https://devzone.nordicsemi.com/f/nordic-q-a/30908/modes-of-firmware-in-nrf51822I am developing Firmware for NRF51822, S110 in Eclipse. I Heard that there is two mode in Firmware. 1. Debug mode 2. Production(release) mode. Is there anything like that? what is difference between both of them? How to switch to one mode to another?en-USTelligent Community 13Tue, 06 Mar 2018 12:52:36 GMThttps://devzone.nordicsemi.com/thread/123072?ContentTypeID=1Tue, 06 Mar 2018 12:52:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:efe043e0-51ca-4a19-9815-a3b05ab60555Rune Holmgren<p>There isn&#39;t a general mode selection where you can choose &quot;debug mode&quot; and &quot;production mode&quot; for the chip itself. It&#39;s common to find IDE/compiler features intended for development which may be disabled by setting a mode in the IDE, but this is not specific to our chip.</p> <p>Generally, you want to debug firmware with features like logging turned on and sometimes with optimization turned off. Later when it is time to release its common to remove such development features to focus on the performance and efficiency of the device.</p> <p>Best regards,<br />Rune Holmgren</p><div style="clear:both;"></div>
