How to programmatically set Discoverable time without user confirmation?

I usually use this

C#

private void ensureDiscoverable() {
        if(D) Log.d(TAG, "ensure discoverable");
        if (mBluetoothAdapter.getScanMode() !=
                BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE) {
            Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
            discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
            startActivity(discoverableIntent);
        }
    }

But that prompts a user confirmation. Is there a way to bypass this programmatically?

I eventually found this

but unfortunately the setDiscoverableTimeout doesnt work.

Why does this need a user acknowledge? That is from a tutorial her:

You should change/overwrite it when you want to change that method.

I know that sample very well - every time you do that discoverableIntent, that prompts the user for confirmation - that is what I want to avoid.

AFAIK it is a design feature of the Bluetooth adapter that the user of the device must start or stop the discoverabilty. That is why the action is called ACTION_REQUEST_DISCOVERABLE and not ACTION_DISCOVERABLE.

Yes, but the taking into account there is a "action request enable" to enable bluetooth, there is also a way to enable programatically BT without user interaction (using .enable), I was wondering if it possible to do the same with discoverable timeout.
