3 How to Use
The WiFi adapter WIFI 011 can be operated either as a client or as an access point. If the
WIFI 011 is to be used as a client, unlike the HGW 1033-X, the client mode is not started
automatically (without command in the "autoexec.lsl"), since the AP mode can be activated
via an application, for example. In this case it would be necessary to deactivate the client
mode before.
With the following CLI or autoexec.lsl commands the desired mode can be selected or started
without application.
"WLANCLIENT START 10"
or
WLANAP 10 (this command was already available)
3.1 Client
There are two ways to use the WLAN Client. To handle the WiFi adapter, you can edit the
configuration file and start the client like described below. On the other hand, SIGMATEK
provides a LASAL class to be used with the WiFi adapter.
3.2 Configuration File
The configuration of the network (the access point to which the client should connect) can be
set in the configuration file:
“C:\LSLSYS\WIRELESS.CONF”
This file is located on the control and must be adapted. The entries for “ssid”and “psk”must
exist.
Important: The line with the option "update_config=1" is required so that configuration
changes are saved permanently.
Please note that when overwriting the configuration file, the comments from it are removed.
# This is the configuration file to handle the connection with
wireless networks via interface 10.
# To connect to a Wireless Access Point, use one of the methods be-
low
# (remove '#' in front of the line) depending on the security
method of the access point.
#
# NOTE: Don't touch the first line!
ctrl_interface=/var/run/wpa_supplicant
update_config=1

# Configuration for not secure networks (no key)
#network={
# ssid="WirelessNetworkName"
# key_mgmt=NONE
#}
# Configuration for WPA/WPA2 networks
network={
ssid="sigmatek_internet"
psk="xxxpasswordxxx"
}
Starting the WLAN client:
“C:\AUTOEXEC.LSL”
e.g.
SET IP 10 HOSTADDR DHCP
3.3 Class “WLAN_ClientControl”
SIGMATEK provides a LASAL class with the functions to handle the WiFi adapter. Refer to
the online help of LASAL CLASS 2 and the documentation of the class “WLAN_ClientCon-
trol”.
With the functions in the class “WLAN_ClientControl”you can also connect to other access
points during runtime.
3.4 Configuration File (access point)
If the WiFi adapter WIFI 011 is to be operated as an access point, it must be configured
with the configuration file "C:\LSLSYS\HOSTAPD10.CONF".
The file is available in the directory "C:\LSLSYS\DEFAULT-CONFIGURATIONS" and must
be copied into the directory "C:\LSLSYS".
The basic settings in this file should be left as they are.
The setting for the password "wpa_passphrase" should be changed in any case.

3.5 "WLAN_APControl" Class
SIGMATEK provides a LASAL class with the functions for handling the WiFi adapter. Refer
to the online help of LASAL CLASS 2 and the documentation of the "WLAN_APControl"
class.
You can also use the functions in the "WLAN_APControl" class to start, stop and configure
the AP at runtime.

4 Hotplug
Starting from OS version 09.03.210 hotplug is supported for the stick WIFI 011.
The following functionalities are realized:
•If the stick is configured in the "autoexec.lsl", the settings of the "autoexec.lsl" are taken
over at the start of the control, it is not relevant whether the stick is plugged in or not.
•If the stick is plugged in, the settings of "autoexec.lsl" are executed immediately. The
configured IP address is set and the client or access point is started.
•If the stick is not plugged in, the settings of "autoexec.lsl" are executed when the stick
is plugged in.
•If the stick is unplugged during operation, the current settings are restored when it is
plugged in again.
•Even if the stick was not configured or reconfigured in "autoexec.lsl" but via an applica-
tion, the last settings are always restored when the stick is plugged in and unplugged.
