I am looking something on the level of how to connect the Arduino with a NRF51822 module and which interfaceen-USTelligent Community 13Thu, 19 Mar 2015 10:19:20 GMThttps://devzone.nordicsemi.com/thread/21315?ContentTypeID=1Thu, 19 Mar 2015 10:19:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:35228269-c871-4bee-8eb7-9505758cb4fcAsbj&#248;rn<p>You can connect the nRF51822 to an Arduino. You can use either UART or SPI, it depends on what you prefer, I guess the most common is to use UART. You have to implement the UART application on the nRF51822 to handle the communication with the Arduino, but if it&#39;s just to test RF functionality you could re-use the ESB example available in the <a href="http://developer.nordicsemi.com/">nRF51 SDK</a> and add the UART to receive commands.</p><div style="clear:both;"></div>
