Can you please elaborate a bit? Do you want to run the ble_app_uart example from the SDK on your nRF51 DK board? What do you mean that it only works when you connect it with a USB?</p> <p>The nRF51 DK have a nRF51<strong>4</strong>22. However, the nRF51822 and nRF51422 can be considered the exact same chip, but the nRF514 has both ANT and BLE capabilities, while the nRF518 has only BLE.</p> <p>If you want to make an Android app I suggest that you look through our <a href="http://Https://github.com/nordicsemiconductor?utf8=%E2%9C%93&amp;query=android">Android examples on github</a>. <a href="https://developer.android.com/guide/topics/connectivity/bluetooth-le.html">Here</a> is a Android/BLE getting started guide.</p><div style="clear:both;"></div>
