本公开基于2021年07月26日提交的发明名称为“蓝牙连接方法、蓝牙设备、系统、电子设备及存储介质”的中国专利申请CN202110842351.7，并且要求该专利申请的优先权，通过引用将其所公开的内容全部并入本公开。
本发明涉及蓝牙技术领域，具体涉及一种蓝牙连接方法、蓝牙主设备、蓝牙从设备、蓝牙系统、电子设备及计算机存储介质。
蓝牙技术是一种无线技术标准，可实现固定设备、移动设备和楼宇个人域网之间的短距离数据交换。蓝牙技术的实质内容是建立通用的无线电空中接口，以构建固定设备或移动设备之间的通信环境,将通信技术与计算机技术进一步结合起来,使各种3C设备(通讯产品Communication、电脑产品Computer、消费类电子产品Consumer)在没有电线或电缆相互连接的情况下,能在近距离范围内实现通信及操作。
在蓝牙系统中，多个蓝牙从设备对于蓝牙主设备来说没有区别，各蓝牙从设备均可以连接到主设备，并且在同一时间只能有一个蓝牙从设备连接到蓝牙主设备，但是，这种连接方式这将导致特定的蓝牙从设备无法优先连接到蓝牙主设备。例如在车载蓝牙系统中，若司机的蓝牙设备无法优先连接到车载蓝牙，则无法达到司机解放双手、降低交通肇事隐患的目的，无法保障行车安全性。

本文所述实施例可借助本公开的理想示意图而参考平面图和/或截面图进行描述。因此，可根据制造技术和/或容限来修改示例图示。因此，实施例不限于附图中所示的实施例，而是包括基于制造工艺而形成的配置的修改。因此，附图中例示的区具有示意性属性，并且图中所示区的形状例示了元件的区的具体形状，但并不旨在是限制性的。

本公开实施例提供一种蓝牙连接方法，可以应用于包括蓝牙主设备和至少一个蓝牙从设备的蓝牙系统。如图1所示，当该方法应用于蓝牙主设备时，可以包括如下步骤：
在步骤S11中，根据接收到的连接请求确定发送连接请求的第一蓝牙从设备的标识信息。
在步骤S12中，根据第一蓝牙从设备的标识信息和预存的已配对设备信息确定第一蓝牙从设备的连接权限。
在步骤S13中，根据当前蓝牙主设备的当前连接状态与第一蓝牙从设备的连接权限确定 目标蓝牙连接从设备。
在本公开实施例中，不同蓝牙从设备的标识信息应当不同，以便蓝牙主设备进行区分识别，可以将任何能够用以区分蓝牙从设备的信息作为蓝牙从设备的标识信息。蓝牙从设备可以通过BLE(Bluetooth Low Energy，蓝牙低功耗)协议向蓝牙主设备发送BLE广播消息形式的连接请求，在向蓝牙主设备发送连接请求时，可以在连接请求中携带本设备的标识信息，因此，当接收到第一蓝牙从设备发送的连接请求时，蓝牙主设备可以从中获取到第一蓝牙从设备的标识信息。
蓝牙主设备预存的已配对设备信息，其中记录了任一与当前蓝牙主设备配对过的蓝牙从设备的配置信息，仍根据蓝牙从设备的标识信息区分不同蓝牙从设备的配置信息。因此，蓝牙主设备可以根据第一蓝牙从设备的标识信息和预存的已配对设备信息确定为第一蓝牙从设备配置的连接权限。
蓝牙主设备的当前连接状态可以包括：蓝牙主设备当前是否已与蓝牙从设备建立蓝牙连接、当前已与蓝牙主设备建立蓝牙连接的具体的蓝牙从设备等等。蓝牙主设备可以根据当前连接状态与第一蓝牙从设备的连接权限，比较各请求连接的蓝牙从设备(或各请求连接的蓝牙从设备以及蓝牙主设备当前连接的蓝牙从设备)的连接权限，从中确定出连接权限最高的蓝牙从设备作为目标蓝牙连接从设备，目标蓝牙连接从设备即蓝牙主设备在接收到第一蓝牙从设备发送的连接请求之后、欲与之建立蓝牙连接的蓝牙从设备。在根据当前蓝牙主设备的当前连接状态与第一蓝牙从设备的连接权限确定目标蓝牙连接从设备之后，蓝牙主设备可以与目标蓝牙连接从设备建立蓝牙连接。
通过上述步骤S11-S13可以看出，本公开实施例提供的蓝牙连接方法，根据接收到的连接请求确定发送连接请求的第一蓝牙从设备的标识信息，根据第一蓝牙从设备的标识信息和预存的已配对设备信息确定第一蓝牙从设备的连接权限，根据当前蓝牙主设备的当前连接状态与第一蓝牙从设备的连接权限确定目标蓝牙连接从设备，能够根据蓝牙从设备的标识信息、当前蓝牙主设备的预存的已配对设备信息以及当前连接状态确定出连接权限最高的蓝牙从设备作为目标蓝牙连接从设备，以便蓝牙主设备与目标蓝牙连接从设备建立蓝牙连接，确保特定的蓝牙从设备能够优先连接到蓝牙主设备，提高蓝牙连接的安全性以及蓝牙使用体验。例如可以确保司机的蓝牙从设备优先连接到车载蓝牙，从而达到司机解放双手、降低交通肇事隐患的目的，保障行车安全性，提高蓝牙连接的安全性、车载系统的安全性以及司机的蓝牙使用体验。
发送连接请求的蓝牙从设备，其所有者往往与蓝牙主设备所有者具有一定的联系，例如，蓝牙从设备的所有者可以是蓝牙主设备所有者的家属、朋友等等，蓝牙从设备在向蓝牙主设备发送连接请求时，还可以发送自身的身份信息，如“司机”、“家属”、“朋友”等等，以便蓝牙主设备处理连接请求。相应的，在一些实施例中，所述标识信息至少包括发送所述连接请求的第一蓝牙从设备的身份信息。
除可以将蓝牙从设备的身份信息作为标识信息之外，还可以将地址信息和设备名称作为蓝牙从设备的标识信息，当然，也可以将除身份信息、地址信息、设备名称之外的其他任何能够用以区分蓝牙从设备的信息作为蓝牙从设备的标识信息。
由于在同一时间只能有一个蓝牙从设备连接到蓝牙主设备，目前，若蓝牙主设备当前已与一个蓝牙从设备建立蓝牙连接，其他蓝牙从设备要想与蓝牙主设备建立蓝牙连接，则必须 人为先将蓝牙主设备当前的蓝牙连接断开，再将蓝牙主设备与该其他蓝牙从设备连接。为此，本公开实施例提出，若蓝牙主设备已与蓝牙从设备建立蓝牙连接但又接收到了其他蓝牙从设备发送的连接请求，则蓝牙主设备可以自动比较请求连接的蓝牙从设备的连接权限和当前连接的蓝牙从设备的连接权限，确定出连接权限最高的蓝牙从设备，以便自动与连接权限最高的蓝牙从设备建立蓝牙连接。
相应的，在一些实施例中，所述连接权限包括连接优先级，在所述当前蓝牙主设备的当前连接状态为当前蓝牙主设备已与第二蓝牙从设备建立蓝牙连接的情况下，如图2所示，所述根据当前蓝牙主设备的当前连接状态与所述第一蓝牙从设备的连接权限确定目标蓝牙连接从设备的步骤(即步骤S13)可以包括如下步骤：
在步骤S131中，确定第二蓝牙从设备的连接优先级。
在步骤S132中，在第一蓝牙从设备的连接优先级高于第二蓝牙从设备的连接优先级的情况下，将第一蓝牙从设备确定为目标蓝牙连接从设备。
在当前蓝牙主设备已与蓝牙从设备建立蓝牙连接、且蓝牙主设备当前连接的具体的蓝牙从设备为第二蓝牙从设备的情况下，蓝牙主设备可以进一步确定第二蓝牙从设备的连接优先级，具体的，蓝牙主设备可以根据第二蓝牙从设备的标识信息查询预存的已配对设备信息，确定为第二蓝牙从设备配置的连接优先级。
确定出第一蓝牙从设备的连接优先级以及第二蓝牙从设备的连接优先级之后，蓝牙主设备可以将第一蓝牙从设备的连接优先级与第二蓝牙从设备的连接优先级进行比较，在第一蓝牙从设备的连接优先级高于第二蓝牙从设备的连接优先级的情况下，可以将第一蓝牙从设备确定为目标蓝牙连接从设备。
应当理解，若发送连接请求的蓝牙从设备为多个，当其中任一蓝牙从设备的连接优先级高于第二蓝牙从设备的连接优先级时，可以将该“任一蓝牙从设备”确定为目标蓝牙连接从设备；若连接优先级高于第二蓝牙从设备的连接优先级的第一蓝牙从设备为多个，可以将连接优先级高于第二蓝牙从设备的连接优先级的多个第一蓝牙从设备中最早发送连接请求的第一蓝牙从设备确定为目标蓝牙连接从设备。
通过上述步骤S131-S132可以看出，本公开实施例提供的蓝牙连接方法，若当前蓝牙主设备已与第二蓝牙从设备建立蓝牙连接，则确定第二蓝牙从设备的连接优先级，在第一蓝牙从设备的连接优先级高于第二蓝牙从设备的连接优先级的情况下，将第一蓝牙从设备确定为目标蓝牙连接从设备。蓝牙主设备自动比较请求连接的蓝牙从设备的连接优先级和已连接的蓝牙从设备的连接优先级，确定出连接优先级最高的蓝牙从设备作为目标蓝牙连接从设备，无论特定的蓝牙从设备是作为已与蓝牙主设备建立蓝牙连接的第二蓝牙从设备，还是作为请求与蓝牙主设备建立蓝牙连接的第一蓝牙从设备，均能够自动且快速被蓝牙主设备确定为目标蓝牙连接从设备，进而优先与蓝牙主设备建立蓝牙连接，无需手动在多个蓝牙从设备之间切换连接，提高蓝牙连接的安全性以及蓝牙使用体验。
若蓝牙主设备已与第二蓝牙从设备建立蓝牙连接且又接收到第一蓝牙从设备发送的连接请求，则在将第一蓝牙从设备确定为目标蓝牙连接从设备之后，为与目标蓝牙连接从设备建立蓝牙连接，蓝牙主设备可以首先自动断开与第二蓝牙从设备的蓝牙连接，再与第一蓝牙从设备建立蓝牙连接。相应的，在一些实施例中，在将第一蓝牙从设备确定为目标蓝牙连接从设备的步骤(即步骤S132)之后，所述方法还可以包括如下步骤：断开与第二蓝牙从设备的 蓝牙连接。相应的，在断开与第二蓝牙从设备的蓝牙连接之后，蓝牙主设备可以与目标蓝牙连接从设备建立蓝牙连接。
由于在同一时间只能有一个蓝牙从设备连接到蓝牙主设备，目前，若蓝牙主设备当前未与任意蓝牙从设备建立蓝牙连接，且接收到多个蓝牙从设备发送的连接请求，则蓝牙主设备将响应最早发送的连接请求，与最早发送连接请求的蓝牙从设备建立蓝牙连接。这将导致特定的蓝牙从设备无法优先连接到蓝牙主设备。为此，本公开实施例提出，若蓝牙主设备未与任意蓝牙从设备建立蓝牙连接但又接收到了多个蓝牙从设备发送的连接请求，则蓝牙主设备可以自动比较各个请求连接的蓝牙从设备的连接权限，确定出连接权限最高的蓝牙从设备，以便自动与连接权限最高的蓝牙从设备建立蓝牙连接。
相应的，在一些实施例中，所述连接权限包括连接优先级，在所述第一蓝牙从设备为多个、且所述当前蓝牙主设备的当前连接状态为当前蓝牙主设备未与任意蓝牙从设备建立蓝牙连接的情况下，所述根据当前蓝牙主设备的当前连接状态与所述第一蓝牙从设备的连接权限确定目标蓝牙连接从设备的步骤(即步骤S13)可以包括如下步骤：将各第一蓝牙从设备中连接优先级最高的第一蓝牙从设备确定为目标蓝牙连接从设备。相应的，在将各第一蓝牙从设备中连接优先级最高的第一蓝牙从设备确定为目标蓝牙连接从设备之后，蓝牙主设备可以与目标蓝牙连接从设备建立蓝牙连接。
若发送连接请求的第一蓝牙从设备为多个且当前蓝牙主设备未与任意蓝牙从设备建立蓝牙连接，则将各第一蓝牙从设备中连接优先级最高的第一蓝牙从设备确定为目标蓝牙连接从设备，以便蓝牙主设备与目标蓝牙连接从设备建立蓝牙连接，确保特定的蓝牙从设备能够优先连接到蓝牙主设备，提高蓝牙连接的安全性以及蓝牙使用体验。例如可以确保司机的蓝牙从设备优先连接到车载蓝牙，从而达到司机解放双手、降低交通肇事隐患的目的，保障行车安全性，提高蓝牙连接的安全性、车载系统的安全性以及司机的蓝牙使用体验。
各蓝牙从设备均具有唯一的MAC(Mandatory Access Control，强制访问控制)地址，且不同的蓝牙从设备MAC地址也不同，因此可以将蓝牙从设备的MAC地址作为蓝牙从设备的标识信息，并在预存的已配对设备信息中根据蓝牙从设备的MAC地址区分不同蓝牙从设备的配置信息。相应的，在一些实施例中，所述标识信息包括MAC地址，所述已配对设备信息包括与当前蓝牙主设备配对过的各蓝牙从设备的MAC地址与连接优先级之间的对应关系，所述根据确定的标识信息和预存的已配对设备信息确定所述第一蓝牙从设备的连接权限的步骤(即步骤S12)可以包括如下步骤：根据确定的第一蓝牙从设备的MAC地址查询对应关系，以确定第一蓝牙从设备的连接权限。
蓝牙主设备预存有已配对设备信息，其中记录了任一与当前蓝牙主设备配对过的蓝牙从设备的配置信息，仍根据蓝牙从设备的标识信息区分不同蓝牙从设备的配置信息。因此每当有蓝牙从设备与蓝牙主设备配对成功后，蓝牙主设备均可以更新已配对设备信息。相应的，在一些实施例中，如图3所示，所述方法还可以包括如下步骤：
在步骤S21中，响应于接收到配对请求，对配对请求中携带的安全验证信息进行验证。
在步骤S22中，当验证通过时，根据配对请求中携带的标识信息更新已配对设备信息。
其中，蓝牙从设备发送的配对请求是基于用户输入的安全指令生成的。在本公开实施例中，蓝牙从设备可以与蓝牙主设备预先约定与PIN不同的安全验证信息，蓝牙从设备在请求与蓝牙主设备配对时，也可以提供安全验证信息。在安全验证信息与当前蓝牙主设备预存的 与该蓝牙从设备对应的安全验证信息一致的情况下，可以认为该蓝牙从设备的身份合法，安全验证信息通过验证。此时蓝牙主设备可以通过该配对请求，并且根据配对请求中携带的标识信息在已配对设备信息中添加发送该配对请求的蓝牙从设备的配置信息。
特定的蓝牙从设备的所有者，往往也是蓝牙主设备的所有者，或者往往也是蓝牙主设备的使用频率最高者。蓝牙主设备预存的已配对设备信息中记录了为与当前蓝牙主设备配对过的各蓝牙从设备的连接权限，特定的蓝牙从设备在与蓝牙主设备建立蓝牙连接之后，可以修改其他蓝牙从设备的连接权限，以保证蓝牙连接的安全性以及蓝牙使用体验。
相应的，在一些实施例中，所述已配对设备信息包括与当前蓝牙主设备配对过的各蓝牙从设备的标识信息与连接权限的对应关系，所述连接权限包括连接优先级，如图4所示，所述方法还可以包括如下步骤：
在步骤S31中，响应于接收到第三蓝牙从设备发送的权限更新请求，根据权限更新请求更新已配对设备信息中相应的连接权限；其中，第三蓝牙从设备为与当前蓝牙主设备配对过的各蓝牙从设备中连接优先级最高的蓝牙从设备。
需要说明的是，本公开实施例以第一蓝牙从设备指代发送连接请求的蓝牙从设备，以第二蓝牙从设备指代蓝牙主设备当前连接的蓝牙从设备，以第三蓝牙从设备指代连接优先级最高的蓝牙从设备，如前所述的第一蓝牙从设备或第二蓝牙从设备，均可以同时作为第三蓝牙从设备的角色而存在。
在本公开实施例中，已配对设备信息中记录的为与当前蓝牙主设备配对过的各蓝牙从设备的连接权限，除包括连接优先级之外，还可以包括操作权限。操作权限即蓝牙从设备在与蓝牙主设备建立蓝牙连接之后所能通过蓝牙主设备执行的各项操作的权限，各项操作可以包括：打开/关闭车门、通话、播放歌曲、设置为黑名单等等。蓝牙主设备在根据配对请求中携带的标识信息更新已配对设备信息时，可以根据各蓝牙从设备的标识信息将其连接权限设置为默认权限。
例如，车载蓝牙可以根据如图5所示的默认权限分配表以及各蓝牙从设备发送的配对请求中携带的标识信息，在已配对设备信息中添加各蓝牙从设备的连接权限。标识信息可以包括身份信息，即蓝牙从设备所有者的身份信息，例如“司机”、“家属”、“朋友”等等。如图5所示，可以根据蓝牙从设备的身份信息设置默认权限，身份信息不同的蓝牙从设备可以有不同的默认权限，司机的蓝牙从设备具有最高的默认权限，连接优先级第一且具有打开/关闭车门、通话、播放歌曲和禁止设置为黑名单等操作权限，司机所有家属的(即身份信息包括“家属”的)蓝牙从设备连接优先级第二且具有通话、播放歌曲和未设置为黑名单等操作权限，司机所有朋友的(即身份信息包括“朋友”的)蓝牙从设备连接优先级第三且具有通话、播放歌曲和未设置为黑名单等操作权限，其他蓝牙从设备连接优先级第四且具有播放歌曲和未设置为黑名单等操作权限。车载蓝牙的已配对设备信息可以做如图6所示的设置，如图6所示，已配对设备可以包括司机、第一家属、第二家属和其他用户的蓝牙从设备，蓝牙从设备的标识信息可以包括身份信息、MAC地址和设备名称，权限详情可以是如图5所示的默认权限，当然，也可以由车载蓝牙或司机的蓝牙从设备自定义设置。
当蓝牙从设备请求通过蓝牙主设备执行操作时，蓝牙主设备可以根据已配对设备信息中的连接权限处理蓝牙从设备的操作请求。相应的，在一些实施例中，所述标识信息包括身份信息，所述连接权限还包括操作权限，如图7所示，所述方法还可以包括如下步骤：
在步骤S41中，根据接收到的操作请求确定发送操作请求的第四蓝牙从设备的身份信息，其中，第四蓝牙从设备为当前与当前蓝牙主设备建立蓝牙连接的蓝牙从设备。
在步骤S42中，根据第四蓝牙从设备的身份信息和已配对设备信息确定第四蓝牙从设备的操作权限。
在步骤S43中，根据第四蓝牙从设备的操作权限处理操作请求。
蓝牙从设备可以通过BLE协议向蓝牙主设备发送BLE广播消息形式的操作请求，在向蓝牙主设备发送操作请求时，可以在操作请求中携带本设备的标识信息，标识信息包括身份信息，因此，当接收到第四蓝牙从设备发送的操作请求时，蓝牙主设备可以从中获取到第四蓝牙从设备的身份信息。在已配对设备信息中，蓝牙主设备根据蓝牙从设备的身份信息设置了默认的或自定义的连接权限，身份信息不同的蓝牙从设备可以有不同的连接权限。已配对设备信息包括与当前蓝牙主设备配对过的各蓝牙从设备的身份信息与连接权限的对应关系，蓝牙主设备可以根据第四蓝牙从设备的身份信息查询该对应关系，以确定第四蓝牙从设备的操作权限，当确定出第四蓝牙从设备具有其所请求执行的操作的权限时，对其发送的操作请求可予以通过。
需要说明的是，本公开实施例以第四蓝牙从设备指代当前与蓝牙主设备蓝牙连接且向蓝牙主设备发送操作请求的蓝牙从设备，如前所述的第二蓝牙从设备，也可以同时作为第四蓝牙从设备的角色而存在。
通过上述步骤S41-S43可以看出，本公开实施例提供的蓝牙连接方法，通过在已配对设备信息中为与当前蓝牙主设备配对过的各蓝牙从设备配置连接权限，当接收到蓝牙从设备发送的操作请求时，根据蓝牙从设备的标识信息和已配对设备信息确定蓝牙从设备的操作权限，根据蓝牙从设备的操作权限处理操作请求，则不同的蓝牙从设备在与蓝牙主设备建立蓝牙连接之后能通过蓝牙主设备执行不同的操作，并且能够实现特定的蓝牙从设备可以通过蓝牙主设备执行最多的操作，提高蓝牙连接的安全性以及蓝牙使用体验。
若蓝牙主设备为车载蓝牙，当蓝牙从设备搜索车载蓝牙以便与车载蓝牙建立蓝牙连接时，由于现有的蓝牙设备所显示的蓝牙图标通常情况下是一致的，车载蓝牙显示的蓝牙图标与其他蓝牙主设备显示的蓝牙图标没有区别，用户无法非常准确快速地分辨出车载蓝牙，因此车载蓝牙可以显示与现有蓝牙图标不同的车载蓝牙图标，便于蓝牙从设备准确快速地与车载蓝牙建立蓝牙连接。相应的，在一些实施例中，所述方法还可以包括如下步骤：响应于接收到蓝牙搜索请求，控制当前蓝牙主设备的显示面板显示车载蓝牙图标。
应当理解，不同的蓝牙从设备也可以显示不同的蓝牙图标，以便蓝牙主设备进行区分。
本公开实施例提供的蓝牙连接方法，不仅能够应用于蓝牙主设备，而且能够应用于蓝牙从设备。相应的，如图8所示，当本公开实施例提供的蓝牙连接方法应用于蓝牙从设备时，可以包括如下步骤：
在步骤S51中，向蓝牙主设备发送连接请求，以供蓝牙主设备根据连接请求中携带的标识信息、蓝牙主设备预存的已配对设备信息和当前连接状态处理连接请求。
蓝牙从设备可以通过BLE(Bluetooth Low Energy，蓝牙低功耗)协议向蓝牙主设备发送BLE广播消息形式的连接请求，在向蓝牙主设备发送连接请求时，可以在连接请求中携带本设备的标识信息，蓝牙从设备可以根据接收到的连接请求确定发送连接请求的蓝牙从设备的标识信息，根据蓝牙从设备的标识信息和预存的已配对设备信息确定蓝牙从设备的连接权 限，根据当前蓝牙主设备的当前连接状态与蓝牙从设备的连接权限确定目标蓝牙连接从设备。
特定的蓝牙从设备的所有者，往往也是蓝牙主设备的所有者，或者往往也是蓝牙主设备的使用频率最高者。蓝牙主设备预存的已配对设备信息中记录了为各与当前蓝牙主设备配对过的各蓝牙从设备的连接权限，特定的蓝牙从设备在与蓝牙主设备建立蓝牙连接之后，可以修改其他蓝牙从设备的连接权限，以保证蓝牙连接的安全性以及蓝牙使用体验。相应的，在一些实施例中，所述方法还可以包括如下步骤：在当前蓝牙从设备已与蓝牙主设备建立蓝牙连接的情况下，向蓝牙主设备发送权限更新请求，以更新蓝牙主设备预存的已配对设备信息。
在当前蓝牙从设备已与蓝牙主设备建立蓝牙连接的情况下，向蓝牙主设备发送权限更新请求，以更新蓝牙主设备预存的已配对设备信息，特定的蓝牙从设备在与蓝牙主设备建立蓝牙连接之后，可以修改其他蓝牙从设备的连接权限，提高蓝牙连接的安全性以及蓝牙使用体验。
蓝牙从设备与蓝牙主设备的首次配对往往需要通过PIN(Personal Identification Number，个人识别密码)进行验证。PIN仅由4到6位数字构成，在生成之后由蓝牙从设备使用E2或E3加密算法进行加密，然后传输给蓝牙主设备进行认证。携带加密后的PIN的数据包容易被攻击从而导致PIN被破解以及蓝牙从设备的标识信息被窃取。蓝牙从设备可以与蓝牙主设备预先约定与PIN不同的安全验证信息，如私人密码、指纹、人脸识别信息等等，在蓝牙从设备请求与蓝牙主设备配对时，要求蓝牙从设备提供安全验证信息以验证其身份。相应的，在一些实施例中，如图9所示，所述方法还包括如下步骤：
在步骤S61中，根据外部输入的安全指令生成配对请求。
在步骤S62中，向蓝牙主设备发送配对请求，以供蓝牙主设备对配对请求中携带的安全验证信息进行验证并当验证通过时根据配对请求中携带的标识信息更新已配对设备信息。
蓝牙主设备在确定出蓝牙从设备发送的安全验证信息和当前蓝牙主设备预存的与该蓝牙从设备对应的安全验证信息一致时，可以认为蓝牙从设备的身份合法，安全验证信息通过验证。从而通过蓝牙从设备的配对请求，并且根据配对请求中携带的标识信息在已配对设备信息中添加蓝牙从设备的配置信息。
基于相同的技术构思，本公开实施例还提供一种蓝牙主设备，如图10所示，所述蓝牙主设备可以包括：
接收模块101，设置为接收连接请求。
标识处理模块102，设置为根据接收模块接收到的连接请求确定发送连接请求的第一蓝牙从设备的标识信息。
权限处理模块103，设置为根据第一蓝牙从设备的标识信息和预存的已配对设备信息确定第一蓝牙从设备的连接权限。
