当侦测到的所述蓝牙广播信息的信号强度超过预设信号强度时,所述第二蓝牙设备执行与所述第一蓝牙设备进行配对的步骤。
具体的,若所述信号强度超过所述预设信号强度,所述第二蓝牙设备读取蓝牙配对列表,并检测所述蓝牙配对列表中,是否存在配对过的其他蓝牙设备;
若是,则移除其他蓝牙设备的配对;
若否,则所述第二蓝牙设备与所述第一蓝牙设备进行配对。
进一步的,若侦测到的所述蓝牙广播信息的信号强度未超过预设信号强度,则所述第二蓝牙设备向使用者发出信号强度低的提示,并提示用户靠近所述第二蓝牙设备,以提高所述蓝牙广播信息的信号强度。
请参照图5,优选地,在第七实施例中,所述第二蓝牙设备在侦测到所述蓝牙广播信息时,与所述第一蓝牙设备进行配对之后,进一步包括以下步骤:

步骤S131(图未示),若是,则所述第一蓝牙设备对所述第一计时器进行复位,并停止发送所述红外码信息和所述蓝牙广播信息。
在所述第一蓝牙设备收到配对成功信息后,将所述第一计时器复位,同时停止发送所述红外码信息和所述蓝牙广播信息以停止本轮配对服务,有利于自动结束配对服务,节约配对过程中的能源损耗。
优选地,在第九实施例中,所述第一蓝牙设备判断是否收到配对成功信息之后,进一步包括:
步骤S150(图未示),若否,则所述第一蓝牙设备读取所述第一计时器的时间值,并判断所述第一计时器的时间值是否大于预设时间;
若是,则所述第一蓝牙设备对所述第一计时器进行复位,并停止发送所述红外码信息和所述蓝牙广播信息;
若否,则继续执行所述第一蓝牙设备判断是否收到配对成功信息的步骤。
在本实施例中,所述第一计时器的预设时间设置为20s,超过所述第一计时器的预设时间后,自动暂停配对服务,有利于降低持续发起配对服务造成的能源损耗。
此外,为实现上述目的,本发明还提供一种蓝牙设备,参照图6,在一实施例中,本发明提供的蓝牙设备包括:
接收模块11,用于接收第一蓝牙设备在收到触发指令后发送的红外码信息;
侦测模块13,用于在接收所述红外码信息后,侦测所述第一蓝牙设备在发送所述红外码信息之时同时发送的所述蓝牙广播信息;
配对模块15,用于在侦测到所述蓝牙广播信息时,与所述第一蓝牙设备进行配对。
在本实施例中,所述第一蓝牙设备为BLE遥控器,所述蓝牙设备为电视机主机,但是,所述第一蓝牙设备和所述蓝牙设备的实施例并不以此为限。所述触发指令可以通过按压组合按键发送,在收到所述触发指令后,所述红外码信息和所述蓝牙广播信息同时发送。例如,使用者可以将BLE遥控器对准所述电视机主机的所述接收模块11,然后按压所述组合按键,由于红外信息发送和红外信息接收需要在有效范围内才能实现,当有多台电视机主机同时存在时,其他电视机主机不会接收到所述红外码信息并触发所述侦测模块13对所述蓝牙广播信息的扫描,因此,可以避免BLE遥控器与其他电视机主机误配对。
为了优化所述第一蓝牙设备和所述蓝牙设备的对码方法,在第一蓝牙设备发送的蓝牙广播信息中端增加自定义字段,并通过LE Advertising
Report Event广播此字段。
所述自定义字段是针对EIR中Manufacturer Specific
Data的扩展定义,所述自定义字段的基本数据内容如下表所示,包括:数据长度、数据类型、数据内容以及若干个预留位,所述蓝牙设备能通过扫描所述蓝牙广播信息侦测所述第一蓝牙设备。
自定义字段的基本数据内容表
内容 | Struct Length | Assign Name | Vendor ID(1th) | Vendor ID(2rd) | Param1 | Param2 |
字段属性 | 8bit(0x05) | 8bit (0xff) | 8bit (0x88) | 8bit (0x89) | 4bit reserv | 4bit reserv |
所述侦测模块13检测到所述红外码信息后,开始启动自动扫描服务,以在扫描范围内侦测所述蓝牙广播信息。
具体的,所述侦测模块13侦测到所述蓝牙广播信息时,进一步解析所述蓝牙广播信息的自定义字段的内容,以判断所述蓝牙广播信息是否合法,若合法,所述配对模块15方可与所述第一蓝牙设备进行配对,提高所述蓝牙设备对所述第一蓝牙设备的配对准确率。
在本发明的技术方案中,所述第一蓝牙设备接收到触发指令后,在发送红外码信息至所述蓝牙设备的同时,发送蓝牙广播信息,所述蓝牙设备在接收所述红外码信息后开始侦测所述蓝牙广播信息,当同时存在多个蓝牙设备时,仅接收到所述红外码信息的所述蓝牙设备才开始侦测所述蓝牙广播信息以进行配对,可以有效避免蓝牙设备之间的误配对。
进一步的,所述侦测模块13还用于在未侦测到所述蓝牙广播信息时,继续执行侦测所述第一蓝牙设备在发送所述红外码信息之时同时发送的所述蓝牙广播信息。
以上仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
