Auto-connect to phone

[DanikV]

Hello, I want to create a device, that can auto-connect to my phone and only my.

I thought to do it by filtering the MAC address.

But as far as I understand iPhone and Android can change their MAC address.

1) I need that device can be connected to the phone via the settings menu on a phone without application.

2) When a phone sees my device it can auto-connect to it.

3) Phone can filter devices by MAC address for example.

Can you help me how to implement it?

I found the HID Keyboard example of what do auto-connect via settings, but after forgetting the device via settings from the phone (iPhone) I can not connect again to the device.
