10. 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
[root@RV1126_RV1109:/]# ifconfig wlan0
