https://devzone.nordicsemi.com/f/nordic-q-a/69764/app-crashes-on-sdk-1-4-1Hi, I&#39;ve just moved to nRF Connect 1.4.1 from 1.3.0 and my application started crashing at random place. Also, I&#39;ve started seeing the following error in the output and the app doesn&#39;t accept AT commands anymore. &quot;[00:00:00.000,183] &lt;inf&gt; at_hosten-USTelligent Community 13Tue, 22 Dec 2020 13:41:40 GMThttps://devzone.nordicsemi.com/thread/286312?ContentTypeID=1Tue, 22 Dec 2020 13:41:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6bb303cc-8831-42ef-b468-b8aa8868ae13Heidi<p>Hi!</p> <p></p> <p>Which application is it you are running?
