security: application layer user defined

voice capable: no
power consumption: 0.01 to 0.5W

4, Generic Attribute Profile (GATT).
The Bluetooth SIG have reserved a range of UUIDs (of the form xxxxxxxx-0000-1000-8000-00805F9B34FB [34]) for standard attributes.For efficiency, these identifiers are represented as 16-bit or 32-bit values in the protocol, rather than the 128 bits required for a full UUID. For example, the Device Information service has the short code 0x180A, rather than 0000180A-1000-... . The full list is kept in the Bluetooth Assigned Numbers document online
