https://devzone.nordicsemi.com/f/nordic-q-a/24302/raspberry-pi-with-nrf51422-nodesi to all, I have just bought NRF51 DK from arrow.com I couldn&#39;t found one in Turkey. I am not new to C programming but I&#39;m new to ARM architecture. I will be brief. I want to create a home automation sensor node. I will use around 16-20 sensor node anden-USTelligent Community 13Mon, 14 Aug 2017 09:09:11 GMThttps://devzone.nordicsemi.com/thread/95665?ContentTypeID=1Mon, 14 Aug 2017 09:09:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a8572b42-9c67-48ee-9e15-f4f862927b56bjorn-spockeli<p>Yes, as Nguyen Hoan Hoang suggests you should take a look at the tutorials, specifically the</p> <ul> <li><a href="https://devzone.nordicsemi.com/tutorials/5">Bluetooth low energy Advertising, a beginner&#39;s tutorial</a></li> <li><a href="https://devzone.nordicsemi.com/tutorials/8">Bluetooth low energy Services, a beginner&#39;s tutorial</a></li> <li><a href="https://devzone.nordicsemi.com/tutorials/17">Bluetooth low energy Characteristics, a beginner&#39;s tutorial</a></li> </ul> <p>They will give you a good understanding of what you need to do on the nRF51 side. As for the Raspberry Pi side I recommend using the setup described <a href="https://devzone.nordicsemi.com/question/161322/ble-gateway-to-a-web-server/?answer=161432#post-id-161432">here</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/95664?ContentTypeID=1Sun, 13 Aug 2017 05:07:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:36c899c8-1e0d-42f9-a985-7f86e7ce25eaNguyen Hoan Hoang<p>Click on the Tutorial menu above. That is where you get started. There are also many blogs about free alternative development environment.
