想请教一下，iar编译报error，
- #if defined (add_vbat_service)
- uint8_t battery_data = 85;
- ble_advdata_service_data_t service_data;
- #endif
- memset(&init, 0, sizeof(init));
- init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
- //init.advdata.name_type = BLE_ADVDATA_NO_NAME;

- 提示Error[Pe550]: variable "service_data" was set but never used D:\nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_template\main.c 632
我明明已经use了，怎么还有错误？？
条件编译我也有的
