开启 SSH 连接

• boot 目录下新建 ssh 的空文件
• boot 目录下新建 wpa_supplicant.conf

country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
 
network={
ssid="Limour123"
psk="123456"
key_mgmt=WPA-PSK
priority=5
}
 
network={
ssid="Redmi_719_2.4G"
psk="123456"
key_mgmt=WPA-PSK
priority=1
}

蓝牙局域网设置

sudo apt install bridge-utils bluez python-dbus python-gobject bluez-tools
sudo ufw disable # 关闭防火墙
sudo service bluetooth start # 开启蓝牙服务并设置为开机自启
sudo update-rc.d bluetooth enable

sudo nano /etc/systemd/network/pan0.netdev
# 输入:
[NetDev]

Kind=bridge

sudo nano /etc/systemd/network/pan0.network
# 输入:
[Match]

连接蓝牙局域网

bluetoothctl # 启动蓝牙命令行工具
agent on # 开启代理
scan on # 扫描设备
pair 9C:19:C2:4D:88:DC # 树莓派与蓝牙设备进行配对
connect 9C:19:C2:4D:88:DC  # 连接设备

• win11 上右键蓝牙加入个人区域网
• 树莓派上 ifconfig 可以看到多了一个 bnep0 的网络
• win11 上 ipconfig.exe 可以看到多了一个以太网适配器 蓝牙网络连接
• 其默认网关为 172.20.1.1
• 此时 win11 上 ssh 连接 172.20.1.1 即可连接到树莓派
