Don&#39;t remember whether that is possible in the first place and will likely need manual configuration.</p> <p>The other condition is that new SD+new BL must fit in the slot space for the app. Could be rather tight in the NRF52832 depending on which SD you intended to use.</p><div style="clear:both;"></div>
