bluez5编译时
编译错误1：
CC tools/mpris-proxy.o
src/shared/shell.c:25:10: fatal error: wordexp.h: No such file or directory
#include buildroot-2023.02.6/output/build/bluez5_utils-5.65$
vim ./src/shared/shell.c
#include
改为：
#include
buildroot-2023.02.6/output/build/bluez5_utils-5.65$ grep -r ""
client/player.c:#include 把下面五个改一下就OK了！
src/shared/shell.c:#include 编译错误2：
src/shared/shell.c: In function 'cmd_exec':
src/shared/shell.c:419:11: error: 'WRDE_APPEND' undeclared (first use in this function); did you mean 'WRDE_NOCMD'?
flags |= WRDE_APPEND;
^~~~~~~~~~~
WRDE_NOCMD
src/shared/shell.c:419:11: note: each undeclared identifier is reported only once for each function it appears in
CC tools/rctest.o

Makefile:82: recipe for target '_all' failed
make: *** [_all] Error 2
将WRDE_APPEND改为：WRDE_NOCMD
/* Check if there are enough arguments */
if ((unsigned) argc - 1 < w.we_wordc) {
print_text(COLOR_HIGHLIGHT, "Missing %s argument",
w.we_wordv[argc - 1]);
goto fail;
}
//flags |= WRDE_APPEND; // liefyuan commit
flags |= WRDE_NOCMD;
opt = strdup(entry->arg + len + 1);
OK编译完毕！
查看一下各个软件的依赖关系
命令：make graph-depends
这需要安装graphviz
sudo apt-get install graphviz
生成在：output/graphs/
最终的配置

BR2_PACKAGE_BLUEZ5_UTILS_EXPERIMENTAL=y
BR2_TARGET_ROOTFS_EXT2=y
BR2_TARGET_ROOTFS_EXT2_4=y
把上面保存为xxx_defconfig
我的Buildroot版本是：buildroot-2023.02.6
使用方法：
- 加载旧配置：
make ARCH=arm xxx_defconfig将会生成.config文件 - 修改配置：
make ARCH=arm menuconfig修改配置后保存 - 保存配置（.config）：
make ARCH=arm savedefconfig生成defconfig文件 - 永久保存配置（defconfig）：
cp defconfig /configs/xxx_v0.2_defconfig保存
最终生成的文件系统才14.5MB。
测试
使用hciconfig -a 可以查看出蓝牙版本号：
- 蓝牙版本 4.0 (0x6)
- 蓝牙版本 4.1 (0x7)
- 蓝牙版本 4.2 (0x8)
- 蓝牙版本 5.0 (0x9)
- 蓝牙版本 5.1 (0xa)
- 蓝牙版本 5.2 (0xb)
- 蓝牙版本 5.3 (0xc)
- 蓝牙版本 5.4 (0xd)

rfkill 系统射频开关
不只是蓝牙，包括WiFi，eth都是通过rfkill来控制的。
echo 1 > /sys/class/rfkill/rfkill2/state # 打开对应的射频设备开关
echo 0 > /sys/class/rfkill/rfkill2/state # 关闭对应的射频设备开关
可以查看各个设备节点信息去确认它是个啥？
# cat /sys/class/rfkill/rfkill0/uevent
RFKILL_NAME=bt_default
RFKILL_TYPE=bluetooth
RFKILL_STATE=0
# cat /sys/class/rfkill/rfkill1/uevent
RFKILL_NAME=phy0
RFKILL_TYPE=wlan
RFKILL_STATE=1
# cat /sys/class/rfkill/rfkill2/uevent
RFKILL_NAME=hci0
RFKILL_TYPE=bluetooth
RFKILL_STATE=0
RFKILL_STATE：其实就是表示他是个什么状态，0就是关闭，1就是打开。
通过echo 0 > /sys/class/rfkill/rfkill2/state来设置对应的状态
hciconfig
对应于WiFi里面的ifconfig,所以可以这么操作：
hciconfig hci0 up：打开蓝牙0的开关hciconfig -a：查看所有的蓝牙设备信息
其他的命令：
- 打开/关闭/重置hci设备：
hciconfig hci0 up/down/reset - 认证打开/关闭：hciconfig
hci0 auth/noauth，直接体现在进行蓝牙连接时，是否输入连接PIN密码，用于PIN配对 - 查看/改变蓝牙主从状态：
hciconfig hci0 lm、hciconfig hci0 lm slave - 查看/设置蓝牙名称：
hciconfig hci0 name、hciconfig hci0 name Donge - 开启/关闭广播：
hciconfig hci0 leadv/ noleadv - 查看支持的链路层状态：
hciconfig hci0 lestates

bluetoothctl
这是一个交互命令行，运行该软件后会进入另一个交互命令。不过我不知道为什么我在这个交互命令行里面输入命令它都没有反应。
