You need to download the SDK, found on <a href="https://developer.nordicsemi.com/nRF5_SDK/">this page</a>.</p> <p>Keil uVision 4 can be <a href="https://www.keil.com/demo/eval/armv4.htm">downloaded here</a>.</p> <p>You are looking at a very old example, and the board you are using is also old. I would recommend you buying a <a href="http://www.nordicsemi.com/eng/Products/nRF51-DK">nRF51 DK</a> (or better, <a href="http://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52-DK">nRF52 DK</a>) for doing your development. This have better support, and the SDK have improved much from v6.1.0 to the latest <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk/keydef/PLUGINS_ROOT/com.nordic.infocenter.sdk5.v14.0.0/index.html?cp=4_0_0">v14.0.0</a>.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
