Abstract

本申请公开了一种音频数据的同步方法及设备，涉及短距离通信领域，在手机与多个蓝牙设备建立了无线连接时，实现了多个蓝牙设备之间音频数据的播放级同步。电子设备通过CIG的第一CIS，向与该电子设备建立无线连接的第一耳塞发送数据包，通过CIG的第二CIS，向与该电子设备建立无线连接的第二耳塞发送数据包；该数据包包括：音频数据，数据包的音频时间戳，以及初始蓝牙时间戳，初始蓝牙时间戳为电子设备与第一耳塞建立第一CIS，与第二耳塞建立第二CIS后传输的第一个数据包的蓝牙时间戳；音频时间戳和初始蓝牙时间戳用于第一耳塞和第二耳塞确定CIG播放点，CIG播放点是第一耳塞和第二耳塞播放音频数据的时间点。
