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。
图1是本申请一些实施例提供的一种蓝牙连接方法所涉及的实施环境的示意图。如图1所示，该实施环境可以包括：显示终端110、发送端120、蓝牙设备130和无线接入设备140。该显示终端110可以是电视机、个人电脑、笔记本电脑、平板电脑或手机等具备显示功能的设备，该显示终端110中安装的操作系统可以为安卓操作系统。该发送端120可以为手机、个人电脑、笔记本电脑或平板电脑等设备。该蓝牙设备130可以为音箱、个人电脑、笔记本电脑、平板电脑或手机等具备蓝牙功能的设备。在一些实施例中，该蓝牙设备130可以支持蓝牙音频传输模型协定(advenced audio distribution profile，A2DP)。该无线接入设备140可以为无线路由器或有线路由器。该显示终端110与该发送端120之间可以通过无线接入设备140建立连接。该显示终端110与该蓝牙设备130之间可以通过蓝牙建立连接。
假设该显示终端110为电视机，该蓝牙设备130为音箱，在相关技术中，由于电视机中的蓝牙模块和WIFI模块同时接收供电电路的供电，则处于待机状态的电视机在通过WIFI模块接收到手机发送的唤醒指令后，可以开启蓝牙模块，并控制该蓝牙模块与蓝牙设备建立连接，该蓝牙设备与蓝牙模块建立连接后，会播放语音提示信息″连接成功″。之后，电视机可以对手机进行验证，若验证失败，则可以控制蓝牙模块与蓝牙设备断开连接，并关闭该蓝牙模块，该蓝牙设备与蓝牙模块断开连接后，会播放语音提示信息″连接失败″。由于处于待机状态的电视机在唤醒过程中，在手机验证失败的情况下，电视机会在与蓝牙设备建立连接后，再次断开与蓝牙设备的连接，导致电视机的功耗较大。且采用该方法使得电视机在待机状态下时，会出现蓝牙设备不断地发出语音提示的情况，使得用户体验较差。
图2是本申请一些实施例提供的一种蓝牙连接方法的流程图，该蓝牙连接方法可以应用于图1所示的显示终端110中。如图2所示，该方法可以包括：
步骤201、响应于与目标蓝牙设备建立蓝牙连接的连接指令，确定显示终端的屏幕状态。
其中，该屏幕状态可以包括亮屏状态或黑屏状态。若显示终端处于开机状态下，其屏幕状态为亮屏状态。若显示终端处于待机状态下，其屏幕状态为黑屏状态。
在一些实施例中，该连接指令可以是目标蓝牙设备发送至显示终端的，也可以是显示终端通过蓝牙模块生成的指令。并且，该目标蓝牙设备可以为一个蓝牙设备，也可以为多个蓝牙设备。
步骤202、检测显示终端的屏幕状态是否为亮屏状态。
显示终端在确定屏幕状态之后，可以检测其屏幕状态是否为亮屏状态，若显示终端的屏幕状态为亮屏状态，则可以执行步骤203。若显示终端的屏幕状态为黑屏状态，则可以执行步骤204。
步骤203、与目标蓝牙设备建立蓝牙连接。
显示终端在检测到屏幕状态为亮屏状态后，可以确定显示终端处于开机状态，因此可以通过蓝牙模块与目标蓝牙设备建立蓝牙连接。
步骤204、禁止与目标蓝牙设备建立蓝牙连接。
显示终端在检测到屏幕状态为黑屏状态后，可以确定显示终端处于待机状态，因此可以禁止蓝牙模块与目标蓝牙设备建立蓝牙连接。
综上所述，本申请一些实施例提供了一种蓝牙连接方法，该蓝牙连接方法可以响应于与目标蓝牙设备建立蓝牙连接的连接指令，确定显示终端的屏幕状态，若该屏幕状态为亮屏状态，则与目标蓝牙设备建立连接。若该屏幕状态为黑屏状态，则禁止与目标蓝牙设备建立连接。由于只有在显示终端的屏幕状态为亮屏状态时，显示终端才会与蓝牙设备建立连接，因而避免了显示终端在黑屏状态下与蓝牙设备建立连接的情况，同时避免了显示终端先与蓝牙设备建立连接后，若对发送端验证失败，则需要再次断开与蓝牙设备的连接的情况，相较于相关技术，降低了显示终端的功耗。
图3是本申请一些实施例提供的另一种蓝牙连接方法的流程图，在该方法的执行过程中，只要不产生处理上的冲突，部分步骤的顺序可以不分先后。该蓝牙连接方法可以应用于图1所示的显示终端110中，该方法可以包括：
步骤301、响应于待机指令，检测是否开启远程唤醒功能。
在本申请一些实施例中，如图4所示，显示终端110中可以包括同时接收供电电路的供电的蓝牙模块111和WIFI模块112，即该蓝牙模块111和WIFI模块112可以集成在一个芯片上。显示终端在开机状态下时，该WIFI模块和蓝牙模块均处于启动状态。
在一些实施例中，同时供电给蓝牙模块111和WIFI模块112是指，在供电电路供电的时候，蓝牙模块111和WIFI模块112均接收到供电，在供电电路切断供电的时候，蓝牙模块111和WIFI模块112均没有电力供应。
在一些实施例中，供电电路可以是显示终端总体电路中的一部分。
在一些实施例中，显示终端可以设置有待机按钮，显示终端在检测到针对待机按钮的点击操作后，可以生成待机指令，并可以响应于该待机指令，进入待机状态，同时检测显示终端是否开启远程唤醒功能，若显示终端确定未开启远程唤醒功能，则可以执行步骤302。若显示终端确定开启远程唤醒功能，则可以执行步骤303。
在本申请一些实施例中，显示终端的显示界面设置有远程唤醒按钮，响应于用户的输入，在检测到针对该远程唤醒按钮的点击操作后，显示终端可以开启远程唤醒功能。为了使得发送端可以远程唤醒处于待机状态的显示终端，用户需要在显示终端进入待机状态之前，开启该远程唤醒功能。
步骤302、关闭WIFI模块。
在一些实施例中，若显示终端确定未开启远程唤醒功能，则可以关闭WIFI模块，以使显示终端进入待机状态后，WIFI处于关闭状态。
此时，供电电路停止供电。WIFI模块也不会响应发送端的唤醒指令。需要用户通过物理键启动显示终端的供电后，供电电路启动蓝牙模块111和WIFI模块112的供电，然后蓝牙模块111和WIFI模块112才启动进入工作状态以进行蓝牙或WIFI的通讯过程。
步骤303、保持WIFI模块处于启动状态。
在一些实施例中，显示终端在确定开启远程唤醒功能后，可以保持WIFI模块处于启动状态，以使得发送端可以远程唤醒处于待机状态下的显示终端。此时，需要维持WIFI模块的供电，由于WIFI模块和蓝牙模块同时接收供电电路供电，因此显示终端在进入待机状态后，可以控制蓝牙模块处于上电但未启动状态。
在一些实施例中，蓝牙模块也可以维持开启状态。
在一些实施例中，显示终端还可以包括电源管理(power manage，PM)模块和随机存储器(random access memory，RAM)。在待机状态下，除了RAM、PM模块和WIFI模块，显示终端中的各个中央处理器(central processing unit，CPU)均会进入挂起(suspend)状态，即未工作状态。显示终端在进入待机状态之前运行的各个应用程序以及显示终端中的各个模块也均处于未工作状态，且显示终端的操作系统在进入待机状态之前的运行数据会保存在RAM中。
在本申请一些实施例中，显示终端在进入待机状态后，发送端在与显示终端处于同一局域网后自动发送该唤醒指令至显示终端。例如，发送端在与显示终端处于同一局域网后，可以周期性的向显示终端发送唤醒指令。
WIFI模块的至少部分功能一直处于启动状态，WIFI模块接收到发送端发送的唤醒指令后，可以调整其GPIO端口的电平。PM模块(显示终端的供电管理模块)在检测WIFI模块的GPIO端口的电平发生变化后，可以唤醒各个CPU，启动蓝牙模块，恢复启动内核空间和用户空间，并从RAM中快速的恢复(resume)操作系统的运行数据，以使的用户在接收到后续的亮屏指令后达到快速开机的效果。且在显示终端进入待机状态之前运行的所有应用程序以及各个处于未工作状态的模块均会重新启动。在一些实施例中，该显示终端处于开机状态时，其操作系统在内核空间中运行，各个应用程序在用户空间中运行。
但由于该唤醒指令中未携带亮屏指示信息，因此显示终端在接收到唤醒指令后，可以响应于该唤醒指令启动蓝牙模块，但并不会调整其屏幕状态，即显示终端的屏幕状态仍为黑屏状态。
在一些场景中，作为发送端的手机和电视机处于同一局域网后，即发送唤醒指令给电视机，例如携带手机的用户回家后，手机连上局域网后即发送唤醒指令给电视机，以使电视机处于热备状态，随时响应用户的开机需求。从而在手机发出亮屏指令后，电视可以快速点亮并进入可使用状态。
步骤304、在屏幕状态为黑屏状态时，通过WIFI模块接收亮屏指令。
在屏幕状态为黑屏状态时，显示终端可以通过WIFI模块接收发送端发送的亮屏指令，该亮屏指令可以为封装有发送端的设备信息以及亮屏指示信息的组播域名系统(muIticast domain name system，mDNS)报文。显示终端通过WIFI模块接收到该mDNS报文后，可以将该mDNS报文转发至组播域名系统守护进程(multicast domain name system daemon，mDNSD)，以通过mDNSD对该mDNS报文进行解析，进而得到发送端的设备信息和亮屏指示信息。
由于显示终端在待机状态下时，WIFI模块处于启动状态，因此显示终端可以通过该WIFI模块接收到发送端发送的亮屏指令。
在本申请一些实施例中，该亮屏指令是可以是发送端(例如，移动终端)响应于用户的触发操作生成的指令。在一些实施例中，发送端的显示界面可以设置有唤醒按钮，发送端可以在检测到针对该唤醒按钮的点击操作时，生成携带有设备信息和亮屏指示信息的亮屏指令。之后，发送端可以通过无线接入设备将该亮屏指令发送至显示终端。显示终端在处于待机状 态下时，可以通过处于启动状态的WIFI模块接收无线接入设备发送的亮屏指令。示例的，该发送端可以为手机，该唤醒按钮可以为手机中安装的视频应用程序中的投屏按钮。
步骤305、检测是否开启蓝牙模块。
处理器在通过WIFI模块接收到亮屏指令后，可以检测是否开启蓝牙模块，若显示终端确定未开启蓝牙模块，则显示终端可以执行步骤306。若确定已启动蓝牙模块，则可以执行步骤307。
在本申请一些实施例中，显示终端在进入待机状态后，且在通过WIFI模块接收亮屏指令之前，若显示终端通过WIFI模块接收到唤醒指令，则处理器可以响应于该唤醒指令，启动蓝牙进程，进而启动蓝牙模块。因此，显示终端在检测是否开启蓝牙模块时，若确定蓝牙模块处于启动状态，则处理器可以直接执行步骤307。
其中，该唤醒指令可以为封装有发送端的设备信息的mDNS报文，且该唤醒指令是发送端在与显示终端处于同一局域网后自动发送至显示终端的指令。例如，发送端在与显示终端处于同一局域网后，可以周期性的向显示终端发送唤醒指令。
需要说明的是，处理器通过WIFI模块接收到发送端发送的唤醒指令后，可以调整WIFI模块的通用输入/输出(general purpose input/output，GPIO)端口的电平。PM模块在检测WIFI模块的GPIO端口的电平发生变化后，可以唤醒各个CPU，启动蓝牙模块，恢复启动内核空间和用户空间，并从RAM中快速的恢复(resume)操作系统的运行数据，达到快速开机的效果。且在显示终端进入待机状态之前运行的所有应用程序以及各个处于未工作状态的模块均会重新启动。显示终端在启动蓝牙模块的过程中，会重新初始化蓝牙模块中的蓝牙协议栈以及所有上层的profile(蓝牙模块中数据通信的无线接口规范)。需要说明的是，该显示终端处于开机状态时，其操作系统在内核空间中运行，各个应用程序在用户空间中运行。
但由于该唤醒指令中未携带亮屏指示信息，因此处理器在接收到唤醒指令后，可以响应于该唤醒指令启动蓝牙模块，但并不会调整其屏幕状态，即显示终端的屏幕状态仍为黑屏状态。
需要说明的是，上述步骤304中的亮屏指令可以是处理器在接收到唤醒指令之前其处于待机状态下时接收到的指令，也可以是处理器响应于唤醒指令启动蓝牙模块之前或后接收到的指令。
步骤306、启动蓝牙模块。
处理器在确定未开启蓝牙模块后，可以控制蓝牙模块开启，之后可以执行步骤307。
需要说明的是，步骤306中启动蓝牙模块的过程，可以参考上述步骤305中显示终端响应于唤醒指令开启蓝牙模块的过程，本申请一些实施例在此不再赘述。
步骤307、检测设备信息是否验证成功。
处理器在确定蓝牙模块开启之后，可以对亮屏指令中携带的设备信息进行验证，若该设备信息验证成功，显示终端可以执行步骤308。若该设备信息验证失败，可以执行步骤309。
在本申请一些实施例中，显示终端处于开机状态时，发送端可以通过简单服务发现协议(simple service discovery protocol，SSDP)发现显示终端，并通过无线接入设备向显示终端发送mDNS报文，该mDNS报文中携带有发送端的设备信息。显示终端在通过WIFI模块接收到mDNS报文后，可以与发送端建立连接，并存储该发送端的设备信息。因此，处理器在对发送端的设备信息进行验证的过程中，可以获取亮屏指令中携带的设备信息，若该设备信息与显示终端预先存储的设备信息匹配，则可以确定对发送端的设备信息验证成功。若设备信息与显示终端预先存储的设备信息不匹配，则可以确定对发送端的设备信息验证失败。
示例的，假设电视机中预先存储了三个设备信息，分别为01：10：20：07：00：0A、00：00：20：08：0C：5A和00：10：10：05：0B：0A。若电视机解析mDNS报文获取到的手机的设备信息为00：00：20：08：0C：5A，则由于电视机中预先存储的三个设备信息中的00：00：20：08：0C：5A与手机的设备信息匹配，则处理器可以确定对该设备信息验证成功，并执行步骤308。否则，执行309。
步骤308、将屏幕状态调整为亮屏状态。
若对设备信息验证成功，则可以确定该发送端具备对显示终端进行远程操控的权限，则处理器可以响应于该亮屏指令，控制屏幕状态由黑屏状态调整为亮屏状态。
步骤309、关闭蓝牙模块，并保持屏幕状态为黑屏状态。
若对设备信息验证失败，则显示终端可以确定在进入待机状态之前，该发送端并未与显示终端建立过连接，因此该发送端不具备对显示终端远程操控的权限，则处理器可以控制蓝牙模块关闭，并保持屏幕状态为黑屏状态，即显示终端继续保持待机状态。
需要说明的是，显示终端在关闭蓝牙模块的同时，也需要关闭在步骤305或步骤306中启动的内核空间、用户空间、处于工作状态的应用程序以及显示终端中处于工作状态的各个模块，并将操作系统在进入待机状态之前的运行数据再次存储至RAM中，各个CPU再次进入suspend状态。直至再次接收到唤醒指令。
步骤310、基于设备信息的验证结果，设置显示终端的屏幕属性标识。
该屏幕属性标识可以用于指示显示终端的屏幕状态，该屏幕状态可以为亮屏状态或者黑屏状态。示例的，该屏幕属性标识可以为sys.screen.state。
处理器在对设备信息验证之后，若设备信息验证成功，则可以将显示终端的屏幕属性标识设置为第一标识，该第一标识用于指示屏幕状态为亮屏状态。若设备信息验证失败，则可以将显示终端的屏幕属性标识设置为第二标识，该第二标识用于指示屏幕状态为黑屏状态。在一些实施例中，该第一标识可以为真(true)，该第二标识可以为假(false)。
示例的，假设设备信息验证成功，则电视机可以将其屏幕属性标识sys.screen.state设置为true。假设设备信息验证失败，则电视机可以将其屏幕属性标识sys.screen.state设置为false。
步骤311、响应于与目标蓝牙设备建立蓝牙连接的连接指令，根据屏幕属性标识，确定显示终端的屏幕状态。
在一些实施例中，该连接指令可以是由目标蓝牙设备发送至显示终端的指令，也可以是由显示终端通过蓝牙模块生成的指令。该目标蓝牙设备可以为一个蓝牙设备，也可以为多个蓝牙设备。
作为一种在一些实施例中实现方式，处理器可以接收目标蓝牙设备发送的连接指令。
随着蓝牙设备的升级，蓝牙设备中可以存储显示终端的设备信息，因此目标蓝牙设备可以在显示终端进入开机状态后，主动向显示终端发送连接指令。相应的，处理器可以通过蓝牙模块接收到该目标蓝牙设备发送的连接指令。
作为另一种在一些实施例中实现方式，处理器可以确定在待机状态之前通过蓝牙模块建立蓝牙连接的目标蓝牙设备，并生成与目标蓝牙设备建立蓝牙连接的连接指令。
在一些实施例中，处理器可以将进入待机状态之前最后连接的一个蓝牙设备确定为目标蓝牙设备，或者处理器也可以将进入待机状态之前的指定时间段内所连接的多个蓝牙设备均确定为目标蓝牙设备。
示例的，显示终端在开启蓝牙模块之后，可以控制蓝牙模块加载配置文件，该配置文件中存储有在显示终端进入待机状态之前与该显示终端建立蓝牙连接的蓝牙设备的设备信息。显示终端可以将该配置文件中设备信息保存完整的蓝牙设备确定为目标蓝牙设备，并基于该目标蓝牙设备的设备信息，生成与目标蓝牙设备建立蓝牙连接的连接指令。例如，该配置文件可以为后缀名为.conf的文件，例如可以为bt_config.conf。
在本申请一些实施例中，处理器在获取与目标蓝牙设备建立蓝牙连接的连接指令后，可以响应于该连接指令，获取屏幕属性标识，并根据获取到的屏幕属性标识，确定显示终端的 屏幕状态。
例如，若该屏幕属性标识为第一标识，则处理器可以确定显示终端的屏幕状态为亮屏状态。若该屏幕属性标识为第二标识，则处理器可以确定显示终端的屏幕状态为黑屏状态。
步骤312、若屏幕状态为亮屏状态，与目标蓝牙设备建立蓝牙连接。
处理器在确定屏幕状态为亮屏状态后，可以确定显示终端处于开机状态，因此可以通过蓝牙模块与目标蓝牙设备建立蓝牙连接。
在一些实施例中，若连接指令为目标蓝牙设备发送至显示终端的指令，则显示终端中的蓝牙模块在接收到目标蓝牙设备发送的连接指令后，可以将该连接指令上报至蓝牙协议栈，该蓝牙协议栈可以通过调用第一连接接口与目标蓝牙设备建立连接。其中，该第一连接接口的名称可以为sink_connect_src。
若该连接指令是由显示终端通过蓝牙模块生成的指令，则显示终端在生成连接指令后，可以通过上层A2DP profile将该连接指令转发至蓝牙协议栈，以使得蓝牙协议栈调用第二连接接口与目标蓝牙设备建立蓝牙连接。其中，该第二连接接口的名称可以为src_connect_sink。
需要说明的是，若目标蓝牙设备具备语音播放功能，则显示终端在与目标蓝牙设备建立蓝牙连接后，该目标蓝牙设备还可以播放语音提示消息″连接成功″。由于显示终端只有在处于亮屏状态后才会与蓝牙设备建立蓝牙连接，该蓝牙连接方法可以避免显示终端在待机状态下蓝牙设备不断播放语音提示消息的情况，提高了用户体验。
步骤313、若屏幕状态为黑屏状态，禁止与目标蓝牙设备建立蓝牙连接。
处理器在确定屏幕状态为黑屏状态后，可以确定显示终端处于待机状态，因此可以禁止与目标蓝牙设备建立蓝牙连接。
在本申请一些实施例中，参考图4和图5，该显示终端110还可以包括主控制芯片113、屏幕背光模块114、电源管理单元(power manage unit，PMU)115和晶体振荡器(external oscillator，XO)116。该主控制芯片113分别与蓝牙模块111、WIFIF模块112和屏幕背光模块114连接。其中，该主控制芯片113可以通过通用串行总线(universal serial bus，USB)接口117与蓝牙模块111和WIFI模块112连接。

需要说明的是，本申请一些实施例提供的蓝牙连接方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行删除。例如，步骤301至步骤310可以根据情况进行删除。任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本公开的保护范围之内，因此不再赘述。
