如何用wifi-linux检测AP信号强度

安装wifi-linux需要的包。

用下面命令中的系统包管理工具来安装Python DBUS。

sudo apt-get install python-dbus

上面的命令只有在有apt-get包管理器的机器中才可以使用，比如Debian和Ubuntu。

要安装的第二个依赖是gnuplot-py。下载并用tar解压，接着运行setup.py来安装包。

第一步是下载gnuplot-py。

接着使用tar工具解压。

tar xvf gnuplot-py-1.8.tar.gz

接着使用cd命令改变目录。

cd gnuplot-py-1.8

接着运行下面的命令在你的系统中安装gnuplot-py。

sudo setup.py install

安装完成后，你就可以在你的系统中运行wifi-linux了。只需下载并用下面的命令运行脚本。

用下面的命令下载wifi-linux到你的机器中。

解压master.zip接着使用下面的命令运行list_rsssi.py脚本。

python list_rssi.py

至此wifi-linux在工作了。

命令bp用于像添加一个断点。

命令print可以用于在终端上显示你机器的状态。

不知道为什么，小米的蓝牙鼠标在linux下面安装不是很顺利，系统能够识别出蓝牙鼠标，但是自作多情的识别出了一堆，如图所示：

看着不爽啊，怎么办？祭出bluetoothctl大法，下面是bluetoothctl的执行过程：

$ bluetoothctl

[bluetooth]# remove EA:36:73:C7:64:C5

全部删除MiMouse设备，然后重新发现和连接即可。

小经验：最好通过bluetoothctl执行trust指令将MiMouse加入信任设备列表，这样配对的时候不需要验证。
