VAR-SOM-MX6 - Wireless LAN
Test
Scan for wireless networks:
$ ifconfig wlan0 up $ iw dev wlan0 scan | grep SSID
Connecting to a WPA encrypted network:
Find your network from the above scan command.
$ mv /etc/wpa_supplicant.conf /etc/wpa_supplicant.conf.org $ wpa_passphrase <YourAP> <YourPassword> >/etc/wpa_supplicant.conf $ wpa_supplicant -B -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf
wait for:
wlcore: Association completed.
Disable eth0:
$ ifconfig eth0 down
Run DHCP:
$ udhcpc -iwlan0 $ ifconfig

Access Point
This example will demonstrate you how to use the VAR-SOM-MX6 as an access point. It will forward packets from wlan0 to eth0. DHCPD:
$ vi /etc/udhcpd.conf # Sample udhcpd configuration file (/etc/udhcpd.conf) # The start and end of the IP lease block start 192.168.5.20 #default: 192.168.0.20 end 192.168.5.25 #default: 192.168.0.254 # The interface that udhcpd will use interface wlan0 #default: eth0 #Example opt dns 8.8.8.8 8.8.4.4 # public google dns servers option subnet 255.255.255.0 opt router 192.168.5.1 option lease 864000 # 10 days of seconds
This is a network example. You need to set the IP address based on your network.
First ensure that wpa_supplicant is not holding the device
$ killall wpa_supplicant
IP Forwarding:
$ echo 1 > /proc/sys/net/ipv4/ip_forward $ ifconfig wlan0 192.168.5.1 $ hostapd -B /etc/hostapd.conf -P /var/run/hostapd.pid $ udhcpd /etc/udhcpd.conf $ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
As a next step one should take a look at /etc/hostapd.conf. You may want to configure password access point name etc.
Setup
This phase is not required by default. VAR-SOM-MX6 V2.X (WiLink8):
- Select your WL183x p/n:
$ cd /usr/bin/wlconf/ $ ./configure-device.sh wl18xx select one out of : WL1831, WL1833, WL1835, WL1837.
As a result some additional information may be required like 1/2 antenna connected
<reboot system!>
note: In Yocto Dizzy, ignore the following
wl1271_sdio: probe of mmc2:0001:1 failed with error -110 wl1271_sdio: probe of mmc2:0001:2 failed with error -110
First time need to set mac address to be used automatically (Not required in Yocto Dizzy)
$ calibrator set nvs_mac /lib/firmware/ti-connectivity/wl1271-nvs.bin 00:00:00:00:00:00
