https://devzone.nordicsemi.com/f/nordic-q-a/13180/nrf51822-qfaca1I have nrf51822 QFACA1 and STM32f407VG. I&#39;m programming nrf51822 QFACA1 using STM32f407VG SWD pings. And now I want programming BLE nrf51822 QFACA1 but I can&#39;t find any working example on nrf51822 QFACA1. How can I programming nrf51822 QFACA1 (BLE) ?en-USTelligent Community 13Fri, 15 Apr 2016 13:21:40 GMThttps://devzone.nordicsemi.com/thread/50253?ContentTypeID=1Fri, 15 Apr 2016 13:21:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bee72671-4aaf-41de-bf59-4d5289a89d0eStefan Birnir Sverrisson<p>Hi</p> <p>The nRF51822 QFAC is a third revision WLCSP version of the nRF51 Series. For development with third revision nRF51 series (nRF51822 or nRF51422) you generally use the nRF51-DK development board. Are you working with the nRF51-DK or custom PCB with nRF51822 QFAC? For programming the nRF51-DK, the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51/dita/nrf51/nrf51_development.html?cp=2_1">nRF51 Development Kit User Guide</a> provides information on how to connect the nRF51-DK board, and what tools are needed in order to start development, see &quot;Getting started&quot; chapter.</p> <p><a href="https://devzone.nordicsemi.com/tutorials/2/">Here is a tutorial</a> on how to set up the kit and program an example, and <a href="https://devzone.nordicsemi.com/tutorials/4/">this tutorial</a> is the followup one with info on how to program a BLE application to the nRF51-DK</p><div style="clear:both;"></div>
