https://devzone.nordicsemi.com/f/nordic-q-a/3572/nrf51-ibeacon-application-problemDear all, I tried to program and test the iBeacon application on the s110 folder from nordic examples. The code on the Cortex-M0 has problem. Seems during programming the start-up gets some problem and code can&#39;t run at all!

The example in the SDK uses an external 32 kHz crystal. If your board doesn&#39;t have any external 32 kHz crystal, the application will not run. If your board doesn&#39;t have an external low frequency clock, the source in SOFTDEVICE_HANDLER_INIT(..) should be changed to one of the RC oscillator options.</p><div style="clear:both;"></div>
