标题:USB 蓝牙适配器在ARM 开发板下的使用:
关键字: dbus,bluez-lib, bluez-utils, USB 蓝牙,ARM
正文:
1、我的操作环境是
主机:xp + VMware ubuntu 10.10 。 开发板:OK6410 。 文件系统: yaffs2 。 蓝牙:蓝牙适配器(适配器在PC ubuntu 下测试可用)。交叉编译器:arm-linux-gcc 4.3.2
操作环境环境提示:如果你有red hat 或者 Fedora 这两个操作环境,建议你首选这两个环境,应为Ubuntu 操作起来问题太多了。
2、配置内核支持Bluetooth,

3.1 所依赖的库文件:
bluez-libs-3.36.tar.gz
dbus-1.5.12.tar.gz
expat-2.0.1.tar.gz
glib-2.26.1.tar.gz
bluez-utils-3.36.tar.gz
libusb-0.1.12.tar.gz
应用的安装步骤:
3.2,编译安装bluez-lib-3.36.tar.gz
这个库不需要什么依赖,直接解压,配置,编译然后安装即可。
#tarzxvfbluez-lib-3.36.tar.gz
#./configure--profix=/opt/libs--host=arm-linux--target=arm-linuxCC=arm-linux-gcc
#make
#makeinstall
3.3,编译安装expat-2.0.1.tar.gz
这个库是后面的dbus依赖的,你也可以用libxml2来代替expat,官方网站上说dbus必须依赖于他们中的一个,我这里用的是expat-2.0.1.tar.gz。
#tarzxvfexpat-2.0.1.tar.gz
#./configure--profix=/opt/libs--host=arm-linux--target=arm-linuxCC=arm-linux-gcc
#make
#makeinstall
3.4,编译安装dbus-1.5.12.tar.gz
#tarzxvfdbus-1.5.12.tar.gz
#echoac_cv_have_abstract_sockets=yes>arm-linux.cache
#./configure--profix=/opt/libs--host=arm-linux--target=arm-linuxCC="arm-linux-gcc-I/opt/libs/include-L/opt/libs/lib"--cache-file=arm-linux.cache--with-x=no
#make
#makeinstall
3.5,编译安装glib-2.26.1.tar.gz
#tar-zxjfglib-2.26.1.tar.gz
#echoac_cv_type_long_long=yes>arm-linux.cache
#echoglib_cv_stack_grows=no>>arm-linux.cache
#echoglib_cv_uscore=no>>arm-linux.cache
#echoc_cv_func_posix_getpwuid_r=yes>>arm-linux.cache
#echoac_cv_func_posix_getgrgid_r=yes>>
注意:">"和">>"的区别
#./configure--profix=/opt/libs--host=arm-linux--target=arm-linuxCC="arm-linux-gcc-I/opt/libs/include-L/opt/libs/lib"--cache-file=arm-linux.cache
#make
#makeinstall
3.6,编译安装libusb-0.1.12.tar.gz
这个库不需要什么依赖,直接解压,配置,编译然后安装即可。
#tarzxvflibusb-0.1.12.tar.gz
#./configure--profix=/opt/libs--host=arm-linux--target=arm-linuxCC="arm-linux-gcc-I/opt/libs/include-L/opt/libs/lib"
#make
#makeinstall
3.7,编译安装bluez-utils-3.36.tar.gz
#tarzxvfbluez-utils-3.36.tar.gz
#./configure--profix=/opt/libs--host=arm-linux--target=arm-linuxCC="arm-linux-gcc-I/opt/libs/include-L/opt/libs/lib"--disable-audio
#make
#makeinstall
4、可能出现的问题和解决方案:
4.1 编译dbus 时出现:
1checking for accept4... yes
checking abstract socket namespace... no
checking for pkg-config... (cached) /usr/local/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for XML_ParserCreate_MM in -lexpat... no
configure: error: Could not find expat.h, check config.log for failed attempts
解决方案:
export LDFLAGS=-Wl,-L/usr/local/lib,-lexpat
export CPPFLAGS=-I/usr/local/include
4.2 安装glib 时出现glib msgfmt.. no (这个问题极易出现在Ubuntu 上)
解决方案:apt-get install gettest
4.3 安装glib 时出现error: Could not find a glib-genmarshal in your PATH,
解决方案:先在主机安装 apt-get install libglib2.0-dev
4.4 bluez-utils ./configure 时出现:BLUEZ no Bluetooth library is required
解决方案:sudo apt-get install libbluetooth-dev
4.5 bluez-utils ./configure 时出现:configure: error: D-Bus library is required
解决方案:sudo apt-get install libdbus-1-dev libdbus-glib-1-dev
4.5 bluez-utils 编译 make 时出现bluez libgmodule-2.0.so could not read symbols: File in wrong 等
解决方案: 查看 glib 配置时的 arm-linux.cache 和环境变量的配置,问题极有可能出现在这里
5 bluez 测试
5.1 测试准备
在自己配置 ./configure --prefix=/opt/libs 时 说明自己的库会被安装在/opt/libs 下
copy /opt/libs/sbin/* 到你的文件系统 /sbin
copy /opt/libs/bin/ 下的hcitool,rfcomm,sdptool 到你的文件系统 /bin
copy /opt/libs/etc/bluetooth/* 到你的文件系统 /etc
5.2 测试命令
[root@FORLINX6410]# hciconfig hci0 up 启用蓝牙
[root@FORLINX6410]# hciconfig hci0 iscan配置开发板蓝牙可被查找
[root@FORLINX6410]# hcitool scan 查找蓝牙
