Description
Technical field
The present invention relates to a kind of methods of bluetooth BLE transmission speed on raising IOS terminal device.
Background technique
With bluetooth BLE(Bluetooth Low Energy bluetooth low energy consumption technologies) be widely used, have at present more next
Carried out data transmission between more electronic products by bluetooth, and bluetooth BLE is widely used with low power consumption characteristic.Bluetooth
BLE can realize being continuously connected between mobile intelligent terminal and periphery accessory, be the extremely low short-distance wireless communication technology of power consumption,
And with the development of time, IOS terminal device (such as mac, iphone, ipad etc.) is connect by bluetooth BLE with peripheral hardware more next
It is more.However, IOS system limits bluetooth BLE transmission rate, the bluetooth BLE minimum time interval of IOS terminal device is big
In 20ms, a transmission time most multipotency reaches 5 to 7 packets, and each most 20 bytes of packet, transmission rate is about 5kB/s.?
In practical application, if to transmit larger data, it will lead to that transmission time is too long, and the effect is relatively poor for user experience.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the shortcomings of above-mentioned background technique, provide a kind of raising IOS terminal
The method of bluetooth BLE transmission speed in equipment is conducive to the transmission of larger file, improves Bluetooth transmission amount and transmission speed.
The technical solution used to solve the technical problems of the present invention is that bluetooth BLE is sent on a kind of raising IOS terminal device
The method of speed, comprising the following steps:
(1) it is arranged in bluetooth peripheral hardwareNA bluetooth BLE unit module,N Round numbers,N>=2, by the main place of bluetooth peripheral hardware
Reason device is connected with each bluetooth BLE unit module respectively by serial ports；By each bluetooth BLE of IOS terminal device and bluetooth peripheral hardware
Unit module carries out pairing connection；
(2) in IOS terminal device, the data transmitted will be needed to be divided intoNA data block: data block 1, data block 2, data block
3 ... data blocksN- 1, data blockN, each data block is transferred to bluetooth peripheral hardware by corresponding bluetooth BLE unit module；Each data block
Cross-circulation is sent, and the partial data of data block 1 carries out after once sending, every
The partial data of data block 2 is sent, then
Every
Send data block 3 partial data ... again every
Send data blockN- 1 partial data, then every
It sends
Data blockNPartial data, then every
The partial data of data block 1 is sent, with this poll, until each data block is all sent out
It send and finishes；
(3) after bluetooth peripheral hardware receives each data block, the primary processor of bluetooth peripheral hardware merges each data block, restores
Original data out.
Further, in step (2), the IOS terminal device is mac or iphone or ipad.
Compared with prior art, advantages of the present invention is as follows: the transmission speed of bluetooth BLE can be improved, while be conducive to compared with
The transmission of big file, improves Bluetooth transmission amount, to improve user experience.
Detailed description of the invention
Fig. 1 is the hardware device schematic diagram of the embodiment of the present invention.
Fig. 2 is the functional block diagram of the embodiment of the present invention.
Fig. 3 is the data transmission waveform diagram that bluetooth BLE data send interval 20ms.
Fig. 4 is that the data of the embodiment of the present invention send waveform diagram.
Specific embodiment
With reference to the accompanying drawing and specific embodiment present invention is further described in detail.
In the agreement of bluetooth BLE, transmission intercal can be less than 10ms, and the method for the present invention application bluetooth BLE can be connected simultaneously
Two or more bluetooth BLE unit modules are arranged on bluetooth peripheral hardware and receive data for the characteristic of multiple equipment.Lower example is to set two
Illustrate for bluetooth BLE unit module, bluetooth BLE unit module is bluetooth BLE unit module chip.
Referring to Fig.1, Fig. 2, the present embodiment the following steps are included:
(1) bluetooth BLE unit module A and bluetooth BLE unit module B is set in bluetooth peripheral hardware, by the master of bluetooth peripheral hardware
Processor is connected with bluetooth BLE unit module A and bluetooth BLE unit module B respectively by serial ports；By IOS terminal device and indigo plant
The bluetooth BLE unit module A of tooth peripheral hardware carries out pairing with bluetooth BLE unit module B and connects；
(2) in IOS terminal device, the data transmitted will be needed to be divided into two data blocks: data block A and data block B, data
Block A is transferred to bluetooth peripheral hardware by bluetooth BLE unit module A, and data block B is transferred to outside bluetooth by bluetooth BLE unit module B
If；Data block A and data block B cross-circulation are sent, and the partial data A1 of data block A is carried out after once sending, and are sent every 10ms
The partial data B1 of data block B, then the partial data A2 of data block A is sent every 10ms, with this poll, until data block A sum number
It is all sent according to block B；
(3) after bluetooth peripheral hardware receives data block A and data block B, the primary processor of bluetooth peripheral hardware by two data blocks into
Row merges, and restores data original out.
IOS terminal device (mac, iphone, ipad etc.) sends data and sends once by the every 20ms of bluetooth BLE, big every time
The arrangement of about several crossed joints is transmitted, referring to Fig. 3, if distributing rear 20ms by data block A retransmits data block B, and total speed
Degree is not improved.Referring to Fig. 4, the partial data A1 of data block A is carried out after once sending in step (2), sends number every 10ms
The partial data A2 of data block A is sent according to the partial data B1 of block B, then every 10ms, with this poll, in this way to IOS terminal device
For, it is all the interval the 20ms transmission by standard no matter for bluetooth BLE unit module A or bluetooth BLE unit module B, and
Real data transmission rate is then data block A and data block B is combined transmission rate, is divided into 10ms between data transmission time,
Rate can be improved one times, and then improve the transmission speed of bluetooth BLE, while being conducive to the transmission of larger file, improves bluetooth and passes
Throughput rate, to improve user experience.
Those skilled in the art can carry out various modifications to the present invention and modification, if these modifications and variations are at this
Within the scope of invention claim and its equivalent technologies, then these modifications and variations are also within protection scope of the present invention.
The prior art that the content being not described in detail in specification is known to the skilled person.
