Tool/software: Linux
Hello,
I am working on am3354 based custom board and we are using beaglebone black BSP.
I am using ti-processor-sdk-linux-am335x-evm-04.01.00.06 SDK.
on my board i am using wlan3.and i am able to scan the SSID of the wifi and able to connect if SSID dont't have password.
for scanning i am using
iw wlan0 scan | grep SSID
for connect
iw dev wlan0 connect SSID
it is connected.
but i want to integrae the SSID and password in wpa-suplicant for auto connect. but i am not able to connect.
my Interface file is
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
wpa-driver wext << here i tried nl80211 also
wpa-conf /etc/wpa_supplicant.conf
#iface tiwlan0 inet dhcp

wpa-supplicant file
===============
##### wpa_supplicant configuration file template #####
#
# This option can be used to allow wpa_supplicant to overwrite configuration
# file whenever configuration is changed (e.g., new network block is added with
# wpa_cli or wpa_gui, or a password is changed). This is required for
# wpa_cli/wpa_gui to be able to store the configuration changes permanently.
# Please note that overwriting configuration file will remove the comments from
# it.

ctrl_interface_group=1
# IEEE 802.1X/EAPOL version
# wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
# EAPOL version 2. However, there are many APs that do not handle the new
# version number correctly (they seem to drop the frames completely). In order
# to make wpa_supplicant interoperate with these APs, the version number is set
# to 1 by default. This configuration value can be used to set it to the new
# version (2).
eapol_version=1
# AP scanning/selection
# By default, wpa_supplicant requests driver to perform AP scanning and then
# uses the scan results to select a suitable AP. Another alternative is to
# allow the driver to take care of AP scanning and selection and use
# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
# information from the driver.
# 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to
# the currently enabled networks are found, a new network (IBSS or AP mode
# operation) may be initialized (if configured) (default)
# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
# parameters (e.g., WPA IE generation); this mode can also be used with
# non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
# APs (i.e., external program needs to control association). This mode must
# also be used when using wired Ethernet drivers.
# 2: like 0, but associate with APs using security policy and SSID (but not
# BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
# enable operation with hidden SSIDs and optimized roaming; in this mode,
# the network blocks in the configuration file are tried one by one until
# the driver reports successful association; each network block should have
# explicit security policy (i.e., only one option in the lists) for
# key_mgmt, pairwise, group, proto variables
# When using IBSS or AP mode, ap_scan=2 mode can force the new network to be
# created immediately regardless of scan results. ap_scan=1 mode will first try
# to scan for existing networks and only if no matches with the enabled
# networks are found, a new IBSS or AP mode network is created.

# EAP fast re-authentication

kindly suggest me where i am doing wrong configuration.
