8.8.1 Running the ATWILC Device in Station and AP Modes Concurrently

The following section describes the configuration steps to run the ATWILC device in the Station (STA) and AP modes, concurrently.

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 -Dnl80211 -iwlan0 -c/etc/wilc_wpa_supplicant.conf &
   Successfully initialized wpa_supplicant
   rfkill: Cannot open RFKILL control dev
   wilc_sdio mmc0:0001:1 wlan0: Detect chip WILC3000
   wilc_sdio mmc0:0001:1 wlan0: loading firmware wilc3000_wifi_firmware.bin
   wilc_gnrl_async_info_received
   wilc_sdio mmc0:0001:1 wlan0: WILC Firmware Ver = WILC_WIFI_FW_REL_15_00 Build: 8719
   

3. Connect to the Access Point using the following command:

   # 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

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 &

5. Ping the User AP to check the connection using the following command:

   # ping 192.168.0.1

6. Add the p2p0 virtual interface:

   iw phy0 interface add p2p0 type station

7. Run the hostapd as a user configuration, making sure that the .conf file uses the p2p0 interface:

   # hostapd /etc/wilc_hostapd_open.conf -B &
   
   Configuration file: /etc/wilc_hostapd_open.conf
   rfkill: Cannot open RFKILL control device
   wilc_sdio mmc0:0001:1 wlan0: Detect chip WILC3000
   wilc_sdio mmc0:0001:1 wlan0: loading firmware wilc3000_wifi_firmware.bin
   wilc_gnrl_async_info_received
   wilc_sdio mmc0:0001:1 wlan0: WILC Firmware Ver = WILC_WIFI_FW_REL_15_00 Build: 8719
   Using interface wlan0 with hwaddr fa:f0:05:f6:56:6a and ssid "wilc_SoftAP"
   wilc_gnrl_async_info_received
   wilc_sdio mmc0:0001:1 wlan0: there is no current Connect Request
   wlan0: interface state UNINITIALIZED->ENABLED
   wlan0: AP-ENABLED

8. Run the DHCP Server to allocate the IP to client.
   • Set the IP of AP; #ifconfig p2p0 192.168.0.1
   • Start the DHCP server; #/etc/init.d/S80dhcp-server start

     The user can connect the PC or smartphone to the ATWILC1000 AP.
