-    @brief  Creates a new 128-bit UUID
-
-    @note   The UUID is a unique 128-bit (16 byte) ID used to identify
-            different service or characteristics on the BLE device.
-
-    @note   When creating a UUID, the constructor will check if all bytes
-            except bytes 2/3 are equal to 0.  If only bytes 2/3 have a
-            value, the UUID will be treated as a short/BLE UUID, and the
-            .type field will be set to UUID::UUID_TYPE_SHORT.  If any
-            of the bytes outside byte 2/3 have a non-zero value, the UUID
-            will be considered a 128-bit ID, and .type will be assigned
-            as UUID::UUID_TYPE_LONG.
-
-    @param[in]  uuid_base
-                The 128-bit (16-byte) UUID value.  For 128-bit values,
-                assign all 16 bytes.  For 16-bit values, assign the
-                16-bits to byte 2 and 3, and leave the rest of the bytes
-                as 0.
