Android BLE Connection time interval

Question

I am developing a BLE application on Nexus 4 using Android BLE API. I have a few questions/doubts:

1) Is there a way to set/override the connection or notification i

Answer 1

I met auto disconnection problem same as your second question. Two ways to solve it:

1) Manually pair you Android device with the remote device through Bluetooth setting before running your application.

2) Or you can programmatically pair them in your code. Here's the pairing code I found online, which works for me

private void pairDevice(BluetoothDevice device) {
        try {
            Log.d("pairDevice()", "Start Pairing...");
            Method m = device.getClass()
                    .getMethod("createBond", (Class[]) null);
            m.invoke(device, (Object[]) null);
            Log.d("pairDevice()", "Pairing finished.");
        } catch (Exception e) {
            Log.e("pairDevice()", e.getMessage());
        }
    }
