If you have single mode LE device and a dual-mode BR/EDR and LE device then they can only connect and pair using an LE connection using LE Security (see the Bluetooth Specification (Core Spec v 4.0) [Vol 3] Part H, 3.6 Security in Bluetooth Low Energey - Available from www.bluetooth.org - login required).

If you have two dual mode devices then they must connect and pair over BR/EDR even when using GATT and LE profiles, under the current 4.0 specification.

There are changes for the 4.1 version (not yet ratified) that will change that restriction.
