具体地，蓝牙主设备和蓝牙从设备均安装有专有应用客户端并在应用客户端进行信息注册，从而服务器保存有蓝牙主设备和蓝牙从设备的注册信息，当蓝牙主设备与服务器连接时，蓝牙主设备的应用模块向服务器发送包括蓝牙从设备的标识信息的第一链接值查询信息，服务器依据保存的蓝牙主设备和蓝牙从设备的注册信息，并根据蓝牙从设备的标识信息确定蓝牙从设备是否为蓝牙主设备的相关设备。Specifically, both the Bluetooth master device and the Bluetooth slave device are installed with a proprietary application client and register information in the application client, so that the server saves the registration information of the Bluetooth master device and the Bluetooth slave device. When the Bluetooth master device is connected to the server, the application module of the Bluetooth master device sends a first link value query message including the identification information of the Bluetooth slave device to the server. The server determines whether the Bluetooth slave device is a related device of the Bluetooth master device based on the saved registration information of the Bluetooth master device and the Bluetooth slave device and the identification information of the Bluetooth slave device.
步骤S22，当蓝牙从设备为蓝牙主设备的相关设备时，蓝牙主设备的应用模块接收服务器发送的与蓝牙从设备的标识信息相对应的随机的第一链接值。Step S22: when the Bluetooth slave device is a related device of the Bluetooth master device, the application module of the Bluetooth master device receives a random first link value corresponding to the identification information of the Bluetooth slave device and sent by the server.
由此，蓝牙主设备的应用模块能够较为快速且方便的获取第一链接值，且由于蓝牙主设备的应用模块获取的为随机的第一链接值，便于蓝牙主设备和蓝牙从设备更为安全的进行数据传输。Therefore, the application module of the Bluetooth master device can obtain the first link value relatively quickly and conveniently, and because the application module of the Bluetooth master device obtains a random first link value, the Bluetooth master device and the Bluetooth slave device can perform data transmission more safely.
步骤S3，所述蓝牙主设备与所述蓝牙从设备建立物理链路连接，并将其标识信息发送给所述蓝牙从设备。Step S3: the Bluetooth master device establishes a physical link connection with the Bluetooth slave device, and sends its identification information to the Bluetooth slave device.

When the application module of the Bluetooth slave device sends the second link value query information including the identification information of the Bluetooth master device to the server, the server determines whether the Bluetooth master device is a related device of the Bluetooth slave device based on the saved registration information of the Bluetooth master device and the Bluetooth slave device and the identification information of the Bluetooth master device.
优选地，步骤S4中，在蓝牙从设备的应用模块向服务器发送第二链接值查询信息之前，还包括：Preferably, in step S4, before the application module of the Bluetooth slave device sends the second link value query information to the server, it also includes:

当蓝牙主设备为蓝牙从设备的可能相关设备时，蓝牙从设备的应用模块向服务器发送第二链接值查询信息。When the Bluetooth master device is a possible related device of the Bluetooth slave device, the application module of the Bluetooth slave device sends second link value query information to the server.
具体地，当标识信息为蓝牙地址时，蓝牙从设备的应用模块根据蓝牙主设备的蓝牙地址的前三个字节判断蓝牙主设备的生产厂商，并根据蓝牙从设备在应用客户端进行信息注册时保存的与其相关的蓝牙主设备的生产厂商信息，确定蓝牙主设备是否为蓝牙从设备的可能相关设备。Specifically, when the identification information is a Bluetooth address, the application module of the Bluetooth slave device determines the manufacturer of the Bluetooth master device based on the first three bytes of the Bluetooth address of the Bluetooth master device, and determines whether the Bluetooth master device is a possible related device of the Bluetooth slave device based on the manufacturer information of the Bluetooth master device related to the Bluetooth slave device saved when the Bluetooth slave device registers information on the application client.
蓝牙从设备的应用模块先根据蓝牙主设备的标识信息初步判断蓝牙主设备是否为蓝牙从设备的可能相关设备，当蓝牙主设备为蓝牙从设备的可能相关设备时，蓝牙从设备的应用模块才向服务器发送第二链接值查询信息，由此便于减小服务器的工作量，避免服务器过于繁忙。The application module of the Bluetooth slave device first preliminarily determines whether the Bluetooth master device is a possible related device of the Bluetooth slave device based on the identification information of the Bluetooth master device. When the Bluetooth master device is a possible related device of the Bluetooth slave device, the application module of the Bluetooth slave device sends the second link value query information to the server, thereby reducing the workload of the server and avoiding the server being too busy.
步骤S5，当所述蓝牙主设备为所述蓝牙从设备的相关设备时，所述蓝牙从设备的应用模块接收所述服务器发送的第二链接值，所述第一链接值与所述第二链接值相同。Step S5: when the Bluetooth master device is a related device of the Bluetooth slave device, the application module of the Bluetooth slave device receives a second link value sent by the server, and the first link value is the same as the second link value.
步骤S6，所述蓝牙主设备与所述蓝牙从设备分别根据第一链接值和第二链接值建立连接并进行数据传输。Step S6: the Bluetooth master device and the Bluetooth slave device establish a connection and perform data transmission according to the first link value and the second link value respectively.

The Bluetooth master device and the Bluetooth slave device establish a connection and perform data transmission according to the first link key and the second link key respectively.
具体地，蓝牙主设备的应用模块可以根据第一链接密钥计算值通过哈希算法或其它算法得到第一链接密钥，蓝牙从设备的应用模块根据第二链接密钥计算值通过与计算得到第一链接密钥相同的算法得到第二链接密钥。Specifically, the application module of the Bluetooth master device can obtain the first link key through a hash algorithm or other algorithms based on the first link key calculation value, and the application module of the Bluetooth slave device can obtain the second link key through the same algorithm as the first link key calculation value based on the second link key calculation value.
优选地，当蓝牙主设备与服务器连接时，第一链接值为第一链接密钥，第二链接值为第二链接密钥。Preferably, when the Bluetooth master device is connected to the server, the first link value is the first link key, and the second link value is the second link key.
具体地，蓝牙主设备与服务器连接时，蓝牙主设备的应用模块接收服务器发送的随机的第一链接密钥，蓝牙从设备的应用模块接收服务器发送的随机的第二链接密钥，蓝牙主设备与蓝牙从设备可以直接分别根据第一链接密钥和第二链接密钥建立连接并进行数据传输，由此通过蓝牙主设备和蓝牙从设备的应用模块分别直接从服务器获取第一链接密钥和第二链接密钥，而避免了双方在本地计算第一链接密钥和第二链接密钥，进一步的提高了蓝牙主设备与所述蓝牙从设备的连接速度。Specifically, when the Bluetooth master device is connected to the server, the application module of the Bluetooth master device receives the random first link key sent by the server, and the application module of the Bluetooth slave device receives the random second link key sent by the server. The Bluetooth master device and the Bluetooth slave device can directly establish a connection and transmit data according to the first link key and the second link key, respectively. In this way, the first link key and the second link key are directly obtained from the server through the application modules of the Bluetooth master device and the Bluetooth slave device, respectively, which avoids the need for both parties to locally calculate the first link key and the second link key, thereby further improving the connection speed between the Bluetooth master device and the Bluetooth slave device.
具体地，可以在蓝牙主设备每次开机时，例如，当蓝牙主设备为车载蓝牙时，在车辆每次点火开机时，当蓝牙主设备与服务器连接时，蓝牙主设备的应用模块获取服务器发送的与蓝牙从设备的标识信息相对应的新的随机的第一链接值，蓝牙从设备的应用模块获取服务器发送的新的第二链接值，以便于蓝牙主设备与蓝牙从设备分别根据新的第一链接值和第二链接值建立连接并进行数据传输，以增强蓝牙主设备与蓝牙从设备数据传输的安全性。Specifically, each time the Bluetooth master device is turned on, for example, when the Bluetooth master device is a vehicle-mounted Bluetooth, each time the vehicle is ignited and turned on, when the Bluetooth master device is connected to the server, the application module of the Bluetooth master device obtains a new random first link value sent by the server corresponding to the identification information of the Bluetooth slave device, and the application module of the Bluetooth slave device obtains a new second link value sent by the server, so that the Bluetooth master device and the Bluetooth slave device can establish a connection and perform data transmission according to the new first link value and the second link value respectively, so as to enhance the security of data transmission between the Bluetooth master device and the Bluetooth slave device.
优选地，当蓝牙主设备与服务器断开连接时，第一链接值为第一链接密钥计算值，第二链接值为第二链接密钥计算值，Preferably, when the Bluetooth master device is disconnected from the server, the first link value is the first link key calculation value, the second link value is the second link key calculation value,

The Bluetooth master device and the Bluetooth slave device establish a connection and perform data transmission according to the first link key and the second link key respectively.
具体地，蓝牙主设备与服务器断开连接时，根据蓝牙主设备在应用客户端进行信息注册时保存的与其相关的蓝牙从设备的标识信息，确定蓝牙从设备是否为蓝牙主设备的相关设备，当蓝牙从设备为蓝牙主设备的相关设备时，蓝牙主设备的应用模块根据蓝牙从设备的标识信息与链接密钥计算值的对应关系获取的固定的第一链接密钥计算值，且当蓝牙主设备为蓝牙从设备的相关设备时，由于服务器中储存有与蓝牙主设备的应用模块中储存的相同的蓝牙从设备的标识信息与链接密钥计算值的对应关系，蓝牙从设备的应用模块获取服务器发送的与固定的第一链接密钥计算值相同的第二链接密钥计算值。Specifically, when the Bluetooth master device is disconnected from the server, it is determined whether the Bluetooth slave device is a related device of the Bluetooth master device based on the identification information of the Bluetooth slave device related to it that is saved by the Bluetooth master device when registering information on the application client. When the Bluetooth slave device is a related device of the Bluetooth master device, the application module of the Bluetooth master device obtains a fixed first link key calculation value based on the correspondence between the identification information of the Bluetooth slave device and the link key calculation value. When the Bluetooth master device is a related device of the Bluetooth slave device, since the server stores the same correspondence between the identification information of the Bluetooth slave device and the link key calculation value as that stored in the application module of the Bluetooth master device, the application module of the Bluetooth slave device obtains the second link key calculation value sent by the server that is the same as the fixed first link key calculation value.
由此，当蓝牙主设备与服务器断开连接时，蓝牙主设备与蓝牙从设备也能够较为便利且快速的进行连接。Therefore, when the Bluetooth master device is disconnected from the server, the Bluetooth master device and the Bluetooth slave device can also be connected more conveniently and quickly.
通过判断蓝牙从设备是否为蓝牙主设备的相关设备，当蓝牙从设备为蓝牙主设备的相关设备时蓝牙主设备的应用模块获取与蓝牙从设备的标识信息相对应的第一链接值，并通过服务器确定蓝牙主设备是否为蓝牙从设备的相关设备，当蓝牙主设备为蓝牙从设备的相关设备时蓝牙从设备的应用模块接收服务器发送的第二链接值，本发明实施例的蓝牙设备的连接方法，避免了计算能力较弱的双方蓝牙模块通过多次空中交互多次握手的方式才产生链接密钥，不仅加快了链接秘钥的计算过程而且无需人工操作即可完成配对流程，提高了蓝牙设备首次连接的速度。By judging whether the Bluetooth slave device is a related device of the Bluetooth master device, when the Bluetooth slave device is a related device of the Bluetooth master device, the application module of the Bluetooth master device obtains a first link value corresponding to the identification information of the Bluetooth slave device, and determines through a server whether the Bluetooth master device is a related device of the Bluetooth slave device, and when the Bluetooth master device is a related device of the Bluetooth slave device, the application module of the Bluetooth slave device receives a second link value sent by the server. The connection method of the Bluetooth device in the embodiment of the present invention avoids the situation that the Bluetooth modules of both parties with weak computing power generate link keys through multiple air interactions and multiple handshakes, which not only speeds up the calculation process of the link key but also completes the pairing process without manual operation, thereby improving the speed of the first connection of the Bluetooth device.
