可以看到周围的wifi热点信息
配置连接到某个热点:


# 编辑wifi文件
sudo vim /etc/wpa_supplicant/wpa_supplicant.conf
# 在该文件最后添加下面的话
network={
  ssid="WIFINAME"
  psk="password"
}
# 引号部分分别为wifi的名字和密码
# 保存文件后几秒钟应该就会自动连接到该wifi
# 查看是否连接成功
ifconfig wlan0

这样就连上蓝牙设备了，如果是蓝牙音响的话还得装下支持软件:


sudo apt-get install pulseaudio pulseaudio-module-bluetooth
