具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种连接蓝牙设备的方法。参照图1，在第一实施例中，该方法包括：
步骤S10，在主设备的蓝牙功能开启时，扫描并确定周围的可连接的蓝牙设备；
步骤S20，获取所述蓝牙设备与所述主设备的连接历史记录信息，并根据所述历史记录信息对所述蓝牙设备进行排序；及
步骤S30，根据所述排序控制所述主设备自动连接所述蓝牙设备。
本发明提供的连接蓝牙设备的方法用于在主设备蓝牙开启时自动快速连接从属蓝牙设备。其中，主设备与蓝牙设备都是带有蓝牙模块，具备蓝牙功能的蓝牙设备，例如，智能电视、智能手机、蓝牙音箱等蓝牙设备。主设备是主动发送蓝牙连接请求的设备，从属设备是接收蓝牙连接请求的设备。
本实施例中在主设备的蓝牙功能开启时，扫描并确定周围的可连接的蓝牙设备，具体是初始化蓝牙协议，启动蓝牙协议栈，扫描周围的蓝牙设备，当扫描到存在可连接的从属设备时，获取扫描到的可连接的从属设备的设备信息，具体是将扫描到的可连接的从属设备的设备信息更新到内存中，其设备信息可以包括蓝牙设备名称、地址、类型等。
上述蓝牙设备与主设备的连接历史记录信息是主设备与蓝牙设备连接的历史记录信息，历史记录信息可以保存在预置的文件中，例如保存在XML文件中，则历史记录信息是根据XML文件的格式保存的。
当获取到蓝牙设备与主设备的连接历史记录信息后，根据历史记录信息对蓝牙设备进行排序，再根据排序控制主设备自动连接蓝牙设备。具体的历史记录信息中可以包括连接的时间、连接次数等蓝牙连接相关的参数，根据这些历史连接参数来对蓝牙设备进行排序，使得在连接时按照一定的顺序进行连接。
本发明实施例在主设备的蓝牙功能开启时，扫描并确定周围的可连接的蓝牙设备；获取所述蓝牙设备与所述主设备的连接历史记录信息，并根据所述历史记录信息对所述蓝牙设备进行排序；及，根据所述排序控制所述主设备自动连接所述蓝牙设备。由于主设备在进行蓝牙连接时根据历史记录信息对可连接的蓝牙设备进行了排序，使得主设备在进行蓝牙连接时效率更高，实现了快速自动连接蓝牙设备的目的。
参考图2，基于上述图1所示的本发明连接蓝牙设备的方法第一实施例，提出本发明连接蓝牙设备的方法第二实施例，本实施例中，上述步骤S20包括：
步骤S210，根据所述蓝牙设备与所述主设备最近一次建立蓝牙连接的连接时间，赋予所述蓝牙设备第一权重值，其中，所述连接时间越近，则所述第一权重值越大；
步骤S220，根据预设时间内所述蓝牙设备与所述主设备蓝牙连接的连接时长和连接次数，赋予所述蓝牙设备第二权重值，其中，所述连接时长越长，所述连接次数越多，则所述第二权重值越大；
步骤S230，根据所述第一权重值和所述第二权重值，对所述蓝牙设备进行排序。
本实施例根据历史记录信息对蓝牙设备进行排序，其中，历史记录信息包括：蓝牙设备与主设备建立蓝牙连接的连接时间、每一次蓝牙连接的连接时长、预设时间内的连接次数。
根据蓝牙设备与主设备最近一次建立蓝牙连接的连接时间，赋予蓝牙设备第一权重值，连接时间越近，第一权重值越大。例如，历史记录信息中蓝牙设备AAA与BBB的连接时间分别为18:34:01 31/08/2015与10:30:00 30/08/2015，则对AAA设备与BBB设备赋予其第一权重值，且AAA的第一权重值大于设备BBB的第一权重值，具体的第一权重值的大小可以根据需要设定。
根据预设时间内蓝牙设备与主设备蓝牙连接的连接时长和连接次数，赋予蓝牙设备第二权重值，其中，连接时间越长，连接次数越多，则第二权重值越大。其中预设时间可以根据需要进行设定，例如可以设定为30天内，则判断24*3600*30时间内设备的连接时长和连接次数，对于超过预设时间都没有进行过蓝牙连接的设备可以设置权重系数为预设值，也可以不对其进行排序，具体可以根据需要选择，其中预设时间的值可以根据需要设定。其中连接时间可以为平均连接时间，也可以为最后一次连接的连接时长，具体可以根据需要设定。例如历史记录信息中蓝牙设备AAA的次数和连接时间分别为6次，最后一次连接时间为3分钟，蓝牙设备BBB的次数和连接时间分别为5次，最后一次连接时间为3分钟，则蓝牙设备AAA的第二权重值大于蓝牙设备BBB的第二权重值，具体的第二权重值的大小可以根据需要设定。
其中，若蓝牙设备AAA的连接次数大于蓝牙设备BBB，但蓝牙设备AAA的连接时间小于蓝牙设备BBB的连接时间，赋值时，蓝牙设备AAA的第二权重值可以大于、小于也可以等于蓝牙设备BBB的第二权重值，具体可以根据需要设定。
其中，上述步骤S210与步骤S220的顺序可以为S210在前执行，也可以步骤S220在后执行，也可以步骤S210与步骤S220并行执行。
当为蓝牙设备赋予了第一权重值与第二权重值以后，根据第一权重值和第二权重值，对蓝牙设备进行排序。其中，在对蓝牙设备进行赋值时，扫描到的所有可连接的蓝牙设备，可以仅对于存在历史记录信息的蓝牙设备进行权重值的计算和赋值，对于扫描到的蓝牙设备，但是该蓝牙设备不存在历史记录信息，即该蓝牙设备可能从未与主设备进行过连接，可以不计算权重，或者是将该类设备赋予定值或是排列在最后，具体可以根据需要设置扫描到的且未有过历史连接记录的蓝牙设备。
例如，当扫描到AAA、BBB、CCC、DDD四个设备时，若历史记录信息中存在设备AAA与设备BBB，将设备AAA与设备BBB根据历史记录信息进行排序，对设备CCC与设备DDD不进行排序，或将设备CCC与设备DDD的权重值设置为0。
例如，历史记录信息保存在文件名为bt_device.xml的XML文件中。XML文件中的具体内容为：
<bt_devices>
<device value = "0">
<bd_addr>41:00:00:00:16:DF:</bd_addr> //设备地址
<device_name>AAA</device_name> //设备名称
<class_of_device>24</class_of_device> //设备类型
<count>20<count> //设备连接次数
<last_timer>18:34:01 31/08/2015<last_timer> //设备最后一次连接时间
<last_connect_time>180s< last_connect_time> //最后一次连接时长
<last_time>0<last_time> //最后一次连接设备 1:是 0:否
</device>
<device value = "1">
<bd_addr>00:00:00:00:17:DE:</bd_addr>
<device_name>BBB</device_name>
<class_of_device>24</class_of_device>
<count>4<count>
<last_timer>15:34:01 31/07/2015<last_timer>
<last_connect_time>300s< last_connect_time>
<last_time>1<last_time>
</device>
<device value = "2">
<bd_addr>00:00:20:10:17:DE:</bd_addr>
<device_name>CCC</device_name>
<class_of_device>24</class_of_device>
<count>5<count>
<last_timer>15:34:01 15/08/2015<last_timer>
<last_connect_time>100s< last_connect_time>
<last_time>0<last_time>
</device>
<device value = "3">
<bd_addr>7C:1E:52:AA:F1:37:</bd_addr>
<device_name>DDD</device_name>
<class_of_device>25</class_of_device>
<last_timer>15:34:01 28/07/2015<last_timer>
<last_connect_time>180s< last_connect_time>
<count>1<count>
</device>
</bt_devices>
当主设备扫描到的设备有设备AAA、设备BBB、设备CCC和设备DDD时，根据历史记录信息，为扫描到的上述四个设备赋予权重值，根据历史记录信息，四个设备的第一权重值的从大到小为：设备AAA的第一权重值>设备CCC的第一权重值>设备BBB的第一权重值>设备DDD的第一权重值，因为设备AAA与主设备最近一次建立蓝牙的连接时间最近，设备DDD与主设备最近一次建立蓝牙的连接时间最远。例如将设备AAA、设备BBB、设备CCC和设备DDD的第一权重值可以分别设置为0.08、0.06、0.04、0.02。
根据历史预设时间内蓝牙设备与主设备蓝牙连接时长和连接次数，赋予蓝牙设备第二权重值，其过程与上述赋予第一权重值过程类似，不再赘述。
当赋予了权重值以后，可以对蓝牙设备进行排序，具体的，在排序时，根据第一权重值和第二权重值再结合预置的公式进行计算，如公式P=Am%+Bn%，其中A为第一权重值，B为第二权重值，m和n分别为预置的比例系数，m%+n%=100%，P为计算得到的顺序系数，可以根据P的从大到小进行排序，以使最近一次连接的，连接次数最多的，连接时间最长的，设备优先被连接。也可以令P=A* last_connect_time+B*count，其中A和B分别为第一权重值和第二权重值。具体的得到第一权重值和第二权重值以后计算的方法可以根据需要设定。
本实施例通过根据蓝牙设备与主设备最近一次建立蓝牙连接的连接时间，赋予蓝牙设备第一权重值，根据预设时间内蓝牙设备与主设备蓝牙连接的连接时长和连接次数，赋予蓝牙设备第二权重值，再根据第一权重值和第二权重值对蓝牙设备进行排序，使得蓝牙设备在连接时，能够优先连接用户期望连接的设备，加快用户建立蓝牙连接的速度，提高用户体验。
参考图3，基于上述图1所示的本发明连接蓝牙设备的方法第一实施例，提出本发明连接蓝牙设备的方法第三实施例，本实施例中，上述步骤S30包括：
步骤S310，根据所述排序获取所述蓝牙设备信息，并判断所述蓝牙设备是否均为可接受所述主设备的蓝牙连接请求并与之建立蓝牙连接的蓝牙设备；若是，执行步骤S320；
步骤S320，根据所述排序控制所述主设备自动连接所述蓝牙设备。
本实施例中，当对蓝牙设备排序后，获取蓝牙设备信息，具体的，可以获取蓝牙设备的名称、地址、类型等，具体获取哪些信息根据需要设定。
当获取到蓝牙设备信息后，判断蓝牙设备是否为可接受主设备的蓝牙连接请求并与之建立蓝牙连接的蓝牙设备。具体的判断方法可以通过获取蓝牙设备的类型来进行判断。具体的，在建立连接时，根据排列顺序，控制主设备先向排列顺序在第一位的蓝牙设备发送连接请求，当接收到蓝牙连接成功的消息时，确认主设备与排列第一位的蓝牙设备建立蓝牙连接成功。若主设备与排列第一位的蓝牙设备没有建立蓝牙连接成功，则控制主设备与排列第二位的设备建立蓝牙连接。
若均为可接受主设备的蓝牙连接请求并与之建立蓝牙连接的蓝牙设备，则根据排序控制主设备自动连接蓝牙设备。例如设备AAA、设备BBB、设备CCC及设备DDD全部都为可以接受主设备的蓝牙连接请求并能够与主设备进行蓝牙连接的蓝牙设备，其排列顺序为：设备AAA>设备CCC>设备BBB >设备DDD，则在连接时，根据排列顺序先与设备AAA建立蓝牙连接，具体的，主设备向设备AAA发送蓝牙连接请求，若接收到蓝牙连接建立成功的消息，则确认主设备与设备AAA的蓝牙连接建立成功，若主设备与设备AAA连接失败，则向设备CCC发送蓝牙连接请求。
本实施例通过排序后获取蓝牙设备信息，并判断蓝牙设备是否均为可接收主设备的蓝牙连接请求并与之建立蓝牙连接的设备，若是，则根据排序控制主设备自动连接蓝牙设备，使得主设备在自动连接周围的蓝牙设备时，能够根据排列顺序进行连接，提高自动连接的速度。
基于上述图3所示的本发明连接蓝牙设备的方法第三实施例，提出本发明连接蓝牙设备的方法第四实施例，本实施例中，若所述蓝牙设备不是均为可接受所述主设备的蓝牙连接请求并与该主设备建立蓝牙连接的蓝牙设备，则从所述排序中删除无法接受所述主设备的蓝牙连接请求并与该主设备建立蓝牙连接的蓝牙设备。
本实施例中，若存在蓝牙设备不能接收主设备的蓝牙连接请求且不能与该主设备建立蓝牙连接的蓝牙设备时，将该蓝牙设备从排列顺序中删除。由于有些蓝牙设备无法接收蓝牙请求建立连接，只能通过主动发送蓝牙连接请求的方式建立蓝牙连接，因此若主动连接该设备，则经过一段等待时间会接收到连接失败的反馈，在这种情况下，自动连接蓝牙设备的时间变长了，因此在这里，将不能够接收主设备的蓝牙连接请求且不能与该主设备建立蓝牙连接的蓝牙设备进行删除，使得在蓝牙连接时提高蓝牙连接的效率。
通过此种方法也可以通过筛选仅连接想要连接的蓝牙类型，例如仅连接音频类型的蓝牙设备，若检测到鼠标类型的蓝牙设备，不进行连接。则在连接时判断蓝牙设备是否为预置的蓝牙类型，若是，则进行连接，若否，则在排序中删除该设备。
例如，当检测到的设备AAA、设备BBB、设备CCC的设备类型为24，设备DDD的设备类型为25，其中24类型表示该设备为音频，25类型表示该设备为鼠标，当希望仅连接音频设备时，将设备DDD从排序中删除，仅连接设备AAA、设备BBB和设备CCC，则连接时根据AAA>设备CCC>设备BBB的顺序进行自动连接。
本实施例通过当排序后的蓝牙设备中存在无法接收主设备的蓝牙连接请求或与该主设备建立蓝牙连接的蓝牙设备，则从排序中将该设备删除，此时主设备根据排列顺序自动连接蓝牙设备时，由于删除了无法连接的蓝牙设备，使得连接的时候减少了连接等待时间，提高了蓝牙连接的连接速度和效率。
参考图4，基于本发明连接蓝牙设备的方法上述实施例，提出本发明连接蓝牙设备的方法第五实施例，本实施例中，本发明提出的连接蓝牙设备的方法还包括：
步骤S40，在所述主设备按所述排序自动连接所述蓝牙设备后，实时记录所述蓝牙设备与所述主设备之间蓝牙连接信息，并保存至所述历史记录信息，其中，所述蓝牙连接信息包括：所述蓝牙连接的连接时间、所述蓝牙连接的连接时长、以及所述蓝牙连接的连接次数。
本实施例中在主设备按排序自动连接蓝牙设备后，实时记录连接信息。具体的是在主设备与周围某一蓝牙设备建立蓝牙成功时，相关连接信息，将连接信息保存至历史记录信息，具体是按照历史记录信息的文件格式进行存储，例如历史记录信息保存在XML格式的文件中时，将连接信息以XML文件格式进行存储。
蓝牙连接信息包括，蓝牙连接的连接时间、蓝牙连接的连接时长以及蓝牙连接的连接次数。具体的，例如当设备BBB与主设备建立蓝牙连接成功时，将蓝牙连接信息更新至历史记录信息，当设备BBB与主设备建立蓝牙连接5分钟又断开后，获取其连接时间为15:34:01 31/09/2015，连接时长为300s，连接次数为在历史连接次数上累加，若之前连接次数为5，则更新后为6。
具体的，历史记录信息中设备BBB的连接信息在bt_device.xml文件中,更新为:
<device value = "1">
<bd_addr>00:00:00:00:17:DE:</bd_addr>
<device_name>BBB</device_name>
<class_of_device>24</class_of_device>
<count>5<count>
<last_timer>15:34:01 31/09/2015<last_timer>
<last_connect_time>300s< last_connect_time>
<last_time>1<last_time>
可以理解的是，蓝牙连接信息除了可以包括以上连接信息还可以在蓝牙设备更改了蓝牙设备名称时，再次保存该蓝牙设备的蓝牙名称等其他信息。
当历史记录信息根据最新的蓝牙连接情况进行更新后，主设备再次进行蓝牙连接时，可以根据最新的历史记录信息进行排序，从而进行自动连接。
本实施例通过在主设备按排列顺序自动连接蓝牙设备后，实时记录蓝牙设备与主设备之间蓝牙连接信息，并保存至历史记录信息中，使得历史记录信息根据最新的蓝牙连接情况进行更新，使得再次进行连接时，可以根据最新的历史记录信息进行排序，提高主设备蓝牙自动连接的速度。

本发明提供的连接蓝牙设备的装置用于在主设备蓝牙开启时自动快速连接从属蓝牙设备。其中，主设备与蓝牙设备都是带有蓝牙模块，具备蓝牙功能的蓝牙设备，例如，智能电视、智能手机、蓝牙音箱等蓝牙设备。主设备是主动发送蓝牙连接请求的设备，从属设备是接收蓝牙连接请求的设备。

上述蓝牙设备与主设备的连接历史记录信息是主设备与蓝牙设备连接的历史记录信息，历史记录信息可以保存在预置的文件中，例如保存在XML文件中，则历史记录信息是根据XML文件的格式保存的。
当获取到蓝牙设备与主设备的连接历史记录信息后，控制模块30根据历史记录信息对蓝牙设备进行排序，再根据排序控制主设备自动连接蓝牙设备。具体的历史记录信息中可以包括连接的时间、连接次数等蓝牙连接相关的参数，根据这些历史连接参数来对蓝牙设备进行排序，使得在连接时按照一定的顺序进行连接。
本发明实施例在主设备的蓝牙功能开启时，扫描并确定周围的可连接的蓝牙设备；获取所述蓝牙设备与所述主设备的连接历史记录信息，并根据所述历史记录信息对所述蓝牙设备进行排序；及，根据所述排序控制所述主设备自动连接所述蓝牙设备。由于主设备在进行蓝牙连接时根据历史记录信息对可连接的蓝牙设备进行了排序，使得主设备在进行蓝牙连接时效率更高，实现了快速自动连接蓝牙设备的目的。

本实施例根据历史记录信息对蓝牙设备进行排序，其中，历史记录信息包括：蓝牙设备与主设备建立蓝牙连接的连接时间、每一次蓝牙连接的连接时长、预设时间内的连接次数。
第一赋值单元210根据蓝牙设备与主设备最近一次建立蓝牙连接的连接时间，赋予蓝牙设备第一权重值，连接时间越近，第一权重值越大。例如，历史记录信息中蓝牙设备AAA与BBB的连接时间分别为18:34:01 31/08/2015与10:30:00 30/08/2015，则对AAA设备与BBB设备赋予其第一权重值，且AAA的第一权重值大于设备BBB的第一权重值，具体的第一权重值的大小可以根据需要设定。

其中，若蓝牙设备AAA的连接次数大于蓝牙设备BBB，但蓝牙设备AAA的连接时间小于蓝牙设备BBB的连接时间，赋值时，蓝牙设备AAA的第二权重值可以大于、小于也可以等于蓝牙设备BBB的第二权重值，具体可以根据需要设定。
当为蓝牙设备赋予了第一权重值与第二权重值以后，排序单元230根据第一权重值和第二权重值，对蓝牙设备进行排序。其中，在对蓝牙设备进行赋值时，扫描到的所有可连接的蓝牙设备，可以仅对于存在历史记录信息的蓝牙设备进行权重值的计算和赋值，对于扫描到的蓝牙设备，但是该蓝牙设备不存在历史记录信息，即该蓝牙设备可能从未与主设备进行过连接，可以不计算权重，或者是将该类设备赋予定值或是排列在最后，具体可以根据需要设置扫描到的且未有过历史连接记录的蓝牙设备。

例如，历史记录信息保存在文件名为bt_device.xml的XML文件中。
当主设备扫描到的设备有设备AAA、设备BBB、设备CCC和设备DDD时，根据历史记录信息，为扫描到的上述四个设备赋予权重值，根据历史记录信息，四个设备的第一权重值的从大到小为：设备AAA的第一权重值>设备CCC的第一权重值>设备BBB的第一权重值>设备DDD的第一权重值，因为设备AAA与主设备最近一次建立蓝牙的连接时间最近，设备DDD与主设备最近一次建立蓝牙的连接时间最远。例如将设备AAA、设备BBB、设备CCC和设备DDD的第一权重值可以分别设置为0.08、0.06、0.04、0.02。

若均为可接受主设备的蓝牙连接请求并与之建立蓝牙连接的蓝牙设备，控制单元320根据排序控制主设备自动连接蓝牙设备。例如设备AAA、设备BBB、设备CCC及设备DDD全部都为可以接受主设备的蓝牙连接请求并能够与主设备进行蓝牙连接的蓝牙设备，其排列顺序为：设备AAA>设备CCC>设备BBB >设备DDD，则在连接时，根据排列顺序先与设备AAA建立蓝牙连接，具体的，主设备向设备AAA发送蓝牙连接请求，若接收到蓝牙连接建立成功的消息，则确认主设备与设备AAA的蓝牙连接建立成功，若主设备与设备AAA连接失败，则向设备CCC发送蓝牙连接请求。
本实施例通过排序后获取蓝牙设备信息，并判断蓝牙设备是否均为可接收主设备的蓝牙连接请求并与之建立蓝牙连接的设备，若是，则根据排序控制主设备自动连接蓝牙设备，使得主设备在自动连接周围的蓝牙设备时，能够根据排列顺序进行连接，提高自动连接的速度。
基于本发明连接蓝牙设备的装置第三实施例，提出本发明连接蓝牙设备的装置第四实施例，本实施例中，上述控制模块30还包括：
删除单元，用于若所述蓝牙设备不是均为可接受所述主设备的蓝牙连接请求并与该主设备建立蓝牙连接的蓝牙设备，则从所述排序中删除无法接受所述主设备的蓝牙连接请求并与该主设备建立蓝牙连接的蓝牙设备。
本实施例中，若存在蓝牙设备不能接收主设备的蓝牙连接请求且不能与该主设备建立蓝牙连接的蓝牙设备时，删除单元将该蓝牙设备从排列顺序中删除。由于有些蓝牙设备无法接收蓝牙请求建立连接，只能通过主动发送蓝牙连接请求的方式建立蓝牙连接，因此若主动连接该设备，则经过一段等待时间会接收到连接失败的反馈，在这种情况下，自动连接蓝牙设备的时间变长了，因此在这里，将不能够接收主设备的蓝牙连接请求且不能与该主设备建立蓝牙连接的蓝牙设备进行删除，使得在蓝牙连接时提高蓝牙连接的效率。
通过此种方法也可以通过筛选仅连接想要连接的蓝牙类型，例如仅连接音频类型的蓝牙设备，若检测到鼠标类型的蓝牙设备，不进行连接。则在连接时判断蓝牙设备是否为预置的蓝牙类型，若是，则进行连接，若否，则在排序中删除该设备。
例如，当检测到的设备AAA、设备BBB、设备CCC的设备类型为24，设备DDD的设备类型为25，其中24类型表示该设备为音频，25类型表示该设备为鼠标，当希望仅连接音频设备时，将设备DDD从排序中删除，仅连接设备AAA、设备BBB和设备CCC，则连接时根据AAA>设备CCC>设备BBB的顺序进行自动连接。
本实施例通过当排序后的蓝牙设备中存在无法接收主设备的蓝牙连接请求或与该主设备建立蓝牙连接的蓝牙设备，则从排序中将该设备删除，此时主设备根据排列顺序自动连接蓝牙设备时，由于删除了无法连接的蓝牙设备，使得连接的时候减少了连接等待时间，提高了蓝牙连接的连接速度和效率。
基于本发明连接蓝牙设备的装置上述实施例，提出本发明连接蓝牙设备的装置第五实施例，本实施例中，本发明提出的连接蓝牙设备的装置还包括：
保存模块40，用于在所述主设备按所述排序自动连接所述蓝牙设备后，实时记录所述蓝牙设备与所述主设备之间蓝牙连接信息，并保存至所述历史记录信息，其中，所述蓝牙连接信息包括：所述蓝牙连接的连接时间、所述蓝牙连接的连接时长、以及所述蓝牙连接的连接次数。
本实施例中在主设备按排序自动连接蓝牙设备后，保存模块40实时记录连接信息并保存。具体的是在主设备与周围某一蓝牙设备建立蓝牙成功时，相关连接信息，将连接信息保存至历史记录信息，具体是按照历史记录信息的文件格式进行存储，例如历史记录信息保存在XML格式的文件中时，将连接信息以XML文件格式进行存储。
蓝牙连接信息包括，蓝牙连接的连接时间、蓝牙连接的连接时长以及蓝牙连接的连接次数。具体的，例如当设备BBB与主设备建立蓝牙连接成功时，将蓝牙连接信息更新至历史记录信息，当设备BBB与主设备建立蓝牙连接5分钟又断开后，获取其连接时间为15:34:01 31/09/2015，连接时长为300s，连接次数为在历史连接次数上累加，若之前连接次数为5，则更新后为6。
具体的，历史记录信息中设备BBB的连接信息在bt_device.xml文件中,更新为:
<device value = "1">
<bd_addr>00:00:00:00:17:DE:</bd_addr>
<device_name>BBB</device_name>
<class_of_device>24</class_of_device>
<count>5<count>
<last_timer>15:34:01 31/09/2015<last_timer>
<last_connect_time>300s< last_connect_time>
<last_time>1<last_time>
可以理解的是，蓝牙连接信息除了可以包括以上连接信息还可以在蓝牙设备更改了蓝牙设备名称时，再次保存该蓝牙设备的蓝牙名称等其他信息。
当历史记录信息根据最新的蓝牙连接情况进行更新后，主设备再次进行蓝牙连接时，可以根据最新的历史记录信息进行排序，从而进行自动连接。
本实施例通过在主设备按排列顺序自动连接蓝牙设备后，实时记录蓝牙设备与主设备之间蓝牙连接信息，并保存至历史记录信息中，使得历史记录信息根据最新的蓝牙连接情况进行更新，使得再次进行连接时，可以根据最新的历史记录信息进行排序，提高主设备蓝牙自动连接的速度。
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。
