VAR-SOM-AM33 Wireless LAN

WiLink WLAN module configuration

VAR-SOM-AM33 V2.X only:
When using VAR-SOM-AM33 v2.x, SOM has a WL183x module. In that case you should configure the WL183x module as follows (only in the first boot):

$ cd /usr/bin/wlconf/
$ ./configure-device.sh
Then choose the correct number of module and antennas on board


For example for WL1831:

root@varsomam33:/usr/bin/wlconf# ./configure-device.sh

General usage

List SSIDs, from Linux shell type:

$ ifconfig wlan0 up
$ iw wlan0 scan

Connecting to an encrypted network:

Find your network from the above scan command.

$ wpa_passphrase <YourAP> <YourPassword> >wpa.conf
$ ps | grep wpa_supplicant
*kill the wpa_supplicant process if exist.
$ wpa_supplicant -Dnl80211 -iwlan0 -c./wpa.conf -B
$ udhcpc -iwlan0
$ ifconfig

• WL12xx calibration tool

Calibration of TI WL12xx wireless device is required and is saved into the NVS file. The NVS file is then used by the wl12xx driver. For more details please read NLCP Calibration Process

First time need to set mac address to be used automatically

$ calibrator set nvs_mac /lib/firmware/ti-connectivity/wl1271-nvs.bin 00:00:00:00:00:00
