Bluetooth data transfer method provided in an embodiment of the present invention is by obtaining synchronization link on current device first
All synchronization links that topological structure currently connects, and the synchronization link or the first broadcast communication data packet are mapped to
It is on preset time axis, i.e., unified by being carried out by main equipment, from the clock of equipment and each link, precisely determine free timeslot
And the second synchronization link, the second broadcast communication data packet are allocated, and then avoided between synchronization link, broadcast communication again
Conflict, realize the high efficiency of transmission of blue-teeth data.
Wherein, due to the clock (clock) in Bluetooth link (links) be divided into main equipment clock (master clock) and
From equipment clock (slave clock), the clock of each links may be different from, but the basic time piece of each clock
It is all with time slot (frame:1250us) for unit.Therefore, the present embodiment the method is in order to accurately same for second
Link or the second broadcast communication reservation distribution time slot frame are walked, therefore, it is necessary first to accurately count the logical of current device
The time slot fallen by the reservation of other synchronization links (synchronous links) on time shaft where letter link link
Frames, and free timeslot frame is found out to new synchronous link or the second broadcast communication.
Therefore, the present embodiment the method first looks at and obtains the topological structure of synchronization link on current device, that is, works as
Preceding existing synchronous links, and the time slot by the synchronization link on current device on respective clock time shaft
Frame occupancy situation is mapped on the corresponding preset time axis of desired clock, obtains what a time slot frame reservation occupied
Timing mapping table (base bitmap table), and accurately distributed to according to the Time Slot Occupancy situation after mapping on preset time axis
New synchronous link or the second broadcast communication, so effectively avoid between each synchronization link and synchronization link with
Conflict between broadcasting link.
Optionally, as shown in Fig. 2, it is described first synchronization link or the first broadcast communication data packet are mapped in it is pre-
If including: on time shaft
The gap information of S121, the gap information for obtaining the first synchronization link or the first broadcast communication data packet；
S122, it is incited somebody to action according to the gap information of first synchronization link or the gap information of the first broadcast communication data packet
First synchronization link or the first broadcast communication data packet are mapped on preset time axis.
For example, described believe according to the gap information of first synchronization link or the time slot of the first broadcast communication data packet
First synchronization link or the first broadcast communication data packet are mapped on preset time axis by breath can include:
When it is consistent that preset time axis, which corresponds to clock clock setting corresponding with the first broadcast communication, then according to each synchronous chain
Corresponding synchronization link is mapped on preset time axis by the gap information on road；
When it is inconsistent that preset time axis, which corresponds to clock clock setting corresponding with the first broadcast communication, then according to each synchronization
Corresponding synchronization link and the first broadcast communication are mapped in by the gap information of link and the gap information of the first broadcast communication respectively
On preset time axis.
Optionally, the gap information according to first synchronization link or the first broadcast communication data packet when
After first synchronization link or the first broadcast communication data packet are mapped on preset time axis by gap information, the method
Further include:
S123, will additionally disappear corresponding to the mapping process of first synchronization link or the first broadcast communication data packet
Time-consuming gap is mapped on the preset time axis.
Specifically, in order to more accurately obtain timing mapping table in the present embodiment, therefore, side described in the present embodiment
Method is and clear and accurate when obtaining existing link also by the time consumed in mapping process also correspondence mappings to preset time axis
The case where gap occupies, such as: as shown in figure 3, two links present in the topological structure of the first synchronization link on current device,
Respectively the first link and the second link, and the third link to be newly inserted into is needed to reserve frame.Wherein, the second link and
The clock of third link is identical, but with the first link difference, the frame occupancy situation of the second link and third link is mapped
Onto the clock time shaft of third link, a timing mapping table is obtained, i.e., in this example by the clock time of third link
Axis is as preset time axis.

It sets.
Optionally, described according to the occupied information and the second synchronization link or occupied information and the second broadcast communication
The gap information of data packet determines that the second synchronization link of transmission or the second broadcast communication data packet are corresponding on preset time axis
Before time location, the method also includes:
According to the occupied information of the preset time axis after mapping and the second synchronization link or the preset time after mapping
The gap information of the occupied information of axis and the second broadcast communication data packet judges that the free time position of the preset time axis is
It is no to be large enough to hold second synchronization link or the second broadcast communication data packet；
When free time position is large enough to hold, then directly determines and send the second synchronization link or the second broadcast communication number
According to packet on preset time axis corresponding time location；
When free time position can not accommodate, then the second synchronization link or the are sent according to pre-set priority sequence
Two broadcast communication data packets corresponding time location on preset time axis.
Specifically, as shown in figure 4, timing mapping of the present embodiment the method on the synchronization link for obtaining current device
Table then can determine reasonable time location according to time slot frame occupancy situation on timing mapping table, by new business (i.e. second
Synchronization link, the second broadcast communication) it is inserted into.In the case where more crowded, or to future key business such as voice
Synchronous link (SCO/eSCO) etc. make it is reserved,
Meanwhile this implementation the method is when time location is large enough to hold, then by adjust parameter preset (such as: Delta
Parameter) by the second synchronization link or the second broadcast communication data packet sending time position adjust to it is identified enough idle when
Between position；When time location can not accommodate, the present embodiment the method is also by using transmitted by preset strategy determination
Time location, so that the quality of the Bluetooth communication is optimized.Such as: preset strategy can be true by parameter priority sequence
Make optimal sending time position, wherein it is long that the priority that parameter priority may be configured as instantaneous number is higher than link session
It spends (i.e. slot length)；In addition, the present embodiment the method can not avoid conflicting by the adjustment of parameter preset, finally lead to
It crosses link priority sequence to be adjusted, guarantees the session normal communication of link.
For example, as described in Figure 4, when time location is large enough to hold, parameter=3 Delta will be adjusted, to new
The time slot frame scheme that synchronous link service appointment goes out is best, is obtaining (the i.e. session time of most instantaneous numbers
Number) in the case where, expected window (window) can also be got every time.
