API reference for NEO2
Call the Singleton instance of the IDT_NEO2 framework object:

A Singleton instance has been established in the IDT_NEO2 class. To utilize the delegate protocols, best practices would be initialize the connection by setting the delegate with the singleton instance.

To enable scanning for a NEO2 with Bluetooth Low Energy capabilities, you need to execute device_enableBLEDeviceSearch: (IDT_NEO2) identifier:().

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[IDT_NEO2 sharedController] setDelegate:self];
[[IDT_NEO2 sharedController] device_enableBLEDeviceSearch:nil];
}
