状态未传递给usecallback

Question

我正在执行BLE项目并成功连接到设备。在流传输数据时，我从事件中获取了心率数据。但是状态没有传递给useCallback函数，并定义为空数组。

代码

const samples = 200
const sampleData = _.fill(Array(samples), 0)
const [heartRateValues, setHeartRateValues] = useState(sampleData)

const [heartRateMeasurementListener, setHeartRateMeasurementListener] = useState(null)

useEventListener(
   'characteristicvaluechanged',
   handleHeartRateMeasure,
   heartRateMeasurementListener
);

const handleHeartRateMeasure = useCallback(async(event) => {
    console.log(heartRateValues) // <----- [] empty
},[heartRateValues])

const connectBLE = async() => {
    let res = await bleConnect()
    // ble device successfully connected.
    if(res){
        startNotificationsHeartRateMeasurement().then((heartRateMeasurementListener) => {
            setHeartRateMeasurementListener(heartRateMeasurementListener)
        })
    }
});

BLE

export const startNotificationsHeartRateMeasurement = () => {
    return _startNotifications('heart_rate_measurement');
}
function _startNotifications(characteristicUuid) {
   let characteristic = _characteristics.get(characteristicUuid);
   return characteristic.startNotifications()
        .then(() => characteristic);
}

UseEventListener

export const useEventListener = (eventName, handler, element = window) => {
  // Create a ref that stores handler
  const savedHandler = useRef();

  // Update ref.current value if handler changes.
  // This allows our effect below to always get latest handler ...
  // ... without us needing to pass it in effect deps array ...
  // ... and potentially cause effect to re-run every render.
  useEffect(() => {
    savedHandler.current = handler;
  }, [handler]);

  useEffect(
    () => {
      // Make sure element supports addEventListener
      // On 
      const isSupported = element && element.addEventListener;
      if (!isSupported) return;
    
      // Create event listener that calls handler function stored in ref
      const eventListener = event => savedHandler.current(event);
    
      // Add event listener
      element.addEventListener(eventName, eventListener);
    
      // Remove event listener on cleanup
      return () => {
        element.removeEventListener(eventName, eventListener);
      };
    },
    [eventName, element] // Re-run if eventName or element changes
  );
};

问题

heartRateValues为空[]，而不是值数组。
