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.
