Apple80211Associate method signature
GoogleCodeExporter opened this issue · comments
Hi,
I had to associate my iPhone to a given SSID, so I reverse engineered the
associate function:
int Apple80211Associate(struct Apple80211 *handle, CFDictionaryRef *network,
CFString *wpa_key);
handle: An open handle from an Apple80211Open call, that has also been bound to
an interface using
Apple80211BindToInterface.
network: one of the CFDictionaryRefs returned by the Apple80211Scan function.
wpa_key: NSString containing the WPA PSK.
Hopes that helps,
Renault

Hi Ranult,
I am also trying to use the same Apple80211Associate using its address(pointer)
to
associae to unsecure AP,I am passing the same dictionary as the secone argument
returned by the scan. But the function fails with error code 9.
Were you able to associte using this function. If YES could you please help me
outif
I'm missing anything.
Thanks
Raj

Hi Renault,
I would like to join a special SSID but do not know how?
Could you explain me how you managed to do so?
I was wondering if there exist Wifi libraries for IPhone that offer functions
such
Access Point scanning, association....
Actually, I would like to store my credentials (login/password) on the IPhone
and to
log automatically on an HTML authentication based Access Point. I
I tried to search on the web, especially on apple website but I did not find
anything...
I really need some help!
Thanks

can you post the code snippet?
Original comment by renault....@gmail.com on 16 Apr 2009 at 6:49
Hmm ... I've got everything working *except* associating with a network in 3.0.
I'm getting a -101 result--??

Russmcb, you are too nearer the goal.
first confirm that you are passing single network(access point) data as network
parameter and password(if it is WPA/WAP network) in 3rd parameter else nil.
Original comment by tso...@gmail.com on 28 Aug 2009 at 4:14
Should've posted some time ago that the 3rd parameter must be nil, not an empty
string. Had this working for
some time. Thanks, though!

Has anyone been able to use Apple80211Associate on 3.1.*?
It doesn't work for me and I'm at a loss as to why. I get all kinds of error
codes:
9, -4, -101 but never 0 and I have no indication that it worked at all.
I've tried both with a network without encryption and one with encryption.
Also, is this a blocking call? Or does it trigger an asynchronous task that
fires a
notification when done? If so, what notification is raised?
Thanks!

Hi, the Apple80211Associate is still working (at least on 3.1.2). Between the
iPhone OS 2 and 3, the framework has changed name, so you should bind your
functions as following:
void *airportHandle;
int (*Apple80211Open)(void *);
int (*Apple80211BindToInterface)(void *, NSString *);
int (*Apple80211Close)(void *);
int (*Apple80211Info)(void *, NSDictionary**);
int (*Apple80211Associate)(void *, NSDictionary*, void *);
int (*Apple80211Scan)(void *, NSArray **, void *);
libHandle =
dlopen("/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager",
RTLD_LAZY);
Apple80211Open = dlsym(libHandle, "Apple80211Open");
Apple80211BindToInterface = dlsym(libHandle, "Apple80211BindToInterface");
Apple80211Scan = dlsym(libHandle, "Apple80211Scan");
Apple80211Close = dlsym(libHandle, "Apple80211Close");
Apple80211Info = dlsym(libHandle,
"Apple80211GetInfoCopy");
Apple80211Associate = dlsym(libHandle,
"Apple80211Associate");
The most significant change from v2 to v3 is SCAN_RSSI_THRESHOLD parameter
(used for the scan function). It use to take a positive number, far from the
physical dB it should have been
and now it takes the dB of the signal. If you make use of it, you can set it to
-100:
Here is a code snipped (cherry picked from my code, so untested as is):
void *airportHandle;
NSArray *keys = [NSArray arrayWithObjects:@"SCAN_RSSI_THRESHOLD", @"SSID_STR",
nil];
NSArray *objects = [NSArray arrayWithObjects:[NSNumber numberWithInt:-100],
ssid, nil];
NSDictionary *params = [NSDictionary dictionaryWithObjects:objects
forKeys:keys];
NSArray *found;
int openResult = Apple80211Open(&airportHandle);
NSLog(@"Openning wifi interface %@", (openResult == 0?@"succeeded":@"failed"));
int bindResult = Apple80211BindToInterface(airportHandle, @IF_NAME);
int scanResult = Apple80211Scan(airportHandle, &found, params);
NSDictionary *network;
// get the first network found
network = [found objectAtIndex:0];
int associateResult = Apple80211Associate(airportHandle, network,NULL);
Apple80211Close(airportHandle);
Hope that's helps,
Renault

Hey thanks for the quick and detailed answer Renault.
Got it working now :-)
One extra question: is there a way to know when the association is complete?
Following the call, the OS pops up
the Wifi network selection dialog and I'd like to wait until the user has
dismissed this dialog before attempting to
connect to a host. Do you know if some notification is raised to signal that?
Thanks a bunch

Deal all,
when i try to use the framework, the following error happened, could you please
tell me what shall i do?
dlopen(/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager, 1):
image not found
my simulator is OS 3.1.3. thanks a lot.
Original comment by ToLiB...@gmail.com on 29 Mar 2010 at 1:38
Anyone have an explanation on the return values yet? I can associate with my
network using the WPA key. But
sometimes it fails, giving me either a return value of -6 or 16
Original comment by iwha...@gmail.com on 6 Apr 2010 at 3:26
@ToLiBing: this only works on the actual device, not on the Simulator.

How are things working in OS 4.0?
Original comment by russ...@gmail.com on 30 Jun 2010 at 7:03
My App still works, so I guess nothing changed since 3.1.3

How can I detect signal strenght and other information of nearby bluetooth
devices ?
Will applications that use these libraries be allowed on the itunes store ?

Can you connect between two iphones via bluetooth over iOS4?
Original comment by lertl...@gmail.com on 29 Jul 2010 at 9:19
I'm not sure if it's possible using this method. BUT Apple allows
iPhone-to-iPhone communication over bluetooth in the GameKit Framework:

Hi guys,
I have just started to make a iPhone Wifi scanning app. I have searched a lot
websites, finally I have the recent code the below. Someone told this is
working for iPhoneOS4.0 well.
libHandle =
dlopen("/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager",
RTLD_LAZY);
open = dlsym(libHandle, "Apple80211Open");
bind = dlsym(libHandle, "Apple80211BindToInterface");
close = dlsym(libHandle, "Apple80211Close");
scan = dlsym(libHandle, "Apple80211Scan");
But, I have the below warnings.
warning: Unable to read symbols for
"/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0.1/Symbols/usr/lib/libp
cap.A.dylib" (file not found).
warning: Unable to read symbols for
"/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0.1/Symbols/System/Libra
ry/SystemConfiguration/WiFiManager.bundle/WiFiManager" (file not found).
I am using xcode_3.2.3_and_ios_sdk_4.0.1 and iPhone 3G device that jailbroken,
unlocked and updated to 4.0.1.
I know, if I use a private API, can not service and get a risks, but I should
do that. If you any clue about this, please let me know.
Thanks.

This code does not work on the simulator, only on the device. Try to run your
code on the iPhone directly.

I have tried it on he device. but the same. The device is jailbroken, unlocked
and updated to 4.0.1.
Original comment by kikyoung...@gmail.com on 11 Aug 2010 at 2:06
What are the errors when you run on the device? because the errors you pasted
are from the simulator.
Original comment by iwha...@gmail.com on 11 Aug 2010 at 2:40
Thank you for your reply, the code is working fine, I can ignore the warning.
Thanks.
Does anybody know about the error codes of associate? What is the meaning of
-101 and others?

I am having a problem connecting to unsecured networks. My app will connect
fine to my WEP network, but I get a -3900 error when I try to connect to a
network without a password. I have tried sending both an empty string and nil
for the third parameter, but neither worked

Does anyone here know how to get the IP Address after associated.
Original comment by kikyoung...@gmail.com on 2 Sep 2010 at 4:51

When I associate to hotspot, it is just associated, not connected to the
hotspot access point. After associated, how can I make it connected?
After associated, If I open a browser, the browser make it connected. So, I
think, the browser do something, but I do not know the something. ^^;;;;

Hi Renault
Which tools have you used to reverse engineered Apple80211Associate? could you
describe the process to me please? my email is: jibrilg@gmail.com.

Hi, Renault,
Do you have any idea how I can detect the signal strenghts of several access
points? I will need it for an academic test, thanks very much!
Original comment by zhyu...@gmail.com on 30 Sep 2010 at 4:20
Hi Zhyujjh (is it your name or an acronym?)
You have to use the scan function. If this function call is successful, it will
return in the variable "CFArrayRef *list" the list of all available networks
(it is a list of NSDictionary). Iterate over this array and extract the RSSI
key, from the dictionary.
I hope it helps,
Renault

Does anyone know how to toggle the Wifi on an off? On the desktop library, at

Dear All,
I am currently looking for making an app for iPhone that scans for a particular

Could anyone please help me.
I tried above solutions but its not working. I am not getting where to start
from.
Any suggestions?
