https://devzone.nordicsemi.com/f/nordic-q-a/41488/programming-softdevice-apiHey all, So I&#39;m new to the Nordic world and I am having some trouble programming the SoftDevices API. After I compile my code, I get the S112 hex file and try to use this to program to my device, however it just throws an error every time.

I have noticed that there are a decent amount of blank areas in the SoftDevices hex file; not sure if this is normal or not, but just throwing it out there in case it&#39;s indicative of something.[/quote] <p>If you got the SoftDevice from the SDK folder and you haven&#39;t&nbsp; modified that file then there should not be any problems.</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
