Embodiment one
Fig. 2 is the flow diagram of bluetooth low energy device of embodiment of the present invention data transmission method.
Referring to Fig. 2, the executing subject of bluetooth low energy device data transmission method provided in an embodiment of the present invention is visitor
Family end.Bluetooth low energy device data transmission method of the embodiment of the present invention includes:
S101: the Universally Unique Identifier UUID of client acquisition server-side；The UUID corresponds to low-power consumption bluetooth data
At least two property attributes provided are serviced, by user according to low-power consumption bluetooth general-purpose attribute specification (Generic Attribute
Profile, referred to as: GATT agreement) definition.
Specifically, in a kind of low-power consumption bluetooth data service contextual model (profile), including a primary service sound
It is bright, for indicating the service content of the item data service.The low-power consumption bluetooth data service is defined in the primary service
One or more property attributes.The UUID is the mark that is defined in advance according to low-power consumption bluetooth GATT agreement of user, can be by
The server-side and client identification and inquiry, are the identifiers communicated between two bluetooth equipments.Each UUID corresponding one
Data transmission channel.Optionally, the server-side can also increase characteristic description for each data transmission channel, to describe
Characteristic and purposes of the data transmission channel etc..In the present embodiment, can be customized by the user the UUID with it is described low
The corresponding relationship of the property attribute of power consumption blue-teeth data.Such as: a UUID can be set and correspond to the low-power consumption bluetooth data
Two or more property attributes, described two or multifrequency nature attribute packet content can be corresponding by the UUID
Data transmission channel is transmitted；That is, the corresponding data transmission channel of the UUID support to send multifrequency nature attribute it is corresponding
Packet content.Alternatively, on the basis of previous embodiment, the UUID can have multiple, and the corresponding data of each UUID pass
Defeated channel can support the packet content of transmission multifrequency nature attribute, then the packet content of the multifrequency nature attribute can
To be transmitted by the corresponding data transmission channel of any one UUID.
S102: according to preset UUID in the UUID of the server-side and the client, the client and institute are determined
State the data transmission channel that server-side carries out data transmission.

The self-defining data package after crossing sequence is combined into complete data packet.
Specifically, wherein the origin identification is 1 byte, the data packet is indicated when the origin identification is 0x01
For first packet in complete data packet, the origin identification indicates that the data packet is the continuity of other data packets when being 0x00
Packet.The data type is 1 byte, and the different numerical value of the byte indicate that different data types, data need root when sending
According to different data types to the part assignment.The package identification fixes 1 byte.If the same big data packet point
It is transmitted for multiple small data packets, then uses identical package identification value, use different identification value between different data packet
It is transmitted.The data packet length is 2 bytes, and the long data packet angle value is used to indicate the total length of data packet, maximum
Support 64Kbyte.A total of 5 bytes in packet header, the packet header is superimposed on the front end of the packet content, the data
It is exactly the actual data packet content corresponding with the data type to be transmitted of the data packet that packet class, which is held,.
Bluetooth low energy device data transmission method provided in an embodiment of the present invention, by obtaining the general unique of server-side
Identification code UUID；According to preset UUID in the UUID of the server-side and the client, determine the client with it is described
The data transmission channel that server-side carries out data transmission；By the data transmission channel corresponding with the UUID, institute is received
At least one self-defining data packet of server-side transmission is stated, the packet content of the self-defining data packet corresponds to the low-power consumption
One of property attribute of blue-teeth data service.Using bluetooth low energy device transmission side data provided in an embodiment of the present invention
Method is defined by the corresponding UUID of property attribute to low-power consumption bluetooth data service, so that the corresponding number of a UUID
The packet content of the multiple property attribute can be supported to transmit according to channel, bluetooth equipment can be corresponding by the UUID
Data transmission channel transmits packet content corresponding with any one property attribute using the self-defining data packet, from
And the same data channel is made to can according to need a plurality of types of property attribute data of transmission, improve data transfer channel
Utilization rate saves system resource.
