NRF51-DK + Arduino

Hi everyone, I have been given a nRF51-DK board and I should use it to send data retreived from a sensor to it through Arduino, to finally receive it in my cell phone. I am new to Nordic products and to bt world too, I would like to know if there are some resources to help me with my work. I saw somewhere that there should be a SDK for such tasks, but I am a little bit confused.

  • 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.

  • 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.
