Module rubble::uuid [−][src]
Expand description
BLE UUIDs (16, 32 or 128 bits).
Bluetooth assigns UUIDs to identify services and characteristics. In order to save space, many common UUIDs can be represented and transmitted as 16- or 32-bit aliases instead of the full 128 bits.
The shorter UUIDs can be converted to their full 128-bit counterparts by making use of the
Bluetooth Base UUID, which is defined as 00000000-0000-1000-8000-00805F9B34FB.
A 16-bit UUID alias can be converted to its 32-bit equivalent by zero-extending it: 0xABCD
becomes 0x0000ABCD.
A 32-bit UUID alias can then be converted to its full 128-bit equivalent by placing it in the
first 4 Bytes of the Base UUID. Hence 0x1234ABCD would become
1234ABCD-0000-1000-8000-00805F9B34FB.
