Why my LinkIt got 3 addresses ?

And two of them are identical . :confused: :question:

That sound strange, maybe the second one is correct.

Yes , I tried all addresses , the second one (2C:F7:F1:81:22:3E) is connectable , but others are not , then I searched “My_BTServer” in the system’s built-in Bluetooth interface of my Phone , there is phone-like icon in front of “Cf:02:60:C9:3F:D4” , but “2C:F7:F1:81:22:3E” . So I wondered if “Cf:02:60:C9:3F:D4” is a address for WiFi , for WiFi and Bluetooth use the same antenna … (What a ridiculous estimate) =_=
