我为嵌入式linux交叉编译了Bluez和d-bus库,然后运行了dbus-daemon和bluetoothd。但是我不能连接bluetoothctl上的设备。扫描工作在bluetoothctl上,甚至连接工作在hcitool上。无法仅在bluetoothctl上连接,并出现此错误:(failed to connect: org.bluez.error.failed) 我怀疑d-b ...

基于C,玩弄bluez的时候总感觉要在代码里去使用bluez的agent极其蛋疼,又没怎么处理过dbus的东西,既然如此,拿现成工具搞起来? 好!如果要直接新开进程bluetoothctl , 可以这样:使用Local socket 去访问,用socketpair 到一个文件流节点,然后 vfork 出进程,用一个循环去读文件流节点,来取得bluetoothctl 的返回值,代码如下:...
