WiFi

 RV1109/RV1126 uses connman to manage WiFi by default and
wpa_supplicant is the key process for WiFi:

   ps -ef
   #You can see the following two processes
   connmand			 #It uses dbus to communicate with wpa_supplicant
   wpa_supplicant -u  #Turns on support for dbus communication

Standard usage method: WiFi operation is carried out through the
RV1126/RV1109 web interface, refer to the relevant documents of
RV1109/RV1126 platform:

Terminal simple test method is as follows:

   killall ipc-daemon netserver
   connmanctl
   connmanctl> enable wifi
   connmanctl> scan wifi #Allows multiple scans
   connmanctl> scan wifi #Allows multiple scans
   connmanctl> agent on
   connmanctl> services
   #List the scanned WiFi list
   connmanctl>

   ifconfig wlan0
   #See the IP address of wlan0

If you don't want to use connman and use the traditional
wpa_supplicant/wpa_cli approach, do the following

   #Close the default camera application
   /oem/RkLunch-stop.sh
   #Unlock peripheral devices
   rfkill unblock all
   killall wpa_supplicant
   #Modify the wpa_supplicant.conf configuration file
   vi /etc/wpa_supplicant.conf
   #Replace SSID with WIFI name
   #Replace PASSWORD with WiFi PASSWORD
   wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B & #WiFi WPA_Supplicant Background Connection
   udhcpc -i wlan0 #Obtains IP address after successful WiFi connection

ping test whether wlan0 is connected to the external network

   #The following results indicate a successful connection
