1027        The the ability of cancelling GATT connections and trying to reconnect
1028        to the same device via a different address.
1029
1030        Steps:
1031        1. A starts advertising
1032        2. B starts scanning and finds A's mac address
1033        3. Stop advertisement from step 1. Start a new advertisement on A and
1034            find the new new mac address, B knows of both old and new address.
1035        4. B1 sends connect request to old address of A
1036        5. B1 cancel connect attempt after 10 seconds
1037        6. B1 sends connect request to new address of A
1038        7. Verify B1 establish connection to A in less than 10 seconds
1039
1040        Expected Result:
1041        Verify that a connection was established only on the second
1042            advertisement's mac address.
