How to fetch properties or name of paired two or more BlueTooth keyboards (Belkin keypad..)

I am creating a simple test project in that only label is present. Two Bluetooth keyboards (Belkin keypad)is connected to iPad. I want to find each device name or any properties or any unique path of those devices that I can show its name when pressing any key from pin pad. I want to find input come from which device. I tried using core Bluetooth but it only shows peripherals not showing my Bluetooth keypad name.I also search IOBluetooth but it is for macOS. I require to use it in iOS swift. kindly help me .

tried this way...

//Using External accessory

import UIKit

import ExternalAccessory

class ViewController: UIViewController 

{

@IBOutlet weak var tableView: UITableView!

var manager = EAAccessoryManager.shared()

override func viewDidLoad() {
     super.viewDidLoad()

     let a = manager.connectedAccessories.count
     print(a)// print 0

NotificationCenter.default.addObserver(self, selector: #selector(deviceConnected), name: NSNotification.Name.EAAccessoryDidConnect, object: nil)

}

@objc func deviceConnected(notification: NSNotification) 

{

 if let acc = notification.userInfo![EAAccessoryKey] 
{
showAccessoryInfo(accessory: acc as! EAAccessory)
print("Connected:", acc)
      }
   tableView.reloadData()
  }

 func showAccessoryInfo(accessory: EAAccessory) 
   {
 print("title\(accessory.manufacturer) and name :\(accessory.name) and message \(accessory.description)")
    }


 func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
    }

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return manager.connectedAccessories.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
         print("10")
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
      let acc = manager.connectedAccessories[indexPath.row]
              cell.textLabel?.text = "\(acc.manufacturer) \(acc.name)"
              cell.detailTextLabel?.text = "\(acc.modelNumber) \(acc.serialNumber)\n fr:\(acc.firmwareRevision) hr: \(acc.hardwareRevision)"
         print("11")
      return cell
}
func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {
      let acc = manager.connectedAccessories[indexPath.row]
    showAccessoryInfo(accessory: acc)
         print("12")
}


}

You can use EAAccessoryManager.shared().connectedAccessories for getting connected devices.

Check if the returned EAAccessory has what you need
