HarmonyOS 鸿蒙Next 蓝牙连续订阅服务问题：应用首次启动订阅成功，再次启动长时间等待无应答

HarmonyOS 鸿蒙Next 蓝牙连续订阅服务问题：应用首次启动订阅成功，再次启动长时间等待无应答
如果设备支持ftms、fec、power等服务，需要在连接上设备的时候，全部开启订阅；应用第一次启动。连接设备后开启这些服务订阅都成功了，但是如果再次启动应用连接设备，就是一直等待。

问题场景描述：

if (characteristicUuid == BleDeviceConstant.FTMS_INDOOR_BIKE_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.FTMS_CONTROL_POINT_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.FTMS_ROWER_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.C2_ROWER_CHARACTER31 ||
  characteristicUuid == BleDeviceConstant.C2_ROWER_CHARACTER32 ||
  characteristicUuid == BleDeviceConstant.C2_ROWER_CHARACTER36 ||
  characteristicUuid == BleDeviceConstant.FEC_READ_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.POWER_MEASUREMENT_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.SPEED_AND_CADENCE_NOTIFY_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.HEART_RATE_NOTIFY_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.MPAS_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.UART_SERVICE_READ_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.BIKE_COMPUTER_SERVICE_READ_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.BIKE_COMPUTER_SERVICE_WRITE_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.BIKE_SARP_SERVICE_WRITE_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.IRAKE_HEART_CHARACTERISTIC ||
  characteristicUuid == BleDeviceConstant.IRAKE_DATA_CHARACTERISTIC) {
  console.error('setNotifyOn characteristicUuid is ' + characteristicUuid);
  await this.setNotifyOn(clientDevice, gattServices[i].characteristics[j]);
  this.setSupportedService(deviceId, characteristicUuid);
}

// 开启通知
private async setNotifyOn(clientDevice: ble.GattClientDevice, bleCharacteristic: ble.BLECharacteristic) {
  try {
    console.error('setNotifyOn setCharacteristicChangeNotification , ' + bleCharacteristic.characteristicUuid);
    await clientDevice.setCharacteristicChangeNotification(bleCharacteristic, true);
    console.error('setNotifyOn setCharacteristicChangeNotification success, ' + bleCharacteristic.characteristicUuid);
  } catch (err) {
    console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
  }
}

问题提出人：备注一下，如果不用异步，就会上来就报错。
