[0106] Further, refer to Figure 7 , Figure 7 It is a schematic diagram of the functional modules of the second embodiment of the Bluetooth audio transmission adjustment device of the present invention. Based on the first embodiment of the Bluetooth audio transmission adjustment device of the present invention, the device may further include:

[0107] The second adjustment module 50 is configured to adjust the current Bluetooth audio transmission rate of the terminal according to the curve relationship between the preset Bluetooth audio transmission rate and the packet loss rate of the current Bluetooth audio transmission of the terminal.

[0108] During Bluetooth audio transmission, in addition to the Bluetooth transmission power, the Bluetooth transmission rate will also affect the effective transmission distance of Bluetooth transmission. When other conditions are the same, the faster the Bluetooth transmission rate, the more channels the transmission process will occupy....

Abstract

The invention discloses a Bluetooth audio transmission adjustment method. The method comprises the steps of obtaining a current Bluetooth audio transmission packet loss rate of a terminal; judging whether the current Bluetooth audio transmission packet loss rate is greater than or equal to a preset packet loss rate threshold value or not; if the current Bluetooth audio transmission packet loss rate is greater than or equal to the preset packet loss rate threshold value, calculating Bluetooth transmitting power corresponding to the current Bluetooth audio transmission packet loss rate according to a preset algorithm; and adjusting the current Bluetooth transmitting power of the terminal according to a calculation result. The invention also discloses a Bluetooth audio transmission adjustment device. According to the method and the device, the technical problem of audio delay resulting from packet loss in the Bluetooth audio data transmission process can be solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a Bluetooth audio transmission adjustment method and device. Background technique [0002] As a short-distance communication method, Bluetooth is widely used in the communication of various terminal devices (such as smart TVs, smart phones, Bluetooth headsets, Bluetooth speakers, etc.). Among them, Bluetooth audio transmission is based on the A2DP protocol (Advanced Audio Distribution Profile, Bluetooth audio transmission model protocol), and Bluetooth headsets, speakers, etc. transmit audio data streams through this protocol. [0003] In the Bluetooth communication process, the packet loss rate indicates the ratio of the number of lost data packets to the sent data group during data transmission. Usually, the empirical packet loss rate value is lower than one ten thousandth, and the data transmission is very smooth. However, the A2DP protocol has strict real-time requirem...
