We are both wrong, read the last sentence for dual mode devices.

>From Bluetooth SPEC(page 1744):

BR/EDR/LE OPERATION MODES AND PROCEDURE
13.1.1.2 Discoverable Mode
...
A device supporting both BR/EDR and LE physical links shall expose the
capabilities of both physical links by performing the following steps:
a) The âLE Supported (Controller)â and âLE Supported (Host)â bits in
the LMP features shall be set as defined in [Vol. 2], Part C Section
3.2.
b) The âBR/EDR Not Supportedâ bit in the Flags AD type shall be set to
â0â as defined in Section 18.1.
c) The âSimultaneous LE and BR/EDR to Same Device Capable
(Controller)â and âSimultaneous LE and BR/EDR to Same Device Capable
(Host)â bits in the Flags AD type shall be set to â0â as defined in
Section 18.1

"le" will be removed. Thanks!
