Question

I am making an app that requires the user’s bluetooth discoverability/visibility timeout to “Never time out”.

I use the following code to ask the user to change the current settings.

Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 0);           
startActivity(discoverableIntent);

However, I don’t want to bother the user if bluetooth discoverability is already on.

Is there a way to get the device’s current discoverability timeout?

Answer 1

You can use the the following:

BluetoothAdapter ba = BluetoothAdapter.getDefaultAdapter();
if (ba.getScanMode() != BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE)
{
    //Launch the intent to set timeout
}

You should also make sure that the Adapter is turned on.
