HarmonyOS蓝牙搜索报错BussinessError 2900100如何解决？

Question

关于harmonyos进行蓝牙搜索时，调用 bluetoothManager.startBluetoothDiscovery();出现连接蓝牙设备失败： Error: BussinessError 2900100: trans exception.这个报错，请问有人知道该如何解决吗
try {

  console.info("faxian");
  // 检查蓝牙是否开启
  const state =  bluetoothManager.getState();
  if (state !== bluetoothManager.BluetoothState.STATE_ON) {
    // 请求用户开启蓝牙
    bluetoothManager.enableBluetooth();
    console.info("请求打开蓝牙");
  }
  else
  {
    console.info("已打开蓝牙");
  }
  // 扫描
  let deviceId;
  function onReceiveEvent(data) {
    deviceId = data;
    console.info('BLE scan device find result = '+ JSON.stringify(data));
    console.info("120");
  }

  bluetoothManager.BLE.on("BLEDeviceFind", onReceiveEvent);
    // bluetoothManager.startBluetoothDiscovery();
    bluetoothManager.startBluetoothDiscovery();
    bluetoothManager.BLE.startBLEScan(
      [{
        deviceId:"22:4B:B2:C9:09:24",
        name:"test",
        serviceUuid:"00001888-0000-1000-8000-00805f9b34fb"
      }],
      {
        interval: 500,
        dutyMode: bluetoothManager.ScanDuty.SCAN_MODE_LOW_POWER,
        matchMode: bluetoothManager.MatchMode.MATCH_MODE_AGGRESSIVE,
      }
    );
} catch (err) {
  console.error("连接蓝牙设备失败：", err);
  console.info("113");
}

使用的是官方提供的API，希望各位大佬帮忙出出注意

错误代码“2900100: trans exception”表明在蓝牙传输过程中发生了异常。
deviceId:"22:4B:B2:C9:09:24",
name:"test",
serviceUuid:"00001888-0000-1000-8000-00805f9b34fb"，
这三个参数各自都需要重新拿取，需要扫描附近设备，将设备值拿取到，你的代码不能直接复制粘粘，因为这个是案例，需要根据使用情况做出修改
