From the reading I have done, I believe you are correct when you asked about flashing the softdevice before the application, but I have not found how to do it. Is the correct method to do the batch build for the soft, then flash it, then build the other and flash? If that is the correct way, sometimes if I build the soft, it will not let me flash it. Exiting the IDE seems to help.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/118973?ContentTypeID=1Mon, 29 Jan 2018 10:25:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9edca134-df9f-4332-ac17-3b2789b624bdJoakim Jakobsen<p>Hi Brian.<br /> Did you remember to flash the softdevice to your DK before flashing your application?<br /> Best regards.</p><div style="clear:both;"></div>
