7. 网络连接

RV06板卡有多种网络连接方式，包括有线网口连接、wifi连接、USB RNDIS连接。下面分别介绍这三种连接方式。

7.1. 网口连接

  • RV06板卡板载100M有线网口，支持10/100M自适应，支持全双工/半双工自适应，

  • 当网口未插入时,网口的黄灯和绿灯都是熄灭的状态

  • 当系统识别到网口插入时，黄灯会随网络状态闪烁，绿灯会常亮

  • 插入网口后系统会自动获取ip地址，可以通过以下命令查看ip地址

7.2. USB RNDIS连接

RNDIS使用的是固定IP地址： 192.168.137.100

  • RV06板卡的type-c口是otg接口，可以将该接口设置成 device模式

  • 由于RV1106 芯片上只有一个USB2.0的接口，切换使用type-c接口时，需要将type-c接口的usb开启，即需要将板载的拨码开关拨到 ON

  • 运行的时候需要使用usb线连接电脑和板卡上。

c_open

  • 配置文件 /etc/usb_config ，将 OTG_MODE 设置为 peripheral

# cat /etc/usb_config
# OTG_MODE:host or peripheral

# usb_acm_en usb_uac1_en usb_uac2_en usb_uvc_en usb_rndis_en usb_hid_en
GADGET_CONFIG="usb_rndis_en"

  • 将上述文件配置改成下面配置

# usb_acm_en usb_uac1_en usb_uac2_en usb_uvc_en usb_rndis_en usb_hid_en
GADGET_CONFIG="usb_rndis_en"

  • 重启或者执行下面命令生效

3
reboot
# 或
/etc/init.d/S50usbdevice start

RNDIS在Windows系统上是免驱的，所以可以看到 更改适配器选项 中的 网络连接 里会多了下面的设置

rndis_1

7.2.1. 共享网络

如果想让板卡连接上网络，可以启动网络共享

  • 进入 更改适配器选项 中的 网络连接

  • 右击有网络的连接，点击 属性

rndis_2

  • 然后点击 共享 ，勾选 允许其他网络用户通过此计算机的Internet连接来连接 ，点击确定

rndis_3

  • 然后可以看到网络上写着 共享的

rndis_4

这时候板卡就可以连接到电脑上，使用电脑的网络进行上网了。

可以使用在power shell上使用ping查看网络连接情况

rndis_5

7.2.2. 手动设置

如果不想让板子运行在有网络的环境

  • 进入 更改适配器选项 中的 网络连接

  • 右击rndis的连接，点击 属性

rndis_6

  • 双击 Internet协议版本4（TCP/IPv4）

rndis_7

  • 进入配置，按下图配置

rndis_8

  • 最后点击确定，这时候板卡就可以连接到电脑上。

rndis_9

7.2.3. 取消rndis连接

  • 配置文件 /etc/usb_config ，将 OTG_MODE 设置为 host

# cat /etc/usb_config
# OTG_MODE:host or peripheral

# GADGET_CONFIG:usb_mtp_en usb_ums_en usb_ntb_en
# usb_acm_en usb_uac1_en usb_uac2_en usb_uvc_en usb_rndis_en usb_hid_en
GADGET_CONFIG="usb_rndis_en"

  • 将上述文件配置改成下面配置

# cat /etc/usb_config

# usb_acm_en usb_uac1_en usb_uac2_en usb_uvc_en usb_rndis_en usb_hid_en
GADGET_CONFIG="usb_rndis_en"

  • 重启或者执行下面命令生效

1

3
reboot
# 或
/etc/init.d/S50usbdevice stop

7.3. wifi连接

  • RV06板卡板载USB接口的2.4GHz单频WIFI6模块 AIC8800DL

  • 由于RV1106 芯片上只有一个USB2.0的接口，切换使用WIFI时，需要将type-c接口的usb关闭切换到wifi上，需要将板载的拨码开关拨到 1

  • RV06板卡连接WIFI需要连接WiFi天线，天线接口是 ipx-1 类型，需要注意的是，天线需要接到板载模块上面，连接板上的天线接口不会有信号，如下图所示

wifi_open

7.3.1. 配置文件配置wifi

RV06使用 wpa_supplicant 工具进行wifi连接，连接wifi前需要先配置wifi的ssid和密码，配置文件路径为 /etc/wpa_supplicant.conf

1
2
3
4
5
6
7
8
9
# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
        ssid="aEBF_Guest"
        psk="BQTH4kH9"
        key_mgmt=WPA-PSK
}

  • 配置文件中ssid和psk为需要连接的wifi的名称和密码，key_mgmt为加密方式，WPA-PSK为WIFI密码加密方式

  • 配置文件中可以配置多个wifi，系统会自动选择信号最好的wifi进行连接

7.3.2. wpa_cli连接wifi

  • 使用 wpa_cli 工具连接wifi，命令行输入下面命令，进入配置

wpa_cli
