A BT-LE device cannot talk with a non-BT-LE (say "classic" Bluetooth)
device. There are many differences in the protocol stacks, as for example
in the PHY and Link layers.

However, a dual-mode device (i.e. a device that supports both "classic"
Bluetooth and BT-LE) can benefit from the fact that many elements already
present in classic Bluetooth can be reused in a BT-LE implementation.

BT-LE was designed from the basis of "classic" Bluetooth for optimized
operation in control and monitoring applications, which typically involve
devices that exhibit constraints (in energy supply, processing power,
memory, etc.).

For more details about all this, you may refer to the Bluetooth specs.
They are publicly available.
