How can I add a UUid?

[weiqifa]

When we add a uuid will follow the steps below

err_code = sd_ble_uuid_vs_add(&nus_base_uuid, &p_nus->uuid_type);

// Add the service.
err_code = sd_ble_gatts_service_add(BLE_GATTS_SRVC_TYPE_PRIMARY,
                                    &ble_uuid,
                                    &p_nus->service_handle);

 return sd_ble_gatts_characteristic_add(p_nus->service_handle,
                                       &char_md,
                                       &attr_char_value,
                                       &p_nus->rx_handles);

Your steps seem to be correct.

• Which error codes does sd_ble_gatts_service_add(..) and sd_ble_gatts_characteristic_add(..) return?

• What does ble_uuid contain?
