We recommend using the nRF Connect Programmer instead, which is a part of&nbsp;<a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-desktop">nRF Connect for Desktop</a>. For information about nRF Connect Programmer see&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ug_nc_programmer/UG/nrf_connect_programmer/ncp_introduction.html">this link</a>.</p> <p>The Programmer application can be used to program Nordic devices with .hex files, and you can use it for both applications and softdevices.</p> <p>Best regards,</p> <p>Marte</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/302721?ContentTypeID=1Wed, 31 Mar 2021 12:08:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:04f2f019-6166-412f-8382-439d8eb0860cDaveC<p>Correction to above:</p> <ul> <li>The Application Start address for Soft Device 6.1.1<span>&nbsp;</span><span>140_nrf52_6.1.1.hex is&nbsp;</span>&nbsp;0x26000</li> </ul><div style="clear:both;"></div>
