一、配置树莓派3无线wifi连接

如果你有显示器的话，直接打开可视化界面在右上角就可以可视化配置wifi了，很简单。不过很多情况我们是通过ssh连接过去的，也就有必要在终端里配置连接到wifi了。
在树莓派3上由于硬件直接支持了，所以很简单。直接编辑文件即可.先测试一下:

# 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

二、配置树莓派3蓝牙连接

树莓派3也直接支持蓝牙，使用直接使用自带命令即可,先打开要连接的蓝牙设备,然后配置树莓派:

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:

1
sudo apt-get install pulseaudio pulseaudio-module-bluetooth
