iOS real device Bluetooth Pairing Request: How to handle popup

i want to handle the Bluetooth Pairing Request popup on iOS real device.
I navigate in the Settings app from the iPhone 6s and enable the Bluetooth via Appium. Just after i start a bluetooth request from a other device to my iPhone the iPhone shows the Pair-Popup. How can i control this popup and tap the Pair Button?. It appears to me that Appium freeze and have no access to the popup. Can someone help me?
