The bluetooth 4 0 specification permits devices to implement either or both of the le and br edr systems.

Bluetooth low energy medical devices.

Bluetooth low energy uses the same 2 4 ghz radio frequencies as classic bluetooth. Wireless medical monitoring with bluetooth low energy will initially be targeted at bg measurement but applications such as body temperature blood pressure pulse oximetry and heart rate will follow shortly after. However bluetooth low energy is a new technology and medical products equipped with it are unlikely to appear before 2011. A team of academics from singapore has published this week a research paper detailing a collection of vulnerabilities named sweyntooth that impact devices running the bluetooth low energy ble.
