The following program causes an error.
Please tell me how to resolve.
-------------------------------------------------------------------------------------------
#define BLE_CUS_DEF(_name) static ble_cus_t _name;
NRF_SDH_BLE_OBSERVER(_name ## _obs, BLE_HRS_BLE_OBSERVER_PRIO, ble_cus_on_ble_evt, &_name)

Supplement:
The error doesn't seem to occur in the Mac development environment.

There are a lot of tickets on DevZone describing how to set your own UUID. We also have a detailed tutorial (Custom BLE Service Example) for how to make your own custom service and set your own UUID.

Hi!

Have a look at the list of common characteristic UUID definitions and common service UUID definitions. Is this what you need?

1) The base UUID is defined here

BASE_UUID	00000000-0000-1000-8000-00805F9B34FB

2) Not sure what you mean by "service UUID". Which service are you referring to?

3, 4) Additionally, for status and control characteristics, there are numerous characteristics with "status", such as "Alert Status" and "CGM Status", and the same for "control" characteristics. What is it you mean?

For 5) blood pressure characteristics UUID, the UUID is on the list I linked to. We have a blood pressure application available in nRF5 SDK, so you can see how they set the UUID there.

For 6) PulseWave characteristic, this doesn't seem to be a previously defined one (GATT characteristics) but you can easily make your own characteristic for this.

For adding custom services and characteristics, there are lots of threads on DevZone for how to do this. Take a look at this ticket, for instance.

And finally 7) we have DST Offset 0x2A0D. Is this what you mean?

Best regards,

Heidi
