dear Roman,
sorry for i have not explain my question enough, and i will be glade
to explain it again:
my goal is to enable the "intel 3945 abg" wifi component on our x86
target platform
so my first step is to enable corresponding kernel config and built-in
corresponding firmware
my next step is trying to build wpa_xxx utility into android to
support wifi setting,
these utility include wpa_cli, wpa_supplicant, ... , etc.
after that, i try to config wpa_supplicant.conf, and all the contents
are shown below:
=====================================================================
wpa_supplicant.conf
update_config=1
ctrl_interface=wlan0
eapol_version=1
# ap_scan=1: wpa_supplicant initiates scanning and AP select
ap_scan=1
fast_reauth=1
network={
ssid="simple"
psk="very secret passphrase"
priority=5
}
# Wildcard match for SSID (plaintext APs only).
#This example selects any
# open AP regardless of its SSID.
network={
key_mgmt=NONE
}
===========================================================================
and I enable wifi using the following command written in
init.rc:
=======================================================
"mkdir /data/misc/wifi 0770 wifi wifi
mkdir /data/misc/wifi/sockets 0770 wifi wifi
mkdir /data/system/wpa_supplicant 0770 wifi wifi
mkdir /data/misc/dhcp 0770 dhcp dhcp
chown dhcp dhcp /data/misc/dhcp
ifup wlan0
service wpa_supplicant /system/bin/logwrapper /system/bin/
wpa_supplicant -iwlan0 -c/system/etc/wifi/wpa_supplicant.conf -dd
group wifi
service wlan_dhcpcd /system/bin/dhcpcd wlan0 "
===================================================================
after all steps, i can connect to the newwork , and get IP
but i don't know which AP the wifi has connected, it is
configured automatically.
although wifi has connected, but the "setting wifi" section in the
android UI
does not know this inform, i.e. i can not enable wifi selection on
android UI
so, my next step is to let android UI knows that the wifi
has enabled, i.e. i need to connect upper and below together
BTW, when i type iwconfig, it shows: not found
thank you for your help
