ok but if I set simple a 128 bit uuid in generator (0x6E400001B5A3F393E0A9E50E24DCCA9E) 

 pzCharacteristicData_t struct still using 16bit value for uuid

typedef struct

    uint16_t svcUUID; // UUID of the service
    uint16_t dataLen; //
    uint8_t paramID; // Index of the characteristic
    uint8_t data[]; // Flexible array member, extended to malloc - sizeof(.)
} spCharacteristicData_t;

and when sending message to main task it simply don't fits 

static void user_NUS_ValueChangeCB(uint16_t connHandle,
                              uint8_t paramID, uint16_t len,

even TI_BASE_UUID_128 macro is getting erro with too large int
