D1s 使用 XR829 BT 配置 a2dp-source 出错

柚木鉉 LV 9

首先按照帖子《D1 开发板使用 XR829 mesh fw 出现 code(56) 错误，如何解决》：
https://bbs.aw-ol.com/topic/361/share/1 配置了蓝牙，输出

然后bt_test -i -p a2dp-source

stop bluetoothd and hciattach

估计是我什么配置的问题，麻烦大佬分析一下

看起来好像没开 dbus？

@whycan dbus肯定开了的，不开都跑不起来

@whycan 看着像dbus-daemon没起来，但是我没找到怎么启动

@whycan
dbus报错

改了一下conf

/etc/init.d/dbus restart

然后就好了
