Porting a WiFi Driver on a android supported platform

[Maneesh]

Hi

I have to port a Wi-Fi driver on Android supported platform.

can you somebody tell me, the steps to follow the porting a WiFi
driver on android.

Is this any tools require if yes please let me know.

[vinay]

muneesh,

 

First verify your drivers are getting inserted and you are able to connect AP with static Ip adress (use wlan_cfg). This is independent of Android and it should work FIRST.

 

1. Add HAVE_CUSTOM_WIFI_DRIVER_2 := true to build/target/board/generic/BoardConfig.mk file.

 

2. make sure external/wpa_supplicant/.config has got below entries

CONFIG_WIRELESS_EXTENSION=y
CONFIG_CTRL_IFACE=y
CONFIG_DRIVER_WEXT=y

3. Build android with this you will get support for WEXt and wpa_supplicant client.

 

4. After the system boot, insert driver and know the interface (in my case it is eth1)

 

5. Modify wpa_supplicant.conf file for AP configuration and Run 

/system/bin/wpa_supplicant -Dwext -ieth1 -c/sdcard/wpa_supplicant.conf 

 

5. Run dhcp to get the IP

/system/bin/dhcpcd -d eth1

 

6. Ping to AP to check connectivity.

Hi vinay:
I had meet a question about wifi in android.
I had suceessful to insmod my wifi driver but the wifi not up yet.
when I typed "netcfg wlan0 up", I got the some error.

# ifconfig wlan0 up
firmware: requesting zd1211/zd1211b_ub
init: untracked pid 2425 exited
usb 1-7.3: Could not load firmware file zd1211/zd1211b_ub. Error

zd1211rw 1-7.3:1.0: couldn't load firmware. Error number -2
error: SIOCSIFFLAGS (No such file or directory)

Could you give me some suggestion?
Sorry to trouble you.
Thanks in advance.

Please check your firmware file location. 

It must be located under /etc/firmware/* (= /system/etc/firmware/*)

Hi vinay

I'd like to know the detail description of wpa_supplicant.conf.

I would be grateful for your support.

I have a similar setup. My wifi shows up as eth1. I tried to follow
your instructions, did not quite work. So I am able to load
wpa_supplicant, can connect to AP, can ping and wget files from web.
My system does not resolve domain names for some reason. What do I
need to have DNS working? But the biggest concern is that despite the
fact I can download files from internet, android does not see my wifi.
UI says "unable to start wifi", and log has "E/WifiService( 601):
Failed to load Wi-Fi driver." How do I actually make android's wifi
friends with my driver that is underneath eth1?

I am getting the following error.

D/WifiService( 2436): Unable to open connection to supplicant on "/
data/system/wpa_supplicant/wlan0" Permisiion Denied.

[mvniekerk]

Hi SH
Make sure that all the correct directories is in the right place
(google for /data/misc wifi android)
Search through all the android code and make sure that tiwlan0 is
changed to whatever your wifi device's name is.

That will save you considerable time...

[ehun...@gmail.com]

Hi everyone:
I have a question about wpa_supplicant. I hope someone can offer some
suggestion for me.
I have successful load driver and firmware file in android.
But I have problem at wpa_supplicant.

In you supplicant conf file.. try mentioning..

ctrl_interface=DIR=/data/system/wpa_supplicant/ GROUP=system

By default the permission of the socket would be root and the service
running on behalf of system won't b able to access it.

[SH]

Thank you for your advices .

I've got it solved.

but next error below:

V/WifiStateTracker( 2422): Changing supplicant state: INACTIVE ==>

I don't know why Changing supplicant state of wpa_supplicant. is
INACTIVE.

[Androidphan]

I'm getting the following error at the moment:
D/WifiHW ( 2325): Unable to open connection to supplicant on "/data/
system/wpa_supplicant/wlan0": No such file or directory

I got wpa_supplicant running.

So it exists.

Why is this??

Hi,

Hi, test you wifi connection using the wpa_cli program. The parse
function of the
scan result expect a - to the signal stregh (if I remember) to parse the
result, otherwise
fail.

wpa_cli has an interractive mode to operate, and you can send command like:
scan and scan-results.

Hi Nail,

You mentioned that you are connected. What does it mean you are connected?
Did you get an IP address or are you attached to the AP (you should be able
to see the SSID)?

Try first to find out on the AP whether it can see you.

Dear Roman

yes, i got IP and can connect to network,

it is because i have configred the wpa_supplicant.conf, and the
contents is shown below:

wpa_supplicant.conf:
===============================================================
update_config=1
eapol_version=1
ap_scan=1 # ap_scan=1: wpa_supplicant initiates scanning and AP
selection
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
}

===============================================================

so, it will do all things needed automatically,

could you please help me to find out where to get the SSID ?

I have a problem with Wifi that it's not showing any scan results in
the GUI.
Anyone patched that problem already? I think it's the parseresults
function.

[Roman Baumgaertner]

Nail,

I don't understand your question. If you are connected you should see with
the command iwconfig to which SSID you are attached to.

It might make sense to send the detail configuration of your supplicant to
find out what is going on. Make sure that you have nowhere a typo in your
configuration files.

[nail]

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

Hi Nail,

Here is an article which might help

http://w1.fi/wpa_supplicant//devel/driver_wrapper.html

Of course you still have to find out how to hook up your code exactly
to the Android wifi support.

Have you tried already to install a common Linux Wifi supplicant on
your board?

--Roman

[nail]

Dear Roman,

two weeks ago, i try to build common wpa_supplicant into normal linux
OS,

but i failed to build wpa_supplicant。

thank you for your hint, and i will keep working on this topic :-)

dear Roman,

i found the wlan interface which wpa_supplicant create is locate at
root dir, i.e. /wlan0,

so, i try to use "wpa_cli -p /wlan0", it can connect to
wpa_supplicant :-)

next step i need to let android wifi UI has the same behavior as
wpa_cli command,

i modify some code of "Framework/base/services/java/com/android/server/
Wifiservice.java
" and "hardware/libhardware_legacy/wifi/wifi.c",

after execute, i got following error:

"D/WifiHW ( 2127): Unable to open connection to supplicant on "/
wlan0": Connection refused",

i think this is some kind of "permission deny", and the user:group of /
waln0 is root:wifi,

do you have any idea about this issue :-(

In the supplicant conf file you can put GROUP=system . This will
create sockets with permission for "system".

Thanks,

Hello Nail,

Sorry for the late response. I took some vacation .... I am not sure exactly
in which order you are trying to port the Wifi to your device.

In general I would recommend to make sure that your needed functionality is
running on native before you do any integration on Java level.

You might want to check in the Wifi native code in which cases (if not done
yet) the error " Unable to open connection to supplicant on" is reported.

Please, keep me updated about your progress.

Thx,
Roman
