QT蓝牙广播时间间隔设置

Question

程序需要广播自定义数据。

ble_Controller=QLowEnergyController::createPeripheral();
QLowEnergyAdvertisingData advertisingData;
    advertisingData.setDiscoverability(QLowEnergyAdvertisingData::DiscoverabilityGeneral);
    advertisingData.setIncludePowerLevel(false);
    advertisingData.setManufacturerData(0xf0ff,"123456");
    //advertisingData.setRawData("123456");
    //! [Start Advertising]
    ble_Controller->setRemoteAddressType(QLowEnergyController::RandomAddress);
    QLowEnergyAdvertisingParameters advPar;
    advPar.setMode(QLowEnergyAdvertisingParameters::AdvInd);
    advPar.setInterval(100,200);
     qDebug()<<"mode:"<<advPar.mode();
     qDebug()<<"max:"<<advPar.maximumInterval();
     qDebug()<<"min:"<<advPar.minimumInterval();
    ble_Controller->startAdvertising(advPar, advertisingData,
                                   QLowEnergyAdvertisingData());

使用安卓手机广播，使用nrf connect 接收数据。
得到数据正确但接收时间间隔怎么修改都是1000ms左右。
