OMAP Wireless Connectivity NLCP WLAN Station WPA Supplicant Configuration file

WLAN Station Configuration Scripts

The following section provides information how to configure the Station to connect to different WiFi network that supports arbitrary security modes.
The configuration will be performed using Terminal connected to the EVM serial port.

The following items will be covered:

1. Connect to non secured WiFi network)
2. Connect to secured WiFi network (WEP)
3. Connect to secured WiFi network (WPA)
4. Connect to secured WiFi network (WPA2)

Hardware Configuration

Following are configuration file content for personal environment Security mode settings.

Connect to non secured WiFi network

Move existing /etc/wpa_supplicant.conf to /etc/wpa_supplicant.conf.bak. Create new /etc/wpa_supplicant.conf with the following configuration, where

ssid is the name of the Access Point we are about to connect to:

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
        key_mgmt=NONE
        ssid="ECS"   #optional
}

Run following command to connect:

root@am37x-evm:/usr/sbin# wpa_supplicant -d -Dnl80211 -c /etc/wpa_supplicant.conf -iwlan0 -B

note: Only one instance of "wpa_supplicant" run only in the system, therefor to modify the security first kiil the wpa_supplicant process and then call the "wpa_supplicant" with the changed configuration file.

Connect to secured WiFi network (WEP)

Move existing /etc/wpa_supplicant.conf to /etc/wpa_supplicant.conf.bak. Create new /etc/wpa_supplicant.conf with the following configuration, where

• ssid is the name of the Access Point we are about to connect to
  
• wep_key(0,1,2,3) is the pre shared key required by the Access Point we are about to connect to. Protocol WEP allows to define a number of possible keys.
  

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
 ssid="Cisco"
  key_mgmt=NONE
  pairwise=NONE
  group=WEP40
  auth_alg=OPEN
  wep_key0=1234567890
  wep_key1=0000000000
  wep_key2=0000000000
  wep_key3=0000000000
}

Run the following commend to connec:

root@am37x-evm:/usr/sbin# wpa_supplicant -d -Dnl80211 -c /etc/wpa_supplicant.conf -iwlan0 -B

note: Only one instance of "wpa_supplicant" run only in the system, therefor to modify the security first kiil the wpa_supplicant process and then call the "wpa_supplicant" with the changed configuration file.

Connect to secured WiFi network (WPA)

Move existing /etc/wpa_supplicant.conf to /etc/wpa_supplicant.conf.bak. Create new /etc/wpa_supplicant.conf with the following configuration, where

• ssid is the name of the Access Point we are about to connect to
  
• psk is the pre shared key required by the Access Point we are about to connect to
  

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
        ssid="Cisco"
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        psk="1234567890"
        priority=2
}

Run the following commend to connect:

root@am37x-evm:/usr/sbin# wpa_supplicant -d -Dnl80211 -c /etc/wpa_supplicant.conf -iwlan0 -B

note: Only one instance of "wpa_supplicant" run only in the system, therefor to modify the security first kiil the wpa_supplicant process and then call the "wpa_supplicant" with the changed configuration file.

Connect to secured WiFi network (WPA2)

Move existing /etc/wpa_supplicant.conf to /etc/wpa_supplicant.conf.bak. Create new /etc/wpa_supplicant.conf with the following configuration, where

• ssid is the name of the Access Point we are about to connect to
  
• psk is the pre shared key required by the Access Point we are about to connect to
  

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
        ssid="Cisco"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        psk="1234567890"
        priority=2
}

Run following command to connect:

root@am37x-evm:/usr/sbin# wpa_supplicant -d -Dnl80211 -c /etc/wpa_supplicant.conf -iwlan0 -B

note: Only one instance of "wpa_supplicant" run only in the system, therefor to modify the security first kiil the wpa_supplicant process and then call the "wpa_supplicant" with the changed configuration file.
