8.5 Running in the ATWILC Station Mode

The following example shows how to run the ATWILC device in Station mode and connect to an AP.

  1. Initialize the ATWILC1000 and ATWILC3000 driver module using the following command:
    Welcome to Buildroot
buildroot login: root
root@buildroot ~]# modprobe wilc-sdio
linux_sdio_probe init_power =0
wilc_sdio mmc0:0001:1: Driver Initializing success
  2. Start the WPA supplicant service and execute wpa_supplicant using the following command:
    # wpa_supplicant -iwlan0 -Dnl80211 -c /etc/wilc_wpa_supplicant.conf &
# Successfully initialized wpa_supplicant

  3. Connect to the Access Point:
    1. To connect to an unsecured AP:

      Use the following commands to scan and connect to the AP.

      # wpa_cli -p/var/run/wpa_supplicant ap_scan 1 
# wpa_cli -p/var/run/wpa_supplicant add_network 
# wpa_cli -p/var/run/wpa_supplicant set_network 0 ssid '"User_AP"' 
# wpa_cli -p/var/run/wpa_supplicant set_network 0 key_mgmt NONE 
# wpa_cli -p/var/run/wpa_supplicant select_network 0
      Note: Change the User_AP with the Service Set Identifier (SSID) of the desired AP.
    2. To connect to the WPA secured Access Point:

      Use the following commands to scan and connect to a WPA or WPA2 and Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES) protected AP.

      # wpa_cli -p/var/run/wpa_supplicant ap_scan 1 
# wpa_cli -p/var/run/wpa_supplicant add_network 
# wpa_cli -p/var/run/wpa_supplicant set_network 0 ssid '"User_AP"'
# wpa_cli -p/var/run/wpa_supplicant set_network 0 key_mgmt WPA-PSK 
# wpa_cli -p/var/run/wpa_supplicant set_network 0 psk '"12345678"' 
# wpa_cli -p/var/run/wpa_supplicant select_network 0
      Note: Change the User_AP and 12345678 with the SSID and password of the desired AP.
    3. To connect to the WPA2/WPA3 secured Access Point:

      Use the following commands to scan and connect to a WPA2 or WPA3 and Counter Mode CBC-MAC Protocol (CCMP) or Advanced Encryption Standard (AES) protected AP.

      # wpa_cli -p/var/run/wpa_supplicant ap_scan 1 
# wpa_cli -p/var/run/wpa_supplicant add_network 
# wpa_cli -p/var/run/wpa_supplicant set_network 0 ssid '"User_AP"'
# wpa_cli -i wlan0 set_network 0 ieee80211w 1
# wpa_cli -i wlan0 set_network 0 key_mgmt SAE WPA-PSK WPA-PSK-SHA256
# wpa_cli -i wlan0 set_network 0 pairwise CCMP
# wpa_cli -i wlan0 set_network 0 group CCMP
# wpa_cli -iwlan0 set_network 0 psk '"1234567811"'
# wpa_cli -i wlan0 set_network 0 sae_password '"1234567890"'
# wpa_cli -i wlan0 set_network 0 proto RSN
# wpa_cli -iwlan0 select_network 0
      Note: Change the User_AP, 1234567811 and 1234567890 with the SSID, password and sae_password of the desired AP.
    4. To connect to the WPA3 (only) secured Access Point:

      Use the following commands to scan and connect to a WPA3 and Counter Mode CBC-MAC Protocol (CCMP) or Advanced Encryption Standard (AES) protected AP.

      # wpa_cli -p/var/run/wpa_supplicant ap_scan 1 
# wpa_cli -p/var/run/wpa_supplicant add_network 
# wpa_cli -p/var/run/wpa_supplicant set_network 0 ssid '"User_AP"'
# wpa_cli -i wlan0 set_network 0 ieee80211w 1
# wpa_cli -i wlan0 set_network 0 key_mgmt SAE
# wpa_cli -i wlan0 set_network 0 pairwise CCMP
# wpa_cli -i wlan0 set_network 0 group CCMP
# wpa_cli -i wlan0 set_network 0 sae_password '"1234567890"'
# wpa_cli -i wlan0 set_network 0 proto RSN
# wpa_cli -iwlan0 select_network 0
      Note: Change the User_AP and 1234567890 with the SSID and sae_password of the desired AP.
    5. Connect to the WPS secured Access Point Trigger WPS Push-Button mode using the following command: 
      wpa_cli wps_pbc
      (or) to connect using PIN method, use the following command:
      sudo wpa_cli wps_pin any <the pin>
  4. Run the DHCP service.

    If the IP address can be allocated from the AP automatically, start the DHCP client using the following command:

    #dhcpcd wlan0 &
    Note: If the AP does not support the DHCP service, manually set the static IP address value using the ifconfig wlan0 xxx,xxx.xxx.xxx command.
  5. Check and validate the connection status using the following commands:
    # wpa_cli status

bssid=88:9b:39:f3:d0:4d
ssid=User_AP
id=0
mode=station
pairwise_cipher=NONE
group_cipher=NONE
key_mgmt=NONE
wpa_state=COMPLETED
ip_address=192.168.43.2
address=00:80:c2:b3:d7:4d

    The user can save and use the network information to automatically connect to the network using the wpa_cli save command in Linux.
