Hi. 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?

The nRF51 DK have a nRF51422. 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.

If you want to make an Android app I suggest that you look through our Android examples on github. Here is a Android/BLE getting started guide.

I'm afraid I don't have anything more for you than the two links above. There is also a proximity example in the SDKs.
