That might explain why you get the error. I would recommend using the programmer app, nrfjprog, or the Softdevice flash target in Keil to program the Softdevice.</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-c4378ef3c0694e96952d6b2ef1598e9f/Capture.PNG" />&nbsp;</p><div style="clear:both;"></div>
