      {
          self.connectingPeripheral = peripheral;        
          NSLog(@&quot;@@@@@@Peripheral Name is:%@ Identifier:%@ Services:%@&quot;,peripheral.name,peripheral.identifier,peripheral.services);
          [self.bluetoothManager connectPeripheral: self.connectingPeripheraloptions: nil];
