【M401A】CoreELEC初步小试，毫无难度的安装和xue微折腾的蓝牙

M401A刷好hassio_supervisor后没有加入/run/dbus:/run/dbus:ro，后续怎么添加蓝牙进去？

你就参考armbian里的方法试试吧，原理一样，操作gpio。

我对coreelec不熟，最近也没办法测试。

通过安装插件，coreelec可以使用gpioset了，但发现了新问题。在armbian和coreelec里芯片组是反着的。并且GPIO数量差了一个。在coreelec无法操作82 GPIO。麻烦X大再给指点一下
这是armbian里的GPIO 信息

麻烦X大再给看一下，感觉离成功应该不远了。

EmuELEC 是基于 CoreELEC 弄出来的，想知道到是不是可以直接抄作业？但是我打开根目录只看到kernel.img和dtb.img两个img，另外还有几个文件夹， lib/firmware/rtl_bt 这个目录在哪里呢？

我感觉得重新编译dtb。

按说如果程序员们工作到位的话，在dtb里定义好gpio，rfkill就可以搞定硬件复位了。

现在的情况是dtb里定义了gpio但rfkill并没有正确发挥作用，同时那个gpio由于在dtb里定义了系统就不允许再用gpioget/gpioset访问了。

你和“根目录”有着很深的误会

我猜误会的来源是，网上的是emuelec都是通过外接U盘启动的，我说的是U盘根目录，我还看到有个SYSTEM文件有1G+,这里面才是真正系系统吧？这种情况是不是要重新编译
SYSTEM文件才可以呢？

原来U盘系统里的根目录是可写的，参照一楼命令，编辑/storage/.config/custom_start.sh这个文件就搞定了自动连接了

最近我买了一个CM311也在弄蓝牙，参考了这个帖子也遇到了同样的问题。我看了一下coreelec里的gpio数量多了1个，复位蓝牙在armbian操作82脚，到coreelec里是操作83脚，但是83被占用了，可以把coreelec的dtb里占用83脚的那个bt-dev段删除了就可以操作83脚了。

更简单的方法直接用原来的dtb文件，使用命令
rfkill list|grep bt-dev|cut -c1|xargs rfkill unblock
或者直接
rfkill unblock 0
都可以重启蓝牙。rfkill命令操作的就是83管脚，看dtb文件里面也是定义的这个管脚蓝牙复位。

X大，按照你的方法成功用上了蓝牙遥控器，感谢！如果CoreELEC下想实现蓝牙音频，是不是修改rtk_hciattach -n -s 115200 ttyS1 rtk_h5中的115200为2m就行了呢？

不是。

你再看看另一个帖子，需要另一个config文件。这条命令里的速率只是初始化用的，不能改。
