I flashed SD110 on the Demo Board with nRFgo Studio and compiled and loaded the proximity example with the Keil Compiler. Everything worked like explained in the user manualen-USTelligent Community 13Sun, 11 Oct 2015 12:13:37 GMThttps://devzone.nordicsemi.com/thread/35010?ContentTypeID=1Sun, 11 Oct 2015 12:13:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:31ff221e-204b-4427-b6bd-916ac95d2257sfueller<p>sorry for the delaied answer. I did not have time to continue work with the nordic chip, because the priorities changed.</p> <p>I will continue my work in some weeks and will check your suggestions then and comment the results here.</p> <p>Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35009?ContentTypeID=1Tue, 29 Sep 2015 08:50:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:48995fd0-6cdc-494a-89b0-c98e471b427fMartinBL<p>Hi.</p> <ul> <li>Are you able to run a simple LED blinky example without a softdevice? This is a simple way of knowing whether the problems lies &quot;before or after programming&quot; or if it is e.g. a <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51.v1.0.0/pdflinks/nrf51_comp_matrix.html?resultof=%22%63%6f%6d%70%61%74%69%62%69%6c%69%74%79%22%20%22%63%6f%6d%70%61%74%22%20">Softdevice, SDK and/or nRF51 revision incompatibillity issue</a>.</li> <li>Are you able to read the chip markings on top of the nRF51 to determine what IC revision it is?</li> <li>What Softdevice version are you using?</li> <li>What SDK are you using?</li> <li>Have you specified the correct Softdevice in the example? The proximity example in SDK 9.0.0 can often be used with several different SDs, but you will need to specify which one in the Target options -&gt; C/C++ options.</li> </ul><div style="clear:both;"></div>
