具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
其中，在蓝牙协议栈中，服务发现协议(Service Discovery Protocol，SDP)也叫做蓝牙SDP，用于提供应用程序在蓝牙环境中特定的涵义，用于发现哪个服务可用和决定可用服务的特征。SDP定义了一个电子设备发现可用蓝牙服务器服务和特征的方法。其中，每一个SDP的PDU包括PDU头(Header)和PDU特定的参数(Parameter)；PDU头包括三个域：PDU标识符(PDU ID)、事务标识符(Transaction ID)和参数长度(Parameter Length)。
当前，电子设备之间可以通过蓝牙的方式进行连接。但是，某个电子设备在每次与另一电子设备进行蓝牙连接的过程中，都需要对每个指定连接(基于配置文件profile的连接)做SDP流程，来发现该另一电子设备针对该指定连接对应的配置文件的一些服务属性值，从而导致蓝牙连接的过程耗时较长。发明人经过研究发现，由于每次基于蓝牙链路的上层profile在建立蓝牙连接的时候都需要首先做SDP流程，然后再做profile层的连接，那么，如果某个电子设备和另一电子设备上运行多个profile时，则会执行多次的SDP流程，进而会加重蓝牙连接的耗时。
针对上述问题，发明人经过长期的研究发现，并提出了本申请实施例提供的设备连接方法、装置、电子设备以及存储介质，通过将指定配置文件的SDP数据做本地存储，简化后续基于指定配置文件的连接过程中的流程，提升蓝牙连接的速度。其中，具体的设备连接方法在后续的实施例中进行详细的说明。
下面将针对可用于本申请实施例提供的设备连接方法的应用环境进行描述。
如图1所示，第一电子设备100可以是用户终端(例如，可以是智能手机)，第二电子设备200可以是智能家居设备，该智能家居设备可以包括智能电视、空调、窗帘等电子设备，在第一电子设备100靠近第二电子设备200，且第一电子设备100和第二电子设备200在一定的距离范围内的时候，则第一电子设备100和第二电子设备200可以进行蓝牙连接。其中，若第一电子设备100和第二电子设备200在之前已经进行过蓝牙连接，则第一电子设备100和第二电子设备200可以进行回连。其中，回连是指，第一电子设备100发送page包至第二电子设备200，以请求建立与第二电子设备200间的通信连接，该page就是通常称为的连接(寻呼)，进行连接/激活第二电子设备200的操作就称为page，具体地，page是指发起连接的设备(第一电子设备)知道要连接设备(第二电子设备)的地址，则所以可以直接传呼。
如图2所示，第一电子设备100可以是用户终端(例如，可以是智能手机)，第二电子设备200可以是真无线蓝牙耳机(true wireless stereo，TWS)装置，在第二电子设备200靠近第一电子设备100，且第一电子设备100和第二电子设备200在一定的距离范围内的时候，则第一电子设备100和第二电子设备200可以进行蓝牙连接。在本申请一实施例中，该TWS蓝牙耳机装置可以包括耳机220和耳机盒(充电装置)210，耳机盒210可以容纳耳机220，在本申请一实施例中，耳机盒210的壳体内壁形成容纳腔，耳机220可以容纳在该耳机盒210的容纳腔内。另外，耳机盒210不仅可以提供用于容纳耳机220的容纳腔，还可以与耳机220通信，从而能获取耳机220的电量、名称或者耳机220的网络参数等信息，以便第一电子设备能通过耳机盒210与耳机220配对成功并实现通信连接。作为一种实施方式，该耳机盒210还用于为耳机220充电。在本申请一实施例中，在耳机盒210开盖时可以触发耳机220发射蓝牙低功耗(bluetooh low energy，BLE)广播，第一电子设备100，例如智能手机，在接收到该BLE广播后，可以基于该BLE广播与该耳机220建立蓝牙连接。
如图3所示，第一电子设备100可以是用户终端(例如，可以是智能手机)，第二电子设备200可以是真无线蓝牙耳机装置中的耳机。当用户终端100与耳机200连接时，则用户终端100与耳机200可以进行音频数据的传输。例如，用户终端100可以将通话对方的语音数据传输至耳机200，耳机200可以将通话己方的语音数据传输至用户终端100等，在此不做限定。
请参阅图4，图4示出了本申请一实施例提供的设备连接方法的流程示意图。该设备连接方法用于通过将指定配置文件的SDP数据做本地存储，简化后续基于指定配置文件的连接过程中的流程，提升蓝牙连接的速度。在具体的实施例中，该设备连接方法应用于如图11所示的设备连接装置300以及配置有设备连接装置300的电子设备(第一电子设备)100(图12)。下面将以电子设备为例，说明本实施例的具体流程，当然，可以理解的，本实施例所应用的电子设备可以包括智能手机、平板电脑、穿戴式电子设备、蓝牙耳机等具有蓝牙连接功能的设备。下面将针对图4所示的流程进行详细的阐述，所述设备连接方法具体可以包括以下步骤：
步骤S110：所述第一电子设备在向第二电子设备发起指定连接时，从所述第一电子设备的本地获取指定配置文件的SDP数据，其中，所述指定连接为基于所述指定配置文件的设备连接。
当两台电子设备建立蓝牙连接(如本实施例中的第一电子设备和第二电子设备在建立蓝牙连接)时，它们会获取对方设备提供的协议。只有使用相同协议的设备才能交换数据，就像两个人要使用相同的语言才能进行有意义的对话一样。其中，当蓝牙协议定义两台电子设备之间的物理无线连接时，蓝牙规格会建立进行蓝牙连接的电子设备能够使用蓝牙技术交换的命令和功能。
在一些实施方式中，第一电子设备和第二电子设备在进行蓝牙连接时，可以建立基于配置文件profile的连接。其中，profile可以包括(手机规格，Head-Set-Profile，HSP)、免提规格(Hands-Free-Profile，HFP)、高级音频传送规格(Advanced Audio Distribution Profile，A2DP)、音频/视频遥控规格，(Audio/Video Remote Control Profile，AVRCP)等，在此不做限定。其中，HSP和HFP蓝牙规格是典型单声道蓝牙电子设备操作所需的规格，A2DP和AVRCP对于立体声蓝牙电子 设备很重要。
其中，HSP是蓝牙连接中较为常用的配置，为当前流行支持如蓝牙耳机与智能手机使用，提供智能手机与蓝牙耳机之间通信所需的基本功能。连接和配置好后，蓝牙耳机可以作为远程设备的音频输入和输出接口。
其中，HFP在HSP的基础上增加了某些扩展功能，常用来让如车载免提装置来控制智能手机。它使用连续可变斜率增量调制或脉冲编码对数一法或μ-法量化音频通道调制。描述了网关设备如何用于供免提设备拨打和接听呼叫。典型配置如汽车使用智能手机作为网关设备。在车内，立体声系统用于电话音频，而车内安装的麦克风则用于通话时发送输出音频。HFP还可用于个人计算机在家中或办公环境中作为智能手机扬声器的情况。
其中，A2DP允许传输立体声音频信号(相比用于HSP和HFP的单声道加密，质量更好)。A2DP能够让两个同样支持蓝牙音效传输的电子设备互相连接，都能输出如CD音质(16bits，44.1kHz)般的音乐。假如有一方不支持A2DP，这时音效就只能输出Handsfree Profile(8bits，8kHz)。
其中，AVRCP用于从第二电子设备(如立体声耳机)向第一电子设备(如装有MediaPlayer的电脑)发送命令(如前跳、暂停和播放)。AVRCP设计用于提供控制TV、Hi-Fi设备等的标准接口。此规格用于许可单个远程控制设备(或其它设备)控制所有用户可以接入的A/V设备。它可以与A2DP或VDP配合使用。
在本实施例中，第一电子设备可以向第二电子设备发起指定连接。其中，指定连接可以为基于指定配置文件的设备连接，其中，该指定配置文件可以为HSP、HFP、A2DP以及AVRCP中的一种或几种的组合。例如，指定连接可以为第一电子设备向第二电子设备发起基于HSP的设备连接；指定连接可以为第一电子设备向第二电子设备发起基于A2DP的设备连接等，在此不做限定。
其中，第一电子设备和第二电子设备在配对完成之后，且进行连接之前都要进行服务的搜索，其中，服务搜索走的流程是SDP，即，第一电子设备需要执行SDP流程获得第二电子设备在该连接的SDP数据。而在本实施例中，第一电子设备在向第二电子设备发起指定连接时，则可以从第一电子设备的本地获取该指定配置文件(后续称profile)的SDP数据，从而不再走SDP流程，提升SDP数据的获取速度。
作为一种方式，第一电子设备在此次向第二电子设备发起指定连接之前，已与第二电子设备之间进行过指定连接，并在之前进行指定连接时已获得过该指定profile的SDP数据，因此，第一电子设备可以将之前进行指定连接时获得的指定profile的SDP数据存在本地，以便在后续进行指定连接时，可以直接从本地获取该指定profile的SDP数据，从而可以有效地提升SDP数据的获取速度。
步骤S120：基于所述指定配置文件的SDP数据，与所述第二电子设备进行所述指定连接。
在一些实施方式中，第一电子设备在从本地获取该指定profile的SDP数据后，则可以基于该指定profile的SDP数据，与第二电子设备进行指定连接，从而可以提升指定连接的速度。
本申请一实施例提供的设备连接方法，第一电子设备在向第二电子设备发起指定连接时，从第一电子设备的本地获取指定配置文件的SDP数据，其中，指定连接为基于指定配置文件的连接，基于指定配置文件的SDP数据，与第二电子设备进行指定连接，从而通过将指定配置文件的SDP数据做本地存储，简化后续基于指定配置文件的连接过程中的流程，提升蓝牙连接的速度。
请参阅图5，图5示出了本申请一实施例提供的设备连接方法的流程示意图。该方法应用于上述电子设备，下面将针对图5所示的流程进行详细的阐述，所述设备连接方法具体可以包括以下步骤：
步骤S210：所述第一电子设备在向第二电子设备发起指定连接时，从所述第一电子设备的本地获取指定配置文件的SDP数据，其中，所述指定连接为基于所述指定配置文件的设备连接。
步骤S220：基于所述指定配置文件的SDP数据，与所述第二电子设备进行所述指定连接。
其中，步骤S210-步骤S220的具体描述请参阅步骤S110-步骤S120，在此不再赘述。
步骤S230：当所述第一电子设备的本地未存储所述指定配置文件的SDP数据时，基于所述指定配置文件向所述第二电子设备进行服务搜索。
在一些实施方式中，第一电子设备在向第二电子设备发起指定连接时，可以判断该第一电子设备的本地是否存储有指定profile的SDP数据。作为一种方式，第一电子设备可以预先设定profile的SDP数据对应的存储区域，因此，当第一电子设备在向第二电子设备发起指定连接时，可以判断该第一电子设备的存储区域中是否包括该指定profile的SDP数据，从而可以减少查询的数据量。
其中，当判断结果表征该第一电子设备的本地存储有指定profile的SDP数据时，则可以从本地获取该指定profile的SDP数据，并基于该指定profile的SDP数据，与第二电子设备进行指定连接。
其中，当判断结果表征该第一电子设备的本地未存储有指定profile的SDP数据时，则可以基于该指定profile向第二电子设备进行服务搜索，即，当判断结果表征该第一电子设备的本地未存储有指定profile 的SDP数据时，则可以基于该指定profile向第二电子设备做SDP服务发现流程。
步骤S240：当所述服务搜索完成时，从所述第二电子设备获取所述指定配置文件的SDP数据。
在一些实施方式中，当第一电子设备基于该指定profile向第二电子设备进行服务搜索完成时，即第一电子设备基于该指定profile向第二电子设备做完SDP服务发现流程时，则可以从第二电子设备获取指定profile的SDP数据。
步骤S250：基于所述指定配置文件的SDP数据，与所述第二电子设备进行所述指定连接。
在一些实施方式中，第一电子设备在从第二电子设备获取该指定profile的SDP数据后，则可以基于该指定profile的SDP数据，与第二电子设备进行指定连接，以保证指定连接的成功率。

例如，当该指定profile的SDP数据中的所有SDP数据均为关键数据时，则可以直接提取该指定profile的SDP数据中的所有数据。又例如，当该指定profile的SDP数据中的部分SDP数据为关键数据时，则可以提取该指定profile的SDP数据中的部分数据(关键数据)。
步骤S470：将所述关键数据存储在所述第一电子设备的本地。
在一些实施方式中，在从指定profile的SDP数据中提取到关键数据后，可以将关键数据存储在第一电子设备的本地，而指定profile的SDP数据中的非关键数据则可以不存储。基于此，不仅可以保证后续蓝牙连接的速度和成功率。还可以降低存储量压力。

步骤S570：当所述变化情况表征所述指定配置文件的SDP数据为固定数据时，将所述指定配置文件的SDP数据存储在所述第一电子设备的本地。
在本实施例中，当确定该指定profile的SDP数据的变化情况表征该指定profile的SDP数据为固定数据时，则可以确定第一电子设备与第二电子设备在后续进行指定连接的过程中，该指定profile的SDP数据不会发生变化，即，第一电子设备在后续与第二电子设备进行指定连接时，也可以基于该指定profile的SDP数据。因此，可以将指定profile的SDP数据存储在第一电子设备的本地，以便在后续进行指定连接时，可以直接从本地获取该指定profile的SDP数据，从而可以有效地提升后续SDP数据的获取速度。
步骤S580：当所述变化情况表征所述指定配置文件的SDP数据为动态变化数据时，不将所述指定配置文件的SDP数据存储在所述第一电子设备的本地。
