Background
BLE refers to Bluetooth Low Energy (Bluetooth Low Energy technology), and can implement Low-power data transmission between Bluetooth devices. A large number of devices currently support BLE functionality, such as cell phones and some smart accessories. However, the data transmission speed of BLE is not very high, mainly due to two reasons, one is that the maximum packet length used by many devices by default is 20 bytes, and the other is that the sender needs to wait for the receiver to reply after sending a data packet before sending the next packet.

Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
The length of a data packet in the existing BLE (default 20 bytes) is that after a sender sends a data packet to a receiver, the sender needs to wait for the receiver to reply before sending the next data packet, that is, a question-and-answer mode is adopted.
The invention adopts a mode of combining the increase of the length of the data packet (the byte number of the data is more than 20 bytes) and a continuous sending mechanism of the data packet to replace a data packet transmission mechanism in the prior BLE technology. On one hand, the amount of data transmitted by one data packet is increased; on the other hand, the sender can continuously send a plurality of data packets and then receive the reply of the data receiver, thereby reducing the frequency of waiting for the reply of the data receiver and saving the time of waiting for the reply of the data receiver. According to the invention, a data transmission speed higher than that of the existing BLE data transmission speed is obtained through a new data transmission mechanism.
Fig. 1 shows an embodiment of a method for increasing a transmission speed of bluetooth low energy according to the present invention, in which the method mainly includes the following steps:
s1 is a step of establishing a communication connection between the master device and the Peripheral device, where the master device (Controller) and the Peripheral device (Peripheral) in the bluetooth protocol establish a communication connection through a generic attribute Profile (GATT) service by using a bluetooth low energy technology. In one embodiment of the present invention, the master device may be a smartphone, a tablet, a Personal Computer (PC), or the like. The peripheral device may be a sphygmomanometer, a thermometer, a bracelet, a bluetooth remote control, etc.
S2 is a step of negotiating the maximum transmission packet length between the master device and the peripheral device, and the peripheral device sends a request for negotiating the maximum packet length to the master device. The maximum packet length is the number of bytes of the data packet sent by the master device, and preferably, the negotiated maximum number of bytes of the packet length is greater than 20. The main control device determines the negotiated maximum packet length after receiving the request of the peripheral device, and then feeds back the negotiated maximum packet length to the peripheral device, thereby providing technical support for subsequent data transmission.
S3 is a step of negotiating, by the main control device and the peripheral device, the number of consecutively transmitted data packets, where the peripheral device determines the number of data packets that can be consecutively received from the main control device, and then transmits, to the main control device, the number of data packets that the main control device is allowed to consecutively transmit. Preferably, the number of data packets continuously transmitted by the master device is greater than 1.
S4 is a step of parsing and packetizing data transmitted by the master device, where the master device parses and packetizes the transmitted data into data packets according to the maximum packet length negotiated with the peripheral device, and the number of bytes of each data packet is greater than 20.
S5 is a step of data transmission between the host and the peripheral, where the host transmits the disassembled and divided data packets in S4 to the peripheral according to the number of the data packets to be transmitted continuously. When the number of data packets received by the peripheral device is equal to the number of data packets continuously transmitted by the main control device, the main control device temporarily stops transmitting the data packets. The peripheral equipment sends a new requirement for the number of data packets which are allowed to be continuously sent by the main control equipment to the main control equipment, the main control equipment sends data according to the new requirement for the number of the data packets which are continuously sent, and a cyclic data transmission mode is formed according to the negotiation mode until the data in the main control equipment are completely sent to the peripheral equipment.
The method for increasing the transmission speed of bluetooth low energy according to the present invention is further described in an embodiment.
A smart phone (command device) transmits a segment of data containing 10,000 bytes to a bluetooth bracelet (peripheral device). The transmission of this piece of data in the manner of the invention requires the following steps:
and establishing communication connection, wherein the smart phone and the Bluetooth bracelet establish communication connection through a GATT service by adopting a low-power Bluetooth technology.
And negotiating the maximum transmission packet length, wherein the Bluetooth bracelet sends a maximum packet length negotiation request to the smart phone. For example, the maximum negotiated packet length byte number is 50. The smart phone determines that the negotiated maximum packet length is 50 after receiving the request of the Bluetooth bracelet, and then feeds back the negotiated maximum packet length to the Bluetooth bracelet.
And negotiating the number of the continuously transmitted data packets, wherein the smart phone determines the number of the continuously transmitted data packets, for example, the bluetooth bracelet can continuously receive 50 data packets. The bluetooth bracelet then transmits to the smartphone a number of data packets (50) requirement that the smartphone is allowed to continuously send.
And (3) disassembling and subpackaging transmission data, and disassembling and dividing the transmitted data into 200 data packets by the smart phone according to the maximum packet length (50) negotiated with the Bluetooth bracelet.
And a data transmission step, wherein the smart phone transmits the disassembled and divided 200 data packets to the Bluetooth bracelet according to the number (50) of the continuously transmitted data packets. When the number of the data packets received by the Bluetooth bracelet is equal to 50, the smart phone temporarily stops sending the data packets. The Bluetooth bracelet transmits a new data packet number requirement (for example, still 50) allowing the smart phone to continuously transmit to the smart phone, the smart phone transmits data according to the new data packet number requirement (still 50) continuously transmitted, and a cyclic data transmission mode is formed according to the negotiation mode until 10,000 bytes of data in the smart phone are completely transmitted to the Bluetooth bracelet.
In the above example, the smart phone needs to receive the bluetooth bracelet 4 times to allow the smart phone to continuously send the data packet number requirement (i.e. send 4 replies to the smart phone) to complete the data transmission of 10,000 bytes. If data transmission is carried out in the prior art, the smart phone needs to send 500 data packets, and the reply sent to the smart phone by the Bluetooth bracelet needs 500 times, which is obviously higher than the 4 replies in the invention.
The invention adopts the mode of combining the data packet length (the byte number of the data is more than 20 bytes) and the continuous data packet sending mechanism to transmit the data, reduces the frequency of waiting for the reply of the data receiver and saves the time of waiting for the reply of the data receiver.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
