands-free profile，HFP)。A2DP指的是蓝牙耳机与手机通过蓝牙连接后，可以作为手机的麦克风和听筒，进行语音通话，也可以作为手机的播放设备，播放手机上的音频文件。HFP指的是蓝牙耳机与手机通过蓝牙连接后，可以控制接听、拒接或挂断手机上的来电、或者，控制使用手机拨打电话等。
实际应用中，手机是通过应用程序(例如系统应用、第三方应用等)来查询对端蓝牙设备的service UUID list的。具体的，如图1所示，应用程序向手机中的蓝牙芯片发送查询对端蓝牙设备的蓝牙服务的请求，手机中的蓝牙芯片接收到查询对端蓝牙设备的蓝牙服务的请求后，向对端蓝牙设备发送蓝牙服务的查询命令，对端蓝牙设备的蓝牙芯片在接收到查询命令后，获取service UUID list，并将获取到的service UUID list返回给手机中的蓝牙芯片，然后由手机中的蓝牙芯片将接收到的来自对端蓝牙设备的service UUID list返回给应用程序。通过上述蓝牙服务的查询方式，当手机上需要查询对端蓝牙设备的蓝牙服务的应用程序较多时，可能会使得对端蓝牙设备同时接收到来自多个应用程序的蓝牙服务的查询命令，导致超出自身蓝牙芯片的处理能力，从而导致手机与对端蓝牙设备的连接异常。另外，对于手机上安装的一些第三方应用，还可能会频繁地向对端蓝牙设备的蓝牙芯片发送蓝牙服务的查询命令，导致对端蓝牙设备出于自我保护，也可能会断开与手机之间的蓝牙连接。
综上所述，现有技术中这种直接向对端蓝牙设备下发查询命令，来查询蓝牙服务的方法，容易导致蓝牙连接出现异常，降低用户体验。

应理解，电子设备100当开启了蓝牙功能后，可以作为从设备(slave)被附近开启了蓝牙功能的电子设备扫描发现，也可以作为主设备(master)扫描发现附近开启了蓝牙功能的电子设备。示例的，如图5所示，若电子设备100和电子设备200均开启了蓝牙功能，且电子设备200位于电子设备100的附近，则电子设备100和电子设备200可以相互扫描发现，从而可以建立蓝牙连接。
下面以电子设备100为主设备，电子设备200为从设备为例，对电子设备100和电子设备200建立蓝牙连接的过程进行介绍。

在一些实施例中，电子设备100可以按照下列方式执行设备扫描过程：
方式一：电子设备100作为主设备在开启了蓝牙功能后，广播扫描请求，附近开启了蓝牙功能的电子设备(例如电子设备200)作为从设备可以在接收到扫描请求后，向电子设备100发送扫描响应，从而使得电子设备100发现附近开启了蓝牙功能的电子设备。
方式二：电子设备100作为主设备可以在开启了蓝牙功能后，接收附近开启了蓝牙功能的电子设备(从设备)的广播消息，而不会发送扫描请求。其中，附近开启了蓝牙功能的电子设备可以周期性广播消息，有助于其它开启了蓝牙功能的电子设备扫描发现。例如，电子设备100在开启了蓝牙功能后，接收到电子设备200的广播消息，从而扫描发现电子设 备200。
需要说明的是，电子设备100当扫描发现电子设备200后，则与电子设备200建立了物理链路。
本申请实施例中电子设备100在扫描发现电子设备200后，执行设备配对过程，与电子设备200进行配对。具体的，电子设备100可以在扫描发现电子设备200后，向电子设备200发送配对请求，电子设备200在接收到电子设备100的配对请求后，对电子设备100进行设备认证，并在设备认证通过后，向电子设备100发送配对成功响应，从而使得电子设备100建立与电子设备200之间的逻辑链路控制和适配协议(logical link control and adaptation protocol，L2CAP)信道。例如，电子设备100若未与电子设备200建立过蓝牙连接，则可以响应于用户在可用设备列表中选中电子设备200的标识，向电子设备200发送配对请求。再例如，电子设备100若与电子设备200建立过蓝牙连接，则可以当扫描发现电子设备200后，可以自动向电子设备200发送配对请求。除此之外，本申请实施例中还可以通过其它方式触发电子设备100向电子设备200发送配对请求，对此不作限定。
需要说明的是，本申请实施例中，电子设备100可以响应于触发向电子设备200发送配对请求的操作，停止设备扫描过程，也可以在电子设备100开启了蓝牙功能后，一直持续执行设备扫描过程，直至电子设备100关闭蓝牙功能后，不再执行设备扫描过程。
需要说明的是，本申请实施例中电子设备100与电子设备200配对完成后，还需要查询到电子设备200支持的蓝牙服务，才能够使得电子设备100与电子设备200之间完成蓝牙连接的建立。应理解，本申请实施例中不同类型的电子设备支持的蓝牙服务可以相同，也可以不同。例如，对于蓝牙耳机来说，支持的蓝牙服务可以包括A2DP、HFP和音频视频远距离控制协定(audio/video remote control profile，AVRCP)、耳机应用模型(head set profile，HSP)等。
在一些实施例中，电子设备100通过与电子设备200之间进行服务发现协议(service discovery protocol，SDP)交互操作，使得电子设备100可以通过自身的蓝牙芯片直接向电子设备200的蓝牙芯片发送蓝牙服务的查询命令，来获取电子设备200的service UUID list。这种通过芯片透传来查询蓝牙服务的方式，容易导致电子设备100和电子设备200之间的蓝牙连接出现异常，有鉴于此，本申请实施例提供了一种蓝牙服务的查询方法，可以通过在电子设备100中预先存储的电子设备支持的蓝牙服务的信息，使得电子设备100中安装的应用程序当请求查询某个电子设备支持的蓝牙服务时，可以从预先存储的电子设备100中的电子设备支持的蓝牙服务信息进行查询，从而有助于降低直接向对端电子设备查询蓝牙服务的次数，在一定程度上还有助于提高蓝牙服务查询的效率。

需要说明的是，本申请实施例中扫描结果可以为设备扫描过程中已有的消息，例如扫描响应、广播消息等。示例的，对于不同的电子设备，扫描结果的实现形式也可以不同。例如对于经典蓝牙(BR/EDR)设备来说，扫描结果可以为扩展需求结果(Extended Inquiry Result)，对于低功耗蓝牙(BLE)设备来说，扫描结果可以为广播包。此外，扫描结果还可以为新定义的消息。
以图2所示的电子设备100的结构为例。具体的，处理器110(例如应用处理器)检测到开启了蓝牙功能，则向无线通信模块132(例如蓝牙芯片)发送设备扫描命令，无线通信模块132接收到设备扫描命令后，接收来自附近的至少一个电子设备发送的扫描结果。例如，无线通信模块132接收到设备扫描命令后，还可以广播扫描请求。附近的至少一个电子设备中的部分电子设备可以响应于接收到扫描请求，向无线通信模块132发送扫描结果。附近的至少一个电子设备中部分电子设备还可以在开启了蓝牙功能后，可以无需接收扫描请求，直接广播扫描结果。在一些实施例中，附近的至少一个电子设备在开启了蓝牙功能后，可以周期性广播扫描结果。其中广播扫描结果的周期可以根据实际情况进行设定。从而有助于被其它开启了蓝牙功能的电子设备扫描发现。

以图2所示的电子设备100的结构、且电子设备100与电子设备200配对为例。具体的，处理器110响应于触发与电子设备200配对的操作，向无线通信模块132发送与电子设备200的配对通知，无线通信模块132接收到与电子设备200的配对通知后，向电子设 备200发送配对请求。电子设备200接收到配对请求后，对电子设备100进行认证，并在认证通过后，向电子设备100发送配对成功响应。配对成功响应中包括电子设备200支持的至少一个蓝牙服务的信息。例如配对成功响应中包括电子设备200的标识、和至少一个UUID。每个UUID用于标识一个电子设备200支持的蓝牙服务。无线通信模块132接收到配对成功响应后，从配对成功响应中获取电子设备200支持的至少一个蓝牙服务的信息，并以相应的存储形式存储到相应的存储器中。例如，电子设备100可以将从配对成功响应中获取电子设备200支持的至少一个蓝牙服务的信息以配置文件(例如bt_config.conf)的形式存储到内部存储器121、与外部存储器接口122连接的外部存储器、处理器110或者无线通信模块132中设置的存储器中的一个或多个存储器中。
应理解，当电子设备100与电子设备200首次配对成功后，则电子设备100中存储有电子设备200支持的蓝牙服务的信息，当电子设备200再次与电子设备100配对时，可以在接收到电子设备200发送的配对成功响应后，不再从配对成功响应中获取电子设备200支持的蓝牙服务的信息，也可以继续从配对成功响应中获取电子设备200支持的蓝牙服务的信息，并可以根据获取的电子设备200支持的蓝牙服务的信息更新已存储的电子设备200支持的蓝牙服务的信息。
例如，电子设备100与电子设备200首次配对成功后，存储的电子设备200支持的蓝牙服务的信息如表4所示。其中，设备标识b为电子设备200的标识，UUID1、UUID2和UUID3分别用于指示电子设备200支持的一种蓝牙服务。

需要说明的是，图6所示的预先存储电子设备的蓝牙服务的信息的方法仅为一个示例，本申请实施例中电子设备100还可以只保存扫描结果中包括的电子设备支持的蓝牙服务的信息，而不保存配对成功响应中包括的电子设备支持的蓝牙服务的信息；或者，电子设备100还可以不保存扫描结果中包括的电子设备支持的蓝牙服务的信息，只保存配对成功响应中包括的电子设备支持的蓝牙服务的信息。
此外，在本申请实施例中，电子设备100当既保存扫描结果中包括的电子设备支持的蓝牙服务的信息，又保存配对成功响应中包括的电子设备支持的蓝牙服务的信息时，可以将扫描结果中包括电子设备支持的蓝牙服务信息和配对成功响应中包括的电子设备支持的蓝牙服务的信息保存在一起。应理解，当扫描结果中包括电子设备支持的蓝牙服务信息和配对成功响应中包括的电子设备支持的蓝牙服务的信息保存在一起时，则扫描结果中包括的电子设备支持的蓝牙服务信息和配对成功响应中包括的电子设备支持的蓝牙服务的信息存储位置和存储形式相同。
以电子设备200为例，电子设备100接收到电子设备200发送的扫描结果，扫描结果中包括设备标识b、UUID1和UUID2。电子设备100根据扫描结果，保存电子设备200支持的蓝牙服务的信息如表6所示。

例如，电子设备100接收到电子设备200的配对成功响应，配对成功响应中包括设备标识b、UUID1、UUID2、UUID3和UUID4，则电子设备100根据电子设备200的配对成功响应更新表6所示的电子设备200支持的蓝牙服务的信息，更新后的电子设备200支持的蓝牙服务的信息如表7所示。
表7

示例的，表8所示的电子设备200支持的蓝牙服务的信息可以以第一存储形式存储在存储器1中，表9所示的电子设备200支持的蓝牙服务的信息可以以第二存储形式存储在存储器2中。其中，第一存储形式和第二存储形式可以不同，例如第一存储形式可以为数据库，第二存储形式可以为配置文件，第一存储形式和第二存储形式也可以相同。存储器1和存储器2可以相同，也可以不同。
在另外一些实施例中，电子设备100中预先存储的电子设备支持的蓝牙服务的信息还可以为电子设备100出厂之前存储的。例如，电子设备100中预先存储的电子设备设备支持的蓝牙服务的信息可以包括设备类型、以及与设备类型对应的至少一个UUID。示例的，电子设备100中预先存储的电子设备支持的蓝牙服务的信息可以如表10所示。
表10
Figure PCTCN2018123556-appb-000011
基于上述电子设备100存储电子设备支持的蓝牙服务的方法，本申请实施例提供了一种蓝牙服务的查询方法。示例的，如图7所示，为本申请实施例提供的一种蓝牙服务的查询方法的流程示意图。包括以下步骤。
步骤701，电子设备100检测到第一应用程序请求获取电子设备200的蓝牙服务。
步骤702，电子设备100根据电子设备200的标识，从预先存储的电子设备支持的蓝牙服务的信息中，查询电子设备200支持的蓝牙服务。
需要说明的是，在一些实施例中，第一应用程序可以为系统应用(例如系统设置等)，可以为第三方应用(例如微信、优酷视频等)，对此不作限定。在另一些实施例中，第一应用程序为第三方应用。电子设备100当系统应用请求获取电子设备200的蓝牙服务时，可以采用现有技术中蓝牙服务的查询方式来获取。
以图2所示的电子设备100的结构为例。具体的，处理器110(例如应用处理器)检测到第一应用程序请求获取电子设备200的蓝牙服务时，可以调用第一应用程序的接口， 向无线通信模块132(例如蓝牙芯片)发送获取电子设备200的蓝牙服务的请求。无线通信模块132通过第一应用程序的接口接收到处理器110发送的获取电子设备200的蓝牙服务的请求，则根据电子设备200的标识，从预先存储在相应存储器的电子设备支持的蓝牙服务的信息中，获取电子设备200的蓝牙服务，并将获取的电子设备200的蓝牙服务通过第一应用程序的接口返回给处理器110。
然而，由于第一应用程序请求查询电子设备200的蓝牙服务时，电子设备200与电子设备100所处于配对状态可能是已配对，也可能是正在配对，还有可能是未配对，因此，在一些具体的实施例中，电子设备100可以在检测到第一应用程序请求获取电子设备200的蓝牙服务后，先检测电子设备200与电子设备100所处的配对状态。当电子设备200与电子设备100处于已配对状态时，再执行步骤702，当电子设备200与电子设备100处于正在配对状态时，可以等待电子设备200与电子设备100配对成功后，在执行步骤702。当电子设备200与电子设备100处于未配对状态时，可以不再执行查询电子设备200支持的蓝牙服务的步骤，从而有助于减少电子设备100的信令处理。
示例的，无线通信模块132通过第一应用程序的接口接收到处理器110发送的获取电子设备200的蓝牙服务的请求后，可以先检测电子设备100与电子设备200所处的配对状态，然后根据电子设备100与电子设备200所处的配对状态，判断是否执行查询电子设备200支持的蓝牙服务的步骤。
在另一些实施例中，电子设备100当从预先存储在相应存储器的电子设备支持的蓝牙服务的信息中未获取到电子设备200的蓝牙服务时，可以向电子设备200发送蓝牙服务的查询命令。从而有助于提高电子设备100获取电子设备200支持的蓝牙服务成功的可能性。需要说明的是，电子设备100向电子设备200发送的蓝牙服务的查询命令可以为SDP命令。
示例的，无线通信模块132当从预先存储在相应存储器的电子设备支持的蓝牙服务的信息中未获取到电子设备200的蓝牙服务时，可以直接向电子设备200发送蓝牙服务的查询命令，也可以通过第一应用程序的接口向处理器110发送查询失败的通知，由处理器110决定是否由无线通信模块132向电子设备200发送蓝牙服务的查询命令。具体的，本申请实施例对处理器110判断是否由无线通信模块132向电子设备200发送蓝牙查询命令的策略可以根据实际情况需要进行设定。
特别的，在电子设备100采用图6所示的方法来预先存储电子设备支持的蓝牙服务的信息，且扫描结果和配对成功响应中包括的电子设备支持的蓝牙服务的信息分开存储情况下，在具体实现时，电子设备100还可以通过其它方式查询电子设备200的蓝牙服务。
下面以步骤602中电子设备100将至少一个电子设备支持的蓝牙服务的信息存储为uuid.db、步骤605中电子设备100将电子设备支持的蓝牙服务的信息存储为bt_config.conf文件为例，对第一应用程序请求查询电子设备200的蓝牙服务进行详细说明。
在一些实施例中，电子设备100检测到第一应用程序请求获取电子设备200的蓝牙服务，根据电子设备200与电子设备100所处的配对状态，确定从uuid.d还是从bt_config.conf中查询电子设备200支持的蓝牙服务。
需要说明的是，第一应用程序可以为系统应用，也可以为第三方应用，对此不作限定。另外，在本申请实施例中，电子设备100还可以在检测到第一应用程序请求获取电子设备200的蓝牙服务时，若第一应用程序为第三方应用，则根据电子设备200与电子设备100 所处的配对状态，确定从uuid.d还是从bt_config.conf中查询电子设备200支持的蓝牙服务。在一些实施例中，电子设备100检测到第一应用程序请求获取电子设备200的蓝牙服务时，若第一应用程序为系统应用，则可以直接从bt_config.conf中查询电子设备200支持的蓝牙服务。
下面对电子设备100根据电子设备200与电子设备100所处的配对状态，确定从uuid.d还是从bt_config.conf中查询电子设备200支持的蓝牙服务进行详细说明。
例如，电子设备100当电子设备200与电子设备100处于已配对状态时，可以从uuid.db中查询电子设备200支持的蓝牙服务，以及从bt_config.conf中查询电子设备200支持的蓝牙服务，并对分别从uuid.db中查询到的电子设备200支持的蓝牙服务、和从bt_config.conf中查询电子设备200支持的蓝牙服务取并集，得到电子设备200支持的蓝牙服务。
以如图2所示的电子设备100的硬件结构为例。具体的，无线通信模块132当电子设备200与电子设备100处于已配对状态时，可以从uuid.db中查询电子设备200支持的蓝牙服务，以及从bt_config.conf中查询电子设备200支持的蓝牙服务，并对分别从uuid.db中查询到的电子设备200支持的蓝牙服务、和从bt_config.conf中查询电子设备200支持的蓝牙服务取并集，然后将取并集后的电子设备200支持的蓝牙服务返回给处理器110。示例的，无线通信模块132可以通过第一应用程序的接口，将取并集后的电子设备200支持的蓝牙服务返回给处理器110，也可以由无线通信模块132通过intent广播取并集后的电子设备200支持的蓝牙服务，处理器110调用第一应用程序的接口来监测到intent广播，来接收取并集后的电子设备200支持的蓝牙服务。
再例如，电子设备100当电子设备200与电子设备100处于未配对状态时，可以从uuid.db中查询电子设备200支持的蓝牙服务。
以如图2所示的电子设备100的硬件结构为例。具体的，无线通信模块132当电子设备200与电子设备100处于未配对状态时，可以从uuid.db中查询电子设备200支持的蓝牙服务，然后通过第一应用程序的接口将查询到的电子设备200支持的蓝牙服务返回给处理器110。在一些实施例中，无线通信模块132当电子设备200与电子设备100处于未配对状态时，从uuid.db中未查询到电子设备200支持的蓝牙服务，则通过第一应用程序的接口向处理器110返回查询失败的通知。
又例如，电子设备100当电子设备200与电子设备100处于正在配对状态时，可以从uuid.db中查询电子设备200支持的蓝牙服务。
以如图2所示的电子设备100的硬件结构为例。具体的，无线通信模块132当电子设备200与电子设备100处于正在配对状态时，可以从uuid.db中查询电子设备200支持的蓝牙服务，然后通过第一应用程序的接口将查询到的电子设备200支持的蓝牙服务返回给处理器110。在另一些实施例中，无线通信模块132当电子设备200与电子设备100处于正在配对状态时，从uuid.db中未查询到电子设备200支持的蓝牙服务，则通过第一应用程序的接口向处理器110返回电子设备200与电子设备100处于正在配对的状态。处理器110通过第一应用程序的接口接收到电子设备200与电子设备100处于正在配对的状态后，确定当前为busy模式，可以等电子设备200与电子设备100配对成功后，再通过第一应用程序的接口向无线通信模块132发送获取电子设备200的蓝牙服务的请求。此外，处理器110通过第一应用程序的接口接收到电子设备200与电子设备100处于正在配对的状态后，确定当前为busy模式，可以通过第一应用程序的接口向无线通信模块132发送等待电子设 备200与电子设备100配对成功再查询电子设备200的蓝牙服务的通知。
