定义

“GATT层”中定义的所有属性都有一个UUID值，UUID是全球唯一的128位的号码，它用来识别不同的特性。

换算规则

128_bit_value=16_bit_value2^96+Bluetooth_Base_UUID
128_bit_value=32_bit_value2^96+BIuetooth_Base_UUID

Bluetooth_Base_UUID = 00000000-0000-1000-8000-00805F9B34FB

假如16bits的uuid为0x1234,则转换成128bits的uuid是:
0x00001234-0000-1000-8000-00805F9B34FB

假如32bits的uuid是0x12345678,则转换成128bits的uuid是
0x12345678-0000-1000-8000-00805F9B34FB
