日志显示,你的系统在尝试连接到一个特定的蓝牙设备(MAC地址为64:68:76:46:13:D0)时,多次遇到了“A2DP sink profile connect failed for [MAC]: Protocol not available”的错误。这通常表示尝试建立的蓝牙音频接收(A2DP sink)连接由于缺少相应的协议支持而失败。这个问题可能由以下几个原因造成: 蓝牙驱动或固件问...

Connect successfully to the AirPods (even works automatically whenever I open the case). After that the connection would be established automatically, however there's only HSP/HFP would be available. As soon as I switch the profile to A2DP (within KDEs bluetooth-settings), the output would get...

connectDATAPATHcommon>buffer);流程当然就,是做一socket。连接patch是data/misc/bluedroid/.a2dp_data , commonaudio_fd = skt_connect(A2DP_DATA_PATH, common->buffer_sz); 那后续 audio 传下来的数据只要写到common->audio_fd就可以了。 那关于 a2dp的数据通道的打开,这里就分析结束了。 接下来我们...
