New page

CL-SOM-iMX7 features 802.11b/g/n wireless connectivity solution, implemented with a TI WiLink8 Combo module.

==== WiFi Initialization ====
* WiFi requires no user interaction for being configured. The driver gets loaded automatically.
Make sure that the WiFi driver is loaded:
<pre>
root@cl-som-imx7-sid:~# lsmod | grep wl18xx
wl18xx 70950 0
</pre>
The WiFi driver can be loaded manually:
<pre>
root@cl-som-imx7-sid:~# modprobe wl18xx
wlcore: ERROR could not get configuration binary ti-connectivity/wl18xx-conf.bin: -2
wlcore: WARNING falling back to default config
wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11)
wlcore: loaded
</pre>
* {{cmd|iwconfig}} command from {{cmd|wireless-tools}} package can be used to retrieve detailed information about the WiFi interfaces:
<pre>
root@cl-som-imx7-sid:~# iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
</pre>
* Activate the interface:
<pre>
root@cl-som-imx7-sid:~# ifconfig wlan0 up
</pre>
* Sample WiFi scanning:
<pre>
root@cl-som-imx7-sid:~# iwlist wlan0 scan
</pre>
The output will show the list of Access Points and Ad-Hoc cells in range.
For more information about connecting to wireless networks and tuning WiFi interfaces refer to “wpa_supplicant” and “wireless-tools” man pages.

==== wpa_supplicant ====
* Configuration sample
{{cmd|wpa_supplicant}} requires a configuration file to be created in order to get connected to a scanned wireless network.<br>
Make use of the example bellow and put the network name and the password into the "ssid/psk" fields.

<pre>
root@cl-som-imx7-sid:~# cat << eof > /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant

network={
ssid="wireless_network_name"
key_mgmt=WPA-PSK
psk="wireless_network_password"
}
eof
</pre>
* Sample run
<pre>
root@cl-som-imx7-sid:~# ifconfig wlan0 up
root@cl-som-imx7-sid:~# wpa_supplicant -B -Dwext -c /etc/wpa_supplicant.conf -i wlan0
root@cl-som-imx7-sid:~# dhclient wlan0
</pre>
