具体实施方式
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，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书的术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤的过程或结构的装置不必限于清楚地列出的那些结构或步骤而是可包括没有清楚地列出的或对于这些过程或装置固有的其它步骤或结构。
在相关的WIFI直连协议中，在设备发现和服务发现两个阶段，两方设备都必须在监听和搜索状态中进行时间上(100毫秒到300毫秒)和频率上(1,6,11三个信道)的随机切换，随机切换的目的是为了不让一方设备在监听的时候，另一方设备一直无法切换到正确的频率上进行搜索找到对方设备。然而这种随机切换方式，在一定的概率之下会造成设备发现和服务发现阶段花费时间过长，从而造成时间的浪费，甚至因为直连超时导致直连失败的问题。
本申请实施例提供一种无线连接方法。由于本申请实施例通过蓝牙广播消息来实现WIFI直连过程中的设备发现和服务发现，因此，不需要第一设备和第二设备在时间上和信道上通过随机切换的方式来搜索和监听对方，从而缩短了WIFI直连所需的时间，提高 了直连效率，降低了由直连超时导致的直连失败的概率。如图1所示，为本申请实施例提供的一种无线连接方法的流程图，该方法包括如下步骤：
步骤101、第二设备接收第一设备的第一蓝牙广播消息，所述第一蓝牙广播消息包括第一信道指针。
本实施例中涉及的第一设备和第二设备可以是诸如电视、手机、笔记本电脑、数码相机等内置有低功耗蓝牙组件，具备WIFI直连功能的终端设备。
在启动蓝牙功能并进入等待连接页面后，第二设备通过低功耗蓝牙组件发送第一蓝牙广播消息。第一广播消息中至少携带有用于指示第一设备在哪一个信道上接收第二蓝牙广播消息的第一信道指针，可选的，还可以携带第一标志位，该标志位用于表示第一设备是否是用于WIFI直连的设备。示例的，本实施例中第一蓝牙广播消息可以为ADV_EXT_IND帧的形式，在图2所示的ADV_EXT_IND帧中，设定标头中第二个Bit(在蓝牙规范中为RFU栏位)的值为预设数值时(本示例中为“1”，实际应用中还可以设置为其他数值)，第一设备为Miracast直连的设备，第十三字节(也是RFU栏位)设定为唯一特定的数值(例如图2中的00101110，但不局限于此数值，可根据需要进行设置)以识别这是第一设备发出的ADV_EXT_IND帧，其中第一信道指针可以携带在图2中“24个以上字节”的位置上或者“12字节”的位置上。当然此处仅为示例说明而不是对本申请的唯一限定。
步骤102、第二设备在第一信道指针指向的信道上接收所述第一设备的第二蓝牙广播消息，所述第二蓝牙广播消息包括所述第一设备的WIFI直连地址。
可选的，本实施例中第二广播消息的发送方式包括如下几种：
在一种实施方式中，第一设备在发送第一蓝牙广播消息之后间隔预设时间长度发送第二蓝牙广播消息，以确保第二设备有足够时间从第一蓝牙广播消息中解析出第一信道指针，并做好在第一信道指针所指向的信道上接收第二蓝牙广播消息的准备，提高传输第二蓝牙广播消息的成功率。
在另一种实施方式中，第一设备在发送第一蓝牙广播消息之后持续重复发送第二蓝牙广播消息，直到预设时间之后停止发送，从而确保第二设备能够成功接收到第二蓝牙广播消息。
在又一种实施方式中，第一设备交替发送第一蓝牙广播消息和第二蓝牙广播消息，以确保第二设备能够成功接收到第一蓝牙广播消息和第二蓝牙广播消息。
本实施例中，第二蓝牙广播消息必要的包括第一设备的WIFI的直连地址，可选的，还可以包括信道号和其它的服务设置信息(比如音频格式或视频格式等)。其中，该信道 号为第一设备在群组形成阶段拟定使用的信道号。示例的，本实施例中第二蓝牙广播消息可以为ADV_ADV_IND帧的形式，在图3所示的ADV_ADV_IND帧中，前六个字节为第一设备的WIFI直连地址，接下来一个字节是第一设备在群组形成阶段拟定使用的信道号(如信道11)，其他的字节可加载WIFI直连服务信息，用以描述第一设备的服务设置(如音频格式)。当然这里仅为示例说明，而不是对本申请的唯一限定。
可选的，为了避免出现兼容性的问题，本实施例第二设备在接收到第二蓝牙广播消息之后，还可以基于第二蓝牙广播消息中携带的服务设置信息，判断其与第一设备之间传输的数据是否兼容，若兼容则判断与第一设备建立WIFI直连，并执行步骤103。否则，拒绝与第一设备建立直连。
步骤103、第二设备向所述第一设备发送第一蓝牙消息，所述第一蓝牙消息包括所述第二设备的WIFI直连地址。
示例的，本实施例中第一蓝牙消息可以为AUX_SCAN_REQ帧的形式。如图4所示的AUX_SCAN_REQ帧，当AUX_SCAN_REQ帧中标头的第三个Bit(在蓝牙规范中为RFU栏位)的值为预设数值时(本示例中为“1”，实际应用中还可以设置为其他数值)表示该帧中携带的是第二设备的WIFI直连地址，此时数据(标头后)的前六个字节为第二设备的WIFI直连地址。当然此处仅为示例说明而不是对本申请的唯一限定。
当第一设备接收到第一蓝牙消息之后，根据标头中的第三个字节识别第一蓝牙消息中携带有第二设备的WIFI直连地址。第一设备从第一蓝牙消息解析出第二设备的WIFI直连地址后，对该WIFI直连地址进行存储用以在接下来的群体形成过程中使用。
步骤104、第二设备根据所述第一设备的WIFI直连地址和所述第二设备的WIFI直连地址执行WIFI直连操作。
本实施例中，第二设备在将第一蓝牙消息发送给第一设备之后，第二设备可以根据预先设定的信道建立与第一设备之间的WIFI直连，也可以通过协商的方式确定用于建立WIFI直连的信道。
示例的，图5为本申请实施例提供的步骤104的执行方式流程图，如图5所示，步骤104可以包括如下步骤：
步骤1041、第二设备向所述第一设备发送第二蓝牙消息，所述第二蓝牙消息包括所述第二设备的蓝牙MAC地址。
示例的，本实施例中第二蓝牙消息可以被具体为AUX_SCAN_REQ帧的形式。如图6所示的AUX_SCAN_REQ帧，当AUX_SCAN_REQ帧中标头的第三个字节的值(RFU栏 位)为预设值时(本示例中为“0”，实际应用中还可以设置为其他数值)表示该帧中携带的是第二设备的蓝牙MAC地址，此时数据(标头后)的前六个字节为第二设备的蓝牙MAC地址。当然此处仅为示例说明而不是对本申请的唯一限定。
当第一设备接收到第二蓝牙消息之后，根据标头中的第三个字节识别第一蓝牙消息中携带有第二设备的蓝牙MAC地址。第一设备从第二蓝牙消息解析出第二设备的蓝牙MAC地址后，对该蓝牙MAC地址进行存储用以构建接下来要发送的第三蓝牙广播消息。
示例的，本实施例中第三蓝牙消息可以被具体为AUX_SCAN_RSP帧。如图7所示，在图7中AUX_SCAN_RSP帧必要的包括第二信道指针和起始时间，可选的，还可以包括第一设备的WIFI直连地址，以及第一设备的其它服务设置信息。其中，起始时间用于指示第二设备在何时启动群组形成程序。第二信道指针用于指示群组建立时使用的信道。
第一设备在完成发送第三蓝牙消息后即关闭其蓝牙设备，进入WIFI连接，等待群组形成程序。
当然前述示例仅为示例说明而不是对发明的唯一限定。
步骤1042、第二设备在所述蓝牙MAC地址所在的接口上接收所述第一设备的第三蓝牙广播消息，所述第三蓝牙广播消息包括起始时间和第二信道指针。
本实施例中，第二设备在接收到第三蓝牙广播消息之后即关闭其蓝牙设备，此时第二设备可以将第一设备的相关信息(比如名称和WIFI地址)显示给用户，当用户选择第一设备进行Miracast直连时才执行第一设备和第二设备之间的Miracast直连。当然实际应用中，也可以省略向用户显示第一设备的相关信息的步骤，而是由第二设备直接建立第一设备和第二设备之间的Miracast直连。本实施例中不对其做具体的限定。
步骤1043、在所述起始时间到达时，第二设备基于所述第二信道指针指向的信道建立与所述第一设备的WIFI直连。
本实施例，第二设备通过接收第一设备发送的包括第一信道指针的第一蓝牙广播消息，在第一信道指针指向的信道上接收第一设备发送的包含第一设备的WIFI直连地址的第二蓝牙广播消息，向第一设备发送包含第二设备的WIFI直连地址的第一蓝牙消息，并根据第一设备的WIFI直连地址和其自身的WIFI直连地址执行WIFI直连操作。由于本实施例是通过蓝牙广播消息来实现WIFI直连过程中的设备发现和服务发现的，因此，不需要第一设备和第二设备在时间上和信道上通过随机切换的方式来搜索和监听对方，从而缩短了WIFI直连所需的时间，提高了直连效率，降低了由直连超时导致的直连失败的概率。
