https://devzone.nordicsemi.com/f/nordic-q-a/43896/simple-scanner-application-stops-after-1-weekHello, I have developed simple scanner application that scans for beacons (apple, nordic and of own type). It prints data about beacons over UART. I have installation where I have 25 such scanners. I installed them ~10 days ago.

Nothing indicates that the scan parameters that you have would cause this. My suspicion is that the issue is on the UART client side.</p> <ul> <li>What client have you connected the beacons to? A PC? What program is running on the PC?</li> <li>Was there any activity on the data line when the beacons had stopped? Where they still scanning?&nbsp;</li> <li>Do you have any sniffer log of the event?</li> <li>I would recommend connecting one of the IC to a debugger and run it in debug mode until you experience a similar issue. Then print the debug code that is thrown so that we can analyze the problem further.</li> </ul> <p>Best regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
