8.6 Running in the ATWILC AP Mode

This section describes how to connect a device to the ATWILC1000 Access Point.

Initialize the ATWILC1000 or ATWILC3000 driver module using the following command:

[root@buildroot ~]# modprobe wilc-sdio
linux_sdio_probe init_power =0
wilc_sdio mmc0:0001:1: Driver Initializing success

Run hostapd as a user configuration using the following command:

# hostapd /etc/wilc_hostapd_open.conf -B &
# Configuration file: /etc/wilc_hostapd_open.conf

Note: See the wilc_hostapd_open.conf file for the unencrypted AP settings and the wilc_hostapd_wpa.conf file for WPA/WPA2/WPA3 AP settings.

Run the DHCP server to allocate the IP to client. Set the IP address to the gateway using the #ifconfig wlan0 192.168.0.1 command.
Note: The gateway IP address is defined in the dhcpd.conf file.
Start the DHCP server using the #/etc/init.d/S80dhcp-server start command.
The user can now connect the PC or smartphone to the ATWILC1000 access point.
To configure the AP in the WPS mode, use the same steps for WPA/WPA2/WPA3 settings, then use the following command to configure to the Push-Button mode:
```
hostapd_cli wps_pbc
```
(or) to configure for the Pin mode, use the following command:
```
hostapd_cli wps_pin any <pin> 
```
