You could adjust the flash size of the project so that you would get an error if the app becomes too large, but it is normally not needed. You should updated the board definition though, as explained in the tutorial in the section&nbsp;&quot;Adapt a BLE example (<strong><em>with</em></strong> SoftDevice) and program it using nRF Connect Programmer&quot;.<span style="font-family:inherit;">&nbsp;</span></p><div style="clear:both;"></div>
