Further information about conﬁguring the WLAN interface can be taken from wpa_supplicant’s

manual page (man wpa_supplicant) .

mands:

ifconfig wlan0 down

iwconfig wlan0 mode ad-hoc key off essid "Node1"

4.1.3. WLAN On/Oﬀ Button (Alekto LAN only)

OnRISC Alekto LAN provides a special button to enable/disable the WLAN adapter. Pressing

the button will result in button LED going oﬀ and WLAN transmit power turning oﬀ, so no

communication via WLAN is possible. Pressing the button for the second time will result in button

LED going on and WLAN transmit power returning to the previous value, so WLAN data transfer

is again possible. This functionality will be managed by wland service running on start up. The

source code for wland service is available via our svn repository at http://svn.visionsystems.de/.

4.2. GSM Support

Using PCI Express Mini Card adapter described in the Hardware Manual you can attach a GSM

card. The system was tested with following GSM/UMTS/HSPA cards:

• MC8775 (Sierra Wireless)

• MC8790/MC8705 (Sierra Wireless)

• F5521gw (Ericsson)

Following conﬁguration ﬁles were prepared to use this functionality:

• /etc/network/interfaces (the PIN for your SIM-card will be conﬁgured there. See comments

in the ﬁle)

• /etc/chatscripts/gprs (your provider’s Access Point Name (APN) is stored here)

• /etc/ppp/peers/gprs
