Double-wireless Bluetooth communication network packet loss data processing method, device and system

Abstract

The invention discloses a double-wireless Bluetooth communication network packet loss data processing method, device and system, and the method comprises the steps: building a double-wireless Bluetooth communication network with Bluetooth sound source equipment and second Bluetooth equipment, wherein first Bluetooth equipment serves as network main equipment for controlling the communication flowof the double-wireless Bluetooth communication network; receiving an audio data packet sent by the Bluetooth sound source equipment through the first Bluetooth link, and during the period, monitoringthe audio data packet by the second Bluetooth equipment through the Bluetooth monitoring link; performing correction forwarding operation on the audio data packet which is wrongly received or wronglymonitored through a second Bluetooth link; and during the correction forwarding operation, pausing to send an audio data request instruction to the Bluetooth sound source device until the first Bluetooth device and the second Bluetooth device complete the correction forwarding operation. The correction forwarding operation is not interfered by the Bluetooth sound source equipment, and the correction forwarding communication quality and correction efficiency between the first Bluetooth equipment and the second Bluetooth equipment are improved.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a method, device and system for processing packet loss data in a dual wireless bluetooth communication network. Background technique [0002] In the application of dual wireless Bluetooth communication, such as dual wireless Bluetooth headsets, dual wireless Bluetooth speakers and other scenarios, three Bluetooth devices need to communicate through at least two Bluetooth links, thus forming a dual wireless Bluetooth device communication system. That is, the dual wireless bluetooth device communication system includes three bluetooth devices, one of which is a bluetooth audio source device (such as a mobile phone, a notebook computer, etc.), and the other two wireless bluetooth devices (such as a double wireless bluetooth headset, a double wireless bluetooth speaker Wait). Wherein, the Bluetooth playback device connected to the Bluetooth audio source device is usu...

AI Technical Summary

Problems solved by technology

Therefore, when performing data interaction (such as correction, forwarding data, etc.) Corrected communication quality between the first Bluetooth device 102' and the second Bluetooth device 103';

[0008] (2) The data interaction time between the first Bluetooth device 102' and the second Bluetooth device 103' is limited

[0009] Because in the dual wireless Bluetooth communication network, the Bluetooth audio source device 101' is the network master device to dominate the inter-network communication timing, the first Bluetooth device 102' and the second Bluetooth device 103' can only send data in the Bluetooth audio source device 101' Perform data interaction at idle time intervals outside the package, that is, the data interaction time between the first Bluetooth device 102' and the second Bluetooth device 103' is limited;

[0010] (3) Data cannot be exchanged continuously for a long time between the first Bluetooth device 102' and the second Bluetooth device 103'

Therefore, limited by the bluetooth communication protocol, the data interaction between the first bluetooth device 102' and the second bluetooth device 103' is affected by the network master device bluetooth audio source device 101', so it is impossible to carry out data interaction continuously for a long time. Data interaction can be performed across time slots, resulting in low data forwarding efficiency and affecting the communication quality between the first Bluetooth device 102' and the second Bluetooth device 103'
