Hi Stian, thank you for the previous answer. I think that the part of the example concerning my case is "Handling data received over UART", with the first row saying "Data that is received from the UART undergoes certain checks before it is relayed to the BLE peer using the Nordic UART Service." What is still unclear to me is how to set up an interface between Arduino and the board, and which kind of protocol to use.

Android version < 4.3 does not have native BLE support (except some Samsung phones which have their own BLE API, but the nRF UART app does not work with this). So you have to have at least 4.3 in order to use BLE at all.

Thanks a lot for your answer. I will start from that, but is there a versione of your apps working with previous versions of Android? They all require at least 4.3

Hi, you can find the SDK here, and the documentation here. Maybe the UART example is a good place to start for you. You can find the documentation for it here. You can download the Nordic nRF UART app to your phone, using App Store or Google Play, to receive and transmit data from/to the nRF51-DK board. The app is also open source if you want to use this as a starting point for creating your own app.
