RDK X5 Network — 网络与蓝牙配置

操作步骤

1. 查看网络状态

ip addr show                   # 所有接口 IP
nmcli device status            # 连接状态总览
nmcli device wifi list         # 扫描可用 WiFi

2. 连接 WiFi

# 连接（替换 SSID 和 PASSWORD）
sudo nmcli device wifi connect "SSID" password "PASSWORD"

# 连接隐藏 WiFi
sudo nmcli device wifi connect "SSID" password "PASSWORD" hidden yes

# 查看 / 删除已保存连接
nmcli connection show
sudo nmcli connection delete "连接名"

3. 创建 WiFi 热点

sudo nmcli device wifi hotspot ifname wlan0 ssid "RDK-X5-AP" password "12345678"

# 关闭热点
sudo nmcli connection down Hotspot

4. 配置有线静态 IP

sudo nmcli connection modify "Wired connection 1" \
  ipv4.method manual \
  ipv4.addresses "192.168.1.100/24" \
  ipv4.gateway "192.168.1.1" \
  ipv4.dns "8.8.8.8,114.114.114.114"
sudo nmcli connection up "Wired connection 1"

# 恢复 DHCP
sudo nmcli connection modify "Wired connection 1" ipv4.method auto
sudo nmcli connection up "Wired connection 1"

5. 蓝牙配对

sudo systemctl start bluetooth
bluetoothctl

在 bluetoothctl 交互中：

1. scan on — 扫描设备
2. pair XX:XX:XX:XX:XX:XX — 配对
3. connect XX:XX:XX:XX:XX:XX — 连接
4. quit — 退出

6. SSH / VNC 远程访问

# SSH 开启
sudo systemctl enable ssh && sudo systemctl start ssh

# VNC 开启（通过 srpi-config）
sudo srpi-config
# → Interface Options → VNC → Enable

7. srpi-config 快速配置

sudo srpi-config

支持：WiFi、SSH/VNC 开关、40pin 总线、MIPI 屏幕选择、音频通道切换。

排查故障

现象	排查命令	解决
无法上网	ping -c 4 8.8.8.8	检查网关：ip route show
DNS 解析失败	cat /etc/resolv.conf	手动设置 DNS：sudo nmcli conn modify ... ipv4.dns "114.114.114.114"
WiFi 扫描为空	nmcli radio wifi	若 disabled 则 nmcli radio wifi on
网络服务异常	sudo systemctl status NetworkManager	sudo systemctl restart NetworkManager
