Have a look at the nRFtoolbox or nRF proximity. In the long run, if you are planning on launching a product, I would recommend to create your own app to handle the connection.</p> <p>Q2: <a href="https://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF51822">I would recommend you to have a look at the nRF51822 as this is a much more flexible solution.</a> The nRF8002 is a single chip BLE solution, but it comes with a limited set of functionality.
