Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0036] Such as figure 1 As shown, the adaptive Bluetooth transmission method based on traffic awareness in this embodiment includes: S1. Acquiring the data traffic of the Bluetooth device at the next moment and the response delay at the next moment; S2. According to the data traffic at the next moment and the next Response delay at one moment, through the preset connection parameter model, determine the connection parameters of the Bluetooth device that meets the data flow at the next moment and the response delay at the next moment, and has the smallest power; S3. Configure with connection parameters Bluetooth devices for data transmission.

[0037] In this embodiment, the data flow at the next moment in step S1 is obtained by obtaining the historical data flo...

Abstract

The invention discloses an adaptive Bluetooth transmission method based on flow perception. The method comprises the following steps: S1, obtaining data flow of a Bluetooth device at a next moment and a response delay of the same at the next moment; S2, determining a connection parameter of the Bluetooth device satisfying the demands of the data flow at the next moment and the response delay at the at the next moment and having the minim power through a preset connection parameter model according to the data flow at the next moment and the response delay at the at the next moment; and S3, configuring the Bluetooth device through the connection parameter to perform data transmission. The adaptive Bluetooth transmission method disclosed by the invention has the advantages of not only meeting the requirements of the network throughput and the delay of the Bluetooth device, but also effectively reducing the communication power consumption of the Bluetooth device, and being simple in algorithm and high in response speed.

Description

technical field [0001] The invention relates to the technical field of bluetooth data transmission, in particular to an adaptive bluetooth transmission method based on flow perception. Background technique [0002] Bluetooth Low Energy, BLE (Bluetooth Low Energy, Bluetooth Low Energy) is the core specification of Bluetooth 4.0. The biggest feature of this technology is that it has ultra-low operating power consumption and standby power consumption. Compared with traditional Bluetooth, the power consumption is reduced by 90%. It can be applied to wireless solutions that have strict requirements on cost and power consumption, and has been widely used in smart homes, health and medical electronics, automotive electronics, smart wearable devices, and various Internet of Things applications, etc. [0003] Two basic configuration files, GAP and GATT, are defined in the BLE specification. The GAP layer in the protocol is responsible for device access modes and processes, including...
