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 Please provide the following information. Are you using a TI module? [y/n] : y What is the chip flavor? [1801/1805/1807/1831/1835/1837 or 0 for unknown] : 1831 Should SISO40 support be applied? [y/n] : n The device has been successfully configured. TI Module: y Chip Flavor: 1831 Number of 2.4GHz Antennas Fitted: 1 Number of 5GHz Antennas Fitted: 0 Diversity Support: n SISO40 Support: n Japanese Standards Applied: n root@varsomam33:/usr/bin/wlconf# [ 713.882024] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11) [ 713.909501] wlcore: loaded
For WL1837:
root@varsomam33:/usr/bin/wlconf# ./configure-device.sh Please provide the following information. Are you using a TI module? [y/n] : y What is the chip flavor? [1801/1805/1807/1831/1835/1837 or 0 for unknown] : 1837 Should Japanese standards be applied? [y/n] : n How many 2.4GHz antennas are fitted? [1/2] : 2 How many 5GHz antennas are fitted? [0/1/2] : 2 The device has been successfully configured. TI Module: y Chip Flavor: 1837 Number of 2.4GHz Antennas Fitted: 2 Number of 5GHz Antennas Fitted: 2 Diversity Support: y SISO40 Support: y Japanese Standards Applied: n root@varsomam33:/usr/bin/wlconf# [ 872.471817] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11) [ 872.499145] wlcore: loaded
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
MAC address settings
In order to use the built-in TI unique mac address of the module, change the wl1271-nvs.bin file using the calibrator application:
$ calibrator set nvs_mac /lib/firmware/ti-connectivity/wl1271-nvs.bin 00:00:00:00:00:00 reboot system!
Note: This operation should be done only once
The WLAN MAC addresses for the supported devices are derived as follows:
- BD_ADDR: 08:00:28:00:00:00
- WLAN 1: 08:00:28:00:00:01
- WLAN 2: 08:00:28:00:00:02
When deriving the WLAN addresses from the BD_ADDR, ensure that the organizational unique identifier (OUI) is not changed.
The OUI (first 3 bytes) is pre-assigned by the IEEE to different companies (for example, the TI OUI is 08:00:28). The company that owns the OUI assigns the network identification card (NIC) address (last 3 bytes).
