            mBtAdapter.cancelDiscovery();
           Intent intent = new Intent(DevicesList.this, FindIT.class);
            intent.putExtra("name", NAME);
            intent.putExtra("rssi", RSSI);
            startActivity(intent);
        }
    });

here is the code i use to send the intent

Maybe you are looking for something like this:

Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("BLUETOOTH_NAME", bluetoothName);
intent.putExtra("RSSI", rssi);
startActivity(intent);

In this case you save your data in the intent and pass it to the next activity every time you go from one activity to another. Then you can get your data in the new activity like this:

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String bluetoothName = extras.getString("BLUETOOTH_NAME");
    String rssi = extras.getString("RSSI");
}
