Note that a reset usually indicates that you are running into the error handler, where the default behavior is to do a reset. You should then debug in order to find the reason for the reset. <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/">See this post about debugging</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/116568?ContentTypeID=1Tue, 09 Jan 2018 10:31:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e7dd18ae-5ea9-4519-95c8-c421d86cbc14liu<p>Yeah. I just make a rtc timer of 10s to test it. The first 10s to stop the ADV,and next one to restart it. After many times, the system can work normally.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/116570?ContentTypeID=1Tue, 09 Jan 2018 10:26:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:03d99e8f-9ba4-4f9b-b324-24d05d2b00e4Sigurd<p>Did you solve the issue?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/116569?ContentTypeID=1Tue, 09 Jan 2018 10:23:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:226a3783-5b5a-4388-bbed-e34fb6c202c1liu<p>Oh,it&#39;s right.
