Communication method and device thereof

Abstract

The invention discloses a communication method and a device thereof, and the specific implementation scheme is that the method comprises the steps: obtaining a receiving result of first audio information in predefined time of a communication period, wherein the first audio information is sent by playing equipment, and the first audio information occupies a first time period in the predefined time;generating control information according to the receiving result, and determining that the control information occupies a second time period in predefined time; and sending the control information toa first receiver so that the first receiver generates a control instruction according to the control information, and wherein the control instruction is used for controlling the playing device to send the second audio information. The control information can be sent without determining odd time slots or even time slots, and the control information does not occupy new time slots, so that resourcesare effectively saved. Therefore, the transmission efficiency of the control information between the two receivers is improved, the two receivers are in a better synchronous state, and the communication efficiency between the playing device and the two receivers is further improved.

Description

Technical field [0001] This application relates to the field of wireless communication, especially to the field of Bluetooth communication. Background technique [0002] Bluetooth communication technology is a wireless communication technology, which is usually applied between two devices. In the use scenario of a Bluetooth wireless headset, it is necessary to communicate between multiple wirelessly connected devices (for example, two earpieces and a mobile device). For example, a mobile device needs to send audio information to the left earpiece and the right earpiece at the same time, and the left earpiece and the right earpiece are connected wirelessly. However, in the communication process of the existing Bluetooth wireless headset, the transmission of all information complies with a slot mechanism, and only one RF packet can be sent or received in each slot, and for different types of equipment, For example, the master device or the slave device can only send radio frequen...

Problems solved by technology

However, in the communication process of the existing Bluetooth wireless headset, all information is sent in accordance with a time slot (Slot) mechanism, and only one radio frequency packet can be sent or received in each time slot, and for different types of devices, For example, the master (Master) device or the slave (Slave) device can only send radio frequency packets on odd or even time slots, resulting in the state exchange between the two earphones at least needing to occupy more than two time slots, causing the entire mobile device The utilization rate of the communication channel between the two earphones is low, the information transmission efficiency is low, and the information transmission time is long, which will also cause the left earpiece and the right earpiece to be more prone to out-of-sync situations.
