Several services/characteristics don't work

[ashmanov]

Hello!
In short, I have noble (thank you for your work, by the way) on linux with BlueZ 4.101.
My iPad app tries to find characteristics from linux peripheral. It works in case of only one service and one characteristic. When I add one more, it fails to find any services (though the app finds the peripheral).

I've also described my problem here (and pasted my code): http://stackoverflow.com/questions/24925795/bluetooth-le-on-ios-cannot-work-with-many-services-and-characteristics

I wish you can help me, because I have no idea what to do.

P.S. I've tested my .js code with LightBlue on my Mac - it works. And gatttool also finds all the needed characteristics. And nRF Master also. However, LightBlue on iPad finds nothing (the iPad has Bluetooth 4.0 support and runs the latest iOS 7 version).

@ashmanov I can't seem to find a link to your bleno code from the stackoverflow post (only iOS and dubs) ... I can try it it out on my Linux PC with an iOS, once you share it.

Have you tried toggling bluetooth off/on on you iPad, it caches services/characteristics, the cache is reset when bluetooth is reset.

[ashmanov]

Oops, forgot to share bleno code.

You need to launch test in 'tests' folder.

[ashmanov]

Yes, I've tried it, it didn't help.

Works for me on Linux PC + iPhone with LightBlue:

That's good. Can you please try it with the iOS app? When I launch it, it finds the service, but fails to find any characteristic.

Works for me ... had to remove the dependency for VK-ios-sdk though.

My app delegate is:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    _client = [[WCNBluetoothClient alloc] init];

    [_client connect];
    return YES;
}

Thank you! It is strange and awesome.
What linux version and what bluez, nodejs do you use? And iPhone&iOS?

[ashmanov]

I've tried my code on Ubuntu 14.04 instead of OpenSuse 13.1, and it works!

[sandeepmistry]

Nice! Which version of BlueZ does OpenSuse 13.1 use? I was using Ubuntu 13.10 with BlueZ 4.10 ... can we close this issue?

[sandeepmistry]

Issue resolved, closing.
