Compile error in SDK12 with BSP_SIMPLEhttps://devzone.nordicsemi.com/f/nordic-q-a/16985/compile-error-in-sdk12-with-bsp_simpleHi nRF support, In order to minimize the code size, I tried to enable define the macro BSP_SIMPLE, then I got the below error: *** Using Compiler &#39;V5.06 update 2 (build 183)&#39;, folder: &#39;C:\Keil_v5\ARM\ARMCC\Bin&#39; Rebuild target &#39;nrf51422_xxac&#39; compilingen-USTelligent Community 13Tue, 11 Oct 2016 12:49:30 GMTRE: Compile error in SDK12 with BSP_SIMPLEhttps://devzone.nordicsemi.com/thread/65165?ContentTypeID=1Tue, 11 Oct 2016 12:49:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:502525b6-a72a-4b43-8bdc-5f8f27387689J&#248;rgen Holmefjord<p>Hi,</p> <p>You will have to remove bsp_btn_ble.c, and other files that use these defines, from your project. You also have to remove/comment out any use of functions defined in this file, in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/lib_button.html?cp=4_0_0_3_6">Button handling library</a> (app_button) or other related files.</p> <p>Check out line 35-41 in bsp.h found in <code>examples\bsp\</code> in SDK12 for details about what is left out by BSP_SIMPLE.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
