Bluetooth plugin for untiy

Hi, I'm trying to make unity plugin for checking if Bluetooth is on or off on the iPhone/iPad. And I'm kinda stuck halfway.

In my current plugin I just call one method that initializes CBCentralManager and then should check the state of the manager. But nothing happens when I call IsBluetoothEnabled in Unity. Like the delegate isn't being fired. But I do get the alert if I call it manually ([self centralManagerDidUpdateState:self.bluetoothManager] in detectBluetooth method. So calling the plugin and that works. Just not the CBCentralManager I guess..

Edit:
The delegate is beeing called on bluetooth on/off cange, but the state is always unknown. Any ideas?


P.S.: I'm no iOs developer, I snatched this code from stackoverflow.

This is what I have:

Code (CSharp):

1. #import <CoreBluetooth/CoreBluetooth.h>
2.  
3. @interface BluetoothPlugin : UIViewController <CBPeripheralDelegate, CBCentralManagerDelegate>
4. {
5.     CBCentralManager *bluetoothManager;
6. }
7. @property (readwrite, nonatomic) CBCentralManager *bluetoothManager;
8. @end
9.  
10.  
11. @implementation BluetoothPlugin
12.  
13. - (void)detectBluetooth
14. {
15.     if(!self.bluetoothManager)
16.     {
17.         // Put on main queue so we can call UIAlertView from delegate callbacks.
18.         self.bluetoothManager = [[[CBCentralManager alloc] initWithDelegate:self queue:dispatch_get_main_queue()] autorelease];
19.     }
20. }
21.  
22. - (void)centralManagerDidUpdateState:(CBCentralManager *)central
23. {
24.     NSString *stateString = nil;
25.     switch(bluetoothManager.state)
26.     {
27.         case CBCentralManagerStateResetting: stateString = @"The connection with the system service was momentarily lost, update imminent."; break;
28.         case CBCentralManagerStateUnsupported: stateString = @"The platform doesn't support Bluetooth Low Energy."; break;
29.         case CBCentralManagerStateUnauthorized: stateString = @"The app is not authorized to use Bluetooth Low Energy."; break;
30.         case CBCentralManagerStatePoweredOff: stateString = @"Bluetooth is currently powered off."; break;
31.         case CBCentralManagerStatePoweredOn: stateString = @"Bluetooth is currently powered on and available to use."; break;
32.         default: stateString = @"State unknown, update imminent."; break;
33.     }
34.     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Bluetooth state" message:stateString delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil];
35.     [alert show];
36. }
37.  
38. @end
39.  
40. static BluetoothPlugin* delegateObject = nil;
41.  
42. extern "C"
43. {
44.  
45.     bool _IsBluetoothEnabled()
46.     {
47.         if (delegateObject == nil)
48.             delegateObject = [BluetoothPlugin alloc];
49.         [delegateObject detectBluetooth];
50.  
51.     }
52.  
53. }

 

Old post but in centralManagerDidUpdateState you need to call self.bluetoothManager instead of bluetoothManager, take out line 5 up there, and I had to remove autorelease because I was using ARC.
