Changing UUID number for service and characteristic

[Shimon_nohayo]

Hi,

SDK16

I'm using ble_cus.c to define custom BLE service.

In the ble_cus.h file the definition of the UUID is 

#define CUSTOM_SERVICE_UUID_BASE {0xBC, 0x8A, 0xBF, 0x45, 0xCA, 0x05, 0x50, 0xBA, \
                                                                      0x40, 0x42, 0xB0, 0x02, 0xC9, 0xAD, 0x64, 0xF4}

#define CUSTOM_SERVICE_UUID         0x1520
#define CUSTOM_VALUE_CHAR_UUID 0x1521

and I need the UUID to be:

    Unknown characteristic to 0001 0203-0405-06-07-08-09-0a0b 0c0d 2b10·  
    Unknown service to           0001 0203-0405-06-07-08-09-0a0b 0c0d 1910  

Please advise how can modify the UUID so the service UUID and characteristic  UUID will be as required?

BR,

Shimon

Hi,

I think this is explained pretty good in our service and characteristics tutorial. 

See step 3 in the service and  step 2.A in the characteristics tutorial.

Hi 

I understand this tutorial,

I want that the Service and Characteristics 16 bit UUID will be in the last 16bit of the base UUID

Hi,

The placement of the service and characteristics UUID is determined by the Bluetooth Low Energy specification. It will therefore always be placed after the first two bytes of the base UUID.
