HarmonyOS 鸿蒙Next 蓝牙BLE调用writeCharacteristicValue时报错2900099: Operation failed

在确认建立连接并且获取特征值信息之后调用writeCharacteristicValue写入数据会遇到BussinessError 2900099: Operation failed的报错，在调用前有确认连接状态为已连接。 进行BLE蓝牙开发，手机作为Client端连接激光测距蓝牙模块进行读写通信，当手机作为Client端时连接server端，可以成功建立连接，并且获取特征值信息，log可以打印。

步骤: 问题代码如下:

// 写入数据
writeBLECharacteristicValue(msg:BluetoothMsgType, isHex:boolean)
{
  if (this.mGattClientDevice !== undefined) {
    Logger.info(TAG, "the private mGattClientDevice is= " + this.mGattClientDevice)
  }
  let data: string = bleMsgDetail.getValue(msg);
  Logger.info(TAG, "writeBLECharacteristicValue-data = " + data + " isHex = " + isHex)
  let byteArray: Uint8Array = isHex ? this.hexStrToBytes(data) : new util.TextEncoder().encodeInto(data);
  Logger.info(TAG, "ecCharacteristicWrite is: " + this.ecCharacteristicWrite?.serviceUuid)
  if (this.ecCharacteristicWrite == undefined) {
    Logger.info(TAG, "ecCharacteristicWrite is undefined")
    // return;
    let mCharacteristicWrite: ble.BLECharacteristic = {
      characteristicUuid: this.ecCharacteristicWrite.characteristicUuid,
      serviceUuid: this.ecCharacteristicWrite.serviceUuid,
      characteristicValue: byteArray,
      descriptors: this.ecCharacteristicWrite.descriptors,
    }
    // 设置回复形式 + 开始写数据
    Logger.info(TAG, "in writeBLECharacteristicValue connection state is: " + this.bleConnectionStateInfo)
    if (this.bleConnectionStateInfo === 'STATE_CONNECTED') {
      try {
        Logger.info(TAG, 'bluetooth writeCharacteristicValue start');
        if (this.mGattClientDevice !== undefined) {
          this.mGattClientDevice.writeCharacteristicValue(this.ecCharacteristicWrite, ble.GattWriteType.WRITE,
            this.writeCharacteristicValueCallBack);
          // Logger.info(TAG, 'bluetooth writeCharacteristicValue success'); 
        }
      } catch (err) {
        Logger.error(TAG, 'writeCharacteristicValue errCode: ' + (err as BusinessError).code + ', errMessage: ' +
        (err as BusinessError).message);
      }
    }
  }
  writeCharacteristicValueCallBack(code:  BusinessError  )  {
    if (code != null) {
      Logger.error(TAG, "error with writeCharacteristicValue" + (code) + ', errMessage: ' + (code.message));
      return;
    }
    Logger.info(TAG, 'bluetooth writeCharacteristicValue success');
  }
}
