Connecting to a Bluetooth 4.0 LE can be tricky especially on iOS where the real address of devices is hidden behind the generated UUID. This class will help you:

  • discover advertising Bluetooth LE peripherals ( servers ).
  • Connect to a specific device.
  • list available services.
  • read each service characteristics.
  • read available descritors.
  • list allowed permission for read/write.

How to use it

1 - Move class files into your project ( you can use drag-n-drop ) using xCode.

2 - Include BluetoothLEManager class in your ViewController

#import "BlueToothLEManager.h"

3 - declare BluetoothLEManager and intialize it

@interface ViewController ()
@property (strong) BlueToothLEManager *bluetoothManager;

- (void)viewDidLoad {
    [super viewDidLoad];
  // code
    self.bluetoothManager = [[BlueToothLEManager alloc] init];

NOTE: You can use TableView to display the list of devices. the discovered devices are stored in foundDevices Don't forget to set the tableView delegate and source.

- (void)viewDidLoad {
    [super viewDidLoad];
    self.table.delegate = self;
    self.table.dataSource = self;
    self.bluetoothManager = [[BlueToothLEManager alloc] init];
