jksoft 0:8468a4403fea 27 @brief Creates a new 128-bit UUID
jksoft 0:8468a4403fea 28
jksoft 0:8468a4403fea 29 @note The UUID is a unique 128-bit (16 byte) ID used to identify
jksoft 0:8468a4403fea 30 different service or characteristics on the BLE device.
jksoft 0:8468a4403fea 31
jksoft 0:8468a4403fea 32 @note When creating a UUID, the constructor will check if all bytes
jksoft 0:8468a4403fea 33 except bytes 2/3 are equal to 0. If only bytes 2/3 have a
jksoft 0:8468a4403fea 34 value, the UUID will be treated as a short/BLE UUID, and the
jksoft 0:8468a4403fea 35 .type field will be set to UUID::UUID_TYPE_SHORT. If any
jksoft 0:8468a4403fea 36 of the bytes outside byte 2/3 have a non-zero value, the UUID
jksoft 0:8468a4403fea 37 will be considered a 128-bit ID, and .type will be assigned
jksoft 0:8468a4403fea 38 as UUID::UUID_TYPE_LONG.
jksoft 0:8468a4403fea 39
jksoft 0:8468a4403fea 40 @param[in] uuid_base
jksoft 0:8468a4403fea 41 The 128-bit (16-byte) UUID value. For 128-bit values,
jksoft 0:8468a4403fea 42 assign all 16 bytes. For 16-bit values, assign the
jksoft 0:8468a4403fea 43 16-bits to byte 2 and 3, and leave the rest of the bytes
jksoft 0:8468a4403fea 44 as 0.
