Manager doesn't scan in a launch daemon

[H-Shafiei]

Hey! I have created a launch daemon and I am using your great classes for managing iPhone's wifi modules. There is a problem though, I am using this tutorial for creating the launch daemons: https://www.chrisalvares.com/blog/7/creating-an-iphone-daemon-part-1/ When I scan for networks the scan callback function isn't called. Do you know why?

again thanks for your great work!

P.S.I think it's because runloops and these stuff but I know almost nothing about them!! :)

I can't really help you if you don't show me your code. :(

Sorry I didn't have internet access so I am answering after 4 days:) Here is what I do

main.m:

int main (int argc, const char * argv[])
{

@autoreleasepool
{
    NSLog(@"\n\n\n MSManagerStarted 01 \n\n\n");

    // insert code here...
    MSManager *server = [[MSManager alloc] init];

    NSDate *now = [[NSDate alloc] init];
    NSTimer *timer = [[NSTimer alloc] initWithFireDate:now
                                              interval:.01
                                                target:server
                                              selector:@selector(start)
                                              userInfo:nil
                                               repeats:NO];

    NSRunLoop *runLoop = [NSRunLoop currentRunLoop];
    [runLoop addTimer:timer forMode:NSDefaultRunLoopMode];
    [runLoop run];
}
return 0;
}

here is MSManager's class start method implementation:

- (void)start
{
       [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(managerDidFinishScanning) name:kDMNetworksManagerDidFinishScanning object:nil];
        [[DMNetworksManager sharedInstance] scan];
}

But after it is scanned nothing happens. I mean 'managerDidFinishScanning' isn't called. Can you help?

[davidmurray]

Maybe try to use CFRunLoopRun() instead of your NSDate, NSTimer and NSRunLoop code?

Also, can you check the syslog? Maybe you're missing an important entitlement.

[H-Shafiei]

There is no problem with the entitlements. Even with CFRunLoopRun() it doesn't work. Any other ideas?

[davidmurray]

Can you add an NSLog at the beginning of DMNetworksManager's _scanDidFinishWithError method?

[H-Shafiei]

Nothing happens. It gets stuck at _scan method Have you ever used this in a launch daemon?

[davidmurray]

Try CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, false). Also, make sure that this is the last thing that your main function does.

[H-Shafiei]

This doesn't work either:( I can solve my problem another way. What I am trying to do is I want to connect to a given network (the ssid and encryption model and password is given). What i used to do was scan for networks and then if the given said network was scanned then i associated with it. Can I do this another way if there is a problem with scanning?

[davidmurray]

I think it's because of the entitlements thing. Can you run ldid -e YourBinary on your daemon? ldidis available in Cydia.

here is the result: `

com.apple.CommCenter.Messages-send com.apple.coretelephony.Identity.get com.apple.developer.ubiquity-container-identifiers com.apple.locationd.preauthorized com.apple.wifi.manager-access keychain-access-groups apple com.apple.preferences com.apple.CommCenter.Messages-send com.apple.coretelephony.Identity.get com.apple.developer.ubiquity-container-identifiers com.apple.locationd.preauthorized com.apple.wifi.manager-access keychain-access-groups apple com.apple.preferences com.apple.CommCenter.Messages-send com.apple.coretelephony.Identity.get com.apple.developer.ubiquity-container-identifiers com.apple.locationd.preauthorized com.apple.wifi.manager-access keychain-access-groups apple com.apple.preferences `

[davidmurray]

Hm, looks correct. No idea then.

[H-Shafiei]

any help with the network association thing? I mean connect to network without scanning.
