Hi,

 

What is the best way to generate custom BLE 128 bit UUIDs ?

 

How has ST generated the custom UUIDs in the firmware examples of Sensortile kit related to BLE ? For example, following are some UUIDs(in bold) in one of the firmware example :

 

/* Hardware Characteristics Service */
#define COPY_HW_SENS_W2ST_SERVICE_UUID(uuid_struct)    COPY_UUID_128(uuid_struct,0x00,0x00,0x00,0x00,0x00,0x01,0x11,0xe1,0x9a,0xb4,0x00,0x02,0xa5,0xd5,0xc5,0x1b)
#define COPY_ENVIRONMENTAL_W2ST_CHAR_UUID(uuid_struct) COPY_UUID_128(uuid_struct,0x00,0x00,0x00,0x00,0x00,0x01,0x11,0xe1,0xac,0x36,0x00,0x02,0xa5,0xd5,0xc5,0x1b)

 

Is there a tool available for the same ?

 

Best Regards.
