7.8.5 Step 5: Finalize the View Controller File
In the view controller file, perform the following:
• Set delegate and initialize IDT_NEO2 singleton object in the viewDidLoad method. To automatically
connect to BLE, enter the friendly name of the device Reference: Allocate/Initialize IDT_NEO2 Object
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
IDT_NEO2 . sharedController (). delegate = self
IDT_NEO2 . sharedController ().device_setBLEFriendlyName( "VP-2722" ); //set to
device ble name
IDT_NEO2 . sharedController ().device_enableBLEDeviceSearch(nil);
}
