如何仅扫描广告包BLE

Question

While scanning for advertising beacons with startLeScan method, this method also request peripheral device for scan response and stores it in scanRecord. I only want to scan for advertising payload I don't want to send request scan response to peripheral device

my code to scan:

mBluetoothAdapter.startLeScan(mLEScanCallback);
private BluetoothAdapter.LeScanCallback mLEScanCallback = new BluetoothAdapter.LeScanCallback() {
    @Override
    public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord) {

    }
};

Answer 1

No, I do not believe there is any way to turn off scan response requests. Android 4.3-4.4 BLE APIs provide no scanning options at all (other than a service uuid filter). The new Android 5.0 APIs have added some scan options, but none that halt scan responses. See here:
