https://devzone.nordicsemi.com/f/nordic-q-a/34934/evaluating-compound-expression-within-assertHi, My app was written on Windows PC/MSVC and is ported to nRF52/Keil. In many places I&#39;ve used MSVC assert() macro in the following manners: assert(function(arg1, arg2) == SUCCESS) assert(ptr) assert(ptr &amp;&amp; intvar) etc...

See nrf_assert.h. Without DEBUG_NRF or DEBUG_NRF_USER defined it will be an &quot;if (false)&quot;.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
