Embodiment Construction

[0074] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0075] see Figures 1 to 5 , this embodiment provides a Bluetooth low energy communication method for communication between a first Bluetooth device and a second Bluetooth device. Common Bluetooth devices can be devices or accessories with Bluetooth communication modules such as earphones, mobile phones, tablets, notebook computers, and POS machines. Since this embodiment is applied to Bluetooth low power consumption, the Bluetooth device should support Bluetooth low power consumption. The bluetooth device can be the first bluetooth device or the second bluetooth device in the bluetooth low energy communication, and in this embodiment, the first bluetooth device is used to send data packets. According to the bluetooth communication p...

Abstract

The invention provides a method of Bluetooth low energy communication, Bluetooth devices and a system. The method comprises the following steps that: a first Bluetooth device detects current signal strength values of a second Bluetooth device, optimized sending rate values are selected according to corresponding relationship between the pre-stored signal strength values and the optimized sending rate values, and the optimized sending rate values are utilized to send a data packet. The different optimized sending rate values are selected according to the different signal strength values so as to send the data packet, so that the conditions that when the signal strength value is too strong, the data packet is sent at the lower speed to cause waste of communication resources and long consumption time can be avoided, meanwhile, the conditions that when the signal strength value is too weak, the data packet is sent at the higher speed to cause loss of the data packet and normal communication cannot be performed to decrease the communication speed finally can be avoided.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a bluetooth low power consumption communication method, a bluetooth device and a system. Background technique [0002] Bluetooth Low Energy (Bluetooth Low Energy, referred to as BLE) technology is a low-cost, short-range, interoperable and robust wireless technology, which is a key function of Bluetooth4. band. It was designed from the ground up as an Ultra Low Power (ULP) wireless technology. It enables many intelligent means to minimize power consumption. [0003] Bluetooth low energy technology uses a variable connection time interval, which can be set from a few milliseconds to a few seconds depending on the specific application. In addition, because BLE technology uses a very fast connection method, it can be in a "non-connected" state (to save energy) at ordinary times. The link may be shut down for a short period of time. [0004] The mode of operation...
