I am trying to make all the prints in my application to be displayed properly via UART correctly. So, i am using the sample application as per the path: &lt;SDKen-USTelligent Community 13Tue, 16 Nov 2021 13:38:12 GMThttps://devzone.nordicsemi.com/thread/339240?ContentTypeID=1Tue, 16 Nov 2021 13:38:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5d92db90-8c24-41f4-a781-cea63856e983nagesh.shamnur<p>sorry for the trouble, that was an issue in my application code. it is rectified now.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/335670?ContentTypeID=1Mon, 25 Oct 2021 09:33:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa8ac79c-98ca-4cd3-9af9-cc204abb35bfJared<p>Hi there,</p> <p></p> <p>Are you using a completely unmodified version of the UART peripheral example?

If it enters the error handler, what does the call stack look like? Does it specify from where the error handler was called from?</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
