　　Bluetooth Low Energy （BLE） is a part of Bluetooth Ver. 4.0， BT 4.0 covers both BLE as well as BT classic 2.1 and 3.0. If both are implemented in one device it is called dual mode. Dual mode chips implement the low energy specification and may consume just a fraction of the power of classic Bluetooth， allowing the short-range wireless standard to extend to coin cell battery applications Dual mode chips combine low energy with the power of classic Bluetooth and are likely to become a de facto feature in almost all new Bluetooth enabled cellular phones，computers or portable communication nodes. Bluetooth Low Energy （BLE） is not backwards compatible with previous Bluetooth classic standards （2.1+EDR or 3.0）。 Dual mode Bluetooth 4.0 is backwards compatible but is not practical for low power devices but targeted to gateway products
