But the problem is that we found it stop advertising unexpectedly. Yes, it advertise a certain time before it stops. The frequency is very low and it&#39;s very difficult to reproduce it. I just doubt that if the SD is corrupted due to unknown reason. Any suggestion ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55384?ContentTypeID=1Wed, 15 Jun 2016 10:12:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9d7a767f-9bfc-438a-abd9-566af34d7b9aPetter Myhre<p>If you have started to advertise, this should continue until a timeout is reached, or a connection is made. Could you please try to explain what kind of behavior you expect? Does this happen every time you test? Does it advertise a certain time before it stops? How have you set up advertising in your application?</p><div style="clear:both;"></div>
