OrangePI蓝牙使用

前言

我使用的板子是OrangePI zero Plus2，基于全志H5。我在上面安装好了armbian系统。我现在要使用蓝牙功能，对接我的蓝牙耳机。

安装Bluez

linux上的蓝牙官方协议即为Bluez。所以需要先安装Bluez：

root@H5:~# apt-get install bluez bluez-tools

安装完成后可以观察到系统上多出了几个工具：

root@H5:~# hci
hciattach  hciconfig  hcitool 

使用工具：

root@H5:~# hciconfig 
root@H5:~# 

发现并没有蓝牙设备。

开启蓝牙设备

接下来我在网络上寻找解决方法。找到armbian论坛中的这个帖子，其中thc013网友描述到：

enable overlay uart 1 and add param_uart1_rtscts=1 to armbianenv.txt and adjust /etc/init.d/ap6212-bluetooth so it looks like this
sh # Start patching rfkill unblock all echo "0" > /sys/class/rfkill/rfkill0/state echo "1" > /sys/class/rfkill/rfkill0/state echo " " > /dev/$PORT devmem2 0x1f00060 b 1 echo 10 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio10/direction echo 0 > /sys/class/gpio/gpio10/value echo 1 > /sys/class/gpio/gpio10/value sleep 0.1 hciattach /dev/$PORT bcm43xx 115200 flow bdaddr $MAC_OPTIONS hciconfig hci0 up
and reboot
oh you might need to install devmem2

当然我要尝试使用这个方法了。

1. 首先使能覆盖串口1
   根据描述这个应该是在armbianEnv.txt中，我当即去寻找这个文件,这文件应该是在启动分区中的，所以我想将启动分区mount后去修改。

   root@H5:~# mount /dev/mmcblk2boot1 /mnt
   mount: /dev/mmcblk2boot1 is write-protected, mounting read-only
   mount: wrong fs type, bad option, bad superblock on /dev/mmcblk2boot1,
      missing codepage or helper program, or other error
   
      In some cases useful info is found in syslog - try
      dmesg | tail or so.

   然后我发现这个armbian系统和一般的系统不太一样。boot相关文件不需要挂载直接可以查看：

   root@H5:~# cd /boot/
   root@H5:/boot# ls
   armbianEnv.txt                  dtb-4.16.0-sunxi64
   armbian_first_run.txt.template  Image
   boot.bmp                        initrd.img-4.16.0-sunxi64
   boot.cmd                        System.map-4.16.0-sunxi64
   boot-desktop.png                uInitrd
   boot.scr                        uInitrd-4.16.0-sunxi64
   config-4.16.0-sunxi64           vmlinuz-4.16.0-sunxi64
   dtb
   root@H5:/boot# vi armbianEnv.txt

   在overlays后添加上了uart1，以及又添加了一行param_uart1_rtscts=1

2. 调整/etc/init.d/ap6212-bluetooth
   编辑这个文件

   root@H5:~# vi /etc/init.d/ap6212-bluetooth

   根据上面的帖子去修改这个文件。

3. 安装devmem2
   这是一个内核调试实用的工具，需要安装的话使用这个链接
   将软件包传入板子内安装：

   root@H5:~# dpkg -i devmem2_0.0-0ubuntu1_arm64.deb
   Selecting previously unselected package devmem2.
   (Reading database ... 31834 files and directories currently installed.)
   Preparing to unpack devmem2_0.0-0ubuntu1_arm64.deb ...
   Unpacking devmem2 (0.0-0ubuntu1) ...
   Setting up devmem2 (0.0-0ubuntu1) ...
   Processing triggers for man-db (2.7.6.1-2) ...

   安装完成重启测试蓝牙功能。

4. 失败
   我发现这个方法并不可行，我现在对这个方法有所了解了。他其实是使用这个方式开启蓝牙：

   root@H5:~# /etc/init.d/ap6212-bluetooth start
   [....] Starting ap6212-bluetooth (via systemctl): ap6212-bluetooth.serviceWarning: ap6212-bluetooth.service changed on disk. Run ‘systemctl daemon-reload‘ to reload units.

   尝试别的解决方法

我找了一天，刷了十几个镜像，这次使用Orange PI官方的镜像：ubuntu_xenial_zeroplus2_H5_V0_3.img。
我首先安装上了这个镜像，进入了root账户。

1. 升级软件包
   这里升级软件包时出现了一些错误，使用我这个命令将其修复。

   root@Orangepi:~# apt-get update
   Hit:1 http://ports.ubuntu.com xenial InRelease
   Hit:2 http://ports.ubuntu.com xenial-updates InRelease
   Hit:3 http://ports.ubuntu.com xenial-security InRelease

   Reading package lists... Error!
   E: Unable to parse package file /var/lib/dpkg/status (1)
   W: You may want to run apt-get update to correct these problems
   E: The package cache file is corrupted

2. 安装bulez

   安装好之后查看蓝牙设备，当然不出我所料是没有蓝牙设备的，因为我在这个文件系统的/etc/init.d/下没有看到和蓝牙启动相关的脚本。

   root@Orangepi:~# hciconfig hci0
   Can‘t get device info: No such device

3. 启动蓝牙
   我根据之前的启动蓝牙方法，尝试了如下命令：

   rfkill unblock all
   echo "0" > /sys/class/rfkill/rfkill0/state
   echo "1" > /sys/class/rfkill/rfkill0/state
   echo " " > /dev/ttyS1
   sleep 0.1
   hciattach /dev/ttyS1 bcm43xx 115200 flow bdaddr 43:29:B1:55:01:01

   执行结果(这里是前面的命令都执行了一遍)：

   root@Orangepi:~# hciattach /dev/ttyS1 bcm43xx 115200 flow bdaddr 43:29:B1:55:01:01
   bcm43xx_init
   Patch not found, continue anyway
   Set BDADDR UART: 43:29:B1:55:01:01
   Set Controller UART speed to 115200 bit/s
   Device setup complete
   root@Orangepi:~# hciconfig

   root@Orangepi:~# hcitool scan
   Scanning ...
       22:22:B8:95:DE:DC       X800+

   总结

经过以上尝试，我觉得他们官方的镜像应该都可以。

1. 我觉得这个ubuntu xenial太过臃肿，我想用ubuntu server版，但是没有尝试，因为刷镜像太过烦恼。。。
2. 我之前的那个方法不行，应该是因为我使用的armbian基于4.16内核的镜像。但是我这个板子他不支持armbian 4.14内核的镜像，会无限重启。后来我下载了Armbian源代码，自行编译出Armbian_5.45_Orangepizeroplus2-h5_Debian_stretch_next_4.14.44.img这个镜像。这个也值得一试，毕竟armbian是定制的镜像，效率会高很多，发热量也很小。
3. 当然我觉得也可以在armbian上直接使用Orange Pi官方的wifi驱动，因为蓝牙不能用大概率是因为内核驱动的问题。

后记

我试了Armbian_5.45_Orangepizeroplus2-h5_Debian_stretch_next_4.14.44.img的镜像，然后进行了以下两步：

1. 使能uart1

   root@H5:/# vi /boot/armbianEnv.txt

   修改如下：

   verbosity=1
   console=both
   overlay_prefix=sun50i-h5
   + overlays=usbhost2 usbhost3 uart1
   rootdev=UUID=73662019-22c8-4039-a605-680b57d0fb1c
   rootfstype=ext4
   + param_uart1_rtscts=1
   usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

2. 修改蓝牙服务

   root@H5:/# vi /etc/init.d/ap6212-bluetooth

   修改如下

   # Start patching
   rfkill unblock all
   echo "0" > /sys/class/rfkill/rfkill0/state
   echo "1" > /sys/class/rfkill/rfkill0/state
   echo " " > /dev/$PORT
   +devmem2 0x1f00060 b 1
   #on orangepi win following command never ends on first try... force to run with a timeout...
   -timeout 5s echo " " > /dev/$PORT
   -if [ $? != 0 ]; then
   -        #timed out... retry
   -        echo " " > /dev/$PORT
   -fi
   hciattach /dev/$PORT bcm43xx 115200 flow bdaddr $MAC_OPTIONS
   hciconfig hci0 up

3. 启动蓝牙

   root@H5:/# /etc/init.d/ap6212-bluetooth start
   [....] Starting ap6212-bluetooth (via systemctl): ap6212-bluetooth.serviceWarning: ap6212-bluetooth.ser.
   . ok
   root@H5:/# hciconfig
   hci0:   Type: Primary  Bus: UART
           BD Address: 43:29:B1:55:01:01  ACL MTU: 1021:8  SCO MTU: 64:1
           DOWN
           RX bytes:696 acl:0 sco:0 events:42 errors:0
           TX bytes:2214 acl:0 sco:0 commands:42 errors:0

   启动成功
